vim /etc/nagios/objects/commands.cfg --下面一段默認就有，不需要加，直接改一下 define command{ command_name check_ftp command_line $USER1$/check_ftp -H $HOSTADDRESS$ -w $ARG1$ -c $ARG2$ } # vim /etc/nagios/objects/localhost.cfg --加上下面一段 define service{ use local-service host_name localhost service_description FTP check_command check_ftp!1!3 } #

systemctl restart nagios ============================================================================================= nagios server －－－－》 nagios client 10.1.1.2 10.1.1.3 我們把監控的服務分為公共和私有 公共(public)：如ssh,http,ftp,mysql等。監控本地或遠程的公共服務，都可以直接配置 私有(private)：如load,users,disk usage等。監控本地私有服務直接配置就好，監控遠程私有服務，需要服務和被監控端安裝nrpe 例：監控遠程服務器的普通服務（公共服務）。如ssh,http,ftp，mysql等 如：我的被監控端IP為10.1.1.3 1.在nagios服務器的主配置文件裏加上10.1.1.3的主機配置文件 # vim /etc/nagios/nagios.cfg cfg_file=/etc/nagios/objects/10.1.1.3.cfg 2，創建這個10.1.1.3.cfg # vim /etc/nagios/objects/10.1.1.3.cfg define host{ use linux-server host_name 10.1.1.3 --主機名，最好/etc/hosts裏對應好IP，我這裏沒有做，就直接寫IP alias 10.1.1.3 --顯示到web上的名字 address 10.1.1.3 --實際被監控主機IP } define hostgroup{ hostgroup_name remote linux-servers --這裏我定義了一個新組，不能和localhost.cfg裏的組同名，會沖突 alias remote Linux Servers members 10.1.1.3 } --下面是公共服務，這裏我只寫了四個，你可以自行增加 define service{ use local-service host_name 10.1.1.3 service_description PING check_command check_ping!100.0,20%!500.0,60% } define service{ use local-service host_name 10.1.1.3 service_description SSH check_command check_ssh } define service{ use local-service host_name 10.1.1.3 service_description HTTP check_command check_http } define service{ use local-service host_name 10.1.1.3 service_description FTP check_command check_ftp!1!3 } # nagios -v /etc/nagios/nagios.cfg # systemctl restart nagios ========================================================================== 例:監控遠程的私有服務 10.1.1.2 10.1.1.3 nagios監控端 被監控linux check_disk check_nrpe －－－－－－－－－ check_nrpe check_swap SSL傳輸 check_load等 第一大步:nagios監控端上的操作 1,確認有如下的命令，如果沒有，則yum install nagios-plugins-nrpe /usr/lib64/nagios/plugins/check_nrpe 2，增加check_nrpe命令到commands.conf文件裏 # vim /etc/nagios/objects/commands.cfg define command{ command_name check_nrpe command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$ } --c參數後接command， 也就說check_nrpe可以調用別的check命令 3，在nagios服務器上對10.1.1.3的配置文件增加遠程私有服務 # vim /etc/nagios/objects/10.1.1.3.cfg define service{ use local-service host_name 10.1.1.3 service_description Current Users check_command check_nrpe!check_remote_users } --check_remote_users就是check_nrpe的C參數要調用的命令，此命令在nagios服務器上的commands.cfg裏是不存在，它會在後面的步驟中加到被監控端 # systemctl restart nagios 4,用下面的命令做測試，但現在是會報對方5666端口拒絕(因為被監控端還沒有安裝配置) # /usr/lib64/nagios/plugins/check_nrpe -H 10.1.1.3 -c check_remote_users connect to address 10.1.1.3 port 5666: Connection refused connect to host 10.1.1.3 port 5666: Connection refused 第二大步:nagios被監控端上的操作 1,安裝nrpe和其它監控命令包(需要本地,centos163,epel源) # yum install nrpe nagios-plugins-users 2,修改nrpe主配置文件 # vim /etc/nagios/nrpe.cfg allowed_hosts=10.1.1.2 --把默認的127.0.0.1改成nagios服務器的ip command[check_remote_users]=/usr/lib64/nagios/plugins/check_users -w 5 -c 10 --修改或增加這一行，主要是定義一個叫check_remote_users的命令（和服務器那邊的配置對應) 3,啟動服務，並檢查5666端口是否開啟 # systemctl restart nrpe # systemctl status nrpe # systemctl enable nrpe # lsof -i:5666 第三大步:回到nagios服務器端測試 再次使用下面的命令，就可以監控到遠程的實際登錄用戶數了 # /usr/lib64/nagios/plugins/check_nrpe -H 10.1.1.3 -c check_remote_users USERS WARNING - 9 users currently logged in |users=9;5;10;0 最後，清firefox緩存，在firefox查看遠程監控也正確了 ============================================================================= 練習:監控遠程/分區，/boot分區,swap,cpu load等 ============================================================================= 郵件報警驗證: 1,確認你至少有一個service為crital狀態 2,保證nagios服務器能上公網，還有確認有mail命令了 3,# vim /etc/nagios/objects/contacts.cfg email linuxdaniel@126.com --改成你的一個公網測試郵箱 4,# systemctl restart nagios 如果你想做成免費手機短信通知，可以使用類似139郵箱這種(有郵件到達就短信通知的功能)的郵箱 現在有智能手機就方便多了，直接報警郵件發給外部一個郵箱，然後在你的手機上下載對應郵箱的app軟件就ok了 現在nagios官方直接都有手機客戶端管理軟件 ============================================================================= nagios圖表插件一: nagiosgraph-1.4.4.tar.gz --此軟件包最後的版本是2011年出的，目前在centos7測試過不兼容 以下這份文檔是在rhel6.5上成功的文件（僅做參考) tar xf nagiosgraph-1.4.4.tar.gz -C /usr/src cd /usr/src/nagiosgraph-1.4.4 [root@li nagiosgraph-1.4.4]# ./install.pl --check-prereq checking required PERL modules Carp...1.11 CGI...3.51 Data::Dumper...2.124 File::Basename...2.77 File::Find...1.14 MIME::Base64...3.08 POSIX...1.17 RRDs... ***FAIL*** --沒有rrd,就算你在rhel6上yum install *rrd* 再來測試也是fail Time::HiRes...1.9721 checking optional PERL modules GD...fail --沒有gd,yum install *gd* 也不能搞定 checking nagios installation found nagios at /usr/local/nagios/bin/nagios checking web server installation found apache at /usr/sbin/httpd 安裝gd tar xf libgd-2.1.0.tar.gz -C /usr/src/ cd /usr/src/libgd-2.1.0/ ./configure ;make ;make install echo /usr/local/lib >> /etc/ld.so.conf ldconfig tar xf GD-2.56.tar.gz -C /usr/src/ cd /usr/src/GD-2.56/ perl Build.PL ./Build ./Build install ldconfig 安裝rrdtool #

