1.配置安装cacti及测试
A）配置安装cacti# yum install rrdtool mysql-server php httpdphp-mysql php-xml net-snmp net-snmp-utils- y #安装cacti之前要安装的包
# cd /mnt/
# ls
cacti-0.8.8h.tar.gz php-snmp-5.3.3-26.el6.x86_64.rpm
cacti-spine-0.8.8g.tar.gz

# tar zxf cacti-0.8.8h.tar.gz -C/var/www/html/#解压到/var/www/html/目录
# cd /var/www/html/
# ls
cacti-0.8.8h
# ln -s cacti-0.8.8h/ cacti #作软链接
# ls
cacticacti-0.8.8h
# /etc/init.d/mysqld start #开启数据库
# mysql_secure_installation #初始化，默认没密码，这里将密码设置成了redhat
# cd cacti/
# mysql -predhat -e "create databasecacti" #创建名为cacti的数据库
# mysql -predhat cacti < cacti.sql #将cacti.sql文件导入到cacti数据库中
# mysql -predhat -e "grant all oncacti.* to cacti@localhost identified by 'redhat'" #创建本地cacti用户，并将cacti数据库的所有权限给cacti用户
# cd include/
# vim config.php #修改配置文件
29 $database_username ="cacti"; #刚创建的cacti数据库的用户名
30 $database_password ="redhat"; #用户cacti的密码
39 $url_path ="/cacti/";

在测试之前，时间得同步
B）测试 172.25.25.1/cacti登陆 用户名：admin 密码：admin
第一次登陆，会提示修改密码
登陆之后，如图:
点击graphs，如图：
# cd rra #采集数据存放的位置
# ls
等待5分钟之后
# ls #已经有数据了
localhost_load_1min_5.rrd localhost_mem_swap_4.rrd localhost_users_6.rrd
localhost_mem_buffers_3.rrd localhost_proc_7.rrd
查看图像，如图：
2.监控服务端2的资源及测试A）在服务端2安装net-snmp及配置# yum install net-snmp* -y #安装
# cd /etc/snmp/
# vim snmpd.conf #进入配置文件
40 # sec.name source community
41 #com2secnotConfigUserdefault public
42 com2sec local localhost wen #添加本地资源，名字任意（wen）
43 com2sec mynetwork172.25.25.0/24 wen #允许25网段的监控
49 #group notConfigGroup v1 notConfigUser
50 #group notConfigGroup v2c notConfigUser

IP-MIB::ipAdEntIfIndex.127.0.0.1 = INTEGER: 1
IP-MIB::ipAdEntIfIndex.172.25.25.2 = INTEGER: 2
在服务端1测试，正常

B）在图形界面添加设备及测试选择add添加设备
依次填写设备名、ip、类型；将默认的public改写成文件里添加的名字（wen）选择create
选择create之后，如下图，点击Create Graphs for this Host
如下图选择，点击create，设备添加成功
点击Graph Trees之后，如图，点击Default Trees
如图，点击Add
在Tree ltem Type中选择Host Host中选择server2 Round Robin Archive中选择5 Minute，点击create
C）测试点击graphs
等5分钟后刷新，如图：
3.cacti支持多线程的配置A）安装配置cacti-spine# yum install -y net-snmp-devel mysql-developenssl-devel dos2unix autoconf binutils libtool gcc cpp glibc-headerskernel-headers gilbc-devel #安装安装cacti-spine之前所需要的包
# ls
cacti-0.8.8h.tar.gz cacti-spine-0.8.8h.tar.gz
php-snmp-5.3.3-26.el6.x86_64.rpm
# tar zxf cacti-spine-0.8.8h.tar.gz
# cd cacti-spine-0.8.8h
# sh bootstrap #检查编译环境
# ./configure
# make
# make install
# cd /usr/local/spine/
# ls
binetc
# cd etc/
# cp spine.conf.dist /etc/spine.conf #配置文件
# vim /etc/spine.conf
33 DB_Host localhost #本地数据库
34 DB_Database cacti #数据库的名字
35 DB_User cacti #数据库的用户
36 DB_Pass redhat #密码
37 DB_Port 3306 #端口
# cd ..
# cd bin/
# ls #启动脚本
spine
# pwd
/usr/local/spine/bin
# su - cacti
$ /usr/local/spine/bin/spine #测试脚本，正常
SPINE: Using spine config file
SPINE: Version 0.8.8h starting
SPINE: Time: 0.0820 s, Threads: 5, Hosts: 3
B）在图形界面添加脚本路径及更改poller的类型点击Setting中的Paths添加启动sping脚本的路径
将cmd.php换成spine就可以支持多线程了。（线程设置在Devices中将Host Template）
4.用命令行设置监控及测试
A）用命令行设置监控# uptime | awk '{print$1,$(NF-2),$(NF-1),$(NF)}' | sed 's/,//g'
15:16:15 0.00 0.00 0.00
# uptime | awk '{print$1,$(NF-2),$(NF-1),$(NF)}' | sed 's/,//g' >>/tmp/uptime
# cat /tmp/uptime
15:16:59 0.00 0.00 0.00
