docker部署mysql并且自动启动

Docker 部署 Mysql8.0的方法示例

1. 参照官网，安装docker 

2.拉取mysql镜像 （默认拉取最新的镜像）8.0.11

  • docker pull mysql

    • 3.在宿主机创建持久化 mysql data 及mysql.cnf 

  • mkdir /usr/local/mysqlData/test/cnf
mkdir /usr/local/mysqlData/test/data
vi /usr/loal/mysqlData/test/cnf/mysql.cnf

    •     设置本地文件共享：

        Docker -> Preferences... -> File Sharing

    4.添加操作权限 

    chmod 777 /usr/local/mysqlData/test/data     备注：挂载时权限验证（操作权限）

    5.运行镜像，设置初始密码、本机与docker端口的映射与挂载本地数据盘 (启动msyql服务)

  • docker run -itd -p 3307:3306 --name test_mysql -v /usr/local/mysqlData/test/conf:/etc/mysql
 -v /usr/local/mysqlData/test/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456 mysql

    • 运行结果：

    6. 进入test_mysql 容器

  • Docker exec -it test_mysql bash

    • 如图：

    docker部署mysql并且自动启动（Docker 部署 Mysql8.0的方法示例）

    7.在容器内登录mysql

    docker部署mysql并且自动启动（Docker 部署 Mysql8.0的方法示例）

    8.查看用户信息

  • mysql> select user,host,authentication_string from mysql.user;

+------------------+-----------+------------------------------------------------------------------------+

| user       | host   | authentication_string                         |

+------------------+-----------+------------------------------------------------------------------------+

| root       | %     | $A$005$7o{'|'AomAw(QvF#.p5wLtCnrG6yX6XQdDVQivGr96POVL.gKnhIAhUhl3. |

| mysql.infoschema | localhost | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE               |

| mysql.session  | localhost | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE               |

| mysql.sys    | localhost | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE               |

| root       | localhost | $A$005$0.-%i)H{uYi@zFo7uYF82fYw7DsA93vYLr4uZv6I1tSKao0sbzzcDap3 |

+------------------+-----------+------------------------------------------------------------------------+

5 rows in set (0.00 sec)

    • 9.设置权限（为root分配权限，以便可以远程连接）

  • mysql> grant all PRIVILEGES on *.* to root@'%' WITH GRANT OPTION;
Query OK, 0 rows affected (0.01 sec)

    • 10.由于Mysql5.6以上的版本修改了Password算法，这里需要更新密码算法，便于使用Navicat连接

  • mysql> grant all PRIVILEGES on *.* to root@'%' WITH GRANT OPTION;
Query OK, 0 rows affected (0.01 sec)

mysql> ALTER user 'root'@'%' IDENTIFIED BY '123456' PASSWORD EXPIRE NEVER;
Query OK, 0 rows affected (0.11 sec)

mysql> ALTER user 'root'@'%' IDENTIFIED WITH mysql_native_password BY '123456';
Query OK, 0 rows affected (0.11 sec)

mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.01 sec)

    • 11. 使用navicat 连接mysql,如图：

    12.建库、建表、加数据

    查看挂载本地数据盘的内容：

    13. 测试将容器移除后，数据是否仍然存在

  • docker rm -f test_msyql

    • docker部署mysql并且自动启动（Docker 部署 Mysql8.0的方法示例）

    容器已经移除了。重新部署test_mysql,参照第5的步骤，进入新容器，访问数据库：

  • xushijiandeiMac:data xushijian$ docker run -itd -p 3307:3306 --name test_mysql -v /usr/local/mysqlData/test/conf:/etc/mysql -v /usr/local/mysqlData/test/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456 mysql
65b7a60050aaef5765ed055acfd071c7c76f60e85dc25d0e73e0d56eae14aed1
xushijiandeiMac:data xushijian$ docker exec -it test_mysql bash
root@65b7a60050aa:/# mysql -uroot -p

    • 发现数据仍然可以使用，不需要额外的配置，实现了数据的持久化。

    阿里云上docker 部署 MySQL(通过编排模板部署)

    <1. 配置同第3步类似（只是目录变化）

  • master:
 image: 'mysql:latest'
 environment:
  - MYSQL_ROOT_PASSWORD=123456
 ports:
  - '3307:3306/tcp'
 volumes:
  - '/usr/local/mysqlData/master/conf:/etc/mysql:rw'
  - '/usr/local/mysqlData/master/data:/var/lib/mysql:rw'
 labels:
  aliyun.scale: '1'

    • <2.如下图,已部署完成

  • [root@c13a6d832fd0a49398c62002361d75c60-node1 ~]# clear
[root@c13a6d832fd0a49398c62002361d75c60-node1 ~]# docker ps

    <3.进入容器，进行权限设置，后续过程参照本机

  • [root@c13a6d832fd0a49398c62002361d75c60-node1 /]# docker exec -it mysql_master_1 bash
root@2fc0bbf48941-mysql-master-1:/# mysql -uroot -p

    • 主从库原理分析：

    docker部署mysql并且自动启动（Docker 部署 Mysql8.0的方法示例）

    i/o线程去请求主库 的binlog，并将得到的binlog日志写到relay log（中继日志） 文件中； 主库会生成一个 log dump 线程，用来给从库 i/o线程传binlog；  

    SQL 线程，会读取relay log文件中的日志，并解析成具体操作，来实现主从的操作一致，而最终数据一致；

    即： 从库IO线程请求 -> 中继日志 ->获取binlog ->从库SQL线程，解析
