Hi All,
Hopefully a simple question to answer. I am going to be setting up multiple Apache web servers behind a F5 load balancer and need to share the documentRoot out to all the servers. I have a dedicated SAN which I want to use and I've been searching to find a concrete document that states if its ok to use an iscsi drive or NFS mounted to all web servers but haven't seen anything concrete to say thats the normal or best practice way to setup that environment. My main concern is writing to the file at the same etc.

Can someone advise what they do for multiple web servers?

Thanks

Dears,
I want to create script to rename multiple file names from unix date to date for example
filename_1421907815_department.txt
rename to
filename_2015_01_22_08_23_department.txt

I am trying to code a python script that does:- Using root account logs into multiple servers provided in a list. Check the OS type e.g. Linux, Solaris, HP-UX and Windows. Depending on the OS type it updates the name servers and options in /etc/resolv.conf. The update is done from a list that is also provided.

Any help is much appreciated.

Hello,

My job is having me get back into Linux. It has been awhile since I messed with it. My company releases Software that runs on Linux. As such, when we release a new version of the software, we have it packaged with the entire Linux OS. As such, when it is sent to our clients, they install, and then have to reconfigure, the Host Name, IP Address, Netmask, and Gateway. Our test environment consists of over ten different Linux boxes and configurations. To make life easier for me, I have written a shell script allowing me a menu to change all of these and to also enable or disable the gateway and how to set/change the localadm password.

I want the script available to users to be able to run it anytime they need to. It works great. I would like to add one more thing to this. I want to be able to run the script automatically on the very first boot after the installation. The script is set up where you have to log in as root to run it. So here is the process I want to happen:

Install Disk
System starts up for very first time after install
Automatically logs in as root and runs script
Exits as root.

I realize Linux will only do what I tell it to. How do I tell it to do this?

I am taking a Linux class and am doing horribly, I just do not understand Linux. Can anyone please tell me how to create a shell script containing the `echo`, `whoami`, `groups`, and `pwd` commands?

I can do these as individual commands but cannot figure out how to do this in a shell script and get the output to produce output similar to the following:

You a
root
You are a member of the following groups:
root bin daemon sys adm disk wheel
Your current working directory is:
/tmp

My hair is getting thinner and grayer because of this.. Please help!
