Starting points: (RE)Learning Linux commands
-
To see memory utilization, use free -m
-
To see disk space utilization use df -h
-
To see processes running in a nice, "live" table use top
-
CentOS on C@C and local
LinuxMint -
Which CentOS? Version matters a bit.
-
First thing to do with any CentOS...
yum -y install epel-release -
In CentOS you have YUM to make things easy. To install any software you just use...
yum install softwarename -
And to fully update your system just run....
yum update -
Be sure to install sysstat (System Stats) and htop (Horizontal TOP? Honestly, no idea what it stands for.)
yum -y install sysstat htop -
Once you have sysstat installed and it has sat around for ten minutes or more you will start to get details in your sar reports. This is one of the most important tools in your Linux arsenal. Once it has sat around you can see all kinds of details as to how it has been running....

yum -y install sysstat htopFrom http://hisham.hm/htop/index.php?page=faq:
What does the 'h' in 'htop' stand for?
Well, the short explanation is a little obvious: the "h" stands for "Hisham", my name.
The long explanation is that what inspired me to write htop was pinfo, an improved man and info reader that adds lots of features (in my machines 'man' is an alias to 'pinfo -m'). It was written by a guy called Przemek Borys. Since 'pinfo' was "a better info" and he named it "pinfo" ("Przemek's Info"), I decided to try to make "a better top" so I called it "htop" ("Hisham's top"). So yes, it is after my own name, but it's also a homage to another nice piece of software!

And of course the uptime command is super handy.
-bash-4.2$ uptime 14:39:39 up 6 days, 16:17, 1 user, load average: 0.27, 0.16, 0.15 -
Yum -
So one of the goals is to have ManageEngine running. I've uploaded the .bin file, WHile I know I didn't need to.. it's done..would it be
yum - y install (filename)?

While I think YUM has a local installation option, I don't think it will work with bin files.

A bin is a binary, like a Windows installer. It's not an RPM, which is an installation file. To install a binary, on any OS, just run it.

Not sure why that quoted three time...I feel I hear Foghorn Leghorn's voice here... "No no no son,.. your don't it all wrong..."
-
@g.jacobse did you make it executable? Chmod +x file.bin
then run it as ./file.bin -
should read:
./ManageEngine_ServiceDesk_Plus_64bit.binYou may also have to do chmod +x filename.

You are attempting to use a relative path, but the file is not in your path so it can't find it.

yum -y install epel-releaseI completely disagree with this statement because it implies that the EPEL is required. Most of my servers are CentOS 7 minimal and do not have EPEL.
There is NEVER a reason to always add stuff. There are often good reason for most servers, but there is never ALWAYS a reason.
In fact Scott, this is completely contrary to your constant preaching that people should always do things because they are needed and not because they just should because some random internet person said so.f
