Nagios 4.0.1版本安裝適用于RHEL/Centos 5.x/6.x 或者Fedora 17/18/19(一)

發布時間：2020-07-13 07:43:25 來源：網絡閱讀：450 作者：老K8 欄目：移動開發

我的環境如下：

Centos-6.2

Nagios 4.0.1

Nagios Plugin 1.5

Nagios是一個非常棒的免費的開源的監控工具，它提供給你一個很全面的監控環境，始終密切監視你的機器或者網絡，不管是在數據中心還是在你自己的一個小實驗室。

步驟1：安裝需要的依賴包

需要安裝Apache、PHP和一些庫像：gcc、glibc、glibc-common、gd、gd-devel、make、net-snmp

[root@taoteng ~]# yum install -y httpd php gcc glibc glibc-common gd gd-devel make net-snmp

步驟2:創建一個nagios用戶和組

創建一個新的nagios用戶和nagcmd組賬戶并設置密碼。

[root@taoteng ~]# useradd nagios
[root@taoteng ~]# groupadd nagcmd

接下來，添加nagios和Apache用戶到nagcmd組。

[root@tecmint]# usermod -G nagcmd nagios

[root@tecmint]# usermod -G nagcmd apache

步驟3：下載Nagios-4.0.1和Nagios-plugin-1.5

在/root目錄下創建一個安裝包以及后續需要下載的安裝包的目錄。

[root@taoteng ~]# mkdir /root/nagios

[root@taoteng ~]# cd /root/nagios

現在來下載最新版本的Nagio-4.0.1和Nagios-plugin-1.5通過wget命令

[root@taoteng nagios]# wget http://prdownloads.sourceforge.net/sourceforge/nagios/nagios-4.0.1.tar.gz

[root@taoteng nagios]# wget https://www.nagios-plugins.org/download/nagios-plugins-1.5.tar.gz

步驟4：提取Nagios和nagios-plugins壓縮包

我們需要通過tar命令來提取下載的壓縮包里面的文件：

[root@taoteng nagios]# tar -zxvf nagios-4.0.1.tar.gz

[root@taoteng nagios]# tar -zxvf nagios-plugins-1.5.tar.gz

緊接著nagios文件夾里面將會出現解壓之后的文件夾

[root@taoteng nagios]# ll

總用量 30668

drwxrwxr-x 18 root root 4096 2月 20 21:22 nagios-4.0.1

-r-xr-xr-x 1 root root 1696847 2月 20 20:58 nagios-4.0.1.tar.gz

drwxr-xr-x 15 nagios nagios 4096 2月 24 00:58 nagios-cn-3.2.3

-r-xr-xr-x 1 root root 9638175 2月 20 20:58 nagios-cn-3.2.3.tar.bz2

drwxr-xr-x 15 200 300 4096 2月 20 22:04 nagios-plugins-1.5

-r-xr-xr-x 1 root root 2428258 2月 20 20:58 nagios-plugins-1.5.tar.gz

配置nagios的核心

現在，首先我們將配置nagios核心，將進入到nagios文件夾里面運行configure命令，如果一切運行順利將會出現下面的界面：

[root@taoteng nagios]# cd nagios-4.0.1

[root@taoteng nagios-4.0.1]# ./configure --with-command-group=nagcmd

輸出示例：

Nagios executable:  nagios        Nagios user/group:  nagios,nagios       Command user/group:  nagios,nagcmd             Event Broker:  yes        Install ${prefix}:  /usr/local/nagios    Install ${includedir}:  /usr/local/nagios/include/nagios                Lock file:  ${prefix}/var/nagios.lock   Check result directory:  ${prefix}/var/spool/checkresults           Init directory:  /etc/rc.d/init.d  Apache conf.d directory:  /etc/httpd/conf.d             Mail program:  /bin/mail                  Host OS:  linux-gnu Web Interface Options: ------------------------                 HTML URL:  http://localhost/nagios/                  CGI URL:  http://localhost/nagios/cgi-bin/ Traceroute (used by WAP):  /bin/tracerouteReview the options above for accuracy.  If they look okay,type 'make all' to compile the main program and CGIs.

隨后配置和編譯所有的的二進制文件，make和make install將會在你的機器上安裝所需的二進制文件然后才能繼續安裝，

[root@taoteng nagios-4.0.1]# make

[root@taoteng nagios-4.0.1]# make install

輸出樣例：

*** Main program, CGIs and HTML files installed ***You can continue with installing Nagios as follows (type 'make'without any arguments for a list of all possible options):  make install-init     - This installs the init script in /etc/rc.d/init.d  make install-commandmode     - This installs and configures permissions on the       directory for holding the external command file  make install-config     - This installs sample config files in /usr/local/nagios/etc

其實從上面的樣例上可以看出下步我們需要的操作步驟，接著執行make install-init去安裝初始化腳本。

[root@taoteng nagios-4.0.1]# make install-init

從輸出的命令行上可以看出我們需要安裝外部命令文件(libxce)

