centos安装nginx

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; } } ...
