vCenter 5.1 U1 Installation: Part 7 (Install vCenter Server 5.1)

If you’ve made it this far, congrats! We are now ready to Install vCenter Server 5.1 Update 1! Yes in vSphere 5.1 there is A LOT of prerequisite work to do before you can start the vCenter Server installation. Part 6 of my series showed how to configure the vCenter and VUM SQL databases and the vCenter DSN. Now that all of the pre-reqs have been completed, we can now install vCenter Server 5.1 Update 1!

Before we get started, listed below are the other related articles in this series:

Part 1 (SSO Service)
Part 2 (Create vCenter SSL Certificates)
Part 3 (Install vCenter SSO SSL Certificate)
Part 4 (Inventory Service Install)
Part 5 (Inventory Service SSL Certificate)
Part 6 (Create vCenter and VUM Databases)
Part 8 (Install Web Client)
Part 9 (Optional SSO Configuration)
Part 10 (Create VUM DSN)
Part 11 (Install VUM)
Part 12 (VUM SSL Configuration)
Part 13 (VUM Configuration)
Part 14 (Web Client and Log Browser SSL)
Part 15 (ESXi Host SSL Certificate)

UPDATE 4/28/2013: I removed the SSL certificate pre-population steps, as using the VMware vCenter Certificate Automation tool is a much better option. You do that post-install, after all the components have been installed with self-signed certificates.

Install vCenter Server 5.1 Update 1

1. In Part 1 I created a service account that the SSO service used, and for the sake of simplicity I’ll use the same service account for the vCenter Server service. Login to your vCenter server as the service account. It should already have local admin rights on the vCenter server. Launch the vSphere 5.1 installer menu and select VMware vCenter Server and start the installation.

2. Select the appropriate language, read through all of the patents, EULA, and enter a license key if you have one.

3. On the Database Options screen you should select the second option then, if all went well, find your vCenter DSN from the drop-down menu.

4. Since we are using Windows authentication to the SQL server (more secure than SQL authentication) you can’t ender a database username or password.

5. You will likely see this warning message about the SQL database in full recovery mode, and that it may consume a lot of disk space without regular backups. This is normal and do NOT be alarmed. You ARE doing regular SQL backups right?

6. If you are running the installation as the vCenter service account (which you should be), then the account name will be pre-populated and you need to enter the appropriate password.
7. We don’t need to join an existing Linked mode group, so standalone is fine.

8. All of the default port numbers are fine, and for small environments we don’t need to increase the number of available ephemeral ports. If you will be powering on more than 2,000 VMs, then check the box.

9. JVM memory is an important configuration parameter, so carefully choose the right value. It doesn’t hurt to select a larger value, assuming you have adequate memory assigned to the vCenter VM.

10. New to vSphere 5.1 is the SSO service, so we need to input the master password used during the SSO installation process which I covered in part 1. The wizard will validate the password.

11. At this prompt you need to enter the group or user that will be recognized by the SSO service as the vCenter administrator. If you installed the SSO service in High Availability mode, then you will probably get an error “Wrong Input – either a command line argument is wrong….” if you try and use the “Administrators” group. So I would create an AD group that you want to use. Following my RBAC naming convention I specified the appropriate AD group. Use whatever group name you wish. The wizard will validate that it exists.

Note: If you get suck at this point in the installer, check out the reader feedback below. Ben Hicks and John have some great tips on possible solutions.

12. Next you should see the vCenter Inventory Service URL, which needs no modifications.
13. Change the installation path if you wish, but I left it the default value. Then click Install and wait for it to complete. Profile Driven install may take a loooong time to install…20 minutes or more. So be patient while the installer runs.

14. Per a VMware KB article you need to fix the ADAM SSL port registry type. To fix this issue navigate to:


Delete the Port SSL key and recreate it as a 32-bit DWORD with a decimal value of 636.   Note: Per reader feedback, if you are using Linked Mode, use a different port number (above 1025) for the Port SSL, otherwise there will be a conflict.

Assuming a successful installation, you can proceed to Part 8, where we install the vSphere Web Client.

Excellent to know! I’m trying a fresh install as well, each with different certs from my 2008 R2 CA. I’ll see how that goes!

Terafirma, yes now that you point that out, I found that in the VMware PKI Guide. I’ll amend my post.thanks for catching that!

September 18, 2012 7:51 pm

Got Web-Client going turned out to be just not waiting long enough for the service to start and compile its keystore. (me getting frustrated and impatient)

Only annoying thing is Web-Client can only have its cert updated by putting it in the ProgramData\vSphere Web Client\SSL\ folder before install as the register-sso scripts that VMware reference don’t actually exist!!

I must say VMware really dropped the ball on SSL certs this release bring on vCertManager from Michael Webster

All that is left now is Orchestrator.

thanks for your documnet. I try the best from your doc and it come to the vsphere server installation almost done the system come up the error 26002 setup fail to register VMware vCenter server to VMwar vCenter Inventory Service. I wonder you see this error before. need some help. Thank again!

September 22, 2012 10:38 am

Anonymous: Yes, I’ve run into the exact same problem and have an open case with VMware tech support. There is wide spread frustration in the community with trying to get SSL certs working. For now I’d skip the trusted SSL certificate generation and go with the vanilla install. As reliable solutions emerge I’ll update my posts with better instructions.

Anonymous, you can work around the 26002 setup failure by skipping Part 5, replacing the Inventory service SSL certificate. You can replace the SSO certificate and the install will continue as one would expect. I’ll keep researching the Inventory service SSL problem.

