解决Bitnami MySQL连接问题

Question

I have setup Bitnami MySQL service on Azure. The VM is up and I am able to connect to the VM through ssh like ssh username@HOSTNAME:

I am able to login to the mysql from the prompt like

mysql -uroot -pSOMEPASS >

Meanwhile I am able to connect this mysql service from a remote host: mysql -uroot -pPASS -hxxx.xxx.xx.xx

The following error is what I received

ERROr 2003 (HY000); Can't connect to MySQL Server on xxx.xxx.xx.xx

I tried commenting out the the bind-address in the /opt/bitnami/mysql/my.cnf

and tried giving the value for bind-address as 0:0:0:0 & also removing the variable.

To ensure the mysql port is up or not I gave the following comamnd

netstat -tln

tcp6 0 0 :::3306 :::* LISTEN

the above results mean port is and listening

In terms of file permission related, I entered the following ones

chmod 777 /opt/bitnami/mysql/tmp chmod 755 /opt/bitnami/mysql/data chown -R root:root /opt/bitnami/mysq/tmp chown mysql:root /opt/bitnami/mysql/data/ sudo chmod 777 /opt/bitnami/mysql/tmp sudo chmod 755 /opt/bitnami/mysql/data sudo chown root:root /opt/bitnami/mysql/tmp sudo chown mysql:root /opt/bitnami/mysql/data

Also added skip-grant-tables in my.cnf

I also performed the following the query in the mysql

GRANT ALL ON . to root@'%' IDENTIFIED BY 'SOMEPASSWORD';

Any hint would be greatly appreciated. Thanks in advance

To connect to your Bitnami MySQL, follow these steps:

1.Make sure your Azure VM have a public IP address .

2.Open port 3306 to NSG inbound rules : 3.Edit the file /opt/bitnami/mysql/my.cnf and comment out this line by placing a hash(#) symbol at the beginning, save it.

#bind-address=127.0.0.1

4.At the server console, allow remote access to the MySQL database server using the MySQL command line client. Use the following command, remembering to replace PASSWORD with the application password from the first step:

/opt/bitnami/mysql/bin/mysql -u root -p -e "grant all privileges on *.* to 'root'@'%' identified by 'PASSWORD' with grant option";

5. Restart the MySQL server:

sudo /opt/bitnami/ctlscript.sh restart mysql

Now, you can remote connect to your bitnami mysql.

Here is my result:

Hope this helps.
