指导参考网址：http://docs.icinga.org/icinga2/latest/doc/module/icinga2/toc
所需rpm包下载网址：http://packages.icinga.org/epel/
https://packages.icinga.org/epel/6/release/noarch/ （icingaweb2包）
php-intl、php-pecl-imagick需要单独下
需要的包：libboost_system1、libboost_thread1、libboost_regex1、libedit、boost-license1、libboost_program_options1、icinga2、icinga2-bin、icinga2-common、icinga2-ido-MySQL、icingaweb2、icingaweb2-common、icingaweb2-vendor-*（6个）、php-icinga、icingacli、nagios-plugins
安装httpd：
# yum install httpd
# yum install php php-gd （注意php版本和icinga2等匹配，如果不匹配就得手动下重装了）
php相关包有：php、php-cli、php-common、php-gd、php-intl、php-mysql、php-pdo、php-xml
额外包：fping、perl-NET-SNMP、perl-Crypt-DES （需先下载好）
# rpm -i libboost* boost-license （需先下载好）
# rpm -i libicu-4.2.1-8.2.x86_64.rpm (需先下载好）
# rpm -i icinga2* php-icinga （需先下载好）
# rpm -i perl-Crypt-DES perl-NET-SNMP fping perl-Digest-SHA1 perl-Digest-HMACperl-Socket6
# rpm -i nagios-plugins-1.4.16-1.el6.rf.x86_64.rpm （如果报依赖不想处理的话加--nodeps）
如果提示下面相关报错，做下链接即可
# ln -s /usr/lib64/libicui18n.so.42 /usr/lib64/libicui18n.so.36
# ln -s /usr/lib64/libicuuc.so.42 /usr/lib64/libicuuc.so.36
# ln -s /usr/lib64/libicudata.so.42 /usr/lib64/libicudata.so.36
# ln -s /usr/lib64/libMagickWand.so.2 /usr/lib64/libMagickWand.so.5
Log路径：/var/log/icinga2/icinga2.log
安装mysql：
# yum install mysql-server
# service mysqld start
# mysql-u root
# mysql -u root -p’xxxx’
# mysql -u root -p’xxxx’ icinga2
# rpm -i icingaweb2-*
# service icinga2 restart
# service httpd restart
# vi /etc/php.ini （查找timezone）
date.timezone = Asia/Shanghai
:wq
# service httpd restart （不然访问页面时会报timezone错误）
页面访问：http://ip/icingaweb2
暂时还不能登录，点击账号上面的web-basedsetup-wizard
然后照着提示在命令行里操作：
# icingacli setup config directory --group icingaweb2
# icingacli setup token create
# su -c"mkdir -m 2770 /etc/icingaweb2;chgrp icingaweb2 /etc/icingaweb2;head -c 12 /dev/urandom | base64 | tee /etc/icingaweb2/setup.token;chmod 0660 /etc/icingaweb2/setup.token;"
然后将乱码贴到页面上
模块部分全勾，然后会提示the phpconfig 'date.timezone' is not defined
# vi/etc/php5/apache2/php.ini
date.timezone= Asia/Shanghai （默认是注释掉的）
:wq
# service httpd restart
再点击refresh即可（其它***提示可忽略）——Database——将数据库、用户名等补上,勾上Skip Validation——设置管理账号及密码
如果提示没有icingaweb_user表，就手动创建下吧，命令如下：
use icinga2;
create table icingaweb_user (name varchar(64) not null,activetinyint(1) not null,password_hash varbinary(255) not null,ctime timestamp,mtimetimestamp);
如果页面显示“icinga is currently notup and running”，一是看/etc/icinga2/features-enabled/下是否有ido-mysql.conf，如果没有从/etc/icinga2/features-available/处链接过来即可；二是看/var/log/icinga2/icinga2.log提示
添加主机：
# cd /etc/icinga2/conf.d/
# vi shhudson.conf
object Host"hudson15" {
import "generic-host"
address = "10.0.0.2"
vars.os = "Linux Servers"
vars.sla = "24x7"
}
:wq
# chown icinga:icinga shhudson.conf
# service icinga2 restart
此时页面上就会显示“hudson15”主机
添加主机组：
# cd /etc/icinga2/conf.d/
# vi groups.conf
object HostGroup"shhudson" {
display_name = "shhudson"
assign where host.vars.os =="shhudson"
}
:wq
# service icinga2 restart
此时页面上就会显示“shhudson”主机组
安装nrpe（管理多台主机）
# rpm -i nagios-plugins-nrpe-2.14-1.el6.rf.x86_64.rpm（需先下载好）
此时会生成/usr/lib64/nagios/plugins/check_nrpe
# /usr/lib64/nagios/plugins/check_nrpe-H 10.0.0.5 （显示NRPE v2.12即为正常，前提是客户端已安装nrpe插件）
配置nrpe
说明：空间大小以MB为单位，KMB为1000MB（1GB），MMB为1000000MB（即1TB）
另check_mem.pl需额外下载插件使用（步骤略）
