1.前期准备：
1,把rstatd文件解压到要监控的机器上。
2,打开终端，定位到rstatd文件夹下：查看文件夹中的内容如下：
[root@localhost rpc.rstatd]# ls
aclocal.m4 COPYING Makefile.am README rstat_proc.c rup.1
config.h.in CVS Makefile.in rpc.rstatd.8 rstat.x rup.c
configure INSTALL missing rstatd.8 rsysinfo.1 stamp-h.in
configure.in install-sh mkinstalldirs rstat_main.c rsysinfo.c
2.执行如下步骤：
2.1.执行：./configure 命令
[root@localhost rpc.rstatd]# ./configure
creating cache ./config.cache
checking for a BSD compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking whether make sets ${MAKE}... yes
checking for working aclocal... found
checking for working autoconf... found
checking for working automake... found
checking for working autoheader... found
checking for working makeinfo... found
checking for gawk... gawk
checking for gcc... gcc
checking whether the C compiler (gcc ) works... yes
checking whether the C compiler (gcc ) is a cross-compiler... no
checking whether we are using GNU C... yes
checking whether gcc accepts -g... yes
checking for a BSD compatible install... /usr/bin/install -c
checking whether ln -s works... yes
checking whether make sets ${MAKE}... (cached) yes
checking how to run the C preprocessor... gcc -E
checking for sys/ioctl.h... yes
checking for syslog.h... yes
checking whether time.h and sys/time.h may both be included... yes
checking whether gcc needs -traditional... no
checking for ANSI C header files... yes
checking return type of signal handlers... void
updating cache ./config.cache
creating ./config.status
kcreating Makefile
creating config.h
2.2.执行：make 命令。
[root@localhost rpc.rstatd]# make
rm -f rstat.h
rpcgen -h -o rstat.h rstat.x
gcc -DHAVE_CONFIG_H -I. -I. -I. -g -O2 -c rup.c

rm -f rstat_clnt.c
rpcgen -l -o rstat_clnt.c rstat.x

rpcgen -m -o rstat_svc.c rstat.x
gcc -DHAVE_CONFIG_H -I. -I. -I. -g -O2 -c rstat_svc.c
gcc -DHAVE_CONFIG_H -I. -I. -I. -g -O2 -c rstat_proc.c

rstat_main.c:82: warning: return type of 'main'?is not 'int'?gcc -g -O2 -o rpc.rstatd rstat_svc.o rstat_xdr.o rstat_proc.o rstat_main.o
这之后可以执行:make check检查一下。
2.3.执行：make install 命令。
[root@localhost rpc.rstatd]# make install
make[1]: Entering directory `/opt/rpc.rstatd'
/bin/sh ./mkinstalldirs /usr/local/bin
/usr/bin/install -c rup /usr/local/bin/rup
/usr/bin/install -c rsysinfo /usr/local/bin/rsysinfo
/bin/sh ./mkinstalldirs /usr/local/sbin
/usr/bin/install -c rpc.rstatd /usr/local/sbin/rpc.rstatd
make[1]: Nothing to be done for `install-data-am'.
make[1]: Leaving directory `/opt/rpc.rstatd'
2.4.执行：./rpc.rstatd 命令。启动rpc服务。
注：无回显为成功。
[root@localhost rpc.rstatd]# ./rpc.rstatd
2.5.执行：rpcinfo –p 命令。检查rpc服务的状态.
[root@localhost rpc.rstatd]# rpcinfo -p
program vers proto port
100000 2 tcp 111 portmapper
100000 2 udp 111 portmapper
100024 1 udp 797 status
100024 1 tcp 800 status
100001 5 udp 900 rstatd
100001 3 udp 900 rstatd
100001 2 udp 900 rstatd
100001 1 udp 900 rstatd
[root@localhost rpc.rstatd]#
3. 可能会出现的错误：
1,若RPC服务没有成功启动。
2,若目标主机上开启了防火墙，阻挡了RPC服务。
在LR中添加时可能会出现如下错误：
Monitor name :UNIX Resources. Cannot initialize the monitoring on 10.1.200.65. 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.
RPC-TCP: Failed to establish RPC server address.
RPC-TCP: RPC Server <100001, 3, 17> is not registered on host '10.1.200.65'. (entry point: CFactory::Initialize). [MsgId: MMSG-47190]
