Cassandra的安装

1.上传安装包到node01

cd /export/softwares

 

 

2.解压

tar -zxvf apache-cassandra-3.11.5-bin.tar.gz -C ../servers cd ../servers mv apache-cassandra-3.11.5 cassandra-3.11.5

 

 

3.新建文件夹

#进入servers目录 cd /export/servers #新建以下文件 mkdir -p /export/servers/cassandra-3.11.5/cassandra/data mkdir -p /export/servers/cassandra-3.11.5/cassandra/saved_caches mkdir -p /export/servers/cassandra-3.11.5/cassandra/commitlog mkdir -p /export/servers/cassandra-3.11.5/cassandra/hints mkdir -p /export/servers/cassandra-3.11.5/cassandra/logs

 

 

 

4.备份并修改cassandra.yaml

#进入conf目录 cd /export/servers/cassandra-3.11.5/conf #复制文件 cp cassandra.yaml cassandra.yaml.back #修改文件 vim 或notepad++

 

 

修改文件

cluster_name: 'cassandracluster' hints_directory: /export/servers/cassandra-3.11.5/cassandra/hints data_file_directories:      - /export/servers/cassandra-3.11.5/cassandra/data saved_caches_directory: /export/servers/cassandra-3.11.5/cassandra/saved_caches commitlog_directory: /export/servers/cassandra-3.11.5/cassandra/commitlog

 

5.分发安装包

#进入servers目录 cd /export/servers   #分发安装包 scp -r cassandra-3.11.5 node02:$PWD scp -r cassandra-3.11.5 node03:$PWD

 

6.在node02、node03上新建文件夹

#进入servers目录 cd /export/servers #新建以下文件 mkdir -p /export/servers/cassandra-3.11.5/cassandra/data mkdir -p /export/servers/cassandra-3.11.5/cassandra/saved_caches mkdir -p /export/servers/cassandra-3.11.5/cassandra/commitlog mkdir -p /export/servers/cassandra-3.11.5/cassandra/hints mkdir -p /export/servers/cassandra-3.11.5/cassandra/logs

 

7.修改node02、node03上的配置文件cassandra.yaml

 

 

 

8.启动Cassandra

cd /export/servers/cassandra-3.11.5/bin cassandra -R
