1. 下载v2ray软件包

wget https://github.com/v2ray/v2ray-core/releases/download/v4.22.1/v2ray-linux-64.zip

2. 解压缩软件包

 unzip v2ray-linux-64.zip 

3. 写入客户端配置

具体参数根据你的服务器设定来

cat  config.json
{
  "policy" : {
    "levels" : {
      "0" : {
        "uplinkOnly" : 0
      }
    }
  },

    "servers" : [
      "localhost"
    ]
  },

      }
    }

            "geoip:private"
          ]
        }
      ]
    }
  },
  "outbound" : {
    "sendThrough" : "0.0.0.0",
    "mux" : {
      "enabled" : false,
      "concurrency" : 8
    },
    "protocol" : "vmess",
    "settings" : {
      "vnext" : [
        {

            }
          ],
          "remark" : "rongge"
        }
      ]
    },
    "streamSettings" : {
      "wsSettings" : {
        "path" : "",
        "headers" : {
          "Host" : "youraddress.com"
        }
      },
      "tlsSettings" : {
        "serverName" : "youraddress.com",
        "allowInsecure" : false
      },
      "httpSettings" : {
        "path" : "",

          ""
        ]
      },
      "tcpSettings" : {

        "readBufferSize" : 1,
        "downlinkCapacity" : 20
      },
      "network" : "tcp",
      "security" : "none"
    }
  }
}

4. 启动v2ray到后台运行

./v2ray --config=config.json &

临时设置全局HTTP和HTTPS代理，该配置对docker加速镜像拉取无效，仅能用于网页访问加速，此处v2ray客户端和代理在同一台服务器，故使用127.0.0.1地址，局域网内其他服务器需要使用该代理，地址需修改为代理所在服务器内网IP，并检查iptables和安全组设置

export https_proxy=https://127.0.0.1:8001
export http_proxy=http://127.0.0.1:8001

5. 创建文件

mkdir /etc/systemd/system/docker.service.d

6. 修改文件

vim  /etc/systemd/system/docker.service.d/http-proxy.conf

加入如下配置，设置docker使用HTTP代理，局域网内其服务器需要将127.0.0.1改为代理服务器IP

[Service]
Environment="HTTP_PROXY=http://127.0.0.1:8001"

7. 重启服务

systemctl daemon-reload
systemctl restart docker

8. 查看docker信息，是否包含HTTP代理信息

docker info

9. 拉取docker镜像测试加速效果

docker pull gcr.io/google-containers/hpa-example:lastest
