Force stop Nginx:

kill -9 主进程号

In addition, if the pid file storage path is configured in nginx.conf, the file will be stored in Nginx The main process number. If not specified, it will be placed in the logs directory of nginx. With the pid file, we don't need to query the main process number of Nginx first, but directly send the signal to Nginx. The command is as follows:

kill -Signal type'/usr/local/nginx/logs/nginx.pid '

Smooth restart

If you change the configuration, you need to restart Nginx. Do you need to close Nginx first and then open it? No, you can send a signal to Nginx to restart smoothly.

Smooth restart command:

kill -HUP 住进称号或进程号文件路径 或者使用/usr/nginx/sbin/nginx -s reload

Note that after modifying the configuration file, it is best to check whether the modified configuration file is correct to avoid Nginx errors after restarting. The server runs stably. The command to determine whether Nginx configuration is correct is as follows:

nginx -t -c /usr/nginx/conf/nginx.conf 或者/usr/nginx/sbin/nginx -t
