Here's the list of commands I've used to run various processes (logcabin, coordinator, master) on various nodes on RAMCloud. Keeping them around for ease of use.

 

LogCabin:
I typically run the logcabin cluster on rc10, rc09, rc08.
I have scripts do-clean-initialize and do-reconfigure in ~/ramcloud/logcabin to make life a little easier. You can copy these to your logcabin directory. Alternately, you can follow the instructions in Additional notes -> LogCabin.

 

on some node x (doesn't matter which, so lets say rcmaster):
cd logcabin
./do-clean-initialize

on all nodes on which i want to run the logcabin cluster:
cd logcabin
./build/LogCabin

on x:
./do-reconfigure

 

Coordinator: on rc11:
./obj.master/coordinator -C "infrc:host=192.168.1.111,port=11114" -z "logcabin06:61023" -l "DEBUG"

 

Masters: on rc01 through rc06 (each command corresponds to each node):
./obj.master/server -L "infrc:host=192.168.1.101,port=11113" -C "infrc:host=192.168.1.111,port=11114" -M r=0
./obj.master/server -L "infrc:host=192.168.1.102,port=11113" -C "infrc:host=192.168.1.111,port=11114" -M r=0
./obj.master/server -L "infrc:host=192.168.1.103,port=11113" -C "infrc:host=192.168.1.111,port=11114" -M r=0
./obj.master/server -L "infrc:host=192.168.1.104,port=11113" -C "infrc:host=192.168.1.111,port=11114" -M r=0
./obj.master/server -L "infrc:host=192.168.1.105,port=11113" -C "infrc:host=192.168.1.111,port=11114" -M r=0
./obj.master/server -L "infrc:host=192.168.1.106,port=11113" -C "infrc:host=192.168.1.111,port=11114" -M r=0

 

Additional notes:

LogCabin (description of each step + the non-short version without using scripts):

 

1. to delete initialization / data from previous run:
rm -r log

2. initializing logcabin (with first member on rc10):
./scripts/initlog.py --serverid=1 --address=192.168.1.110:61023

3. now start all the servers (including the first member with which i had initialized, and the ones that will be added during the reconfiguration) by doing this on each of them:
./build/LogCabin

4. to reconfigure with more servers:
make sure other servers i want to add are up and running (step above)
on some machine:
./build/Examples/Reconfigure -c logcabin06:61023 192.168.1.110:61023 192.168.1.109:61023 192.168.1.108:61023
