Nagios+NSClient+nrpe環境搭建

標籤：nagios   nginx   zabbix   nrpe   nsclient   

Nagios是一款開源的免費網路監視工具，能有效監控Windows、Linux和Unix的主機狀態，交換器路由器等網路裝置，印表機等。在系統或服務狀態異常時發出郵件或簡訊警示第一時間通知網站營運人員，在狀態恢複後發出正常的郵件或簡訊通知。

NSClient：Windows 7監控外掛程式

NRPE是監視軟體nagios的一個擴充，它被用於被監控的伺服器上，向nagios監控平台提供該伺服器的一些本地的情況。例如，cpu負載、記憶體使用量、硬碟使用等等。NRPE可以稱為nagios的for linux 用戶端。

1.安裝軟體：

yum install -y gcc*

yum install -y httpd mysql mysql-server mysql-devel php php-mysql glibc glibc-common *gd*

2.添加使用者：

3.編譯安裝nagios：

此次安裝使用的軟體包是 nagios.iso

650) this.width=650;" src="https://s4.51cto.com/wyfs02/M00/99/BC/wKiom1lLpCaiA5aHAACYcIFN4T8892.png" title="2.png" alt="wKiom1lLpCaiA5aHAACYcIFN4T8892.png" />

tar -xvf nagios-3.3.1.tar.gz -C /root/

然後進入nagios目錄下

./configure --with-command-group=nagcmd --enable-event-broker

make all

make install

make install-init

make install-commandmode

make install-config

make install-webconf

4.產生密碼設定檔：

650) this.width=650;" src="https://s1.51cto.com/wyfs02/M00/99/BC/wKioL1lLpCniYZYcAAOOZLVRTG4266.png" title="3.png" alt="wKioL1lLpCniYZYcAAOOZLVRTG4266.png" />

650) this.width=650;" src="https://s2.51cto.com/wyfs02/M01/99/BC/wKiom1lLpCqzspWjAAB0DRr-q6E760.png" title="4.png" alt="wKiom1lLpCqzspWjAAB0DRr-q6E760.png" />

開啟Apache服務

5.瀏覽器查看：

650) this.width=650;" src="https://s2.51cto.com/wyfs02/M01/99/BC/wKioL1lLpCvR0JYTAADurosBLdk088.png" title="5.png" alt="wKioL1lLpCvR0JYTAADurosBLdk088.png" />

6.安裝外掛程式管理器nagios-plugins：

tar -xvf nagios-plugins-1.4.14.tar.gz -C /root/

進入目錄編譯安裝（nagios-plugins-1.4.14）

./configure --with-nagios-user=nagios --with-nagios-group=nagios --with-mysql  --enable-perl-modules

make && make install

650) this.width=650;" src="https://s1.51cto.com/wyfs02/M00/99/BC/wKiom1lLpC2yankEAAA_mH_yYaE415.png" title="7.png" alt="wKiom1lLpC2yankEAAA_mH_yYaE415.png" />

檢查設定檔是否有錯誤：

/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

650) this.width=650;" src="https://s4.51cto.com/wyfs02/M02/99/BC/wKiom1lLpC6RtxFqAAIYObzC2Ws382.png" title="8.png" alt="wKiom1lLpC6RtxFqAAIYObzC2Ws382.png" />

重啟nagios服務

此時再去瀏覽器檢查：

在Linux客戶的上面：

安裝環境支援：

yum install -y gcc* openssl openssl-devel

編譯安裝nagios-plugins

tar -xvf nagios-plugins-1.4.14.tar.gz

需要建立使用者

useradd nagios

./configure --with-nagios-user=nagios --with-nagios-group=nagios

make all

make install

編譯安裝nrpe-2.8.1.tar.gz

./configure --enable-ssl --with-ssl-lib=/usr/lib

安裝nrpe

tar -xvf nrpe-2.8.1.tar.gz -C /root/

./configure --enable-ssl --with-ssl-lib=/usr/lib

make all

make install-plugin

不用啟用daemon和daemon-config
