前提:已经编译安装好了LAMP(mysql5.5)
一、配置服务端
1、注释中心主机,并启用虚拟主机,添加一个虚拟主机
# cd /etc/httpd/
# vim httpd.conf
注释掉:DocumentRoot "/usr/local/apache/htdocs"
启用:# Virtual hosts
Include /etc/httpd/extra/httpd-vhosts.conf
# vim /etc/httpd/extra/httpd-vhosts.conf
<VirtualHost *:80>
DocumentRoot "/web/vhosts/cacti"
ServerName cacti.fsy.com
<Directory "/web/vhosts/cacti">
Options Indexes
AllowOverride none
Require all granted
</Directory>
ErrorLog "logs/cati-error_log"
CustomLog "logs/cacti-access_log" common
</VirtualHost>
2、安装rrdtool采集工具
1)安装rrdtool之前需要安装相应的lib库,如下安装:
# yum install cairo-devel libxml2-devel pango pango-devel –y
2)
# tar xzf rrdtool-1.4.5.tar.gz
# cd rrdtool-1.4.5
# ./configure --prefix=/usr/local/rrdtool/
# make && make install
# /usr/local/rrdtool/bin/rrdtool
此时可以显示rrdtool的版本,表明安装成功!
3)创建链接
# ln -s /usr/local/rrdtool/bin/* /usr/local/bin/
3、安装SNMP服务
# yum install net-snmp net-snmp-utils –y
4、初始化安装cacti
# mkdir -p /web/vhosts
# tar xf cacti-0.8.8a.tar.gz -C /web/vhosts
# cd /web/vhosts/
# ln -sv cacti-0.8.8a cacti
# service httpd restart
5、初始化数据库并创建用户
# cd cacti
# mysqladmin creat cactidb
# mysql cactidb < cacti.sql
# mysql -e "GRANT ALL ON cactidb.* TO cactiuser@localhost IDENTIFIED BY ‘cactiuser‘"
# mysqladmin flush-privileges
6、修改cacti的配置文件
# cd include/
# vim config.php
修改以下两项
$database_default = "cactidb";
$url_path = "/";
7、创建执行用户cactiuser,并修改目录属主和属组
# /web/vhosts/cacti
# useradd cactiuser
# chown -R cactiuser:cactiuser rra/ log
8、安装cacti
配置本地域名解析,添加以下内容
202.207.178.6 cacti.fsy.com
然后访问cacti.fsy.com,即可开始安装
因为LAMP是编译安装的,所以在安装cacti时将/usr/local/php/bin/php
默认用户名和密码都是admin
9、为cactiuser定义任务计划,并测试
若没有crontab,需要装vixie-crons crontabs
1)定义任务计划,每五分钟执行一次poller.php
# echo ‘*/5 * * * * /usr/local/php/bin/php /web/vhosts/cacti/poller.php &>/dev/null‘ > /var/spool/cron/cactiuser
2)为使任务计划顺利执行,更改时区
# vim /etc/php.ini
修改如下内容:
date.timezone = Asia/Shanghai
3)测试
# su - cactiuser
$ /usr/local/php/bin/php /web/vhosts/cacti/poller.php
二、配置被监控的linux主机
1、修改配置文件
# vim /etc/snmp/snmpd.conf
将62行处改为如下内容,以使所有都可以访问:
access notConfigGroup "" any noauth exact all none none
将41行处改为如下内容,以允许服务端采集其数据
com2sec notConfigUser 202.207.178.6 public
启用65行
view all included .1 80
2、启动服务
# servcie snmpd restart
在服务器端操作网页,配置即可
欢迎批评指正!
