Installing on Amazon Linux 2

Prerequisites

Recommended EC2 instance type is i3.xlarge.

  1. Install OpenJDK 11 by running the following command:
    amazon-linux-extras install -y java-openjdk11

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

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

  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 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

Verify Installation

Once you see the message "The service has started", wait for few seconds then go to http://localhost:8080/searchblox/admin/main.jsp to validate.

  • You can verify if SearchBlox has started successfully by viewing the status.log file in the <SEARCHBLOX_INSTALLATION_PATH>/webapps/searchblox/logs folder.

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 following steps:

  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:
yum remove searchblox
