实战Cacti网络监控(2)——搭建Spine轻量级框架实现多线程监控

本次实验接着上次实验的环境。实战Cacti网络监控(1)——基础安装配置
实验内容：
1.监控物理主机2.Spine 多线程监控3.monitor监控插件

1.监控物理主机在物理主机上配置如下：
yum install net-snmp.x86_64 -y ##安装snmp服务
yum install net-snmp-utils.x86_64 -y
vim /etc/snmp/snmpd.conf

snmpwalk -v 1 -c public localhost IP-MIB::ipAdEntIfIndex ##-v指版本,-c指密钥,即客户端snmp.conf里面所设置的,公认的密钥组为public(这也是snmp众所都知的bug之一,不安全！,当然也可以自己改个密码),IP——MIB指获取系统(物理机)的IP信息

网页端配置
打开网页http:172.25.254.10
在左边选Device 然后点击Add

这是创建好的然后点击右上方第一个添加虚拟机监控界面Console -> Graph Trees -> (Edit) -> Graph Tree Items

2.Spine 多线程监控在虚拟主机server6上编译cacti-spine：
tar zxf cacti-spine-0.8.8h.tar.gz
cd cacti-spine-0.8.8h
《1》yum install net-snmp-devel mysql-devel openssl-devel -y ##解决依赖关系
《2》yum install dos2unix autoconf automake binutils libtool gcc cpp glibc-headers glibc-devel -y
《3》sh bootstrap
《4》./configure
《5》make && make install
cd /usr/local/spine/etc
《1》cp spine.conf.dist /etc/spine.conf
《2》vim /etc/spine.conf ##做如下修改
33 DB_Host localhost
34 DB_Database cacti
35 DB_User cacti
36 DB_Pass redhat 37 DB_Port 3306
su – cacti
