Setting It Up

Now you should be ready to get to the meat of the matter. Please review the steps below:

1. Launch an Instance

I) Go to community AMI and check Red Hat

II) Select a Red Hat 7.x Image

2. Select Instance Type

Select a m4.xlarge Image

3. Request a Spot

4. Create three volumes

  1. Create a /dev/sdb volume of 55 GB
  2. Create a /dev/sdc volume of 8 GB

5. Add tags to your instance

6. Open Ports in your Security Group

  1. Open port 9000 - as this is the default port when installing ArcSight as a non-root user.
  2. Open port 443 for https - as this is the default port used when installing as a root user.
  3. Launch the instance and login.

7. Configuring the Instance : Create a directory called ArchSight

Navigate to your /opt directory and create a directory called arcsight.

8. Configuring the Instance (I)

Change the format of the volume with commands below:

  1. sudo mkfs.ext4 /dev/xvdb
  2. sudo mkfs.ext4 /dev/xvdc

9. Configuring the Instance (II)

Mount and change the etc/fstab

  1. sudo mount /dev/xvdb /opt/arcsight
  2. sudo mount /dev/xvdc /tmp
  3. Navigate to /etc/fstab

And add the below lines:

  1. /dev/xvdb /opt/arcsight ext4 defaults,nofail 0 2
  2. /dev/xvdc /tmp ext4 defaults,nofail 0 2

10. Configuring the Instance (III)

Editing logind.conf

  1. Navigate to /etc/systemd directory and open the logind.conf (Might need to be a sudo user).

Make sure the file has the following entry:

  1. RemoveIPC=No

If the entry for “RemoveIPC“ is not there, add it and equate it to “no”.

After making the changes, restart systemd-logind service with the below command:

  1. systemctl restart systemd-logind.service

11. Configuring the Instance (IV)

Create a user and a user group

  1. Login into your EC2 instance
  2. Run the commands shown in the image to create a user called ‘arcsight' and a usergroup called 'arcsight’

12. Configuring the Instance (V)

Grant permission

  1. Grant permission for the ArcSight user for /opt/arcsight directory

13. Configuring the Instance (VI)

Unset Display

  1. Since we are installing ArcSight in the console mode:

14. Configuring the Instance (VII)

Increasing user process limit and max. no. of process files

  1. Navigate to the /etc/security/limits.d folder
  2. Open the 20.nproc.conf file as sudoer in an editor
  3. Erase the existing records in the file
  4. Add the records as shown in the image and save the file
  5. Reboot the instance

And run the command ulimit -a

It should print the output as below:

  1. open files 65536
  2. max user processes 10240
