ubuntu server 12.04 LTS的安装要点

1，ubuntu server安装过程中选择Openssh Server和LAMP(包含了MYSQL，APACHE和PHP)两个安装包选项
2，安装完毕后，为了加快用apt-get进行安装包的速度，修改apt的源列表文件：
     cd /etc/apt
     cp source.list  source.list.us
     vim source.list  
     采用163的镜像源，如下：
      deb http://mirrors.163.com/ubuntu/ precise main restricted
      deb-src http://mirrors.163.com/ubuntu/ precise main restricted
      deb http://mirrors.163.com/ubuntu/ precise-updates main restricted
      deb-src http://mirrors.163.com/ubuntu/ precise-updates main restricted
      deb http://mirrors.163.com/ubuntu/ precise universe
      deb-src http://mirrors.163.com/ubuntu/ precise universe
      deb http://mirrors.163.com/ubuntu/ precise-updates universe
      deb-src http://mirrors.163.com/ubuntu/ precise-updates universe
      deb http://mirrors.163.com/ubuntu/ precise multiverse
      deb-src http://mirrors.163.com/ubuntu/ precise multiverse
      deb http://mirrors.163.com/ubuntu/ precise-updates multiverse
      deb-src http://mirrors.163.com/ubuntu/ precise-updates multiverse
      deb http://mirrors.163.com/ubuntu/ precise-backports main restricted universe multiverse
      deb-src http://mirrors.163.com/ubuntu/ precise-backports main restricted universe multiverse
      deb http://mirrors.163.com/ubuntu/ precise-security main restricted
      deb-src http://mirrors.163.com/ubuntu/ precise-security main restricted
      deb http://mirrors.163.com/ubuntu/ precise-security universe
      deb-src http://mirrors.163.com/ubuntu/ precise-security universe
      deb http://mirrors.163.com/ubuntu/ precise-security multiverse
      deb-src http://mirrors.163.com/ubuntu/ precise-security multiverse
      deb http://extras.ubuntu.com/ubuntu precise main
      deb-src http://extras.ubuntu.com/ubuntu precise main
3，apt-get update,此时如果报如下错误：
     W: GPG error: http://extras.ubuntu.com precise Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 16126D3A3E5C1192
      解决办法如下：
       apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 16126D3A3E5C1192
      成功后，再执行一次apt-get update
4，安装C/C++开发环境
    sudo apt-get install build-essential //安装主要编译工具 gcc, g++, make
    sudo apt-get install autoconf automake
    sudo apt-get install flex bison
    sudo apt-get install binutils-doc cpp-doc gcc-doc glibc-doc stl-manual //安装相关文档
5，安装memcached和PHP的客户端
    sudo apt-get install memcached php5-memcache
   /etc/init.d/apache2 restart
