Folks I'm having problems installing Mariadb in Centos 7. Here's what I did: 0) Become root 1) Make sure that mariadb and mysql are NOT installed. 2) Delete residual libs rm -rf /var/lib/mysq* 3) yum install -y mariadb-server installed mariadb-5.5.50-1.el7_2.x86_64 from the Centos 'updates' repository 4) systemctl start mariadb 5) systemctl status mariadb All works well until step 5, where I get the result: # systemctl status mariadb ? mariadb.service - MariaDB database server Loaded: loaded (/usr/lib/systemd/system/mariadb.service; enabled; vendor preset: disabled) Active: failed (Result: exit-code) since Thu 2016-09-22 17:46:38 PDT; 4min 3s ago Main PID: 16261 (code=exited, status=1/FAILURE) Sep 22 17:46:37 goat.xxx.com mysqld_safe[16261]: /usr/bin/mysqld_safe: line 139: /var/log/mysqld.log: Permission denied Sep 22 17:46:37 goat.xxx.com mysqld_safe[16261]: /usr/bin/mysqld_safe: line 183: /var/log/mysqld.log: Permission denied Sep 22 17:46:37 goat.xxx.com mysqld_safe[16261]: touch: cannot touch `/var/log/mysqld.log': Permission denied Sep 22 17:46:37 goat.xxx.com mysqld_safe[16261]: chown: cannot access `/var/log/mysqld.log': No such file or directory Sep 22 17:46:37 goat.xxx.com mysqld_safe[16261]: chmod: cannot access `/var/log/mysqld.log': No such file or directory Sep 22 17:46:37 goat.xxx.com systemd[1]: mariadb.service: main process exited, code=exited, status=1/FAILURE Sep 22 17:46:38 goat.xxx.com systemd[1]: mariadb.service: control process exited, code=exited status=1 Sep 22 17:46:38 goat.xxx.com systemd[1]: Failed to start MariaDB database server.

Hint: Some lines were ellipsized, use -l to show in full. [root at goat ~]# My environment is a Centos 7 installation running as a VM inside Vmware, and is not a production system. It is updated nightly. When I examined the files alluded to, /var/log/mysqld.log does not exist but /var/log/mariadb/mariadb.log exists and is empty. Adivce would be appreciated Thanks David
