Cacti安装及配置

Cacti简介
Cacti是用php语言实现的一个软件，用snmp服务获取数据，用rrdtool储存和更新数据，当用户需要查看数据的时候用rrdtool生成图表呈现给用户。因此，snmp和rrdtool是cacti的关键。Snmp关系着数据的收集，rrdtool关系着数据存储和图表的生成。
Mysql配合PHP程序存储一些变量数据并对变量数据进行调用，如：主机名、主机ip、snmp团体名、端口号、模板信息等变量。
snmp抓到数据不是存储在mysql中，而是存在rrdtool生成的rrd文件中（在cacti根目录的rra文件夹下）。rrdtool对数据的更新和存储就是对rrd文件的处理。

Cacti怎么用

安装rrdtool

CentOS-5:rpm -ivh http://apt.sw. be/redhat/el5/en/i386/rpmforge/RPMS/rpmforge-release-0.5.2-2.el5.rf.i386.rpmyum install rrdtool -yCentOS-6:rpm -ivh http://apt.sw.be/redhat/el6/en/i386/rpmforge/RPMS/rpmforge-release-0.5.2-2.el6.rf.i686.rpmyum install rrdtool -y

安装配置net-snmp

1、安装net-snmpyum install net-snmp net-snmp-libs net-snmp-utils2、配置net-snmp修改：view systemview included .1.3.6.1.2.1.1为：view systemview included .1.3.6.1.2.13、测试net-snmp# service snmpd start# snmpwalk -v 1 -c public localhost .1.3.6.1.2.1.1.1.0SNMPv2-MIB::sysDescr.0 = STRING: Linux cronos 2.4.28 #2 SMP ven jan 14 14:12:01 CET 2005 i686

安装LAMP

yum install httpd php php-mysql php-snmp php-xml php-gd mysql mysql-serverservice httpd startservice mysqld startmysqladmin -uroot password yourpasswordmysqladmin --user=root --password reload

安装cacti

1、下载cacticd /tmpwget http://www.<cite class="highlight" highlight="true" style="background-image: none; background-position: initial initial; background-repeat: initial initial; ">cacti. net</cite>/downloads/cacti-0.8.8a.tar.gztar xzf cacti-0.8.8a.tar.gzmv cacti-0.8.8a /var/www/html/cacticd /var/www/html/cacti2、创建数据库mysqladmin --user=root -p create cacti3、导入数据库mysql -uroot -p cacti < cacti.sql4、创建数据库用户shell> mysql -uroot -p mysqlmysql> GRANT ALL ON cacti.* TO cactiuser@localhost IDENTIFIED BY 'cactipassword';mysql> flush privileges;5、配置include/config.php$database_type = "mysql";$database_default = "cacti";$database_hostname = "localhost";$database_username = "cactiuser";$database_password = "cactipassword";/* load up old style plugins here */$plugins = array();//$plugins[] = 'thold';/*Edit this to point to the default URL of your Cacti installex: if your cacti install as at http://serverip/cacti/ thiswould be set to /cacti/*/$url_path = "/cacti/";/* Default session name - Session name must contain alpha characters */#$cacti_session_name = "Cacti";6、设置目录权限chown -R cactiuser rra/ log/cactiuser为系统存在的用户，为了收集数据。7、配置计划任务echo "*/5 * * * * cactiuser php /var/www/html/cacti/poller.php > /dev/null 2>&1">>/etc/crontabservice crond restart8、完成cacti的安装1) 在浏览器中输入：http://www.yourdomain. com/cacti/默认用户名：admin 密码：admin2) 更改密码3）设置cacti用到的命令路径至此已经安装完成
