Question

我正在尝试使用GFSH命令在启动缓存服务器时创建GemFire缓存和区域。

GFSH：

gfsh start server --name=server1 --server-port=40405 --classpath=$CLASSPATH   --cache-xml=/tmp/gemfire/8.2.7/config/cache.xml  --locators=hostA[10334],hostB[10334] --mcast-port=0

Cache.xml：

<?xml version="1.0" encoding="UTF-8"?><cache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schema.pivotal.io/gemfire/cache" xsi:schemaLocation="http://schema.pivotal.io/gemfire/cache http://schema.pivotal.io/gemfire/cache/cache-8.1.xsd" version="8.1" lock-lease="120" lock-timeout="60" search-timeout="300" is-server="false" copy-on-read="false">
 <pdx>
    <pdx-serializer>
      <class-name>
       com.gemstone.gemfire.pdx.ReflectionBasedAutoSerializer
      </class-name>
    <parameter name="classes">
      <string>com.gemfire.DomainObjects</string>
    </parameter>
  </pdx-serializer>
 </pdx>
<region name="Customer" refid="REPLICATE"></region>
</cache>

当我运行gfsh命令时，我遇到异常。

任何帮助？

我使用netstat查找端口是否被占用。我找不到任何和我执行脚本仍然得到同样的例外。

bash-4.1$ netstat | grep 40405
bash-4.1$ ./startServer.sh

这意味着在localhost上运行的其他进程已经绑定并侦听端口 40405 上的客户端套接字连接。也许你已经在该端口上运行了另一个GemFire服务器？

在这种情况下，您需要在启动时更改任意数量的服务器的端口号，例如......

gfsh> start server --name=One --server-port=40405 ...
...
gfsh> start server --name=Two --server-port=40406 ...
...
gfsh> start server --name=Three --server-port=40407 ...
...

......等等。

如果非GemFire进程已使用该端口号运行，而不是考虑终止该进程或使用GemFire CacheServers的其他端口。

您可以使用Linux netstat命令查找正在使用该端口的进程并采取相应的操作。

使用GFSH的GemFire - 使用服务器启动创建区域会抛出BindException
