Openfire is a cross-platform java based free Instant Messaging server which implements the XAMPP (Jabber) protocol with extensions. It is very well suited as corporate instant messaging solution.
After I installed the Openfire, I could not login using the admin’s password while I am 100% sure that my password was correct. I believe it is a bug of Openfire.
Here is how I recoved the admin’s password.
1. Run Openfire Installation Wizard again:
cd /usr/share/openfire/conf
vi openfire.xml
Change the true to false
Run the Installation Wizard again, which is http://your_ip_address:9090/
2. Select MySQL as the Openfire’s database during the installation. You may still select HSQLDB instead of MySQL. Because I am not familiar with HSQLDB, I selected MySQL which is easy for me to reset admin’s password.
You need to create a new MySQL database and provide the related information in the installation wizard.
After you finished the installation wizard, you can go to next step.
3. Reset admin’s password in MySQL:
Login to MySQL and use openfire database. I use the command:
mysql -u root -p openfire
Display the password for the admin user with the query:
select password from ofUser where username = ‘admin’;
The encryptedPassword field is your admin’s password. Change the admin (or any other users) password by setting password field to chosen value and encryptedPassword field to null. For example here is the query to set the admin password to 123456:
update ofUser set password=’123456′, encryptedPassword = null where username =’admin’;
This will change the current admin password to 123456. Remember to change it to a different value after you login to the admin console. This will change your password to null and encryptedPassword to an encrypted string for added security purpose.
4. Restart the Openfire and Login again:
/etc/init.d/openfire restart
You have two options to install WordPress in Ubuntu 9.10. The first option is to download and install WordPress manually. If you are in a shared web hosting environment, you have to do this way.
The second option is to install it from the Ubuntu’s repository. If you are the root, you can just type:
apt-get install wordpress
Everything will be installed and configured automatically for you.
However, you need to change following configuration manually, otherwise the WordPress can only be visited at your local host, like http://localhost/wordpress/. If you visit it from network, like http://your_ip_address/wordpress, you will get an error.
3. Create MySQL Database
mysql -u root -p
mysql> CREATE DATABASE sugarcrm;
mysql> USE sugarcrm;
mysql> GRANT ALL PRIVILEGES ON sugarcrm.* TO sugarcrm@localhost IDENTIFIED BY ‘mypassword’;
DB Name: sugarcrm
DB User: sugarcrm
DB User Password: mypassword
DB Host: localhost
4. Run Installation Wizard at http://localhost/sugarcrm/
1) Set /etc/php5/apache2/php.ini to increase:
- PHP Memory Limit from 16M to 40M
memory_limit = 40M
- Upload File Size:
upload_max_filesize = 48M
2) Install cURL for the purpose of transferring data.
apt-get install php5-curl
3) Install IMAP Module: InboundEmail and Campaigns (Email) require the IMAP libraries. Neither will be functional.
apt-get install php5-imap
4) Create an empty .htacess file under the root directory of SugarCRM and chmod it to 777.
After hitting the “Install” button, the Wizard will create all tables in MySQL. If you selected the “Sample Data”, it will also create it for you. It will also write following data to the .htaccess file created by you.
When I upgraded the WordPress to 2.9.2 and enabled the Akismet plugin, I got 500 Internal Server Error. The reason is some WordPress 2.9.2 and some plugins need PHP 5. So, I solved the problem by adding Type and Handler for PHP 5 in the .htaccess file at the WordPress Root Directory.
