前言
Nginx是一种高性能的Web服务器软件。它是一个比Apache HTTP服务器更灵活和轻量级的程序。安装操作要求用户具有root权限
操作
1. 添加CentOS 7 EPEL 仓库
sudo yum install epel-release
2. 安装Nginx
sudo yum install nginx
3. 启动Nginx
sudo systemctl start nginx
4. 测试nginx服务：
wget http://127.0.0.1
若结果如下，说明nginx服务正常。
[root@hostname ~]# wget http://127.0.0.1
--2017-05-11 20:32:34-- http://127.0.0.1/
Connecting to 127.0.0.1:80... connected.
HTTP request sent, awaiting response... 200 OK
Length: 3700 (3.6K) [text/html]
Saving to: 'index.html'
100%[======================================>] 3,700 --.-K/s in 0s
2017-05-11 20:32:34 (632 MB/s) - 'index.html' saved [3700/3700]
5. 启动防火墙
sudo systemctl start firewalld.service
6. 允许HTTP和HTTPS传输
sudo firewall-cmd --permanent --zone=public --add-service=http
sudo firewall-cmd --permanent --zone=public --add-service=https
sudo firewall-cmd --reload
7. 在浏览器中输入服务器ip地址，看到类似 Welcome to nginx 字样，则表示安装成功
