安裝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安裝完畢

安裝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
改為：com2sec notConfigUser 127.0.0.1 public
2、access notConfigGroup "" any noauth exact systemview none none
改為：access notConfigGroup "" any noauth exact all none none
3、#view all included .1 80
將前面的 # 注釋 去掉。
保存退出 :wq
[root@localhost usr]# service snmpd restart

使用yum安裝更方便：
[root@localhost usr]# yum install net-snmp
[root@localhost usr]# yum update net-snmp
配置還是使用上面的方法修改。

或者使用：net-snmp-5.1.4.tar.gz安裝
[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
運行snmpconf -g basic_setup，會在當前目錄下生成一個snmpd.conf配置文件：
[root@localhost local]# snmpconf -g basic_setup
運行後會出現一個詢問菜單，按如下步驟進行回答：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 you want to configure the agents ability to monitor file sizes? (default = y): n（如果想監控文件的大小，可以選y）

4．運行net-snmp：
# snmpd -c /path/snmpd.conf (要上面生成的絕對路徑)
測試一下看看net-snmp是否配置成功：
#snmpwalk -v 1 -c public localhost .1 (是否可以從.1開始採集伺服器數據)
#snmpwalk -v 1 -c public localhost dskPercent.1 (看看剛配置過的硬碟監測是否成功)
如果有數據了，恭喜你snmp安裝成功了。

註：如果你機器內沒有snmpwalk和snmpge命令，請到安裝盤里查找 net-snmp-utils 包，rpm -ivh net-snmp-utils-*.rpm 只後這兩個命令就

在系統里了。其他包也都在安裝盤里 確保安裝這四個包就OK

安裝/ 配置cacti
[root@localhost usr]# useradd cactiuser -g users

$database_type = 「mysql」;
$database_default = 「cactidb」;

全部設置完畢。
打開瀏覽器 http://192.168.1.254/cacti 進入cacti的初始設置頁面
第一次默認登陸賬號：admin 密碼 admin
登陸後在新改個密碼就OK
需要說明的還有路徑
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
如果你是按我的步驟做的 那上面的路徑一定不會錯。

註：此時graphs還不能顯示圖形，需要將服務重新啟動一下
[root@localhost scripts]# service snmpd restart
[root@localhost scripts]# service mysql restart
[root@localhost scripts]# service httpd restart

『貳』 看哦，是這么回事，我在linux centos下安裝監控cacti，但是沒有檢測到圖，請問如何解決

檢查 rrd root , 目錄下的rra 下有沒有文件 沒有的話初始化 rrd toos

『叄』 linux 安裝cacti 編譯GD庫出錯，求高手解釋...

[root@gfwebserver gd-2.0.35]# vi gd_png.c

#ifdef HAVE_CONFIG_H
#include "config.h"
#endif

#include <stdio.h>
#include <math.h>
#include <string.h>

#ifdef HAVE_LIBPNG

#include "gdhelpers.h"

『肆』 虛擬機linux下安裝cacti不顯示圖片

cacti這東西不太好弄。我曾經用了兩個星期，能出了一個簡圖，但是不能動態更新，估計是snmp沒有整好。

後來沒了耐心，放棄了。唉~

『伍』 我在linux下安裝的cacti用來監控windows其他數據都有、但CPU、內存只有圖沒有數據，希望高手指點!

您還不如試試雲網管軟體呢~~~
美信雲網管迷你版是歷經大客戶磨煉的、國內第一款永久免費的企業級網管軟體，
具備以下強大的功能：

1. 支持監控10台Windows、Linux伺服器和網路設備，或者50個PING和URL；

2. 監控內容包括：CPU、內存、磁碟、網卡、進程、埠、目錄、文件、日誌、埠up/down、流量、
帶寬、丟包率、錯包率、網路可用性、URL下載時間、網頁防篡改等上百個指標參數；

