cd /usr/local/nginx/
#gzip on;下添加
vim conf/nginx.conf
#gzip on;
#正向代理转发http请求
server {
#指定DNS服务器IP地址
resolver 114.114.114.114;
#监听80端口，http默认端口80
listen 80;
#服务器IP或域名
server_name localhost;
#正向代理转发http请求
location / {
proxy_pass http://$host$request_uri;
proxy_set_header HOST $host;
proxy_buffers 256 4k;
proxy_max_temp_file_size 0k;
proxy_connect_timeout 30;
proxy_send_timeout 60;
proxy_read_timeout 60;
proxy_next_upstream error timeout invalid_header http_502;
#正向代理转发https请求
server {
#指定DNS服务器IP地址
resolver 114.114.114.114;
#监听443端口，https默认端口443
listen 443;
#正向代理转发https请求
proxy_connect;
proxy_connect_allow 443 563;
proxy_connect_connect_timeout 10s;
proxy_connect_read_timeout 10s;
proxy_connect_send_timeout 10s;
location / {
proxy_pass http://$host;
proxy_set_header Host $host;
创建nginx用户
nginx服务以用户nginx身份启动
检查nginx配置并启动
ss -utnlp | grep nginx
tcp LISTEN 0 511 *:443 *:* users:(("nginx",pid=6645,fd=7),("nginx",pid=6644,fd=7))
tcp LISTEN 0 511 *:80 *:* users:(("nginx",pid=6645,fd=6),("nginx",pid=6644,fd=6))nginx服务所在服务器验证正向代理功能

配置不能访问外网的服务器（即内网服务器）,使其可以访问外网
liunx服务器配置
1.只配置使用yum时，能够使用正向代理访问外网
#追加配置
vim /etc/yum.conf
proxy=http://192.168.0.20:80 #nginx正向代理服务器的地址
proxy=ftp://192.168.0.20:80 #nginx正向代理服务器的地址
2.只配置使用wget时，能够使用正向代理访问外网
#追加配置
vim /etc/wgetrc
http_proxy=192.168.0.20:80 #nginx正向代理服务器的地址
http_proxy=192.168.0.20:443 #nginx正向代理服务器的地址
3.全局配置，所以访问请求都能够使用正向代理访问外网
#追加配置
vim /etc/profile
http_proxy=192.168.0.20:80
https_proxy=192.168.0.20:443
ftp_proxy=192.168.0.20:443
export http_proxy
export https_proxy
export ftp_proxy
# 加载配置
source /etc/profile
windows服务器配置
验证不能访问外网的服务器（即内网服务器）,使用代理上网
