1. Installation
docker run -it -p 3306:3306 --name mysql1 -v ~/mysql/conf/my.cnf:/etc/mysql/my.cnf -v ~/mysql/logs:/logs -v ~/mysql/data:/mysql_data -e MYSQL_ROOT_PASSWORD=123456 -d docker.io/mysql /bin/bash
2. Container startup
3. After entering the container with attach, I did not see the mysql process
1. It shows that mysql did not start, because the /bin/bash behind you has exposed the problem.
2. Try starting like this
$docker run -d mysql $docker exec -it $container_id /bin/bash
The cause of the problem can be found in the official description of CMD and entrypoint instructions.
The following is my test results
#1. Simulate your effect. No error will be reported here, because mysqld was not executed for initialization and bash has already overwritten the instruction docker@default:~$ docker run -it mysql bash root@8b767c162afd:/# ps -aux | grep mysql root 7 0.0 0.0 11128 984 ? S+ 03:04 0:00 grep mysql #2. An error was reported because no -e environment parameter was added, which indicates that mysqld performed initialization and no environment variable was found. docker@default:~$ docker run -d mysql 9212525aedf8f5586548fbc1d1e4fa130fd0ce294ac03c2d00a1c1d9945455a5 docker@default:~$ docker exec -it 92 bash Error response from daemon: Container 9212525aedf8f5586548fbc1d1e4fa130fd0ce294ac03c2d00a1c1d9945455a5 is not running mysql-db docker@default:~$ docker logs 92 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 docker@default:~$
