Create nginx scripts in Linux-start, stop, reload ..., Nginx-start

Create nginx scripts in Linux-start, stop, reload ..., Nginx-start

1. Disable nginx
Use ps-aux | grep nginx to check whether nginx is started. If so, kill and kill.
2. Create the/etc/init. d/nginx file.

root@dnnp:~/software/nginx-1.2.3# vim /etc/init.d/nginx

3. add permissions and start

root@dnnp:~/software/nginx-1.2.3# chmod +x /etc/init.d/nginxroot@dnnp:~/software/nginx-1.2.3# /etc/init.d/nginx startStarting nginx: nginx.root@dnnp:~/software/nginx-1.2.3# ps -aux | grep nginxWarning: bad ps syntax, perhaps a bogus '-'?

Note: The content of the/etc/init. d/nginx file is as follows:

How to restart nginx in linux

In earlier versions of nginx, the kill command is used to send a signal to nginx to restart nginx.
However, the-s option is added to nginx to stop and reload nginx.
1. For a smooth restart of nginx, you can use the./nginx-s reload command to achieve a smooth restart of nginx.
2. If it is not a smooth restart, you can stop nginx and then start it:
./Nginx-s stop &./nginx

After we modify the nginx configuration, we want to restart nginx to make nginx take effect. In this case, to ensure that nginx can provide normal services during the restart phase, we usually use a smooth restart (reload) method) restart nginx. In this case, nginx loads the new configuration and fork the new worker process. At the same time, the master process sends a signal to the old worker process to tell the current situation of the old worker process. After the old worker process receives the signal from the master process, if the request is not processed at the time, it will exit. If the request is being processed, the old worker process will finish processing the request and then exit. Nginx reload the new configuration in this way, so that the service can still be provided during the restart process.

Restart nginx. The command is displayed. Enter the following command:

Start service stop Service reload re-reading configuration restart service
