nagios部署安裝

一．支持PHP的apachehe,和nagios安裝依賴包。

#yum –y install httpd php gd gcc gcc-g++ mysql mysql-devel

 

二.下載安裝包

http://www.nagios.org/download

 

 

三. 安裝

   1．  建用戶和組

[root@localhost~]# groupadd nagios [root@localhost~]# useradd -g nagios -G nagios -m -s /sbin/nologin nagios

 

2.解壓安裝文件

 

[root @localhost ~]# mkdir /usr/src/nagios/ [root @localhost ~]# tar zxvf nagios-3.3.1.tar.gz -C /usr/src/nagios/ [root @localhost ~]# tar zxvf nagios-plugins-1.4.15.tar.gz -C/usr/src/nagios/ [root @localhost ~]# tar zxvf nrpe-2.12.tar.gz -C /usr/src/nagios/

 

3安裝 nagios-3.3.1.tar.gz

[root @localhost nagios]#cd /usr/src/nagios/nagios [root @localhost nagios]# ./configure --prefix=/usr/local/nagios --with-command-group=nagios [root @localhost nagios]# make all [root @localhost nagios]# make install [root @localhost nagios]# make install-init [root @localhost nagios]# make install-commandmode [root @localhost nagios]# make install-config

注意若是報錯：

/usr/bin/install: omitting directory `includes/rss/extlib'

/usr/bin/install: omitting directory `includes/rss/htdocs'

/usr/bin/install: omitting directory `includes/rss/scripts'

make[1]: *** [install] Error 1

make[1]: Leaving directory `/usr/src/nagios/nagios/html'

make: *** [install] Error 2

 

措施：

[root@localhost nagios]# sed -i 's/for file in includes\/rss\/\*\;/for file in includes\/rss\/\*\.\*\;/g' ./html/Makefile

[root@localhost nagios]# sed -i 's/for file in includes\/rss\/extlib\/\*\;/for file in includes\/rss\/extlib\/\*\.\*\;/g' ./html/Makefile

執行這兩句代碼。

從新make install

[root@localhost nagios]# make install

 

 

4.安裝nagios-plugins-1.4.15.tar.gz

[root @localhost nagios]# cd/usr/src/nagios/nagios-plugins-1.4.15/ [root @localhost nagios-plugins-1.4.15]# ./configure --with-nagios-user=nagios--with-nagios-group=nagios --prefix=/usr/local/nagios/ [root @localhost nagios-plugins-1.4.15]#make && make install

 

5.安裝nrpe-2.12.tar.gz

[root @localhost nagios-plugins-1.4.15]# cd /usr/src/nagios/nrpe-2.12/ [root @localhost nrpe-2.12]# ./configure --prefix=/usr/local/nagios/   [root @localhost nrpe-2.12]# make all [root @localhost nrpe-2.12]# make install-plugin

6.設置Apache開機啓動

[root @monitor ~]# vi /etc/rc.d/rc.local #增長以下一行 /usr/local/apache/bin/apachectlstart

 

四．配置WEB訪問

[root @localhost nrpe-2.12]# vi /etc/httpd/conf/httpd.conf #修改apache 運行用戶      User nagios      Group nagios    #支持PHP  添加 index.php  DirectoryIndex index.php index.html index.html.var       #在最後加入nagios web訪問部分     ScriptAlias/nagios/cgi-bin "/usr/local/nagios/sbin/" Alias/nagios "/usr/local/nagios/share/" <Directory "/usr/local/nagios/sbin/">   Options ExecCGI   AllowOverride none   Order allow,deny   Allow from all   AuthName"Nagios Access"  AuthType Basic   AuthUserFile/usr/local/nagios/etc/htpasswd   Require valid-user </Directory> <Directory "/usr/local/nagios/share/">   Options None  AllowOverride none   Order allow,deny   Allow from all   AuthName"Nagios Access"   AuthType Basic   AuthUserFile/usr/local/nagios/etc/htpasswd   Require valid-user </Directory>

配置web訪問用戶密碼

[root@localhostnrpe-2.12]# htpasswd -c /usr/local/nagios/etc/htpasswd nagiosadmin     #密碼輸入 [root @localhost nrpe-2.12]# service httpd start

在瀏覽器輸入http://IP/nagios  出現如圖

          

出現web訪問配置正確.

 

五．配置nagios

說明：服務器分三個組，linuxserver，windowsserver，networkserver（如交換機，路由器）。

  配置實驗說明.

IP	服務器OS	監控服務
192.168.20.194	監控機LINUX	Mysql,squid,ssh,ping
192.168.20.184	LINUX	Mysql,httpd,ssh,ping
192.168.20.187	windows	3389,21,ping
192.168.20.1	switch	ping

   

A． 配置聯繫人

先備份原配置文件

[root @localhost objects]# cd /usr/local/nagios/etc/objects/ [root @localhost objects]# tar zcvf back.tar.gz ./*     [root @localhost objects]# vi contacts.cfg #清空裏面的內容添加下配置                                                 define contact{                         contact_name                    nagiosadmin                         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                         host_notification_commands      notify-host-by-email                         email                           chunjian.feng@jrj.com.cn                         #pager                          13800138000                         }                                                   define contactgroup{                         contactgroup_name       admins                         alias                  Nagios Administrators                         members                 nagiosadmin                         }

 

