我正在尝试在使用GFSH命令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
缓存. 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,我得到了以下异常。

有什么帮助吗?
我使用netstat查找端口是否被占用。我找不到任何,我执行了脚本,但我仍然得到相同的异常。
bash-4.1$ netstat | grep 40405
bash-4.1$ ./startServer.sh

这意味着在localhost上运行的一些其他进程已经绑定并侦听端口40405上的客户端套接字连接。也许您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尽可能多的服务器的端口号,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进程已经在使用该端口号运行,请考虑终止该进程或为您的GemFireCacheServers
使用另一个端口。
您可以使用Linuxnetstat
命令来查找哪个进程正在使用端口并采取适当的行动。
