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 运行后会出现一个询问菜单，按如下步骤进行回答：CODE:[Copy to clipboard]Do you want to configure the information returned in
