Install WikiJS on Ubuntu 20.04

Linux Ubuntu

What is WikiJS

WikiJS is well-known wiki-based engine. Its popularity is growing today due to such advantages as open-source code which supported by big developers community, easy-to-install, small system requirements and well-readable documents markup by default.

Necessary server specs

To install WikiJS you need:

  • Server with at least 1Gb RAM and 10Gb disk space;
  • Actual Linux OS (Ubuntu 20.04 in this article);
  • Privileged user access;
  • Domain name with A-records, "pointed" to the server's IP (optional).

Installation procedure

WikiJS setup process is very simple, possible for everybody. Just do followed step-by-step instruction:

  • Authorize on the server, update exist software and reboot machine to apply changes;
apt-get update; apt upgrade -y && reboot

  • Set up utilities to earn other necessary tools and scripts;
apt install wget curl -y

pic2

 

  • Earn, then setup nodejs;
curl -fsSL https://deb.nodesource.com/setup_16.x | sudo -E bash - && apt -y install nodejs

pic3

IMPORTANT: NodeJS v18 is not compatible with WikiJS now! You shuldn't use it.

  • Add additional repository and install database service e.g. MariaDB;
apt install -y software-properties-common; curl -LsS https://r.mariadb.com/downloads/mariadb_repo_setup | /bin/bash; apt-get update; apt install -y mariadb-server mariadb-client

  • Enable, then launch MariaDB, then check the status;
systemctl enable mariadb; service mariadb start

systemctl status mariadb

pic5

  • Make necessary database service settings. Set password you want, other settings - up to you, default is enough;
mysql_secure_installation

pic6

  • For convenient experience in future, create authentication data and put section with your credentials inside;
nano ~/.my.cnf

 

[client]
user=root
password=<your_password>

pic7

  • Enter into Mariadb console, create database and user for WikiJS;
create database <database_name>;
create user '<database_username>'@'localhost' identified by '<your_database_password>';
grant all on <database_name>.* to '<database_username>'@'localhost' with grant option;
flush privileges;
exit

pic8

  • The best way is run WikiJS engine in dedicated userspace. Let's create account and directory:
adduser --home /wikijs --disabled-password wikijs

pic9

  • Switch user to wikijs, download and unpack the archive;
su wikijs

cd ~; wget https://github.com/Requarks/wiki/releases/latest/download/wiki-js.tar.gz; tar -xf *.tar.gz

pic10

  • Rename template config and edit it. Set database type and credentials;
cp config.sample.yml config.yml; nano config.yml

pic11

  • Return back to the root console and create wiki service via text editor. Just run this command:
exit

nano /etc/systemd/system/wiki.service

pic12

  • Insert code below into the file and save it;

[Unit]
Description=Wiki
After=network.target

[Service]
Type=simple
ExecStart=/usr/bin/node server
Restart=always

User=wikijs
Environment=NODE_ENV=production
WorkingDirectory=/wikijs

[Install]
WantedBy=multi-user.target

pic13

  • Then create start.sh script with followed content:

#/bin/bash

sleep 5
/usr/bin/node /wikijs/server

  • Reload system configuration, enable and run service you've made. Then check service status;
systemctl daemon-reload; systemctl enable wiki; systemctl start wiki

service wiki status
