部署cacti0.8.7g监控网卡流量

监控网络流量cacti

1. 所需软件

RRDTool 1.0.49 or 1.2.x or greater

MySQL 4.1.x or 5.x or greater

PHP 4.3.6 or greater, 5.x greater highly recommended for advanced features

A Web Server e.g. Apache or IIS

 

2. 安装MySQL及php

yum install mysql mysql-server mysql-devel

yum install httpd php php-mysql php-snmp

yum install net-snmp net-snmp-utils net-snmp-devel（需要在被监控的服务器安装并启动）

 

3. 测试SNMP协议

编辑SNMP配置文件

vim /etc/snmp/snmpd.conf

添加

com2sec notConfigUser   localhost     public

测试命令

snmpwalk -v 2c -c public localhost if

 

4. 安装cacti

cacti-0.8.7g

cacti-plugin-0.8.7g-PA-v2.8.tar.gz（插件扩展暂时未装）

cacti-spine-0.8.7g.tar.gz

 

useradd cacti

tar xzvf cacti-0.8.7g.tar.gz

mv cacti-0.8.7g /var/www/html/cacti

chown -R cacti.cacti /var/www/html/cacti

mysqladmin --user=root create cacti

mysql cacti < cacti.sql

 

在MySQL中创建用户cacti

mysql> GRANT ALL ON cacti.* TO cactiuser@localhost IDENTIFIED BY 'cacti';

mysql> flush privileges;

5. 修改配置文件include/config.php和include/global.php

$database_type = "mysql";

$database_default = "cacti";

$database_hostname = "localhost";

$database_username = "cacti";

$database_password = "cacti";

$database_port = "3306";

 

6. 定时任务（crontab -u cacti -e）

*/5 * * * * /usr/bin/php /var/www/html/cacti/poller.php > /dev/null 2>&1

7. 安装spine

版本 cacti-spine-0.8.7g.tar.gz

yum install net-snmp net-snmp-utils net-snmp-devel

./configure

make

make install

测试可用性

# /usr/local/spine/bin/spine

SPINE: Using spine config file [../etc/spine.conf]

SPINE: Version 0.8.7g starting

SPINE: Time: 0.1286 s, Threads: 1, Hosts: 3

不指定路径安装后在/usr/local/spine目录下

 

8. 重构rra文件的目录结构（优化部分）
1. 在crontab里暂停poller.php
2. 然后执行cli目录下的structure_rra_paths.php

/usr/bin/php structure_rra_paths.php --proceed

它会将所有的RRD文件按照device重新分配目录

3. 修改数据库中的RRD路径

Settings—>Paths

4. 恢复poller.php的crontab
