cacti yum搭建

#yum install httpd php php-mysql php-snmp mysql mysql-server net-snmp net-snmp-utils rrdtool rrttool-php cacti

#chkconfig mysqld on

#service  mysqld start

#mysqladmin -uroot password 'mypasswd'

#mysqladmin -u root -p create cacti

#mysql -uroot -p cacti < /usr/share/doc/cacti-0.8.8b/cacti.sql            (cacti是自己安装的版本）

#mysql -uroot -p mysql    (输入前面设置的密码 mypasswd)

mysql> grant all on cacti.* to cacti@localhost identified by 'cactipassword' ；     (进入mysql后，提示变成了mysql，这里创建一个                                      cacti的用户，设定密码为cactipassword,另外一个，最后面的“；”一定不能少)

mysql> flush privileges;   (刷新权限，同样的“；”不能少）

mysql> \q   (退出）

#vi /usr/share/cacti/include/config.php

$database_type = "mysql"; $database_default = "cacti"; $database_hostname = "127.0.0.1"; $database_username = "cacti"; $database_password = "cactipassword"; $database_port = "3306"; $database_ssl = false;

保存后退出

#crontab -e -u cacti

*/5 * * * *  php /usr/share/cacti/poller.php > /dev/null 2>&1

保存退出

#vi /etc/httpd/conf.d/cacti.conf

Alias /cacti /usr/share/cacti <Directory /usr/share/cacti/> Order Deny,Allow Alow from all </Directory>

保存退出

#vi /etc/snmp/snmpd.conf

access notConfigGroup "" any noauth exact all none none

view all included .1 80

第一个是改倒数三个单词，第一行是去掉#，然后保存退出

#chkconfig httpd on

#chkconfig snmpd on

#chkconfig snmptrapd on

#service mysqld restart

#service httpd start

#service snmpd start

#service snmptrapd start

#vi /etc/sysconfig/iptables

-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT -A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT -A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT -A INPUT -m state --state NEW -m tcp -p udp --dport 161 -j ACCEPT -A INPUT -m state --state NEW -m tcp -p udp --dport 162 -j ACCEPT

在上面第一行的下面紧接着添加下面几行，保存退出

#service iptables restart

# vi /etc/selinux/config #SELINUX=enforcing #注释掉 #SELINUXTYPE=targeted #注释掉 SELINUX=disabled #增加 :wq 保存，关闭

#shutdown -r now #重启系统

此时cacti已经可以用了。接着就是设置问题了

而被监控机需要添加snmp

#vi /etc/sysconfig/iptables #编辑防火墙配置 -A INPUT -m state --state NEW -m udp -p udp --dport 161 -j ACCEPT

#service iptables restart

#yum -y install net-snmp

#chkconfig snmpd on #设置开机启动 #service snmpd start #启动snmpd

#vi /etc/snmp/snmpd.conf #编辑,修改为下面的内容 com2sec notConfigUser 192.168.100.120 public access notConfigGroup "" any noauth exact all none none view all included .1 80

此至被监控机配置完成
