Because no one had better idea, I have restored my master server(virtual) from a backup witch is exactly a week old. I cant connect to a database from the slave to master, using I had solved this last week editing passwords in phpmyadmin, but I have changed many passwords and I dont know which one is necessary to connect from slave to master. Here is a screen from phpmyadmin. Today I have edited only: line 7 and 10. But its not working. Where: Line 3 - (ispcsrv2) is my slave server Line 4 - (ispcsrv2) is my slave server hostname(proxmox.mydomain.com) Line 7 - (ispcsrv2) is my slave server ip Line 10(second from the bottom) - my slave server hostname(proxmox.mydomain.com) No granted privileges for ispconfig,ispcsrv* is that ok? This one is like that: nano /etc/mysql/my.cnf - #bind-address = 127.0.0.1 Thank You In Advance.
