环境：系统ubuntu14.04.5
eth0: 192.168.10.18 可访问外网
eth1: 172.16.1.1 不可访问外网
一：搭建pip本地源
1.首先使用pip下载所有需要的Python包到指定的目录内，比如/python-packages
root@ubuntu:~# mkdir /python-packages
root@ubuntu:~# cd /python-packages
root@ubuntu:/python-packages# pip download -r ~/pip-requires
注1：pip-requires为需要下载的python包列表，如下所示
root@ubuntu:/python-packages# cat ~/pip-requires
# keystone dependencies
pam>=0.1.4
WebOb==1.2.3
eventlet
greenlet
PasteDeploy
paste
routes
sqlalchemy>=0.7.8,<=0.7.9
sqlalchemy-migrate>=0.7.2
passlib
lxml
iso8601>=0.1.4
python-keystoneclient>=0.2.1,<0.3
oslo.config>=1.1.0
注2：如果使用默认的源的话下载很慢，可以换成国内的pypi源，方法如下
root@ubuntu:~# mkdir ~/.pip
root@ubuntu:~# cat ~/.pip/pip.conf
[global]
trusted-host = mirrors.aliyun.com
index-url = http://mirrors.aliyun.com/pypi/simple
2.运行脚本init_local_pip.sh /python-packages ，脚本如下
#!/bin/bash
# set -x
if [ $# -ne 1 ]; then
echo "Usage: $0 packages_dir"
exit 1
fi
[ ! -d $1 ] && echo "sorry,you should provide a directory." && exit 1
dest=$1
if ! echo $dest |grep -q "^/"; then
echo "sorry,please use the absolute path."
exit 1
fi
if ! ls $dest | egrep -q "gz$|zip$"; then
echo "nothing need to do."
exit 0
fi
len_dest=$(expr length $dest)
lastchar_dest=$(expr substr $dest $len_dest $len_dest)
if [ "$lastchar_dest" = "/" ]; then
let "len=$len_dest-1"
dest=$(expr substr $dest 1 $len)
fi
tmpdir=`mktemp`; rm -rf $tmpdir; mkdir -p $tmpdir
for i in `ls $dest/{*.gz,*.zip}`
do
rm -rf $tmpdir/*
cp $i $tmpdir
cd $tmpdir
temp_arch=`ls`
if echo $temp_arch | grep -q gz; then
tar xf $temp_arch
else
unzip $temp_arch
fi
package_name=`ls -l |grep ^d | awk '{print $9}'`
cd $package_name
if ls |grep -q "egg-info"; then
python setup.py egg_info
python setup.py build
cd ..
rm -rf $temp_arch
if echo $temp_arch |grep -q gz; then
tar czf $temp_arch $package_name
else
zip -r $temp_arch $package_name
fi
rm -rf $i
cp $temp_arch $dest/
fi
done
rm -rf $tmpdir
3.安装pypiserver
root@ubuntu:~# pip install pypiserver
4.为了让在系统启动的时候同时启动pypiserver，修改/etc/rc.local
root@ubuntu:~# cat /etc/rc.local |egrep -v "^#|^$"
cd /var/log/pypiserver
nohup pypi-server -p 8080 /python-packages/ &
exit 0
5.创建pypiserver日志所需目录
root@ubuntu:~# mkdir /var/log/pypiserver
6.启动pypiserver
root@ubuntu:~# bash /etc/rc.local
二：测试
1.再打开一个虚拟机，ip设置为172.16.1.2，并指定pip源为172.16.1.1
root@ubuntu:~# cat .pip/pip.conf
[global]
trusted-host = 172.16.1.1
index-url = http://172.16.1.1:8080/simple
2.用pip安装所需python包即可
root@ubuntu:~# pip install -r pip-requires
