Java

Installation

The latest OpenJDK

sudo pacman -S --needed jdk-openjdk openjdk-doc openjdk-src

OpenJDK 17

sudo pacman -S --needed jdk17-openjdk openjdk17-doc openjdk17-src

OpenJDK 11

sudo pacman -S --needed jdk11-openjdk openjdk11-doc openjdk11-src

OpenJDK 8

sudo pacman -S --needed jre8-openjdk-headless jre8-openjdk jdk8-openjdk openjdk8-doc openjdk8-src

VisualVM

sudo pacman -S --needed visualvm

For other versions, like Oracle and Zulu, you will have to do the installation manually. Download the desired version and unpack it in /usr/lib/jvm:

sudo tar -xvzf jdk-17.0.2_linux-x64_bin.tar.gz -C /usr/lib/jvm

Setting the default Java version

The helper script archlinux-java provides such functionalities:

archlinux-java <COMMAND>
COMMAND: status List installed Java environments and enabled one get Return the short name of the Java environment set as default set <JAVA_ENV> Force <JAVA_ENV> as default unset Unset current default Java environment fix Fix an invalid/broken default Java environment configuration

List compatible Java environments installed


archlinux-java status

Changing the default Java version

sudo archlinux-java set <java_version_name>

Unsetting the default Java environment

There should be no need to unset a Java environment as packages providing them should take care of this. Still, should you want to do so, just use command unset:

sudo archlinux-java unset

Fixing the default Java environment

If an invalid Java environment link is set, calling the archlinux-java fix command tries to fix it. Also note that if no default Java environment is set, this will look for valid versions and try to set it for you. Officially supported package “OpenJDK 8” will be considered first in this order, then other installed environments.

sudo archlinux-java fix

Kotlin

sudo pacman -S --needed kotlin ktlint

MySQL - MySQL Workbench

To install MySQL, choose MariaDB:

sudo pacman -S --needed mysql-workbench

Verify the installation:

mysqld --version

Enable and start the MySQL service:

sudo systemctl enable --now mysqld

If the following error is prompted:

Job for mariadb.service failed because the control process exited with error code. See "systemctl status mariadb.service" and "journalctl -xeu mariadb.service" for details.

Run the following command:

sudo mysql_install_db --user=mysql --basedir=/usr --datadir=/var/lib/mysql

The output should be similar to this:

Installing MariaDB/MySQL system tables in '/var/lib/mysql' ... OK To start mysqld at boot time you have to copy support-files/mysql.server to the right place for your system Two all-privilege accounts were created. One is root@localhost, it has no password, but you need to be system 'root' user to connect. Use, for example, sudo mysql The second is mysql@localhost, it has no password either, but you need to be the system 'mysql' user to connect. After connecting you can set the password, if you would need to be able to connect as any of these users with a password and without sudo See the MariaDB Knowledgebase at https://mariadb.com/kb You can start the MariaDB daemon with: cd '/usr' ; /usr/bin/mysqld_safe --datadir='/var/lib/mysql' You can test the MariaDB daemon with mysql-test-run.pl cd '/usr/mysql-test' ; perl mysql-test-run.pl Please report any problems at https://mariadb.org/jira The latest information about MariaDB is available at https://mariadb.org/. Consider joining MariaDB's strong and vibrant community: https://mariadb.org/get-involved/

Now, try enabling and starting the MySQL service again

Create a soft-link to the required library:

sudo ln -s /usr/lib64/libtinfo.so.6 /usr/lib64/libtinfo.so.5

Change root’s predefined password:

sudo mysql
UPDATE mysql.user SET Password=PASSWORD('MyNewPass') WHERE User='root';

Sometimes it can throw an error depending on the mysql version. When that happens, run the following:

ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass'; ALTER USER 'root'@'localhost' IDENTIFIED BY 'root'; FLUSH PRIVILEGES;

Upgrading MYSQL-MariaDB

Stop the service:

sudo systemctl stop mariadb sudo mysqld_safe --skip-grant-tables --skip-networking &

Open a new terminal window and run:

sudo mysql -u root
MariaDB [(none)]> use mysql
MariaDB [mysql]> flush privileges;
MariaDB [mysql]> ALTER USER 'root'@'localhost' IDENTIFIED BY 'the_password_i_want';
MariaDB [mysql]> exit

To kill the service, we need to find the PID:

ps -aux | grep mysql

Then kill the process, run this command for every PID listed:

kill -9 <PID>

Now, start the service:

sudo systemctl start mariadb

Source

PhpMyAdmin

Install the required packages:

sudo pacman -S --needed apache php libnotify phpmyadmin

Install plug-ins:

sudo pacman -S --needed php-apache php-cgi php-fpm php-gd php-embed php-intl php-redis php-snmp

Docker

Install Docker from the official repositories:

sudo pacman -S --needed docker docker-compose docker-scan

After installing Docker CE, start and enable the Docker Daemon.

sudo systemctl enable --now docker

Check the version of the Docker package to confirm it was successfully installed.

docker version

The output should be like this:

Client: Version: 20.10.22 API version: 1.41 Go version: go1.19.4 Git commit: 3a2c30b63a Built: Tue Dec 20 20:43:40 2022 OS/Arch: linux/amd64 Context: default Experimental: true Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get "http://%2Fvar%2Frun%2Fdocker.sock/v1.24/version": dial unix /var/run/docker.sock: connect: permission denied

Configuring Docker for Non-Root User

To enable your user account to access and manage docker without administrative privileges, we will add the account to the docker group.

newgrp docker
sudo usermod -aG docker $USER

Verify that your account is in the docker group:

id -nG

Try running a Docker command without sudo:

docker run hello-world

Linting

ESLint

sudo pacman -S --needed eslint

Prettier

sudo pacman -S --needed prettier prettyping

Stylelint

sudo pacman -S --needed stylelint
