Docker通过挂载安装mysql

一、安装 

 mkdir -p ./docker/mysql
 cd docker/
 cd mysql/
 mkdir conf
 mkdir data
 mkdir logs

 mkdir mysql-files

cd conf 

vim my.cnf

　　[mysqld]

　　user=mysql

 docker pull mysql
 docker run -e MYSQL_ROOT_PASSWORD=KMSD2016064 -d -p 3306:3306 --name mysql01 mysql

 

docker run -e MYSQL_ROOT_PASSWORD=KMSD2016064 -d -p 3306:3306 -v ~/docker/mysql/conf/my.cnf:/etc/mysql/my.cnf -v ~/docker/mysql/data:/var/lib/mysql -v ~/docker/mysql/logs:/logs -v ~/docker/mysql/mysql-files:/var/lib/mysql-files --name mysql01 mysql

二、修改默认字符集并创建用户

docke exec -it mysql01 bash

mysql -uroot -p

修改默认字符集

show variables like '%char%'

+--------------------------+--------------------------------+
| Variable_name | Value |
+--------------------------+--------------------------------+
| character_set_client | latin1 |
| character_set_connection | latin1 |
| character_set_database | utf8mb4 |
| character_set_filesystem | binary |
| character_set_results | latin1 |
| character_set_server | utf8mb4 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql-8.0/charsets/ |
+--------------------------+--------------------------------+

vim mycnf

#insert
[mysqld]
user=mysql
character-set-server=utf8

[client]
default-character-set=utf8

[mysql]
default-character-set=utf8

mysql> show variables like '%char%';
+--------------------------+--------------------------------+
| Variable_name | Value |
+--------------------------+--------------------------------+
| character_set_client | utf8 |
| character_set_connection | utf8 |
| character_set_database | utf8 |
| character_set_filesystem | binary |
| character_set_results | utf8 |
| character_set_server | utf8 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql-8.0/charsets/ |
+--------------------------+--------------------------------+
8 rows in set (0.01 sec)

使用Navicat访问，由于使用的是mysql最新版本，mysql8 之前的版本中加密规则是mysql_native_password,而在mysql8之后,加密规则是caching_sha2_password，加密方式变了

　　alter user 'root'@'%' identified by 'KMSD2016064' password expire never; 改变加密方式

　　alter user 'root'@'%' identified with mysql_native_password by 'KMSD2016064'; 更新用户密码

　　flush privileges;

正常情况下我们不会把root暴露出去，所以需要创建新的用户

　　create user 'jesen'@'%' identified by 'KMSD2016064';

　　grant all privileges on *.* to 'jesen'@'%';

　　alter user 'jesen'@'%' identified with mysql_native_password by 'KMSD2016064';

三、官方参考

　　字符集编码和创建用户密码也可以在docker run 的时候指定，具体可参考 https://dev.mysql.com/doc/mysql-installation-excerpt/5.7/en/docker-mysql-more-topics.html：

　　docker run -d -p 3306:3306 -e MYSQL_USER="test" -e MYSQL_PASSWORD="password" -e MYSQL_ROOT_PASSWORD="password" --name [Name] [ImageName] --character-set-server=utf8 --collation-server=utf8_general_ci