# vi /etc/icinga2/conf.d/templates.conf
templateCheckCommand "nrpe-common" {
import "plugin-check-command"
command = [ PluginDir +"/check_nrpe" ]
arguments = {
"-H" = "$nrpe_address$"
"-p" = "$nrpe_port$"
"-c" = "$nrpe_command$"
"-a" = {
value = "$nrpe_args$"
repeat_key = false
order = 1
}
}
vars.nrpe_address = "$address$"
vars.nrpe_port = 5666
}
objectCheckCommand "nrpe-disk" {
import "nrpe-common"
vars.nrpe_command = "check_disk"
}
objectCheckCommand "nrpe-load" {
import "nrpe-common"
vars.nrpe_command = "check_load"
}
objectCheckCommand "nrpe-users" {
import "nrpe-common"
vars.nrpe_command = "check_users"
}
:wq
# vi/etc/icinga2/conf.d/services.conf
applyService "nrpe-disk" {
import "generic-service"
check_command = "nrpe-disk"
assign where host.address
}
apply Service"nrpe_load" {
import "generic-service"
check_command = "nrpe-load"
assign where host.address
}
applyService "nrpe_users" {
import "generic-service"
check_command = "nrpe-users"
assign where host.address
}
:wq
# vi /etc/icinga2/conf.d/shhudson.conf
object Host"hudson15" {
import "generic-host"
address = "10.0.0.2"
vars.os = "Linux Servers"
vars.sla = "24x7"
}
:wq
# service icinga2restart
命令使用：
# /usr/lib64/nagios/plugins/check_nrpe -H shming03 -c check_disk -a 10,20
客户端安装nrpe插件：
Ubuntu：
# useradd -s /sbin/nologin -M nagios
# apt-get install nagios-nrpe-server nagios-plugins
编辑nrpe配置文件
# vi /etc/nagios/nrpe.cfg
allowed_hosts=127.0.0.1,10.0.0.2 (默认为allowed_hosts=127.0.0.1)
dont_blame_nrpe=1
:wq
启动nrpe
# service nagios-nrpe-server start
Redhat:
# rpm -i perl-Crypt-DES perl-NET-SNMP fping perl-Digest-SHA1 perl-Digest-HMACperl-Socket6 （需要下载，有的本地yum里有）
# rpm -i nagios-plugins-1.4.16-1.el6.rf.x86_64.rpm
# rpm -i nagios-nrpe-2.14-1.el6.rf.x86_64.rpm （需要下载）
# vi /etc/nagios/nrpe.cfg （command都需加sudo）
command[check_cpu]=sudo /usr/lib64/nagios/plugins/check_snmp_load.pl -H 127.0.0.1 -C 'xxxxx' -w 80 -c 90 --perf
allowed_hosts=127.0.0.1,10.0.0.2 (默认为allowed_hosts=127.0.0.1)
dont_blame_nrpe=1
:wq
启动nrpe
# service nrpe start
# vi /etc/sudoers （此处不配会报NRPE: Unable to read output）
nagiosALL=(ALL) NOPASSWD:/usr/lib64/nagios/plugins/*
#Defaults requiretty
:wq
记得开防火墙端口(199、5666，即snmp和nrpe)
# vi /etc/sysconfig/iptables
-A INPUT–p tcp –dport 199 –j ACCEPT
-A INPUT–p tcp –dport 5666 –j ACCEPT
:wq
# service iptables restart
安装pnp4nagios：
下载网址:https://github.com/Icinga/icinagweb2-module-pnp4ngaios
下载后解压并改名为pnp4nagios，剪切到/usr/share/icingaweb2/modules/下
重启icinga2后，到页面——Configuration——Modules——pnp4nagios——enable
下载pnp4nagios rpm包
# rpm –i pnp4nagios –nodeps
# rpm –i perl-rrdtool –nodeps
安装后会自动生成/etc/httpd/conf.d/pnp4ngaios.conf （如果不设置用户、密码，可在此处取消）
主配置文件路径：/etc/pnp4ngaios
还有1路径：/usr/share/nagios/html/pnp4ngios （实际web路径）
# vi/etc/pnp4nagios/npcd.cfg
User = icinga
Group =icinga
Perfdata_spool_dir=/var/spool/icinga2/perfdata
:wq
# vi/etc/icinga2/conf.d/templates.conf
template Host "pnp-hst" {
action_url ="/pnp4nagios/graph?host=$HOSTNAME$'rel='/pnp4nagios/popup?host=$HOSTNAME$&srv=_HOST_"
}
template Service "pnp-svc" {
action_url ="/pnp4nagios/graph?host=$HOSTNAME$&srv=$SERVICEDESC$'rel='/pnp4nagios/popup?host=$HOSTNAME$&srv=$SERVICEDES$"
}
template Host "generic-host" {
max_check_attempts = 3
check_interval = 1m
retry_interval = 30s
check_command = "hostalive"
import "pnp-hst"
}
template Service "generic-service" {
