`# apt install nginx podman nodejs`
## Preparation
Create a new network for the database and wikijs
`$ podman network create wikijs`
## Database setup
`# podman pull docker://postgres`
```
# podman run -p 127.0.0.1:5432:5432 --name wikijsdb \
-e POSTGRES_PASSWORD=wikijs \
-e PGDATA=/var/lib/postgresql/data/pgdata \
-v /mnt/postgres/wikijsdb:/var/lib/postgresql/data \
-d docker.io/postgres
```
`# podman exec -it wikijsdb bash`
`# psql -U postgres`
Create database used by wikijs
`=# CREATE DATABASE wikijs;`
### Systemd Service
Generate the systems service file following the [podman guide](/linux/services/podman)
## Wiki.JS Setup
`$ cd /var`
`# wget https://github.com/Requarks/wiki/releases/download/(version)/wiki-js.tar.gz`
`# mkdir wiki`
`# tar xzf wiki-js.tar.gz -C ./wiki`
`$ cd ./wiki`
Move default config
`# mv config.sample.yml config.yml`
```

Don't forget to open permissions so the systemd service can run the server
`# useradd -m wiki`
`# chown wiki:wiki -R /var/wiki`
Run server directly:
`$ node server`
## Systemd service
Put this under `/etc/systemd/system/wiki.service`
```
[Unit]
Description=Wiki.js
After=network.target
Wants=container-wikijsdb.service
[Service]
Type=simple
ExecStart=/usr/bin/node server
Restart=always
# Consider creating a dedicated user for Wiki.js here:
#User=nobody
User=wiki
Environment=NODE_ENV=production
WorkingDirectory=/var/wiki
[Install]
WantedBy=multi-user.target
```
`# systemctl daemon-reload`
`# systemctl enable --now wiki`
## Nginx config
*Replace "IPV4" and "IPV6"*
```
server {
server_name DOMAIN_NAME;
# Security / XSS Mitigation Headers

add_header X-XSS-Protection "1; mode=block";

return 301 https://$host$request_uri;
}

}
```
Enable config
`# ln -s /etc/nginx/sites-available/(config) /etc/nginx/sites-enabled`
Restart nginx
`# systemctl restart nginx`
## Wiki Settings
### Storage with git
Create a home directory for the wiki user if you haven't used "-m" when creating the user.
**Make sure not to have a "/" after the directory you want for your user**
```
# mkdir /home/wiki
# chown wiki:wiki -R /home/wiki
# usermod -d /home/wiki wiki
```
Create ssh key as wiki user
`$ ssh-keygen -t ed25519 -C wiki`
- DB - PostgreSQL used as Search Engine
## Update Wiki
Download and install the latest release with these steps
`# systemctl stop wiki`
`$ cd /var`
`# wget https://github.com/Requarks/wiki/releases/download/(version)/wiki-js.tar.gz`
This is to ensure we have a known good version to go back to in case something goes wrong
`# mv wiki wiki-old`
`# mkdir wiki`
`# tar xzf wiki-js.tar.gz -C ./wiki`
`# cp wiki-old/config.yml wiki/`
`# chown wiki:wiki -R /var/wiki`
`# systemctl start wiki`
## Database Backup
`# podman exec (container name) pg_dump (database name) -U (database user) -F c > wikibackup.dump`
## Database Restore
**The wiki has to be installed fully, but not yet configured**
*Also works for transfering wiki from one server to another*
Stop the database and wiki
Drop the existing database and restore from the database
`# podman exec -it (container name) dropdb -U (database user) (database name)`
`# podman exec -it (container name) createdb -U (database user) (database name)`
`cat ~/wikibackup.dump | docker exec -i (container name) pg_restore -U (database user) -d (database name)`
Start the database and wiki again
