nagios./configure prefix=/usr/local/nagios#默认路径Make allMake install #主程序Make install-init#启动脚本Make install-commandmode#目录全选Make install-config#事例配置文件Make install-webconf#web配置文件1.4.1 nagios用户认证注意：需要apache支持且htpasswd为apache的一个命令Cat /etc/httpd/conf.d/nagios.conf#查看有nagios配置的httpd配置文件htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin#添加认证用户chown nagios.nagios /usr/local/nagios/etc/htpasswd.users #给予nagios权限vi /usr/local/nagios/etc/cgi.cfg#编辑基本认证配置 默认nagiosadmin1.4.2 启动检查添加服务chkconfig nagios onchkconfig httpd on启动Service nagios startService httpd start访问7/nagios使用nagiosadmin登录，查看系统状态，但会提示缺少plugin。1.5 Nagios-plugins插件安装Service nagios stopTar zxvf nagios-plugins-1.4.16.tar.gzCd nagios-plugins-1.4.16./configure prefix=/usr/local/nagios#与主文件路径一致MakeMake install1.6 Nrpe插件安装注意：需要openssl，xinetd支持Tar zxvf nrpe-2.13.tar.gzCd nrpe-2.13./configure prefix=/usr/local/nagios#与主文件路径一致Make allMake intallMake install-pluginMake install-daemon#添加守护Make install-daemon-configMake install-xinetd#添加到xinetd伴随服务中Vi /etc/servicesNrpe5666/tcp#nrpe#添加服务端口Service xinetd restart/usr/local/nagios/libexec/check_nrpe H localhost#测试 显示版本信息即为正常注意设置nagios 的报警邮件，其反应出来的错误是：“CHECK_NRPE: Socket timeout after 10 seconds”。但服务器检查是时候均是正常的nrpe 进程执行某些脚本可能是大于10秒钟，而默认的是10秒钟。所以会发报警信息，解决的方法如下：define commandcommand_name check_nrpecommand_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$ -t 30 # 加上一个 -t 30 指定时间为 30 秒重启nagios 和apache即可1.7 启动测试Service nagios start访问7/nagios查看本地系统状态，一般除了HTTP警告外其他均正常。2 pnp4nagios出图通过整合pnp4nagios,ndoutils,nconf提供了关于nagios的一套完整的配置方案基础环境（额外，非之前配置的）安装rrdtool工具，注意依赖包问题，我是使用系统自带版本类别关于配置模式可以自选一种rpm ivh rrdtool-1.3.8-6.el6.x86_64.rpmrpm ivh rrdtool-perl-1.3.8-6.el6.x86_64.rpmrpm ivh rrdtool-devel-1.3.8-6.el6.x86_64.rpm2.1 安装pnp4nagiostar zxvf pnp4nagios-0.6.21.tar.gzcd pnp4nagios-0.6.21./configure -prefix=/usr/local/pnp4nagiosmake

check_nwstat.cfg重启服务etc/init.d/npcd restart2.2 Synchronous Mode配置修改 nagios 的配置文件，该模式优点，简单。打开performance_data,打开注视项rootnagios # vi /usr/local/nagios/etc/nagios.cfgprocess_performance_data=1 host_perfdata_command=process-host-perfdataservice_perfdata_command=process-service-perfdata2.2.1 commands.cfg设置修改command设置，如果系统在编译时候都安装上的时候，可以先注释下。rootnagios # vi /usr/local/nagios/etc/objects/commands.cfg#添加，Synchronous Mode# process-host-perfdata command definitiondefine command command_name process-host-perfdata command_line /usr/local/pnp4nagios/libexec/process_perfdata.pl -d HOSTPERFDATA # process-service-perfdata command definitiondefine command command_name process-service-perfdata command_line /usr/local/pnp4nagios/libexec/process_perfdata.pl 2.2.2 templates.cfg设置添加图像按钮模版，镶嵌在nagios页面上。只要在主机类型设置给以下就可以看到页面上的按钮了。方法一：绑定到监控组generic-service和linux-server中，但部分只是检查正常不出数据的检查，点击图标的错误页面。rootnagios # vim /usr/loac/nagios/etc/object/templates.cfg# 更改generic-service和linux-server,define host namegeneric-serviceaction_url /pnp4nagios/graph?host=$HOSTNAMEprocess_perf_data 0define service name linux-serveraction_url /pnp4nagios/graph?host=$HOSTNAME$&srv=$SERVICEDESC$process_perf_data 0 方法二：也可以选择添加额外的监控组rootnagios # vim /usr/loac/nagios/etc/object/templates.cfgdefine host namehost-pnpaction_url /pnp4nagios/graph?host=$HOSTNAMEprocess_perf_data 0define service name sev-pnpaction_url /pnp4nagios/graph?host=$HOSTNAME$&srv=$SERVICEDESC$process_perf_data 0 然后在编辑被监控主机的时在use后面跟上即可。使用逗号分隔,可确保在配置每台主机的时候对可对比数据进行显示。rootnagios # vim /usr/local/nagios/etc/objects/host23.cfgdefine host uselinux-server,host-pnphost_name host23aliasOracle 11gR2address 3 define service use generic-service,sev-pnphost_name host23service_description Oracle Cache Check check_command check_nrpe!check_oracle_cache 2.3 Bulk Mode配置编辑nagios.cfg配置文件，其他于之上设置一样。两种模式自选一种即可。该模式优点：他会写入spool文件中，校对显示。rootnagios # Vi /usr/local/nagios/etc/nagios.cfgprocess_performance_data=1# service performance data#service_perfdata_file=/usr/local/pnp4nagios/var/service-perfdataservice_perfdata_file_template=DATATYPE:SERVICEPERFDATAtTIMET:$TIMET$tHOSTNAME:$HOSTNAME$tSERVICEDESC:$SERVICEDESC$tSERVICEPERFDATA:$SERVICEPERFDATA$tSERVICECHECKCOMMAND:$SERVICECHECKCOMMAND$tHOSTSTATE:$HOSTSTATE$tHOSTSTATETYPE:$HOSTSTATETYPE$tSERVICESTATE:$SERVICESTATE$tSERVICESTATETYPE:$SERVICESTATETYPE$service_perfdata_file_mode=aservice_perfdata_file_processing_interval=15service_perfdata_file_processing_command=process-service-perfdata-file#

# vi /usr/loac/nagios/etc/object/commands.cfgefine command command_name process-service-perfdata-file command_line /usr/local/pnp4nagios/libexec/process_perfdata.pl

-bulk=/usr/local/pnp4nagios/var/host-perfdata其他模式这里做介绍，可以查看/pnp-0.6/config2.4 加载测试重启httpd和nagios服务Service httpd reloadService nagios reload访问7/nagios查看界面状态，可以看到pnp4nagios的按钮，然后点击可以进入install.php页面，并显示相关安装信息，如果有未安装的，请按指示安装。均正常后，页面最下方是绿色信息提示可以删除install.php页面，然后我们进行重命名即可Mv /usr/local/pnp4nagios/share/install.php /usr/local/pnp4nagios/share/install.php.bak 重新访问页面，在点击图标的时候就可以显示具体图像了。3 NDOutils整合Ndoutils即为将nagios的配置文件信息转存储到mysql中的插件。需要mysql及ndoutils即可设置mysql启动service mysqld startchkconfig mysql on数据库设置mysql -e “create database nagios;”mysql -e “grant all on nagios.* to nagioslocalhost identified by 123456;”Mysql -e “flush privileges;”基础编译安装tar zxvf ndoutils-1.5.2.tar.gzcd ndoutils./configure
