我需要configurationSymmtricDS在Linux的红帽机器作为Master.I指的是URLconfiguration在Linux中我安装了symmtricDS，但是当我启动服务，使用下面的命令
[root@samrtcity bin]# sudo sh sym_service start 它会显示这样的错误
Waiting for server to start .. java -Djava.io.tmpdir=/opt/SymmtricDS/symmetric-server-3.7.28/symmetric-server-3.7.28/tmp -jar /opt/SymmtricDS/symmetric-server-3.7.28/symmetric-server-3.7.28/lib/symmetric-wrapper.jar exec /opt/SymmtricDS/symmetric-server-3.7.28/symmetric-server-3.7.28/conf/sym_service.conf Error: Exception thrown by the agent : java.net.MalformedURLException: Local host name unknown: java.net.UnknownHostException: samrtcity.in: samrtcity.in: unknown error java.lang.IllegalThreadStateException: process hasn't exited at java.lang.UNIXProcess.exitValue(UNIXProcess.java:424) at org.jumpmind.symmetric.wrapper.WrapperService.execJava(WrapperService.java:201) at org.jumpmind.symmetric.wrapper.WrapperHelper.run(WrapperHelper.java:32) at org.jumpmind.symmetric.wrapper.Wrapper.main(Wrapper.java:48) Error 8: Failed second stage Native error 8
