#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 http://pear.php.net/get/PEAR-1.9.0
#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

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
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http://IP/nagios即可看到nagios监控界面
{
/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
sed -i 's/nagiosadmin/nagios/g' /etc/nagios/cgi.cfg 打开查看权限
service nagios restart
service httpd restart
service mysqld restart
#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）
} //{}中内容可以不配置
Ndoutils安装
#tar -zxf ndoutils-1.4b9.tar.gz
#cd ndoutils-1.4b9
#./configure --prefix=/usr/local/nagios/ \
--enable-mysql \
--disable-pgsql \

C、配置cgi.cfg
D、应用更改
参考：http://www.linuxidc.com/Linux/2011-04/34031p2.htm
出现问题：
1、不显示主机列表
ps aux | grep ndo2db
启动ndo2db服务
locate ndo2db
/usr/local/nagios/bin/ndo2db -c /etc/nagios/ndo2db.cfg
参考：
http://wenku.baidu.com/view/98ba2b1752d380eb62946dd0.html
2、不能显示服务和主机数量
==========
Ubuntu 客户端安装 (remote server installation and setup)
#sudo apt-get install nagios-nrpe-server nagios-nrpe-plugin
#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
重启nrpe
#ps aux | grep nrpe
#kill “nrpe-process-id”
And start nrpe process as
/usr/sbin/nrpe -c /etc/nagios/nrpe.cfg -d
============
centos客户端：
rpm -ivh rpmforge-release-0.5.2-2.el5.rf.x86_64.rpmrpm -ivh epel-release-5-4.noarch.rpmrpm -ivh remi-release-5-8.el5.remi.noarch.rpmyum install nagios-plugins nagios-plugins-nrpe nagios-nrpe –y
cd //usr/lib64/nagios/plugins/
vim /etc/nagios/nrpe.cfg
修改host_allow字段,添加监控机ip
/etc/init.d/nrpe restart
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 http://cacti-nagios.googlecode.com/files/messages.mo 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。
======
centreon安装失败后的卸载
# rm -rf /usr/local/centreon
# rm -rf /etc/centreon
# rm -rf /etc/httpd/conf.d/centreon.conf
# rm -rf /var/lib/centreon
/usr/lib64/nagios/plugins/check_nrpe -H 192.168.18.181
为10.201添加监控cpu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 http://------------------------------- chown nagios:nagios check_cpu.sh
chmod +x check_cpu.sh
2、 添加用户
2、添加主机
（检测命令要选中check_host_alive，否则会显示主机为down）
****4、增加服务
增加check_cpu 服务
使用check_nrpe 则不用在centreon中定义命令
定义check_nrpe命令：
配置-----命令-----增加
$USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$
check_cpu_load名字随便定义
check_cpu_234则是监控端和被监控端的nrpe.cfg中command字段中定义。
5、关联主机
配置——服务——关系
6、定义command字段
在监控端和被监控端都要编辑nrpe.cfg，定义命令，添加command字段
编辑:vim /etc/nagios/nrpe.cfg，添加command字段
command[check_users]=/usr/lib64/nagios/plugins/check_users -w 5 -c 10
command[check_load]=/usr/lib64/nagios/plugins/check_load -w 15,10,5 -c 30,25,20
command[check_disk_home]=/usr/lib64/nagios/plugins/check_disk -w 20% -c 10% -p /home
command[check_disk_sda2]=/usr/lib64/nagios/plugins/check_disk -w 20% -c 10% -p /dev/sda2
command[check_disk_sda3]=/usr/lib64/nagios/plugins/check_disk -w 20% -c 10% -p /dev/sda3
command[check_disk_sdb1]=/usr/lib64/nagios/plugins/check_disk -w 20% -c 10% -p /dev/sdb1
