上一篇我们完成了任务调度的持久化，传送门：任务调度之持久化（基于Quartz.net）
这篇我们来完成Quartz.net的一个比较优秀的功能，即集群；集群可以提高任务调度服务的容灾性，
当一个节点宕机后，其他节点会自动补上去，把超时的Job继续执行下去。
当然了，某个Job同一时刻只会运行在一个节点上，他们是通过数据库锁实现的。
1、集群依赖于数据表
之前2张我们介绍的都是运行在内存上的Job，而集群则一定需要依赖于Quartz.net本身的数据表结构才行

直接创建数据库运行就好了，至于表结构用途请百度
2、修改JobServer
RemoteServer.cs，即上篇的那个服务端的类
properties["quartz.jobStore.clustered"] = "true";
properties["quartz.jobStore.type"] = "Quartz.Impl.AdoJobStore.JobStoreTX, Quartz";
properties["quartz.jobStore.tablePrefix"] = "QRTZ_";
properties["quartz.jobStore.driverDelegateType"] = "Quartz.Impl.AdoJobStore.SqlServerDelegate, Quartz";
properties["quartz.jobStore.dataSource"] = "myDS";
properties["quartz.dataSource.myDS.connectionString"] = @"Data Source=JIANRONGLAN-PC\SQLEXPRESS;Initial Catalog=SystemBase;User ID=sa;Password=123456";
properties["quartz.dataSource.myDS.provider"] = "SqlServer-20";
参数初始化中加上上边的参数就可以了，其他不用改
3、远端控制界面
MVC的控制界面有改动，上一篇我们是新建了一个Job表，包含很多字段，但是现在加入组件本身的表结构，那Job有些字段就点多余；
所以我把时间和状态字段删掉了，新Job
public class Job
{
[IgnoreProperty(true)]
public int RowNumber { get; set; } /// <summary>Id</summary>
public Guid Id { get; set; } /// <summary>GroupName</summary>
public string GroupName { get; set; } /// <summary>JobName</summary>
public string JobName { get; set; } /// <summary>TriggerName</summary>
public string TriggerName { get; set; } /// <summary>Cron</summary>
public string Cron { get; set; } /// <summary>Description</summary>
public string Description { get; set; } /// <summary>CreateTime</summary>
public DateTime CreateTime { get; set; }
}
然后列表查询的时候直接关联QRTZ_TRIGGERS 就好了，我们来看看效果
4、部署Quartz节点
4.1 拷贝JobServer，运行JobServer.exe，分别是128/129
好了，现在2个机器服务端都在等待状态了
4.2、控制端开启任务
4.3、看到分配到129运行了，最后执行时间是23：45:15，这是128还是等等状态的。然后关闭129的JobServer
4.4、128开始运行，看到128在23:46:42才开始运行
好了，集群就这么多点东西，很简单的，搭建环境还比较麻烦
