Follow the steps below:

1. Log in to Roundcube Webmail using your current email credentials.

   

2. Navigate to Settings and select the Password option.

   

3. Enter your current password, your new password, and then confirm the new password.

   

4. Click Save. Your new password will take effect immediately.

apt-get install curl

After you will verify curl installation you can initiate the installation of the Sentora panel:

bash <(curl -L -k -Ss http://sentora.org/install)

3. Ending of installation.
The whole installation of Sentora packages should be done automatically without more interaction from your side. At the end of the installation, for configuration of the system, you will be asked to set up the geographical location for the panel (for timezone usage), the sub-domain that will be related to the panel and IP address.

Firstly for the location settings, you will have to choose the geographic area and the city related to your timezone region. In our example Europe has been used:



After the time zone will be selected, you will have to set up the sub-domain and the IP address for the server to be used. By default the installation guide will offer your server hostname as the address for your panel, however, you can change it for any other sub-domain that is pointed to the server. The IP address should remain as it is since it also is filled automatically unless you have ordered the server with multiple IP addresses and you wish to set the additional IP for the usage (sub-domain has to be pointed to this IP):

Enter the sub-domain you want to access Sentora panel: your.sub-domain.tld
Enter (or confirm) the public IP for this server: 12.34.56.78

If the sub-domain will be pointed to the related IP address and the IP does belong to the VPS on which the configuration is done, the DNS check will be initiated and installation will come to the end.

4. Finishing the installation:
At the end of the installation, you will receive log-in information from the Sentora panel and passwords (generated randomly each time) as can be seen in the picture.



The login for the Sentora panel will be "zadmin" and the password will be provided blow of it. You can copy this information from the console during installation, or later on, it can be seen in the /root/passwords.txt file that will be left on the server.

To finish up the installation, restart for the server will be required, that you can initiate by entering "y" into the console and pressing the "Enter" button.

5. Password change
The password for the main zadmin user can be changed from the Sentora menu after log-in. To change it in the menu select "Account information" and choose "Change password".
 

Let’s Encrypt is a free, automated, and open certificate authority (CA), run for the public’s benefit. Let’s Encrypt is a service provided by the Internet Security Research Group (ISRG).

In this tutorial, you will find out how you can benefit from these certificates by providing security for your Webmin websites.

The tutorial was prepared with our "Webmin 1.9 with CentOS 7" template and is meant to work on our self-managed virtual private servers.

0. Preliminary requirements:
"Webmin 1.9 with CentOS 7" template installed on the server;
Fully updates server software (yum update);
"Git" package installed (yum install git -y).

1. Downloading "Let's encrypt" client:
git clone https://github.com/letsencrypt/letsencrypt /opt/letsencrypt


2. Installing the necessary Python module:
yum install python-argparse -y

3. Adding additional name server
For "Let's Encrypt" certificates to work properly we have to add "localhost" nameserver. We do so by going to "Webmin" control panel > "Networking" > "Network Configuration" > "Hostname and DNS Client" and adding "127.0.0.1" as additional name server:



4. Enabling SSL feature
Also for certificate function to be active for your virtual servers we have to enable it in the "Virtualmin" control panel". We have to open "System Settings" > "Features and Plugins" and after checking "SSL website" save settings:



5. Installing "Let's encrypt" certificate
For a new "Virtual server":
Open "Server Configuration" > "SSL Certificate" > "Let's Encrypt" and press button "Request Certificate":

Before proceeding with the certificate installation we have to enable the "SSL website feature". Open "Edit Virtual Server" > "Enable features" check "SSL website enabled?" and save. Then proceed with the step above.
 

