问题1

问题描述

• docker-compose.yml 中使用 $SECRET_KEY 和 $BOOTSTRAP_TOKEN加载 ~/.bashrc 环境变量时无法加载
• 代码中写法:

  version: '3'
  services:
      ......
  	jms_all:
  	    image: jumpserver/jms_all:v3.10.10
  	    container_name: jms_all
  	    ports:
  	      - "80:80"
  	      - "2222:2222"
  	    environment:
  	      SECRET_KEY: $SECRET_KEY
  	      BOOTSTRAP_TOKEN: $BOOTSTRAP_TOKEN
  	      LOG_LEVEL: ERROR
  	      DB_HOST: jms_mysql
  	      DB_PORT: 3306
  	      DB_USER: jumpserver
  	      DB_PASSWORD: 123456
  	      DB_NAME: jumpserver
  

---

原因分析

• 命令行使用 echo $SECRET_KEY 可以打印环境变量, docker-compose.yml 无法加载原因不明。

---

解决方案

• 直接使用bashrc中定义的SECRET_KEY和BOOTSTRAP_TOKEN的值， 如下

  version: '3'
  services:
      ......
  	jms_all:
  	    image: jumpserver/jms_all:v3.10.10
  	    container_name: jms_all
  	    ports:
  	      - "80:80"
  	      - "2222:2222"
  	    environment:
  	      SECRET_KEY: 0vwLw0vfmIf1NsjkrgxXJoA0HyXB7QajWIHVpPQVsdxa9ydUkg
  	      BOOTSTRAP_TOKEN: V9BXZzUzlG2UYLOu
  	      LOG_LEVEL: ERROR
  	      DB_HOST: jms_mysql
  	      DB_PORT: 3306
  	      DB_USER: jumpserver
  	      DB_PASSWORD: 123456
  	      DB_NAME: jumpserver
  

问题2

问题描述

• jumpserver启动后可以访问登录页面， 登录后提示服务器错误

  Server error occur, contact administrator
  

---

原因分析

• jumpserver第一次启动时候会初始化数据库， 由于数据库编码默认为latin1, 会导致中文出错， 需要修改编码为utf8, 通过配置文件挂载的方式修改后， 发现仍然报错，挂载配置失败。
• sudo docker-compose logs jms_all查看jms_all的启动日志, 中文编码出错

  jms_all    | After migration, update builtin role permissions
  jms_all    |   - Update builtin roles
  jms_all    | 2024-06-08 23:32:37 Install builtin applets
  jms_all    | (1366, "Incorrect string value: '\\xE6\\xB5\\x8F\\xE8\\xA7\\x88...' for column 'display_name' at row 1")
  jms_all    | (1366, "Incorrect string value: '\\xE7\\xA4\\xBE\\xE5\\x8C\\xBA...' for column 'display_name' at row 1")
  

• sudo docker-compose logs mysql 查看mysql启动日志， 发现配置文件没有加载

  mysqld: [Warning] World-writable config file '/etc/mysql/conf.d/my.cnf' is ignored.
  

• 进入mysql容器进行检查
  • 使用命令

    # 进入容器
    sudo docker exec -it jms_mysql bash
    # 进入数据库
    mysql -uroot -p123456
    # 选择jumpserver数据库
    use jumpserver
    # 查看数据库使用的编码集
    SHOW VARIABLES LIKE 'character_set%';
    SHOW VARIABLES LIKE 'collation%';
    

  • 得到结果显示编码仍为latin

     # SHOW VARIABLES LIKE 'character_set%';
      +--------------------------+----------------------------+
      | Variable_name            | Value                      |
      +--------------------------+----------------------------+
      | character_set_client     | latin1                     |
      | character_set_connection | latin1                     |
      | character_set_database   | latin1                     |
      | character_set_filesystem | binary                     |
      | character_set_results    | latin1                     |
      | character_set_server     | latin1                     |
      | character_set_system     | utf8                       |
      | character_sets_dir       | /usr/share/mysql/charsets/ |
      +--------------------------+----------------------------+
      # SHOW VARIABLES LIKE 'collation%';
      +----------------------+-------------------+
      | Variable_name        | Value             |
      +----------------------+-------------------+
      | collation_connection | latin1_swedish_ci |
      | collation_database   | latin1_swedish_ci |
      | collation_server     | latin1_swedish_ci |
      +----------------------+-------------------+

解决方案

• 修改配置文件的权限

  cd /data/docker/jumpserver/mysql/conf/
  sudo chmod 644 my.cnf
  

• 重新启动

  # 停止容器
  sudo docker-compose down
  # 删除mysql数据文件
  sudo rm -rf /data/docker/jumpserver/mysql/data/*
  # 重启容器
  sudo docker-compose up -d
