How do I get my site working again? (Ubuntu 16.04)

Linode Staff

My site is not working from yesterday.
Initially I had a "Error establishing a database connection" error.
I logged into and did a reboot.
After that I am getting a site can't be reached error.

Below are some information that could help.

 [email protected]:~# iptables -S

[email protected]:~# netstat -tulpn
Active Internet connections (only servers)

The netstat command shows that you only have SSH listening on port 22. For your site to be working, you'd likely also want either nginx or apache2 to be listening on port 80. If you have a database, you'll want to see mySQL listening on port 3306.

I'd recommend starting each of these, and enabling them so that they automatically start on boot. If you are using nginx instead, simply replace apache2 with nginx in the commands below.

sudo systemctl restart apache2
sudo systemctl enable apache2
sudo systemctl restart mysql
sudo systemctl enable mysql
