MariaDB and MySQL have identical install methods. In this document we describe how to install MariaDB; However all documentation at www.mysql.com also applies. 2.2. Installing MariaDB from Generic Binaries on Unix/Linux This section covers the installation of MariaDB binary distributions that are provided for various platforms in the form of compressed tar files (files with a .tar.gz extension). MariaDB tar file binary distributions have names of the form mariadb-VERSION-OS.tar.gz, where VERSION is a number (for example, 5.1.39), and OS indicates the type of operating system for which the distribution is intended (for example, pc-linux-i686). You need the following tools to install a MariaDB tar file binary distribution: * GNU gunzip to uncompress the distribution. * A reasonable tar to unpack the distribution. GNU tar is known to work. Some operating systems come with a preinstalled version of tar that is known to have problems. For example, the tar provided with early versions of Mac OS X, SunOS 4.x, Solaris 8, Solaris 9, Solaris 10 and OpenSolaris, and HP-UX are known to have problems with long file names. On Mac OS X, you can use the preinstalled gnutar program. On Solaris 10 and OpenSolaris you can use the preinstalled gtar. On other systems with a deficient tar, you should install GNU tar first. If you run into problems and need to file a bug report, please report them to: http://mariadb.org/jira See the instructions in Section 1.6, "How to Report Bugs or Problems." The basic commands that you must execute to install and use a MariaDB binary distribution are: shell> groupadd mysql shell> useradd -g mysql mysql shell> cd /usr/local shell> gunzip < /path/to/mariadb-VERSION-OS.tar.gz | tar xvf - shell> ln -s full-path-to-mariadb-VERSION-OS mysql shell> cd mysql shell> chown -R mysql . shell> chgrp -R mysql . shell> scripts/mysql_install_db --user=mysql shell> chown -R root . shell> chown -R mysql data shell> bin/mysqld_safe --user=mysql & Note This procedure does not set up any passwords for MariaDB accounts. After following the procedure, proceed to Section 2.13, "Post-Installation Setup and Testing." A more detailed version of the preceding description for installing a binary distribution follows: 1. Add a login user and group for mysqld to run as: shell> groupadd mysql shell> useradd -g mysql mysql These commands add the mysql group and the mysql user. The syntax for useradd and groupadd may differ slightly on different versions of Unix, or they may have different names such as adduser and addgroup. You might want to call the user and group something else instead of mysql. If so, substitute the appropriate name in the following steps. 2. Pick the directory under which you want to unpack the distribution and change location into it. In the following example, we unpack the distribution under /usr/local. (The instructions, therefore, assume that you have permission to create files and directories in /usr/local. If that directory is protected, you must perform the installation as root.) shell> cd /usr/local 3. Obtain a distribution file using the instructions in Section 2.1.3, "How to Get MariaDB." For a given release, binary distributions for all platforms are built from the same MariaDB source distribution. 4. Unpack the distribution, which creates the installation directory. Then create a symbolic link to that directory: shell> gunzip < /path/to/mariadb-VERSION-OS.tar.gz | tar xvf - shell> ln -s full-path-to-mariadb-VERSION-OS mysql The tar command creates a directory named mariadb-VERSION-OS. The ln command makes a symbolic link to that directory. This lets you refer more easily to the installation directory as /usr/local/mysql. With GNU tar, no separate invocation of gunzip is necessary. You can replace the first line with the following alternative command to uncompress and extract the distribution: shell> tar zxvf /path/to/mariadb-VERSION-OS.tar.gz 5. Change location into the installation directory: shell> cd mysql You will find several files and subdirectories in the mysql directory. The most important for installation purposes are the bin and scripts subdirectories: + The bin directory contains client programs and the server. You should add the full path name of this directory to your PATH environment variable so that your shell finds the MariaDB programs properly. See Section 2.14, "Environment Variables." + The scripts directory contains the mysql_install_db script used to initialize the mysql database containing the grant tables that store the server access permissions. 6. Ensure that the distribution contents are accessible to mysql. If you unpacked the distribution as mysql, no further action is required. If you unpacked the distribution as root, its contents will be owned by root. Change its ownership to mysql by executing the following commands as root in the installation directory: shell> chown -R mysql . shell> chgrp -R mysql . The first command changes the owner attribute of the files to the mysql user. The second changes the group attribute to the mysql group. 7. If you have not installed MariaDB before, you must create the MariaDB data directory and initialize the grant tables: shell> scripts/mysql_install_db --user=mysql If you run the command as root, include the --user option as shown. If you run the command while logged in as that user, you can omit the --user option. The command should create the data directory and its contents with mysql as the owner. After creating or updating the grant tables, you need to restart the server manually. 8. Most of the MariaDB installation can be owned by root if you like. The exception is that the data directory must be owned by mysql. To accomplish this, run the following commands as root in the installation directory: shell> chown -R root . shell> chown -R mysql data 9. If you want MariaDB to start automatically when you boot your machine, you can copy support-files/mysql.server to the location where your system has its startup files. More information can be found in the support-files/mysql.server script itself and in Section 2.13.1.2, "Starting and Stopping MariaDB Automatically." 10. You can set up new accounts using the bin/mysql_setpermission script if you install the DBI and DBD::mysql Perl modules. See Section 4.6.14, "mysql_setpermission --- Interactively Set Permissions in Grant Tables." For Perl module installation instructions, see Section 2.15, "Perl Installation Notes." 11. If you would like to use mysqlaccess and have the MariaDB distribution in some nonstandard location, you must change the location where mysqlaccess expects to find the mysql client. Edit the bin/mysqlaccess script at approximately line 18. Search for a line that looks like this: $MYSQL = '/usr/local/bin/mysql'; # path to mysql executable Change the path to reflect the location where mysql actually is stored on your system. If you do not do this, a Broken pipe error will occur when you run mysqlaccess. After everything has been unpacked and installed, you should test your distribution. To start the MariaDB server, use the following command: shell> bin/mysqld_safe --user=mysql & If you run the command as root, you must use the --user option as shown. The value of the option is the name of the login account that you created in the first step to use for running the server. If you run the command while logged in as mysql, you can omit the --user option. If the command fails immediately and prints mysqld ended, you can find some information in the host_name.err file in the data directory. More information about mysqld_safe is given in Section 4.3.2, "mysqld_safe --- MySQL Server Startup Script." Note The accounts that are listed in the MariaDB grant tables initially have no passwords. After starting the server, you should set up passwords for them using the instructions in Section 2.13, "Post-Installation Setup and Testing."
