The Ultimate Guide to High Availability with MariaDB

mariadb-embedded

You are viewing an old version of this article. View the current version here.

mariadb-embedded is a mariadb client statically linked to libmariadbd, the embedded server.

Prior to MariaDB 10.5, the client was called mysql_embedded. It can still be accessed under this name, via a symlink in Linux, or an alternate binary in Windows.

Upon execution, an embedded MariaDB server is instantiated and you can execute statements just as you would using the normal mariadb client, using the same options.

Do not run mariadb-embedded using the same database as a running MariaDB server!

Examples

sudo mariadb-embedded -e 'select user, host, password from mysql.user where user="root"'
+------+-----------+-------------------------------------------+
| user | host      | password                                  |
+------+-----------+-------------------------------------------+
| root | localhost | *196BDEDE2AE4F84CA44C47D54D78478C7E2BD7B7 |
| root | db1       | *196BDEDE2AE4F84CA44C47D54D78478C7E2BD7B7 |
| root | 127.0.0.1 | *196BDEDE2AE4F84CA44C47D54D78478C7E2BD7B7 |
| root | ::1       | *196BDEDE2AE4F84CA44C47D54D78478C7E2BD7B7 |
+------+-----------+-------------------------------------------+

Sending options with --server-arg:

sudo mariadb-embedded --server-arg='--skip-innodb'
  --server-arg='--default-storage-engine=myisam' 
  --server-arg='--log-error=/tmp/mysql.err' 
  -e 'select user, host, password from mysql.user where user="root"'
+------+-----------+-------------------------------------------+
| user | host      | password                                  |
+------+-----------+-------------------------------------------+
| root | localhost | *196BDEDE2AE4F84CA44C47D54D78478C7E2BD7B7 |
| root | db1       | *196BDEDE2AE4F84CA44C47D54D78478C7E2BD7B7 |
