How to execute query using script in MySQL Docker image? - mysql

Question

I am trying to give user a web interface in which , user can write a query and then i will be executing that query on my server.
I am using the following MySQL docker image with the latest tag i.e. mysql:latest
https://hub.docker.com/_/mysql/
So i am runnig the docker image using this command
docker run -it --name some-mysql -e MYSQL_ROOT_PASSWORD=my-secret-pw -v /root/ServerCode/:/usercode mysql /bin/bash
My root/ServerCode directory contains a script which i want to use for running mysql server and user's query.
My script is
#!/bin/bash
set -e
/etc/init.d/mysqld start
It gives me error
bash: /etc/init.d/mysqld: No such file or directory
I have also tried using this
service mysqld start
It is also giving error
mysqld: unrecognized service
Edit:
#!/bin/bash
set -e
exec 1> $"/usercode/logfile.txt"
exec 2> $"/usercode/errors"
# These output and error files are in mounted folder which i check after running script
/etc/init.d/mysqld start // run sql server here
#here i want to run that query and then get out of conatiner `

The entyrypoint scipt only does the initdb if mysqld is the argument; in your case it sees bash and so skips the initdb and just runs bash with its arguments.
If you are just trying to run some setup scripts once mysql is running have you looked at /docker-entrypoint-initdb.d/?
Create a docker-compose.yml
version: '2'
services:
db:
image: mysql
container_name: mysql
restart: always
volumes:
- /var/db/startuphry/mysql:/var/lib/mysql
- ./conf/my.cnf:/etc/mysql/conf.d/settings.cnf
- ./conf/docker-entrypoint-initdb.d:/docker-entrypoint-initdb.d
environment:
- MYSQL_ROOT_PASSWORD=${MYSQL_ROOT_PASSWORD}
- MYSQL_DATABASE=${MYSQL_DATABASE}
- MYSQL_USER=${MYSQL_USER}
- MYSQL_PASSWORD=${MYSQL_PASSWORD}
ports:
- "${MYSQL_PORT}:3306"
Create a conf folder add the my.cnf file to it
[mysqld]
local-infile=0
Create folder docker-entrypoint-initdb.d inside conf folder and all sql files inside this folder
Tree looks likes this
|____docker-compose.yml
|____conf
|___my.cnf
|___docker-entrypoint-initdb.d
|___one.sql
|___two.sql
You can put any .sh files or .sql files in there and they will be run/imported before the mysql service is available outside the container.

Try running the "/etc/init.d/mysqld start" inside the mysql docker container.
/root/server is a host machine path . Mysql has been installed in container not in the host machine. Please run the "/etc/init.d/mysqld start " not in the host machine.
