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
#servicemysqld 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