command[check_zombie_procs]=/usr/lib64/nagios/plugins/check_procs -w 5 -c 10 -s Z
command[check_total_procs]=/usr/lib64/nagios/plugins/check_procs -w 150 -c 200
command[check_memory]=/usr/lib64/nagios/plugins/check_memory.pl -f -w 30 -c 20
command[check_cpu_234]=/usr/lib64/nagios/plugins/check_cpu.sh -w 60 -c 80
command[check_http]=/usr/lib64/nagios/plugins/check_http -H $HOSTADDRESS$ -u $ARG1$ -w 5 -c 10
command[check_80]=/usr/lib64/nagios/plugins/check_tcp -H $HOSTADDRESS$ -p 80 -w 1 -c 5
command[check_iostat]=/usr/lib64/nagios/plugins/check_iostat -w 10 -c 20
command[check_nrpe]=/usr/lib64/nagios/plugins/check_nrpe -H $HOSTADDRESS$ -c $ARG1$
监控端重启nrpe
/etc/init.d/nrpe restart
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
配置--->nagios
8、查看监控内容
9、mysql监控举例：
监控端命令定义：
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
配置短信报警通知：
1、安装sendEmail
wget http://caspian.dotconf.net/menu/Software/SendEmail/sendEmail-v1.56.tar.gz #tar -zxvf sendEmail-v1.56.tar.gz && cd sendEmail-v1.56
#cp sendEmail /usr/local/bin
#chmod 0755 /usr/local/bin/sendEmail
2. 发送邮件测试
# sendEmail -h (查看sendMail帮助)
# sendEmail -f dba@lk.com -t encle@lk.com -s 28.4.15.18 -u "nagios测试" -m "nagios test 测试
或者将一个文件的内容作为附件发出, 并且是gb2312或utf8编码的html格式文件(可以显示中文):
#sendEmail -f dba@lk.com -t encle@lk.com -s 28.4.15.18 -u "nagios测试" -m "pls see the attachement附件" -a /var/log/messages -o message-content-type=html -o message-charset=gb2312
如果测试报错：
则后面需要加上-xu –xp参数：
各参数含义如下:
-f 表示发送者的邮箱, 可随意设置 -t 表示接收者的邮箱
-s 表示SMTP服务器的域名或者IP -u 表示邮件的主题 -m 表示邮件的内容
-xu 表示SMTP验证的用户名, 如果SMTP服务器需要验证的话就加上该参数, 一般发给外网用户则需要
-xp 表示SMTP验证的密码, 如果SMTP服务器需要验证的话就加上该参数, 一般发给外网用户则需要
3、在联系人用户里，就可以定义。
4、定义邮件发送命令：
配置--------命令----------通知
就在下面的“通知”里，结尾是email的是邮件发送命令。host是主机的报警和恢复，service是服务的报警和恢复。
以host那条命令为例说明
/usr/bin/printf "%b" "Host: $HOSTNAME$<br>Notification:
$HOSTNOTIFICATIONNUMBER$<br>Command: $HOSTCHECKCOMMAND$<br>Datetime: $LONGDATETIME$<br><br>Info: $HOSTOUTPUT$<br>$LONGHOSTOUTPUT$"
| /usr/local/bin/sendEmail -f jiankong@XXXX.com -t $CONTACTEMAIL$ -s smtp.XXXX.com -xu jiankong@XXXX.com -xp jk@XXXX -u "Host $HOSTSTATE$: $HOSTADDRESS$" -o message-content-type=html -o message-charset=utf8
主要是打红的地方调用发邮件的命令，路径是sendEmail命令，-f是发件人地址，-t是收件人地址，这里是个变量，已经定义了，就是之前那个联系人里填的，-s是邮件服务器地址，也可以填域名，-xu是邮箱账号，-xp是邮箱密码。其他的都是些邮件内容的定义，所以可以不用改。-o
message-content-type=html -o message-charset=utf8这段是防止中文乱码的。
下面这段是原来没做任何更改的命令行，供参考。
/usr/bin/printf "%b" "***** centreon Notification
*****\n\nType:$NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState:
$HOSTSTATE$\nAddress: $HOSTADDRESS$\nInfo: $HOSTOUTPUT$\nDate/Time: $DATE$" | @MAILER@ -s "Host $HOSTSTATE$ alert for $HOSTNAME$!" $CONTACTEMAIL$
下面这段是服务的。

改完之后保存，别忘了导出文件和重启nagios，让其生效。
到这里，我们的报警邮件就可以正常发出了。
为了防止单搞nagios的因为发不出邮件而头疼，这里提一下，如果按照大众版sendmail做法，那你需要在/etc/mail里面找到个access文件，里面需要添加你要发邮件的域。
比如qq邮箱，要添加qq.com进去。
============
说明：“配置短信报警通知”这一块可以不配置，centos服务器默认有sendmail,只要在定义联系人的时候写好邮箱，主机和服务通知栏中分别选中：host-notify-by-email和service-notify-by-email即能发送邮件报警，使用139邮箱可以短信通知。
监控界面如下：

D、应用更改
参考：http://www.linuxidc.com/Linux/2011-04/34031p2.htm
