在Mac上本地搭建Cassandra
概要:
Cassandra在本地的配置备忘录。我想在本地运行Cassandra,所以记录下必要的步骤。
步骤
准备Cassandra实体
这次尝试在Docker上运行
version: '2'
services:
cassandra:
image: cassandra:3.9
container_name: cassandra
ports:
- "9042:9042"
environment:
- "MAX_HEAP_SIZE=256M"
- "HEAP_NEWSIZE=128M"
restart: always
volumes:
- ./out/cassandra_data:/var/lib/cassandra0
※ 具體的設定可隨時更改
安装CQL(Cassandra版SQL)。
安装 pip
如果已安装则跳过 OK
$ sudo easy_install pip
2. 使用pip安装CQL
$ sudo pip install cql
在我的环境中,出现了以下错误。
ERROR: Cannot uninstall 'six'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.
加入选项后可以避免这个问题。
$ sudo pip install cql -I six
※ pip 选项清单
3. 连接至Cassandra
开启Docker后进行连接。
$ cqlsh
Connected to Test Cluster at 127.0.0.1:9042.
[cqlsh 5.0.1 | Cassandra 3.9 | CQL spec 3.4.2 | Native protocol v4]
