Hi, there, I have two droplet (vlife-portal & vlife-data ) with the same configuration. vlife-portal have a SSL.
Within both mysql.user, I have set up root@‘private IP’ and grant them related privileges.
And I followed the tutorial in the community to set up master & slave mysql, I tried to make vlife-portal as master and the other as slave. But after I start the slave, I find that I cant connect to vlife-portal.
Then I tested on vlife-portal in my terminal, I can connect to vlife-data’s Mysql directly. However, when I on the vlife-data, I cant connect to vlife-portal.
iptables / firewalls are not enabled. No bind-address in my.cnf. I tried bind-address to 0.0.0.0 still not work.
**Error msg: ** ERROR 2003 (HY000): Can’t connect to MySQL server on ‘private IP’ (110)
Could you please give me an hand on this? Thanks.

Hi @cetetek
Okay, so you actually have a firewall rule that specifically blocks MySQL:
And I don’t see MySQL listening on the port, but only on a socket, so maybe you have the
skip-networkingdefined somewhere in the configuration.@cetetek
If you’re unable to connect on the private IP, it’s most likely due to MySQL not being bound to it. You may need to explicitly bind to it using:
Where
PRIVATE_IPis the private network IP for your Droplet. Once you bind MySQL to a private IP, you need to create a new user that uses the connecting servers private IP.…
For example, let’s say that the MySQL servers private IP is 11.22.33.44 and the connecting servers IP is 22.33.44.55.
You’d set:
and then create a new user using the connecting servers private IP:
You’d sub out
dbname,dbuser, anddbpasswordwith your own values.Hi @cetetek Can you run
sudo lsof -iTCP -sTCP:LISTEN -Pon the data server?
