configuration pages in the /etc/sysconfig/ha/web/secure/ directory but not
to the login and the help pages in /etc/sysconfig/ha/web/. To limit access to
this directory, create a .htaccess file in the /etc/sysconfig/ha/web/ directory
with order, allow, and deny lines identical to
/etc/sysconfig/ha/web/secure/.htaccess.
5. Turning on Packet Forwarding
In order for the LVS router to forward network packets properly to the real servers, each LVS
router node must have IP forwarding turned on in the kernel. Log in as root and change the line
which reads net.ipv4.ip_forward = 0 in /etc/sysctl.conf to the following:
net.ipv4.ip_forward = 1
The changes take effect when you reboot the system.
To check if IP forwarding is turned on, issue the following command as root:
/sbin/sysctl net.ipv4.ip_forward
If the above command returns a 1, then IP forwarding is enabled. If it returns a 0, then you can
turn it on manually using the following command:
/sbin/sysctl -w net.ipv4.ip_forward=1
6. Configuring Services on the Real Servers
If the real servers are Red Hat Enterprise Linux systems, set the appropriate server daemons to
activate at boot time. These daemons can include httpd for Web services or xinetd for FTP or
Telnet services.
It may also be useful to access the real servers remotely, so the sshd daemon should also be
installed and running.
