Central Management across multiple VPS - Virtual Private Servers
NGASI AppServer Manager supports Parallels Virtuozzo as well as its open source
derivative OpenVZ. As the administrator, you have the option of centrally deploying a
single NGASI AppServer Manager in the Host or Node system to manage multiple
VPSs (VEs) or NGASI AppServer Manager may be installed in each VPS (VE).
The latter is not recommended as resources (such as RAM) is limited in VPSs (VE)
so it would be better install NGASI AppServer Manager in the Host (Node) system.
When installed centrally, NGASI AppServer Manager is able to retrieve VPS (VE)
specific information such as system users and Control Panel user information required
for setup and management for NGASI. For Hypervisor based VPS such as
VMWare and XEN, refer to the Remote Servers section.
NOTE: In order to run java in a VPS, at least 256MB RAM (per JVM) must be allocated to the VPS system.
Plesk
For Plesk under a Guest VPS (VE) managed by NGASI AppServer Manager installed
in the Host (Node) System, access to the VPS (VE) Plesk Database must be made
available connecting from the Host (Node) system. If NGASI AppServer Manager is
already started after access has been provided, you must restart
NGASI AppServer Manager. The Plesk DB user must be the default "admin",
and the password should be in the default location,
/etc/psa/.psa.shadow.
To grant Access:
Login to the VPS
Login to MySQL with the Plesk mysql admin info, and insert the following statement:
GRANT DELETE,INSERT,UPDATE, SELECT,INDEX,REFERENCES,LOCK TABLES, CREATE TEMPORARY TABLES ON psa.* TO admin@"%" IDENTIFIED BY 'passwd';
Replace "passwd" with the same password found in /etc/psa/.psa.shadow.
Make sure NGASI AppServer Manager is restarted.
Please refer to the "Plesk" topic in the "Control Panels" section.
