安装cacti被监控主机始终处于Unknown状态；在服务器端输入 提示错误；
cacti]# php poller.php
FATAL: Cannot connect to mysql server on 'localhost'. Please make sure you have specified a valid MySQL database name in 'include/config.php'
rra/下面没有图像，权限755 执行上面的命令提示错误怎么回事？

参考技术A #mysql -u root -p
Password:
# mysql>create database cacti;
# mysql>grant all on cacti.* to cacti@localhost identified by ‘cacti’;
修改cacti使之可以访问数据库
#vim /usr/local/cacti/include/config.php
# $database_type = "mysql";
#$database_default = "cacti";
#$database_hostname = "localhost";
#$database_username = "cacti";
#$database_password = "cacti";
#$database_port = "3306";
导入数据库文件
#mysql -u root -p cacti < cacti.sql 参考技术B 连上数据库再说吧
把include/config.php里面的localhost改为ip地址
try

Cacti添加主机

用户名：root              密码：CactiEZ

yum groupinstall "Development Tools"
yum groupinstall "Compatibility Libraries"

被监控端安装snmp
yum -y install net-snmp net-snmp-devel

被监控端安装配置snmp
vim /etc/snmp/snmpd.conf

com2sec notConfigUser default public
改为 ( cacti主机IP地址 )
com2sec notConfigUser 192.168.0.64 public

access notConfigGroup "" any noauth exact systemview none none
改为
access notConfigGroup "" any noauth exact all none none

#view all included .1 80   
将#注释删掉
view all included .1 80

然后开启 snmp
service snmpd start
service snmpd reload
service snmpd restart

设置snmpd开机启动
chkconfig snmpd on

cacti服务端测试被监控端
snmpwalk -c public -v 2c 192.168.0.64

若检测不成
vi /etc/snmp/snmpd.conf
最后配置如下：
syslocation Server Room
syscontact Sysadmin ([email protected])
rocommunity public 127.0.0.1
agentaddress 161
rocommunity public
rwcommunity private
trapsink 192.168.0.150 public 162 --> 这里的ip=192.168.0.150为被监控主机ip
然后，再执行第二步操作即可。

添加windows需要注意的地方（接受任何主机的snmp数据包）
