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

[root@cacti soft]#yum list |grep net-snmp

[root@cacti soft]#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/

[root@cacti soft]#tar zxvf net-snmp-5.4.3.tar.gz

[root@cacti soft]#cd net-snmp-5.4.3

[root@cacti net-snmp-5.4.3]#./configure --prefix=/usr/local/net-snmp

[root@cacti net-snmp-5.4.3]#make ;make install

[root@cacti net-snmp-5.4.3]#cp EXAMPLE.conf /usr/local/net-snmp/share/snmp/snmpd.conf

[root@cacti net-snmp-5.4.3]#ln -s /usr/local/net-snmp/bin/* /usr/local/bin/

[[email protected]]#/usr/local/net-snmp/sbin/snmpd -c /usr/local/net-snmp/share/snmp/snmpd.conf

[[email protected]]#echo“/usr/local/net-snmp/sbin/snmpd /usr/local/net-snmp/share/snmp/snmpd.conf ”>>/etc/rc.local

 

3.安装spine

[root@cacti soft]#wget http://www.cacti.net/downloads/spine/cacti-spine-0.8.7g.tar.gz

[root@cacti soft]#tar zxvf cacti-spine-0.8.7g.tar.gz

[root@cacti soft]#cd cacti-spine-0.8.7g

[[email protected]]#./configure --prefix=/usr/local/cacti-spine --with-snmp=/usr/local/net-snmp

[root@cacti cacti-spine-0.8.7g]#make && make install

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

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

[root@cacti etc]#vi spine.conf

[root@cacti etc]#service httpd restarat

[root@cacti etc]#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

[[email protected]]#./configure --prefix=/usr/local/cacti-spine --with-snmp=/usr/local/net-snmp

[[email protected]]#  patch -p1 -N < unified_issues.patch

[root@cacti cacti-spine-0.8.7g]#make && make install

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

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

[root@cacti etc]##vi spine.conf （覆盖后重新修改连接数据库的账号密码）

[root@cacti etc]#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[0] ERROR: Input Expected, Script Server Terminating

03/23/2011 11:57:01 AM - PHPSVR: Poller[0] ERROR: Input Expected, Script Server Terminating

03/23/2011 11:57:01 AM - PHPSVR: Poller[0] ERROR: Input Expected, Script Server Terminating

03/23/2011 11:57:01 AM - SPINE: Poller[0] 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

 

因为在系统本身是设置一分钟，觉得有冲突

[root@cacti ~]# crontab -e

*/1 * * * * env LANG=C /usr/bin/php /var/www/html/poller.php > /dev/null 2>&1

问题图如下：
