npc-2.0.4.tar.gz  json-1.2.1.tgz  PDO_MYSQL-1.0.2.tgz

一．設置lamp環境

編譯安裝httpd

Shell>tar zxvf httpd-2.4.1.tar.gz

Shell>cd httpd-2.4.1

Shell>./configure  --prefix=/usr/local/apache --enable-so

Shell>make && make install

編譯安裝msyql

Shell>tar zxvf mysql-5.3.25.tar.gz

Shell>cd mysql-5.3.25

Shell>./configure --prefix=/usr/local/mysql  --enable-thread-safe-client

Shell>make && make install

Shell>groupadd mysql

Shell>useradd mysql -g mysql

Shell>chown -r mysql.mysql /var/lib/mysql

Shell>/usr/local/mysql/bin/mysql_install_db    ##初始化數據庫##

Shell>cp support-files/my-medium.cnf /etc/my.cnf

Shell>/usr/local/mysql/bin/mysqld_safe  --defaults-file=/etc/my.cnf  --user=root &  

     ##啟動mysql##

Shell>/usr/local/msyql/bin/mysqldadmin -uroot -p 123456     #修改mysql登陸密碼##

Shell>ps -ef |grep mysqld    ##查看mysq進程##

編譯安裝

Shell>tar zxvf php-5.3.25.tar.gz

Shell>cd php-5.3.25

Shell>./confiugre --prefix=/usr/local/php  --with--mysql=/usr/local/mysql  

     --with-apxs2=/usr/local/apache/bin/apxs  --enable-sockets

     --with-config-file-path=/usr/local/php/etc  ##修改php.ini的存放位置##

Shell>make &&  make install

Shell>cp  php.ini-production  /etc/php.ini

安裝pdo_mysql擴展模塊

Shell>tar zxvf    PDO_MYSQL-1.0.2.tgz

Shell>cd   PDO_MYSQL-1.0.2

Shell>/usr/local/php/bin/phpize

Shell>make && make install

Shell>vim  /usr/local/php/etc/php.ini

     extension_dir = "/usr/local/php/lib/php/extensions/no-debug-zts-20090626/"

     extension = pdo_mysql.so

重啟apahce  查看是否已加載  php  -m |grep pdo-mysql

二、Apache php整合

打開Apache配置文件httpd.conf

添加PHPIniDir "/etc/php.ini"

跳轉到373后添加

AddType application/x-httpd-php .php

AddType application/x-httpd-php-source .phps

跳轉到246行添加 index.php

保存退出重啟apache  

Shell>/usr/local/apache/bin/apachectl start  

測試apache，php是否整合

Shell>vim /usr/local/apache/htdocs/text.php

<?php

Phpinfo;

?>

打開瀏覽器輸入http://ip/test.php，輸出php信息說明配置成功

測試php mysql整合

Shell>vim /usr/local/apache/htdocs/test.php

<?php

$link=mysql_connect("localhost","root","123456");

if(!$link) echo "FAILD!";

else echo "OK!";

?>

保存退出打開瀏覽器http://ip/test.php  輸出ok說明配置成功

三、安裝nagios

Shell>useradd -s /sbin/nologin nagios

Shell>mkdir -p /usr/local/nagios

Shell>chown -R nagios.nagios /usr/local/nagios

Shell>usermod  -G  nagios  -a  apache   ##將apache用戶加入到nagios組中

Shell>tar zxvf nagios-3.2.0.tar.gz

Shell>cd nagios-3.2.0

Shell>./configure --prefix=/usr/local/nagios

Shell>make all

Shell>make install

Shell>make install-init

Shell>make install-commandmode

Shell>make install-config

安裝nagios插件

Shell>tar zxvf nagios-plugins-1.4.16.tar.gz

Shell>cd nagios-plugins-1.4.16

Shell>./configure --prefix=/usr/local/nagios

Shell>make && make install

打開apache配置文件httpd.conf 在末尾添加以后代碼：

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

   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>

創建nagios登陸用戶

Shell>/usr/local/apache/bin/htpasswd -c /usr/local/nagios/etc/htpasswd admin     ##輸入登陸密碼

修改nagios目錄下cgi.cfg

Shell>vim /usr/local/nagios/etc/cgi.cfg

authorized_for_system_information=admin       #多個用戶用逗號分隔

authorized_for_configuration_information=admin

authorized_for_system_commands=admin

authorized_for_all_services=admin

authorized_for_all_hosts=admin

authorized_for_all_service_commands=admin

authorized_for_all_host_commands=admin

修改nagios目錄下nagios.cfg

command_check_interval=10s    ##檢查時間間隔

check_external_commands=1    ##允許web界面下重啟、關閉nagios進程等

檢查下nagios配置文件是否正確

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

修改apache 運行的用戶

Shell>vim /usr/local/apache/conf/httpd.conf

    User  apache

    Group  apache

啟動nagios

Shell>/usr/local/nagios/bin/nagios -d  /usr/local/nagios/etc/nagios.cfg

啟動apache

Shell>/usr/local/apache/bin/httpd -k start

打開瀏覽器輸入http://ip/nagios就可以看到nagios的主界面

四、安裝nrpe

被監控機上安裝

Shell>groupadd nagios

Shell>useradd -g nagios -d  /usr/local/nagios  -s  /sbin/nologin  nagios

Shell>tar zxvf  nagios-plugins-1.4.16.tar.gz

Shell>tar zxvf nrpe-2.12.tar.gz

Shell>cd nrpe-2.12

Shell>./configure

Shell>make all

Shell>make instlal-plugin

Shell>make install-daemon

Shell> make install-daemon-config

Shell>chown  -R  nagios.nagios  /usr/local/nagios

配置nrpe

Shell>vim /usr/local/nagios/etc/nrpe.cfg

allowed_hosts=127.0.0.1,監控機ip

Shell>echo “nrpe:監控機ip” >>/etc/host.allow

啟動nrpe

Shell>/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d

Shell>echo “/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d “ >>/etc/rc.local  

    ## 設置開機啟動nrpe

檢查nrpe是否正常

Shell>netstat -atnlp |grep 5666

Shell>/usr/local/nagios/libexec/check_nrpe -H localhost

    NRPE v2.12                      ##說明nrpe啟動成功

監控機上安裝

Shell>tar zxvf  nrpe-2.12.tar.gz

Shell>cd nrpe-2.12

Shell>./configure --prefix=/usr/local/nagios

Shell>make

Shell>make install-plugin

測試是否可以連接被監控機

Shell>/usr/local/nagios/libexec/check_nrpe  -H  被監控機ip

     NRPE v2.12                    ##說明可以和被監控機通信

Shell>passwd  cactier

Shell>crontab -u cactier -e

*/1 * * * * *  /usr/bin/php /var/www/html/cacti/poller.php >/dev/null 2>&1  

登陸cacti

打開瀏覽器輸入http://ip/cacti   ---->設置

注意第一次登陸cacti默認用戶名和密碼為admin，登陸后要修改密碼
