# Using MySQL
|
|
|
|
Many applications depend on MySQL as their database, and you may
|
|
need it for your tests to run.
|
|
|
|
## Use MySQL with the Docker executor
|
|
|
|
If you want to use a MySQL container, you can use [GitLab Runner](../runners/README.md) with the Docker executor.
|
|
|
|
1. [Create CI/CD variables](../variables/README.md#create-a-custom-variable-in-the-ui) for your
|
|
MySQL database and password by going to **Settings > CI/CD**, expanding **Variables**,
|
|
and clicking **Add Variable**.
|
|
|
|
This example uses `$MYSQL_DB` and `$MYSQL_PASS` as the keys.
|
|
|
|
1. To specify a MySQL image, add the following to your `.gitlab-ci.yml` file:
|
|
|
|
```yaml
|
|
services:
|
|
- mysql:latest
|
|
```
|
|
|
|
- You can use any Docker image available on [Docker Hub](https://hub.docker.com/_/mysql/).
|
|
For example, to use MySQL 5.5, use `mysql:5.5`.
|
|
- The `mysql` image can accept environment variables. For more information, view
|
|
the [Docker Hub documentation](https://hub.docker.com/_/mysql/).
|
|
|
|
1. To include the database name and password, add the following to your `.gitlab-ci.yml` file:
|
|
|
|
```yaml
|
|
variables:
|
|
# Configure mysql environment variables (https://hub.docker.com/_/mysql/)
|
|
MYSQL_DATABASE: $MYSQL_DB
|
|
MYSQL_ROOT_PASSWORD: $MYSQL_PASS
|
|
```
|
|
|
|
The MySQL container uses `MYSQL_DATABASE` and `MYSQL_ROOT_PASSWORD` to connect to the database.
|
|
Pass these values by using variables (`$MYSQL_DB` and `$MYSQL_PASS`),
|
|
[rather than calling them directly](https://gitlab.com/gitlab-org/gitlab/-/issues/30178).
|
|
|
|
1. Configure your application to use the database, for example:
|
|
|
|
```yaml
|
|
Host: mysql
|
|
User: runner
|
|
Password: <your_mysql_password>
|
|
Database: <your_mysql_database>
|
|
```
|
|
|
|
## Use MySQL with the Shell executor
|
|
|
|
You can also use MySQL on manually-configured servers that use
|
|
GitLab Runner with the Shell executor.
|
|
|
|
1. Install the MySQL server:
|
|
|
|
```shell
|
|
sudo apt-get install -y mysql-server mysql-client libmysqlclient-dev
|
|
```
|
|
|
|
1. Choose a MySQL root password and type it twice when asked.
|
|
|
|
NOTE:
|
|
As a security measure, you can run `mysql_secure_installation` to
|
|
remove anonymous users, drop the test database, and disable remote logins by
|
|
the root user.
|
|
|
|
1. Create a user by logging in to MySQL as root:
|
|
|
|
```shell
|
|
mysql -u root -p
|
|
```
|
|
|
|
1. Create a user (in this case, `runner`) that is used by your
|
|
application. Change `$password` in the command to a strong password.
|
|
|
|
At the `mysql>` prompt, type:
|
|
|
|
```sql
|
|
CREATE USER 'runner'@'localhost' IDENTIFIED BY '$password';
|
|
```
|
|
|
|
1. Create the database:
|
|
|
|
```sql
|
|
CREATE DATABASE IF NOT EXISTS `<your_mysql_database>` DEFAULT CHARACTER SET `utf8` \
|
|
COLLATE `utf8_unicode_ci`;
|
|
```
|
|
|
|
1. Grant the necessary permissions on the database:
|
|
|
|
```sql
|
|
GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, CREATE TEMPORARY TABLES, DROP, INDEX, ALTER, LOCK TABLES ON `<your_mysql_database>`.* TO 'runner'@'localhost';
|
|
```
|
|
|
|
1. If all went well, you can quit the database session:
|
|
|
|
```shell
|
|
\q
|
|
```
|
|
|
|
1. Connect to the newly-created database to check that everything is
|
|
in place:
|
|
|
|
```shell
|
|
mysql -u runner -p -D <your_mysql_database>
|
|
```
|
|
|
|
1. Configure your application to use the database, for example:
|
|
|
|
```shell
|
|
Host: localhost
|
|
User: runner
|
|
Password: $password
|
|
Database: <your_mysql_database>
|
|
```
|
|
|
|
## Example project
|
|
|
|
To view a MySQL example, create a fork of this [sample project](https://gitlab.com/gitlab-examples/mysql).
|
|
This project uses publicly-available [shared runners](../runners/README.md) on [GitLab.com](https://gitlab.com).
|
|
Update the README.md file, commit your changes, and view the CI/CD pipeline to see it in action.
