Usage

To get started with Percona Server for MySQL promptly, this Quickstart guide emphasizes using Docker or installing with APT or YUM. Also you can follow along the Quickstart guide on the Percona website for more details.

Docker

Starting a Detached Container

Start a container with the --detached or -d option to run it in the background. In detached mode, the container exits when the main process used to run it exits.

Start a container named ps with the latest version of Percona Server for MySQL 8.3. This example sets the root password to root (not secure).

$ docker run -d \
  --name ps \
  -e MYSQL_ROOT_PASSWORD=root \
  cgr.dev/chainguard/percona-server:latest

By default, Docker pulls the image from Docker Hub if it is not available locally.

To view the container’s logs, use:

$ docker logs ps --follow

You can access the server when you see the "ready for connections" message in the log.

You can pass options with the docker run command. Example: Set UTF-8 as the default character set and collation for all databases.

$ docker run -d \
  --name ps \
  -e MYSQL_ROOT_PASSWORD=root \
  cgr.dev/chainguard/percona-server:latest \
  --character-set-server=utf8 \
  --collation-server=utf8_general_ci

Accessing the Percona Server Container

Use the docker exec command to get a shell inside the container. Example:

$ docker exec -it ps /bin/bash

For troubleshooting, the error log is located in /var/log/ or /var/log/mysql/, typically named error.log or mysqld.log.

View the error log with:

$ more /var/log/mysql/error.log

Accessing the Database

You can access the database using docker exec or the mysql command inside the container’s shell.

$ docker exec -ti ps mysql -uroot -proot

mysql: [Warning] Using a password on the command line interface can be insecure.
Welcome to the MySQL monitor.  Commands end with ; or \g.

You can also use the MySQL command-line client inside the container’s shell to access the database:

$ mysql -uroot -proot

mysql: [Warning] Using a password on the command line interface can be insecure.
Welcome to the MySQL monitor.  Commands end with ; or \g.
