nginx正向代理服务器搭建
场景：由于网络环境限制，只能通过代理服务器访问外网，代理服务器自己部署、由于业务需求容器或者k8s的pod也需要通过代理访问外网
代理服务器搭建：系统CentOS 7，通过编译安装nginx实现正向代理功能
代理服务器（CentOS 7）：180.76.189.xxx 192.168.0.15
内网服务器（Ubuntu16.04）：192.168.0.150
步骤如下：
1、编译安装nginx
yum -y install gcc gcc-c++ autoconf automake pcre pcre-devel openssl openssl-devel patch git net-tools
mkdir -p /downloads && cd /downloads
wget http://nginx.org/download/nginx-1.17.2.tar.gz && tar -xf nginx-1.17.2.tar.gz
git clone https://github.com/chobits/ngx_http_proxy_connect_module.git
cd nginx-1.17.2
patch -p1 </downloads/ngx_http_proxy_connect_module/patch/proxy_connect_rewrite_101504.patch
./configure --add-module=/downloads/ngx_http_proxy_connect_module
make && make install
2、把nginx配置systemctl管理
#cat vi /usr/lib/systemd/system/nginx.service
[Unit]
Description=The NGINX HTTP and reverse proxy server
After=syslog.target network.target remote-fs.target nss-lookup.target
[Service]
Type=forking
PIDFile=/usr/local/nginx/logs/nginx.pid
ExecStartPre=/usr/local/nginx/sbin/nginx -t
ExecStart=/usr/local/nginx/sbin/nginx
ExecReload=/usr/local/nginx/sbin/nginx -s reload
ExecStop=/usr/bin/kill -s QUIT $MAINPID
PrivateTmp=true
[Install]
WantedBy=multi-user.target
3、配置nginx代理规则
cp /usr/local/nginx/conf/nginx.conf /usr/local/nginx/conf/nginx.conf.bak
vi /usr/local/nginx/conf/nginx.conf

}

}

内网服务器配置代理
1、系统代理
cat /etc/profile && source /etc/profile
http_proxy=http://192.168.0.15:8080/
https_proxy=https://192.168.0.15:8443/
ftp_proxy=http://192.168.0.15:8080/
export http_proxy
export https_proxy
export ftp_proxy
2、wget代理
cat /etc/wgetrc
http_proxy=http://192.168.0.15:8080/
https_proxy=https://192.168.0.15:8443/
ftp_proxy=http://192.168.0.15:8080/
3、配置apt代理
cat /etc/apt/apt.conf && apt-get update
Acquire::http::proxy "http://192.168.0.15:8080/";
Acquire::https::proxy "https://192.168.0.15:8443/";
Acquire::ftp::proxy "ftp://192.168.0.15:8080/";
4、安装docker
apt-get -y install apt-transport-https ca-certificates curl software-properties-common
curl -fsSL http://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo apt-key add -
add-apt-repository "deb [arch=amd64] http://mirrors.aliyun.com/docker-ce/linux/ubuntu $(lsb_release -cs) stable"
apt-get -y update
apt-cache madison docker-ce
apt-get -y install docker-ce=18.06.3~ce~3-0~ubuntu
5、配置docker代理
mkdir -p /etc/systemd/system/docker.service.d/
cat /etc/systemd/system/docker.service.d/http-proxy.conf
[Service]
Environment="HTTP_PROXY=http://192.168.0.15:8080"
Environment="HTTPS_PROXY=http://192.168.0.15:8443"
mkdir .docker
cat .docker/config.json
{
"proxies":
{
"default":
{
"httpProxy": "http://192.168.0.15:8080",
"httpsProxy": "http://192.168.0.15:8443",
"noProxy": "*.test.example.com,.example2.com"
}
}
}
systemctl daemon-reload
systemctl restart docker
