Endpoint running a Linux (RHEL/CentOS, Debian/Ubuntu, SUSE) with zLink package installed
Port 443 outbound
Port 22 inbound (if you don't have access to the physical server or the host machine of your VM or Container)
Root privileged account on the targeted Linux host
What will Happen During Upgrade:
During the upgrade, the endpoint connection will be closed. If users are using zAccess solution, make sure all the work on zAccess server are saved as the remote access session will be closed during the upgrade.
Case 1: If zLink is currently offline or incompatible with the new release, please follow the steps below.
Login to zCenter and go to "Project Provisioning" and then "zLink Packages" page.
Download both "zLink Dependency Package" and "zLink Package" for the targeted endpoint with correct OS architecture. The zLink dependency package is called "zasa-dep.x86_64.rpm" or alike and the zLink package is "install_zlink.tar.gz" or alike.
Transfer both packages to the endpoint and place them in /tmp/zentera/.
With a terminal access to the endpoint host, do the following if the package is RPM based:
$ cd /tmp/zentera
$ tar zxf install_zlink.tar.gz
$ sudo rpm -Uvh zasa-dep.x86_64.rpm --nodeps
$ sudo rpm -Uvh zasa.x86_64.rpm --nodeps
$ sudo service zasad status
The last command in the previous step will show the status of zLink.
Case 2: If zLink is currently online and registered to zCenter, please follow the steps below.
Find your target server pool in Cloud Server Pools under Project Provisioning in your target zCenter
Click on "Cloud Servers" to the right of target server pool
Select the host to upgrade and click the upward arrow at the bottom of the list for "Auto-upgrade Selected zLink"
zLink Version for the selected host(s) will show the new version number with a current time in the "Online Since" column.
