ERROR 2003 (HY000): Can't connect to MySQL server (111)
Please check your listenning ports with :
netstat -nat |grep :3306
If it show
tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN
Thats is ok for your remote connection.
But in this case i think you have
tcp 0 192.168.1.3:3306 0.0.0.0:* LISTEN
Thats is ok for your remote connection.You should also check your firewall (iptables if you centos/redhat)
services iptables stop
for testing or use :
iptables -A input -p tcp -i eth0 --dport 3306 -m state NEW,ESTABLISHED -j ACCEPTiptables -A output -p tcp -i eth0 --sport 3306 -m state NEW,ESTABLISHED -j ACCEPT
And another thing to check your grant permission for remote connection :
GRANT ALL ON *.* TO remoteUser@'remoteIpadress' IDENTIFIED BY 'my_password';
errno 111 is ECONNREFUSED, I suppose something is wrong with the router's DNAT.
It is also possible that your ISP is filtering that port.
Check that your remote host (i.e. the web hosting server you're trying to connect FROM) allows OUTGOING traffic on port 3306.
I saw the (100) error in this situation. I could connect from my PC/Mac, but not from my website. The MySQL instance was accessible via the internet, but my hosting company wasn't allowing my website to connect to the database on port 3306.
Once I asked my hosting company to open my web hosting account up to outgoing traffic on port 3306, my website could connect to my remote database.
