if u have rewrite module installed : check by  apachectl -M    or apache2ctl -M
then check if the .htaccess is enabled (by default default is disabled)
to enable it go /etc/httpd/conf/httpd.conf and change:
  <Directory />
    Options FollowSymLinks
    AllowOverride None         /* change None to All */

to

   <Directory />

systemctl start mysqld.service
systemctl stop mysqld.service
systemctl enable mysqld.service   Enable the service over reboots (which just sets up some symlinks in the relevant dirs). same as chkconfig mysqld on  

systemctl disable mysqld.service
systemctl status mysqld.service


If you want to use the service commands they should still work as well:
service mysqld start
