CentOS6.3 Add a detailed example of nginx system services

CentOS 6.3 adds example details of nginx system services

Preface:

Today the VIRTUAL machine is equipped with a server to sort out this nginx service

Pay attention to this symbol - see if there is any messy code after copying it. I have encountered this problem before, and it took me a long time to find it

Tip: Do not remove the comment at the top or you will not be able to register as a system service,

About: chkconfig: 2345 65 37

Online search summed up the following meaning:

2345 system environment for starting the service 65 is the priority of the load 37 is the closed priority

The values of 65 and 37 cannot be the same, nor can they conflict with the values of other services. I have never encountered this problem. If you find any problem, please modify it according to your own configuration

New file:

# vi /etc/init.d/nginx
