Going through some of the advanced commands, I kept running into compatibility issues between CentOS 6.x & CentOS 7. Although the differences were minor they did waste my time in configuring simple things like auto-starting applications and services. So here’s a list of commands that would benefit in administering application and services.
Auto Start Service on CentOS 6.x
$ sudo chkconfig --list httpd $ sudo chkconfig --add redis $ sudo chkconfig --add httpd $ sudo chkconfig redis on $ sudo chkconfig httpd on
Auto Start Service on CentOS 7.x
$ sudo systemctl status httpd $ sudo chkconfig enable redis $ sudo chkconfig enable httpd
