catci的安装

 

环境说明：

操作系统：CentOS6.5_x86_64

mysql：5.17

cacti版本：cacti-0.8.8a

NET-SNMP版本:5.5

cacti:cacti-0.8.8c.tar.gz

 

 

1.安装以下组件或服务,使其开机启动

yum install httpd php php-mysql php-snmpmysql mysql-server net-snmp net-snmp-utils php-gd vixie-cron

yum install rrdtool --nogpgcheck

 

httpd:apache服务,提供web服务

php:php模块,支持动态网页

mysql:mysql服务,存储模板,用户等相关信息。

net-snmp:snmp服务,用来抓取被监控机的数据

rrdtool:存储数据

 

设置以下服务为开机启动

chkconfig mysqld on

chkconfig snmpd on

chkconfig httpd on

 

2.配置(apache配置,apache和php关联)

 

apache 的配置文件

/etc/httpd/conf/httpd.conf

DocumentRoot "/var/www/html"  #  找到数据目录

 

关联php模块

修改DirectoryIndex index.html 为DirectoryIndexindex.html index.php

并添加AddType application/x-httpd-php .php

 

测试php和apache关联是否成功关联

创建测试php页面test.php，并存放在网站主目录下，

<?php

phpinfo();

?>

 

在浏览器中输出http://ip/test.php 如果没有报错就表示关联成功

 

apache和php关联参考

3.安装cacti

官网下载:wget http://www.cacti.net/downloads/cacti-0.8.8c.tar.gz

 

解压之后复制文件,目录到apache 根目录

mkdir /var/www/html/cacti

 

cd /home/software/cacti-0.8.8c

 

cp -rf  *  /var/www/html/cacti/

 

创建数据库：

mysql> create database cacti defaultcharacter set utf8;

 

导入数据cacti数据：

mysql> mysql  -uroot -ptest@123 cacti <  /var/www/html/cacti/cacti.sql

mysql> GRANT ALL ON cacti.* TOcacti@localhost IDENTIFIED BY 'cacti';

mysql> flush privileges;

 

修改配置文件：

vi  /var/www/html/cacti/include/config.php

$database_type = "mysql";

$database_default = "cacti";

$database_hostname = "localhost";

$database_username = "cacti";

$database_password = "cacti";

$database_port = "3306";

 

/var/www/html/cacti/include/global.php

$database_type = "mysql";

$database_default = "cacti";

$database_hostname = "localhost";

$database_username = "cacti";

$database_password = "cacti";

$database_port = "3306";

 

useradd cacti  :添加cacti 用户

添加权限:

cd /var/www/html/cacti 

chown -R cacti rra/ log/

 

4.配置snmp使可以监控本机(被监控机上安装)

yum -y install net-snmp net-snmp-utils

 

编辑snmp配置文件/etc/snmp/snmp.conf

 

修改：

com2sec notConfigUser  default      public

改为：

com2sec notConfigUser  监控主机的ip       public

 

修改：

access notConfigGroup ""     any       noauth    exact systemview none none

改为：

access notConfigGroup ""     any       noauth    exact all none none

 

去掉这句的注释

#view all   included  .1                               80

 

重启snmp服务并测试

service snmpd restart

 

5.安装spine:提升监控效率

http://www.cacti.net/downloads/spine/

 

#tar xf cacti-spine-0.8.8a.tar.gz

# cd cacti-spine-0.8.8a

#./configure --prefix=/usr/local/cacti-spine

configure: error: Cannot find SNMPheaders.  Use --with-snmp= to specifynon-default path.

 

#yum -y net-snmp-devel

#./configure--prefix=/usr/local/cacti-spine

 

在安装cacti-spine过程中，configure编译时出现如下错误提示：

configure: error: Cannot find MySQLheaders.  Use --with-mysql= to specifynon-default path.

原来是找不到mysql头，原来是mysql-devel没有安装，于是先安装mysq-devel:

#yum -y mysq-devel

如果出现无法注册X86-64错误，升级gcc

#yum -y gcc

 

#Make && make install

#cd /usr/local/cacti-spine/etc/

#cp spine.conf.dist spine.conf

#vim spine.conf

DB_Host         localhost

DB_Database     cacti

DB_User         cacti

DB_Pass         cacti

DB_Port         3306

DB_PreG         0

#/usr/local/cacti-spine/bin/spine --conf=/usr/local/cacti-spine/etc/spine.conf 测试spine安装是否正确，输出下面信息表示安装成功

 

6.cacti故障排查：

检测被监控端是否可以与监控机通信。

snmpwalk -c public -v 2c 监控主机ipIF-MIB::ifHCInOctets

snmpwalk -v 2c -c public 监控主机ip if

检查rrd文件是否问nan：

rrdtool fetch fxd-mdl11_traffic_in_365.rrdAVERAGE
