随着互联网技术的飞速发展，企业对服务器性能的要求越来越高，为了提高服务器的稳定性和可用性，许多企业选择采用服务器集群技术，本文将深入探讨两台服务器构建集群的详细步骤，并介绍集群信息整合的方法。

两台服务器构建集群的步骤

1、确定集群架构

在构建集群之前，首先需要确定集群的架构，常见的集群架构有主从架构、负载均衡架构和分布式存储架构等，根据企业需求选择合适的架构。

2、选择合适的集群软件

根据确定的集群架构，选择合适的集群软件，常见的集群软件有Keepalived、Heartbeat、LVS等，以下以Keepalived为例进行介绍。

3、安装Keepalived

在两台服务器上分别安装Keepalived，以下是CentOS系统下的安装步骤：

（1）安装EPEL源

[root@server1 ~]# yum install epel-release

（2）安装Keepalived

[root@server1 ~]# yum install keepalived

4、配置Keepalived

在两台服务器上分别编辑Keepalived的配置文件。

（1）编辑server1的配置文件：

[root@server1 ~]# vi /etc/keepalived/keepalived.conf

配置如下：

! Configuration File for keepalived

global_defs {

router_id LVS_DEVEL

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 {

delay_loop 6

lb_method RR

quiescent 60

unix_socket /var/run/keepalived/keepalived.sock

connect_timeout 10

nb_get_conn 0

health_check_interval 5

health_check_timeout 5

health_check_type HTTP

health_check_url /check.html

（2）编辑server2的配置文件：

[root@server2 ~]# vi /etc/keepalived/keepalived.conf

配置如下：

! Configuration File for keepalived

global_defs {

router_id LVS_DEVEL

vrrp_instance VI_1 {

state BACKUP

interface eth0

virtual_router_id 51

priority 90

advert_int 1

authentication {

auth_type PASS

auth_pass 123456

}

virtual_ipaddress {

192.168.1.100/24 dev eth0 label eth0:0

}

5、启动Keepalived

在两台服务器上分别启动Keepalived。

[root@server1 ~]# systemctl start keepalived

[root@server2 ~]# systemctl start keepalived

6、检查集群状态

使用命令查看集群状态。

[root@server1 ~]# vrrpctl show

Interface: eth0

VRRP Virtual Router ID : 51

Current local status is MASTER

Virtual IP Address: 192.168.1.100/24

Virtual Interface: eth0:0

...

[root@server2 ~]# vrrpctl show

Interface: eth0

VRRP Virtual Router ID : 51

Current local status is BACKUP

Virtual IP Address: 192.168.1.100/24

Virtual Interface: eth0:0

...

集群信息整合

1、集群监控

为了实时监控集群状态，可以使用Nagios、Zabbix等监控工具，以下以Nagios为例进行介绍。

（1）安装Nagios

[root@server1 ~]# yum install nagios nagios-plugins nagios-server nagios-plugins-all

（2）配置Nagios

编辑Nagios的配置文件，添加Keepalived监控项。

[root@server1 ~]# vi /etc/nagios/nagios.cfg

配置如下：

command_file /usr/local/nagios/var/rw/contactcommands.cfg

command_file /usr/local/nagios/var/rw/objectcommands.cfg

command_file /usr/local/nagios/var/rw/checkcommands.cfg

define command{

command_name check_keepalived

command_line /usr/local/nagios/bin/check_by_sh -H $HOSTADDRESS$ -C Keepalived -W "Check Keepalived Status"

define command{

command_name restart_keepalived

command_line /usr/local/nagios/bin/check_by_sh -H $HOSTADDRESS$ -C Keepalived -W "Restart Keepalived"

define contact{

contact_name root

contact_email root@localhost

define host{

host_name server1

alias server1

address 192.168.1.100

contact_groups admins

use generic-host

define service{

service_description Keepalived Status

contact_groups admins

use generic-service

check_command check_keepalived

notifications_enabled yes

event_handler restart_keepalived

（3）启动Nagios

[root@server1 ~]# systemctl start nagios

2、集群日志收集

使用rsyslog、syslog-ng等日志收集工具，将集群日志集中到一台服务器上进行存储和分析。

（1）安装rsyslog

[root@server1 ~]# yum install rsyslog

（2）配置rsyslog

编辑rsyslog的配置文件，添加集群日志收集规则。

[root@server1 ~]# vi /etc/rsyslog.conf

配置如下：

$ModLoad imtcp

$ModLoad imudp

$UDPServerRun 514

$SyslogFacilityLocal0 = LOG_LOCAL0

$SyslogFacilityLocal1 = LOG_LOCAL1

$SyslogFacilityLocal2 = LOG_LOCAL2

$SyslogFacilityLocal3 = LOG_LOCAL3

$SyslogFacilityLocal4 = LOG_LOCAL4

$SyslogFacilityLocal5 = LOG_LOCAL5

$SyslogFacilityLocal6 = LOG_LOCAL6

$SyslogFacilityLocal7 = LOG_LOCAL7

$SyslogFacilityLocal8 = LOG_LOCAL8

$SyslogFacilityLocal9 = LOG_LOCAL9

$SyslogFacilityLocal10 = LOG_LOCAL10

$SyslogFacilityLocal11 = LOG_LOCAL11

$SyslogFacilityLocal12 = LOG_LOCAL12

$SyslogFacilityLocal13 = LOG_LOCAL13

$SyslogFacilityLocal14 = LOG_LOCAL14

$SyslogFacilityLocal15 = LOG_LOCAL15

$IncludeConfig /etc/rsyslog.d/*.conf

*.* @192.168.1.100

（3）启动rsyslog

[root@server1 ~]# systemctl start rsyslog
