nginx 常用命令
start nginx 启动nginx
nginx -s stop 快速关闭Nginx,可能不保存相关信息,并迅速终止web服务。
nginx -s quit 平稳关闭Nginx,保存相关信息,有安排的结束web服务。
nginx -s reload 因改变了Nginx相关配置,需要重新加载配置而重载。
nginx -s reopen 重新打开日志文件。
nginx -c filename 为 Nginx 指定一个配置文件,来代替缺省的。
nginx -t 不运行,而仅仅测试配置文件。nginx 将检查配置文件的语法的正确性,并尝试打开配置文件中所引用到的文件。
nginx -v 显示 nginx 的版本。
nginx -V 显示 nginx 的版本,编译器版本和配置参数
常用命令
(1) 启动:./nginx
(2) 测试Nginx配置是否正确:./nginx -t
(3) 优雅重启:./nginx -s reload
(4) 查看nginx的进程号:ps -ef | grep nginx
(5)nginx服务停止./nginx -s stop
kill -9 pid 杀死进程,一般情况下禁止使用此种方法。可能会导致主进程被杀死,workpress依然存在的情况。可以使用kill -15 pid
。
nginx默认路径
(1) Nginx配置路径:/etc/nginx/
(2) PID目录:/var/run/[nginx.pid](https://www.centos.bz/tag/nginx-pid/)
(3) 错误日志:/var/log/nginx/[error](https://www.centos.bz/tag/error/).log
(4) 访问日志:/var/log/nginx/access.log
(5) 默认站点目录:/usr/share/nginx/html
事实上,只需知道Nginx配置路径,其他路径均可在/etc/nginx/nginx.conf 以及/etc/nginx/conf.d/default.conf 中查询
到。
