nginx正向代理和反向代理

一、正向代理 ①添加网卡（仅主机模式）

[root@host1 conf.d]# pwd/usr/local/nginx/conf.d

②配置

[root@host1 conf.d]# vim test1.conf

这里设置监听端口为8080

server { resolver 114.114.114.114; listen 8080; location / { proxy_pass http://$http_host$request_uri; }}

③重启nginx 二、反向代理（host1 host2 localhost 分别为三台linux虚拟机） #简单模拟

host2 和 localhost 安装httpd

①localhost配置

localhost 设置为仅主机模式添加ip 192.168.91.131

[root@localhost ~]# echo "this is a test" > /var/www/html/index.html[root@localhost ~]# systemctl start httpd[root@localhost ~]# systemctl stop firewalld[root@localhost ~]# setenforce 0

 ②host1 配置

这里设置监听端口为8800

[root@host1 conf.d]# vim test2.conf

server { listen 8800; server_name localhost; location /{ proxy_pass http://192.168.91.131; }}

如下：测试语法无误

 重启nginx

 ③使用一台不能ping通linux电脑curl

此台电脑需要关掉防火墙并设置selinux

curl 8800 端口

1、配置用于测试的两台Web服务器（host2、host3）

host2、host3为两台web服务器

均安装epel（rhel7）

wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

使用yum下载nginx

yum install nginx -y

mkdir /usr/share/nginx/html/{www,bbs}/logs -pcd /etc/nginx/conf.d

vim vhost.conf

server { listen 80; server_name bbs.yunjisuan.com; location / { root /usr/share/nginx/html/bbs; index index.html index.htm; } access_log /usr/share/nginx/html/bbs/logs/access_bbs.log main;}server { listen 80; server_name www.yunjisuan.com; location / { root /usr/share/nginx/html/www; index index.html index.htm; } access_log /usr/share/nginx/html/www/logs/access_www.log main;}

echo "`hostname -I `www" > /usr/share/nginx/html/www/index.htmlecho "`hostname -I `www" > /usr/share/nginx/html/bbs/index.html

2、host1、host2关掉防火墙，设置selinux

systemctl stop firewalldsetenforce 0

3、host1、host2开启nginx

systemctl start nginx检查语法nginx -t

4、重新找一台电脑curl
