cassadra 安裝

1.下載：

apache-cassandra-2.0.6-bin.tar.gz

jdk-8-linux-x64.rpm


2.先更新jdk

?? ?rpm -ivh jdk-8-linux-x64.rpm

?? ?修改java ，指定到最新版本


?? ?rm /usr/bin/java? java.bak
?? ?ln -s /usr/java/jdk1.8.0/bin/java java

?? ?[root@localhost bin]# java -version
?? ?java version "1.8.0"
?? ?Java(TM) SE Runtime Environment (build 1.8.0-b132)
?? ?Java HotSpot(TM) 64-Bit Server VM (build 25.0-b70, mixed mode)



3.安裝cassandra



[root@localhost backup]# tar zxvf? apache-cassandra-2.0.6-bin.tar.gz

[root@localhost backup]# cd apache-cassandra-2.0.6/bin

root@localhost bin]# ll cassandra
-rwxr-xr-x 1 mongo mongo 7108 3月?? 7 20:34 cassandra
[root@localhost bin]# ./cassndra
-bash: ./cassndra: 沒有那個文件或目錄
[root@localhost bin]# ./cassandra
[root@localhost bin]#? INFO 17:59:33,186 Logging initialized
?INFO 17:59:33,369 Loading settings from file:/opt/backup/apache-cassandra-2.0.6/conf/cassandra.yaml

Cassandra集群 實施方案：

兩個節點：192.168.10.104
?? ?? 192.168.10.206


相關的JAVA，cassandra 安裝不再累述。兩節點的配置安裝和上面的是一樣的。
下面來做相關配置文件的修改：



節點1：
?? ? ?
?? ?192.168.10.104


?? ?vi /opt/apache-cassandra-2.0.6/conf/cassandra.yaml

?? ?修改內容如下：

?? ?cluster_name: 'Cluster1'

?? ? - seeds: "192.168.10.104"

?? ?listen_address: 192.168.10.104




節點2：
?? ? ?
?? ?192.168.10.206


?? ?vi /opt/apache-cassandra-2.0.6/conf/cassandra.yaml

?? ?修改內容如下：

?? ?cluster_name: 'Cluster1'

?? ? - seeds: "192.168.10.104"

?? ?listen_address: 192.168.10.206



啟動

經檢查，發現防火墻開著，兩節點一直無法連接上。在修改防火墻后，終于成功解決問題。
查看集群狀態如下：

?[root@localhost bin]# ./nodetool -h 192.168.10.206 ring

測試：

1.在 206 節點創建 keyspace,并插入數據：


[root@localhost bin]# ./cassandra-cli -host 192.168.10.206
Connected to: "Cluster1" on 192.168.10.206/9160
Welcome to Cassandra CLI version 2.0.6

2.在節點2查看數據：

[root@localhost bin]# ./cassandra-cli -h 192.168.10.104
Connected to: "Cluster1" on 192.168.10.104/9160

可以看到，數據已同步過來了。
