Thank you! That solved the libc* error messages, and now syslog is
working! However, it also relabeled my directories for virtual hosts and
now they are not working.

I've been using this command to set virtual hosts with selinux:

chcon -R system_u:object_r:httpd_sys_content_t /home/vhost1

Is this the correct way to do it?

Also mysql still doesn't want to start. Any suggestions here?
