Moving MySQL directory on an Amazon EC2 machine
- by Traveling Tech Guy
I'm trying to have MySQL point to a directory on an EBS volume I mounted on my EC2 machine.
I took th following steps:
Stopped MySQL (/etc/init.d/mysqld stop) - successful
Created a MySQL directory on my volume, mounted on /vol (mkdir /vol/mysql)
Copied the contents of /var/lib/mysql to /vol/mysql (cp -R /var/lib/mysql /vol/mysql)
Chanded the owner and group of that directory to match the original (chown -R mysql:mysql /vol/mysql) - after this step, the 2 directories are identical.
Edited the /etc/my.cnf file (commented 2 original lines):
[mysqld]
#datadir=/var/lib/mysql
#socket=/var/lib/mysql/mysql.sock
datadir=/vol/mysql
socket=/vol/mysql/mysql.sock`
Started MySQL (/etc/init.d/mysqld start) - FAILED
The error file /var/log/mysqld.log contains the following lines:
100205 20:52:54 mysqld started
100205 20:52:54 InnoDB: Started; log sequence number 0 43665
100205 20:52:54 [Note] /usr/libexec/mysqld: ready for connections.
Version: '5.0.45' socket: '/vol/mysql/mysql.sock' port: 3306 Source distribution
No other errors are available.
What am I doing wrong?
Where can I find the error/s encountered by MySql?
If I restore the original lines, MySQL starts, leading me to believe it may be a permissions issue - but permissions are the same for both directories?
Thanks!
