Operating System & Droplet information
Ubuntu 14.04.3 x64
1GB Ram
30GB SSD Disk

Steps to reproduce the error
$ sudo apt-get update
$ sudo apt-get install mysql-server
$ sudo mysql_install_db
$ sudo mysql_secure_installation

After updating all packages and downloading/configuring required packages, I tried the following:

$ sudo nano /etc/mysql/my.cnf
Find the bind-address under [mysqld].

I changed the bind-address* to my second Droplet’s **Private Network Address. After that, I told MySQL to restart with the following command: sudo service mysql restart and I got the following reply:

mysql stop/waiting
start: Job failed to start

It does work fine when I edit the file back to it’s original settings (listening to 127.0.0.1 instead of a Public or Private Network Address).

I’ve also tried to clear log files, purge the system and re-install everything again (on three or four different Droplets). So far without any luck.

What am I doing wrong? Is this a known issue, maybe?

Articles that I’ve (tried) to follow:

https://www.digitalocean.com/community/tutorials/how-to-set-up-a-remote-database-to-optimize-site-performance-with-mysql

Various StackOverflow articles that had similar issues, but their solutions haven’t worked for me (purging the system, re-installing, etc.).

Thank you in advance.
