Nagios伺服器端安裝部署詳解(1)

如下： http://sourceforge.net/projects/nagios/files/

具體詳細：http://prdownloads.sourceforge.net/sourceforge/nagios/nagios-4.0.6.tar.gz

1 開始下載：
 wget http://sourceforge.net/projects/nagios/files/nagios-4.x/nagios-4.0.6/nagios-4.0.6.tar.gz/download?use_mirror=jaist
如所示，下載free版本的。

安裝前準備工作，安裝一些lib包：

[root@cache-2 root]# yum -y install httpd gcc glibc glibc-common

# yum install -y gcc glibc glibc-common gd gd-devel xinetd openssl-devel

2 進行selinux設定，或者關閉selinux

 查看SELinux狀態：

 (1)/usr/sbin/sestatus -v      ##如果SELinux status參數為enabled即為開啟狀態

         SELinux status:                 enabled

 (2)getenforce                 ##也可以用這個命令檢查

 關閉SELinux：

 (3)臨時關閉（不用重啟機器）：

         setenforce 0                  ##設定SELinux 成為permissive模式

                              ##setenforce 1 設定SELinux 成為enforcing模式

 (4)修改設定檔需要重啟機器：

         修改/etc/selinux/config 檔案

         將SELINUX=enforcing改為SELINUX=disabled

         重啟機器即可

3 開始準備nagios安裝環境

  (1) 添加nagios運行所需要的使用者和組：

  groupadd nagcmd

         useradd -m nagios

         usermod -a -G nagcmd nagios

        

把apache加入到nagcmd組，以便於在通過web Interface操作nagios時能夠具有足夠的許可權：

# usermod -a -G nagcmd apache

4 編譯安裝準備

./configure --with-command-group=nagios --prefix=/opt/app/nagios --enable-embedded-perl --with-httpd-conf=/usr/local/apache2/conf

[root@cache-2 nagios-4.0.6]# ./configure --with-command-group=nagios  --prefix=/opt/app/nagios --enable-embedded-perl  --with-httpd-conf=/usr/local/apache2/confchecking for a BSD-compatible install... /usr/bin/install -cchecking build system type... x86_64-unknown-linux-gnuchecking host system type... x86_64-unknown-linux-gnuchecking for gcc... gccchecking for C compiler default output file name... a.outchecking whether the C compiler works... yeschecking whether we are cross compiling... no.............................

If they look okay,type 'make all' to compile the main program and CGIs.

5 開始make安裝

[root@cache-2 nagios-4.0.6]#

加到啟動項裡面去：

# chkconfig --add nagios

# chkconfig --level 35 nagios on

# chkconfig --list nagios

檢查主機設定檔是否正確：

/var/www/nagios/bin/nagios -v /var/www/nagios/etc/nagios.cfg

5.6 Check安裝是否正確：

5.6.1說明：

切換目錄到安裝路徑（這裡是/usr/local/nagios），看是否存在etc、bin、sbin、share、var 這五個目錄，如果存在則可以表明程式被正確的安裝到系統了。Nagios 各個目錄用途說明如下：

bin    Nagios 可執行程式所在目錄

etc   Nagios 設定檔所在目錄

sbin  Nagios CGI 檔案所在目錄，也就是執行外部命令所需檔案所在的目錄

share        Nagios網頁檔案所在的目錄

libexec      Nagios 外部外掛程式所在目錄

var   Nagios 記錄檔、lock 等檔案所在的目錄

var/archives     Nagios 日誌自動歸檔目錄

var/rw      用來存放外部命令檔案的目錄

5.6.2 check
 cd /usr/local/nagios

5.8 安裝配置apache和php
(1)安裝apache
下載 wget http://archive.apache.org/dist/httpd/httpd-2.4.7.tar.gz

[root@cache-2 ~]# wget http://archive.apache.org/dist/httpd/httpd-2.4.7.tar.gz--2014-05-05 16:15:48--  http://archive.apache.org/dist/httpd/httpd-2.4.7.tar.gz正在解析主機 archive.apache.org... 192.87.106.229, 140.211.11.131, 2001:610:1:80bc:192:87:106:229正在串連 archive.apache.org|192.87.106.229|:80... 已串連。已發出 HTTP 要求，正在等待回應... 200 OK長度：6747087 (6.4M) [application/x-gzip]正在儲存至: “httpd-2.4.7.tar.gz” 1% [=>                                                ..............................................................2014-05-05 16:16:01 (574 KB/s) - 已儲存 “httpd-2.4.7.tar.gz” [6747087/6747087])

