nginx starts, restarts, shuts down

1. Start

cd usr/local/nginx/<span>sbin
.</span>/nginx

2. Restart

Change the configuration and restart nginx

　Query nginx main process number

ps -ef | grep nginx

　 Stop gracefully kill -QUIT main process number

Quick stop kill -TERM main process number

Force stop kill -9 nginx

If nginx.conf is configured with the pid file path, if not, then In the logs directory

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

Four. Upgrade

　1. First replace the old program file with the new program

　2. Kill -USR2 old version program The main process number or process file name

　At this time, the old nginx main process will rename its process file to .oldbin, and then execute the new version of nginx. At this time, the new and old versions will run at the same time

　　3. Kill -WINCH the old version of the main process No.

　　4. Start the new/old worker process without reloading the configuration

　　kill -HUP Old/new version main process number

　　Close the old/new process gracefully

　　kill -QUIT Old/new process number

　　Quickly close the old /New process

　　kill -TERM old/new process number

The above introduces the startup, restart, and shutdown of nginx, including the relevant content. I hope it will be helpful to friends who are interested in PHP tutorials.
