Tutorial host multiple website using Virtualmin

Now, i want to share my experienced in hosting multiple websites on your VPS that running Centos 6 64 Bit, using Virtualmin as web management. In previous tutorial, i have share how to install wordpress in VPS, and if you follow my tutorial from beginning (all tutorial are in this blog, just visit angelimus.blogspot.com) i have install many packages to my VPS and NOT Using Fresh Install to Install Virtualmin, so there are a few thing can cause trouble in future, but it's not a big deal, i believe that every problem has a way out.

Since installing Virtualmin, i use VPS from Evoburst.com, cause it have more than enough RAM and CPU Resource.

Now, after through the "boring part" (Tutorial Post-Installation Wizard Virtualmin) but maybe the important ones.

If in your VPS you install SSH Dropbear (Part 5 - Installing SSH Dropbear on Centos 6 64Bit), then you must follow this tutorial from Step 1, if you not installing SSH Dropbear, just skip this step, and go to Step 2

Step 1 : Solving conflict on Port 443 between SSH and SSL

Open your terminal

sed -i 's/OPTIONS="-p 443"/OPTIONS="-p 444"/g' /etc/init.d/dropbear

Now your port for SSH Dropbear is "444", conflict solved.

Step 2 : Register free domain at freenom.com
(If you already have registed domain you want to use, like mynewvps.com or mywebhost.com, etc, the point is it registered and still active, then you can skip this Step, go to Step 3)

1. Open your browser, and go to http://www.frenom.com (why freenom? because it free, no cost at all, and this is for testing purpose).
2. Find domain you like, then click check availability, choose from the list thats free, (see pic below)
   
3. Click Checkout
4. Click USE DNS, in type your VPS ip address there, type the same ip addpress on both. (see picture below)
   
5. Click continue, and follow the instruction until finish.

Step 3 : Host Multiple Website
Open your browser, and go to Virtualmin by type

https://<vps ip address>:10000/

1. Login with username = root and password = (your root password)
2. i assume you already done step (Tutorial Post-Installation Wizard Virtualmin)
3. See on left panel, Click on Create Virtual Server (see image below)

4. After click it, see on right panel

Domain name (from freenom.com) = angelimusvps.tk

Description = (type anything you like, eq web1, etc)

Administration password = (type anything you like, eq passweb1, etc)

Administration username = Choose Custom Username and write (from freenom) angelimusvps.tk

Custom username is directory name where your public_html or your directory for website files.

eg: if you type angelimusvps on Custom username, and then in number 7 below, it must be

cd /home/angelimusvps/public_html/

I highly recomended that you using Custom Username same as your Domain name for beginning, so it will not confuse you in the future.

5. Open your browser, try input your domain from freenom (my domain is angelimusvps.tk)

6. It show Forbidden, because there are no website file

7. Now Open your terminal, type

cd /home/angelimusvps.tk/public_html/
echo "This is My First Website using Virtualmin - angelimus.blogpsot.com" >> index.html

Note : change angelimusvps.tk with your created domain

8. Try open your browser again, and type your domain

9. Now you're done,
10. To Create Multiple website, just go to Step 1

when you get stuck into trouble, just take a rest a while... because in the same time, you already resolve it without knowing it

Tutorial Post-Installation Wizard Virtualmin

Now we will configure Post-Installation of Virtualmin, there was a simple wizard provided by Virtualmin to setting Virtualmin based on your VPS resource.

Let's start Post-Installation Wizard
I assume, you already done installing Virtualmin (Install Virtualmin on Centos 6 64 Bit)
Open your browser.

https://<vps ip address>:10000/

you will see like this (see pic below)

Click Next

Memory Use

1. Preload Virtualmin libraries?
- if your VPS have low resource of memory and you have low frequency of visiting Virtualmin, Disable this option, but if you have more RAM, Enable this.
- Even you Disable this option, Virtualmin UI run stable.

2. Run email domain lookup server?
- if you have high activity in emailing, enable this.
- but if you have less memory, disable this, your email processing is bit slower.

Virus Scanning
Run ClamAV server scanner?
- if your server have high intense of receiving email, you better enable this option, because it lower your CPU Usage but consuming more memory (100Mb), so if you think your server will have activity in emailing, its better to rent vps with high ram
- if your server have low frequency of emailing, disable this.

Spam filteringRun SpamAssassin server filter?

- If your system is going to host domains that will receive a large amount of email, filtering incoming messages for spam can generate significant CPU load. This is due to CPU use by the SpamAssassin mail filter when it is started, so its better you enable this, because its only consume 30Mb,

Database Servers
1. Run MySQL database server

2. Run PostgreSQL database server

- If your server only run email server or DNS hosting, you not need both option above, but if you want to host website on your VPS, i recomend enable MySQL database server, its has more compatible with application nowadays.

