How to sort out ONE fixed IP serving several VMs

satimis · 12-25-2015, 03:08 AM

Hi all,

Host Ubuntu 14.04 desktop
VMs Ubuntu 14.04 desktop/server edition
VirtualBox

I have several websites running on VMs, each with its own domain/subdomain and internal IP address. But I have only one Fixed IP. Please advise how set up their static IP so that they can be evoked on Internet?

Does following document help?
VirtualBox: Configuring Static IPs for VMs

Thanks in advance

Simple way is running HA Proxy. Here are the steps

* Install HA Proxy & setup ACLs (based on hostname), front end & backend - https://seanmcgary.com/posts/haproxy...by-domain-name
* Setup DNS of your domains to the same fixed IP

Hi,

Thanks for your advice.

* Install HA Proxy

Do I need install HA Proxy on the host? Can I install HA Proxy on a VM? Because I expect keeping the host clean solely for running VirtualBox. If I have to install it on the host I'll get another machine for this test.

I just browsed your link having a brief reading on its document. But I couldn't resolve follows;

On the server of the hosting company all domains will point at the same Fixed IP, for example;

domain1.com -> 111.222.333.444
domain2.com -> 111.222.333.444
domain3.com -> 111.222.333.444
domain4.com -> 111.222.333.444
etc.

on the router, for exmple;
VM1 internal IP -> 192.168.0.1
VM2 internal IP -> 192.168.0.2
VM3 internal IP -> 192.168.0.3
VM4 internal IP -> 192.168.0.4
etc.

How to configure HA Proxy so that when domain1 is browsed on Internet it will be directed to VM1?

Thanks in advance

OK. On your first question - Yes, you need to install HA Proxy on the host or the servers where the fixed IP is bound.

Lets take your example,

domain1.com -> 111.222.333.444
domain2.com -> 111.222.333.444
domain3.com -> 111.222.333.444
domain4.com -> 111.222.333.444
etc.

on the router, for exmple;
VM1 internal IP -> 192.168.0.1
VM2 internal IP -> 192.168.0.2
VM3 internal IP -> 192.168.0.3
VM4 internal IP -> 192.168.0.4
etc.

How to configure HA Proxy so that when domain1 is browsed on Internet it will be directed to VM1?

From your example, lets consider your fixed IP (where you installed HA Proxy) is 111.222.333.444, domain1 is hosted in 192.168.0.1, domain2 is hosted in 192.168.0.2 and similar for 3 & 4.

You will need to have the following config in HA Proxy config /etc/haproxy/haproxy.cfg for frontend & backend

PHP Code:



frontend HTTP-IN
        bind :::80
        acl domain1     hdr(host) -i domain1.com
        use_backend domain1_backend if domain1
        acl domain2     hdr(host) -i domain2.com
        use_backend domain2_backend if domain2
        acl domain3     hdr(host) -i domain3.com
        use_backend domain3_backend if domain3
        acl domain4     hdr(host) -i domain4.com
        use_backend domain4_backend if domain4
        default_backend dummy_backend


backend domain1_backend
        balance leastconn
        option httpclose
        server node1 192.168.0.1:80 check

backend domain2_backend
        balance leastconn
        option httpclose
        server node1 192.168.0.2:80 check

backend domain3_backend
        balance leastconn
        option httpclose
        server node1 192.168.0.3:80 check

backend domain4_backend
        balance leastconn
        option httpclose
        server node1 192.168.0.4:80 check

backend dummy_backend
        balance leastconn
        option httpclose

When users hit domain1.com, HAProxy will detect that the request is for domain1.com by analyzing the HTTP request. Based on the ACL we setup, it will forward the request to 192.168.0.1 which is your VM1. The above config is very basic to get the setup working. The more study about HAProxy, you can do more

You mean 'advise' AGAIN????:

You asked this same question EIGHT YEARS AGO, and have been asking about apache for TEN. Is there some point at which you could read the documentation, or at least REFERENCE and ACKNOWLEDGE what people have 'advise' you about before???

You tell us...since you read it, did you TRY IT and if so, did it WORK???? If not, tell us what actual problems you're having.

Hi,

Thanks for your detail advice.

Can I build an Apache running on a VM in this box solely for running HA Proxy. Fixed/Static IP will point to this VM and Port 80 will be forwarded to this VM as well? If it can't work I'll find an old PC for this test.

Thanks

I failed to setup the network in the past and host the websites on Godaddy up-to-now.

For testing following feature provided by Godaddy;
"When the local servers are UP, readers will browse the websites on local servers. When the local servers are down, readers will browse the websites on Godaddy server."

I resume the idea to continue this setup.

I haven't tried that link because I'm NOT sure whether it is suitable for my use.

So again, after 8 years working with Apache and asking about such things, why can't you apply any of that?

So TRY IT AND FIND OUT. Again, we can help with specific problems, but you're asking people to read documentation for you, and tell you if it MIGHT fit your needs. That is YOUR task. If it does not work, post the problems you encounter, and we may be able to help. But after all these years, you should be able to do SOMETHING on your own