開始安裝：
 tar -xvf httpd-2.4.7.tar.gz
 cd httpd-2.4.7
 ./configure --prefix=/usr/local/apache2
make && make install

[root@cache-2 ~]# tar -xvf httpd-2.4.7.tar.gz[root@cache-2 ~]# cd httpd-2.4.7[root@cache-2 httpd-2.4.7]# ./configure --prefix=/usr/local/apache2checking for chosen layout...

Please read the documentation.Google之後，發現可能是gcc版本太低了，可能是apache版本太高，換低點的2.2.23版本吧。wget http://archive.apache.org/dist/httpd/httpd-2.2.23.tar.gztar -xvf  httpd-2.2.23.tar.gzcd httpd-2.2.23./configure --prefix=/usr/local/apache2make && make install

(2) 安裝php版本

wget http://cn2.php.net/distributions/php-5.4.26.tar.gz

tar -xvf php-5.4.26.tar.gz

cd php-5.4.26

./configure --prefix=/usr/local/php --with-apxs2=/usr/local/apache2/bin/apxs

需要重新安裝lib包

yum install libxml2 –y

yum install libxml2-devel –y

 

之後繼續make，成功了：

Make && make install

(3) 配置apache

Apache的設定檔在 /usr/local/apache2/conf/httpd.conf ，vim開啟

將

User daemon

Group daemon

修改成：

User nagios

Group nagios

將

<IfModule dir_module>

　　DirectoryIndex index.html

</IfModule>

修改成：

<IfModule dir_module>

　　DirectoryIndex index.html index.php

    AddType application/x-httpd-php .php

</IfModule>

 

為了安全起見：nagios的web監控頁面需要經過授權才能訪問，這需要增加驗證配置，即在httpd.conf 檔案最後添加如下資訊：

#setting for nagios

ScriptAlias /nagios/cgi-bin "/usr/local/nagios/sbin"

<Directory "/usr/local/nagios/sbin">

     AuthType Basic

     Options ExecCGI

     AllowOverride None

     Order allow,deny

     Allow from all

     AuthName "Nagios Access"

     AuthUserFile /usr/local/nagios/etc/htpasswd  //用於此目錄訪問身分識別驗證的檔案             

     Require valid-user

</Directory>

Alias /nagios "/usr/local/nagios/share"

<Directory "/usr/local/nagios/share">

     AuthType Basic

     Options None

     AllowOverride None

     Order allow,deny

     Allow from all

     AuthName "nagios Access"

     AuthUserFile /usr/local/nagios/etc/htpasswd

     Require valid-user

</Directory>

(4) 建立apache目錄驗證檔案

在上面的配置中，指定了目錄驗證檔案htpasswd，下面要建立這個檔案：

/usr/local/apache2/bin/htpasswd -c /usr/local/nagios/etc/htpasswd david

[root@cache-2 php-5.4.26]#  /usr/local/apache2/bin/htpasswd -c /usr/local/nagios/etc/htpasswd david

New password:

Re-type new password:

Adding password for user david

查看認證檔案的內容：

[root@cache-2 php-5.4.26]#  cat /usr/local/nagios/etc/htpasswd

david:$apr1$Pf9XIJjd$m5hR2vw70MlqwrChgN7zc/

[root@cache-2 php-5.4.26]#

 

啟動apache服務：

/usr/local/apache2/bin/apachectl start

[root@cache-2 php-5.4.26]# /usr/local/apache2/bin/apachectl start

httpd: Could not reliably determine the server's fully qualified domain name, using 10.254.3.41 for ServerName

(98)Address already in use: make_sock: could not bind to address [::]:80

(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80

no listening sockets available, shutting down

Unable to open logs

修改ServerName以及Port

vi /usr/local/apache2/conf/httpd.conf

ServerName 改成 10.xx.3.x1

Listen 80 改成 Listen 81

http://10.xx.3.x1:81/nagios/，可以開啟了，如下所示：
