Upgrade WordPress 2.7 in 3 Simple Steps

WordPress version 2.7 has been released and can be upgraded easily using UNIX / Linux shell prompt. A few assumptions:

  1. WordPress database name: wptheosblog
  2. WordPress directory name: /var/www/html/theos.in
  3. WordPress domain name: theos.in
  4. Operating system: Linux
WARNING! If you are not comfortable with UNIX shell prompt (IF YOU ARE new to a UNIX/Linux os), please follow traditional way of upgrading wordpress and DO NOT use the three Steps described here.

Since I use wordpress as CMS for 2-3 different websites, upgrading wordpress is an essential task for me. Upgrading wordpress from shell prompt is the easiest thing.

Howto update wordpress

Please note that if you are not comfortable with UNIX shell prompt (IF YOU ARE new to UNIX/Linux), please follow traditional way of upgrading wordpress and DO NOT use following instructions ;)

Step # 1: Backup existing database and wordpress directory

Type the following commands at shell prompt:

$ mkdir /backup/wp/28nov2006
$ mysqldump -u user -p WP-DATABASENAME > /backup/wp/28nov2006/blog.db.sql
$ tar -zcvf /backup/wp/28nov2006.tar.gz /var/www/html/blog

Step # 2: Download latest wordpress CMS

$ cd /tmp
$ wget http://wordpress.org/latest.zip
$ unzip latest.zip

Step # 3: Overwrite all new files

$ cd /var/www/html/blog
$ cp -avr /tmp/wordpress/* .
$ rm -rf /tmp/wordpress /tmp/latest.zip

Open a browser and run update script such as http://yourblog.com/wp-admin/upgrade.php

And you are done. Thanks to UNIX shell access. It just took less than 1 minute!!! Replace path names and database name with actual values.

In case, if something goes wrong, you can always restore old database and files from /backup/wp/28nov2006 directory.
