  3. Install wget using the following command:
    sudo apt-get update
    sudo apt-get install wget

  4. Increase the map count with the following command
    sysctl -w vm.max_map_count=262144
    set this permanently in /etc/sysctl.conf by adding the following line:
    vm.max_map_count=262144

  5. Increase ulimit value and validate 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 that enable the pam_limits as followings:

    Edit the file /etc/pam.d/common-session and add the following line:
    session required pam_limits.so

    Reboot the server for the changes to take effect:
    reboot

    Check the ulimit settings by running the following commands:
    ulimit -a
    ulimit -Sn # Check soft limit
    ulimit -Hn # Check hard limit

Please confirm the message "Started Successfully" is shown in the log. In case of any errors, this log will provide additional information for troubleshooting.

🚧

SearchBlox Admin Console Access using IP Address or Domain Name

  • You can use your IP instead of localhost in the URL to access the SearchBlox Admin Console.
  • If a domain name is mapped to the IP address, you can use the domain name:
    https://exampledomain:port/searchblox/admin/main.jsp
    https://exampledomain:port/searchblox/plugin/index.html

Change SearchBlox Server Port

SearchBlox Server runs on port 8080 by default.

You can change the port by following the steps below:

  1. Stop SearchBlox

  2. Edit the file /opt/searchblox/start.ini at line number 163 as follows:
    jetty.http.port=8080

  3. Start SearchBlox

If it is not possible to run SearchBlox in a port less than 1024 since SearchBlox runs as a non-root user, you can enable port forwarding if required using :
iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 8080

Uninstall

Run the following command to uninstall or remove SearchBlox:

apt-get remove searchblox

Disk Encryption

🚧

Additional Disk is required for 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

WARNING!
========
This will overwrite data on /dev/sdb irrevocably.
Are you sure? (Type uppercase yes): YES
Enter LUKS passphrase:
Verify passphrase:
  1. Luks open
    Note: We have to use the password created earlier while formatting the disk.
    cryptsetup luksOpen /dev/sda data
Enter passphrase for /dev/sdb:
