I know there are several threads about this, but I've tried everything and am at my wit's end- I would just like to be able to connect to a MySQL database hosted on EC2.
I have added port 3306 to the security group for the instance on EC2.
I have removed bind_address (skip-networking is no longer used by default) from the my.cnf file and restarted MySQL. I have also alternatively tried bind_address=(external IP, it starts with 54.) and bind_address=0.0.0.0.
UFW status is inactive.
On the server, running:
mysql -u remote-user -p -h MY_EXTERNAL_IP
works! But it doesn't work from my client, I get:
`ERROR 2003 (HY000): Can't connect to MySQL server on 'MY_EXTERNAL_IP' (111)`
I created my current MySQL user with:
GRANT USAGE ON *.* TO 'remote-user'@'localhost' IDENTIFIED BY 'password';
GRANT USAGE ON *.* TO 'remote-user'@'%' IDENTIFIED BY 'password';
I even ran:
sudo iptables -P INPUT ACCEPT
sudo iptables -A INPUT -i eth0 -p tcp -m tcp --dport 3306 -j ACCEPT
sudo iptables -I INPUT -i eth0 -p tcp -m tcp --dport 3306 -j ACCEPT
Telnet doesn't connect:
echo X | telnet -e X MY_EXTERNAL_IP 3306
echo X | telnet -e X MY_EXTERNAL_IP 3306
telnet: Unable to connect to remote host: Connection refused
But it does connect to the ssh port:
Trying 54.221.103.104...
Connected to 54.221.103.104.
and netstat -a | grep 'mysql'
netstat -a | grep 'mysql'
gives:
tcp 0 0 *:mysql *:* LISTEN
unix 2 [ ACC ] STREAM LISTENING 20762 /var/run/mysqld/mysqld.sock
Please, I'm at my wit's end. I just can't figure out what's wrong with this, I've been working on it for hours.
comment line in /etc/mysql/my.cnf
that says: bind-address 127.0.0.1
this is the reason, I spend some 20-30 mins to figure out why it happens with disabled firewall :) this line makes Your server to listen only to calls from localhost on this port. Ofcourse You have to restart mysql service after this.
change the bind address in /etc/mysql/my.cnf from 127.0.0.1 to 0.0.0.0 has solved my issue and I was able to TELNET remotely on port 3306 without issues.
Also make sure your mysql user is not set only as a localhost mysql user and has the proper privileges.
