nginx服务常用操作

#查看nginx服务状态
systemctl status nginx.service
#启动nginx服务
systemctl start nginx.service
#停止nginx服务
systemctl stop nginx.service
#重启nginx服务
systemctl restart nginx.service
#重新读取nginx配置(这个最常用, 不用停止nginx服务就能使修改的配置生效)
systemctl reload nginx.service

启动nginx报错：Failed to start The nginx HTTP and reverse proxy server

对于报错的描述是Address already in use，说明端口被占用：
