LAMP+Nagios+Ndoutils+Centreon 64位操作系统安装
LAMP安装
安装yum 源
1. rpm -ivh rpmforge-release-0.5.2-2.el5.rf.x86_64.rpm
2. rpm -ivh epel-release-5-4.noarch.rpm
3. rpm -ivh remi-release-5-8.el5.remi.noarch.rpm
yum安装：
#yum install httpd
#yum install mysql mysql-server mysql-devel openssl-devel perl-DBD-MySQL
#yum install php php-mysql php-gd
部分软件包安装
安装 PHP附属包：
#yum install php-pear php-snmp php-common php-ldap php-xml php-gd php-mbstring
安装PERl包：
#yum install perl-DBI perl-Config-IniFiles perl-Crypt-DES perl-Digest-HMAC perl-Digest-SHA1 perl-GD perl-IO-Socket-INET6 perl-Net-SNMP perl-rrdtool perl-Socket6 perl-Config-IniFiles
安装GD Modules：
#yum install gd gd-devel
安装其余软件包：
#yum install libpng-devel dmidecode lm_sensors libpng zlib freetype cairo pango libxml2 fontconfig fping graphviz gcc-c++ glib2-devel
Yum install glib
Yum install fping
Yum install graphviz.x86_64
以上软件包如果本机中未能自带，请登录 上自行下载。
（当需要安装librrd.so.2()(64bit时，下载zenoss-2.3.3.el5.x86_64.rpm
安装RRDTOOL：
rpm -e rrdtool-1.4.7-1.el5.rf.x86_64 perl-rrdtool-1.4.7-1.el5.rf.x86_64
#rpm –ivh rrdtool-1.2.19-1.el5.kb.x86_64.rpm
#rpm –ivh rrdtool-devel-1.2.19-1.el5.kb.x86_64.rpm
#rpm –ivh rrdtool-doc-1.2.19-1.el5.kb.x86_64.rpm
#rpm –ivh rrdtool-perl-1.2.19-1.el5.kb.x86_64.rpm
#rpm –ivh rrdtool-php-1.2.19-1.el5.kb.x86_64.rpm
#rpm –ivh rrdtool-python-1.2.19-1.el5.kb.x86_64.rpm
#rpm –ivh rrdtool-tcl-1.2.19-1.el5.kb.x86_64.rpm
安装PEAR模块：
因为之前已经安装过php-pear包，pear的主目录已经产生，但是Centreon还需要加载一些pear模块才能工作。
pear upgrade --force
#pear install Archive_Tar Auth_SASL Console_Getopt Date DB DB_DataObject DB_DataObject_FormBuilder HTML_Common HTML_QuickForm_advmultiselect HTML_QuickForm_ElementGrid HTML_Table HTML_QuickForm HTTP HTTP_Request Image_Canvas Image_Color Image_Graph Image_GraphViz Log Mail Mail_Mime Math_BigInteger MDB2 Net_DIME Net_IDNA Net_Ping Net_SMTP Net_Socket Net_Traceroute Net_URL Numbers_Roman Numbers_Words SOAP Structures_Graph Validate XML_RPC
#pear list ------ 查看安装了哪些模块
pear install channel://pear.php.net/Image_Canvas-0.3.5
pear install channel://pear.php.net/Image_Graph-0.8.0
pear install channel://pear.php.net/Numbers_Words-0.16.4
pear install channel://pear.php.net/SOAP-0.13.0
pear install channel://pear.php.net/Validate-0.8.5
pear install channel://pear.php.net/HTML_QuickForm_ElementGrid-0.1.2
pear install channel://pear.php.net/NET_IDNA-0.8.1
pear install channel://pear.php.net/Net_Traceroute-0.21.3
安装SNMP：
#yum install net-snmp net-snmp-utils net-snmp-devel net-snmp-perl
配置SNMP：
#vim /etc/snmp/snmpd.conf 将x.x.x.x换成运行nagios服务器的IP地址：
com2sec notConfigUser x.x.x.x public
access notConfigGroup”” any noauth exact all none none
view all included .1 80
安装nagios Ndoutils安装
=====================yum 安装===================
yum install nagios nagios-plugins nagios-plugins-nrpe nagios-devel nagios-nrpe nagios
安装完的插件都在/usr/lib64/nagios/plugins下，以后centreon插件也会在这个目录下。
输入 可以看到如下界面：
/usr/bin/htpasswd -c /etc/nagios/htpasswd.users nagios (如无法登陆需设置用户名密码、用户名或为nagiosadmin)
