lr监控linux系统应用经常会出现"Monitor name :UNIX Resources. Cannot initialize the monitoring on 192.168.52.189. Error while creating the RPC client. Ensure that the machine can be connected and that it runs the rstat daemon (use rpcinfo utility for this verification). Detailed error: RPC: Failed to create RPC client."

意思是没有安装或者没有启动rpc.start服务。

然后就区服务器上查看下有没有安装。没有安装的发就下载安装

安装rstatd
下载地址：http://sourceforge.net/projects/rstatd，上传至/usr/local
查看是否安装rstatd
[root@localhost /]# find / -name rpc.rstatd

安装rstatd
[root@localhost /]# tar -xzvf rpc.rstatd-4.0.1.tar.gz
[root@localhost /]# cd rpc.rstatd-4.0.1
[root@localhost /]# ./configure
[root@localhost /]# make
[root@localhost /]# make install

安装后启动

然后翻阅了很多资料

----------------------------------------------------------------------------------------

这个错误是因为服务器没有开启端口映射的功能，需要安装portmap。

解决办法：

[root@rhel64-a RedHat60AS_26x86_64]# yum install portmap

[root@rhel64-b ~]# /etc/init.d/cvfs fullstop

启动portmap服务故障解决

[root@rhel64-b RedHat60AS_26x86_64]# /etc/init.d/rpcbind start

然后再启动：rpc.start服务就成
