rrdtool

安装rrdtool

[root@localhost usr]# tar zxvf rrdtool-1.0.50.tar.gz
[root@localhost usr]# cd rrdtool-1.0.50
[root@localhost rrdtool-1.0.50]# ./configure
[root@localhost rrdtool-1.0.50]# make && make install

我的是fedora 7,用下面的方法。

[root@localhost usr] yum install rrdtool

Rrdtool安装完毕

安装net-snmp、snmpwalk和snmpget命令

[root@localhost usr]# rpm -qa | grep net-snmp
net-snmp-5.0.9-2.30E.15
net-snmp-devel-5.0.9-2.30E.15
net-snmp-libs-5.0.9-2.30E.15
net-snmp-utils-5.0.9-2.30E.15
[root@localhost usr]# vi /etc/snmp/snmpd.conf
更改 1、com2sec notConfigUser  default       public
       改为：com2sec notConfigUser   127.0.0.1       public
       2、access  notConfigGroup ""      any       noauth    exact  systemview  none none
       改为：access  notConfigGroup ""      any       noauth    exact  all  none  none
       3、#view all    included  .1         80
       将前面的 # 注释 去掉。
保存退出 :wq
[root@localhost usr]# service snmpd restart


使用yum安装更方便：
[root@localhost usr]#  yum install net-snmp
[root@localhost usr]#  yum update net-snmp
配置还是使用上面的方法修改。


或者使用：net-snmp-5.1.4.tar.gz安装
[root@localhost local]# tar -zxvf net-snmp-5.1.4.tar.gz
[root@localhost local]# cd net-snmp-5.1.4
[root@localhost local]# ./configure
[root@localhost local]# make
[root@localhost local]# make install
运行snmpconf -g basic_setup，会在当前目录下生成一个snmpd.conf配置文件：
[root@localhost local]# snmpconf -g basic_setup
运行后会出现一个询问菜单，按如下步骤进行回答：CODE:[Copy to clipboard]Do you want to configure the information returned in

the system MIB group (contact info, etc)? (default = y): y

The location of the system: Shenzhen, China

Do another load line? (default = y): n
Do you want to configure the agents ability to monitor file sizes? (default = y): n（如果想监控文件的大小，可以选y）

4．运行net-snmp：
# snmpd -c /path/snmpd.conf  (要上面生成的绝对路径)
测试一下看看net-snmp是否配置成功：
#snmpwalk -v 1 -c public localhost .1 (是否可以从.1开始采集服务器数据)
#snmpwalk -v 1 -c public localhost dskPercent.1 (看看刚配置过的硬盘监测是否成功)
如果有数据了，恭喜你snmp安装成功了。




注：如果你机器内没有snmpwalk和snmpge命令，请到安装盘里查找 net-snmp-utils 包，rpm -ivh net-snmp-utils-*.rpm 只后这两个命令就

在系统里了。其他包也都在安装盘里 确保安装这四个包就OK


安装/ 配置cacti
[root@localhost usr]# useradd cactiuser -g users
[root@localhost usr]# passwd cactiuser (pwd:cactipw)
[root@localhost usr]# cp cacti-0.8.7.tar.gz /var/www/html
[root@localhost usr]# cd /var/www/html
[root@localhost html]# tar -zxvf cacti-0.8.7.tar.gz
[root@localhost html]# mv cacti-0.8.6g cacti
[root@localhost html]# cd cacti
[root@localhost cacti]# /usr/local/mysql/bin/mysql -u root -p cactidb < cacti.sql
passwork:
[root@localhost cacti]# chown -R cactiuser rra/ log/
[root@localhost cacti]# cd scripts
[root@localhost scripts]# chown cactiuser:users *
[root@localhost scripts]# vi /www/htdocs/cacti/include/config.php
 $database_type = “mysql”;
$database_default = “cactidb”;
$database_hostname = “localhost”;
$database_username = “cactiuser”;
$database_password = “cactipw”;
更改用户、密码 等项 与上面给出的对应 保存退出
[root@localhost scripts]# crontab -u cactiuser -e
加入
*/5 * * * * /usr/local/php/bin/php /var/www/html/cacti/poller.php > /dev/null 2>&1
保存退出：wq

全部设置完毕。
打开浏览器 http://192.168.1.254/cacti 进入cacti的初始设置页面
第一次默认登陆账号：admin 密码 admin
登陆后在新改个密码就OK
需要说明的还有路径
snmpwalk Binary Path ： /usr/bin/snmpwalk
snmpget Binary Path： /usr/bin/snmpget
RRDTool Binary Path： /usr/bin/rrdtool
PHP Binary Path： /usr/local/php/bin/php
Cacti Log File Path： /var/www/html/cacti/log/cacti.log
Cactid Poller File Path：/var/www/html/cacti/poller.php
如果你是按我的步骤做的 那上面的路径一定不会错。

注：此时graphs还不能显示图形，需要将服务重新启动一下
[root@localhost scripts]# service snmpd restart
[root@localhost scripts]# service mysql restart
[root@localhost scripts]# service httpd restart
