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
