大家好，又见面了，我是全栈君。

LR监控linux之详解rstatd的安装-Zee

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_xdr.c

rpcgen -c -o rstat_xdr.c rstat.x

gcc -DHAVE_CONFIG_H -I. -I. -I. -g -O2 -c rstat_xdr.c

rm -f rstat_clnt.c

rpcgen -l -o rstat_clnt.c rstat.x

gcc -DHAVE_CONFIG_H -I. -I. -I. -g -O2 -c rstat_clnt.c

gcc -g -O2 -o rup rup.o rstat_xdr.o rstat_clnt.o

gcc -DHAVE_CONFIG_H -I. -I. -I. -g -O2 -c rsysinfo.c

rsysinfo.c: In function
‘

‘
?

rsysinfo.c:136: warning: passing argument 6 of

‘
?gcc -g -O2 -o rsysinfo rsysinfo.o rstat_xdr.o rstat_clnt.o

rm -f rstat_svc.c

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

gcc -DHAVE_CONFIG_H -I. -I. -I. -g -O2 -c rstat_main.c

rstat_main.c: In function
‘m

?

rstat_main.c:82: warning: return type of
‘m

‘
?is not
‘i
nt
‘
?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]

Monitor name :UNIX Resources. Internal rpc error (error code:2). Machine: 10.1.200.65. Hint: Check that RPC on this machine is up and running. Check that rstat daemon on this machine is up and running (use rpcinfo utility for this verification). Details: RPC: RPC call failed.

RPC-TCP: recv()/recvfrom() failed.

RPC-TCP: Timeout reached. (entry point: Factory::CollectData). [MsgId: MMSG-47197]

至此完毕。
