Ubuntu自动修改为本地源脚本

搭建好本地源后，如果要一台台去修改sources.list文件比较麻烦，于是就整理了个脚本，只需要在VM上运行脚本即可更改成本地源。

下面脚本可以自动识别Ubuntu是12.04还是14.04版本，添加不同版本的源

#!/bin/bash

ARCH=`/usr/bin/getconf LONG_BIT`
REPOD="/etc/apt"
OSVER=`/usr/bin/lsb_release -a |grep Codename |awk -F " " '{print $2}'`
if [ "$(ls -A $REPOD)" ] ; then
[ -d ${REPOD}/sources.list.old ] || /bin/mkdir ${REPOD}/sources.list.old
/bin/mv ${REPOD}/sources.list ${REPOD}/sources.list.old/ -f
fi

if [ ${ARCH}x == 64x -a ${OSVER} == precise ] ; then
/bin/cat >${REPOD}/sources.list <<EOF
deb http://xx.xx.xx.xx/ubuntu precise main multiverse restricted universe
deb http://xx.xx.xx.xx/ubuntu precise-backports main multiverse restricted universe
deb http://xx.xx.xx.xx/ubuntu precise-proposed main multiverse restricted universe
deb http://xx.xx.xx.xx/ubuntu precise-updates main multiverse restricted universe
deb http://xx.xx.xx.xx/ubuntu precise-security main multiverse restricted universe
EOF
elif [ ${ARCH}x == 64x -a ${OSVER} == trusty ] ; then
/bin/cat >${REPOD}/sources.list <<EOF

else
echo "only support Ubuntu-trusty/precise.x86_64"
exit 1
