If you are looking for a clean and modern web hosting panel but you don't simply have the funds to pay for one, Sentora is your answer. Sentora is an open source web hosting panel that is designed to simplify your web hosting experience.


  • A Vultr VPS (768MB should work fine).
  • One of the following supported OS: CentOS 6 & 7, Ubuntu 12.04 & 14.04
  • Registered domain name.
  • Public IP for your server.
  • 5-10 minutes of your time.

None of the following installed:

  • MySQL
  • Apache
  • PHP
  • Bind
  • phpMyAdmin
  • RoundCube
  • Dovecot
  • Postfix
  • proFTPd

The following ports opened:

  • 20 & 21 : FTP
  • 25 (TCP) : SMTP
  • 53 (TCP & UDP) : DNS
  • 80 (TCP & UDP) : HTTP
  • 110 : POP3
  • 143 : IMAP
  • Optional: 443 (HTTPS) and 3306 (MySQL)

Note: Your server OS should be freshly installed. Nothing else should be installed or it may mess with the installation process. This includes other management panels, web services, databases, mail servers, etc. If you have any of these installed, either uninstall them or reload the operating system to a fresh state.

Installation Process:

Once you are ready to start, you will want to log into your DNS management panel where you manage your domain name and the host records. Create a sub-domain that points to your server's IP address. The sub-domain will be used to access your panel later on. It could be or, whatever you prefer.

Step 1:

Once you have this done, log into the server you would like to install the panel on. We'll be installing the latest stable version of the panel today. Start by typing the following command:

 bash <(curl -L -Ss

This will download and start the installation process for you. A script will run and you'll need to answer the questions asked. It'll look something like this:

Step 3:

Now you will be asked what timezone you are in. Similar to the previous steps, type in the number of your time zone. Multiple options are given in each timezone, so be careful to choose the correct one. Google can be your friend in this case.

After choosing your timezone, the system will ask to confirm the information you provided. Enter 1 if the information is correct, enter 2 if you need to change something. Once confirmed, we can move on to the next step.

Step 4:

Enter the sub-domain you assigned earlier. By default, the system will input the server's hostname. Erase this and type in the sub-domain address you assigned earlier, unless the hostname is the same as your sub-domain.

 Enter the sub-domain you want to access Sentora panel: <//Sub-domain here//>

Step 5:

Confirm the public IP for the server. It should already have your IP address listed. Hit enter if it is correct. Otherwise, erase it and type in the correct IP address and hit enter.

 Enter (or confirm) the public IP for this server:

Note: if you have not assigned a sub-domain to your IP address, you will see a warning message after hitting enter. You can safely ignore this if you plan on assigning a sub-domain later. Simply enter y to continue or n to change the domain/IP or q to quit the entire installation process.

Step 6:

You are pretty much done now! From this point on, you will see your system installing necessary packages in order for your panel to operate successfully. Let this run for a few minutes.

It will also install MySQL for you, so you will want to keep note of the usernames and passwords it assigns you. Never fear, the script will generate a file that has the passwords for you. It should be stored in /root/passwords.txt.

Also note that at the end of the installation process (in the Congratulations summary), it will tell you your Sentora username and password. Keep note of this!

Step 7:

Once you have kept note of the important information, it will ask to reboot your server to complete the installation. Enter y to allow the reboot process.

Congratulations! You have successfully installed Sentora as your new web management panel. You may access it by entering the sub-domain address (or IP address) into your browser and log in.
