# Change SearchBlox Server Port
**SearchBlox Server runs on port 8080 by default.**
You can change the port by following the steps as shown in the following:
Stop SearchBlox service
Edit the file _/opt/searchblox/start.ini_ at line number 163 as follows: `
jetty.http.port=8080`Start SearchBlox service
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
Uninstall or remove SearchBlox by running the following command:
`yum remove searchblox`
# Disk Encryption
Additional Disk is required for disk encryption
Installation of cryptsetup for RHEL / CentOS `
yum install cryptsetup-luks`LUKS Format disk Note: while formatting the disk we have to give some password `
cryptsetup luksFormat /dev/sdb`
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`
Mounting the new file system at `
/opt` `mount /dev/mapper/data /opt`To get UUID `
blkid /dev/mapper/data`
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`
# CentOS Full Disk Encryption
Important Note
Before installation of OS, the entire root volume can be encrypted using the following steps for GUI based CentOS systems
To enable the disk encryption please go to installation destination
While installing Centos7 Installation **Enable the Encryption**.
Next create Disk Encryption Passphrase.
On reboot you would get the following prompt to enter the passphrase so that you can successfully unlock the drive:
Please use the command as in the following screenshot to verify the disk Encryption
