cacti 从头到脚之cacti的安装及简单配置

废话不多说直接正题

主机规划

lo-cacti1:10.5.10.200

linux-www1:10.5.10.55

linux-www2:10.5.10.54

win7:10.5.10.45

上传/下载包仓库 /data0/software

步骤如下可参看www.cacti.net FAQ

lo-cacti1 配置

#yum install -y httpd mysql mysql-devel mysql-server php php-xml php-mysql php-ldap net-snmp net-snmp-devel net-snmp-libs net-snmp-utils

#/etc/init.d/httpd start (访问10.5.10.200 看到apache测试页）

#/etc/init.d/mysqld start

将服务加入开机自启动

#chkconfig --level 35 httpd on

#chkconfig mysqld on

#chkconfig snmpd on

配置php.ini

#vi /etc/php.ini 修改时区为

data.timezone = Asia/Shanghai

测试php

#cat /var/www/html/index.php

<?php

phpinfo();

?>

再次访问10.5.10.200/index.php 可以看到php的测试页及支持的相关模块

配置httpd

#cat /etc/httpd/conf.d/cacti.conf

Alias /cacti /var/www/html

<Directory /var/www/html/>

DirectoryIndex  index.php

Options-Indexs

AllowOverride all

    order deny,allow

    allow from all

    AddType application/x-httpd-php .php

    php_flag magic_quotes_gpc on

    php_flag track_vars on

</Directory>

#/etc/init.d/httpd restart

安装rrdtool

安装rrdtool 所需的库

#yum install -y cairo-devel libxml-devel libxml2-devel pango-devel

#tar xvf rrdtool-1.4.7.tar.gz;cd rrdtool-1.4.7;./configure --prefix=/usr/local/rrdtool;make &&make install

#ln -s /usr/local/rrdtool/bin/*   /usr/local/bin/

简单配置snmp

#cat /etc/snmp/snmp.conf

定位到41行修改为

#sec.namesourcecommunity

com2secnotConfigure127.0.0.1public

62行修改为

#groupcontextsec.modelsec.levelprefixreadwrite notif

accessnotConfigGroup ""any noauthexact allnonenone

86行修改为

##incl/exclsubtreemask

viewallincluded.180

#service snmpd restart

安装cacti

#tar xvf cacti-0.8.8b.tar.gz;mv cacti-0.8.8b/* /var/www/html/

#chown -R apache.apache /var/www/html

创建cacti数据库

#mysql

>create database cacti;

>insert into mysql.user(host,user,password) values (‘localhost‘,‘cacti‘,password(‘cacti123‘));

>flush privileges;

>grant all on  cacti.* to cacti@‘localhost‘ identified by ‘cacti123‘;

>\q

导入cacti.sql

#cd /var/www/html;mysql -ucacti -pcacti123 cacti<cacti.sql

修改网站配置文件，使用正确连接数据库参数

#vi include/config.php 末尾几行

$database_type = "mysql";

$database_default = "cacti";

$database_hostname = "localhost";

$database_username = "cacti";

$database_password = "cacti123";

$database_port = "3306";

开始安装cacti 浏览器打开http:10.5.10.100/install

note:Cacti Installation Guide  编译安装的需要确认以下路径全部被found

rrdtool binary path

php binary path

snmpwalk binary path

snmpget binary path

snmpbulkwalk binary path

snmpgetnext binary path

cacti log file path

"finish" -> 进入登陆界面（首次登陆用户名密码都是admin）cacti第一次登陆后会强制更改密码（如报错错/cacti/auth_changepassword.php was not found on this serve） 则须按照上述httpd配置添加/etc/httpd/conf.d/cacti.conf配置文件

cacti全局配置

console ->settings ->General-save

crontab 计划任务

#crontab -e

*/5 * * * * env LANG=C /usr/bin/php /var/www/html/poller.php > /dev/null 2>&1

然后转到Graph，tree下面就可以看到localhost的监控图（默认监控localhost），类似如下图

这篇就先记录下cacti的安装过程，下一篇cacti 添加linux主机监控和自定义主机模板
