Follow these steps:
- First, download the update repo zip (e.g. for 6.0 U3A, the filename is VMware-vCenter-Server-Appliance-6.0.0.30100-5202501-updaterepo.zip )
- Transfer the updaterepo zip to a PSC or VCSA that will be used as the server. You can use Putty's pscp.exe on Windows or scp on Mac/Linux, but you'd have to run "chsh -s /bin/bash root" in the CLI shell before using pscp.exe/scp if your PSC/VCSA is set up with the appliancesh.
- chsh -s /bin/bash root
- "c:\program files (x86)\putty\pscp.exe" VMware*updaterepo.zip root@psc-name-or-address:/tmp
- Change your PSC/VCSA root access back to the appliancesh if you changed it earlier:
- chsh -s /bin/appliancesh root
- Make a directory for the repository files and unpack the updaterepo files there:
- mkdir /srv/www/htdocs/6u3
- chmod go+rx /srv/www/htdocs/6u3
- cd /srv/www/htdocs/6u3
- unzip /tmp/VMware-vCenter*updaterepo.zip
- rm /tmp/VMware-vCenter*updaterepo.zip
- Create a redirect using the HTTP rhttpproxy listener and restart it
- echo "/6u3 local 7000 allow allow"> /etc/vmware-rhttpproxy/endpoints.conf.d/temp-update.conf
- /etc/init.d/vmware-rhttpproxy restart
- Create a /tmp/nginx.conf (I didn't save mine, but "listen 7000" is the key change from the default)
- Start nginx
- nginx -c /tmp/nginx.conf
- Start the update via the VAMI. Change the repository URL in settings, use http://psc-name-or-address/6u3/ as repository URL. Then use "Check URL".
- Afterwards, clean up:
- killall nginx
- cd /srv/www/htdocs; rm -rf 6u3
P.S. I personally tested this using a PSC as webserver to update both that PSC, and also a VCSA appliance.
P.P.S. VMware released an update for VCSA 6.0 and 6.5 on the day I wrote this. For 6.0, the latest version is U3B at the time of writing, while I updated to U3A.
