centos安装nginx+php+mysql

一、更改yum源为网易的源加快速度
vi /etc/yum.repos.d/CentOS-Base.repo
更改内容如下
# CentOS-Base.repo
#
# 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.
#

经典dos命令

1.最基本，最常用的，测试物理网络的
ping 192.168.10.59 －t ，参数－t是等待用户去中断测试
2.查看DNS（对猫用户），还是比较有用处的
A.Win98：winipcfg
B.Win2000以上：Ipconfig/all
C.WinNt:CMD，然后NSLOOKUP
3.网络信使
Net send 计算机名/IP 传送内容，注意不能跨网段
net stop messenger 停止信使服务，也可以在面板－服务修改
net start messenger 开始信使服务
4.探测对方对方计算机名，所在的组、域及当前用户名
ping －a IP地址 －t ，只显示NetBios名
nbtstat -a 192.168.10.146 比较全的
5.netstat -a 显示出你的计算机当前所开放的所有端口
netstat -s -e 比较详细的显示你的网络资料，包括TCP、UDP、ICMP 和 IP的统计等
6.探测谁连接了我的计算机
arp -a
7.捆绑IP和MAC解决局域网内盗用IP的问题
ARP －s 192.168.10.59 00－50－ff－6c－08－75
8.在网络邻居上隐藏你的计算机
net config server /hidden:yes
net config server /hidden:no 则为开