max_check_attempts = 5
check_interval = 1m
retry_interval = 30s
import "pnp-svc"
}
:wq
# chown icinga /var/lig/pnp4nagios
# icinga2 feature enable perfdata
# service httpd restart
# service npcd restart
# service icinga2 restart
可先访问下http://ip/pnp4ngaios是否正常，不能正常显示的话就看httpd的log吧
发报警邮件
说明：默认为30分钟发一次
# vi/etc/icinga2/conf.d/users.conf
Email = zhi.yang@ming.com
:wq
# vi /etc/icinga2/conf.d/shhudson.conf
object Host"hudson15" {
import "generic-host"
address = "10.0.0.2"
vars.os = "Linux Servers"
vars.sla = "24x7"
vars.notification[“mail”] = {
groups = [ “icingaadmins” ]
}
}
:wq
# service icinga2 restart
# vi/etc/postfix/main.cf
Relayhost= 10.0.1.5 （公司的邮箱服务器）
:wq
# service postfix restart
可手动发邮件验证下：
# mail –s“aa” zhi.yang@ming.com < aa
# cat/var/log/maillog
调整发邮件级别：
# vi/etc/icinga2/conf.d/templates.conf
调整states部分即可
:wq
可以对user进行定制（多邮件人通知）：
# vi /etc/icinga2/conf.d/users.conf
object User "bj"
import "generic-user"
states = [ OK,Critical] （此处对报警类型也可定制）
email = "zhi.yang@ming.com,ming.yang@ming.com" （此处可以写多人）
:wq
# vi /etc/icinga2/conf.d/shhudson.conf
object Host"hudson15" {
import "generic-host"
address = "10.0.0.2"
vars.os = "Linux Servers"
vars.sla = "24x7"
vars.notification[“mail”] = {
users = [ “bj” ] (多user中间用“，”隔开)
}
}
:wq
监控存储（check-netapp-ng.pl）：
下载网址：https://github.com/ranl/monitor-utils/blob/master/nagios/check-netapp-ng.pl
# mv check-netapp-ng.pl/usr/lib64/nagios/plugins/
# chmod +x /usr/lib64/nagios/plugins/check-netapp-ng.pl
使用：
卷：
# /usr/lib64/nagios/plugins/check-netapp-ng.pl–H 10.0.0.3 –C public –T DISKUSED –vol /vol/Backup –w 90 –c 95
整体状态：
# /usr/lib64/nagios/plugins/check-netapp-ng.pl–H 10.0.0.3 –C public –T GLOBALSTATUS
CPU:
# /usr/lib64/nagios/plugins/check-netapp-ng.pl–H 10.0.0.3 -C public -T CPULOAD –w 90 –c 95
用icinga2监控存储整体状态（单个卷超过98%会报警的）：
# vi/etc/icinga2/conf.d/templates.conf
objectCheckCommand "check-netapp" {
import "plugin-check-command"
command = [ PluginDir +"/check-netapp-ng.pl" ]
arguments = {
"-H" = "$address$"
"-C" = "$snmp$"
"-T" = "$checktype$"
"-w" = "$warn$"
"-c" = "$crit$"
}
}
:wq
# vi/etc/icinga2/conf.d/services.conf
applyService "check_netapp" {
import "generic-service"
check_command = "check-netapp"
vars.snmp="public"
vars.checktype="GLOBALSTATUS"
vars.vol="/vol/Backup/"
assign where host.vars.os =="netapp"
}
:wq
# vi/etc/icinga2/conf.d/netapp.conf
objectHost "shnas7" {
import "generic-host"
address = "10.0.1.21"
vars.os = "netapp"
vars.sla = "24x7"
vars.notification["mail"] = {
groups = [ "icingaadmins" ]
}
}
:wq
# chownicinga:icinga /etc/icinga2/conf.d/netapp.conf
# service icinga2 restart
监控windows主机：
需要借助3个插件：check_snmp_storage.pl、check_snmp_memory.pl、check_snmp_load.pl
下载网址：
http://nagios.manubulon.com/check_snmp_load.pl
https://exchange.nagios.org/directory/Plugins/Network-Protocols/SNMP/Simple-snmp-memory-check/details
https://github.com/DNSmichi/manubulon-snmp/blob/master/plugins/check_snmp_storage.pl
使用：
# ./check_snmp_load.pl -H 10.0.0.3 -C public -w 80 -c 90
# ./check_snmp_memory.pl -H 10.0.0.3 -C public -w 80 -c 90

set_if = "$perf$"
}
}
}
:wq
# vi /etc/icinga2/conf.d/services.conf

vars.os = "shwin"
vars.sla = "24x7"
vars.notification[“mail”] = {
users = [ “bj”，“aa” ] (多user中间用“，”隔开)
}
}
:wq
# chown icinga:icinga /etc/icinga2/conf.d/shwin.conf
修改groups.conf略
# service icinga restart