B． 配置命令文件

[root @localhost objects]# vi commands.cfg 添加下面兩個命令                                       definecommand{                         command_name    check_nrpe                         command_line    $USER1$/check_nrpe-H $HOSTADDRESS$ -c $ARG1$                         }                     definecommand{                         command_name    check_mysql                         command_line    $USER1$/check_mysql-u $ARG1$ -p $ARG2$ -H $HOSTADDRESS$ -P $ARG3$ -d $ARG4$ $ARG5$                         }

 

C.配置templates.cfg

[root @localhost objects]# vi templates.cfg #清空裏面的內容添加下配置                         define host{                         name                    generic-host                         contact_groups          admins                         check_command           check-host-alive                         max_check_attempts      5                         notification_interval   10                         notification_period     24x7                         notification_options    d,u,r                         }                     define service{                         name                    generic-service                         check_period            24x7                         max_check_attempts      4                         normal_check_interval   3                         retry_check_interval    2                         contact_groups          admins                         notification_interval   10                         notification_period     24x7                         notification_options    w,u,c,r                         }

 

D.配置linux服務器組

咱們把只帶的localhost.cfg改成LINUX server的定義文件。

[root @localhost objects]# vi localhost.cfg #清空    define hostgroup{         hostgroup_name  linux-servers         alias          Linux Servers         members         localhost,192.168.20.184            }      define host{          use                     generic-host                                                                                                           host_name               localhost          alias                  localhost          address                 127.0.0.1         } ################localhost server                         define service{                                           host_name               localhost                                           service_description     load average                                           check_command           check_nrpe!check_load                                           use                     generic-service                                           }                                define service{                                           host_name               localhost                                           service_description     total-procs                                           check_command           check_nrpe!check_total_procs                                           use                     generic-service                                           }                              define service{                                           host_name               localhost                                           service_description    freespace                                           check_command           check_nrpe!check_disk                                           use                     generic-service                                           }                              define service{                                              host_name               localhost                                                service_description     mysql                                                check_command          check_mysql!root!123456                                                use                    generic-service                                                }                              define service{                                               use                            generic-service                                                  host_name                       localhost                                            service_description             PING                                           check_command               check_ping!100.0,20%!500.0,60%                                            }                                   define service{                                              use                            generic-service        ;

注:windows 和switch相似的定義。咱們分別用自帶的windows.cfg，switch.cfg文件配置。

E.開啓nagios進程

[root @monitor ~]# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg Checking obsessive compulsive processor commands... Checking misc settings... Total Warnings: 0 Total Errors:   0     [root @monitor ~]# /usr/local/nagios/bin/nagios -d /usr/local/nagios/etc/nagios.cfg [root @monitor ~]#echo "/usr/local/nagios/bin/nagios -d /usr/local/nagios/etc/nagios.cfg" >> /etc/rc.d/rc.local

 

 

 

六.配置linux客戶端

A.創建用戶和安裝客戶端。

[root@LNMP4 ~]# yum install bc Useradd nagios tar-zxvf nagios-plugins-1.4.14.tar.gz cdnagios-plugins-1.4.14 ./configure--with-nagios-user=nagios --with-nagios-group=nagios --prefix=/usr/local/nagios make&&makeinstall   tar-zxvf nrpe-2.12.tar.gz cdnrpe-2.12 ./configure--prefix=/usr/local/nagios makeall makeinstall-plugin makeinstall-daemon makeinstall-daemon-config chown-R nagios.nagios/usr/local/nagios

 

B.配置被監控機

vim/usr/local/pmediasrv/nagios/etc/nrpe.cfg  allowed_hosts=127.0.0.1,192.168.20.194  #監控機的IP和本機IP   command[check_load]=/usr/local/pmediasrv/nagios/libexec/check_load-w 15,10,5 -c 30,25,20 command[check_total_procs]=/usr/local/pmediasrv/nagios/libexec/check_procs-w 150 -c 200 command[check_disk]=/usr/local/nagios/libexec/check_disk-w 20% -c 10%

啓動客戶端進程：

/usr/local/pmediasrv/nagios/bin/nrpe-c/usr/local/pmediasrv/nagios/etc/nrpe.cfg –d

 

七．配置windows 客戶端。

下載客戶端地址：

http://files.nsclient.org/x-0.3.x_STABLE/NSClient%2B%2B-0.3.7-Win32.msi   32位

http://files.nsclient.org/x-0.3.x_STABLE/NSClient%2B%2B-0.3.7-x64.msi      64位

 

下載安裝好。配置，在安裝目錄下編輯NSC.ini

[modules] FileLogger.dll CheckSystem.dll CheckDisk.dll NSClientListener.dll NRPEListener.dll SysTray.dll CheckEventLog.dll CheckHelpers.dll ;CheckWMI.dll ; RemoteConfiguration IS AN EXTREM EARLY IDEA SO DONT USE FOR PRODUCTION ENVIROMNEMTS! ;RemoteConfiguration.dll ; NSCA Agent is anewbeta module use with care! NSCAAgent.dll ; LUA script module used to write your own "check deamon"(sort of) early beta. LUAScript.dll ; Script to check external scripts and/or internal aliases, early beta. CheckExternalScripts.dll ; Check other hosts through NRPE extreme beta and probably a bit dangerous! :) NRPEClient.dll ; Extreamly early beta of a task-schedule checker CheckTaskSched.dll       最後配置 allowed_hosts=127.0.0.1/32,192.168.20.194  容許192.168.20.194 port=12489         監聽端口

注：從新啓動客戶端
