一.服务端的安装
所需的安装包：http://pan.baidu.com/s/1dFKaM8D
环境:centos7 IP:192.168.217.131
(1) step 1:install gcc and lamp env etc
yum install gccglibc glibc-common -y
yum install gdgd-devel -y
yum installhttpd php php-gd -y
yum installmysql* -y
(2) step 2:add nagios user and group
/usr/sbin/useradd-m nagios
#/usr/sbin/useraddapache
/usr/sbin/groupaddnagcmd
/usr/sbin/usermod-a -G nagcmd nagios
/usr/sbin/usermod-a -G nagcmd apache
(3) step 3:download and install nagios
unzipoldboy_training_nagios_soft.zip
tar xzfnagios-3.5.1.tar.gz
cd nagios
./configure 【--with-group=nagios --with-user=nagios
】--with-command-group=nagcmd
make all
make install
makeinstall-init
makeinstall-config
makeinstall-commandmode
makeinstall-webconf #出现404,说明没执行这个
(4) step 4:config web auth
htpasswd -cb/usr/local/nagios/etc/htpasswd.users tong 123456 //用户认证,登录nagios
(5) step 5:install nagios-plugins
yum -y installperl-devel
tar zxfnagios-plugins-2.1.1.tar.gz
cdnagios-plugins-2.1.1
./configure--with-nagios-user=nagios --with-nagios-group=nagios --
enable-perl-modules
make &&make install
ls /usr/local/nagios/libexec/|wc-l 看有几个
(6) step 6:install nrpe
tar zxvfnrpe-2.12.tar.gz
cd nrpe-2.12
./configure
make all
makeinstall-plugin
makeinstall-daemon
makeinstall-daemon-config
(7) step 7:startup service and check
/etc/init.d/nagios start
service httpd start
echo -----------
lsof -i tcp:80
echo ----------
ps -ef|grepnagios 没进程就iptables -F
echo"NAGIOS is successfully installed."
echo ok

二.客户端的安装
环境:centos7 IP:192.168.217.137
(1) step 1: add nagios user
#useradd -mnagios -s /sbin/nologin
(2) step 2: install nagios-plugins
yum -y install perl-devel
tar zxfnagios-plugins-2.1.1.tar.gz
cdnagios-plugins-2.1.1
./configure--prefix=/usr/local/nagios --enable-perl-modules --enable-redhat-pthread-workaround
make &&make install
ls/usr/local/nagios/libexec/|wc -l
(3) step 3: install nrpe
tar zxfnrpe-2.12.tar.gz
cd nrpe-2.12
./configure
make all
makeinstall-plugin
makeinstall-daemon
makeinstall-daemon-config
(4) step 4: install soft for iostat
tar zxvfParams-Validate-0.91.tar.gz
cdParams-Validate-0.91

#______________________
#for monitoriostat
yum installsysstat -y
【check_memory.pl安装包有】
/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
yum install -ydos2unix
dos2unix/usr/local/nagios/libexec/check_memory.pl
dos2unix/usr/local/nagios/libexec/check_iostat
ls/usr/local/nagios/libexec/|wc -l 插件数量
(5) step 5: 修改nrpe.cfg
cd/usr/local/nagios/etc/ #配置文件路径
#cp nrpe.cfgnrpe.cfg.bk 备份
#vim nrpe.cfg+79
perl -pi -e 's/allowed_hosts=127.0.0.1/
【allowed_hosts=127.0.0.1,192.168.217.131(服务端)】/g'
#delete 199--203【删掉的行】
cp/usr/local/nagios/etc/nrpe.cfg /usr/local/nagios/etc/nrpe.cfg.ori #复制
sed -i'199,203d' /usr/local/nagios/etc/nrpe.cfg
echo"command[check_load]=/usr/local/nagios/libexec/check_load -w 15,10,6
-c30,25,20">>/usr/local/nagios/etc/nrpe.cfg
echo"command[check_mem]=/usr/local/nagios/libexec/check_memory.pl -w 6%
-c3%">>/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
-c10">>/usr/local/nagios/etc/nrpe.cfg
(6) step 6: start nagios client
#start nagiosclient
pkill nrpe
sleep 2
#/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d #启动
#echo"/usr/local/nagios/bin/nrpe -c- /usr/local/nagios/etc/nrpe.cfg -
d">>/etc/rc.local 开机自动启动
#netstat-lnt|grep 5666 && echo "nagios client is ok"
三.登录验证：
由于没有启动客户端的机器，所以只能看到服务器的机器up
