1 缘起

开启容器化之路。

2 容器化MySQL

2.1 查看MySQL镜像

docker search mysql

2.2 指定版本：5.7.30

通过官网查看：https://hub.docker.com/

docker pull mysql:5.7.30

2.3 路径挂载

容器路径挂载到宿主机。

• 新建宿主机路径

mkdir -p /home/xindaqi/mysql/data /home/xindaqi/mysql/logs /home/xindaqi/mysql/conf

序号	路径	描述
1	/home/xindaqi/mysql/data	MySQL存储的数据
2	/home/xindaqi/mysql/logs	MySQL日志
3	/home/xindaqi/mysql/conf	MySQL配置

• 添加配置文件：my.cnf
  /home/xindaqi/mysql/conf/my.cnf

[mysqld]
user=mysql
bind-address = 0.0.0.0
character-set-server=utf8
default_authentication_plugin=mysql_native_password
expire_logs_days=7
sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION
max_connections=1000
[client]
default-character-set=utf8
[mysql]
default-character-set=utf8

2.4 运行

序号	参数	描述
1	p	服务端口映射，宿主机端口:容器内端口
2	name	服务名称
3	v	路径挂载，宿主机路径:容器内路径
4	e	MySQL root账户密码

• 前台运行

docker run -p 3306:3306 \
--name mysql \
-v /home/xindaqi/mysql/conf/my.cnf:/etc/mysql/my.cnf \
-v /home/xindaqi/mysql/logs:/var/log/mysql \
-v /home/xindaqi/mysql/data:/var/lib/mysql \
-e MYSQL_ROOT_PASSWORD=my$123456 \
 mysql:5.7.30

• 后台运行

docker run -p 3306:3306 \
--name mysql \
-v /home/xindaqi/mysql/conf/my.cnf:/etc/mysql/my.cnf \
-v /home/xindaqi/mysql/logs:/var/log/mysql \
-v /home/xindaqi/mysql/data:/var/lib/mysql \
-e MYSQL_ROOT_PASSWORD=my$123456 \
-d mysql:5.7.30

2.5 查看容器

docker container ls | grep mysql

2.6 进入容器

# 格式
docker exec -it container_id /bin/bash
# 样例
docker exec -it 916f93180fb2 /bin/bash

2.7 登录MySQL：Ubuntu内

• 查看系统IP

ifconfig

使用enth0的网络IP登录MySQL。

• 登录MySQL

mysql -h 172.22.75.234 -uroot -pmy$123456

2.8 新建用户

用于其他服务使用，
因为，使用root登录时，无法接入MySQL，所以新建用户。

# 新增用户：格式create user username@ip identified by password
create user 'mysql-username'@'%' identified by 'my$123456';

序号	参数	描述
1	mysql-username	用户名
2	%	IP，其中，%表示允许所有IP连接
3	my$123456	密码

# 授权，格式：grant operation on database to username@ip identified by password
grant all on *.* to 'mysql-username'@'%' identified by 'my$123456';

序号	参数	描述
1	all	所有操作，单独配置操作：select、insert、update和delete
2	.	表示所有数据库，可以单独指定某个数据库和某些表，如database-name.*,database-name.table-name
3	mysql-username	用户名
4	my$123456	用户密码

# 生效
flush privileges;

查看用户

select host, user from mysql.user;