3. 支持郵件、短消息、聲音和遠程聲音告警；

4. 支持健康報告、指標報告、對比報告等多種報告；

5. 支持狀態統計、我的儀表盤、管理對象和監測點等多種視圖顯示

『陸』 如何使用CactiEZ進行監控Linux主機

1.要監視一台Linux主機，需要在被監控的主機上安裝net-snmp相關軟體包，CentOS安裝可使用「yum -y install net-snmp」命令：
# yum -y install net-snmp
……
Complete!
2.修改配置文件命令：
# vi /etc/snmp/snmpd.conf 確保snmpd.conf文件中包含以下內容：
com2sec notConfigUser default public
group notConfigGroup v1 notConfigUser
group notConfigGroup v2c notConfigUser
view systemview included .1
access notConfigGroup "" any noauth exact systemview none none
syslocation www.cactiez.com #系統的物理位置
syscontact Root [email protected] # 聯系人
pass .1.3.6.1.4.1.4413.4.1 /usr/bin/ucd5820stat
保存並退出
3.開啟snmpd服務：
# service snmpd start
4.設置snmpd每次開機時自動啟動：
# chkconfig snmpd on。該命令執行完成後不會返回任何結果
5.檢查snmpd服務是否已在運行：
# netstat -nlup | grep ":161"
udp 0 0 0.0.0.0:161 0.0.0.0:* 16986/snmpd
該命令檢查本地是否已在監聽UDP埠161，如果返回類似以上結果，表明snmpd服務啟動成功。

『柒』 linux下安裝cacti如何監測windows客戶端

1監控時候把模板選中那個 windows的就好
2開啟windows snmp代理服務
3保證鏈路ping通 udp數據包在linux監控伺服器和window間要通

『捌』 求cacti軟體在Linux下安裝的批處理命令

1. 檢查程序中的.H文件所在路徑，並將相應路徑添加到系統PATH中：
#PATH=[路徑名]:$PATH
2. 執行C編譯，並指定目標文件名：
#gcc [源文件名] -o [目標文件名]
執行C++編譯，並指定目標文件名：
#g++ [源文件名] -o [目標文件名]
3. 改變目標文件屬性為可執行文件：
#chmod +x [目標文件名]
4. 如需將多個可執行文件連續執行，可生成批處理文件：
#vi [批處理文件名]
可執行文件名1
可執行文件名2
可執行文件名3
...
並將該文件屬性也改為可執行文件。

『玖』 Linux下簡單配置安裝cactisnmp再次安裝怎麼解決

以前確認過機器上安裝了snmp，但是這是redhat自帶的，據說裡面是沒有snmpwalk,snmpget這些命令的，所以我這里要重新
編譯安裝NET-SNMP
官方網站

解決辦法：
ln -s libelf.so.1 /usr/lib/libelf.so

繼續make，成功了：）
make install
安裝成功。

鏈接過去
ln -s /usr/local/net-snmp/bin/* /usr/local/bin/

cp EXAMPLE.conf /usr/local/net-snmp/share/snmp/snmpd.conf

/usr/local/net-snmp/sbin/snmpd //啟動SNMP服務

vi /etc/rc.d/rc.local
//在rc.local上加入一行/usr/local/net-snmp/sbin/snmpd,系統啟動時啟動SNMP服務

現在再回頭看看cacti的錯誤
錯誤：/usr/local/bin/snmpwalk
錯誤：/usr/local/bin/snmpget
錯誤：/usr/local/bin/snmpbulkwalk
錯誤：/usr/local/bin/snmpgetnext
再次點開，這次就沒有以上的錯誤啦。點Finish
輸入用戶名和密碼admin/admin

登陸後點擊graph圖標，圖沒有出來。繼續查找下原因，快要成功了：）
查看後台日誌cacti裡面的log/cacti.log，日誌如下：

『拾』 cacti監控伺服器怎樣添加linux主機

首先點擊Configuration——Hosts——Create Host來進入新增主機界面。

Host Name選項填寫一個唯一的名稱，Visible Name填寫任意你覺得易讀的名稱。
Groups選擇一個已存在的組名，或者在New Group處填寫一個新的分組。
Agent interfaces的IP address填寫為被監控端IP地址，port保持默認即可。
Description處可以填寫任意描述（可空）。
其他保持默認即可。
