ローカル環境でCassandraマルチノード起動 |
OS : MacOSX Lion
Cassandra : 1.0.x
1. IP loopback alias 追加
$ sudo ifconfig lo0 alias 127.0.0.2
$ sudo ifconfig lo0 alias 127.0.0.3
$ ifconfig
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
options=3<RXCSUM,TXCSUM>
inet6 fe80::1%lo0 prefixlen 64 scopeid 0x1
inet 127.0.0.1 netmask 0xff000000
inet6 ::1 prefixlen 128
inet6 fd76:4a17:61aa:f7df:60c:ceff:fee2:adb2 prefixlen 128

2. Cassandraインスタンスを３つ作成
3. １つ目の設定
- conf/cassandra.yaml
| cluster_name: 'BABUKUMA Cluster' # directories where Cassandra should store data on disk.
data_file_directories:
- /Users/babukuma/Public/tmp/1_cassandra/data
# commit log
commitlog_directory: /Users/babukuma/Public/tmp/1_cassandra/commitlog
# saved caches
saved_caches_directory: /Users/babukuma/Public/tmp/1_cassandra/saved_caches
seed_provider:
# Addresses of hosts that are deemed contact points.
# Cassandra nodes use this list of hosts to find each other and learn
# the topology of the ring. You must change this if you are running
# multiple nodes!
- class_name: org.apache.cassandra.locator.SimpleSeedProvider
parameters:
# seeds is actually a comma-delimited list of addresses.
# Ex: "<ip1>,<ip2>,<ip3>"
- seeds: "127.0.0.1"
listen_address: 127.0.0.1
rpc_address: 127.0.0.1

| JMX_PORT="7199" |
- conf/log4j-server.properties
| log4j.appender.R.File=/Users/babukuma/Public/tmp/1_cassandra/logs/system.log |

6. ディレクトリ作成
data, commit log, saved cache, log用のディレクトリ
7. 起動して確認
$ ./1_apache-cassandra-1.0.0/bin/cassandra -f &
$ ./2_apache-cassandra-1.0.0/bin/cassandra -f &
$ ./3_apache-cassandra-1.0.0/bin/cassandra -f &
$ ./1_apache-cassandra-1.0.0/bin/nodetool -h 127.0.0.1 ring
