Installing WordPress-MU on your Heroehost hosting account
Hello all,
Many of our clients are asking how to install wordpress-mu with sub-domains support. here is a very simple way for it in easy steps.
Step:1 Download Latest version of WordPress-MU from WordPress-MU website . Create a database with MySQL database wizard available in cPanel and note down the databasename, username and password.
Step-2 You can upload the files in 2ways.One way is you can upload the downloaded archive directly to your hosting space and can uncompress there another way is to extract the files in to a folder in your computer and FTP them to your hosting space. The upload should be done only in to /public_html/ folder (this is default folder).All the files and folders like 'wp-admin' etc., should be in root folder that is /publich_html/ folder.
Step-3 Make the necessary files writable and proceed with installation by pointing your browser to domain.Select the option "Sub domains (like blog1.example.com)" as shown in image below
Now fill the database details of the MySQL database we created earlier in Step-1.Leave the Server address untocued (by default it will be yourdomain.com). Fill your blog title and email and click on install.If you get error saying that .htaccess file already exists,Open the file manager from control panel and delete the already existing .htaccess file and realod the page it should show your administrator username and admin password note them.
Step-4 Subdomains will not work by default you need to add a subdomain to make all the subdomains work.Go to the 'subdomains' from cpanel and add a subdomain with host as '*' and direcotry as /public_html/.
