#### 安装教程
1. 把 url-forwarder jar 包、项目./install 目录下的 *.sh 文件复制到转发服务器上，  
   如目录：/data/software/url-forwarder
    ```bash
    mkdir -p /data/software/url-forwarder
    
    // 复制 url-forwarder jar 包、项目./install 目录下的 *.sh
    rz -y
    ...
   
    // 复制 application.yml
    cp ./src/main/resources/application.yml /data/software/url-forwarder
    
    // 目录结构
    tree /data/software/url-forwarder/
    /data/software/url-forwarder/
    ├── install.sh  // 安装脚本
    ├── update.sh
    ├── application.yml  // 配置文件
    ├── url-forwarder-0.0.1-SNAPSHOT.jar  // 应用 jar 包
    └── url-forwarder.service  // 应用的 systemctl 脚本
    ```

2. 安装 url-forwarder.service
    ```bash
    cd /data/software/url-forwarder
    bash ./install.sh
    ```
3. 运行 url-forwarder
    ```bash
    systemctl start url-forwarder.service
    ```
* nignx 代理 url-forwarder

  新建 /etc/nginx/conf.d/url-forwarder.conf
    ```bash
    upstream  url_forwarder {
        server 127.0.0.1:8080 weight=10 max_fails=0;
    }
    
    server {
        listen 80 default_server;
        server_name  _;
        charset utf-8;
        access_log  /data/logs/nginx_log/url-forwarder.log  main;
    
        location / {            
            proxy_pass http://url_forwarder/;
            proxy_redirect off;
            proxy_set_header   Host             $host;
            proxy_set_header   X-Real-IP        $remote_addr;
            # proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;
        }
    }
    ```

#### 其他
* 问题1
    ```bash
    $ journalctl -xeu url-forwarder
    May 06 18:26:29 149acd536b26 java[699]: Caused by: com.mysql.cj.exceptions.UnableToConnectException: Public Key Retrieval is not allowed
    ...
    ```
    * 解决方法1：连接MySQL的URl中添加不添加 `useSSL=false`，缺省为 `useSSL=true`  
      修改 application.yml
        ```yaml
        spring:
          # 数据源配置
          datasource:
            # MySQL
            driver-class-name: com.mysql.cj.jdbc.Driver
            url: jdbc:mysql://127.0.0.1:3306/dns?useUnicode=true&characterEncoding=UTF-8&serverTimezone=GMT%2B8&allowMultiQueries=true
        ```  
    * 解决方法2：连接MySQL的URl中添加`&allowPublicKeyRetrieval=true`  
      修改 application.yml
        ```yaml
        spring:
          # 数据源配置
          datasource:
            # MySQL
            driver-class-name: com.mysql.cj.jdbc.Driver
            url: jdbc:mysql://127.0.0.1:3306/dns?useUnicode=true&characterEncoding=UTF-8&serverTimezone=GMT%2B8&allowMultiQueries=true&useSSL=false&allowPublicKeyRetrieval=true
        ```
