Reconfigure the database¶

1. Drop the databases if they exist
    
   

   mysql -h localhost -u root
   
   show databases;
   

   
   If you see:
   projectdb
   leginondb
   

   drop database projectdb;
   drop database leginondb;
   

2. Create the databases
   

   create database projectdb;
   create database leginondb;
   

3. Download config.php and put it in /var/www/html/myamiweb
    
4. Change the permission of the config file
   

   chmod 777 /var/www/html/myamiweb/config.php
   

5. Point your web browser to http://localhost/myamiweb/setup
   1. The database username is root
   2. There is no database password. Leave this field empty.
   3. Click Next on each page without making any changes.
   4. Eventually, you will see a button to Create Web Tools Config. Click on this button, and ignore the Apache User error.
   5. Click on the DB Initialization button.
   6. Click Next.
   7. Click Next to insert default values.
   8. You will need to enter information for the Adminstrator Appion user. You may enter any password and your email address.
   9. When this completes, you may start using Appion, or may continue with the following steps to insert a sample project into the database which can be used for processing with Appion.
       
6. Delete the sample images folder
   

   cd /myamiImages/leginon
   rm -rf sample
   

7. Point your browser to the following url but first replace your_root_password with the root password of your CentOS installation.
   

   http://localhost/myamiweb/setup/autoInstallSetup.php?password=your_root_password
   

8. When this script completes, you will be redirected to the Appion and Leginon home page.
