1、安装net-snmp

yum install net-snmp net-snmp-libs net-snmp-utils

2、配置net-snmp

修改：

view systemview included .1.3.6.1.2.1.1

为：

view systemview included .1.3.6.1.2.1

3、测试net-snmp

# service snmpd start

# snmpwalk -v 1 -c public localhost .1.3.6.1.2.1.1.1.0

SNMPv2-MIB::sysDescr.0 = STRING: Linux cronos 2.4.28 #2 SMP ven jan 14 14:12:01 CET 2005 i686

yum install httpd php php-mysql php-snmp php-xml php-gd mysql mysql-server

service httpd start

service mysqld start

mysqladmin -uroot password yourpassword

mysqladmin --user=root --password reload

1、下载cacti

cd /tmp

wget http://www.cacti.net/downloads/cacti-0.8.8a.tar.gz

tar xzf cacti-0.8.8a.tar.gz

mv cacti-0.8.8a /var/www/html/cacti

cd /var/www/html/cacti

2、创建数据库

mysqladmin --user=root -p create cacti

3、导入数据库

mysql -uroot -p cacti < cacti.sql

4、创建数据库用户

shell> mysql -uroot -p mysql  (passwd: 123456)

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

mysql> flush privileges;

5、配置include/config.php

$database_type = "mysql";

$database_default = "cacti";

$database_hostname = "localhost";

$database_username = "cactiuser";

$database_password = "cactipassword";

/* load up old style plugins here */

$plugins = array();

//$plugins[] = ‘thold‘;

/*

Edit this to point to the default URL of your Cacti install

ex: if your cacti install as at http://serverip/cacti/ this

would be set to /cacti/

*/

$url_path = "/cacti/";

/* Default session name - Session name must contain alpha characters */

#$cacti_session_name = "Cacti";

6、设置目录权限

chown -R cactiuser rra/ log/

cactiuser为系统存在的用户，为了收集数据。

7、配置计划任务

echo "*/5 * * * * cactiuser php /var/www/html/cacti/poller.php > /dev/null 2>&1">>/etc/crontab

service crond restart

8、完成cacti的安装

1) 在浏览器中输入：http://www.yourdomain. com/cacti/

默认用户名：admin 密码：admin

2) 更改密码

3）设置cacti用到的命令路径

 

 1034  sh restart
 1035  ping localhost
 1036  gvim /var/www/html/cacti/include//config.php
 1037  mysqladmin --user=root -p create cacti
 1038  mysql -uroot -p cacti < cacti.sql
 1039  cd /var/www/html/cacti/
 1040  mysql -uroot -p cacti < cacti.sql
 1041  mysql -uroot -p mysql  
 1042  sh ~/restart
 1043  chown -R cactiuser rra/ log/
 1044  useradd cactiuser
 1045  passwd cactiuser
 1046  chown -R cactiuser rra/ log/
 1047  ls
 1048  gvim include/auth.php
 1049  echo "*/5 * * * * cactiuser php /var/www/html/cacti/poller.php > /dev/null 2>&1">>/etc/crontab
 1050  service crond restart
 1051  gvim include/global_constants.php
 1052  gvim /etc/php.ini
 1053  sh ~/restart
 1054  history

 

warning: strtotime(): It is not safe to rely on the system‘s timezone settings
出现这个错误的原因，主要是因为php.ini里面的时区没有进行设置，可以设置一下，例如：
vi /etc/php.ini
然后找到timezone
将时区设为，例如：Asia/Shanghai
