Chapter 8. Master Feature

Administering PSA managed slave servers

PSA Master - the Plesk Server Administrator software with Master feature enabled (defined by the PSA key license) allows the Administrator to set some specific PSA server to function as PSA master server.

Provided that there are a number of PSA servers networked, the feature empowers Administrator to log on to other PSA slave servers, manage them remotely and monitor the detailed PSA slave servers status information from a single point of entry - a PSA master server control panel.

As an administrator using the Plesk Server Administrator (PSA) software, you can perform a variety of slave server management tasks in a few clicks. When you are logged on as an administrator, click the MASTER button located at the top of the screen to bring up the Slave Servers Administration page. From this page, you can access the following functions:

  • Adding a slave server account

  • Editing a slave server profile

  • Logging on to a slave server

On the Slave Servers Administration page you can view the list of all the PSA slave servers networked and manage slave server accounts. After you have added a new PSA slave server account, it will be displayed in the list on this page.

The status of a slave server will be indicated by a colored icon:

  • [OK] means that the slave server is alright

  • [!] (red) is displayed when some system service is experiencing problems

  • [!] (yellow) is displayed if there are problem clients or domains on the slave server

  • [X] is displayed if the server is down or disabled

  • [?] is displayed if the server information is not requested

PSA allows you to search through the list of slave servers for a certain pattern. It may help you in case you have a great number of slave servers accounts registered in the system and you need to work with a particular one. To search in the Servers List:

  1. Select the input field and type in the pattern string.

  2. Click the SEARCH button.

  3. If there were any items found matching the pattern string entered, they will all be displayed in the form of the reduced Servers List.

  4. If no matches were found it will be so stated.

  5. The button SHOW ALL will revert to displaying the whole list of slave server accounts.

You can also sort the list of slave server accounts by Status, Hostname and Description. To sort the list by a certain parameter in ascending or descending order, click on the name of the parameter. An arrow will appear indicating the order of sorting: down for descending order, up for ascending.

You can send an e-mail message to administrator of a slave server. To do that put a check mark in the appropriate checkbox in the Sel column, click SEND MAIL.

Logging on to a slave server

To log on to a slave server:

  • In the Slave Servers Administration page: click on the "Log on to the slave server" icon relating to the appropriate slave server. The PSA control panel of the remote slave server the will open in a new browser window.

  • You may also click the button LOG IN in the Slave server profile. The PSA control panel of the remote slave server will open in a new browser window.

  3. Enter the hostname and port number in the appropriate fields, enter login name, and password for Plesk Server Administrator to be able to log on to the given slave server. You may also wish to type in a description for the slave server. Check the Do not request information from the server checkbox, if you do not wish the detailed slave server information to be displayed.

  4. Click SET.

The Slave server profile page will be updated with the following slave server information: Key number, OS, PSA version, CPU type, System Uptime, Load averages for last 1, 5, 15 minutes, number of clients, number of problem clients, number of domains, number of problem domains, number of databases, number of database users, web users, mail autoresponders, mail groups, mail redirects, mail boxes, active domains, domains with hosting, and status of services.

  6. To manage certificate for the server click on the CERTIFICATE button. You will be taken to Slave server certificate management page. You can copy and paste the certificate content right into appropriate field or simply browse to its location by clicking on the Browse... button. After that, click on SEND FILE or SEND TEXT buttons respectively to submit the certificate, or click on the UP LEVEL button to discard any changes and return to the Slave server profile page.