Note : if you see >> MySQL has been enabled, but cannot be used by Virtualmin. Use the MySQL Database module to fix the problem.

It means you have not entering the mysql password, just click next, and you'll be asked for MySQL username and password. (check previous tutorial about mysql).

After that the wizard will ask if you want to change the password.

MySQL database sizeMySQL can be configured to trade off memory use for performance, depending on how much RAM your system has and how heavily you expect the database to be used.

The option is clearly explained about how often your mysql is used. If you not sure, just choose leave defaul settings

DNZ Zone

For this, just type server1.angelimus.com or serv1.example.com, etc, ant tick "Skip check for resolvability". I'll explain this in later tutorial.

Password

For this, read the explanation carefully, for me, i choose Store Plain text Password, but i strongly recomended you using Only Stored Hashed Password i'll create this tutorial later.

All Done. Click Next

Install Virtualmin on Centos 6 64 Bit

Hello, today i want to share how to install Virtualmin as Web Management for VPS. Virtualmin is a powerful and flexible web hosting control panel for Linux and UNIX systems based on the well-known Open Source web-based systems management GUI, Webmin. Manage your virtual domains, mailboxes, databases, applications, and the entire server, from one comprehensive and friendly interface.

Note : Because there are a lot of tutorial regarding Virtualmin, so in this tutorial i just share how to install virtual min and what requirement to run Virtualmin, another tutorial will be on diffrent page of tutorial, i will post it one by one, just wait for it, all tutorial about Virtualmin will be updated in this page.

Link my Tutorial about Virtualmin on Centos 6 :

How To Create Sub-Server Virtualmin

How To Create Sub-Domain in Virtualmin

Read this FAQ carefully (Link Source FAQ):

1. Should I install Webmin before I run install.sh?

- No. The install script runs best on a freshly installed Grade A supported Operating System.

2. Should I install Apache, Postfix, MySQL, Dovecot, etc. before I run install.sh?

- No. The install script runs best on a freshly installed Grade A supported Operating System.

3. What if I already installed Webmin on my system?

- If you installed from the standard package type for your system downloaded from Webmin.com or Virtualmin.com, everything should be fine. Running install.sh should work without any trouble.

- If you installed from a third party source, or you don't know where it came from (like it was provided on a dedicated server you've rented from your hosting provider), you should uninstall it, and make sure whatever software repository it came from has been disabled.

4. What if I already installed Apache, Postfic, MySQL, Dovecot, etc. on my system?

- If you installed from the OS standard repository for your OS, everything should be fine. If you installed from any third party sources, or from source, the installation will fail and things will go badly. The install script cannot accommodate packages installed from non-standard sources. It just isn't that smart.

- If you can re-install your OS, it is recommended that you start with a freshly installed Grade A supported Operating System.

Explanation about the FAQ.

In point 1 and 2, it mention about install.sh, it means a script to do an automate install of Virtualmin that officially provided by Virtualmin.com (here is the link)

How about my experienced?

• I Have successfully install Virtualmin without re-install my OS, Before i install Virtualmin in my VPS, i have do several package instalation from my own tutorial in this blog including MySQL, SSH Dropbear, PPTP VPN, Wordpress, and KDE.
• I'M NOT SAID that my installation of Virtualmin, there are no problem in future because i'm not re-install the OS.
• Point 4 in FAQ, encourage me to NOT re-install the OS, because all my packages are from standard repository of Centos 6, you maybe seen my previous tutorial not like the ordinary tutorial, many source i used from github, actually what i grab from github (my own account zaq111 for storing code) is my own code that i create to automate the installation, so people can simple remember.

Okay, lets Start, hope there are not much trouble in Future

Open your terminal and type this (or just copy and paste it on your terminal)

wget http://software.virtualmin.com/gpl/scripts/install.sh
sh ./install.sh

Just wait and follow the instruction, this process may takes about 10 - 20 Minutes or maybe less (i not sure about this, because when i install, i go for about 1 hour to the market :P) After installation complete.

Open your browser, and add your VPS IP or domain in browser.

https://<vps ip address>:10000/

Username = root

Password = your root password

Until this step, i will stop the tutorial, it means you have install successfully Virtualmin, but its not over yet, there are a few configuration to make Virtualmin running smoothly on your VPS and not overload the CPU or Memory. See you in next tutorial about Virtualmin.

