Tried to add a header image to the blog. The image upload function worked fine but after the image was uploaded, WordPress asked to crop the image. Clicking on ‘Crop and Publish’ gives the error:
Image could not be processed. Please go back and try again.
Turns out you need an image manipulation tool called ‘gd’ to make WordPress header crop work. It is a module of php. Installation of gd:
# yum install php-gd
Had to restart apache and now header crop works!
My WordPress blog has been successfully installed.
Now, I want to run the blog under a sub-domain i.e. http://blog.domain.com instead of http://host.domain.com/blog.
Let’s see how this can be done.
Initial googling points to apache and mod_rewrite. Let’s read more.
Oops, further googling shows that this can be done without using URL rewrites. Just use the built-in apache virtual hosts feature by adding the following to the config file (/etc/httpd/conf/httpd.conf in CentOS):
NameVirtualHost *:80
<VirtualHost *:80>
ServerAdmin webmaster@blog.domain.com
DocumentRoot /path/to/wordpress/directory
ServerName blog.domain.com
ErrorLog logs/blog.domain.com-error_log
CustomLog logs/blog.domain.com-access_log common
</VirtualHost>
And.. voila! Not really. After doing this and restarting the apache service, http://blog.domain.com throws out a 404 error.
It turns out you need to change the WordPress working directory to the new URL via Settings>General before moving the files and implementing the virtual host. After that everything is OK.
