CentOS under Nginx startup script and Chkconfig management

After installing Nginx, restarting requires "kill-hup Nginx process number" to reload, obviously very inconvenient. It's much easier to manage it directly from a script, just like Apache.

Nginx official long thought, also provided this script, address: Http://wiki.nginx.org/RedHatNginxInitScript. Here are the management scripts that are included here:

Save the above script to the/etc/init.d/nginx file and modify the two places:

• nginx= "/usr/sbin/nginx" to modify the path of the Nginx execution program.
• Nginx_conf_file= "/etc/nginx/nginx.conf" is modified to the path of the configuration file.

Once saved, the Nginx service can be managed by this script:

$/etc/init.d/nginx start$/etc/init.d/nginx stop$/etc/init.d/nginx Reload ...

Using Chkconfig for Management

The above method has completed the function of using script to manage Nginx service, but it is still not very convenient, such as setting nginx boot up and so on. You can use Chkconfig to set this.

Add Nginx service to Chkconfig management list first:

Chkconfig--add/etc/init.d/nginx

After adding this, you can use the service to start, restart, and so on Nginx operation.

$ service Nginx start$ service nginx stop$ service Nginx Reload ...

Set up terminal mode boot:
