nginx重啟命令
最近我的多個VPS經常出現502錯誤，經常需要重啟nginx，但網上的很多教程都需要繁瑣的啟動腳本，遠不如apache的重啟命令那麼簡單。
但研究了一下nginx幫助後發現，有-s參數可對nginx服務進行管理：
# /usr/local/nginx/sbin/nginx -h
nginx version: nginx/0.7.63
Usage: nginx [-?hvVt] [-s signal] [-c filename] [-p prefix] [-g directives]
Options:
-?,-h : this help
-v : show version and exit
-V : show version and configure options then exit
-t : test configuration and exit
-s signal : send signal to a master process: stop, quit, reopen, reload
-p prefix : set prefix path (default: /usr/local/nginx/)
-c filename : set configuration file (default: conf/nginx.conf)
-g directives : set global directives out of configuration file
於是我執行
# /usr/local/nginx/sbin/nginx -s reload
nginx已經重啟成功
