一、安装配置依赖包。
[root@cacti ~]# yum -y install httpd php php-mysql mysql-server perl-DBD-MySQL php-pdo net-snmp* ruby ruby-devel [root@cacti ~]# chkconfig httpd on [root@cacti ~]# chkconfig mysqld on [root@cacti ~]# vim /etc/snmp/snmpd.conf access notConfigGroup "" any noauth exact all none none view all included .1 80 [root@cacti ~]# chkconfig snmpd on
二、安装RRDTool，Cacti
[root@cacti ~]# yum -y install rrdtool [root@cacti tmp]# tar -zxvf cacti-0.8.8b.tar.gz -C /var/www/html/ [root@cacti tmp]# cd /var/www/html/ [root@cacti html]# mv cacti-0.8.8b cacti [root@cacti html]# chown -R root:root cacti [root@cacti html]# mysqladmin -u root password 123456 [root@cacti html]# mysql -u root -p Enter password: mysql> create database cacti; mysql> grant all privileges on cacti.* to cacti@localhost identified by 'cacti'; mysql> grant all privileges on cacti.* to cacti@127.0.0.1 identified by 'cacti'; mysql> flush privileges; #重载mysql授权表 mysql> quit [root@cacti html]# crontab -e */1 * * * * php /var/www/html/cacti/poller.php > /dev/null 2>&1 [root@cacti html]# useradd cacti [root@cacti html]# echo "cacti" |passwd --stdin cacti [root@cacti html]# mysql -u cacti -p cacti < /var/www/html/cacti/cacti.sql [root@cacti ~]# vim /var/www/html/cacti/include/config.php $database_type = "mysql"; $database_default = "cacti"; $database_hostname = "localhost"; $database_username = "cacti"; $database_password = "cacti"; $database_port = "3306"; $database_ssl = false;
三、修改cacti管理密码，修改mysql账号密码。
[root@localhsot]# mysql -u root -p
mysql> show databases;
mysql> use cacti;
mysql> show tables;
mysql> select from user_auth;
mysql> update user_auth set password=md5("cactipasswd") where id='1';
################################
[root@localhsot]# service mysqld stop
[root@localhsot]# mysqld_safe --skip-grant-tables &
[root@localhsot]# mysql -u root
mysql> use mysql;
mysql> update user set password=PASSWORD("NEW-ROOT-PASSWORD") where User='root';
mysql> flush privileges;
mysql> quit
[root@localhsot]# service mysqld restart
