Feb 26, 2015I have a task of converting a current Win Server based apache server from multiple IP based virtual hosts to a full name based virtual hosting.I'm famiilar with the steps but I was wondering if there are any gotchas in Windows that I should be aware of. It seems that now matter what I change in the new config it doesn't work or work as expected.

View 0 Replies View RelatedHTTPS Not Working - Cpanel Based Site
Mar 28, 2007Today, I've purchased a RapidSSL Certificate for my site with Cpanel and https:// access did not work.
What I did was :-
1) Generate a Private Key
2) Create a CSR Request Certificate
3) Submit that and installed the Certificate in WHM for the site.
The site is running on a dedicated IP and it works as http:// but not with the https:// .
I checked and Cpanel did include the SSL directive for the site in httpd.conf and have rebooted the server and restarted httpd but to no avail.
I also had OpenSSL 0.9.8.3a installed and update WHM. The Apache 1.x was installed with OpenSSL Support too.
Is there a SSL Server or something which may not be active ?
How To Disable All Email Services On Cpanel Based System
May 22, 2008For one of my server based on cpanel i want to disable all email services/ send/receive etc. How do i go about it ?
Would Main >> Service Configuration >> Service Manager be the best place and disable the following services :
antirelayd
POP before SMTP daemon
exim
SMTP Server
imap
IMAP Server
pop
POP3 Server
spamd
SpamAssasin Server (if you choose to disable this, you should disable SpamAssasin in tweak settings as well)
Would that be enough to stop any emails from going out of server? Say via any contact form or any other way?
Please advice or i need to do it mannually via ssh and disable them.
I have SIM installed, so would i need to configure or remove something out of it too?

OpenVZ Max Ram
Sep 17, 2008I am being told that when a VPS in openvz hits the maximum ram assigned to it that openvz disables that vps.
Isn't the ram limit a hard limit that simply restricts the available ram to that container to XX ram?
Is this normal?

Overselling In OpenVZ
Feb 17, 2009Just how it actually works? I have a pretty good knowledge about Xen and Linux KVM (somewhat about VMware as well). Prior to joining WHT, I rarely heard about Virtuozzo and OpenVZ.
I'm just interested in RAM usage actually. I also read on some threads that you can oversell storage and net bandwidth as well? That just seems a little weird to me.
I also used a fairly good amount of Solaris Zones as well.
Example, if I have a 8GB box and I leave some, say 512MB, reserved for CT0. 8192-512=7680 (I know the ACTUAL RAM amount will NOT be 8192), that leaves 7680MB use for CTs. So technically in OpenVZ if you dice out dedicated 512MB VEs... you end up with 15 right?
So you are able to sell more than 15 VPSs on a 8GB server box? If also set all burstable RAM to 1GB for all VEs.
In Xen, when you set dedicated RAM it is taken away from dom0, period. That's all there is to it, no oversell (Xen 3.3+ you can use ballooning to overcommit RAM, I know).
Within CT in VZ, user is able to check beancounters to see the guaranteed/burstable RAM. Technically you can't lie to the users.
I researched around... when oversell in VZ and the RAM gets maxed out... VZ will try to slow/stop/kill processes in order to keep the guests happy, to me that's just dangerous. Why needs to kill processes for RAM saturation?
Anyone can shed some lights for me? Or point me to an article(s). It can be technical, I should be able to grasp.
Hypervm And Openvz Vps
Apr 25, 2009I am trying to create some vps using openvz but after creating the vps with the Centos basic template 304mb i can't ping the ip and i can't view the centos welcome page in my browser (using ip and not domain, so i don't need to change there anything yet) and the most important is that i can't connect to the vps using ssh
I aks for many good users about my problem but i don' found a solution yet.
I ask my DC about ip's and they told me that the ip's are routed in my server.
I follow this instructions:
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 50G 2.8G 44G 6% /
/dev/sda3 198M 21M 168M 11% /boot
/dev/sda5 408G 2.4G 385G 1% /vz
tmpfs 1012M 0 1012M 0% /dev/shm
I follow this:
I disable selinux by editing /etc/sysconfig/selinux and changing the line to selinux=disabled
and then run:
I just login using ssh as root and run the folllowing commands.
Did i have to move to another directory to run them or ?
setenforce 0
wget[url]
Next i open /etc/grub.conf
vi /etc/grub.conf
and change default=1 to default=0
Then i add the ip's at the pool and create a plan and then create a vps without any errors but nothing.
I try with my DC resolvers or the 4.2.2.1 4.2.2.2 but nothing.
I alo add at the settings the gateway with no results at all.
After all i can't ping the ip that the vps got from the pool even ping it and not possible to connect to it using the ssh Sad
HyperVM+OpenVZ
Apr 17, 2009When you're creating VPS container, you can ssh with that IP and login with your username and password correct? But, what is the problem when I successfully created a VPS, and when trying ssh into it, I can't. Ok, here we go. I want to create a 2nd vps and will be using it as my DNS server. I enter a set of IPs into HyperVM's IPpool. First IP: x.x.x.178 Last IP: x.x.x.182 Resolv Entries (space Separated) : Gateway (IP): x.x.x.x.177 NetMask: 255.255.255.248
Then I created a vps resource plan. And then I created a VPS and it use the first IP from above. I want to connect to SSH and want to make it as my DNS server but seems the IP are not responding, it wasn't even live. So, what is the problem here? Where I did wrong? Just to let you know, I successfully created 1 VPS before that and it works without any hiccups. Got even whm/cpanel installed as well on it. The thing that I suspected is that my DC pulled the IPs off me and assigned them to other server. Waiting for their reply on this though.

