一、在/etc/yum.repos.d/目录下创建一个源配置文件nginx.repo
vim /etc/yum.repos.d/nginx.repo
//创建内容
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=0
enabled=1
保存以后会在/etc/yum.repos.d/中创建nginx.repo文件
二、yum install nginx -y安装
yum install nginx -y
三、Nginx的命令以及配置文件位置
/etc/init.d/nginx start # 启动Nginx服务
/etc/init.d/nginx stop # 停止Nginx服务
/etc/nginx/nginx.conf # Nginx配置文件位置
chkconfig nginx on #设为开机启动
四、设置防火墙
//设置80端口白名单
iptables -I INPUT 5 -i eth0 -p tcp --dport 80 -m state --state NEW,ESTABLISHED -j ACCEPT
//保存
service iptables save
//重启防火墙
service iptables restart
五、配置Nginx文件
- 1、编辑/etc/nginx/nginx.conf
//在nginx.conf中,有一行代码,代表它去加载文件夹/conf.d/中的所有.conf文件
include /etc/nginx/conf.d/*.conf;
- 2、编辑/etc/nginx/conf.d文件
server {
listen 80;
server_name localhost;
#charset koi8-r;
#access_log /var/log/nginx/host.access.log main;
location / {
root /usr/share/nginx/html;
index index.html index.htm;
}
....
}
- 3、一台主机上适应多个服务器
http {
....
server {
listen 80;
server_name www.a.com;
charset utf-8;
access_log /home/a.com.access.log main;
location / {
proxy_pass http://127.0.0.1:80;
}
}
server {
listen 80;
server_name www.b.com;
charset utf-8;
access_log /home/b.com.access.log main;
location / {
proxy_pass http://127.0.0.1:81;
}
}
...
