OSSEC 2.0.0-0.090205 test build this update addresses mysql issues mentioned in the troubleshooting section

Troubleshooting

Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)

This is a known problem in versions of OSSEC 1.6.1 and lower. Currently to fix this an upgrade to a newer version is required:


Step 1) Upgrade to a CVS snapshot (1.99 or higher)

 yum --enablerepo=asl-2.0-testing upgrade ossec-hids

Step 2) Update ASL policy

 asl -s -f

Step 3) Drop the existing tortix database

 mysql -u admin -p`cat /etc/psa/.psa.shadow`
 drop database tortix;

Step 4) Create a new database, and select it

 create database tortix;
 use tortix;
 quit

Step 5) Create the new OSSEC database

 mysql -u admin -p`cat /etc/psa/.psa.shadow` tortix < /var/ossec/etc/mysql/mysql.schema

Step 6) restart ossec

 /etc/init.d/ossec-hids restart