Tutorial Install KDE on Centos 6 64Bit

Hello, now i'm gonna share how to install KDE on Centos 6, a lot of tutorial like this before, many of them are good, no much trick available in this tutorial, so its generally same.
Why KDE, i prefer KDE, because i use less memory than GNOME, maybe i wrong, but this is what i feel, maybe for some other, they prefer GNOME, its like taste, diffrent people with diffrent taste :P
For now, i will not include explanation from wikipedia, maybe you can search by yourself :P

FYI : In this tutorial i using my VPS from Evoburst.com, (Low Price VPS) because it have 4GB of Memory, and SSD Support, but if you using another VPS Host, there are no problem at all.

Okay, lets start installing KDE.

Part 1 - Installing KDE on Centos 6

wget https://raw.githubusercontent.com/zaq111/bash/master/angelimus-install-kde.sh

chmod +x angelimus-install-kde.sh && ./angelimus-install-kde.sh

this maybe take a while, about 3-10 minute, depend on your VPS internet speed and your VPS processor performance, and you will see this (see pic below)

Input Password and Verify

Now you have done install KDE on your Centos 6, and then, the next step is accessing your KDE from Windows using Real VNC.

Part 2 - Accessing KDE from Windows using RealVNC

Now download VNC Viewer from www.realvnc.com or https://www.realvnc.com/download/viewer/

Install it, and open it.

Tutorial Install PPTP VPN on Centos 6 64Bit

Hello, today i want to share how to install PPTP VPN on Centos 6 64Bit. First we must know what is PPTP and how it works, below is a little information about PPTP that i found on wikipedia.com

The Point-to-Point Tunneling Protocol (PPTP) is a method for implementing virtual private networks. PPTP uses a control channel over TCP and a GRE tunnel operating to encapsulate PPP packets.

A PPTP tunnel is instantiated by communication to the peer on TCP port 1723. This TCP connection is then used to initiate and manage a second GRE tunnel to the same peer.

The PPTP GRE packet format is non standard, including an additional acknowledgement field replacing the typical routing field in the GRE header. However, as in a normal GRE connection, those modified GRE packets are directly encapsulated into IP packets, and seen as IP protocol number 47.

The GRE tunnel is used to carry encapsulated PPP packets, allowing the tunnelling of any protocols that can be carried within PPP, including IP, NetBEUI and IPX.

In the Microsoft implementation, the tunneled PPP traffic can be authenticated with PAP, CHAP, MS-CHAP v1/v2 .

Terms of Using VPN From Ryan B @Evoburst.com

Next will checking requirement of installing PPTP VPN

Part 1 - Check Requirement PPTP VPN and Installing PPTP VPN

1. Check if TUN/TAP is enabled (you can enabled it in Control Panel)

For this tutorial, i'm using VPS Host from EvoBurst.com (Low price VPS)

Here is some feature that provided by EvoBurst.com

Note : in some VPS Host, there are no Feature of Enabled TUN/TAP and PPP, but dont worry, you can try send ticket to your host, to request for enabling TUN/TAP and PPP for VPN Purpose, there will process your ticket and enabled it, i have experienced that matter in interserver.net. In some VPS Server, maybe it take about at least 1 Hours till your ticket processed but sometimes it takes only 5 minutes or less, depend how busy your customer service of your VPS Host.
Ok, after TUN/TAP and PPP enabled, open PuTTY and check by type

cat /dev/net/tun

if the result is cat: /dev/net/tun: File descriptor in bad state, it means TUN/TAP is enabled (see pic below)

TUN/TAP is enabled

 type

cat /dev/ppp

if the result is cat: /dev/ppp: No such device or address,  it means PPP is enabled (see pic below)

PPP is enabled

Now, you are ready installing PPTP VPN, just code below, and it will do all what your server need.

wget https://raw.githubusercontent.com/zaq111/bash/master/angelimus-install-pptpd-VPN.sh 

chmod +x angelimus-install-pptpd-VPN.sh && ./angelimus-install-pptpd-VPN.sh

While installing, you will be prompt 2 times, just answer with "y"

1st prompt answer with "y"

2nd prompt answer with "y"

After done installing you will see 

This is your IP to connect

Your Username and Password to connect to VPN

Until this step, you're done Installing PPTP VPN on your Centos 6, Now, time to check if your VPN Works, i test my VPN using Windows OS,

1. Go to Control Panel > Network and Sharing Center

2. Click on Set up a new connection or network

3. Click on Connect to a workplace

4. Click on Use my Internet Connection (VPN)

5. See dialog box

Internet address = (your given ip when finish installing your VPN or usually your VPS IP)

Destination Name = Choose whatever you like eg : My Personal VPN

6. Click Next

Username = angelimusVPN01

Password = pass001

7. Click Next and Wait until you see you are connected.

8. Done, try open browser and goto myipaddress.com

NOTE : (Ignore this when you can browse the internet using VPN)

Why i can't connect to Internet using VPN,

In some VPS Host, using this tutorial will works fine, BUT now i using my VPS from Evoburst.com, and why i use evoburst? because i know the VPN will Connect Smoothly, BUT WITH NO INTERNET ACCESS don't worry, i'll show how to.

