h1. Database Server Setup to allow connection from the instruments 

 You need to do is even if you have used autoinstaller    so that computers controlling the instruments (microscope/camera) can connect to the database 

 h2. Bind mysqld to its IP address to allow tcp connection to it. 

 h3. Edit /etc/my.cnf search for *skip-networking* and make sure it is commented out like this: 

 <pre> 
 #skip-networking 
 </pre> 
 Add the address the database is bound to after that line 
 <pre> 
 #skip-networking 
 bind-address=your.ip.address.number 
 </pre> 
 for example, 192.168.0.1 in a local network 

 h3. Restart mysqld 

 
 For CentOS, Fedora 
 <pre> 
 sudo /etc/init.d/mysqld restart 
 </pre> 
 or 
 <pre> 
 sudo /sbin/service mysqld restart 
 </pre> 

 h3. 10 Create remote user 

 Create and grant privileges to the usr_object for the databases on the hosts involved.    See MySQL Reference Manual for details. 

 You can set hosts on a particular subnet by only specify the network number portion such as '192.168' and use wild card for the host number portion to give '192.168.%.%' as the global host allowing connection. 
 If appropriate, you can also use domaian name with wild care i.e., '%.mydomain.edu' 

 At the mysql prompt execute the following commands: 
 <pre> 
 CREATE USER usr_object@'192.168.%.%' IDENTIFIED BY 'YOUR PASSWORD'; 
 GRANT ALTER, CREATE, INSERT, SELECT, UPDATE ON leginondb.* TO usr_object@'192.168.%.%'; 
 GRANT ALTER, CREATE, INSERT, SELECT, UPDATE ON projectdb.* TO usr_object@'192.168.%.%'; 
 </pre> 

 h3. Change localhost database user to usr_object if autoinstaller was used. 

 Autoinstaller does not create usr_object user on the localhost but use root user for database connection.     You may want to make change at this time. 

 At the mysql prompt execute the following commands: 
 <pre> 
 CREATE USER usr_object@'localhost' IDENTIFIED BY 'YOUR PASSWORD'; 
 GRANT ALTER, CREATE, INSERT, SELECT, UPDATE ON leginondb.* TO usr_object@'localhost'; 
 GRANT ALTER, CREATE, INSERT, SELECT, UPDATE ON projectdb.* TO usr_object@'localhost'; 
 </pre>
