MySQL fails to start. While attempt to start MySQL the following error appears in the /var/log/mysqld.log or in /var/log/mariadb/mariadb.log:

    [ERROR] /usr/libexec/mysqld: unknown variable 'set-variable=local-infile=0'
    [ERROR] Aborting

or the following one:

    [ERROR] /usr/libexec/mysqld: unknown variable 'max_allowed_packed=128M'
    [ERROR] Aborting


  1. File /etc/my.cnf has set-variable=local-infile=0 in it and MySQL version does not support that parameter.

  2. Misprint in variable name.

but this option is deprecated in MySQL v 5.5.


  1. Check that variable name is set correctly.

  2. Comment line set-variable=local-infile=0 in /etc/my.cnf file.

  3. Start Mysql service:

    /etc/init.d/mysql start