[root@taoteng nagios-4.0.1]# make install-commandmode

接下來安裝nagios示例文件，運行下面的命令：

[root@taoteng nagios-4.0.1]# make install-config

輸出示例：

/usr/bin/install -c -m 775 -o nagios -g nagios -d /usr/local/nagios/etc/usr/bin/install -c -m 775 -o nagios -g nagios -d /usr/local/nagios/etc/objects/usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/nagios.cfg /usr/local/nagios/etc/nagios.cfg/usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/cgi.cfg /usr/local/nagios/etc/cgi.cfg/usr/bin/install -c -b -m 660 -o nagios -g nagios sample-config/resource.cfg /usr/local/nagios/etc/resource.cfg/usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/template-object/templates.cfg /usr/local/nagios/etc/objects/templates.cfg/usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/template-object/commands.cfg /usr/local/nagios/etc/objects/commands.cfg/usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/template-object/contacts.cfg /usr/local/nagios/etc/objects/contacts.cfg/usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/template-object/timeperiods.cfg /usr/local/nagios/etc/objects/timeperiods.cfg/usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/template-object/localhost.cfg /usr/local/nagios/etc/objects/localhost.cfg/usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/template-object/windows.cfg /usr/local/nagios/etc/objects/windows.cfg/usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/template-object/printer.cfg /usr/local/nagios/etc/objects/printer.cfg/usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/template-object/switch.cfg /usr/local/nagios/etc/objects/switch.cfg*** Config files installed ***Remember, these are *SAMPLE* config files.  You'll need to readthe documentation for more information on how to actually defineservices, hosts, etc. to fit your particular needs.

步驟5：自定義nagios配置文件

打開“contacts.cfg”文件編輯當出現報警狀態時候的nagios管理員的電子郵箱

[root@taoteng nagios-4.0.1]# vi /usr/local/nagios/etc/objects/contacts.cfg

輸出樣例：

###############################################################################

# CONTACTS

###############################################################################

# Just one contact defined by default - the Nagios admin (that's you)

# This contact definition inherits a lot of default values from the 'generic-contact'

# template which is defined elsewhere.

define contact{

contact_name nagiosadmin ; Short name of user

use generic-contact ; Inherit default values from generic-contact template (defined above)

alias Nagios Admin ; Full name of user

email xiantao412@sina.com ; <<***** CHANGE THIS TO YOUR EMAIL ADDRESS ******

}

步驟6：安裝和配置Nagios的web接口

到目前為止，我們已經完成了所有的配置，接下來將用下面的命令來配置Nagios的web接口。

下面的命令將配置web接口并同時創建一個“nagiosadmin”管理用戶。

[root@taoteng nagios-4.0.1]# make install-webconf

接下來的這步將會創建一個密碼為“nagiosadmin”記住這個密碼，因為待會兒在瀏覽器中登錄的時候將會用到這個密碼。

[root@taoteng nagios-4.0.1]# htpasswd -s -c /usr/local/nagios/etc/htpasswd.users nagiosadmin
New password:
Re-type new password:
Adding password for user nagiosadmin

重啟Apache服務使新的配置生效。

[root@taoteng nagios-4.0.1]# service httpd restart (On RedHat/CentOS)

[root@taoteng nagios-4.0.1]# systemctl start httpd.service (On Fedora)

步驟7：編譯和安裝nagios插件。

這兒已經下載了nagios插件在/root/nagios目錄下面，直接進去編譯和安裝即可：

[root@taoteng nagios]# tar -zxvf nagios-plugins-1.5

[root@taoteng nagios]# ./configure --with-nagios-user=nagios --with-nagios-group=nagios

[root@taoteng nagios]# make

[root@taoteng nagios]# make install

步驟8：驗證nagios配置文件的是否有錯誤（這就是nagios其中的一個很不錯的地方，可以很清晰的告訴你是否有錯誤）如果沒有什么錯誤就輸出下面的語句：

[root@taoteng nagios]# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfgs

輸出示例：

Total Warnings: 0

Total Errors: 0

Things look okay - No serious problems were detected during the pre-flight check

步驟9：讓Nagios服務隨計算機開機啟動

為了是Nagios和httpd在重啟之后工作，我們需要把這兩個服務chkconfig一下：

[root@taoteng ~]# chkconfig --add nagios

[root@taoteng ~]#chkconfig --level 35 nagios on

[root@taoteng ~]#chkconfig --add httpd

[root@taoteng ~]#chkconfig --level 35 httpd on

重啟Nagios使更改生效！

[root@taoten ~]#service nagios restart

步驟10：通過瀏覽器來登錄到Nagios

我們的Nagios已經可以開始工作了，瀏覽器中輸入http://192.168.162.153/nagios;輸入“nagiosadmin”然后輸入密碼就okay了！
