Setting up haproxy and varnish with reference to the configuration from these sites:
And finally can access plone on the server. But when I check the haproxy status, only client1 can be accessed. All other clients were down with general socket error, permission denied. Googling a bit I finally found out it was due to SELinux. Refer to this page:
With the solution from that page, I installed policycoreutils-python and tried to run the command given:
semanage port --add --type http_port_t --proto tcp 8081
But that command failed with the error that the port was already defined. When I looked it up using:
semanage port -l | grep 8081
It belonged to some other type (transproxy_port_t). When I tried to delete the type using:
semanage port -d -t transpro…
When I first initially tried it, the installer cannot detect any local hard disk to install to. After much googling found out that it was because a certain driver for the Smart Array Controller is no longer available on Centos 7. To allow for use of the new driver on old hardware, you need to enable the option. Once the DVD has booted and on the first menu screen, highlight the first option and then press tab which would bring you to a command line where you can add additional parameters to boot. Add the following parameters:
And then press enter to boot. You should now be able to install as you wish.
After installation, on the first boot, make sure at the menu, press 'e' to edit the parameters and add them again. Then once booted, go to /boot/grub2/grub.cfg to permanently add the parameters to the menu.

I have been suffering from sleep apnea for quite a few years already. It started to show when I was still with OSCC some 6 years back when I would sometimes "accidentally" sleep at my cubicle. Early on I just dismissed it as because I was growing fat (we ate a lot at OSCC.. :P and I barely went anywhere except my cubicle) and also because of babies. Oh babies.. those cute little things that keeps you awake at night so that they can be so cute and charming when your friends and relatives come over the next day. So it was dismissed. Later on I got more and more used to sleeping at work, started associating it with my lack of motivation and sometimes feeling of downright depression. And I kept growing fatter and fatter, which I assumed was the reason why I was getting more and more tired.
But then around 2 years ago a friend of mine suggested maybe I've got sleep apnea. And a few other people suggested I go to a sleep clinic and all that. Put it off for quite a while. Until…
