nginx在绝大数的场景中我们使用其用于做web中间件或反向代理使用，但是nginx实际上也提供了正向代理的功能。下面我们来进行nginx正向代理配置操作，以便大家能够掌握nginx正向代理配置方法。
第一步：获取nginx正向代理模块
git clone
https://github.com/chobits/ngx_http_proxy_connect_module
第二步：下载nginx源码包
wget http://nginx.org/download/nginx-1.9.12.tar.gz
tar xf nginx-1.9.12.tar.gz
第三步：通过补丁方法把上述下载的正向代理模块导入到nginx模块存储目录
cd nginx-1.9.12/
patch -p1 <
/root/ngx_http_proxy_connect_module/patch/proxy_connect.patch
第四步：编译安装nginx
yum -y install openssl-devel zlib-devel prce-devel
./configure
--add-dynamic-module=/root/ngx_http_proxy_connect_module
make && make install
第五步：配置所允许通过代理主机的主机列表
cat /usr/local/nginx/conf/client-allow.conf
allow 127.0.0.1;
allow 192.168.216.1;
allow 192.168.216.185;
第六步：修改nginx配置文件
cat /usr/local/nginx/conf/nginx.conf
user nobody;
worker_processes 1;
error_log logs/error.log;
error_log logs/error.log notice;
error_log logs/error.log info;
pid logs/nginx.pid;
load_module /usr/local/nginx/modules/ngx_http_proxy_connect_module.so; #位置注意
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log logs/access.log main;
sendfile on;
tcp_nopush on;
keepalive_timeout 0;
keepalive_timeout 65;
gzip on;
server {
listen 8080; #代理端口
resolver 119.29.29.29; #域名解析服务器
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 $host;
}
include client-allow.conf; #主机白名单
deny all; #除了主机白名单中的主机，拒绝所有
error_page 404 /404.html;
redirect server error pages to the static page /50x.html
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
proxy the PHP scripts to Apache listening on 127.0.0.1:80
location ~ \.php$ {
proxy_pass http://127.0.0.1;
}
pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
location ~ \.php$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
include fastcgi_params;
}
deny access to .htaccess files, if Apache's document root
concurs with nginx's one
location ~ /\.ht {
deny all;
}
}
another virtual host using mix of IP-, name-, and port-based configuration
server {
listen 8000;
listen somename:8080;
server_name somename alias another.alias;
location / {
root html;
index index.html index.htm;
}
}
HTTPS server
server {
listen 443 ssl;
server_name localhost;
ssl_certificate cert.pem;
ssl_certificate_key cert.key;
ssl_session_cache shared:SSL:1m;
ssl_session_timeout 5m;
ssl_ciphers HIGH:!aNULL:!MD5;
ssl_prefer_server_ciphers on;
location / {
root html;
index index.html index.htm;
}
}
}
第七步：检查并启动nginx服务
/usr/local/nginx/sbin/nginx -t #检查配置文件
/usr/local/nginx/sbin/nginx # 启动服务
/usr/local/nginx/sbin/nginx -s stop #关闭
/usr/local/nginx/sbin/nginx -s reload #重启加载配置文件
ss -anput | grep ":8080" #检查端口
第八步：被代理主机配置
第九步：被代理主机验证nginx正向代理可用性
ss -anput | grep ":8080"
tcp LISTEN 0 128 *:8080 *:* users:(("nginx",pid=19515,fd=6),("nginx",pid=19514,fd=6))
tcp ESTAB 0 0 192.168.216.184:8080 192.168.216.185:35718 users:(("nginx",pid=19515,fd=11))
tcp ESTAB 0 0 192.168.216.184:8080 192.168.216.185:35712 users:(("nginx",pid=19515,fd=3))
