最近我的多个VPS经常出现502错误,经常需要重启nginx,但网上的很多教程都需要繁琐的启动脚本,远不如apache的重启命令那么简单。
但研究了一下nginx帮助后发现,有-s参数可对nginx服务进行管理:
# /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
于是我执行
# /usr/local/nginx/sbin/nginx -s reload
nginx已经重启成功
