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 (by me and others (mainly / specially Stephen)).
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.
Before the first time you run this, you have to do the setup (step 0) described below in Additional notes -> LogCabin.
on some node x (doesn't matter which, so lets say rcmaster):
cd logcabin
./do-clean-initialze
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):
0. setup
in logcabin/Examples/Reconfigure.cc:
- change the cluster address according to the group of machines i'm using (logcabin01, logcabin06, and so on)
- put the right addresses for the servers to be added
My current settings for various parts are (assuming i will be starting the logcabin instance first on rc10, followed by rc09 and rc08, in no particular order):
Cluster cluster("logcabin06:61023");
and
servers.emplace_back(2, "192.168.1.109:61023");
servers.emplace_back(3, "192.168.1.108:61023");
1. to forget 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:
scons (to compile Reconfigure.cc)
./build/Examples/Reconfigure
