Introduction to MariaDB

MariaDB is a community-developed fork and a drop-in replacement for the MySQL relational database management system.

This package is known to build and work properly using an LFS-7.5 platform.

User Notes:

Installation of MariaDB



This version of MariaDB is a development release. The BLFS staff has determined that it provides a stable program and includes backported features from MySQL 5.6 and entirely new features not found anywhere else. To find the current stable release, please refer to the MariaDB home page.

For security reasons, running the server as an unprivileged user and group is strongly encouraged. Issue the following (as root) to create the user and group:

groupadd -g 40 mysql &&
useradd -c "MySQL Server" -d /srv/mysql -g mysql -s /bin/false -u 40 mysql

Install MariaDB by running the following commands:

sed -i "s@data/test@\${INSTALL_MYSQLTESTDIR}@g" sql/CMakeLists.txt &&
sed -i "s/srv_buf_size/srv_sort_buf_size/" storage/innobase/row/ &&
mkdir build &&
cd build &&
cmake -DCMAKE_BUILD_TYPE=Release \
      -DINSTALL_DOCDIR=share/doc/mysql \
      -DINSTALL_DOCREADMEDIR=share/doc/mysql \
      -DINSTALL_MANDIR=share/man \
      -DINSTALL_MYSQLSHAREDIR=share/mysql \
      -DINSTALL_MYSQLTESTDIR=share/mysql/test \
      -DINSTALL_PLUGINDIR=lib/mysql/plugin \
      -DINSTALL_SBINDIR=sbin \
      -DINSTALL_SQLBENCHDIR=share/mysql/bench \
      -DMYSQL_DATADIR=/srv/mysql \
      -DMYSQL_UNIX_ADDR=/run/mysqld/mysqld.sock \
      -DWITH_EXTRA_CHARSETS=complex \
      -DTOKUDB_OK=0 \
      .. &&

To test the results, issue: make test.

Now, as the root user:

make install

Command Explanations

sed -i ...: First sed sets correct installation directory for some components. Second sed fixes a bug in the code.

-DWITH_EXTRA_CHARSETS=complex: This switch enables support for the complex character sets.

-DWITHOUT_SERVER=ON -DWITH_UNIT_TESTS=OFF: Use these switches if you don't want the server and would like to build the client only.

-DWITH_EMBEDDED_SERVER=ON: This switch enables compiling the embedded server library needed by certain applications, such as Amarok.



There are numerous options available to cmake. Check the output of the cmake . -LH for additional customization options.

Configuring MySQL

Config Files

/etc/mysql/my.cnf and ~/.my.cnf

Configuration Information

Create basic /etc/mysql/my.cnf using the following command as the root user:

install -v -dm 755 /etc/mysql &&
cat > /etc/mysql/my.cnf << "EOF"
# Begin /etc/mysql/my.cnf

# The following options will be passed to all MySQL clients
#password       = your_password
port            = 3306
socket          = /run/mysqld/mysqld.sock

# The MySQL server
port            = 3306
socket          = /run/mysqld/mysqld.sock
datadir         = /srv/mysql
key_buffer_size = 16M
max_allowed_packet = 1M
sort_buffer_size = 512K
net_buffer_length = 16K
myisam_sort_buffer_size = 8M

# Don't listen on a TCP/IP port at all.

# required unique id between 1 and 2^32 - 1
server-id       = 1

# Uncomment the following if you are using BDB tables
#bdb_cache_size = 4M
#bdb_max_lock = 10000

# Uncomment the following if you are using InnoDB tables
#innodb_data_home_dir = /srv/mysql
#innodb_data_file_path = ibdata1:10M:autoextend
#innodb_log_group_home_dir = /srv/mysql
# You can set .._buffer_pool_size up to 50 - 80 %
# of RAM but beware of setting memory usage too high
#innodb_buffer_pool_size = 16M
#innodb_additional_mem_pool_size = 2M
# Set .._log_file_size to 25 % of buffer pool size
#innodb_log_file_size = 5M
#innodb_log_buffer_size = 8M
#innodb_flush_log_at_trx_commit = 1
#innodb_lock_wait_timeout = 50

max_allowed_packet = 16M

# Remove the next comment character if you are not familiar with SQL

key_buffer = 20M
sort_buffer_size = 20M
read_buffer = 2M
write_buffer = 2M

key_buffer_size = 20M
sort_buffer_size = 20M
read_buffer = 2M
write_buffer = 2M


# End /etc/mysql/my.cnf

You can now install a database and change the ownership to the unprivileged user and group (perform as the root user):

mysql_install_db --basedir=/usr --datadir=/srv/mysql --user=mysql &&
chown -R mysql:mysql /srv/mysql

Further configuration requires that the MariaDB server is running. Start the server using the following commands as the root user:

install -v -m755 -o mysql -g mysql -d /run/mysqld &&
mysqld_safe --user=mysql 2>&1 >/dev/null &

A default installation does not set up a password for the administrator, so use the following command as the root user to set one. Replace <new-password> with your own.

mysqladmin -u root password <new-password>

Configuration of the server is now finished. Shut the server down using the following command as the root user:

mysqladmin -p shutdown

Boot Script

Install the /etc/rc.d/init.d/mysql init script included in the blfs-bootscripts-20140301 package as the root user to start the MariaDB server during system boot-up.

make install-mysql

Short Descriptions

Descriptions of all the programs and libraries would be several pages long. Instead, consult the man pages or the online documentation at

The Perl DBI modules must be installed for some of the MariaDB support programs to function properly.
