安裝nagios 用戶端

用戶端僅僅需要安裝下面內容

Class-Accessor-0.31.tar.gz

Config-Tiny-2.12.tar.gz

Math-Calc-Units-1.07.tar.gz

Nagios-Plugin-0.34.tar.gz

Params-Validate-0.91.tar.gz

Regexp-Common-2010010201.tar.gz

check_iostat

check_memory.pl

nrpe-2.12.tar.gz

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：調整字元集

echo ‘export LC_ALL=C‘>> /etc/profile

source /etc/profile

echo $LC_ALL

第三部：關閉防火牆

/etc/init.d/iptables stop

/etc/init.d/iptables stop

chkconfig iptables off

setenforce 0         #臨時生效

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:建立nagios使用者

/usr/sbin/useradd -m nagios -s /sbin/nologin

第六步：安裝nagios用戶端外掛程式

配置nrpe 設定檔

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服務端能夠到這來擷取設計

#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_load]=/usr/local/nagios/libexec/check_load -w 15,10,6 -c 30,25,20">>/usr/local/nagios/etc/nrpe.cfg

echo "command[check_mem]=/usr/local/nagios/libexec/check_memory.pl -w 6% -c 3%">>/usr/local/nagios/etc/nrpe.cfg

echo "command[check_disk]=/usr/local/nagios/libexec/check_disk -w 20% -c 8% -p /">>/usr/local/nagios/etc/nrpe.cfg

echo "command[check_swap]=/usr/local/nagios/libexec/check_swap -w 20% -c 10%">>/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nagios 用戶端 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

檢查外掛程式數量

[[email protected] etc]# ls /usr/local/nagios/libexec/|wc -l

[[email protected] tools]# ls /usr/local/nagios/libexec/|wc -l