How Can Secure /tmp /var/tmp In OpenVZ VPS ?
Mar 15, 2007recently I got a VPS from cheapvps.co.uk and so far so good. Im getting used to the VPS enviroment. I tried to follow several guides about how to secure with noexec and nosuid the /tmp and /var/tmp and it did not work.
in http : / / www . webhostingtalk .com/showthread.php?t=474681&highlight=tmp points it must be done from the hosting. Same is said in http : // kb . swsoft . com/article_130_648_en.html.
I asked the hosting to do it and they told me as I got an Unmanaged VPS they cant do it for me.
Do anyone know how can be done ? I dont want to use tmpfs as it uses main memory.
VPS - Mananged, Non/ Xen Or Openvz
Jul 26, 2008i am looking to get away from hostgators extremely overloaded servers and get a vps. I have been admining linux servers for a while although never as a web server, but think i can handle that aspect. I have done a huge amount of research but dont know which way to go. One of the things thats rough is the control panels, i like cpanel and have only used cpanel but many charge alot for it. I have been considering an xl-256 plan from vpsland.com. they are east coast (i am in NJ, west coast is out) and their xl plan is xen with swap. But its $15 for cpanel and that is too much, i was thinking of trying directadmin for $6. Is directadmin any good? I need spamassasin and that stuff of course. To me its crazy that openvz has no swap and the server will crash if you reach max ram like at vpslink.com. I really liked vpslink.com's phone support but the west coast thing is rough. I have been looking at http://www.ubiquityservers.com/vps/new-york.php these guys but its virtuozzo, but cpanel is cheap only $5 a month. bodhost.com seemed cheap at $8 for cpanel. then i found this which sounds great! especially since its close but i emailed them to ask if its xen or openvz and havent heard back in almost 12 hours which scares me for support. i like phone support but vpslink.com again was on the west coast. their cpanel was cheap though at $8. plus i dont know if i want managed ro not then i remembered this site, and remembered i had gotten alot of help hear before so i figured it be best to hear others experience and favorites, etc.

Sep 23, 2007I am aiming to offer VPS based on OpenVZ. Have some questions, please help to answer
- in OpenVZ, is there any monitor script, that will release an email to say one VPS is down? Or will I need to use external monitoring?
- can I do the backup / restore of full VPS within OpenVZ? Can customers do it themselves?
- how hard to change the VPS configuration? For example, upgrading from 256MB RAM to 512MB RAM, or adding more CPU, space...?
- how about the IP control in OpenVZ? Let's say each VPS will have 2 IPs, so to prevent customers adding more IPs, I will need to setup VLAN, is that correct? How hard is it in OpenVZ?
- how about the ideal hardware for running OpenVZ? Saying SATA, or SCSI disks, how many RAM... for example
