Docker-部署MySQL

Docker-MySQL

使用官方镜像快速启动一个MySQL Server实例（MySQL8）

如下

FengZhen$ docker run --name mysql -e MYSQL_ROOT_PASSWORD=123456 -p 53306:3306 -d mysql:latest
906b498c04db2bfe57349760941222ca063c3b169885969c95e5656a55c3a6ff
FengZhen$ docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                     NAMES
906b498c04db        mysql:latest        "docker-entrypoint.s…"   9 seconds ago       Up 12 seconds       0.0.0.0:53306->3306/tcp   mysql

进入MySQL

FengZhen$ docker exec -it 906b498c04db mysql -u root -p
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH  GRANT OPTION;
Query OK, 0 rows affected (0.00 sec)
mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.01 sec)

 

在宿主主机进入MySQL

FengZhen$ mysql -u root -p -h192.168.1.102 -P53306

使用Navicat连接失败

Authentication plugin 'caching_sha2_password' cannot be loaded: dlopen(/usr/local/mysql/lib/plugin/caching_sha2_password.so, 2): image not found

解决：

 修改账户密码加密规则并更新用户密码

   ALTER USER 'root'@'localhost' IDENTIFIED BY 'password' PASSWORD EXPIRE NEVER;   #修改加密规则 

   ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';   #更新一下用户的密码 

3. 刷新权限并重置密码

   FLUSH PRIVILEGES;   #刷新权限 

 

MySQL5.7.4

启动MySQL容器

 

FengZhen$ docker run -it --name mysql5.7.4 -p 53307:3306 -e MYSQL_ROOT_PASSWORD=123456 daocloud.io/library/mysql:5.7.4

 

进入MySQL，修改权限

FengZhen$ docker exec -it mysql5.7.4 mysql -u root -p
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION;
Query OK, 0 rows affected (0.00 sec)
mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)

本地连接测试

FengZhen$ mysql -u root -p -h192.168.1.102 -P53307

使用Navicat连接。
