1、添加nagios用户
echo "------ step 1: add nagios user------"
#create user group
/usr/sbin/useradd -m nagios -s /sbin/nologin


2、解压nagios软件包
echo "------ step 2: unzip nagios soft------"
mkdir -p /home/oldboy/tools/
cd /home/oldboy/tools/
[  ! -f ./oldboy_training_nagios_soft.zip ] &&{
echo "nagios soft is not exist."
exit 1
}
/bin/cp oldboy_training_nagios_soft.zip /home/oldboy/tools/
cd /home/oldboy/tools/


3、安装nagios插件
echo "------ step 3: install nagios-plugins------"
yum -y install perl-devel
tar zxf nagios-plugins-1.4.16.tar.gz
cd nagios-plugins-1.4.16
./configure --prefix=/usr/local/nagios --enable-perl-modules --enable-redhat-pthread-workaround 
make && make install
cd ../
ls /usr/local/nagios/libexec/|wc -l


echo "------ step 4: install nrpe------"
cd /home/oldboy/tools/
tar zxf nrpe-2.12.tar.gz
cd nrpe-2.12
./configure
make all
make install-plugin
make install-daemon
make install-daemon-config
cd ..


4、安装iostat监控相关插件
echo "------ step 4: install soft for iostat------"
cd /home/oldboy/tools/
tar zxvf Params-Validate-0.91.tar.gz 
cd Params-Validate-0.91 
perl Makefile.PL 
make
make install


#---------------------------------------- 
cd /home/oldboy/tools/
tar zxvf Class-Accessor-0.31.tar.gz
cd Class-Accessor-0.31
perl Makefile.PL
make
make install


#---------------------------------------- 
cd /home/oldboy/tools/
tar zxvf Config-Tiny-2.12.tar.gz
cd Config-Tiny-2.12
perl Makefile.PL
make
make install


#---------------------------------------- 
cd /home/oldboy/tools/
tar zxvf Math-Calc-Units-1.07.tar.gz
cd Math-Calc-Units-1.07
perl Makefile.PL
make
make install


#---------------------------------------- 
cd /home/oldboy/tools/
tar zxvf Regexp-Common-2010010201.tar.gz
cd Regexp-Common-2010010201
perl Makefile.PL
make
make install


#---------------------------------------- 
cd /home/oldboy/tools/
tar zxvf Nagios-Plugin-0.34.tar.gz
cd Nagios-Plugin-0.34
perl Makefile.PL
make
make install


#______________________ 


#for monitor iostat 
yum install sysstat -y


/bin/cp /home/oldboy/tools/check_memory.pl /usr/local/nagios/libexec
/bin/cp /home/oldboy/tools/check_iostat /usr/local/nagios/libexec


chmod 755 /usr/local/nagios/libexec/check_memory.pl
chmod 755 /usr/local/nagios/libexec/check_iostat


dos2unix /usr/local/nagios/libexec/check_memory.pl
dos2unix /usr/local/nagios/libexec/check_iostat


5、修改nrpe.cfg文件，添加服务端
echo "------ step 5: 修改nrpe.cfg------"
perl -pi -e 's/allowed_hosts=127.0.0.1/allowed_hosts=127.0.0.1,192.168.8.42/g' /usr/local/nagios/etc/nrpe.cfg 


#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


6、启动nagios客户端
echo "------ step 6: start nagios client------"
#start nagios client
pkill nrpe 
sleep 2
/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d
echo  "#nagios nrpe process cmd by jack 2016-07-21" >> /etc/rc.local
echo "/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d">>/etc/rc.local

netstat -lnt|grep 5666 && echo "nagios client is ok"


自动化安装脚本：

将oldboy_training_nagios_soft.zip压缩包拷贝到系统中
