Centos7安装nginx

1.安装nginx服务，首先在nginx官网找到yum源，根据自己操作系统版本找到对应的源：

Index of /packages/centos/7/x86_64/

2.创建nginx 的yum源仓库：vim /etc/yum.repos.d/nginx.repo

[nginx-stable]
name=nginx stable repo
baseurl=http://nginx.org/packages/centos/7/x86_64/
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/7/x86_64/
gpgcheck=1
enabled=0
gpgkey=https://nginx.org/keys/nginx_signing.key

3.执行命令： yum repolist

4.安装nginx:  yum install -y nginx

5. 启动Nginx服务，并设置Nginx开机自启:

        systemctl start nginx

        systemctl enable nginx

6.关闭防火墙或者开放http:

        systemctl stop firewalld 

        或者

        firewall-cmd --permanent --add-service=http

        firewall-cmd --reload

7.界面访问：IP地址

到此nginx搭建完成。