How do I change the vCenter SSL certificates?
Using custom SSL certificates in vCenter 5.1 is fucking pain.

October 7, 2012 10:55 am

Hi Derek, appreciate all your patience & time in writing these great posts! Just a quick question from my end: Our’s is a small environment running with Vcenter 4.1, SQL 2005 express & Six ESX 4.1 hosts.

Planning to perform inplace upgrade of vCenter 4.1 to 5.1 using Simple Install Option & SQL 2008 R2 Express (bundled along with vCenter). Do you think it should be straight forward or any hiccups which I need to work on before proceeding..? Thanks for your time!

Reply to  Ashok

I haven’t done in-place upgrades, and given the problems with 5.1, I would expect some hiccups. VMware is rumored to be releasing an update of some time this month to address the SSL problems. So personally I’d wait on the patch/update before upgrading. If your vCenter/SQL/Etc are on one VM, then just snapshot the VM and see how the upgrade goes. If it goes south, just unsnapshot.

October 12, 2012 6:28 am

Derek, how do you log into the machine with service account as that account was supposed to be just for services and shouldn’t be able to log-in? I can’t make it work…


Reply to  Anonymous

A service account is no different from a regular user account in AD. The service account must have local admin rights on the vCenter server. So once you put the service account in the local admins group on the vCenter server, you should be able to login with no problem.

October 15, 2012 12:05 am

i have added the administrator as a single user in step 11, and modified the _administrators_ group and added other AD accounts to it, but the users cannot login neither to the vSphere client nor to the web client.
how can i modify the users in the administrator (under SSO users and groups) role or create a new role with admin privileges and add the users to it.
please help and advice.

Thank you for your extensive instructions on how to install the new vCenter server 5.1. They have been very helpfull to me. Specially after one of my production vCenter servers crashed last weekend. With the exact same symptoms as the test vCenter server that crashed after replacing the SSL certificates. An empty VPX_ACCESS table and a vCenter server service that would start and immediately stop. Even though I didn’t touch the certificates, I just patched and rebooted it. I managed to fix it, by reinstalling the vCenter server service and changing the default admin group added and the default SSL… Read more »

Hi Derek,

Great tutorial. I have a quick question. After finishing vcenter installation I couldn’t start the service. I’ve found the following error message:

Do you have any ideas?

@Mark: I would review the certificate files and ensure they have the proper start/end headers. Sounds like malformed certificates to me.

I had the exact same error and even opened a case with VMware, but I have managed to fix this myself. Following every guide I could find they kept saying to use Openssl-Win32. I tried several times to create the certificates and it kept giving me this error. I ended up humouring myself and installing OpenSSL-Win64 1.0.1c and low and behold, vCenter now happily accepts the pre-staged SSL Certificates. Give that a try, might work for you. I am still battling with the vSphere Web Client tho. I keep getting the yellow warning: Failed to verify the SSL certificate for… Read more »

A lesson learned: I received the dreaded Error 26002 error during my first install even when using the newer version of the vCenter install media. In my case the issue seems to have been caused by having the Web Server Role installed on the server. I know you’re not supposed to have IIS on the box but I had the default web site stopped and disabled so I assumed it wouldn’t conflict. Apparently it conflicts anyway, because the only way I was able to successfully install vCenter was to remove the Web Server role completely from the server. It is… Read more »

December 13, 2012 5:40 am

About Error 26002. I got it as well although I followed all instructions in your great posts. After some hair polling it turns out that vCenter Server, unlike all other components, doesn’t like certificates that have any text before the start certificte marker. If you sign your certificate requests using openssl ca like I do then by default openssl adds the text form of the certificate before the encoded form in the resulting rui.crt file. To get around this either edit the certificate in notepad and remove all the text before the start certificte marker. Or better yet add the… Read more »

I have just managed to resolved this issue. When trying to install vCenter server, I was getting the “does not exist error”. I tried everything to resolve this with regards to formatting of names / local vs domain users and groups but to no avail. The solution was to install the web client before vCenter. Once you have the web client installed, you login as your admin@system-domain user and go to “Sign-on and discovery” and then configuration. You need to add an identity source that corresponds to your domain. Put in a domain controller server with the format of ldap://fqdn… Read more »

Hi John / Derek, The install tip came direct from VMware tech support. I think the issue came about (in my case) from an incorrect reverse look-up on the VMs IP address. During the installation – it throws up an error about not being able to correctly resolve and that it may cause problems. My guess is that it uses the PTR record to locate the local domain name and from there a domain controller. If the look-up works correctly, this information is populated and the web client installation is not needed. Either way, once this was all completed I… Read more »

I had used your 15 part doc earlier to create a VC5.1 installation with a MS CA assigned cert., Now I am doing a VC 5.1 Update1 install however I want to follow the manual process. I tried the VMware Tool and it got stuck half way making me start all over again. I see that on April 28th you updated the post and removed the pre-population of SSL Certs for Vcenter and VMware WebClient. Is it possible that I can access the older post somewhere with the steps.

Hey Derek, I wanted to follow up with you. Since VMware's release of the SSL tool, the suggestions I mentioned in this posted about installing the client, making the necessary SSO changes, then installing vCenter Server was not needed in my case.

I guess some things changed in the back end of this vCenter release to no longer warrant configuring SSO through the web client then installing vCenter.

Thanks for keeping everybody in the loop with VMware's releases!
