Cassandra（一）之linux中的下載下傳和安裝

Cassandra（一）之linux中的下載下傳和安裝

1、建立cassandra.repo檔案

touch /etc/yum.repos.d/cassandra.repo
           

2、配置cassandra.repo

vi /etc/yum.repos.d/cassandra.repo
           

[cassandra]
name=Apache Cassandra
baseurl=https://www.apache.org/dist/cassandra/redhat/311x/
gpgcheck=1
repo_gpgcheck=1
gpgkey=https://www.apache.org/dist/cassandra/KEYS
           

3、安裝

sudo yum install cassandra
           

4、啟動Cassandra

service cassandra start
           

5、設定随機啟動Cassandra服務

6、進入Cassandra互動界面

cqlsh
           

[[email protected] ~]# cqlsh
Connected to Test Cluster at 127.0.0.1:9042.
[cqlsh 5.0.1 | Cassandra 3.11.6 | CQL spec 3.4.4 | Native protocol v4]
Use HELP for help.
cqlsh> 
           

坑點：

1、系統中需安裝Python2.7，下載下傳、安裝并啟動Cassandra才會正常，否則可能會遇到問題。

如安裝不了、登入失敗等等

# 登入失敗
[[email protected] ~]# cqlsh
Connection error: ('Unable to connect to any servers', {'127.0.0.1': error(111, "Tried connecting to [('127.0.0.1', 9042)]. Last error: Connection refused")})
