Prerequisites

Recommended EC2 instance type is i3.xlarge.

1. Install OpenJDK 11 by running the following command:
   sudo yum install java-11-amazon-corretto

2. Install wget by running the following command:
   yum install wget

3. Verify the installation by running the following command:
   java -version

4. Set map count within /etc/sysctl.conf file by adding the following line:
   vm.max_map_count=262144

5. Increase ulimit value and test system settings

   To change the file descriptor setting, edit the file /etc/sysctl.conf.
   Add line fs.file-max=100000 to it.

   To apply the changes :
   sysctl -p

   To change the ulimit setting, edit the file /etc/security/limits.conf and set the hard and soft limits:
   * soft nofile 100000
* hard nofile 100000

   After this value is changed please reboot the server.
   reboot

   Test the settings using the following command:
   ulimit -a

   To check the current open file descriptor limit:
   more /proc/sys/fs/file-max
   OR sysctl -a | grep fs.file-max

   To find out how many file descriptors are currently being used:
   more /proc/sys/fs/file-nr

   To find out how many files are currently open:
   lsof | wc -l

Installation

1. Please login as root using sudo su if you are not the root user.

2. Create a SearchBlox user
   sudo adduser searchblox
sudo passwd searchblox

3. SearchBlox has to be installed in /opt folder, so change directory to /opt
   cd /opt

4. Download SearchBlox rpm package
   sudo wget https://d2fco3ozzrfhhd.cloudfront.net/v10.2/searchblox-10.2-0.noarch.rpm

5. Install the rpm package
   sudo rpm -ivh searchblox-10.2-0.noarch.rpm

6. Change permission for the following folders
   sudo chown -R searchblox:searchblox /opt/searchblox
sudo chmod -R 755 /opt/searchblox/bin
sudo chmod -R 755 /opt/searchblox/elasticsearch/bin
sudo chmod -R 755 /opt/searchblox/analytics
sudo chmod -R 755 /opt/searchblox/logs
