To enable log rotation on CentOS 6, run the following

cat <<'END_OF_TEXT' >> /etc/logrotate.d/httpd
/var/log/httpd/*log {
    missingok
    notifempty
    sharedscripts
    daily
    rotate 7
    postrotate
        /sbin/service httpd reload > /var/log/httpd/rotate 2>&1 || true
    endscript
    compress
}
END_OF_TEXT

By default symbolic links may not work on Apache on CentOS. Assuming the symlink we are considering points to /example, then use the following command. This will add the appropriate SELinux context to the /exampledirectory and all its contents

chcon -Rv --type=httpd_sys_content_t /example

Replace

httpd_sys_content_t

with

public_content_t

if you want it to work with ftp as well.

When using an xauth, you may get this error

ERROR = /usr/bin/xauth:  timeout in locking authority file /home/username/.Xauthority

The solution is to fix the SELinux permissions

chcon unconfined_u:object_r:user_home_dir_t:s0 /home/username

Run this command to allow Perl to connect to Database server while still having SELinux enabled.
