Create database for OpenDocMan

Log in to mysql as root user:

mysql -u root -p

Create a database and user for OpenDocMan. For example, here I am going to create database called “opendocmandb” and database user called “opendocmanuser” respectively. Change these values as your liking.

Type 'help;' or 'h' for help. Type 'c' to clear the current input statement.

mysql> create database opendocmandb;
Query OK, 1 row affected (0.03 sec)

mysql> GRANT ALL ON opendocmandb.* TO opendocmanuser@localhost IDENTIFIED BY 'centos';

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

mysql> exit

Adjust SELinux to avoid “403 forbidden error” while installing OpenDocMan. To do that, run the following commands from the Terminal:

setsebool -P httpd_enable_homedirs true
chcon -R -t httpd_sys_content_t /var/www/html/opendocman/

Download OpenDocMan

Download the latest version from this link.


Unzip and move the opendocman folder to your apache root folder.

mv opendocman- /var/www/html/opendocman

Create a folder outside of your public html folder that will contain your data files. This will be your “dataDir” folder in the config.

mkdir /var/www/odm_data/

Make sure the permissions and ownership of the data folder will allow for the web server to write to it.

chown apache:apache /var/www/odm_data/
chmod -R ugo+w /var/www/odm_data/

Make sure there is a templates_c folder, and the templates_c folder is writable. If the folder doesn’t exists, create it.

chmod -R ugo+w /var/www/html/opendocman/templates_c/

Begin Installation

Open up your browser and navigate to URL http://ip-address/opendocman. The following screen should appear.

Click on Create Configuration File link.

define('DB_HOST', 'localhost');

 * Prefix to append to each table name in the database (ex. odm_ would make the tables
 * named "odm_users", "odm_data" etc. Leave this set to the default if you want to keep
 * it the way it was. If you do change this to a different value, make sure it is either
 * a clean-install, or you manually go through and re-name the database tables to match.
 * @DEFAULT 'odm_'
 * @ARG String
$GLOBALS['CONFIG']['db_prefix'] = 'odm_';


/** Absolute path to the OpenDocMan directory. */
if ( !defined('ABSPATH') )
    define('ABSPATH', dirname(__FILE__) . '/');

Save and close the file. Then click Proceed to the installer button in the previous wizard.
