Cacti检测系统快速部署
试验环境:
本机 IP:192.168.1.3 同时安装被检测端和检测端,检测端和被检测端可以分开进行安装,但是我为了方便起见同时都安装在了一台机器上
www.cacti.net/downloads/cacti-0.8.7b.tar.gz
配置被检测端(snmpd)
[root@localhost ~]# cd /media/RHEL_5.5\ i386\ DVD/Server/
[root@localhost Server]# pwd
/media/RHEL_5.5 i386 DVD/Server
[root@localhost Server]# rpm -ivh lm_sensors-2.10.7-9.el5.i386.rpm  
[root@localhost Server]# rpm -ivh net-snmp-5.3.2.2-9.el5.i386.rpm  
[root@localhost Server]#
[root@localhost Server]# vim /etc/snmp/snmpd.conf

41 com2sec notConfigUser   192.168.1.3        publicsvr
62 access   notConfigGroup ""       any        noauth     exact   all none none
85 view all     included   .1                                80 
 
[root@localhost Server]# service snmpd start
启动  snmpd:                                      [确定]
[root@localhost ~]# chkconfig snmpd on
[root@localhost ~]#
--------------------------
配置检测服务器(Cacti)
安装 web 平台及数据库系统、安装 net-snmp-util 软件包:
[root@localhost ~]# yum install httpd.i386
[root@localhost ~]# yum install mysql.i386 mysql-server.i386 mysql-connector-odbc.i386
[root@localhost ~]# yum install php.i386 php-mysql.i386 php-common.i386 php-pdo.i386
[root@localhost ~]# yum install net-snmp-utils
[root@localhost ~]#
[root@localhost ~]# service httpd start
[root@localhost ~]# service mysqld start
[root@localhost ~]# chkconfig httpd on
[root@localhost ~]# chkconfig mysqld on
[root@localhost ~]#
安装 rrdtool 软件包:
[root@localhost tom]# tar xzvf rrdtool-1.2.27.tar.gz 
[root@localhost tom]# cd rrdtool-1.2.27
[root@localhost tom]#
[root@localhost rrdtool-1.2.27]# ./configure --prefix=/usr/local/
[root@localhost rrdtool-1.2.27]# make
[root@localhost rrdtool-1.2.27]# make install
[root@localhost rrdtool-1.2.27]#
安装 Cacti 服务器套件:
[root@localhost ~]# cd /var/www/html/
[root@localhost html]# tar xzvf /home/tom/cacti-0.8.7b-cn-utf8.tar.gz 
[root@localhost html]#
[root@localhost html]# mv cacti-0.8.7b-cn-utf8 cacti
[root@localhost html]# useradd cactiuser
[root@localhost html]# chown -R cactiuser:cactiuser cacti/rra/ cacti/log/
[root@localhost html]#
设置检测数据库:
[root@localhost html]# mysqladmin -u root password "123456"
[root@localhost html]# mysql -u root -p
mysql> CREATE DATABASE cactidb DEFAULT CHARACTER SET utf8;
Query OK, 1 row affected (0.00 sec)
mysql> GRANT all ON cactidb.* TO cactiuser@localhost IDENTIFIED BY '123456';
Query OK, 0 rows affected (0.00 sec)
mysql> quit
[root@localhost html]# mysql -u cactiuser -p cactidb < cacti/cacti.sql 
注:cacti.sql 数据文件在cacti解压的包中,请注意路径!
Enter password:

调整 Cacti 配置文件:
[root@localhost ~]# cd /var/www/html/cacti/
[root@localhost cacti]# vim include/config.php 

$database_type = "mysql";
$database_default = "cactidb";
$database_hostname = "localhost";
$database_username = "cactiuser";
$database_password = "123456";
$database_port = "3306";
$config['url_path'] = "/";

[root@localhost cacti]#
调整httpd服务并重启服务:
[root@localhost ~]# vim /etc/httpd/conf/httpd.conf 

DocumentRoot "/var/www/html/cacti"
DirectoryIndex index.html index.html.var index.php
<Directory "/var/www/html/cacti">
         Options None
         AllowOverride None
         Order allow,deny
         Allow from all
</Directory>

[root@localhost ~]# service httpd restart
[root@localhost ~]#
-----------------------
打开http://192.168.1.3

初始化后,默认登录名:admin,密码:admin(初次登录要改密码,
例如可以修改为 123456)

设置版本和字体路径:
RRDTool默认字体路径
rrdtool v1.2以上版本所使用的Truetype字体路径.
/usr/share/fonts/chinese/TrueType/ukai.ttf
添加被监测的设备或主机:
指定被监测的主机地址等连接参数
指定需要监测的具体项目(CPU占用、内存使用等)
生成监测图像:
根据设置的监测项目创建图像
将图像添加到监测树以方便查看
添加 cron计划任务,以定期采集数据:
以cactiuser 用户身份采集数据
执行命令:php /var/www/html/cacti/poller.php
通过crontab设置每 5分钟采集一次监测数据
查看图形化监测结果:
按日、周、月、年等分别查看监测图像曲线
可以指定时间进行查询
