  • linux dhcp

    自己记录下,这么几个命令敲了无数遍还错,shit~~~

    /etc/sysconfig/network-scripts/ifcfg-eth0
    DEVICE=eth0
    ONBOOT=yes
    BOOTPROTO=dhcp
    或者使用netconfig配置动态地址
    然后运行# service network restart

  • centos6源及相关

    我想我是能看懂

    # This file uses a new mirrorlist system developed by Lance Davis for CentOS.
    # The mirror system uses the connecting IP address of the client and the
    # update status of each mirror to pick mirrors that are updated to and
    # geographically close to the client. You should use this for CentOS updates
    # unless you are manually picking other mirrors.
    #
    # If the mirrorlist= does not work for you, as a fall back you can try the
    # remarked out baseurl= line instead.

  • zabbix分布式监控1

    闲来无聊研究下分布式监控

    zabbix

    这个东东~·,听说效果不错,看看说明

    http://www.oschina.net/p/zabbix支持snmp管理,也支持自己的agent,

    长相是这样,大家先有个笼统的印象吧

    有个linux必须的我使用的是centos5.6手头有这个,折腾网弄了半天,最后dhclient好了,然后最好先yum upgrade好。悲催的,忘了改源了。

    yum install yum-fastestmirror -y

    希望看到这篇文章的人不要忘了这个。

    1.4和1.6的都有pdf手册,为啥1.8的就要在线看呢,悲剧的。
