Docker mysql8 modify password

Docker mysql8 modify password

Set skip password login

docker exec -it mysql /bin/sh
# Note: The configuration file for editing is docker.cnf
vi /etc/mysql/conf.d/docker.cnf

Restart MySQL container

docker restart mysql

Restart MySQL container

The old version of the command is invalid:
update user set password = password (‘a123456 ‘), where user =’root'</ s>

UPDATE mysql.user SET authentication_string='' WHERE user='root' and host='localhost';
-- Change the password for use without expiration
flush privileges;

Error handling

ERROR 2059 (HY000): Authentication plugin ‘caching_ sha2_ password’ cannot be loaded: /usr/lib64/mysql/plugin/caching_ sha2_ cannot open shared object file: No such file or directory

Maybe the password is not set and will never expire. Maybe the database client version under Linux is too low. I tried to connect to mysql8 of docker in server B on server a, but the connection was successful by using DataGrid in windows.

check whether the user exists: select user from user
delete: drop user 'user' @ '%
