nginx官网安装教程：http://nginx.org/en/linux_packages.html#RHEL-CentOS
一、安装
1.安装准备
sudo yum install yum-utils
2.增加源文件
vim /etc/yum.repos.d/nginx.repo
内容为：
[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
3.安装
sudo yum install nginx
4.查看安装版本
rpm -qa | grep nginx
5.启动nginx
systemctl start nginx
若报错
可能80端口被占用
netstat -apn|grep :80
关闭80端口
service httpd stop
再次重新启动，无报错则启动成功
6.查看启动状态
systemctl status nginx
7.设置开机自启动
systemctl enable nginx
到此安装成功！
