5.cacti的安裝：

依賴性包：

yum -y install make gcc libxml2-devel pango-devel perl-ExtUtils-MakeMaker

tar zxf rrdtool-1.4.4.tar.gz

cd rrdtool-1.4.4

./configure&& make && make install

[root@desk32 ~]# ln -s /opt/rrdtool-1.4.4/bin/rrdtool /usr/local/bin/

[root@desk32 ~]# tar zxf cacti-0.8.7h.tar.gz-C /var/www/html/

[root@desk32 ~]# mv /var/www/html/cacti-0.8.7h/ /var/www/html/cacti

[root@desk32 ~]# cd /var/www/html/cacti/

[root@desk32 cacti]# useradd cacti

[root@desk32 cacti]# chown cacti rra log -R

[root@desk32 cacti]# vim include/config.php

/* make sure these values refect your actual database/host/user/password */

$database_type = "mysql";

$database_default = "cacti";

$database_hostname = "localhost";

$database_username = "cacti";

$database_password = "cacti";

$database_port = "3306";

$database_ssl = false;

[root@desk32 cacti]# mysql -pwestos cacti < cacti.sql

Add a line to your /etc/crontab file similar to:

###the crontab must run by user of cacti#####

[root@desk32 cacti]# crontab -u cacti -e

*/5 * * * *php /var/www/html/cacti/poller.php > /dev/null 2>&1

[root@desk32 cacti]# /etc/init.d/crond status

crond (pid1476) is running...

[root@desk32 cacti]# /etc/init.d/httpd start

Point your web browser to:

http://your-server/cacti/(user:admin passwd: admin)進入後強制修改密碼

http://desk32/cacti

今天在做的時候發現一個問題：

無法顯示字體：

經檢查是系統上沒有安裝字體：

最快的解決辦法就是從其他機子上覆制：

[root@desk82 mnt]# scp -r /usr/share/fonts/* desk32:/usr/share/fonts/

刷新後問題即解決

1).進入 cacti 後需確認更改以下位置:

Console>Settings>General

SNMP Community 後填的密鑰必須與/etc/snmp/snmpd.cond下的

com2sec locallocalhostpublic

com2sec mynetwork192.168.122.0/24public

後的public處的字段相同，否則信息將會採集不到

2）安裝cacti的加速插件：spine

選擇 spine 是爲了加快速度, cmd.php 是一個 php 寫的調度程序,而 spine

是用 C 寫的 , spine 的性能遠遠優於 cmd.php , 當監控的設備有很多時 ,cmd.php 的性能就跟不上了,只能用 spine 來調度,因此選擇 spine。

需要一些包：

1.net-snmp-devel

2.mysql-devel

3.openssl-devel

and the toolchain

1.dos2unix

2.autoconf

3.automake

4.binutils

5.libtool

6.gcc

7.cpp

8.glibc-headers

9.kernel-headers

10.glibc-devel

patch

[root@desk32 ~]# tar zxf cacti-spine-0.8.7h.tar.gz

[root@desk32 ~]# cd cacti-spine-0.8.7h

[root@desk32 cacti-spine-0.8.7h]# ./configure && make && make install

[root@desk32 cacti-spine-0.8.7h]# cd /usr/local/spine/etc/

[root@desk32 etc]# cp spine.conf.dist spine.conf

[root@desk32 etc]# vim spine.

conf

DB_Hostlocalhost

DB_Databasecacti

DB_Usercacti

DB_Passcacti

DB_Port3306

DB_PreG1

啓動spine：

[root@desk32 cacti-spine-0.8.7h]# cd /usr/local/spine/bin

[root@desk32 bin]# ./spine

SPINE: Using spine config file [../etc/spine.conf]

SPINE: Version 0.8.7h starting

SPINE: Time: 0.1049 s, Threads: 5, Hosts:

設置：

Console > Settings > Paths > Alternate Poller Path > Spine Poller File Path ,將“/usr/local/spine/bin/spine”填入文本框,然後點擊“保存”按鈕。

3）cact的監控插件setting與monitor的安裝：

先安裝：cacti-plugin

[root@desk32 ~]# tar zxf cacti-plugin-0.8.7h-PA-v3.0.tar.gz

[root@desk32 ~]# cd cacti-plugin-arch/

[root@desk32 cacti-plugin-arch]# mysql -ucacti -pcacti cacti < pa.sql

[root@desk32 cacti-plugin-arch]# vim /v

ar/www/html/cacti/include/config.php

添加：

$url_path = "/cacti/";

[root@desk32 cacti-plugin-arch]# cp cacti-plugin-0.8.7h-PA-v3.0.diff /var/www/html/cacti/

[root@desk32 cacti-plugin-arch]# cd /var/www/html/cacti/

[root@desk32 cacti]# patch -p1 -N < cacti-plugin-0.8.7h-PA-v3.0.diff

安裝插件setting與monitor

[root@desk32 ~]# tar zxf settings-v0.71-1.tgz -C /var/www/html/cacti/plugins

[root@desk32 ~]# tar zxf monitor-v1.3-1.tgz -C /var/www/html/cacti/plugins

設置：

Consloe ->User Management -->admin -->Realm Permissions 選中Plugin Management 並保存，這樣在Utilities下就會多出一個Plugin Management選項：

選擇Plugin Management：

4）創建監控點：

目前cacti只監控localhost不會監控其他主機：

現在添加主機desk3.example.com 192.168.122.3與desk82.example.com 192.168.122.82

注意：

添加的兩個的主機上安裝snmpd服務/etc/snmp/snmpd.conf的配置與cacti主機的配置一樣：並啓動服務

在desk32上驗證：

[root@desk32 cacti-plugin-arch]# snmpwalk -v 1 -c public 192.168.122.3 IP-MIB::ipAdEntIfIndex

IP-MIB::ipAdEntIfIndex.127.0.0.1 = INTEGER: 1

IP-MIB::ipAdEntIfIndex.192.168.122.3 = INTEGER: 2

[root@desk32 cacti-plugin-arch]# snmpwalk -v 1 -c public 192.168.122.82 IP-MIB::ipAdEntIfIndex

IP-MIB::ipAdEntIfIndex.127.0.0.1 = INTEGER: 1

IP-MIB::ipAdEntIfIndex.192.168.122.82 = INTEGER: 2

進入 Cacti 的 console 面板,點擊“Devices”進入設備面板,

Hostname上寫的主機名一定要有解析，保險期間填寫ip下的Monitor Host選中要不然在Monitor的頁面上沒有監控的主機圖標；

爲desk3創建圖片：

同樣的方法創建主機二desk82.example.com

5）將添加的主機添加到默認的Graph Trees中：

console— > Graph Trees→ add

同樣添加desk82.example.com

6）爲已有 host 添加新的監控圖

( 1 )在 console 控制檯下點擊 “ New Graphs”,選擇要添加監控圖的主機。在

GraphTemplates 中選擇一個 Graph 模板 , 本例選擇 SNMPCeneric OID Template,點擊 create 按鈕

(2)填寫信息,在“ Title”文本框中填寫 Graph 的名字,在“Vertical Lable”文本框中填寫描述信息或是所繪圖片使用的單位等,顯示在所繪圖片的左側,在“ name”文本框中填寫此數據源的名字,在“ LegendColor”中選擇畫圖使用的顏色,在“Legend Text”填寫圖例的名字,在“OID”文本框中填寫要監控的主機的
