2、修改cacti轮询时间精度,以及添加监控主机

　　先理清下思路因为本实验截图太多，以及并不是很顺利，其实呢个人觉得出问题还好啦，因为出了问题在实验时就解决了并收获经验，当真正在生产环境出问题才悲剧！
　　1、安装spine
　　2、编辑配置spine文件
　　3、编辑RRAs(使看图更直观，因为cacti默认最小是5分钟一刻)
　　4、配置spine路径
　　5、修改使用spine轮询方式
　　6、修改数据模版增加新增的RRAs
　　7、创建新主机
　　8、创建图到这个主机
　　9、把主机加入到默认树里面去
　　安装和配置spine支持快速轮询
　　依赖包如下
　　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
　　报错：
　　configure: error: Cannot find SNMP headers. Use --with-snmp= to specify non-default path
　　解决：
　　[root@radius cacti-spine-0.8.8a]# yum install net-snmp-devel
　　再次安装
　　[root@radius cacti-spine-0.8.8a]# ./configure --prefix=/usr/local/cacti-spine
　　[root@radius cacti-spine-0.8.8a]# make && make install
　　默认配置文件模版在
　　/usr/local/cacti-spine/etc/spine.conf.dist
　　我们需要把配置文件复制到/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

http://better.blog.运维网.com/attachment/201305/13/1886029_1368427315dXfh.gif

　　测试是否安装成功
　　[root@radius cacti-spine-0.8.8a]# /usr/local/cacti-spine/bin/spine
　　报错:
　　/usr/local/cacti-spine/bin/spine: error while loading shared libraries: libmysqlclient.so.18: cannot open shared object file: No such file or directory
　　解决:
　　[root@radius cacti-spine-0.8.8a]# ln -s /usr/local/mysql/lib/libmysqlclient.so.18 /usr/lib/libmysqlclient.so.18
　　再次测试
　　[root@radius cacti-spine-0.8.8a]# /usr/local/cacti-spine/bin/spine
　　报错
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)
　　原因是应为cactiuser没有权限访问cacti数据库，我修改了下cactiuser用户的密码就OK了

　　再次测试成功了出现如下图

http://better.blog.运维网.com/attachment/201305/13/1886029_1368427316p1SP.gif

　　再次测试
　　[root@radius cacti-spine-0.8.8a]# /usr/local/cacti-spine/bin/spine
　　报错
　　SPINE: Using spine config file [/etc/spine.conf]

　　把DB_Host 修改成127.0.0.1就ok
　　到此安装spine完成，接下来就是如何修改成每分钟查询一次数据了
　　添加一个新的RRAs以便于我们观察的到每分钟的变化，默认的绘图行数太多看不出变化

　　编辑一下数据模版加入我们刚才建立的RRA's

http://better.blog.运维网.com/attachment/201305/13/1886029_1368427330P5n5.gif

　　修改一下setp为60秒，默认是300

http://better.blog.运维网.com/attachment/201305/13/1886029_1368427330dlg5.gif

　　然后保存
　　设置spine路径

　　我们来设置轮询时间
