随着互联网技术的飞速发展，服务器集群在提高系统性能、保证系统稳定性和扩展性等方面发挥着越来越重要的作用，本文将详细介绍如何搭建两台服务器集群，从基础环境搭建到实践操作，旨在帮助读者全面了解服务器集群的搭建过程。

搭建两台服务器集群的准备工作

1、硬件环境

（1）两台服务器：选择性能稳定、配置较高的服务器，如Intel Xeon系列处理器、至少16GB内存、1TB硬盘等。

（2）网络设备：至少两块网络接口卡，用于搭建集群内通信和对外提供服务。

2、软件环境

（1）操作系统：Linux操作系统，如CentOS、Ubuntu等。

（2）集群管理软件：如Heartbeat、Keepalived、Corosync等。

（3）数据库软件：如MySQL、MongoDB等。

（4）应用程序：根据业务需求选择合适的应用程序。

搭建两台服务器集群的步骤

1、配置网络

（1）配置服务器IP地址：确保两台服务器IP地址在同一网段，如192.168.1.1和192.168.1.2。

（2）配置网络接口：确保两块网络接口卡分别连接到不同的交换机或路由器，以便实现集群内通信和对外提供服务。

2、安装操作系统

（1）选择合适的Linux发行版，如CentOS。

（2）下载并安装操作系统。

（3）配置系统参数，如设置时区、主机名、网络等。

3、安装集群管理软件

（1）Heartbeat：是一款基于Linux的集群管理软件，可以实现高可用性和负载均衡等功能。

（2）Keepalived：是一款开源的虚拟IP（VIP）管理软件，可以实现高可用性和负载均衡等功能。

（3）Corosync：是一款基于Linux的集群管理软件，可以实现高可用性和负载均衡等功能。

4、配置集群管理软件

（1）Heartbeat配置：

①安装Heartbeat：

yum install heartbeat

②配置Heartbeat：

vi /etc/heartbeat/ha.cf

logfile /var/log/ha-log/ha.log
logfile_prefix ha_
load_policy 20
sticky_keys daemons
auto_failback yes

vi /etc/heartbeat/haresources

group test
    192.168.1.1
    192.168.1.2

③启动Heartbeat：

service heartbeat start

（2）Keepalived配置：

①安装Keepalived：

yum install keepalived

②配置Keepalived：

vi /etc/keepalived/keepalived.conf

! Configuration File for keepalived
global_defs {
    router_id 192.168.1.1
}
vrrp_instance VI_1 {
    state MASTER
    interface eth0
    virtual_router_id 51
    priority 100
    advert_int 1
    authentication {
        auth_type PASS
        auth_pass 123456
    }
    virtual_ipaddress {
        192.168.1.100/24 dev eth0 label eth0:0
    }
}
virtual_server 192.168.1.100 80 {
    list_of_targets {
        192.168.1.1:80
        192.168.1.2:80
    }
}

③启动Keepalived：

service keepalived start

（3）Corosync配置：

①安装Corosync：

yum install corosync

②配置Corosync：

vi /etc/corosync/corosync.conf