设置密码
#出现这个画面表示nagios安装成功
#执行service nagios start操作可以看到nagios监控的本机的状态
（nagios目录：/etc/nagios/
插件目录：/usr/lib64/nagios/plugins
给nagios用户开权限，让他能够查看信息！
# vim /usr/local/nagios/etc/cgi.cfg
在所有的nagiosadmin后面添加nagios
/etc/init.d/nrpe start）
Ndoutils安装
#tar -zxf ndoutils-1.4b9.tar.gz
#cd ndoutils-1.4b9
#./configure --prefix=/usr/local/nagios/ \
--enable-mysql \
--disable-pgsql \
--with-ndo2db-user=nagios \
--with-ndo2db-group=nagios
#make
#make install
Cd config
Copy ndo2db.cfg to /etc/nagios/ndo2db.cfg
##### find that file from current monitoring machine!!!!!!!!!!!
（启动ndo2db守护进程
/usr/local/nagios/bin/ndo2db-3x -c /usr/local/nagios/etc/ndo2db.cfg
对于不同Nagios版本，NDOUtils有不同的启动程序，ndo2db-2x对应Nagios的2.X版本，ndo2db-3x对应Nagios的3.X版本，
）
Centreon安装
#tar -zxf centreon-2.1.9.tar.gz
#cd centreon-2.1.9
#./install.sh -i
#每一步都要看好要安装的东西以及目录，安装目录默认的就选默认就好了，有的需要自己指定目录：RRDs，PEAR.php，ndomod.o
#find / -name RRDs.pm
/usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux-thread-multi/RRDs.pm
#find / -name PEAR.php
/usr/share/pear/PEAR.php
/usr/lib64/nagios
/etc/nagios
/var/nagios
#find / -name ndomod.o
/usr/local/nagios/bin/ndomod.o
# ./install.sh –i
Centreon安装完成后，你可以通过来访问。
Is running 无法启动时
执行 /usr/sbin/ndo2db -c /etc/nagios/ndo2db.cfg
#安装后在网址中输入 进入Centreon web 配置界面
#填写mysql数据库访问密码，填写ndo的用户及密码
#创建centreon登录时的账号和密码
#登录后的界面：
#安装完成
C、配置cgi.cfg
D、应用更改
问题解决：
解决不能显示服务及host的数量
添加默认的用户名
参考：
[root@localhost centreon-2.2.2]# ./install.sh -i

Nagios/Centreon monitoring Server Server setup Screencopy:
Ubuntu 客户端安装 (remote server installation and setup)
#apt-cache search nagios-nrpe-server nagios-nrpe-plugin
And install above packages if they don’t exist
#sudo apt-get install nagios-nrpe-server nagios-nrpe-plugin
Then, check and edit the nrpe configuration file at /etc/nagios/nrpe.cfg (default location)
Such as
#sudo vi /etc/nagios/nrpe.cfg (in the following)
Append the Nagios server ip in the following
allowed_hosts=127.0.0.1,your-nagios-server-ip
allowed_hosts=127.0.0.1,192.168.10.247,192.168.10.201
Once finishing the edit nrpe.cfg, that nrpe process needs restart, so do the following:
#ps aux | grep nrpe
and find the nrpe process ID and kill it, then restart the nrpe process. Then the new monitoring should be added in our system such as
#kill “nrpe-process-id”
And start nrpe process as
/usr/sbin/nrpe -c /etc/nagios/nrpe.cfg -d
Once finishing the editing the nrpe.cfg do a basic test
As
#check_nrpe –H remote-machibe-IP
Before adding the monitoring variable in our monitoring server, we have to edit the remote client /etc/nagios/nrpe.cfg file (this is a default location and it might change to other location depending on how you install nagios-nrpe-plugin …
#vi /etc/nagios/nrpe.cfg
For some system, there might need to download some packages such as ksh, sysstat or perl
sudo apt-get install ksh
sudo apt-get install sysstat
For perl package go to to search related perl packages
Here are some examples that we add the following command lines for our remote ubuntu server:
command[check_cpu_234]=/usr/local/nagios/libexec/check_cpu_stats.sh -w 70,40,30 -c 90,60,40
command[check_mem_234]=/usr/local/nagios/libexec/check_memory.pl -w 100: -c 2%
command[check_diskio]=/usr/lib/nagios/plugins/contrib/check_diskio --device=/dev/sda1 --critical=30 --warning=50
command[check_tcptraffic]=/usr/lib/nagios/plugins/contrib/check_tcptraffic --warning=20971520 --critical=83886080 --interface=eth0 --speed=10
For more monitoring Tools, please go to to search free monitor tools.
