第一步：修改YUM源碼
cd /etc/yum.repos.d/
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo
第二步：調(diào)整字符集
echo 'export LC_ALL=C'>> /etc/profile
source /etc/profile
echo $LC_ALL
第三部：關(guān)閉防火墻
/etc/init.d/iptables stop
/etc/init.d/iptables stop
chkconfig iptables off
setenforce 0 #臨時(shí)生效
sed -i 's#SELINUX=enforcing#SELINUX=disabled#g' /etc/selinux/config #永久生效
setenforce 0
sed -i 's#SELINUX=enforcing#SELINUX=disabled#g' /etc/selinux/config
第四部：時(shí)間同步
/usr/sbin/ntpdate pool.ntp.org
echo '#time sync'>>/var/spool/cron/root
echo '*/10 * * * * /usr/sbin/ntpdate pool.ntp.org >/dev/null 2>&1'>>/var/spool/cron/root
crontab -l
第五步:創(chuàng)建nagios用戶
/usr/sbin/useradd -m nagios -s /sbin/nologin

配置nrpe 配置文件
perl -pi -e 's/allowed_hosts=127.0.0.1/allowed_hosts=127.0.0.1,10.0.0.3/g' /usr/local/nagios/etc/nrpe.cfg
或者 sed -i 's/allowed_hosts=127.0.0.1/allowed_hosts=127.0.0.1,10.0.0.3/g' /usr/local/nagios/etc/nrpe.cfg
這一步的目的是，讓nagios服務(wù)端能夠到這來獲取設(shè)計(jì)
#delete 199--203
cp /usr/local/nagios/etc/nrpe.cfg /usr/local/nagios/etc/nrpe.cfg.ori
sed -i '199,203d' /usr/local/nagios/etc/nrpe.cfg

echo "command[check_iostat]=/usr/local/nagios/libexec/check_iostat -w 6 -c 10">>/usr/local/nagios/etc/nrpe.cfg
啟動(dòng)nagios 客戶端 nrpe
pkill nrpe
sleep 2
/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d
echo "#nagios nrpe process cmd by lvnian 2012-6-7" >> /etc/rc.local
echo "/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d">>/etc/rc.local
netstat -lnt|grep 5666
重啟nagios nrpe的命令：
pkill nrpe && /usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d ||/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d
netstat -lnt | grep 5666
檢查插件數(shù)量
[root@Nagios etc]# ls /usr/local/nagios/libexec/|wc -l

[root@centos tools]# ls /usr/local/nagios/libexec/|wc -l
