With the 1.1.X version of MariaDB ColumnStore, there should be no versions of MariaDB Server or MySQL pre-installed on the OS before a MariaDB ColumnStore binary or RPM is installed on the system. If you have an installation of MariaDB server, uninstall it before proceeding.
Before installing MariaDB ColumnStore, there is some preparation necessary. You will need to determine the following, refer the MariaDB ColumnStore Architecture Document for additional information.
MariaDB ColumnStore is certified to run on:
RHEL/CentOS v6, v7
Ubuntu 16.04 LTS
Debian v8, v9
but it should run on any recent Linux system.
Make sure the same OS is installed on all the servers for a multi-node system.
Make sure the locale setting on all servers are all the same.
To set locale to en_US and UTf-8, run:
# localedef -i en_US -f UTF-8 en_US.UTF-8
Information your system administrator must provide you before you start installing MariaDB ColumnStore:
Example for 3 PM, 1UM system, these are the steps required to configure PM-1 for passwordless ssh. The equivalent steps must be repeated on every PM in the system. The equivalent steps must be repeated on every UM in the system if the MariaDB ColumnStore Data Replication feature is enabled during the install process.
[[email protected] 1 ~] $ ssh-keygen [[email protected] 1 ~] $ ssh-copy-id -i ~/.ssh/id_rsa.pub pm-1 [[email protected] 1 ~] $ ssh-copy-id -i ~/.ssh/id_rsa.pub pm-2 [[email protected] 1 ~] $ ssh-copy-id -i ~/.ssh/id_rsa.pub pm-3 [[email protected] 1 ~] $ ssh-copy-id -i ~/.ssh/id_rsa.pub um-1
If utilizing ssh-keys and will be utilizing the MariaDB ColumnStore Data Redundancy feature, make sure you setup an ssh-key on the PM1 node to itself. This is required for Data Redundancy feature.
If utilizing ssh-keys and will be utilizing the MariaDB ColumnStore Data Replication feature, make sure you setup an ssh-key between all UM nodes. And if you enabled the Local Query Feature, will also need between all UM nodes and all PM nodes.
MariaDB ColumnStore is quite flexible regarding networking. Some options are as follows:
The MariaDB ColumnStore daemon utilizes port 3306.
You must reserve the following ports to run the MariaDB ColumnStore software: 8600 - 8630, 8700, and 8800
MariaDB ColumnStore supports being able to configure with different Storage options.
DBRoots are the MariaDB ColumnStore Datafile containers or directories. For example on a root install, they are /usr/local/mariadb/columnstore/data<N> where N is the dbroot number.
IMPORTANT: When using Storage (extX, NFS, etc), setup to have the MariaDB front-end data and the DBRoots back-end data files mounted. Don't setup a mount where the actually MariaDB Columnstore package as a whole is mounted, i.e. /usr/local/mariadb or /usr/local/mariadb/columnstore.
This would included mounts for:
If you are using local disk to store the database files, the DBRoot directories will be created under the installation directory, for example /usr/local/mariadb/columnstore/data<N> where N is the DBRoot number. You should setup to have 1 DBRoot per Performance Module when configuring the system.
Use of soft-links for the Data. If you want to setup an install where the Data is stored out in a separate directory in the case you have limit amount local storage, this can be done. It is recommended that the softlinks be setup at the Data Directory Levels, like mariadb/columnstore/data and mariadb/columnstore/dataX. With this setup, you can perform upgrades using any of the package types, rpm, debian, or binary. In the case where you prefer OR have to set a softlink at the top directory, like /usr/local/mariadb, you will need to install using the binary package. If you install using the rpm package and tool, this softlink will be deleted when you perform the upgrade process and the upgrade will fail.
If you are using a SAN to store the database files, the following must be taken into account:
The following example shows an /etc/fstab setup for 2 dbroots total for all PMs, but they can setup any disk type they want:
/dev/sda1 /usr/local/mariadb/columnstore/data1 ext2 noatime,nodiratime,noauto 0 0 /dev/sdd1 /usr/local/mariadb/columnstore/data2 ext2 noatime,nodiratime,noauto 0 0
There are optimizations that should be made when using MariaDB ColumnStore listed below. As always, please consult with your network administrator for additional optimization considerations for your specific installation needs.
