Upgrading WordPress from 2.3.3 to 2.5

1. Backup all the relevant wordpress files.

mv blog blog.bkp

2. Backup your MySQL database

mysqldump crucialu_blog > crucialu_blog.sql

3. Upgrade necessary plugins and once done, login to WordPress as admin and deactivate all plugins.

Dashboard ->> Plugins ->> Deactivate All Plugins

4. Download the latest wordpress.

wget http://wordpress.org/latest.tar.gz

5. Untar the file and rename it to /blog

mv wordpress blog

6. Copy the wp-config.php from the backup

cp -p blog.bkp/wp-config.php blog/

7. Take the URL http://www.crucial.com.au/blog/wp-admin/upgrade.php and Click on “Upgrade WordPress”

Click on “Continue” to complete the upgrade.

8. Copy the custom files /folder from backup to the new installation folder

cp -rpf blog.bkp/wp-content/* blog/wp-content/

9. Login to wordpress as admin and Activate the required plugins.

Dashboard ->> Plugins

After upgrade, if you are getting a blank screen while accessing the site, you might have forgotten to copy the themes and templates. Go to step 8 in that case.

LVM: pvcreate /dev/sda4 gives error Device /dev/sda4 not found (or ignored by filtering).

If you are using the pvcreate command something like this:

pvcreate /dev/sda4

And it gives an error like this:

Device /dev/sda4 not found (or ignored by filtering).

This can sometimes be resolved by rebooting the server (if the LVM partition was just created, and the server has not yet been rebooted).
