启动一下 snmp ,并加入自启动
service snmpd start
chkconfig snmpd on
chkconfig snmpd on
2. 下载 cacti 的 php 程序
# wget http://www.cacti.net/downloads/cacti-0.8.7e.tar.gz
# tar -zxvf cacti-0.8.7e.tar.gz
# mv cacti-0.8.7e cacti
# tar -zxvf cacti-0.8.7e.tar.gz
# mv cacti-0.8.7e cacti
3. 配置 cacti 数据库
编辑 cacti/include 下的 config.php 和 global.php 把里面相应的数据库连接设置好
接着新建一个数据库 cacti 并导入数据库文件
# mysql -hlocalhost -uroot -p123 cacti < cacti.sql
4. 安装 cacti 的 php 程序
访问你的 cacti 目录所在的网址，进入安装界面，一路next下去就好了。来到了登录界面，嘿嘿，用户名密码都是 admin 当你登录以后马上要你改密码。
5. 运行 poller_export.php 并添加 cron job
我以上4步都搞得很顺利，这第5步差点没搞死我，这步出错，你将啥图也看不到
先来改目录权限
chown -R cacti:cacti rra/ log/
或
chmod 0777 rra/ log/
接着，在命令行运行这个，当然要改成你的路径
php /www/21andy.com/cacti/poller.php
我运行的结果却出现了无法连接 MySQL 数据库，要我检查配置文件，我擦，明明是正确的，不然我刚程序怎么装的，我擦擦擦！Google了半天也没找到方法，最终还是百度了半天解决了

原因找到了，修正方法如下：
一般我们的 mysql.sock 是放在 /tmp 目录的，可这丫的cacti非用 /var/lib/mysql/mysql.sock 这个文件，所以，给他建个快捷方式吧
ln -s /tmp/mysql.sock /var/lib/mysql/mysql.sock
再运行上面那条命令，OK! 这下不出错了，后台也看到图了.
最后，加入 cron job
