Wetty : Ubuntu, and Let's Encrypt (letsencrypt)

Ubuntu doesn't use upstart anymore, but systemd instead, so /usr/local/lib/node_modules/wetty/bin/wetty.conf is useless.

Solution : https://github.com/krishnasrinivas/wetty/issues/44#issuecomment-179102722

Find wetty.js :

sudo updatedb
locate wetty.js

Create the file : /etc/systemd/system/wetty.service (and change the path of wetty.js if needed)

[Unit]
Description=Wetty - Web TTY
After=network.target auditd.service

[Service]
ExecStart=/usr/local/lib/node_modules/wetty/bin/wetty.js -p 3000 --sslkey /etc/letsencrypt/live/my.domain.tld/privkey.pem --sslcert /etc/letsencrypt/live/my.domain.tld/cert.pem
Restart=always

[Install]
WantedBy=multi-user.target

Then

sudo service wetty restart