/sbin/ifconfig eth0 txqueuelen 10000
# increase TCP max buffer size net.core.rmem_max = 16777216 net.core.wmem_max = 16777216 # increase Linux autotuning TCP buffer limits # min, default, and max number of bytes to use net.ipv4.tcp_rmem = 4096 87380 16777216 net.ipv4.tcp_wmem = 4096 65536 16777216 # don't cache ssthresh from previous connection net.ipv4.tcp_no_metrics_save = 1 # recommended to increase this for 1000 BT or higher net.core.netdev_max_backlog = 2500 # for 10 GigE, use this net.core.netdev_max_backlog = 30000 NOTE: Make sure there is only 1 setting of net.core.netdev_max_backlog in the /etc/sysctl.conf file.
To check the current value:
To set the current value until the next reboot:
sysctl -w vm.vfs_cache_pressure=10
To set the value permanently across reboots, add the following to /etc/sysctl.conf:
vm.vfs_cache_pressure = 10
The default setting of 022 in /etc/profile is what is recommended. It it required that it the setting doesn't end with a 7, like 077. Example, on a root install, mysqld that runs as 'mysql' user needs to be able to read the MariaDB ColumnStore configuration file, Columnstore.xml. So a last digit of 7 would prevent this and cause the install to fail.
The current umask can be determined:
A value of 022 can be set in the current session or in /etc/profile as follows:
The MariaDB ColumnStore utilizes these ports 3306, 8600 - 8630, 8700, and 8800. So on multi-node installs, these ports will need to be accessible between the servers. So if there is any firewall software running on the system that could block these ports, either that firewall would need to be disabled as shown below or the ports listed above will need to be configured to allow both input and output on all servers within the firewall software. You will also want to allow these ports to be passed though on any routers that might be connected between the servers.
To disable any local firewalls and SELinux on mutli-node installs
You must be a Root user.
CentOS 6 and systems using iptables
#service iptables save (Will save your existing IPTable Rules) #service iptables stop (It will disable firewall Temporarly)
To Disable it Permanentely:
#chkconfig iptables off
CentOS 7 and systems using systemctl with firewalld installed
#systemctl status firewalld #systemctl stop firewalld #systemctl disable firewalld
Ubuntu and systems using ufw
#service ufw stop (It will disable firewall Temporary)
To Disable it Permanentely:
#chkconfig ufw off
#/sbin/rcSuSEfirewall2 status #/sbin/rcSuSEfirewall2 stop
To disable SELinux,
edit file "/etc/selinux/config" and find line; SELINUX=enforcing Now replace it with, SELINUX=disabled
MariaDB ColumnStore requires that the boost package of 1.53 or newer is installed.
For Centos 7, Ubuntu 16, Debian 8, SUSE 12 and other newer OS's, you can just install the boost packages via yum or apt-get.
# yum -y install boost
# apt-get -y install libboost-all-dev
For CentOS 6, you can either download and install the MariaDB Columnstore Centos 6 boost library package or install the boost source of 1.55 and build it to generate the required libraries. That means both the build and the install machines require this.
How to download, go to binaries download page and download "centos6_boost_1_55.tar.gz"
Click All Versions - > 1.0.x -> centos -> x86_64
Install package on each server in the cluster
wget https://downloads.mariadb.com/ColumnStore/1.0.14/centos/x86_64/centos6_boost_1_55.tar.gz tar xfz centos6_boost_1_55.tar.gz -C /usr/lib ldconfig
Downloading and build the boost libraries:
NOTE: This means that the "Development Tools" group install be done prior to this.
yum groupinstall "Development Tools" yum install cmake
Here is the procedure to download and build the boost source:
cd /usr/ wget http://sourceforge.net/projects/boost/files/boost/1.55.0/boost_1_55_0.tar.gz tar zxvf boost_1_55_0.tar.gz cd boost_1_55_0 ./bootstrap.sh --with-libraries=atomic,date_time,exception,filesystem,iostreams,locale,program_options,regex,signals,system,test,thread,timer,log --prefix=/usr ./b2 install ldconfig
For SUSE 12, you will need to install the boost-devel package, which is part of the SLE-SDK package.
