Basic Steps for MySQL Server Deployment with Docker
1 Find a suitable mysql image and select the appropriate version
docker search -f stars=3 -f is-official=true mysql--find tag is mysql, stars greater than 3 official images
2 downloads
docker pull mysql:5.7
3 run
（1）docker run -d --name mysql01 mysql:5.7
It means that the log (docker logs mysql01) cannot be started normally, and the specified parameters need to be passed in during runtime.
错误提示：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）docker run -d -e MYSQL_ROOT_PASSWORD=password --name mysql01 mysql:5.7
4 View log
docker logs mysql01
5 Check the operation
docker ps
6 Access the mysql container
docker exec –it mysql01 bash
7 Create a new user
mysql> CREATE USER 'jack'@'localhost' IDENTIFIED BY 'pwd123456';
mysql> GRANT ALL PRIVILEGES ON *.* TO 'jack'@'localhost' WITH GRANT OPTION;
mysql> CREATE USER 'jack'@'%' IDENTIFIED BY 'pwd123456';
mysql> GRANT ALL PRIVILEGES ON *.* TO 'jack'@'%'
->WITH GRANT OPTION;
Mysql configuration and data content mount volume
Key: The mapping of the file system on the Host to the files in the docker container
1 Create a custom directory on the host where the user stores configuration and data for the mapping of the corresponding files in the docker mysql container
for example:
| host directory |
mysql docker container directory |
| /root/Software/docker/mysql/config/my.cnf |
/etc/my.cnf |
| /root/Software/docker/mysql/data |
/ var / lib / mysql |
Indicates that the newly created my.cnf file under the host needs initial content
my.cnf:
[mysqld]
user=mysql
2 run
docker run -d -p 3307:3307 -v=/root/Software/docker/mysql/config/my.cnf:/etc/my.cnf -v=/root/Software/docker/mysql/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=password --name mysql01 mysql:5.7
2 bash Enter the mysql01 docker container, log in to mysql to view the default character set
> docker exec -it mysql01 bash
>mysql –uroot –p
......
>show variables like ‘%char%’;
Description: Display as the lanti character set
3 Modify the mysql character set to utf-8, complete by modifying my.cnf
my.cnf:
[mysqld]
user=mysql
character-set-server=utf8
[client]
default-character-set=utf8
[mysql]
default-character-set=utf8
4 Delete the current container
>docker stop mysql01
>docker rm mysql01
5 Restart a new container
docker run -d -p 3307:3307 -v=/root/Software/docker/mysql/config/my.cnf:/etc/my.cnf -v=/root/Software/docker/mysql/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=password --name mysql01 mysql:5.7
6 Check the character set. At this time, the previously modified character set utf-8 is used by default
Description: The configuration is shared. Purpose: After the container is deleted, the data file will also be deleted. Mounting can realize data persistence and sharing.