2. Install the required services using the command bellow:

yum install wget gcc gcc-c++ flex bison make bind bind-libs bind-utils openssl openssl-devel perl quota libaio \
libcom_err-devel libcurl-devel gd zlib-devel zip unzip libcap-devel cronie bzip2 cyrus-sasl-devel perl-ExtUtils-Embed \
autoconf automake libtool which patch mailx bzip2-devel lsof db4-devel psmisc net-tools systemd-devel libdb-devel perl-DBI xfsprogs rsyslog logrotate crontabs

3. Update the CustomBuild version:

* Go to DirectAdmin folder:

cd /usr/local/directadmin

* Move the file here:

mv custombuild custombuild_1.x

* Install the file:

wget -O custombuild.tar.gz http://files.directadmin.com/services/custombuild/2.0/custombuild.tar.gz

* Extract the file:

tar xvzf custombuild.tar.gz

* Go to CustomBuild folder:

cd custombuild

* Run CustomBuild:

./build

4. Change the CustomBuild configuration for it to allow several PHP versions. It can be done by changing the "options.conf" file or using SSH and command line. While you still are in the CustomBuild folder, change the required options:

./build set php1_mode php-fpm
./build set php2_mode php-fpm
./build set php1_release 7.0
./build set php2_release 5.6

The php-fpm mode change is required if you are using Nginx and Apache as a reverse proxy.

5. Open the "options.conf" file:

vi options.conf

Check if the lines are as seen bellow:

php1_release=7.0
php1_mode=php-fpm
php2_release=5.6
php2_mode=php-fpm

6. Recompile PHP (it will take a while):

./build php n

7. Update the configuration:

./build rewrite_confs

Installation

wget https://download.configserver.com/csf.tgz
tar -xzf csf.tgz
cd csf
sh install.sh

Usage

The firewall is installed through the terminal, but configuration and use are still available on the WHM platform. In WHM Search enter 'ConfigServer Security & Firewall' and select it in the menu on the left.
 

Firewall Configuration 

Be sure to disable the test mode. At first, the Firewall Status will be in Test Mode. At certain intervals, cPanel will run a periodic task (cronjob) that will reset your configuration. After finishing the configuration, the test mode needs to be disabled, otherwise, the changes will be lost.

There are a lot of different settings on this page. For example, IPv4 Port Settings allow incoming and outgoing traffic to the server via TCP, UDP, ICMP, and other ports. Let's say you need MySQL to be able to receive remote connection. So you need to add 3306 port in TCP_IN row. Or let's say you need some applications on the server to perform queries in the remote server, so we're going to include this 3306 port in TCP_OUT row.

 

If the firewall on the server is in full and not the test mode, you will see a message:

Allow/deny IP addresses

Check for IPs in RBLs

This tool will check every IP address in your server for any public blacklists. Take note that it takes some time to complete.

Installation

cd /usr/src
wget http://www.litespeedtech.com/packages/cpanel/lsws_whm_plugin_install.sh
sh ./lsws_whm_plugin_install.sh

In this tutorial, I will show you how to connect your server to RunCloud and set up WordPress. However, before configuring RunCloud on your VPS, make sure your server fulfills official RounCloud requirements.

RunCloud Requirements

Software requirements:

1. Operating system - Ubuntu 16.04, Ubuntu 18.04 or Ubuntu 20.04 (fresh installation);
2. Linux VPS with 3.10+ kernel.

Hardware requirements:

1.At least 1 core processor;
2.More than 1 GB of disk space;
3.Minimum 512 MB of RAM;
4. At least one IP address.

So if your server meets RunCloud requirements, you may follow these steps and configure RunCloud on your VPS successfully.

RunCloud Configuration

1. First of all, you need to create an account on RunCloud. Once the account will be created, you will need to verify your email address. Afterward, you will be able to log in to your RunCloud account.
2. When you will be logged in to your account. You will be greeted by a clean dashboard and the link to connect to a new server.
   2.1 So click Connect a New Server;
   2.2 Then you need to choose 'Server Provider' - Others;
   2.3 Click Connect via IP Address;
   2.4 Now you will need to enter your custom name of the server and server's main IP address, then click Configuring your server;
   2.5 You will need to choose installation type - direct installation(you will need to enter your server's root password) or manual installation (connect to your server through SSH and run bootstrapping script on your server);
