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 (
- 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?
