CentOS7安装Nginx

一、配置Yum源

[root@test1 ~]# sudo yum install yum-utils
[root@test1 ~]# vi /etc/yum.repos.d/nginx.repo
[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
module_hotfixes=true

[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
module_hotfixes=true

//如果想使用主线版本可以运行sudo yum-config-manager --enable nginx-mainline
[root@test1 ~]# sudo yum install nginx      //这里默认采用nginx-stable稳定版本

二、配置优化

以下配置文件仅供参考

[root@test1 ~]# cat /etc/nginx/nginx.conf |egrep -v "#|^"
