# 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` `sudo chmod -R 755 /opt/searchblox/elasticsearch/logs` `sudo chmod -R 755 /opt/searchblox/connectors`

7. Start SearchBlox service by running the following command: `systemctl start searchblox`

👍

Note:

SearchBlox service will start elasticsearch and analytics services internally unlike previous versions. If service start up gives any issues, enable searchblox.service using the command below: `systemctl daemon-reload`

8. Stop Analytics, SearchBlox and Elasticsearch services by running the following command: `systemctl stop searchblox`

9. To verify the status of the SearchBlox service please use the following command: `systemctl status searchblox`

# Verify Installation

After you start the services, wait for 30 seconds then go to https://<Hostname or Host IP>:8443/console/ to access the SearchBlox Management Console to login.

You can also verify if SearchBlox has started successfully by viewing the **status.log** file in the `/opt/searchblox/webapps/ROOT/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.
