mysql_embedded

mysql_embedded is a mysql client statically linked to libmysqld, the embedded server. Upon execution, an embedded MariaDB server is instantiated and you can execute statements just as you would using the normal mysql client, using the same options.

From MariaDB 10.4.6, mariadb-embedded is a symlink to mysql_embedded.

Do not run mysql_embedded while MariaDB is running, as effectively it starts a new instance of the server.

Examples

sudo mysql_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 mysql_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 |
| root | 127.0.0.1 | *196BDEDE2AE4F84CA44C47D54D78478C7E2BD7B7 |
| root | ::1       | *196BDEDE2AE4F84CA44C47D54D78478C7E2BD7B7 |
