  • 40.7% indicated that they preferred to deploy servers virtually, 29.3% indicated they used virtualization whenever possible
  • The leading virtualization technology used by respondents was VMware that was in use by 79.3% of survey respondents who were using virtualization

20 Aug 10 Display Chinese Characters in WordPress

By default, Chinese characters do not work in WordPress if you didn’t originally setup your WordPress to handle it. To display or compose Chinese in your blog, you can change the WordPress database Collations to utf8_unicode_ci for all tables. If you have phpMyAdmin, you can manually change them one by one. However, it will take long time to fix all of them. Here is an easy way to change all Collations using script.

1. Create a file as: alter_mysql_tables.php

2. Copy and paste the following lines to the file and modify it using your own database connection

Download File: [download id="1"]
3. Save the file and upload to your ftp.
4. Run the script in browser: http://www.yourdomain.com/alter_mysql_tables.php
5. That’s all!

02 Aug 10 WordPress Permalinks

By default, WordPress uses URL with question mark and its post ID.  After enable Pretty Permalinks, all the posts give 404 error. At first, I thought it’s .htaccess problem, however this file was updated automatically after applied the changes. After searching Wordpress documents, I found that it also requires FollowSymLinks option and AllowOverride FileInfo directives in Apache configuration file. I never knew this since shared hosting server has those options enabled by default. On VPS server, I have to configure by myself.

vi /etc/httpd/conf/httpd.conf

# Each directory to which Apache has access can be configured with respect
# to which services and features are allowed and/or disabled in that
# directory (and its subdirectories).
