## Server
Pulsar comes with build-in [Titan-II](https://github.com/YGGverse/titan-II) server implementation.
It's especially useful for [Yggdrasil](https://github.com/yggdrasil-network/yggdrasil-go) users, who wish to host their feeds using plain IPv6 `0200::/7` addresses without domain in `CN` record. Build-in server contain this feature implemented from the box.
For NEX protocol users, here is the [next](https://github.com/YGGverse/next) server solution!
### Setup
* `cd Pulsar` - navigate to the project folder
* `composer update` - download server dependencies with Composer
* `mkdir server/127.0.0.1` - init server location (you can define any other destination, `server` just git ignored)
* `cp example/host.json server/127.0.0.1/host.json` - copy configuration example to the destination folder
* `cd server/127.0.0.1` - navigate to server folder created and generate new self-signed certificate
On example above, certificate could be generated with following command:
```
openssl req -x509 -newkey rsa:4096 -keyout key.rsa -out cert.pem -days 365 -nodes -subj "/CN=127.0.0.1"
```
* _tip: for IPv6 address, just skip square brackets from `CN` value_
### Launch
* `php src/server.php server/127.0.0.1` - supported relative or absolute paths (for systemd service)
Open `gemini://127.0.0.1` in [Gemini browser](https://github.com/kr1sp1n/awesome-gemini#clients)!
### Autostart
Launch server as `systemd` service
Following example means you have Pulsar installed in home directory of `pulsar` user (`useradd -m pulsar`)
1. `sudo nano /etc/systemd/system/pulsar.service` - create new service file by following example:
``` /etc/systemd/system/pulsar.service
[Unit]
After=network.target
[Service]
Type=simple
User=pulsar
ExecStart=/usr/bin/php /home/pulsar/Pulsar/src/server.php /home/pulsar/Pulsar/server/127.0.0.1
StandardOutput=file:/home/pulsar/Pulsar/server/127.0.0.1/debug.log
StandardError=file:/home/pulsar/Pulsar/server/127.0.0.1/error.log
Restart=on-failure
[Install]
WantedBy=multi-user.target
```
2. `sudo systemctl daemon-reload` - reload systemd configuration
3. `sudo systemctl enable pulsar` - enable Pulsar service on system startup
4. `sudo systemctl start pulsar` - start Pulsar server
