How to set Apache start at boot time on Linux

If you feel lazy to restart the httpd service everytime your machine boot up, just do following simple steps:

1. Enter below command to show the runlevel information of the httpd service
   chkconfig –list | grep httpd
   
2. You get something like this:
   httpd 0:off 1:off 2:off 3:off 4:off 5:off 6:off
   
3. Then, set up httpd to start at boot time.
   chkconfig httpd on
   
4. Now to can verify by reviewing the runlevel information of the httpd service
   chkconfig –list | grep httpd
   
5. Output should be.
   httpd 0:off 1:off 2:on 3:on 4:on 5:on 6:off
   
6. You’ve done !

If you just want to enable the servive for a certain runlevel (e.g. graphic mode or non graphic mode), you can use below command instead where 3 indicates the runlevel.

• chkconfig –level 3 httpd

This method can be applied to enable/disable other services at boot time. So, to list available services on your machine, run the command:

• chkconfig –list
