Hi
I need to check for a process running on multiple machines and if its not running, to send me an email.
I also want to give the list of machines as a separate text file i.e
checkprocess.pl "process name" "IPlist.txt"
Is there anything like this available. All the machines have the same user and use the same ssh keys..
So what the above does is ssh into your remote computer and it restarts apache on the remote computer. As you can see, it's a very simple script.
So, lets say you want to ssh into a list of servers (the list of servers are in servers.txt)
#!/bin/bash
SERVERS=`cat servers.txt | awk '{print $1}'`
for server in $SERVERS; do
echo "I'm logging into $server"; ssh $server "(echo "Hello, I'm inside")"; done
exit 0
Afraid to tell you, but for that piece it's going to be a lot more scripting for sure. What I would do is run 'ps -ef | grep httpd | grep -v grep' on the remote computer and save the success of that command to a variable. Then implement an IF function to check if it was successful or not, if not, then execute the mail command.
