Nginx的信号控制
| TERM, INT | Quick shutdown |
| QUIT | Graceful shutdown 优雅的关闭进程,即等请求结束后再关闭 |
| HUP | Configuration reload ,Start the new worker processes with a new configuration Gracefully shutdown the old worker processes 改变配置文件,平滑的重读配置文件 |
| USR1 | Reopen the log files 重读日志,在日志按月/日分割时有用 |
| USR2 | Upgrade Executable on the fly 平滑的升级 |
| WINCH | Gracefully shutdown the worker processes 优雅关闭旧的进程(配合USR2来进行升级) |
具体语法:
Kill -信号选项 nginx的主进程号
Kill -HUP 4873
Kill -信号控制 cat /xxx/path/log/nginx.pid
Kil; -USR1 cat /xxx/path/log/nginx.pid
