2、修改cacti輪詢時間精度,以及添加監控主機

先理清下思路因爲本實驗截圖太多，以及並不是很順利，其實呢個人覺得出問題還好啦，因爲出了問題在實驗時就解決了並收穫經驗，當真正在生產環境出問題才悲劇！

1、安裝spine

2、編輯配置spine文件

3、編輯RRAs(使看圖更直觀，因爲cacti默認最小是5分鐘一刻)

4、配置spine路徑

5、修改使用spine輪詢方式

6、修改數據模版增加新增的RRAs

7、創建新主機

8、創建圖到這個主機

9、把主機加入到默認樹裏面去

安裝和配置spine支持快速輪詢

依賴包如下

1. net-snmp-devel

2. mysql-devel

3. openssl-devel

4. dos2unix

5. autoconf

6. automake

7. binutils

8. libtool

9. gcc

10. cpp

11. glibc-headers

12. kernel-headers

13. glibc-devel

[root@radius src]# yum install net-snmp-devel mysql-devel openssl-devel dos2unix autoconf automake binutils libtool gcc cpp glibc-headers kernel-headers glibc-devel

[root@radius src]# tar -zxvf cacti-spine-0.8.8a.tar.gz

[root@radius src]# cd cacti-spine-0.8.8a

[root@radius cacti-spine-0.8.8a]# ./configure --prefix=/usr/local/cacti-spine

報錯：

configure: error: Cannot find SNMP headers. Use --with-snmp= to specify non-default path

解決：

[root@radius cacti-spine-0.8.8a]# yum install net-snmp-devel

再次安裝

[root@radius cacti-spine-0.8.8a]# ./configure --prefix=/usr/local/cacti-spine

[root@radius cacti-spine-0.8.8a]# make && make install

默認配置文件模版在

/usr/local/cacti-spine/etc/spine.conf.dist

我們需要把配置文件複製到/etc/spine.conf

[root@radius cacti-spine-0.8.8a]# cp spine.conf.dist /etc/spine.conf

原因看

[root@radius cacti-spine-0.8.8a]# vim spine.h

修改配置文件

[root@radius cacti-spine-0.8.8a]# vim /etc/spine.conf

測試是否安裝成功

[root@radius cacti-spine-0.8.8a]# /usr/local/cacti-spine/bin/spine

報錯:

/usr/local/cacti-spine/bin/spine: error while loading shared libraries: libmysqlclient.so.18: cannot open shared object file: No such file or directory

解決:

[root@radius cacti-spine-0.8.8a]# ln -s /usr/local/mysql/lib/libmysqlclient.so.18 /usr/lib/libmysqlclient.so.18

再次測試

[root@radius cacti-spine-0.8.8a]# /usr/local/cacti-spine/bin/spine

報錯
SPINE: Using spine config file [/etc/spine.conf]
04/26/2013 10:53:14 AM - SPINE: Poller[0] FATAL: Connection Failed, Error:'1045', Message:'Access denied for user 'cactiuser'@'localhost' (using password: YES)' (Spine init)

原因是應爲cactiuser沒有權限訪問cacti數據庫，我修改了下cactiuser用戶的密碼就OK了

再次測試成功了出現如下圖

再次測試

[root@radius cacti-spine-0.8.8a]# /usr/local/cacti-spine/bin/spine

報錯

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

MYSQL: Connection Failed: Error:'2002', Message:'Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)'

05/02/2013 01:57:31 PM - SPINE: Poller[0] FATAL: Connection Failed, Error:'2002', Message:'Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)' (Spine init)

解決

[root@radius bin]# vim /etc/spine.conf
