ubuntu下在docker中安装mysql5.6实例详解

1.安装mysql5.6

docker run mysql:5.6

等所有项目都是Download complet 安装完毕

Status: Downloaded newer image for mysql:5.6
error: database is uninitialized and password option is not specified 
 You need to specify one of MYSQL_ROOT_PASSWORD, MYSQL_ALLOW_EMPTY_PASSWORD and MYSQL_RANDOM_ROOT_PASSWORD

2.使用本地账号创建一个文件夹用来映射docker中mysql的配置文件

其中继续创建conf、data、logs 3个文件夹

我的配置如下

val@val-linux:~/docker/mysql1$ pwd
/home/val/docker/mysql1
val@val-linux:~/docker/mysql1$ ls
conf data logs

3.创建mysql容器

切换到root账号进入到刚才创建的mysql1文件夹中

root@val-linux:/home/val# cd /home/val/docker/mysql1/
root@val-linux:/home/val/docker/mysql1#

创建并启动容器

docker run -p 33061:3306 --name mysql1 -v $PWD/conf:/etc/mysql -v $PWD/logs:/logs -v $PWD/data:/mysql_data -e MYSQL_ROOT_PASSWORD=123456 -d mysql:5.61
用本地33061端口映射docker的3306端口 
给容器命名mysql1 
用本地/home/val/docker/mysql1/conf映射mysql的conf 
用本地/home/val/docker/mysql1/logs映射mysql的logs 
用本地/home/val/docker/mysql1/data映射mysql的mysql_data

给root设置密码123456

4.启动mysql容器

docker start mysql11

5.进入mysql的bash

docker exec -it mysql1 env LANG=C.UTF-8 bash

其中 env LANG=C.UTF-8 bash 让docker命令行支持中文

6.复制配置文件

cp /usr/my.cnf /etc/mysql/my.cnf

7.登录mysql

mysql -u root -p

输入密码进入

8.查看mysql编码

mysql> show variables like '%character%';
+--------------------------+----------------------------+
| Variable_name      | Value           |
+--------------------------+----------------------------+
| character_set_client   | latin1           |
| character_set_connection | latin1           |
| character_set_database  | latin1           |
| character_set_filesystem | binary           |
| character_set_results  | latin1           |
| character_set_server   | latin1           |
| character_set_system   | utf8            |
| character_sets_dir    | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
8 rows in set (0.01 sec)

发现不是utf-8编码

9.修改mysql编码

退出mysql，退出docker

mysql> exit
Bye
root@8b83a30acbf8:/# exit
exit
root@val-linux:/home/val/docker/mysql1#

修改my.cnf配置文件

root@val-linux:/home/val/docker/mysql1# vim conf/my.cnf

按i进入编辑模式

加入

[client] default-character-set=utf8 
[mysql] default-character-set=utf8 
[mysqld] character-set-server=utf8 1
esc :wq! 保存退出

10.重启docker的mysql再次查看编码

root@val-linux:/home/val/docker/mysql1# docker stop mysql1
mysql1
root@val-linux:/home/val/docker/mysql1# docker start mysql1
mysql1
root@val-linux:/home/val/docker/mysql1# docker exec -it mysql1 env LANG=C.UTF-8 bash
root@8b83a30acbf8:/# mysql -u root -p
Enter password:

+--------------------------+----------------------------+
8 rows in set (0.00 sec)

11.创建数据库

mysql> create database rise;
Query OK, 1 row affected (0.00 sec) 
mysql> use rise;
Database changed

12.创建用户并授权

mysql> grant all privileges on rise.* to val@'%' identified by '123456';
Query OK, 0 rows affected (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

%表示任意IP（可以指定IP）、val是用户名、123456是密码
