title: CentOS 7 : MariaDB service: Fails to start
body: <p>MariaDB service is not starting, mariadb.service file was created by the system. Status check shows the below error. We have provided 777 permission for the library but still the service throws this error. The DB Server (5.5.65) runs fine when we run mysqld_safe directly.</p>
  <pre><code>mariadb-prepare-db-dir[22847]: sed: error while loading shared libraries: libpcre.so.1: cannot open shared object file: Permission denied
  </code></pre>
  <p>Please let us know what might be wrong. Appreciate your help.</p>
