I am on Centos 7 , with default installation of MySql 5.7 . I followed the instructions in this article to parallelly install latest GA version 10.1.16 of MariaDB , but while attemtping to start MariaDb , it fails .
i.e. when I give the below command in the shell
/etc/init.d/mariadb start
The following is indicated in the localhost.localdomain.err
[root@localhost opt]# cat mariab-data/localhost.localdomain.err cat: mariab-data/localhost.localdomain.err: No such file or directory [root@localhost opt]# cat mariadb-data/localhost.localdomain.err 160726 18:24:42 mysqld_safe A mysqld process already exists 160726 18:26:00 mysqld_safe Fatal error: Can't remove the pid file: /var/run/mysqld/mysqld.pid Please remove it manually and start /opt/mariadb/bin/mysqld_safe again; mysqld daemon not started
How do I solve this problem? thanks Taha
solved it by setting the macro in /etc/init.d/mariadb at line 284 , as it is being evaluated to the one used by MySql instance.
mysqld_pid_file_path=$datadir/`hostname`.pid
Other than this the instructions on this webpage work like a charm ! thanks Taha
