🚧

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/console https://exampledomain:port/search/index.html

# Change SearchBlox Server Port

**SearchBlox Server runs on port 8443 by default.**

• For secure ports refer **Secure Ports used by SearchBlox** section on [Requirements](🔗).

You can change the port by following the steps below:

1. Stop SearchBlox service

2. Edit the file /opt/searchblox/start.d/https.ini and add the below line to set the required port number: jetty.ssl.port=443

3. Save the file https.ini

4. Start SearchBlox service

🚧

Port Update

Fix the permission denied error while using searchblox service on less than ports 1024, run the below commands: Check the Java Path

# `readlink -f $(which java)`

Set the capability to bind low ports for non-root searchblox user.

# `setcap cap_net_bind_service+ep <javapath>`

# Uninstall

1. First Stop the SearchBlox, by running the command: `systemctl stop searchblox`

2. Run the following command to uninstall or remove SearchBlox: `apt-get remove searchblox`

3. To remove the user, run the command; `userdel 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`

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`
