简单记录在centos系统中，通过yum安装nginx并设置为开机自启动。

一、设置yum源

cd /etc/yum.repos.d/
vim nginx.repo

向nginx.repo中输入以下信息：

[nginx-stable]
name=nginx stable repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=1
enabled=1
gpgkey=https://nginx.org/keys/nginx_signing.key

[nginx-mainline]
name=nginx mainline repo
baseurl=http://nginx.org/packages/mainline/centos/$releasever/$basearch/
gpgcheck=1
enabled=0
gpgkey=https://nginx.org/keys/nginx_signing.key

二、yum安装nginx

yum install nginx

三、查看nginx是否安装成功

systemctl status nginx

四、设置为开机自启动

systemctl enable nginx
