Can't connect to remote MySQL server with error 61 - mysql

Question

When I tried to connect the remote MySQL server by using command line mysql -h <remote-ip> -u any_existing_users -p or any other mysql client such as phpmyadmin, it didn't work and the error hint was
ERROR 2003 (HY000) Can't connect to MySQL server on '<remote-ip>' (61)
But, when I tried ssh <remote-ip> and connected the MySQL locally by mysql -u root -p, there is no problem.
Here is part of the user table(SELECT User, Host FROM mysql.user;):
+------------------+----------------+
| User | Host |
+------------------+----------------+
| root | % |
| other_users | <remote-ip> |
| root | localhost |
+------------------+----------------+
Here is the iptable:
Chain INPUT (policy ACCEPT)
num target prot opt source destination
1 RH-Firewall-1-INPUT all -- 0.0.0.0/0 0.0.0.0/0
Chain FORWARD (policy ACCEPT)
num target prot opt source destination
1 RH-Firewall-1-INPUT all -- 0.0.0.0/0 0.0.0.0/0
Chain OUTPUT (policy ACCEPT)

Chain RH-Firewall-1-INPUT (2 references)

7 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:631
8 ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 state RELATED,ESTABLISHED
9 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:22
10 REJECT all -- 0.0.0.0/0 0.0.0.0/0 reject-with icmp-host-prohibited
11 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:3306
So, what's the problem?

Answer 1

Check if your mysql server is listening on a socket with netstat:
netstat -tulpen
and search for 3306.
If not or if only on localhost, check my.cnf and search the bind-address line and change it to:
bind-address = 0.0.0.0
then restart the server and try again.

Answer 2

Check status:
netstat -tulpen
Modify your configuration:
nano /etc/mysql/my.cnf
# Edit:
bind-address = 0.0.0.0
Enter mysql and give privileges:
mysql -umyuser -pmypassword
# Run:
GRANT ALL PRIVILEGES ON *.* TO 'myuser'#'%'IDENTIFIED BY 'mypassword' WITH GRANT OPTION;
FLUSH PRIVILEGES;
exit
Restart mysql
/etc/init.d/mysql restart

Answer 3

With MySql 5.7 they changed files so bind-address is now in:
/etc/mysql/mysql.conf.d/mysqld.cnf
instead of:
/etc/mysql/my.cnf

Answer 4

If you run MAMP, do not forget to allow access (mySQL panel, check "Allow network access to MySQL")

Answer 5

I had this problem just after installing Centos 7 on a server. I could´t access to it through Mysql Workbench in a remote computer.
The problem was in the firewall configuration. Eventually, the solution came when doing:
sudo firewall-cmd --zone=public --permanent --add-service=mysql
And then, restart the firewall:
sudo systemctl restart firewalld

Answer 6

Take a look at the "Causes of Access-Denied Errors" from MySQL.
http://dev.mysql.com/doc/refman/5.1/en/access-denied.html
Possibile is there a failed configuration on your server or a other program is using the same port? Or is the server bind on "127.0.0.1"? Try changing the the my.cnf file.

Answer 7

It can be a problem related to firewall or try this:
GO to Server Admin -> MySQL -> Settings -> check: Allow Network Connections
Then restart MySQL

Answer 8

For MacOS:
mysql -uroot -p
mysql> use mysql;
# View user's host
mysql> select 'host' from user where user='root';
# Update host to '%'
mysql> update user set host='%' where user='root';
mysql> flush privileges;
mysql> quit
vim /usr/local/etc/my.cnf
# Default Homebrew MySQL server config
[mysqld]
bind-address = 0.0.0.0
# Restart and reconnect MySQL
mysql.server restart
mysql -uroot -h0.0.0.0 -p
