Troubleshooting
Error: Missing Dependency: libpq.so.3 is needed by package ossec-hids-server
This occurs on CentOS4 systems using the CentOSPlus repository, and updating to OSSEC 2.0. It can be resolved with:
yum install postgresql-devel
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
