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. Use a local account to create a folder for mapping Configuration file of mysql in docker

Continue to create 3 folders: conf, data, and logs

My configuration is as follows

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

3. Create mysql container

Switch to the root account and enter the mysql1 folder you just created

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

Create and start the container

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

Give root Set the password 123456

4. Start the mysql container

docker start mysql11

5. Enter the mysql bash

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

where env LANG= C.UTF-8 bash allows the docker command line to support Chinese

6. Copy the configuration file

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

7. Log in to mysql

mysql -u root -p

Enter the password

8. Check the mysql encoding

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)

and find that it is not utf-8 encoding

9. Modify the mysql encoding

Exitmysql, exit docker

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

Modify my.cnf configuration file

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

Press i to enter

edit mode

Join

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

10. Restart docker’s mysql and check the encoding again

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:
