windows服务器热备、负载均衡配置-编程知识

安装网络负载平衡

需要加入的服务器上全部需要安装网络负载平衡管理器

图形化安装：使用服务器管理器安装

在服务器管理器中，使用“添加角色和功能”向导添加网络负载均衡功能。完成向导后，将安装 NLB，并且不需要重启计算机。

找到控制面板在控制面版中找到下图选项，点击启用或关闭windows功能

点击进入，找到下图中标记的位置，点击进入添加功能

在所有选择中找到下图的选项。点击下一步

确认选择的安装组件，然后点击安装。

等待安装完成

安装完成之后，关闭（安装成功后需重启计算机）。

命令行、脚本安装

安装方式1

REM 启用网络负载平衡管理器
dism.exe /online /enable-feature /featurename:NetworkLoadBalancingFullServer  /norestart
REM 禁用网络负载平衡管理器
dism.exe /online /disable-feature /featurename:NetworkLoadBalancingFullServer  /norestart

安装方式2

使用 Windows PowerShell 安装

若要使用 Windows PowerShell 安装 NLB，请在要安装 NLB 的计算机上，在提升的 Windows PowerShell 提示符处运行以下命令。

PowerShell复制

Install-WindowsFeature NLB -IncludeManagementTools

安装完成后，无需重启计算机。

配置网络负载平衡

图形化配置

在开始菜单中搜索网络负载平衡管理器，找到组件选项，打开。

下图是进入之后的页面，鼠标右键点击“网络负载平衡管理器”。

新建集群

填写好创建集群的电脑IP地址进行连接，之后下方选项栏里会出现本机服务器的网卡，选择要进行集群的网卡，然后点击下一步。

选择本机电脑所添加的优先级别（后续添加完成之后是可以修改的）选择之后，点击下一步

点击添加

图中IPv4地址,是这个集群的虚拟ip（VIP）设置好之后点击确定

确认添加成功之后点击下一步

根据实际情况选择单播，或者多播，选择完成之后点击下一步

单播和多播的区别：

VMware Knowledge Base

点击完成之后，集群就已经建立成功了。

在点击刚建立好的集群，可以看到状态，状态为“已启用”说明集群创建完成了

集群主机主动添加另一台主机进入集群

搜索需要进入这个集群的服务器IP，选择好网卡之后，点击下一步

点击链接的时候报错如下

选择优先级，点击下一步

点击完成，加入主机完成

待加入集群服务器搜索集群加入

在使用另一台需要进入集群的服务器搜索创建的集群IP，加入集群。

输入搜索要加入的集群IP，在下图群集中可以看到搜索到的集群，选择要加入的集群，点击完成进入集群

命令行、脚本配置
