LR监控linux之详解rstatd的安装-Zee1. 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：rootlocalhost rpc.rstatd# lsaclocal.m4 COPYING Makefile.am README rstat_proc.crup.1config.h.in CVS Makefile.in rpc.rstatd.8rstat.x rup.cconfigure INSTALL missing rstatd.8 rsysinfo.1 stamp-h.inconfigure.ininstall-shmkinstalldirsrstat_main.crsysinfo.c2. 执行如下步骤：2.1.执行：./configure 命令rootlocalhost rpc.rstatd# ./configurecreating cache ./config.cachechecking for a BSD compatible install. /usr/bin/install -cchecking whether build environment is sane. yeschecking whether make sets $MAKE. yeschecking for working aclocal. foundchecking for working autoconf. foundchecking for working automake. foundchecking for working autoheader. foundchecking for working makeinfo. foundchecking for gawk. gawkchecking for gcc. gccchecking whether the C compiler (gcc) works. yeschecking whether the C compiler (gcc) is a cross-compiler. nochecking whether we are using GNU C. yeschecking whether gcc accepts -g. yeschecking for a BSD compatible install. /usr/bin/install -cchecking whether ln -s works. yeschecking whether make sets $MAKE.

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).