SUSEConnect -p sle-sdk/12.2/x86_64 zypper install boost-devel
Make sure these packages are installed on the nodes where the MariaDB ColumnStore packages will be installed:
# yum -y install expect perl perl-DBI openssl zlib file sudo libaio rsync snappy net-tools numactl-libs nmap jemalloc
# apt-get -y install tzdata libtcl8.6 expect perl openssl file sudo libdbi-perl libboost-all-dev libreadline-dev rsync libsnappy1v5 snappy net-tools libnuma1 nmap libjemalloc1
# apt-get install expect perl openssl file sudo libdbi-perl libboost-all-dev libreadline-dev rsync libsnappy1 net-tools libnuma1 nmap libjemalloc1
# apt-get install expect perl openssl file sudo libdbi-perl libboost-all-dev libreadline-dev rsync net-tools libsnappy1v5 libreadline5 libaio1 libnuma1 nmap libjemalloc1
zypper install expect perl perl-DBI openssl file sudo libaio1 rsync net-tools libsnappy1 libnuma1 nmap jemalloc
In 1.1.0 and later, MariaDB ColumnStore supports Data Redundancy by utilize the third party software GlusterFS. So if you wanted to utilize the Data Redundancy feature, you would need to install the the GlusterFS package on all nodes that will be used as Performance Modules. Requires 3.3.1 version or later.
# yum -y install centos-release-gluster # yum -y install glusterfs glusterfs-fuse glusterfs-server start / enable service: # systemctl enable glusterd.service # systemctl start glusterd.service
# sudo apt-get install glusterfs-server attr start / enable service: # sudo systemctl start glusterfs-server.service # sudo systemctl enable glusterfs-server.service
# apt-get -y install glusterfs-server attr start / enable service: # update-rc.d glusterfs-server defaults
# sudo apt-get install glusterfs-server attr start / enable service: # sudo systemctl start glusterfs-server.service # sudo systemctl enable glusterfs-server.service
# zypper install glusterfs start / enable service: # chkconfig glusterd on
MariaDB ColumnStore utilizes the System Logging applications for generating logs. So one of the below system logging applications should be install on all servers in the ColumnStore system:
Installing MariaDB ColumnStore with the use of soft-links. If you want to setup an install where the Data is stored out in a separate directory in the case you have limit amount local storage, this can be done. It is requied that the softlinks be setup at the Data Directory Levels, like mariadb/columnstore/data and mariadb/columnstore/dataX. With this setup, you can perform upgrades using any of the package types, rpm, debian, or binary. Dont set a softlink at the top directory, like /usr/local/mariadb or /usr/local/mariadb/columnstore.
IMPORTANT: Make sure there are no other version of MariaDB server install. If so, these will need to be uninstalled before installing MariaDB ColumnStore.
The default MariaDB ColumnStore installation process supports a Distributed installation functionality for Multi-Node installs. With Distributed,the MariaDB ColumnStore packages only needed to be installed on the Performance Module #1 node. MariaDB ColumnStore would distributed the packages across to the other nodes in the system and will install them automatically.
In the 1.1 version and later, MariaDB ColumnStore supports a Non-Distributed option for Multi-Node installs. With this option, the user is required to install the MariaDB ColumnStore on all the nodes in the system.
The MariaDB ColumnStore RPM and DEB Packages can be installed using yum/apt-get commands. Check here for additional Information:
The MariaDB ColumnStore RPM, DEB and binary Packages can be installed along with all of the other packages that make up the AX package. Check here for additional Information:
Note: MariaDB ColumnStore installation will install with a single MariaDB userid of root with no password. You may setup users and permissions for a MariaDB ColumnStore-Mysql account just as you would in MySQL.
