nagios 监控笔记(二) 四、nagios服务端配置与启动 1）、文件说明nagios.cfg #nagios主配置文件
cgi.cfg #cgi配置文件
commands.cfg #命令配置文件
contacts.cfg #联系人配置文件
resource.cfg #定义插件路径文件
templates.cfg、timeperiods.cfg 组，监控时间段等配置文件
linux.cfg #用户自定义文件，监控linux主机,定义主机配置文件
windows.cfg #用户自定义文件，监控windows主机,定义主机配置文件
l-services.cfg #用户自定义文件，定义linux主机服务配置文件
w-services.cfg #用户自定义文件，定义windows主机服务配置文件 2)、cgi.cfg文件配置root@nagios#cd /usr/local/nagios/etc
vi cgi.cfg #以下是需要修改的地方
authorized_for_system_information=nagiosadmin,test
authorized_for_configuration_information=nagiosadmin,test
authorized_for_system_commands=nagiosadmin,test
authorized_for_all_services=nagiosadmin,test
authorized_for_all_hosts=nagiosadmin,test authorized_for_all_service_commands=nagiosadmin,test authorized_for_all_host_commands=nagiosadmin,test
use_authentication=0 #修改为0,不然监控访问的时候会出现以下提示It appears as though you do not have permission to view information for any of the hosts you requested...If you believe this is an error, check the HTTP server authentication requirements for accessing this CGI
and check the authorization options in your CGI configuration file.3)、配置nagios.cfg文件cfg_file=/usr/local/nagios/etc/objects/commands.cfg
cfg_file=/usr/local/nagios/etc/objects/contacts.cfg
cfg_file=/usr/local/nagios/etc/objects/timeperiods.cfg
cfg_file=/usr/local/nagios/etc/objects/templates.cfg # wb config
cfg_dir=/usr/local/nagios/etc/linux #配置linux主机加载自定义文件的目录(下面包括linux.cfg、l-services.cfg文件)
cfg_dir=/usr/local/nagios/etc/windows #配置win主机加载自定义文件的 目录(包括windows.cfg、w-services.cfg) 4)、配置commands.cfg命令配置文件define command{
command_name check_nrpe
command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$
}define command{
command_name check_mysql_health #定义mysql监控命令 command_line $USER1$/check_mysql_health --hostname $ARG1$ --port $ARG2$ --username $ARG3$ --password $ARG4$ --mode $ARG5$
}
define command{
command_name notify-service-by-sms #定义飞信监控命令 command_line /usr/local/tools/install/fetion --mobile=159230***** --pwd=2255*** --to=$CONTACTPAGER$ --msg-gb="$HOSTNAME$ $SERVICEDESC$ is $SERVICESTATE$ on $TIME$ result is $SERVICEOUTPUT$" $CONTACTPAGER$
}
notify-host-by-email、notify-service-by-email这二项是定义mail报警的命令，默认文件有这二项5)、配置contacts.cfg联系人配置文件define contact{
contact_name nagiosadmin use generic-contact alias Nagios Admin service_notification_period 24x7
host_notification_period 24x7
service_notification_options w,u,c,r
host_notification_options d,u,r
service_notification_commands notify-service-by-email,notify-service-by-sms
host_notification_commands notify-host-by-email
email http://www.360doc.com/mailto:test@test.com,http://www.360doc.com/mailto:test@163.com pager 1592304****
}#email 定义联系人报警mail地址#pager 定义联系人报警手机号码#notify-service-by-email、notify-service-by-sms、notify-host-by-email、要与commands.cfg命令配置文件里的相对应6)、linux.cfg主机配置文件#====================linux server=====================

check_command check_http
}check_command监控命令有check-host-alive、check_nrpe!check_disk1、check_nrpe!check_load、check_nrpe!check_total_procs、check_nrpe!check_swap等9)、w-services.cfg配置文件define service{

}# 如果要监控c 盘，check_nt!USEDDISKSPACE!-l c -w 80 -c 90 这里的c表示是c盘
check_command命令有check_nt!UPTIME、check_nt!MEMUSE!-w 80 -c 90、(-w 80 -c 90)为当内存使用到80%为warning警告，内存使用到90%为critical紧急，check_nt!USEDDISKSPACE!-l c -w 80 -c 90、check_nt!PROCSTATE!-d SHOWALL -l Explorer.exe等。10)、linux 客户端的安装配置与启动 tar zxvf nrpe-2.8.1.tar.gz
cd nrpe-2.8.1
./configure –prefix=/usr/local/nrpe
make
make install 10.1)、添加nagios用户组，并设置权限root@client#useradd nagios -s /sbin/nologinchown -R nagios.nagios /usr/local/nrpe10.2）、需要把nagios监控服务器里的/usr/local/nagios/libexec下面的5个文件cp到 /usr/local/nrpe/libexec目录下cp /usr/local/nrpe/libexec/check_nrpe /usr/local/nagios/libexec
cp /usr/local/nagios/libexec/check_disk /usr/local/nrpe/libexec
cp /usr/local/nagios/libexec/check_load /usr/local/nrpe/libexec
cp /usr/local/nagios/libexec/check_ping /usr/local/nrpe/libexec
cp /usr/local/nagios/libexec/check_procs /usr/local/nrpe/libexec 10.3）、配置nrpe.cfg文件mkdir /usr/local/nrpe/etc 创建目录复制nrpe解压目录下的nrpe.cfg文件以 /usr/local/nrpe/etc目录下cp /root/nrpe/nrpe.cfg /usr/local/nrpe/etc修改nrpe.cfg文件server_port=5666 #端口
server_address=192.168.1.56 #服务器IP
allowed_hosts=127.0.0.1,192.168.1.56 #充许nagios服务器IP访问 10.4)启动nrpe服务 10.4.1)、以独立守护进程启动nrpe服务/usr/local/nrpe/bin/nrpe –c /usr/local/nrpe/etc/nrpe.cfg -d 10.4.2)、检测nrpe服务是否正常启动[root@nagios nrpe]# netstat -nltp | grep nrpe
tcp 0 0 192.168.1.56:5666 0.0.0.0:* LISTEN 2233/nrpe能查看到5666这端口，说明nrpe启动正常11)、配置windows主机的nrpe服务修改c:\Program Files\NSClient++\NSC.ini文件FileLogger.dll
CheckSystem.dll
CheckDisk.dll
NSClientListener.dll
NRPEListener.dll
SysTray.dll
CheckEventLog.dll
CheckHelpers.dll
CheckWMI.dll#把前面的;分给去掉allowed_hosts=127.0.0.1/32,192.168.1.56 #添加nagios监控服务器的IP，充许nagios服务器访问打开nsclient++ 服务，选择属性---登陆---本地系统账户---(选择)充许服务与桌面交互,重启nsclient++服务net stop nsclient
net start nsclient五、启动nagios监控服务器1）、检查配置/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfgChecking misc settings...Total Warnings: 0
Total Errors: 0Things look okay - No serious problems were detected during the pre-flight check
2)、启动nagios服务/usr/local/nagios/bin/nagios -d /usr/local/nagios/etc/nagios.cfg/etc/init.d/nagios restart #重新启动nagios服务3)、nagios监控页面如下 [url]http://localhost/nagios[/url]
