Cacti+Nagios完全攻略（三）spine及最新补丁的安装
由于cmd.php不能满足项目需求，用spine替换掉1.下载Cacti-spine最新版本，(要同使用的cacti版本相匹配)
下载地址:http://www.cacti.net/downloads/spine/
2.由于安装spine，测试中发现，执行—with-snmp= /usr/include/net-snmp/报“error: Cannot find UCD-SNMP libraries(snmp)”这个错误，最后只能卸载之前用yum安装的net-snmp
a.卸载net-snmp
#yum list |grep net-snmp
#yum remove net-snmp
b.安装net-snmp源包
下载地址：http://sourceforge.net/projects/net-snmp/files/net-snmp/5.4.3/
#tar zxvf net-snmp-5.4.3.tar.gz
#cd net-snmp-5.4.3
#./configure --prefix=/usr/local/net-snmp
#make ;make install
#cp EXAMPLE.conf /usr/local/net-snmp/share/snmp/snmpd.conf
#ln -s /usr/local/net-snmp/bin/* /usr/local/bin/
#/usr/local/net-snmp/sbin/snmpd -c /usr/local/net-snmp/share/snmp/snmpd.conf
#echo“/usr/local/net-snmp/sbin/snmpd /usr/local/net-snmp/share/snmp/snmpd.conf ”>>/etc/rc.local
3.安装spine
#wget http://www.cacti.net/downloads/spine/cacti-spine-0.8.7g.tar.gz
#tar zxvf cacti-spine-0.8.7g.tar.gz
#cd cacti-spine-0.8.7g
#./configure --prefix=/usr/local/cacti-spine --with-snmp=/usr/local/net-snmp
#make && make install
#cd /usr/local/cacti-spine/etc/
#cp spine.conf.dist spine.conf
#vi spine.conf
#service httpd restarat
#crontab -e（设置轮询刷新时间）

接着在cacti页面上面设置poller选择spine，如下图设置

这样就结束了.
4.由于这段时间发现cacti出问题，用snmkwalk能抓到数据，但图出不来，如下情况

后来查看了cacti日子信息后发现提示以下错误：

经过谷歌搜索，发现最近spine有bug，需要安装最新补丁.
+Patched 0.8.7g
+-bug#0001669: Problems with getting data from script using SPINE on Windows Server 2003 x32
+-bug#0001829: Wrong string numerical value got from Spine SNMP poller
+-bug: Net-snmp API issues cause spine crashes with some SNMP agents
+-bug: Host list not properly initialized
+-bug: Mutex locking issues cause deadlocks in Windows
+-bug: Escape windows type back slashes in scripts
下载最新补丁：
http://www.cacti.net/downloads/spine/patches/0.8.7g/unified_issues.patch
下载好的补丁放在cacti-spine-0.8.7g目录下面
然后需重新执行安装步骤
#./configure --prefix=/usr/local/cacti-spine --with-snmp=/usr/local/net-snmp
# patch -p1 -N < unified_issues.patch
#make && make install
#cd /usr/local/cacti-spine/etc/
#cp spine.conf.dist spine.conf
##vi spine.conf （覆盖后重新修改连接数据库的账号密码）

#service httpd restarat
重新查看cacti日志：

再mark一下（2011.03.23）
报以下错误
03/23/2011 11:57:01 AM - PHPSVR: Poller ERROR: Input Expected, Script Server Terminating
03/23/2011 11:57:01 AM - PHPSVR: Poller ERROR: Input Expected, Script Server Terminating
03/23/2011 11:57:01 AM - PHPSVR: Poller ERROR: Input Expected, Script Server Terminating
03/23/2011 11:57:01 AM - SPINE: Poller FATAL: Connection Failed, Error:'1040', Message:'Too many connections' (Spine thread)
解决方法：
vim /etc/my.cnf
增加set-variable = max_connections=500
/etc/init.d/mysqld restart
再mark一下（2011.04.27）
最近发现cacti监控表每隔10分钟抓不到数据，很奇怪，也不知道哪位同事修改了Console -> Cacti Settings -poller-Poller Interval为30秒，后来改回一分钟一切恢复正常
http://blog.运维网.com/attachment/201104/201644896.jpg
因为在系统本身是设置一分钟，觉得有冲突
# crontab -e
*/1 * * * * env LANG=C /usr/bin/php /var/www/html/poller.php > /dev/null 2>&1
问题图如下：
