请教高手帮我指点一下这是我写的配置文档
本安装手册假定计算机上已经成功安装MySQL，Apache，PHP；PHP安装目录为/usr/local/php；Apache
及PHP的DocumentRoot为/var/web；且MySQL数据库的root用户密码为taiyu。
1.建立cactiuser用户
useradd cactiuser
2.设置mysql
create database cacti;
grant all privileges on cacti.* to cacti identified by 'taiyu';
grant all privileges on cacti.* to cacti@localhost identified by 'taiyu';
3.安装net-snmp相关包
安装前请先检查系统中是否有snmpwalk和snmpget两个命令。如果有，则可以跳过以下步骤。
rpm -ivh net-snmp-5.0.9-2.30E.6.i386.rpm
rpm -ivh net-snmp-devel-5.0.9-2.30E.6.i386.rpm
rpm -ivh net-snmp-perl-5.0.9-2.30E.6.i386.rpm
rpm -ivh net-snmp-utils-5.0.9-2.30E.6.i386.rpm
4.下载并安装rrdtool
a.下载网址:
http://people.ee.ethz.ch/~oetiker/webtools/rrdtool/pub/rrdtool-1.0.x/rrdtool-1.0.50.tar.gz
b.安装：
(1) ./configure
(2) make && make install
我这里使用的是rpm包安装的，文件包里有。
rpm –ivh rrdtool-1.0.38-1.i386
rpm –ivh rrdtool-1.0.38-1.src
rpm –ivh rrdtool-devel-1.0.38-1.i386
注：由于rrdtool1.2版本已经不再自带外部的lib库，所以需要从http://people.ee.ethz.ch/~oetiker/webtools/rrdtool/pub/libs/
下载这些库来安装。建议还是使用1.0的版本，比较方便。
5.安装Cacti
a.下载：
http://www.cacti.net/downloads/
b.安装：
(1)tar -xzvf cacti-*.tar.gz -C /www/web/
(2)mv cacti-* cacti
(3)cd cacti
(4)mysql -uroot -ptaiyu cacti < cacti.sql
(5)chown -R cactiuser rra/ log/
(6)vi include/config.php
找到以下内容：
$database_type = "mysql";
$database_default = "cacti";
$database_hostname = "localhost";
$database_username = "cactiuser";
$database_password = "cactipw";
修改为以下内容：
$database_type = "mysql";
$database_default = "cacti";
$database_hostname = "localhost";
$database_username = "cacti";
$database_password = "taiyu";
下面要创建：
[root@localhost ~]# crontab -u cactiuser -e
加入以下内容：
*/5 * * * * php /var/web/cacti/poller.php > /dev/null 2>&1
6.配置snmpd 的配置文件/etc/snmp/snmp.conf
vi /etc/snmp/snmp.con 进入配置文件找到修改以下几处：
# sec.name source community
com2sec notConfigUser 192.168.1.232 public //这里是我本地的机器ip地址，请改成你自己的机器地址就ok了。
# groupName securityModel securityName
group notConfigGroup v1 notConfigUser
group notConfigGroup v2c notConfigUser //这几行是系统默认开启的。
# name incl/excl subtree mask(optional)
view systemview included .1.3.6.1.2.1.1
view systemview included .1.3.6.1.2.1.25.1.1 //找到此去掉后两行的#
# group context sec.model sec.level prefix read write notif
access notConfigGroup "" any noauth exact all none none ///找到次处，这里要修改成这样。
## incl/excl subtree mask
view all included .1 80 //找到次处，修改去掉80这一行的#号。
这里如有错误，请到本文档外面有个snmp.conf文件里去做对比。
保存关闭.
11.重新能启动snmpd 启动命令 /etc/init.d/snmpd start
如果有防火墙，打开UDP 161端口。
最后运行查看snmp的端口号
[root@localhost snmp]# netstat -ln|grep 161
udp 0 0 0.0.0.0:161 0.0.0.0:*
如果看到161端口，说明snmpd服务器启动成功。
12．设置snmpd服务默认启动：chkconfig --level 3 snmpd on
如果没有安装snmp服务，请在RH的安装光盘上找到net-snmp.rpm，再安装。
13．打开本机的SNMP服务，
这样就基本配置好了，现在做一个测试：
[root@localhost ~]# ps -ef |grep snmpd //应该出现下面两行。
root 16874 1 0 14:53 ? 00:00:00 /usr/sbin/snmpd -Lsd -Lf /dev/null -p /var/run/snmpd -a
root 16880 16763 0 14:53 pts/1 00:00:00 grep snmpd
测试二，如下：
[root@localhost ~]# free -m
total used free shared buffers cached
Mem: 939 913 26 0 125 561
-/+ buffers/cache: 226 713
Swap: 1983 0 1983
这里的测试,不知道怎么会事,正常的在下面,我应该怎么解决呢?
[root@localhost ~]# php /var/www/html/cacti/poller.php

.页面设置：
(1)在浏览器输入：http://ip/cacti
进入cacti的初始设置页面，在这里我们要输入一些原始的信息。流程如下：
NEXT -> 输入一些信息，如rrdtool、php、snmpwalk、snmpget的位置
使用ucd-snmp还是net-snmp等 -> 输入原始的用户名和密码(admin/admin) -> 更改admin用户的密码 -> Save
至此，Cacti的安装已经完成，现在可以在浏览器中进入Cacti的界面了 |
