Chapter 22. Databases

MariaDB-11.8.3

Introduction to MariaDB

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

[Note]

Note

Development versions of BLFS may not build or run some packages properly if LFS or dependencies have been updated since the most recent stable versions of the books.

Package Information

[Note]

Note

The installed size of MariaDB is 761 MB, but this can be reduced by about 268 MB, if desired, by removing the /usr/share/mariadb/test directory after installation.

[Caution]

Caution

If you are upgrading an existing database, please see the MariaDB Release Notes for additional information, and use the instructions after the Configuration Information section to ensure a safe upgrade.

Installation of MariaDB

[Warning]

Warning

MariaDB and MySQL cannot be installed on the same system without extensive changes to the build configuration of one of the two applications.

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 mariadb &&
useradd -c "MariaDB Server" -d /srv/mariadb -g mariadb -s /bin/false -u 40 mariadb

Fix an issue with detecting Boost-1.89.0 and later: 

sed -i 's/regex system/regex/' \
       storage/columnstore/columnstore/cmake/boost.cmake

Install MariaDB by running the following commands: 

mkdir build &&
cd    build &&

cmake -D CMAKE_BUILD_TYPE=Release                       \
      -D CMAKE_INSTALL_PREFIX=/usr                      \
      -D GRN_LOG_PATH=/var/log/groonga.log              \
      -D INSTALL_DOCDIR=share/doc/mariadb-11.8.3        \
      -D INSTALL_DOCREADMEDIR=share/doc/mariadb-11.8.3  \
      -D INSTALL_MANDIR=share/man                       \
      -D INSTALL_MYSQLSHAREDIR=share/mariadb            \
      -D INSTALL_MYSQLTESTDIR=share/mariadb/test        \
      -D INSTALL_PAMDIR=lib/security                    \
      -D INSTALL_PAMDATADIR=/etc/security               \
      -D INSTALL_PLUGINDIR=lib/mariadb/plugin           \
      -D INSTALL_SBINDIR=sbin                           \
      -D INSTALL_SCRIPTDIR=bin                          \
      -D INSTALL_SQLBENCHDIR=share/mariadb/bench        \
      -D INSTALL_SUPPORTFILESDIR=share/mariadb          \
      -D MYSQL_DATADIR=/srv/mariadb                     \
      -D MYSQL_UNIX_ADDR=/run/mariadb/mariadb.sock      \
      -D WITH_EXTRA_CHARSETS=complex                    \
      -D WITH_EMBEDDED_SERVER=ON                        \
      -D SKIP_TESTS=ON                                  \
      -D TOKUDB_OK=0                                    \
      -W no-dev                                         \
      .. &&
make

To test the results, issue: make test. Two tests, my_tzinfo and test-connect, are known to fail.

[Note]

Note

A more extensive set of tests can be run with the following: 

pushd mysql-test
./mtr --parallel <N> --mem --force
popd

Where N is the number of tests to run in parallel. Over 5400 tests are run in about 24 SBU with N=4. A few tests may fail, mainly due to character set issues.

Now, as the root user: 

make install

Command Explanations

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

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

-D SKIP_TESTS=ON: This switch disables tests for MariaDB Connector/C which are not supported without additional setup.

-D WITHOUT_SERVER=ON: Use this switch if you don't want the server and would like to build the client only.

-W no-dev: This switch turns off some warnings that are only useful for developers.

[Note]

Note

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

Configuring MariaDB

Config Files

/etc/mariadb/my.cnf and ~/.my.cnf

Configuration Information

Create a basic /etc/mariadb/my.cnf file using the following command as the root user: 

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

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

# The MySQL server
[mariadb]
port            = 3306
socket          = /run/mariadb/mariadb.sock
datadir         = /srv/mariadb
skip-external-locking
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.
skip-networking

# 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

# InnoDB tables are now used by default
innodb_data_home_dir = /srv/mariadb
innodb_log_group_home_dir = /srv/mariadb
# All the innodb_xxx values below are the default ones:
innodb_data_file_path = ibdata1:12M:autoextend
# You can set .._buffer_pool_size up to 50 - 80 %
# of RAM but beware of setting memory usage too high
innodb_buffer_pool_size = 128M
innodb_log_file_size = 48M
innodb_log_buffer_size = 16M
innodb_flush_log_at_trx_commit = 1
innodb_lock_wait_timeout = 50

# End /etc/mariadb/my.cnf
EOF

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

mariadb-install-db --basedir=/usr --datadir=/srv/mariadb --user=mariadb &&
chown -R mariadb:mariadb /srv/mariadb

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

install -v -m755 -o mariadb -g mariadb -d /run/mariadb &&
mariadbd-safe --user=mariadb 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. 

mariadb-admin -u root password

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

mariadb-admin -p shutdown

Boot Script

Install the /etc/rc.d/init.d/mariadb init script included in the blfs-bootscripts-20250225 package as the root user to start the MariaDB server during system boot-up. 

make install-mariadb
[Note]

Note

If you have an existing database already and this installation of binaries was just an upgrade to a newer version, check the upstream documentation for upgrading. It is recommended to run: 

mariadb-upgrade
