How do I enable single-address DR NSP system access?
Purpose
Use this procedure to reduce the number of IP addresses a user requires for access to the NSP clusters in a DR NSP deployment.
The procedure describes implementing a reverse proxy that presents only one IP address for system access. The reverse proxy maps the IP address to the appropriate NSP cluster.
Note: The procedure describes using the mod_proxy Apache HTTP module. Using a different proxy agent or mod_proxy configuration is supported but not described. Also, mod_proxy installation is not described. Reverse proxy implementation is specific to a network; the network administrator must determine which implementation is best suited to the management network.
Steps
1 |
Log in as the root user on the station that is to host the reverse proxy. |
2 |
Open a console window. |
3 |
Open the httpd.conf file in the mod_proxy installation directory using a plain-text editor such as vi. |
4 |
Edit the file to include the following: <VirtualHost *:*> <Proxy nspOS://dr> BalancerMember http://NSP1 BalancerMember http://NSP2 </Proxy> ProxyPreserveHost Off ProxyPass / nspOS://dr/ ProxyPassReverse / nspOS://dr/ </VirtualHost> where NSP1 and NSP2 are the advertised addresses of the NSP clusters |
5 |
Close the console window. End of steps |