出现问题：
1、不显示主机列表
ps aux | grep ndo2db
启动ndo2db服务
locate ndo2db
/usr/local/nagios/bin/ndo2db -c /etc/nagios/ndo2db.cfg
参考：
http://wenku.baidu.com/view/98ba2b1752d380eb62946dd0.html
2、不能显示服务和主机数量
==========
Ubuntu 客户端安装 (remote server installation and setup)
#sudo apt-get install nagios-nrpe-server nagios-nrpe-plugin
#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
重启nrpe
#ps aux | grep nrpe
#kill “nrpe-process-id”
And start nrpe process as
/usr/sbin/nrpe -c /etc/nagios/nrpe.cfg -d
============
centos客户端：
rpm -ivh rpmforge-release-0.5.2-2.el5.rf.x86_64.rpmrpm -ivh epel-release-5-4.noarch.rpmrpm -ivh remi-release-5-8.el5.remi.noarch.rpmyum install nagios-plugins nagios-plugins-nrpe nagios-nrpe –y
cd //usr/lib64/nagios/plugins/
vim /etc/nagios/nrpe.cfg
修改host_allow字段,添加监控机ip
/etc/init.d/nrpe restart
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 http://cacti-nagios.googlecode.com/files/messages.mo 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。
======
centreon安装失败后的卸载
# rm -rf /usr/local/centreon
# rm -rf /etc/centreon
# rm -rf /etc/httpd/conf.d/centreon.conf
# rm -rf /var/lib/centreon
/usr/lib64/nagios/plugins/check_nrpe -H 192.168.18.181
为10.201添加监控cpu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 http://------------------------------- chown nagios:nagios check_cpu.sh
chmod +x check_cpu.sh
2、 添加用户
2、添加主机
（检测命令要选中check_host_alive，否则会显示主机为down）
****4、增加服务
增加check_cpu 服务
使用check_nrpe 则不用在centreon中定义命令
定义check_nrpe命令：
配置-----命令-----增加
$USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$
check_cpu_load名字随便定义
check_cpu_234则是监控端和被监控端的nrpe.cfg中command字段中定义。
5、关联主机
配置——服务——关系
6、定义command字段
在监控端和被监控端都要编辑nrpe.cfg，定义命令，添加command字段
编辑:vim /etc/nagios/nrpe.cfg，添加command字段
command[check_users]=/usr/lib64/nagios/plugins/check_users -w 5 -c 10
command[check_load]=/usr/lib64/nagios/plugins/check_load -w 15,10,5 -c 30,25,20
command[check_disk_home]=/usr/lib64/nagios/plugins/check_disk -w 20% -c 10% -p /home
command[check_disk_sda2]=/usr/lib64/nagios/plugins/check_disk -w 20% -c 10% -p /dev/sda2
command[check_disk_sda3]=/usr/lib64/nagios/plugins/check_disk -w 20% -c 10% -p /dev/sda3
command[check_disk_sdb1]=/usr/lib64/nagios/plugins/check_disk -w 20% -c 10% -p /dev/sdb1
command[check_zombie_procs]=/usr/lib64/nagios/plugins/check_procs -w 5 -c 10 -s Z
command[check_total_procs]=/usr/lib64/nagios/plugins/check_procs -w 150 -c 200
command[check_memory]=/usr/lib64/nagios/plugins/check_memory.pl -f -w 30 -c 20
command[check_cpu_234]=/usr/lib64/nagios/plugins/check_cpu.sh -w 60 -c 80
command[check_http]=/usr/lib64/nagios/plugins/check_http -H $HOSTADDRESS$ -u $ARG1$ -w 5 -c 10
command[check_80]=/usr/lib64/nagios/plugins/check_tcp -H $HOSTADDRESS$ -p 80 -w 1 -c 5
command[check_iostat]=/usr/lib64/nagios/plugins/check_iostat -w 10 -c 20
command[check_nrpe]=/usr/lib64/nagios/plugins/check_nrpe -H $HOSTADDRESS$ -c $ARG1$
监控端重启nrpe
/etc/init.d/nrpe restart
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
配置--->nagios
8、查看监控内容
9、mysql监控举例：
监控端命令定义：
