安裝參考
http://wiki.apache.org/cassandra/GettingStarted
下載
http://cassandra.apache.org/download/
http://apache.stu.edu.tw/cassandra/2.0.3/apache-cassandra-2.0.3-bin.tar.gz
需要 Java 7，建議 Oracle/Sun JVM，但 OpenJDK 和 IBM JVM 也可以用
設定檔為 conf/cassandra.yaml
資料庫存放在 /var/lib/cassandra/data/
logs 在 /var/log/cassandra/.
(一) 單一節點安裝
setenforce 0
service iptables stop
# wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F" "http://download.oracle.com/otn-pub/java/jdk/6u45-b06/jdk-6u45-linux-x64.bin" -O jdk-6u45-linux-x64.bin
wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F" "http://download.oracle.com/otn-pub/java/jdk/7u45-b18/jre-7u45-linux-x64.rpm" -O jre-7u45-linux-x64.rpm

rpm -ivh jre-7u45-linux-x64.rpm
export JAVA_HOME=/usr/java/jre1.7.0_45/
alternatives --install /usr/bin/java java /usr/java/jre1.7.0_45/bin/java 100
alternatives --config java
wget http://apache.stu.edu.tw/cassandra/2.0.3/apache-cassandra-2.0.3-bin.tar.gz
tar zxvf apache-cassandra-2.0.3-bin.tar.gz -C /usr/local
sudo mkdir -p /var/log/cassandra
sudo chown -R `whoami` /var/log/cassandra
sudo mkdir -p /var/lib/cassandra
sudo chown -R `whoami` /var/lib/cassandra
#啟動
/usr/local/apache-cassandra-2.0.3/bin/cassandra
交談命令介面
/usr/local/apache-cassandra-2.0.3/bin/cassandra-cli
(二) 多節點安裝
假設兩台電腦 IP 分別 192.168.128.101 和 192.168.128.102
都先照單節點安裝，測試成功後，把兩台的 cassandra 都停止
停止 Cassandra，找出 PID 用 kill -9 指令刪除
ps aux | grep cassandra
kill -9 找到的PID
或直接用下面命令
kill `ps aux | fgrep $USER | grep cassandra | grep -v 'grep' | awk '{print $2}'`
編輯設定檔案
vi /usr/local/apache-cassandra-2.0.3/conf/cassandra.yaml
把
- seeds: "127.0.0.1"
改為
- seeds: "192.168.128.101,192.168.128.102"
(兩台都這樣改，把兩台的 IP 放入 seeds 值中)
把
listen_address: localhost
改為自己的 IP
第1台改為
listen_address: 192.168.128.101
第2台改為
listen_address: 192.168.128.102
兩台都啟動 Cassandra
/usr/local/apache-cassandra-2.0.3/bin/cassandra
確認執行成功
[root@localhost ~]# ps aux | grep cassandra

root 28736 0.0 0.0 103252 840 pts/1 S+ 06:22 0:00 grep cassandra
[root@localhost ~]#
檢視開了那些 port
[root@localhost ~]# netstat -anp | grep LISTEN | grep java
tcp 0 0 0.0.0.0:43853 0.0.0.0:* LISTEN 28213/java

[root@localhost ~]#
測試，結果應該會列出兩台主機
1.2.8版使用下面指令，這在2.0.3版會報錯
[root@localhost ~]# /usr/local/apache-cassandra-2.0.3/bin/nodetool -h localhost ring
....
ERROR 06:28:33,470 Unable to initialize MemoryMeter (jamm not specified as javaagent). This means Cassandra will be unable to measure object sizes accurately and may consequently OOM.
Warning: "nodetool ring" is used to output all the tokens of a node.
To view status related info of a node use "nodetool status" instead.
2.0.3 版指令要這樣用
[root@localhost ~]# /usr/local/apache-cassandra-2.0.3/bin/nodetool status
或
[root@localhost ~]# /usr/local/apache-cassandra-2.0.3/bin/nodetool -host 127.0.0.1 -p 7199 status
