正向代理

nginx

nginx: http://nginx.org/packages/centos/7/x86_64/RPMS/

在线安装

yum install nginx -y

常用命令

# 查看版本
nginx -V
# 启动命令
nginx
# 检查配置
nginx -t
# 重新加载配置
nginx -s reload
# 停止
nginx -s stop

离线安装

下载 rpm 包到 /opt 目录下，然后安装
nginx 依赖 libpcre2 ，还需要下载 libpcre2

rpm -ivh pcre2-10.23-2.el7.x86_64.rpm
rpm -ivh nginx-1.22.1-1.el7.ngx.x86_64.rpm

tengine

tengine: http://tengine.taobao.org/download.html

tengine 已经内置了 ngx_http_proxy_connect_module 模块，不需要从外部加载

# 如果安装了nginx，先卸载
rpm -qa|grep nginx
rpm -e nginx-1.20.2-1.el7.ngx.x86_64
# 编译安装
# 下载源码包到/opt 目录下
tar zxf tengine-2.3.3.tar.gz
cd tengine-2.3.3/
./configure --prefix=/opt/nginx --add-module=./modules/ngx_http_proxy_connect_module
make && make install

正向代理配置

nginx 官方没有支持正向代理的模块，只能通过加载第三方模块来实现

• 安装依赖

yum -y install pcre-devel openssl openssl-devel

• 下载二进制包

https://nginx.org/download/nginx-1.22.1.tar.gz
https://github.com/chobits/ngx_http_proxy_connect_module/archive/refs/tags/v0.0.3.tar.gz

• 安装 patch

yum install -y patch

• 编译安装

# 将nginx和ngx_http_proxy_connect_module解压到 /opt 目录下
[root@VM-0-17-centos opt]# ls
ngx_http_proxy_connect_module nginx-1.22.1
# 加载 ngx_http_proxy_connect_module
cd nginx-1.22.1/
patch -p1 < /opt/ngx_http_proxy_connect_module/patch/proxy_connect_rewrite_102101.patch
./configure --prefix=/opt/nginx --add-module=/opt/ngx_http_proxy_connect_module --with-stream --with-stream_ssl_preread_module --with-stream_ssl_module
make && make install

• 增加正向代理配置

server {
    listen                           8080;
    server_name                      localhost;
    resolver                         114.114.114.114;
    proxy_connect;
    proxy_connect_allow              443 80;
    proxy_connect_connect_timeout    10s;
    proxy_connect_read_timeout       10s;
    proxy_connect_send_timeout       10s;
    location / {
        proxy_pass $scheme://$http_host$request_uri;
    }
}
