Cassandra搭建步骤

在当今大数据时代，分布式数据库的应用越来越广泛，Cassandra作为一种高性能、可扩展的分布式数据库，因其优秀的读写性能、高可用性和灵活性，受到了众多开发者的青睐，本文将详细介绍如何在VPS环境下搭建Cassandra数据库。

Cassandra简介

Cassandra是由Facebook开发的一款分布式NoSQL数据库，它采用分布式架构，支持海量数据存储，具有高可用性、高可靠性、易于扩展等特点，Cassandra适用于处理大规模数据集，特别是在需要高并发读写、高可用性和高可靠性的场景下。

VPS环境准备

1、选择合适的VPS提供商：选择具有良好性能、稳定性和可靠性的VPS提供商，如阿里云、腾讯云、华为云等。

2、系统要求：Cassandra支持多种操作系统，如Linux、Windows、macOS等，本文以CentOS 7为例进行讲解。

3、网络要求：确保VPS服务器具备公网IP，以便后续进行远程访问。

4、Java环境：Cassandra使用Java编写，需要安装Java环境，推荐使用OpenJDK。

Cassandra搭建步骤

1、安装Java环境

更新系统软件包：

sudo yum update

安装OpenJDK：

sudo yum install java-1.8.0-openjdk

验证Java版本：

java -version

2、下载Cassandra安装包

从Cassandra官网（https://cassandra.apache.org/download/）下载最新版本的安装包，本文以Cassandra 3.11.6为例。

wget https://archive.apache.org/dist/cassandra/3.11.6/apache-cassandra-3.11.6-bin.tar.gz

3、解压安装包

将下载的安装包解压到指定目录：

tar -zxvf apache-cassandra-3.11.6-bin.tar.gz -C /usr/local/

4、配置Cassandra

进入Cassandra解压后的目录：

cd /usr/local/apache-cassandra-3.11.6

修改配置文件conf/cassandra.yaml：

The name of the cluster. This is mainly used to prevent machines in
one cluster from joining another.
cluster_name: 'Test Cluster'
The seed provider is responsible for providing a list of addresses
for the initial contact points of the cluster. This should include
at least one address from every data center. The seed provider
should also contain the addresses of all nodes in the cluster,
but it can be configured to exclude certain nodes by IP address
or rack.
seed_provider:
    # Addresses of contact points for the initial connection to the cluster.
    # The node will attempt to connect to these contact points to
    # discover the cluster. If the provided contact points are not
    # reachable, the node will attempt to connect to the broadcast
    # address (169.254.100.100) to find nodes in the local data center.
    - class_name: "org.apache.cassandra.locator.SimpleSeedProvider"
      parameters:
        # List of addresses (hostnames or IP addresses) to use as contact points
        # for initial connections to the cluster.  At least one address must
        # be specified, and it can contain multiple addresses, separated by
        # spaces.
        - seeds: "127.0.0.1"
The endpoint snitch is responsible for determining the location of nodes
within the cluster.  This information is used to determine which nodes
are responsible for a given piece of data.
endpoint_snitch: SimpleSnitch
Initial token for the new node.  If left empty, Cassandra will choose
a token for the new node.  This is only used for new nodes, and existing
nodes will throw an error if this is set.
initial_token:
Partitioner to use for the cluster.  Cassandra supports several partitioners,
each with their own trade-offs.
partitioner: org.apache.cassandra.dht.Murmur3Partitioner
The number of milliseconds the node should wait for a response when
sending a message to another node. This is used for various timeouts,
such as timeouts for read and write requests, and timeouts for
inter-node communication.
read_request_timeout_in_ms: 5000
write_request_timeout_in_ms: 20000
Timeout for a hints delivery attempt. If hints cannot be delivered
within this time frame, the delivery attempt will be abandoned.
hints_timeout_in_ms: 10000
Timeout for a request to a coordinator node. If a coordinator does not
respond within this time frame, the request will be failed.
request_timeout_in_ms: 10000
Timeout for a read repair request. If a read repair cannot be completed
within this time frame, the repair will be abandoned.
read_repair_timeout_in_ms: 20000
Timeout for a broadcast message. If a broadcast message cannot be
delivered within this time frame, the message will be dropped.
broadcast_timeout_in_ms: 10000
Timeout for a large message (i.e., a message larger than the
streaming threshold). If a large message cannot be delivered within
this time frame, the message will be dropped.
streaming_timeout_in_ms: 40000
Timeout for a truncation request. If a truncation request cannot be
completed within this time frame, the request will be failed.
truncation_timeout_in_ms: 60000
Timeout for a compaction request. If a compaction request cannot be
completed within this time frame, the request will be failed.
compaction_timeout_in_ms: 120000
Timeout for a cleanup request. If a cleanup request cannot be
completed within this time frame, the request will be failed.
cleanup_timeout_in_ms: 120000
Timeout for a repair request. If a repair request cannot be
completed within this time frame, the request will be failed.
repair_timeout_in_ms: 360000
Timeout for a snapshot request. If a snapshot request cannot be
completed within this time frame, the request will be failed.
snapshot_timeout_in_ms: 60000
Timeout for a restore request. If a restore request cannot be
completed within this time frame, the request will be failed.
restore_timeout_in_ms: 120000

The number of milliseconds to wait for the peer to respond to a
stage management request. This is used for various stage management
timeouts, such as timeouts for stage initialization and cleanup.
stage_timeout_in_ms: 10000
The number of milliseconds to wait for a node to become unreachable
before considering it down. This is used to determine when to begin
the process of replacing a node that is suspected to be down.
unreachable_timeout_in_ms: 8000
The number of milliseconds to wait for a node to be considered down
after it has been unreachable for the specified unreachable_timeout.
This is used to determine when to begin the process of replacing a
node that is confirmed to be down.
shutdown_timeout_in_ms: 15000
The number of milliseconds to wait for a node to be considered down
after it has been unreachable for the specified unreachable_timeout,
but before it is removed from the cluster. This is used to give the
node a chance to recover and rejoin the cluster before it is removed.
