cacti 监控
cacti监控主机安装# yum install -y epel-release ; yum install -y httpd php php-mysql mysql mysql-server mysql-devel php-gd libjpeg libjpeg-devel libpng libpng-devel ; yum install -y cacti net-snmp net-snmp-utils rrdtool
# vi /etc/httpd/conf.d/cacti.conf
大概22行的位置，把"Deny from all" 改为"Allow from all"
# /etc/init.d/mysqld restart ; /etc/init.d/httpd restart ; /etc/init.d/snmpd restart
# mysql -uroot-e "create database cacti" ; mysql -uroot -e "grant all on cacti.* to 'cacti'@'127.0.0.1'> # vi /usr/share/cacti/include/config.php
# 大概26-32行，修改内容如下
$database_type = "mysql";
$database_default = "cacti";
$database_hostname = "127.0.0.1";
$database_username = "cacti";
$database_password = "cacti";
$database_port = "3306";
$database_ssl = false;
web操作，访问http://192.168.10.29/cacti/，点两下“next”和一次”Finish“ 即可。输入默认用户名admin密码admin 登录，第一次登陆必须重新设置新的密码
# vi /etc/php.ini
date.timezone = 'Asia/Chongqing'
# /usr/bin/php /usr/share/cacti/poller.php
# crontab -e
*/5 * * * */usr/bin/php /usr/share/cacti/poller.php
cacti添加客户端(被监控主机)
# yum install -y net-snmp
# vi /etc/snmp/snmpd.conf
syslocation Unknown (edit /etc/snmp/snmpd.conf)
syscontact Root(configure /etc/snmp/snmp.local.conf)
# 修改为
syslocation 10.39
syscontact Root a945168@163.com
# 另还有两处需要修改
access notConfigGroup "" any noauth exact all none none
view all included .1 80
# /etc/init.d/snmpd start
到cacti主机用 web登陆cacti后台，看图操作

到监控主机上使用命令强制刷新
# /usr/bin/php /usr/share/cacti/poller.php --force