Here for the shell script check_cpu_stats.sh and its command parameter meaning, please go to that script to see its document or use
#man iostat
to see the detail information. In the above check_cpu_stats.sh script input parameter, we take its default as -w 70,40,30 -c 90,60,40. Here w: meaning warning threshold and c: meaning critical threshold. The meaning of above parameters is corresponding to USER, SYSTEM, IOWAIT about which the cpu spends time on each category.
centreon安装失败后的卸载
Java代码
# rm -rf /usr/local/centreon
# rm -rf /etc/centreon
# rm -rf /etc/httpd/conf.d/centreon.conf
# rm -rf /var/lib/centreon
# ./install -i
另外一个卸载脚本
Java代码
echo 'find / -name centreon -type d | grep -v mysql | grep -v samba | xargs rm -rf...'
findall centreon -type d | grep -v mysql | grep -v samba | xargs rm -rf
echo 'locate centreon | grep -v mysql | grep -v samba | xargs rm -rf...'
locate centreon | grep -v mysql | grep -v samba | xargs rm -rf
updatedb
echo "locate centreon's result:"
locate centreon
监控工作主要由nagios完成?再通过ndo2db写入数据库?最后由centreon调用显示出来
启动服务：
/etc/init.d/nrpe restart
/usr/local/nagios/bin/ndo2db -c /etc/nagios/ndo2db.cfg
/etc/init.d/httpd restart
/etc/init.d/nagios restart
/etc/init.d/centcore restart
/etc/init.d/centstorage restart
Centreon汉化
1.下载语言文件 # wget
2.创建语言目录 # mkdir -p /usr/local/centreon/www/locale/zh_CN/LC_MESSAGES/
3.移劢下载的messages.mo至第2步创建的目录 # mv messages.mo /usr/local/centreon/www/locale/zh_CN/LC_MESSAGES/
4.登录centreon?点击administartors?再点option?迚入”my account”?更改语言为zh_CN保存即可。
Nagios插件目录：/usr/lib64/nagios/plugins
配置文件目录：/etc/nagios/objects
被监控端nrpe目录：/etc/nagios
被监控端插件目录：/usr/lib64/nagios/plugins
/usr/local/nagios/libexec/check_nrpe -H 192.168.18.181 -c check_users
为10.201添加监控ping命令步骤
1、 下载监控脚本
cd /usr/lib64/nagios/plugins(监控端和被监控端都要有此脚本)
wget
chown nagios:nagios check_ping
chmod +x check_ping
2、 添加主机
（检测命令要选中check_host_alive，否则会显示主机为down）
3、 定义命令
4、 增加服务
增加check_ping 服务
generic-service为服务模板，以后配置基本都要用到它。
5、 关联主机
配置——服务——关系
6、 被监控端定义command字段
在被监控端，编辑:vim /etc/nagios/nrpe.cfg，添加command字段
被监控端重启nrpe服务
ps aux | grep nrpe
kill 32162
/usr/sbin/nrpe -c /etc/nagios/nrpe.cfg –d
在被监控端测试脚本
在监控机上远程测试
（注意：写command字段和测试时，参数要写正确）
7、 激活配置，重启服务
8、 查看监控内容
参考：
出现问题：
1、CHECK_NRPE: Socket timeout after 10 seconds.
解决方法：
测试NRPE daemon
netstat -ln |grep 5666
tcp 0 0 0.0.0.0:5666 0.0.0.0:* LISTEN
修改防火墙规则,开放tcp 5666端口
