title: How to start mysql service without systemctl/service tool
body: <p>Mysql service is running on centos system. Recently we had a planned power outage so we shut down the mysql services.
  I am bringing back the service now. I wish to run mysqld_safe as mysql user and not to start as root and not to use systemctl/service.</p>
  
  <p>The only method I know is: </p>
  
  <p>sudo systemctl mysql restart</p>
  
  <p>sudo service mysql start</p>
  
  <p>Anyone have any inputs on how I can start mysql service as mysql user without using systemctl/service tool.</p>
  
  <p>I tried this in /usr/bin
   <code>mysqld_safe -user=mysql &amp;</code> and got permission denied error</p>
  
  <p>Thanks for you inputs in advance. </p>