1. Open PuTTY and Check your network interface

ifconfig eth0

it will return 

eth0: error fetching interface information: Device not found

this is the problem since in my auto install script, i use :

iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

that is means to add rule for eth0, because common VPS Host use eth0,

if we see from ifconfig eth0 there is no device found, so what is my device? type

ifconfig -s

in my VPS Host (Evoburst.com) you will see like this (see pic below) the result may vary on other VPS Host

see, there are only : (see pic above)

lo (loopback)

ppp (point to point protocol)

venet0 (virtual ethernet network, i'm guessing it :P) which is act as phisycal adapter

now, we found the device, which is venet0

so, dont take it to long, just type 

iptables -t nat -A POSTROUTING -o venet0 -j MASQUERADE
service iptables save
service iptables restart

Now try to connect again your VPN, i hope it works. (if you experience another error, post it on comment section, maybe i can help to find out.)

Part 2 - Add or Remove VPN user

This part is very simple, just add this code (edit chap-secret)

vi /etc/ppp/chap-secrets

to edit this file, press insert

to Remove User angelimusVPN01, just delete that line until *

to Add User, type

<VPN Username> <pptpd> <VPN Password> <*>

eg: VPN001 pptpd Pass001 *

It means, VPN001 is the username, pptpd is the type of VPN, Pass001 is the password, * is wildcard for all ip address.

saving the file press ESC on keyboard, then type :wq

All Done, hope you can install VPN on your VPS without trouble, if you have reference about VPS, you can post it on comment section.

With the very strict TOS, i can tell you, this server is for legal activity only, or in other word "Don't mess with this VPS Host"
Why? First, the price is very low, comparing to another competitor, Second, it's limited, Third i bet you cant find this offer again. Now, lets review some of EvoBurst VPS Plan (see below)

Evoburst4G

CPU : Fair Share 24+ Cores

Memory : 4GB RAM

HDD : 30GB SSD/SAS Disk Space

Bandwidth : 3TB Bandwidth

IP Address : 2 Dedicated IPv4

IPv6 : /64 IPv6 Subnet

Max VPS : 2 VPS Limit

Location : Seattle, Washington - Dronten, The Netherlands - Los Angeles, California

Price : €6.00

See Another VPS Plan : https://www.evobilling.com/cart.php

I already bought EvoBurst4G, first i test the connection speed (see pic below)

this is from location : Los Angeles, California

https://www.speedtest.net/result/4416318261.png

Now, lets go to Client Area

Let's go more detail

I use all resource into 1 VPS (EvoBurst4G Plan), but you can split it with equal resouce and create max 2 VPS, and you can create 4 VPS with EvoBurst6G (€10.00 EUR Monthly) and 8 VPS with EvoBurst8G (€20.00 EUR Monthly).

Note, you can create multiple VPS, as long you have enough resource, eg : You buy EvoBurst4G with 4GB Memory, in EvoBurst4G you can create 2 VPS, 1st VPS using 3GB memory, so your memory for 2nd VPS is just 1GB, it apply to Disk Space, Bandwidth, and IP Address.

There are Feature to Enable or Disable TUN/TAP

What is TUN/TAP

TUN (namely network TUNnel) simulates a network layer device and it operates with layer 3 packets like IP packets. TAP (namely network tap) simulates a link layer device and it operates with layer 2 packets like Ethernet frames. TUN is used with routing, while TAP is used for creating a network bridge.

Packets sent by an operating system via a TUN/TAP device are delivered to a user-space program which attaches itself to the device. A user-space program may also pass packets into a TUN/TAP device. In this case the TUN/TAP device delivers (or "injects") these packets to the operating-system network stack thus emulating their reception from an external source.

So far, what i know from tun / tap is its related into VPN PPTP (dont worry, will try installing later, just wait), Next,

Graphs about resource usage

Second, Control Panel.

Eq : you setup 2 VPS using Evoburst4G, and then you can manage it in here (see pic above)

all your VPS will listed there

Click on Manage

In this panel, you can Reboot, Shutdown, Boot, Reinstall OS, Enable TUN/TAP, Enable PPP, Configure Network, ETC.

Third, what can this VPS do???

In this part, i will test installing and using tutorial from part 2 to part 5 and do another tutorial with this VPS.

Part 2 - Access your VPS using PuTTY ✔ (see pic below)
