Installing CMS Made Simple [version 2.2.8+]
You need to follow these steps to install CMS Made Simple (CMSMS):
1. Download the installation files archive (expanded version) and its checksum file from the official vendor site. CMS Made Simple can be obtained from:
http://www.cmsmadesimple.org/
2. Once you have downloaded the archive that contains the installation, you need to upload it to your hosting account. You do not need to upload the checksum file.
You can either extract all the files from the downloaded archive and upload them, or you can upload the archive and use the web hosting Control Panel's File Manager to extract the package.
The best way to upload big files or multiple files is via FTP. If you are not sure how to upload the files, please check the Uploading files section from our online documentation.
If you are installing the application in your main domain, or in a subdomain, you may need to delete the default index.php file first. You can do this either via FTP or through your web hosting Control Panel's File Manager.
3. Create a new MySQL database and user for the CMSMS application. For security reasons, MySQL databases and users can be created only through the hosting Control Panel. Detailed instructions on the process are available in our Creating a MySQL database/user article.
Once you have the database and MySQL user created, you should associate the MySQL user with the database by following the instructions from our Associating a MySQL user with a database article. Unless you have a reason to do otherwise, you can select all available privileges for the new MySQL user.
4. By default, the time zone for CMSMS will be set to the server's time zone. If you wish to change it, please refer to our Changing the server timezone in PHP scripts article.
You should also enable output buffering via a PHP configuration file (php.ini) in your hosting account. Example values you can add a php.ini file are:
output_buffering = on
output_buffering = 4096
You can learn more on how to change various PHP settings in our Changing PHP Settings article.