Note: The packages will be installed into /usr/local. This is required for root user installs
Download the package mariadb-columnstore-release#.x86_64.tar.gz (RHEL5 64-BIT) to the server where you are installing MariaDB ColumnStore and place in the /root directory. Unpack the tarball, which will generate multiple RPMs that will reside in the /root/ directory.
tar -zxf mariadb-columnstore-release#.x86_64.tar
Install the RPMs. The MariaDB ColumnStore software will be installed in /usr/local/.
rpm -ivh mariadb-columnstore*release#*.rpm
The MariaDB ColumnStore binary package can be installed from the MariaDB Downloads page. <CLICK> on the "all versions" link and then step down into the OS version to the bottom level directory where you will see 2 packages, one for rpm/deb and the bother for the binary. Select the binary package to download.
Install MariaDB ColumnStore as user root on the server designated as PM1: Note: You may setup users and permissions for an MariaDB ColumnStore account just as you would in MariaDB.
For root user installs, MariaDB Columnstore needs to run in /usr/local. You can either install directly into /usr/local or install elsewhere and then setup a softlink to /usr/local. Here is an example of setting up a soft-link if you install the binary package in /mnt/mariadb
# ln -s /mnt/mariadb /usr/local
cp /root/mariadb-columnstore-release#.x86_64.bin.tar.gz /usr/local/ mariadb-columnstore-release#.x86_64.bin.tar.gz
tar -zxvf mariadb-columnstore-release#.x86_64.bin.tar.gz
Run the post-install script:
DEB package installs are not supported in the current version, but there is an Ubuntu 16.04 binary package that you can use to install. Just follow the binary package instructions above
Install MariaDB ColumnStore on a Debian or Ubuntu OS as user root: Note: You may setup users and permissions for an MariaDB ColumnStore account just as you would in MariaDB.
tar -zxf mariadb-columnstore-release#.amd64.deb.tar.gz
dpkg -i mariadb-columnstore*release#*.deb
MariaDB Columnstore can be installed to run as a non-root user using the binary tar file installation. These procedures will also allow you to change the installation from the default install directory into a user-specified directory. These procedures will need to be run on all the MariaDB ColumnStore Servers.
Non-root user, since the MariaDB Server runs under the user mysql, you can also install the MariaDB ColumnStore package and run as the mysql user. So below where it shows 'guest' as the user, you can substitute 'mysql'.
For the purpose of these instructions, the following assumptions are:
Before beginning the binary tar file installation you will need your system administrator to set up accounts for you on every MariaDB Columnstore node. The account name must be the same on every node. The password used must be the same on every node. If you subsequently change the password on one node, you must change it on every node. The user-id must be the same on every node as well. In the examples below we will use the account name 'guest' and the password 'mariadb'. Additionally, every node must have a basic Linux server package setup and additionally have expect (and all its dependencies) installed.
Group ID is an example, can be different than 1000, but needs to be the same on all servers in the cluster
adduser guest -u 1000
addgroup guest moduser -g guest guest
The value for user-id must be the same for all nodes.
su - guest
export COLUMNSTORE_INSTALL_DIR=$HOME/mariadb/columnstore export PATH=$COLUMNSTORE_INSTALL_DIR/bin:$COLUMNSTORE_INSTALL_DIR/mysql/bin:/usr/sbin:$PATH export LD_LIBRARY_PATH=$COLUMNSTORE_INSTALL_DIR/lib:$COLUMNSTORE_INSTALL_DIR/mysql/lib
The sudo configuration file on each node will need to be modified to add in the non-root user. The recommended way is to use the Unix command, visudo. The following example will add the ‘guest’ user: visudo
guest ALL=(ALL) NOPASSWD: ALL
ColumnStore needs the open file limit to be increased for the specified user. To do this edit the /etc/security/limits.conf file and make the following additions at the end of the file:
guest hard nofile 65536 guest soft nofile 65536
If you are already logged in as 'guest' you will need to log out and back in again for this change to take effect.
