重启mysql + apache 服务
[root @localhost htdocs]# service mydql restart
[root @localhost htdocs]# service httpd restart
进入浏览器检查
和
安装rrdtool
[root@localhost usr]# tar zxvf rrdtool-1.0.50.tar.gz
[root@localhost usr]# cd rrdtool-1.0.50
[root@localhost rrdtool-1.0.50]# ./configure
[root@localhost rrdtool-1.0.50]# make && make install
我的是fedora 7,用下面的方法。
[root@localhost usr] yum install rrdtool
Rrdtool安装完毕
安装net-snmp、snmpwalk和snmpget命令
[root@localhost usr]# rpm -qa | grep net-snmp
net-snmp-5.0.9-2.30E.15
net-snmp-devel-5.0.9-2.30E.15
net-snmp-libs-5.0.9-2.30E.15
net-snmp-utils-5.0.9-2.30E.15
[root@localhost usr]# vi /etc/snmp/snmpd.conf
更改 1、com2sec notConfigUser default public
改为：com2sec notConfigUser 127.0.0.1 public
2、access notConfigGroup "" any noauth exact systemview none none
改为：access notConfigGroup "" any noauth exact all none none
3、#view all included .1 80
将前面的 # 注释 去掉。
保存退出 :wq
[root@localhost usr]# service snmpd restart
或者使用：net-snmp-5.1.4.tar.gz安装
[root@localhost local]# tar -zxvf net-snmp-5.1.4.tar.gz
[root@localhost local]# cd net-snmp-5.1.4
[root@localhost local]# ./configure
[root@localhost local]# make
[root@localhost local]# make install
运行snmpconf -g basic_setup，会在当前目录下生成一个snmpd.conf配置文件：
[root@localhost local]# snmpconf -g basic_setup
