Cacti安装一条龙

Installation CACTI:

yum install php php-mysql mysql mysql-server mysql-devel net-snmp net-snmp* rrdtool rrdtool*
useradd -u 104 cactiuser -d /var/www/cacti -s /sbin/nologin
cd /var/www
tar zxvf cacti-0.8.6j.tar.gz
mv cacti-0.8.6j cacti
chown -R root:root cacti
chown -R cactiuser /var/www/cacti/rra
chown -R cactiuser /var/www/cacti/log
mysql> GRANT ALL on cacti.* to cactiuser@localhost identified by 'cactiuser';
mysql> flush privileges
mysql> create database cacti
mysql -u cactiuser -p cacti < /var/www/cacti/cacti.sql
crontab -e
#
# CACTI
#
*/5 * * * * php /var/www/cacti/poller.php > /dev/null 2>&1
- 本来应该不要以root权限执行
  */5 * * * * cactiuser php /var/www/cacti/poller.php > /dev/null 2>&1)
  但如果你会用到ping的功能. 目前cacti中lib/ping.php, 我还无法解决非root如何执行, 所以直接用root执行
  如果你没用到任何plugin, 其实就用cactiuser去执行crontab, 但如果这样... 那要改/etc/passwd中cactiuser由/sbin/nologin改为/bin/bash
Edit /etc/logrotate.d/cacti
/var/www/cacti/log/cacti.log {
daily
rotate 8
create 0644 cactiuser cactiuser
}
Edit /var/www/cacti/include/config.php
$database_default = "cacti"
$database_hostname = "localhost"
$database_username = "cactiuser"
$database_password = "cacti"
Edit /etc/http/conf.d/cacti.conf
<VirtualHost *:80>
ServerAdmin tommy@ttn.com.tw
DocumentRoot /var/www/cacti
ServerName ncccacti1.ttn.net
</VirtualHost>
http://ncccacti1.ttn.net/
ID: admin
pw: admin

Installation Plugins Architecture:

不论有没用得到Plugins, 我建议一开始还没用前就先装, 不要使用后才开始做, 因为他需要改变一些Files, 一开始做若有问题, 要处理就比较容易:

download [Plugin Architecture Zip]
cd /usr/local/src
mkdir mkdir cacti-plugin
cd cacti-plugin
unzip cacti-plugin-arch.zip
cd /var/www/cacti
patch -p1 -N < /usr/local/src/cacti-plugin/cacti-plugin-0.8.6j.diff
(因为我是0.8.6j, 如果是不同版本就要选不同的)
Modified /var/www/cacti/include/config.php
- check 之前设定没改掉
  $database_default = "cacti"
  $database_hostname = "localhost"
  $database_username = "cactiuser"
  $database_password = "cacti"
- 修改url_path:
  $config['url_path'] = '/';

下面开始安装一些scripts/plugins等五四三:

Install Advance Ping:

安装高级的ping功能模块

Install Monitor Plugin:

安装监视插件功能模块

至http://cactiusers.org/downloads download monitor
cd /var/www/cacti/plugins
mkdir monitor
cd monitor
unzip /root/monitor-0.7.zip
cd ..
chown -R root:root monitor/
modify /var/www/cacti/include/config.php
$plugins = array();
$plugins[] = 'monitor';

Install Discovery:

安装扫描发现功能模块

至http://cactiusers.org/downloads download discovery
mkdir /var/www/cacti/plugins/discovery
cd /var/www/cacti/plugins/discovery
unzip /root/discovery-0.7.zip
mysql -u cactiuser -p cacti < discover.sql
chown -R root:root discovery/
modify /var/www/cacti/include/config.php
$plugins = array();
$plugins[] = 'discovery';
参考http://cactiusers.org/wiki/DiscoverDocs 相关资料
设定
- Console 右边Configuration下的Settings进入Console -> Cacti Settings
- 选Misc
- 至Console -> User Management, 设定User使用权限
Trouble Shooting:
- cd /var/www/cacti/plugins/discovery
- 执行 php -q findhosts.php -f -d

Install Network Weathermap:

安装网络气象图

至http://www.network-weathermap.com/download download
参考: http://www.network-weathermap.com/manual/latest/pages/install-cacti-editor.html
cd /var/www/cacti/plugins
unzip /root/php-weathermap-0.92.zip
chown -R root:root weathermap/
cd weathermap
chown -R cactiuser:apache output/
chmod -R g+w output/
Edit /var/www/cacti/include/config.php
$plugins[] = 'weathermap';
至Console -> User Management, 设定User使用权限

设定Editor
- cd /var/www/cacti/plugins/weathermap
  cp editor-config.php-dist editor-config.php
- Eidt editor-config.php
  $cacti_base = "/var/www/cacti"

设定完后可以至http://your.server/plugins/weathermap/editor.php进行编辑
把要监控的weathermap加入
- 至Console -> Weathermaps
- 按Add加入Config File
- 若点选"Recalculate All Maps Now", 则会立即产生Weahtermaps

Install Cisco Memory Usage Template:

选择cacti_graph_template_cisco_memory_usage.xml所在路径

建立自己的Data Query:
ex: 希望图上都要显示ifAlias

至Console右边Collection Methods下Data Queries: 点选"Snmp - Interface Statistics"
- 点选In/Out Bits
- 至Graph Template - Interface - Traffic (bits/sec)下
  输入|host_description| - Traffic - |query_ifName| - |query_ifAlias|
  Fild Name: Titme

建立自己的Host Template

Start to Add Device:

Console -> Devices: Add
设定Detail
create
Add Associated Graph Templates: EX: 加"Cisco - CPU Usage", "PING - Advanced Ping v1.3"

Authentication with AD:

至Console右边Configuration下的Settings, 然后点选Authentication
建立GuestLDAP的Template
- Console -> User Management: 点选Add
- 修改"Graph Permissions"权限

结论:

CACTI是一个很强的看流量工具, 但因为很强所以很复杂, 如果只是单纯看cisco router/switch, 我建议就用MRTG, 别找麻烦. CACTI要用的好, 就要好好研究... 目前我觉得我的掌握度也只到七成.

其实最强最好, 不代就就最适合你...
