Centos6.3搭建cacti&nagios

在CentOS6.3上搭建nagios+cacti+ntop+pnp

CentOS版本： centos-x64 2.6.32-279.el6.x86_64 

nagios版本：Nagios  Core 3.4.2

Cacti版本： cacti-0.8.8a

Ntop：ntop-5.0.1

pnp：pnp4nagios-0.6.19

一、配置yum, 更换为163的源

 

1. 首先备份/etc/yum.repos.d/CentOS-Base.repo

         #mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

 

2. 下载对应版本repo文件, 放入/etc/yum.repos.d/(操作前请做好相应备份)

         #http://mirrors.163.com/.help/CentOS6-Base-163.repo

 

3. 修改repo文件名称

         #mv /etc/yum.repos.d/CentOS6-Base-163.repo /etc/yum.repos.d/CentOS-Base.repo       

 

4. 运行yum makecache生成缓存

 

5. 安装rpmforge

         #rpm -ivh rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm

二、安装包及相关软件

1. 每个人机器的环境不一样，我是用最小安装模式安装的centos，需要安装以上的包，如果还安装过程中提示缺少依赖包，请自行安装吧。

yum install httpd -y

yum install php php-mysql php-snmp php-gd -y

yum install mysql mysql-server mysql-devel -y

yum install net-snmp-utils -y

yum install rrdtool* -y

yum install gcc* -y

yum install gd gd-devel -y

yum install glibc* -y

yum install make.x86_64 automake -y

yum install openssl* -y

yum install perl-devel -y

yum install GeoIP GeoIP-devel -y

yum install ettercap  -y

yum install libpcap libpcap-devel -y

yum install wget  -y

yum install automake* -y

yum install libtool -y

yum install subversion -y

yum install libdbi libdbi-devel -y

yum install libdbi-dbd-mysql –y

2. 配置apache

  #vi/etc/httpd/conf/httpd.conf，确保有“LoadModule status_module modules/mod_status.so”这行并没有被注释，标示已经支持检测模块，然后启动apache:

         #servicehttpd start

    #chkconfig --level 35 httpd on  开机启动

 

3. 配置php

         #vi/var/www/html/index.php

         <?php

                   phpinfo();

         ?>

    访问http://localhost，验证php能够正常工作

 

4. 配置mysql

         #servicemysqld start    启动mysql

         #chkconfig--level 35 mysqld on    设置mysql开机启动

         #mysqladmin-u root password 'password'    设置root账号登陆密码

        

    #mysql-u root -p  使用root账号登陆

         mysql>create database cactidb;             创建数据库cactidb，并创建管理账号cactier

         mysql>GRANT all Privileges ON cactidb.* TO cactier@localhost IDENTIFIED BY 'password';        

         mysql>GRANT all Privileges ON cactidb.* TO [email protected] IDENTIFIED BY 'password';

         mysql>flush privileges;                               更新权限设置

 

         创建mysql.php验证mysql数据库连接

         <?php

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

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

                   else echo "OK!";

         ?>

         页面显示OK!表示连接正常。

 

5. 配置SNMP

    #vi/etc/snmp/snmpd.conf   编辑SNMP的配置文件，其中修改一下几行

         # First, map the community name "public"into a "security name"

         #      sec.name  source          community

        41 com2sec notConfigUser  default       public#默认的密码为“public”, 可以改为需要的密码

        62 access  notConfigGroup ""      any       noauth    exact  all none none

       85 view all    included  .1                               80

        #service snmpd start      启动SNMP服务

       #chkconfig--level 35 snmpd on        设置snmp服务开机启动

三、安装nagios

1. 设置nagios用户和组

         #htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin

        

         vi/etc/httpd/conf/httpd.conf

         添加：

         #nagios default settings

            Include /etc/httpd/conf/nagios.conf

         #service httpd restart

         访问http://IP/nagios

 

3. 安装nagios-plugins
