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>
