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
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
