Solution For "docker-entrypoint.sh: line 83: mysqld: command not found" while running mysql in docker
While I was trying to run mysql database in my local linux machine through docker it was giving me some wired error. This is how I solved this
My Environment
OS: Linux / Ubuntu 20.04
Docker version: 19.03.13
Error
$docker-compose up --build db Creating docker-mysql ... done Attaching to docker-mysql docker-mysql | 2020-10-10 10:52:55+00:00 [Note] [Entrypoint]: Entrypoint script for MySQL Server 8.0.21-1debian10 started. docker-mysql | 2020-10-10 10:52:55+00:00 [ERROR] [Entrypoint]: mysqld failed while attempting to check config docker-mysql | command was: mysqld --default-authentication-plugin=mysql_native_password --verbose --help docker-mysql | /usr/local/bin/docker-entrypoint.sh: line 83: mysqld: command not found
Apparently this message /usr/local/bin/docker-entrypoint.sh: line 83: mysqld: command not found, means that some executables are missing in my image. but I have have no idea how any images have missing executable. Anyway I tried many different ways but only one worked for me
Solution
This is what I did which solved the problem for me
- Stopped & removed my failing my container
- Removed the mysql image
- Run the docker-compose up command again
See the code snippet for the command
Final Output

See the final message /usr/sbin/mysqld: ready for connections which tells me that my mysql instance is running fine and ready to connect
