Question

I installed MySQL on a linux system. I have running Debian. I can access mysql with local ip address through command on local system as well as remotly

./mysql -h 192.168.1.151 -u root -pabcd

. Now I added a host(192.168.1.152), and I can not use AddedHost to connect remotely from other machine, i have given all privileges to this host as

grant all on *.* to 'root'@'192.168.1.152' identified by 'abcd';

but i failed to connect locally as well as remotly.
i got the error when i execute command

./mysql -h 192.168.1.152 -u root -pabcd

error 2003 (hy000) can’t connect to mysql server on ‘192.168.1.152’ (111)

please help me out to sort out this issue.
Thanks

Answer 1

This error means, from here(FAQ)-

• There is no MySQL server running at the specified host

• Connection to the MySQL server is not allowed using TCP-IP. Check the ‘skip-networking’ setting in the MySQL configuration file (my.ini
  on Windows, my.cnf on Unix/Linux). It shall be commented out like
  ‘#skip-networking’. If it is not commented out, then do it and restart
  the MySQL server for the change to take effect. SQLyog needs to
  connect using TCP-IP.

• Some networking issue prevents connection. It could be a network malconfiguration or a firewall issue. We have experienced sometimes
  that some firewalls (ZoneAlarm in particular) is blocking TCP-IP
  connections even if it claims to be disabled. Most often it will help
  to uninstall and reinstall the firewall.

• When trying to connect to a MySQL server at an ISP this error message often indicates that direct connection to MySQL has been
  blocked. You must then use HTTP-tunneling or SSH-tunneling to connect.
