正常关闭服务
从 NetScaler 12.1 build 49.xx 开始,NetScaler 群集支持正常关闭服务。要正常关闭服务,可以执行以下任务之一。
-
明确禁用该服务,以及
- 设置延迟(以秒为单位)。
- 启用正常关闭。
-
向监视器添加 TROFS 代码或字符串。
有关更多详细信息,请参阅 优雅关闭服务。
使用 CLI 为服务配置正常关闭
仅使用优雅选项禁用:
在命令提示符下,键入:
disable service <name> [-graceFul (YES|NO)]
show service <name>
<!--NeedCopy-->
示例
disable service svc1 -graceFul YES
Done
sh service svc1
svc1 (10.102.225.11:80) - HTTP
State: GOING OUT OF SERVICE Graceful (number of active clients: 1)

使用超时和优雅选项禁用:
在命令提示符下,键入:
disable service <name> [<delay>] [-graceFul (YES|NO)]
show service <name>
<!--NeedCopy-->
示例
disable service svc1 2000 -graceFul YES
Done
> sh service svc1
svc1 (10.102.225.11:80) - HTTP
State: GOING OUT OF SERVICE (Graceful (number of active clients: 1), Out Of Service in 1998 seconds)

使用超时和优雅选项禁用服务组:
在命令提示符下,键入:
disable serviceGroup <serviceGroupName>@ [<serverName>@ <port>] [-delay
<secs>] [-graceFul ( YES | NO )]
Show service group <serviceGroupName>

示例:
disable servicegroup sg -delay 2000 -graceFul yes
sh servicegroup sg
