Linux 安装nginx

1、安装nginx

sudo yum install nginx
在这里插入图片描述

2、安装好的位置：

/usr/sbin/nginx：主程序

/etc/nginx：存放配置文件

/usr/share/nginx：存放静态文件

/var/log/nginx：存放日志

3、启动并验证效果

service nginx start #启动nginx

service nginx reload #重新加载nginx配置文件

nginx -s reopen # 重启 Nginx

nginx -s stop # 停止 Nginx

nginx -v
在这里插入图片描述
报错：Redirecting to /bin/systemctl reload nginx.service
错误原因：service nginx start 是centos6.x的命令， centos7.x使用 systemctl start nginx
正确命令：/bin/systemctl reload nginx.service
