除了某种原因pip以及一些python包十分难Download外，github上提供的devstack安装方法在debian_7_x86_64环境上，还有一些未知或者已知因素的问题
1：错误信息：
'[' deb = deb ']' + sudo service tgt restart tgt: unrecognized service + exit_trap + local r=1 ++ jobs -p + jobs=13601 + [[ -n 13601 ]] + [[ -n '' ]] + kill_spinner + '[' '!' -z '' ']' + [[ 1 -ne 0 ]] + echo 'Error on exit' Error on exit + [[ -z /opt/stack/logs ]] + /home/stack/devstack/tools/worlddump.py -d /opt/stack/logs World dumping... see /opt/stack/logs/worlddump-2015-06-07-152812.txt for details + exit 1
在debian上很奇怪，tgt并没有添加到service当中，但是有安装，路径为/usr/sbin/tgtd，而安装过程中源代码为
vim lib/cinder 148 if is_ubuntu; then 149 sudo service tgt restart 150 else 151 restart_service tgtd 152 fi
这里就手动将is_ubuntu的分支修改为：
sudo /usr/sbin/tgtd
2：错误信息：

查看了下源码，报错的地方：
1232 # Once neutron agents are started setup initial network elements
1233 if is_service_enabled q-svc && [[ "$NEUTRON_CREATE_INITIAL_NETWORKS" == "True" ]]; then
1234 echo_summary "Creating initial neutron network elements"
~ 1235 create_neutron_initial_network
~ 1236 setup_neutron_debug
~ 1237 fi
错误位置559行：
_neutron_setup_interface_d 555 sudo ip link set br-int up
_neutron_setup_keystone 556 sudo ip link set $PUBLIC_INTERFACE up
_neutron_setup_rootwrap 557 else

create_neutron_accounts 564 fi
create_neutron_cache_dir 565
create_neutron_initial_net 566 if [[ "$IP_VERSION" =~ .*6 ]]; then
这里看起来十分复杂，重新执行了下./stack.sh之后，这里又没有抱错了
3：错误信息：

原因：route的位置为：/sbin/route，而不再系统环境变量path中
stack@commonqa-lihui:~/devstack$ export PATH=$PATH:/sbin stack@commonqa-lihui:~/devstack$ echo $PATH /usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games:/sbin
除此之外，还有一个Error on exit的错误退出，错误代码在：
446 trap exit_trap EXIT
err_trap 447 function exit_trap {
exit_trap 448 local r=$?
kill_spinner 449 jobs=$(jobs -p)
read_password 450 # Only do the kill when we're logging through a process substitution,
spinner 451 # which currently is only to verbose logfile
452 if [[ -n $jobs && -n "$LOGFILE" && "$VERBOSE" == "True" ]]; then
~ 453 echo "exit_trap: cleaning up child processes"
~ 454 kill 2>&1 $jobs
~ 455 fi
~ 456
~ 457 # Kill the last spinner process
~ 458 kill_spinner
~ 459
~ 460 if [[ $r -ne 0 ]]; then
~ 461 echo "Error on exit"
~ 462 if [[ -z $LOGDIR ]]; then
~ 463 $TOP_DIR/tools/worlddump.py
~ 464 else
~ 465 $TOP_DIR/tools/worlddump.py -d $LOGDIR
~ 466 fi
~ 467 fi
~ 468
~ 469 exit $r
~ 470 }
原因$?是上一次的命令，而重新执行脚本的时候，route是存在的，因此route add的$r不为0，导致异常退出
需要手动执行：
root@commonqa-lihui:~# sudo route del -net 10.0.0.0 netmask 255.255.255.0 gw 172.24.4.2 dev br-ex

原因是执行命令报的错：
stack@commonqa-lihui:~/devstack$ sudo ip -6 addr add 2001:db8::2/64 dev br-ex RTNETLINK answers: File exists
需要手动删除：
stack@commonqa-lihui:~$ sudo ip -6 addr del 2001:db8::2/64 dev br-ex
删除后，ifconfig里就会少了这行：
inet6 addr: 2001:db8::2/64 Scope:Global
基本碰到的问题就是这些了，除此之外，一些主要模块nova等，如果git速度慢，可以换个环境git clone，然后再传到安装的机器上，位置为：
/opt/stack/
基本就能正常安装了
