Installation of SearchBlox in Ubuntu

Prerequisites:

• Install OpenJDK 11 on Linux prior to installing SearchBlox, and ensure it uses the default Java runtime. You can install OpenJDK 11 by running the following command:
  sudo apt install openjdk-11-jdk -y
• The below command can be used if the above does not work. Refer ubuntu forums for more help in installation of java 11
  sudo add-apt-repository ppa:openjdk-r/ppa && sudo apt-get update -q && sudo apt install -y openjdk-11-jdk
• Verify the installation by giving the command
  java -version

Steps for Installation

• Please login as root using sudo su if you are not the root user or install using sudo commands as below.
• Create a SearchBlox user by giving the necessary details

  sudo adduser searchblox
  

• SearchBlox has to be installed in /opt folder, so change directory to /opt

  cd /opt
  

• Download SearchBlox debain package

  sudo wget https://d2fco3ozzrfhhd.cloudfront.net/v9.1/searchblox_9.1-0_all.deb
  

• Install the debian package

  sudo dpkg -i searchblox_9.1-0_all.deb
  

• Change permission for few folders

  sudo chown -R searchblox:searchblox /opt/searchblox
  sudo chmod -R 777 /opt/searchblox/logs
  sudo chmod -R 777 /opt/searchblox/elasticsearch/logs
  sudo chmod -R 777 /opt/searchblox/bin
  

• Increase the map count to run Elasticsearch without issues

  sysctl -w vm.max_map_count=262144
  

  Elasticsearch also requires the ability to create many memory-mapped areas. The maximum map count check checks that the kernel allows a process to have at least 262,144 memory-mapped areas and is enforced on Linux only. To pass the maximum map count check, you must configure vm.max_map_count via sysctl to be at least 262144.
• Go to start.ini and give port 8080 at line number 143
• Run/start Elasticsearch and SearchBlox services

  systemctl start sbelastic
  systemctl start searchblox
  

• To stop Elasticsearch and SearchBlox use the commands below

  systemctl stop sbelastic
  systemctl stop searchblox
  

Steps to Uninstall/Remove SearchBlox

To uninstall SearchBlox, please use the below command:
apt-get remove searchblox

• Go to http://localhost:8080/searchblox/admin/main.jsp in your browser, accept the license agreement
  • Give the username as admin
  • You will see a temp password displayed the first time you go to the login page, after accepting the license agreement. Use the temp password to log in, then store or change the password for future login.

• By default, there will be one HTTP collection with the root URL http://www.cnn.com, which can be updated if required. You can index a collection by clicking the index button from the dashboard or the Index sub-tab.
• Click on the DashBoard sub-tab under Collections to view the indexing status.
• SearchBlox will run with a free license, by default, which allows you to use one collection only. To add another collection, delete the existing one and create another.
• Go to http://localhost:8080/searchblox/search.jsp or http://localhost:8080/searchblox/plugin/index.html to start searching.

Disk Encryption

1. Installation of cryptsetup
   for Ubuntu:
   # sudo apt-get install cryptsetup
2. LUKS Format disk
   Note: while formatting the disk we have to give some password
   # cryptsetup luksFormat /dev/sdb

3. Luks open
   Note: We have to use the password created earlier while formatting the disk.
   # cryptsetup luksOpen /dev/sda data

4. Create a filesystem
   #mkfs -t ext4 /dev/mapper/data

5. Mounting the new file system at /opt
   # mount /dev/mapper/data /opt
6. To get UUID
   #blkid /dev/mapper/data

7. We need to add the UUID into /etc/fstab like this and save it
   Note: We need to add the UUID into etc/fstab file

• TO close encryption
  /#cryptsetup luksClose /dev/mapper/data
• To open encryption
  /# cryptsetup luksOpen /dev/mapper/data
