Linux安装Cacti及搭建lmap环境
激活额外的yum源，安装lmap环境#yum install yum-priorities
#yum –y install mysql mysql-server php-mysql httpd php
#yum –y install php-pdo lm_sensors net-snmp php-snmp
Net-snmp-utils net-snmp-libs net-snmp-devel net-snmp-perl
Perl-Net-Daemon perl-PIRPC perl-DBI Perl-DBD-MySQL
安装rrdtool ，进入rrdtool文件所在文件夹，
Yum install rrdtool* --nogpgcheck
检查rrdtool和net-snmp是否安装成功

#chkconfig mysqld on
#chkconfig httpd on
#service mysqld start
#service httpd start
#service snmpd start
#vi /var/www/html/php.php
内容如下:
打开http://x.x.x.x/php.php，如果看到配置信息，则lmap配置成功。
1， 创建mysql数据库
#mysql –uroot –p
mysql>create database cacti;
mysql>grant all privileges on cacti.* to cactiuser@localhost identified by ‘123456’;
mysql>grant all privileges on cacti.* to cactiuser@localhost identified by ‘123455’;
msyql>flush privileges;
mysql> \q
2， 安装cacti
#tar zxvf cacti-0.8.7g.tar.gz
#mv cacti-0.8.7g /var/www/html/cacti
#cd /var/www/html/cacti
#mysql –uroot –p cacti < cacti.sql
Password:123456
修改配置文件
#vi /var/www/html/cacti/include/config.php
$database_type = “mysql”;
$database_default = “cacti”;
$database_hostname = “localhost”;
$database_username = “cactiuser”;
$database_password = “123456”;
$database_port = “3306”;
添加cacti用户
#useradd cacti –d /var/www/html/cacti –s /bin/false
#chown –R cacti /var/www/html/cacti/rra
#chown –R /var/www/html/cacti/log
或者
#chown –hR cacti /var/www/html/cacti/rra
#chown –hR cacti /var/www/html/cacti/log
#vi /etc/httpd/conf/httpd.conf
在#ServerName www.example.com:80下增加一行
ServerName 127.0.0.1:80
找到AddType application/x-gzip .gz .tgz
在下面添加
AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps
重启httpd服务，让上面的修改生效
#service httpd restart
然后输入http://x.x.x.x/cacti，打开会看到设置界面，
安装完成，登录用户名为admin，密码为admin
#chmod –R 755 /var/www/html/cacti/poller.php
#vi /etc/crontab 最后添加一行
*/5 * * * * cacti /usr/bin/php /var/www/html/cacti/poller.php > /dev/null 2>&1
#/var/www/html/cacti/poller.php
如果报错，在poller.php添加一行
#!/usr/bin/php –q

出现上面这样就OK了，
#service crond restart
修改目录的属主
#chown –R cacti.cacti /var/www/html/cacti/rra /var/www/html/cacti/log
如果监控没有图和数据，执行
#chmod –R 777 /var/www/html/cacti/rra
#chmod –R 777 /var/www/html/cacti/log
