Preface
Goal: Setting-up LAMP stack with Artix OpenRC. Configure MariaDB.
MariaDB is MySQL compatible. So we use a lot of mysql reference here. Such as data path, service name and such.
Install MariaDB Packages
Just like any other stack we start with installing. Instead of ready to use docker, this time we install in system.
- mariadb
- mariadb-openrc
❯ sudo pacman -S mariadb mariadb-openrc

:: Processing package changes...
What we need to care about is, whether the we should do additional task manually, or just leave it. Such as manual database setup.
(1/2) installing mariadb
:: You need to initialize the MariaDB data directory prior to starting
the service. This can be done with mariadb-install-db command, e.g.:
mariadb-install-db --user=mysql --basedir=/usr --datadir=/var/lib/mysql
Optional dependencies for mariadb
cracklib: for cracklib plugin [installed]
curl: for ha_s3 plugin [installed]
galera: for MariaDB cluster with Galera WSREP
judy: for Open Query GRAPH (OQGraph) computation
engine
perl-dbd-mariadb: for mariadb-hotcopy,
mariadb-convert-table-format and
mariadb-setpermission
python-mysqlclient: for myrocks_hotbackup
xz: lzma provider [installed]
And so init related stuff. Depend on the policy, some system require us to do stuff manually, for flexibility reason.
(2/2) installing mariadb-openrc

==> Add a service to runlevel:
rc-update add <service> <runlevel>
==> Start/stop/restart a service:
rc-service <service> <start/stop/restart>
Setup Database
This is my favorite. We actually can setup the database, with our own parameter.
❯ sudo mariadb-install-db \
--user=mysql \
--basedir=/usr \
--datadir=/var/lib/mysqlInstalling MariaDB/MySQL system tables in '/var/lib/mysql' ...
OK
To start mariadbd at boot time you have to copy
support-files/mariadb.service to the right place for your system
The complete response is here. I guess you understand the reason why, I don’t dump them all in this article.
If your database is already exist, the command would response differently.
Running Service
Init handling is a must have knowledge in linux system. Init diversity is optional, depend on your taste, and distribution flavour. For OpenRC we have this two commands:
- rc-update,
- rc-service
We need to set that the mysql started automatically, at the default runlevel. We can reach this runlevel default after boot, or depend on your init management.
❯ sudo rc-update add mysql default
* service mysql added to runlevel default
Of course the mysql is still not running, unless we have booted the system. That is why we have to start manually.
❯ sudo rc-service mysql status
ERROR! MariaDB is not runningNow let’s get it started.
❯ sudo rc-service mysql start
Starting MariaDB.230321 17:40:51 mysqld_safe Logging to '/var/lib/mysql/andalan.err'.
230321 17:40:51 mysqld_safe Starting mariadbd daemon with databases from /var/lib/mysql
SUCCESS!
❯ sudo rc-service mysql status
SUCCESS! MariaDB running (32473)
We are sooo.. up and running…
Hard Reset
If you don’t have any necessary data, you can reset you database.
Sometimes it is necessary for new system. Just to make sure that a process is repeatable.
❯ sudo rc-service mysql stop
Shutting down MariaDB. SUCCESS!
❯ sudo rm -rf /var/lib/mysql/
If you start, you will have an error. Of course, because we have no setup yet.
You will have to do setup procedure again.
❯ sudo mariadb-install-db \
--user=mysql \
--basedir=/usr \
--datadir=/var/lib/mysqlSocks Issue
I was once encounter this sock issue.
❯ mariadb
ERROR 2002 (HY000): Can't connect to local server through socket '/run/mysqld/mysqld.sock' (2)
All I need to do is restart the service to get the sock.
No need to logout or even reboot.
Version
Test
How I would I know that MariaDB works in my machine?
If everything fine, your MariaDB should show the versionn.
❯ mariadb --version
mariadb Ver 15.1 Distrib 10.11.2-MariaDB, for Linux (x86_64) using readline 5.1
We are ready.
What is Next 🤔?
Now it is time to examine SQL in MariaDB.