rpm -qa |grep pnp4 pnp4nagios-0.6.25-1.el7.x86_64 # rpm -e --nodeps pnp4nagios-0.6.25-1.el7.x86_64 warning: /etc/httpd/conf.d/pnp4nagios.conf saved as /etc/httpd/conf.d/pnp4nagios.conf.rpmsave 第二步:解壓源碼版pnp4nagios(軟件包我共享在筆記目錄/program/nagios_soft/下) # tar xf pnp4nagios-0.6.25.tar.gz -C /usr/src/ # cd /usr/src/pnp4nagios-head/ # ./configure --直接configure，統計信息如下 General Options: ------------------------- ------------------- Nagios user/group: nagios nagios Install directory: /usr/local/pnp4nagios HTML Dir: /usr/local/pnp4nagios/share Config Dir: /usr/local/pnp4nagios/etc Location of rrdtool binary: /usr/bin/rrdtool Version 1.4.8 RRDs Perl Modules: FOUND (Version 1.4008) RRD Files stored in: /usr/local/pnp4nagios/var/perfdata process_perfdata.pl Logfile: /usr/local/pnp4nagios/var/perfdata.log Perfdata files (NPCD) stored in: /usr/local/pnp4nagios/var/spool Web Interface Options: ------------------------- ------------------- HTML URL: http://localhost/pnp4nagios Apache Config File: /etc/httpd/conf.d/pnp4nagios.conf #

vim /etc/nagios/objects/commands.cfg define command{ command_name process-service-perfdata-file command_line /bin/mv /usr/local/pnp4nagios/var/service-perfdata /usr/local/pnp4nagios/var/spool/service-perfdata.$TIMET$ } define command{ command_name process-host-perfdata-file command_line /bin/mv /usr/local/pnp4nagios/var/host-perfdata /usr/local/pnp4nagios/var/spool/host-perfdata.$TIMET$ } 第五步:啟動npcd(我們現在使用的是bulk模式和npcd,一共五種模式，具體參考官檔說明) # systemctl start npcd # chkconfig npcd on 第六步:定義模版，在templates.cfg子配置文件裏最後空白地方復制粘貼下面的一段 # vim /etc/nagios/objects/templates.cfg define host { name hosts-pnp register 0 action_url /pnp4nagios/graph?host=$HOSTNAME$&srv=_HOST_ } define service { name service-pnp register 0 action_url /pnp4nagios/graph?host=$HOSTNAME$&srv=$SERVICEDESC$ } 第七步:apache的子配置文件修改（因為這個源碼版對應的語法為apache2.2，而我們centos7.3上用的是apache2.4，所以需要改一下；還有就是我們的nagios使用的是rpm版，所以驗證文件路徑也改一下) # vim /etc/httpd/conf.d/pnp4nagios.conf Require all granted --把Order allow,deny\nAllow from all這兩行刪除，換成這句 AuthUserFile /etc/nagios/passwd --驗證文件路徑也改成這個 # systemctl restart httpd # systemctl enable httpd 第八步:把所有需要加圖表功能的hosts和services加上圖表需要的templates(hosts-pnp和service-php) # vim /etc/nagios/objects/localhost.cfg # vim /etc/nagios/objects/10.1.1.3.cfg --這兩個配置裏的hosts和services都可以加，效果如下示例: define host{ use linux-server,hosts-pnp --如這裏加上hosts-pnp模版 host_name localhost alias localhost address 127.0.0.1 } define service{ use local-service,service-pnp --如這裏加上service-pnp模版 service_description PING check_command check_ping!100.0,20%!500.0,60% } # nagios -v /etc/nagios/nagios.cfg # systemctl restart nagios 第九步:使用firefox訪問測試 訪問後，加了圖表模版的hosts或services會有一個明顯的圖表圖標，點進去，第一次會提示刪除下面文件，刪除後再點進去就ok了 # rm -rf /usr/local/pnp4nagios/share/install.php
