How to install 2 NSO on the same server ?

[tberthe.ext]

In order to use LSA, we would like to install 2 NSO instances on the same server.

Is it possible to have 2 NSO system installs at the same time ?

Absolutely, you have to modify ncs.conf to avoid port collisions though, please take a look at <NSO dir>/examples.ncs/getting-started/developing-with-ncs/22-layered-service-architecture

which contains exactly what you're looking for and it runs three NSO on one machine.

Hello,

For local install you need to configure NCS_IPC_PORT differently for the 2 instance...

See the Makefile at the top level of the LSA example in the NSO distribution which creates 3 NSO instances on same serve:

nso-4.5.2/examples.ncs/getting-started/developing-with-ncs/22-layered-service-architecture

<snip>

start:

    ncs-netsim start

    cd upper-nso;   NCS_IPC_PORT=4569 sname=upper-nso ncs -c ncs.conf

    cd lower-nso-1; NCS_IPC_PORT=4570 sname=lower-nso-1 ncs -c ncs.conf

    cd lower-nso-2; NCS_IPC_PORT=4571 sname=lower-nso-2 ncs -c ncs.conf

    ./init.sh

I don't believe it is possible to have 2 NSO system-installs on Linux server.