command[check_mysql_connect_time]=/usr/lib64/nagios/plugins/check_mysql_health -hostname $HOSTADDRESS$ -port $ARG1$ -username $ARG2$ -password $ARG3$ -mode connection-time -w 1 -c 5被监控端命令定义：
command[check_mysql_connect_time]=/usr/lib64/nagios/plugins/check_mysql_health -hostname 127.0.0.1 -port 40238 -username eloancn -pas sword eloancn158 -mode connection-time -w 1 -c 5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
配置短信报警通知：
1、安装sendEmail
wget http://caspian.dotconf.net/menu/Software/SendEmail/sendEmail-v1.56.tar.gz #tar -zxvf sendEmail-v1.56.tar.gz && cd sendEmail-v1.56
#cp sendEmail /usr/local/bin
#chmod 0755 /usr/local/bin/sendEmail
2. 发送邮件测试
# sendEmail -h (查看sendMail帮助)
# sendEmail -f dba@lk.com -t encle@lk.com -s 28.4.15.18 -u "nagios测试" -m "nagios test 测试
或者将一个文件的内容作为附件发出, 并且是gb2312或utf8编码的html格式文件(可以显示中文):
#sendEmail -f dba@lk.com -t encle@lk.com -s 28.4.15.18 -u "nagios测试" -m "pls see the attachement附件" -a /var/log/messages -o message-content-type=html -o message-charset=gb2312
如果测试报错：
则后面需要加上-xu –xp参数：
各参数含义如下:
-f 表示发送者的邮箱, 可随意设置 -t 表示接收者的邮箱
-s 表示SMTP服务器的域名或者IP -u 表示邮件的主题 -m 表示邮件的内容
-xu 表示SMTP验证的用户名, 如果SMTP服务器需要验证的话就加上该参数, 一般发给外网用户则需要
-xp 表示SMTP验证的密码, 如果SMTP服务器需要验证的话就加上该参数, 一般发给外网用户则需要
3、在联系人用户里，就可以定义。
4、定义邮件发送命令：
配置--------命令----------通知
就在下面的“通知”里，结尾是email的是邮件发送命令。host是主机的报警和恢复，service是服务的报警和恢复。
以host那条命令为例说明
/usr/bin/printf "%b" "Host: $HOSTNAME$<br>Notification:
$HOSTNOTIFICATIONNUMBER$<br>Command: $HOSTCHECKCOMMAND$<br>Datetime: $LONGDATETIME$<br><br>Info: $HOSTOUTPUT$<br>$LONGHOSTOUTPUT$"
| /usr/local/bin/sendEmail -f jiankong@XXXX.com -t $CONTACTEMAIL$ -s smtp.XXXX.com -xu jiankong@XXXX.com -xp jk@XXXX -u "Host $HOSTSTATE$: $HOSTADDRESS$" -o message-content-type=html -o message-charset=utf8
主要是打红的地方调用发邮件的命令，路径是sendEmail命令，-f是发件人地址，-t是收件人地址，这里是个变量，已经定义了，就是之前那个联系人里填的，-s是邮件服务器地址，也可以填域名，-xu是邮箱账号，-xp是邮箱密码。其他的都是些邮件内容的定义，所以可以不用改。-o
message-content-type=html -o message-charset=utf8这段是防止中文乱码的。
下面这段是原来没做任何更改的命令行，供参考。
/usr/bin/printf "%b" "***** centreon Notification
*****\n\nType:$NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState:
$HOSTSTATE$\nAddress: $HOSTADDRESS$\nInfo: $HOSTOUTPUT$\nDate/Time: $DATE$" | @MAILER@ -s "Host $HOSTSTATE$ alert for $HOSTNAME$!" $CONTACTEMAIL$
下面这段是服务的。
/usr/bin/printf "%b" "Host: $HOSTALIAS$<br>NotifyTimes: $SERVICENOTIFICATIONNUMBER$<br>Command:
$SERVICECHECKCOMMAND$<br>Datetime: $LONGDATETIME$<br><br>Additional
Info:<br>$SERVICEOUTPUT$<br>$LONGSERVICEOUTPUT$" | /usr/local/bin/sendEmail -f jiankong@XXXX.com -t $CONTACTEMAIL$ -s smtp.XXXX.com -xu jiankong@XXXX.com -xp jk@XXXX -u "Service $SERVICESTATE$: $HOSTADDRESS$ | $SERVICEDESC$" -o message-content-type=html -o message-charset=utf8
改完之后保存，别忘了导出文件和重启nagios，让其生效。
到这里，我们的报警邮件就可以正常发出了。
为了防止单搞nagios的因为发不出邮件而头疼，这里提一下，如果按照大众版sendmail做法，那你需要在/etc/mail里面找到个access文件，里面需要添加你要发邮件的域。
比如qq邮箱，要添加qq.com进去。
============
说明：“配置短信报警通知”这一块可以不配置，centos服务器默认有sendmail,只要在定义联系人的时候写好邮箱，主机和服务通知栏中分别选中：host-notify-by-email和service-notify-by-email即能发送邮件报警，使用139邮箱可以短信通知。
