docker offline installation mysql

docker offline installation mysql

• Step 1: Find a networked server with docker installed, check the current docker image: docker images, pull the mysql image package: docker save -o mysql.tar mysql:latest, where latest is the content of the tag line

• Step 2: Copy the downloaded mysql.tar to /opt/softthe folder

• Step 3: Run the command to load the mysql image:docker load -i mysql.tar

• Step 4: View the docker image: docker images, and find that it contains the mysql image

• Step 5: Create mysql container:

  docker run -p 3306:3306 --name mysql --restart=always --privileged=true \
  
  -v /usr/local/mysql/log:/var/log/mysql \
  
  -v /usr/local/mysql/data:/var/lib/mysql \
  
  -v /usr/local/mysql/conf:/etc/mysql \
  
  -v /etc/localtime:/etc/localtime:ro \
  
  -e MYSQL_ROOT_PASSWORD=123456 -d mysql:latest
  

  explain:

  -p 3306:3306：指定宿主机端口与容器端口映射关系
  
  --name mysql：创建的容器名称
  
  --restart=always：总是跟随docker启动
  
  --privileged=true：获取宿主机root权限
  
  -v /usr/local/mysql/log:/var/log/mysql：映射日志目录，宿主机:容器
  
  -v /usr/local/mysql/data:/var/lib/mysql：映射数据目录，宿主机:容器
  
  -v /usr/local/mysql/conf:/etc/mysql：映射配置目录，宿主机:容器
  
  -v /etc/localtime:/etc/localtime:ro：让容器的时钟与宿主机时钟同步，避免时区的问题，ro是read only的意思，就是只读。
  
  -e MYSQL_ROOT_PASSWORD=123456：指定mysql环境变量，root用户的密码为123456
  
  -d mysql:latest：后台运行mysql容器，版本是latest。
  

• Step 6: Check whether the installation is successful: docker ps -aIf the status is restarting, put the my.cnf configuration file in the directory: /usr/local/mysql/confand restart mysql to make the configuration take effect:docker restart mysql

  my.cnf配置
  
  [client]
  
  default-character-set=utf8mb4
  
  [mysql]
  
  default-character-set=utf8mb4
  
  [mysqld]
  
  # 设置东八区时区
  default-time_zone = '+8:00'
  
  # 设置密码验证规则，default_authentication_plugin参数已被废弃
  
  # 改为authentication_policy
  
  #default_authentication_plugin=mysql_native_password
  authentication_policy=mysql_native_password
  
  # 限制导入和导出的数据目录
  # 为空，不限制导入到处的数据目录；
  # 指定目录，必须从该目录导入到处，且MySQL不会自动创建该目录；
  # 为NULL，禁止导入与导出功能
  #secure_file_priv=/var/lib/mysql
  secure_file_priv=
  
  init_connect='SET collation_connection = utf8mb4_0900_ai_ci'
  
  init_connect='SET NAMES utf8mb4'
  
  character-set-server=utf8mb4
  
  collation-server=utf8mb4_0900_ai_ci
  
  skip-character-set-client-handshake
  
  skip-name-resolve
  

• Step 7: Enter the container interaction interface:docker exec -it mysqlserver bash

• Step 8: mysql -u root -pIf my.cnf in Step 6 is configured in front, do not enter the password and press Enter directly to enter. Remember to change the password authentication method:
  ALTER USER root@'%' IDENTIFIED WITH mysql_native_password BY '123456';

• Step 9: Open remote connection permissions

  use mysql
  
  select host,user from user;
  
  update user set host='%' where user='root';
  
  flush privileges;
  

• Step 10: navicat tests connection to mysql
