tar zxf nagios-plugins-1.4.16.tar.gz
cd nagios-plugins-1.4.16
./configure --with-nagios-user=nagios --with-nagios-group=nagios --with-openssl=/usr/bin/openssl --enable-perl-modules
make
make install
cd ../
3)、安装nrpe
scp root@172.26.159.180:/root/xzy/nrpe-2.13.tar.gz /usr/local/src/nrpe-2.13.tar.gz
tar zxf nrpe-2.13.tar.gz
cd nrpe-2.13
./configure --with-nrpe-user=nagios --with-nrpe-group=nagios --with-nagios-user=nagios --with-nagios-group=nagios --enable-command-args --enable-ssl
make all
make install-plugin
make install-daemon
make install-daemon-config
cd ../
验证NRPE安装
/usr/local/nagios/libexec/check_load -w 15,10,5 -c 30,25,20
4)、安装ndoutils
scp root@172.26.159.180:/root/xzy/ndoutils-1.5.2.tar.gz /usr/local/src/ndoutils-1.5.2.tar.gz
tar zxf ndoutils-1.5.2.tar.gz
cd ndoutils-1.5.2
./configure --prefix=/usr/local/nagios/ --enable-mysql --with-ndo2db-user=nagios --with-ndo2db-group=nagios
make
make install
cp ./config/ndo2db.cfg-sample /usr/local/nagios/etc/ndo2db.cfg
cp ./config/ndomod.cfg-sample /usr/local/nagios/etc/ndomod.cfg
cp daemon-init /etc/init.d/ndo2db
vi /etc/init.d/ndo2db
killproc_ndo2db ()
{
##重复两行
kill `pidof ndo2db |cut -f1 -d " "` >/dev/null 2>&1
kill `pidof ndo2db |cut -f1 -d " "` >/dev/null 2>&1
}
stop)
echo "Stopping $servicename..."
killproc_ndo2db
保存文件后，继续执行命令
chmod +x /etc/init.d/ndo2db
chkconfig --add ndo2db
chkconfig --level 345 ndo2db on
cd ../
5)、安装centreon
scp root@172.26.159.180:/root/xzy/centreon-2.4.4.tar.gz /usr/local/src/centreon-2.4.4.tar.gz
tar zxf centreon-2.4.4.tar.gz
cd centreon-2.4.4
./install.sh -i
GPL许可证，填写y
确定安装centreon几部分模块，全部填写y
Centreon etc directory更改为/usr/local/centreon/etc
Centreon variable library directory更改为/usr/local/centreon/var/lib
RRD perl module installed [RRDs.pm]更改为/usr/lib64/perl5/vendor_perl/RRDp.pm
(可以通过 rpm -ql rrdtool-perl 确认，最好验证，不一定是上面的路径)
PEAR [PEAR.php]更改为/usr/share/pear/PEAR.php
(可以通过 rpm -ql php-pear 确认)
What is the Monitoring engine log directory?==>/usr/local/centreon/log
default to [/usr/lib/nagios/plugins] ==>/usr/local/nagios/libexec
What is the Monitoring engine init.d script ?
> /etc/init.d/nagios
What is the Monitoring engine binary ?
> /usr/local/nagios/bin/nagios
What is the Monitoring engine configuration directory ?
> /usr/local/nagios/etc
Where is the configuration directory for broker module ?
> /usr/local/nagios/etc
Where is the init script for broker module daemon ?
> /etc/init.d/ndo2db
填写相关项目
NDO ndomod binary更改为/usr/local/nagios/bin/ndomod.o
Centreon Run Dir directory更改为/usr/local/centreon/var/run
CentStorage RRD directory更改为/usr/local/centreon/var/lib
CentPlugins lib directory更改为/usr/local/centreon/var/lib/centplugins
6)、启动相关服务
cd ../
/etc/init.d/httpd start
/etc/init.d/mysqld start
mysqladmin -u root password '_Y-93iE2'
/etc/init.d/ndo2db start
7)、WEB界面安装
浏览器输入：http://172.27.206.7/centreon/
按照提示完成设置。最后可以登录界面了。
8)启动相关服务
/etc/init.d/nagios start
/etc/init.d/ndo2db restart
/etc/init.d/centcore start
/etc/init.d/centstorage start
/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d
当前遇到的问题是：服务端nagios服务启动问题。