If you are using a SAN to store the database files, an ‘users‘ option will need to be added to the fstab entries (by the root user). For more information, please see the “SAN Mounted Database Files” section earlier in this guide.
/dev/sda1 /home/guest/mariadb/columnstore/data1 ext2 noatime,nodiratime,noauto,users 0 0
/dev/sdd1 /home/mariadb/columnstore/data2 ext2 noatime,nodiratime,noauto,users 0 0
The disk device being used will need to have its user permissions set to the non-root user name. This is an example command run as 'root' user setting the user ownership of dbroot /dev/sda1 to non-root user of 'guest':
mke2fs dbroot (i.e., /dev/sda1) mount /dev/sda1 /tmpdir chown -R infinidb.infinidb /tmpdir umount /tmpdir
If MariaDB Columnstore has ever before been installed on any of the planned hosts as a root user install, you must have the system administrator verify that no remnants of that installation exist. The non-root installation will not be successful if there are MariaDB Columnstore files owned by root on any of the hosts.
There should not be any files or directories owned by root in the /tmp directory
These directories are writing to by the MariaDB Columnstore applications and the permissions need to be set to allow them to create files. So the permissions of them need to be set to the following by root user.
chmod 777 /tmp chmod 777 /dev/shm
You should be familiar with the general MariaDB Columnstore installation instructions in this guide as you will be asked the same questions during installation.
If performing the MariaDB ColumnStore Multi-node Distributed Installation, the binary package only needs to be installed on Performance Module #1 (pm1). If performing Non-Distributed installs, the binary package is required to install the MariaDB ColumnStore on all the nodes in the system.
If performing the MariaDB ColumnStore Multi-node Distributed Installation, the post-install only needs to be run on Performance Module #1 (pm1). If performing Non-Distributed installs, the post-install needs to be run the MariaDB ColumnStore on all the nodes in the system.
export COLUMNSTORE_INSTALL_DIR=/home/guest/mariadb/columnstore export LD_LIBRARY_PATH=/home/guest/mariadb/columnstore/lib:/home/guest/mariadb/columnstore/mysql/lib /home/guest/mariadb/columnstore/bin/postConfigure -i /home/guest/mariadb/columnstore
If performing the MariaDB ColumnStore Multi-node Non-Distributed installs, the 'columnstore' service needs to be started on all the nodes in the system except Performance Module #1 (pm1). postConfigure is run from pm1, which is documented in the next section
Starting the 'columnstore' service:
Optional items to assist in MariaDB Columnstore auto-start and logging:
su - guest -l -c "/home/guest/mariadb/columnstore/bin/columnstore start"
sudo runuser -l mariadb-user -c "/home/mariadb-user/mariadb/columnstore/bin/columnstore start"
Note: Make sure the above entry is added to the rc.local file that gets executed at boot time. Depending on the OS installation, rc.local could be in a different location.
This tool can be running before doing installation on a single-server or multi-node installs. It will verify the setup of all servers that are going to be used in the Columnstore System.
The next step would be to run the install script postConfigure, check the Single Server Or Multi-Server Install guide.
MariaDB Columnstore System Configuration and Installation tool, 'postConfigure', will Configure the MariaDB Columnstore System and will perform a Package Installation of all of the Servers within the System that is being configured. It will prompt the user to configuration information like server, storage, MariaDB Server, and system features. It updates the MariaDB Columnstore System Configuration File, Columnstore.xml. At the end, it will start up the ColumnStore system.
NOTE: When prompted for password, enter the non-user account password OR just hit enter if you have setup the non-root user with password-less ssh keys on all nodes (Please see the “System Administration Information” section earlier in this guide for more information on ssh keys.)
This tool is always run on the Performance Module #1.
Example uses of this script are shown in the Single and Multi Server Installations Guides.
# /usr/local/mariadb/columnstore/bin/postConfigure -h This is the MariaDB ColumnStore System Configuration and Installation tool. It will Configure the MariaDB ColumnStore System based on Operator inputs and will perform a Package Installation of all of the Modules within the System that is being configured.
