1. Check whether the docker environment is normal
Use on the command line docker search mysql:
If you can find out that the docker installation is no problem, then start the next step
Second, download the mysql mirror
Pull the mysql image (default is the latest version)
docker pull mysql
If you need to specify the version number, use:
docker pull mysql:版本号
docker official website: https://hub.docker.com/
You can see some version numbers of mysql from the official website tag
Three, check whether the Mysql image is downloaded successfully
View all mirrors
docker images
Fourth, create a Mysql container
docker run --name mysql01 -p 3306:3306 -e MYSQL_ROOT_PASSWORD=root -d mysql
-p 3306:3306: Map the 3306 port of the host to the 3306 port of the mysql container, and the mysql container can be accessed from the outside through the host ip+3306.
After execution, use docker ps to view the running container:
Enter the mysql container:
$ docker exec -it mysql01 bash
Enter the account and password to log in to mysql:mysql -uroot -proot
#Exit mysql
exit
#Exit the mysql container
exit
In this case, the mysql container can run
Five, test external links
Connecting tools such as sqlyog or Navicat cannot be successfully connected externally! ! !
During this process, mine reported a 1251 error. It was also successfully resolved.
Six, solve the customer service end link mysql report 1251
Enter mysql again
1. Enter the container:
[root@localhost ~]# docker exec -it mysql01 bash
2. Enter mysql:
root@2288abcb04f3:/# mysql -uroot -proot
3. Authorize the remote connection:
mysql> GRANT ALL ON *.* TO 'root'@'%';
4. Encryption rules for changing the password:
mysql> ALTER USER 'root'@'%' IDENTIFIED BY 'password' PASSWORD EXPIRE NEVER;
5. Change root's password:
mysql> ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY '123456';
6. Refresh permissions:
mysql> flush privileges;
7. Use the client to test;
