Understanding the Manager Software
This article provides information about the Manager software, details about the Manager version, details about the App Connector and Private Service Edge software versions, and upgrades to all.
When you first deploy an App Connector or Private Service Edge, a server is required to run the software. The server is available using a virtual machine (VM). The VMs run a service called zpa-connector for App Connectors and zpa-service-edge for Private Service Edges. To learn about installing the service on your own server, see the App Connector Deployment Guides for Supported Platforms and Private Service Edge Deployment Guides for Supported Platforms.
The Manager is the zpa-connector or zpa-service-edge software that is needed to manage the App Connector or Private Service Edge components.
The zpa-connector software downloads a new software, called zpa-connector-child, that establishes Microtunnels (M-Tunnels) and talks to the internal applications. This child software facilitates access to internal applications for Private Application users.
Manager Version and Current Software Version
The purpose of the Manager software is to supervise and control the App Connector (zpa-connector-child) or Private Service Edge (zpa-service-edge-child) software. The version of the manager rarely requires updates. New features are constantly being added to Private Applications and these features involve new functionality in App Connectors or Private Service Edges. The App Connector software (zpa-connector-child) does the primary work of the App Connector and gets updated frequently.
The manager software uses the OS trusted Certificate Authority (CA) bundle for establishing a TLS connection to download software. The CentOS CA bundle can be found at the following location: /etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem
Use the following command to update the CentOS CA bundle: sudo update-ca-trust
Manager, App Connector, and Private Service Edge Upgrades
The Manager software is what makes the upgrades possible.
- Manager Upgrades
The Manager upgrades mean upgrading the
zpa-connectororzpa-service-edgesoftware. If you are using Linux software packages, the Manager must be upgraded manually in your App Connector or Private Service console using the following command:sudo yum upgrade
This command upgrades all software packages on the server, including
zpa-connectorandzpa-service-edge, which holds the Manager software.To upgrade only the
zpa-connectorpackage, use the following command:sudo yum upgrade zpa-connector
To upgrade only the
zpa-service-edgepackage, use the following command:sudo yum upgrade zpa-service-edge
Both commands include the upgrade of the Manager software.
The Manager software is included in upgrades to the App Connector or Private Service host operating system (OS). Zscaler recommends periodically updating the App Connector or Private Service host OS using the
Closesudo yum update -ycommand. To learn more, see Upgrading the App Connector Host OS. - App Connector Upgrades
App Connector upgrades mean upgrading the
Closezpa-connector-childsoftware. To learn more, see Understanding App Connector Software Upgrades. - Private Service Edge Upgrades
Private Service Edge upgrades means upgrading the
Closezpa-service-edge-childsoftware. To learn more, see Understanding Private Service Edge Software Upgrades.
