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
