[Koha-devel] RE: [Koha] Changed IP - Can't connect to mysql server

[Robert Linebaugh]

The my.cnf is located at /etc/my.cnf.   Below is the info.  I don’t seem to have a bind-address.

 

[mysqld]

datadir=/var/lib/mysql

socket=/var/lib/mysql/mysql.sock

# Default to using old password format for compatibility with mysql 3.x

# clients (those using the mysqlclient10 compatibility package).

old_passwords=1

 

[mysql.server]

user=mysql

basedir=/var/lib

 

[mysqld_safe]

err-log=/var/log/mysqld.log

pid-file=/var/run/mysqld/mysqld.pid

I did not use the GRANT ALL ON command on the mysql server.  I assume this command has to be performed on the mysql server and the @server should be the Koha server?  (ex.  GRANT ALL ON koha.* to address@hidden  ) I probably need to know the mysql root password that I’ve been reading about?

 

I’m not sure how to connect to the mysql server with the commandline mysql client from the koha server.

Hi Rob, 

 

your mysql server isnt configured to allow remote connections.

 

these are *nix examples, but you get the gist...

You can google for more info.

 

 

1) edit your mysql conf file , change your bind-address value from 127.0.0.1 to your server's IP

 

server$ vi /etc/mysql/my.cnf

# bind-address       = 127.0.0.1    

bind-address        = 10.0.254.4

 

------------

2) restart your mysqld

server$ /etc/init.d/mysql restart

 

------------

3)  connect to server from the client....

client $ mysql -u kohaadmin -h 10.0.254.4  -p    koha

Your MySQL connection id is 8

Server version: 5.0.32-Debian_7etch5 Debian etch distribution

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

Mason.

Can you connect to the mysql server with the commandline mysql client on the koha server ?

Hi Robert,

 

Try these tests too...

 

To test your networking, try a telnet to the remote mysql box...

$ telnet 10.0.250.4 3306

 

If that works, hit it with the mysql client...

$ mysql -u kohaadmin –h 10.0.250.4  –p'mypassword' koha

 

Cheers, Mason.
