Wiki.js is an elegant looking wiki based on Markdown. It supports LDAP and many more authentication mechanisms. In this guide we describe how to install Wiki.js on Ubuntu 16.04.

Prerequisites

An Ubuntu 16.04 instance.

Install curl, Node.js v8.x and build-essential:

# apt -y install curl
# curl -sL https://deb.nodesource.com/setup_8.x | bash -
# apt -y install nodejs build-essential

Install MongoDB v3.4

# apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 0C49F3730359A14518585931BC711F9BA15703C6
# echo "deb [ arch=amd64,arm64 ] http://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.4 multiverse" | tee /etc/apt/sources.list.d/mongodb-org-3.4.list
# apt update
# apt -y install mongodb-org

Start MongoDB:

# systemctl start mongodb

Enable MongoDB at startup:

# systemctl enable mongodb

Install git

The version that comes with Ubuntu 16.04 fills the minimum requirements so there is no need to install it from upstream.

# apt -y install git

Install Wiki.js

# mkdir /srv/wiki.js
# cd /srv/wiki.js
# npm install wiki.js@latest

You will get this message:

> Browse to http://your-server:3000/ to configure your wiki! (Replaced your-server with the hostname or IP of your server!)
▐   ⠂    ▌ I'll wait until you're done ;)

Do as the message says. Let the wizard wait until we are done, and open another shell to work with.

Setup nginx

Install Nginx:

# apt -y install nginx

Create this VirtualHost configuration (/etc/nginx/sites-available/wiki.example.com.conf):

server {
    listen      [::]:80 ipv6only=off;
    server_name wiki.example.com;
    return      301 https://$server_name$request_uri;
}
server {
    listen 443 ssl http2;
    listen [::]:443 ssl http2;
    server_name  wiki.example.com;

    ssl_session_timeout 1d;
    ssl_session_cache shared:SSL:50m;
    ssl_session_tickets off;

    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers "EECDH+ECDSA+AESGCM EECDH+aRSA+AESGCM EECDH+ECDSA+SHA384 EECDH+ECDSA+SHA256 EECDH+aRSA+SHA384 EECDH+aRSA+SHA256 EECDH EDH+aRSA !RC4 !aNULL !eNULL !LOW !3DES !MD5 !EXP !PSK !SRP !DSS";
    ssl_prefer_server_ciphers on;

    ssl_certificate /etc/nginx/ssl/wiki.example.com.crt;
    ssl_certificate_key /etc/nginx/ssl/wiki.example.com.key;
    ssl_trusted_certificate /etc/nginx/ssl/CA.crt;

    location / {
        proxy_set_header Host $http_host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_pass http://127.0.0.1:3000;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_next_upstream error timeout http_502 http_503 http_504;
    }
}

Enable the wiki.example.com VirtualHost:

# cd /etc/nginx/sites-enabled/
# ln -s ../sites-available/wiki.example.com.conf
# unlink default

Restart Nginx:

# systemctl restart nginx

Configure Wiki.js

After the installation you will be asked if you wish to run the configuration wizard. Select this and continue:

Yes, run configuration wizard on port 3000 (recommended)

Now browse to http://wiki.example.com/ and follow the installation wizard:

Welcome!: Start
System Check (if all good): Continue
General:
- Site title: ExampleWiki
- Host: https://wiki.example.com
- Port: 3000
- Site UI Language: English
- Public Access: Not selected
- Press: Continue
Important Considerations: Continue
Database: mongodb://localhost:27017/wiki
Database Check: Continue:
Paths:
- Local Data Path: ./data
- Local Repository Path: ./repo
Git Repository: Skip this step
Git Repository Check: Continue
Administrator Account
- Administrator Email: admin@example.com
- Password: MySecretCombination
- ConfirmPassword: MySecretCombination
Finalizing: Start

Enable Wiki.js on startup

# npm install -g pm2
# pm2 startup
# pm2 save

Setup LDAP

This is an optional step for those wishing to integrate Wiki.js in their LDAP infrastructure.

Trust CUT IST ISSUING CA

Connect to the LDAP (AD) server and get all certificates:

openssl s_client -showcerts -connect dcs03ist00.lim.tepak.int:636 | tee ldap.log

Hit ‘Ctrl-C’ to end the command.

The certificate with the ID ‘1’ in ldap.log is the ISSUING CA certificate. Extract the CUT IST ISSUING CA certificate and save it in cut_issuing_ca.crt:

Verify the certificate with:

openssl x509 -text -in cut_issuing_ca.crt

Add the CUT ISSUING CA in the trusted chain of the system:

cp cut_issuing_ca.crt /usr/local/share/ca-certificates/
update-ca-certificates

Configure LDAP for Wiki.js

Make these changes in /srv/wiki.js/config.yml:

  ldap:
    enabled: true
    url: 'ldap://ldap.example.com:389'
    bindDn: 'cn=wiki,ou=dsa,dc=example,dc=com'
    bindCredentials: 'MyLDAPCredentials'
    searchBase: 'ou=people,dc=example,dc=com'
    searchFilter: '(uid={{username}})'
    tlsEnabled: true
    tlsCertPath: '/etc/ssl/certs/ca-certificates.crt'

Give Access permissions to authenticated users

Visit the Admin URL:

https://wiki.example.com/admin

Click on ‘Users’. You will get a list of users. You can give ‘Read and Write’ access to them from the ‘Access Rights’ field and you can upgrade them to ‘Global Administrators’ from the ‘Role Override’ field.

NOTE: For LDAP the users need to login first before they are allowed to write.

Enjoy your newly created Wiki!
