devstack安装openstack

devstack安装步骤：destack Q版环境；OS配置
============================================================================
destack Q版环境：
    安装包：ubuntu-16.04.7-desktop-amd64.iso
    VMware版本：16
    root@ubuntu:~# uname -a
    Linux ubuntu 4.15.0-112-generic #113~16.04.1-Ubuntu SMP Fri Jul 10 04:37:08 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
    root@ubuntu:~# cat /proc/version
    Linux version 4.15.0-112-generic (buildd@lcy01-amd64-021) (gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.12)) #113~16.04.1-Ubuntu SMP Fri Jul 10 04:37:08 UTC 2020

-----------------------------------------------------------------------------
OS配置：
    1.安装ssh，并配置允许root远程登录；安装git
            root@ubuntu:~# cat /etc/ssh/sshd_config |grep PermitRootLogin
            PermitRootLogin yes

            systemctl restart sshd.service    ---重启SSH服务
            
            apt-get install git
    2.修改网卡配置
            root@ubuntu:~# cat /etc/network/interfaces
            auto lo
            iface lo inet loopback

            auto ens33
            iface ens33 inet static
            address 192.168.1.51
            netmask 255.255.255.0
            gateway 192.168.1.1
            dns-nameserver 192.168.1.1


            /etc/init.d/networking restart
            systemctl restart networking.service    ---重启网络服务

    3.修改apt源
            root@ubuntu:~# cat /etc/apt/sources.list
            deb http://mirrors.163.com/ubuntu/ xenial main restricted universe multiverse
            deb http://mirrors.163.com/ubuntu/ xenial-security main restricted universe multiverse
            deb http://mirrors.163.com/ubuntu/ xenial-updates main restricted universe multiverse
            deb http://mirrors.163.com/ubuntu/ xenial-proposed main restricted universe multiverse
            deb http://mirrors.163.com/ubuntu/ xenial-backports main restricted universe multiverse
            deb-src http://mirrors.163.com/ubuntu/ xenial main restricted universe multiverse
            deb-src http://mirrors.163.com/ubuntu/ xenial-security main restricted universe multiverse
            deb-src http://mirrors.163.com/ubuntu/ xenial-updates main restricted universe multiverse
            deb-src http://mirrors.163.com/ubuntu/ xenial-proposed main restricted universe multiverse
            deb-src http://mirrors.163.com/ubuntu/ xenial-backports main restricted universe multiverse
    apt-get update
    apt-get upgrade

devstack安装步骤：destack Q版环境；OS配置

devstack安装步骤:部署openstack;pip.conf配置；
---------------------------------------------------------------------------------------------
部署openstack
    apt install python-pip      #安装pip
    下载devstack
        git clone https://git.openstack.org/openstack-dev/devstack -b stable/newton
        实际采用的方法为登录上述链接，选取相应的分支，下载zip文件；然后手工上传到ubuntu；最后unzip
    创建stack用户
        /root/devstack/tools/create-stack-user.sh        ---创建用户
    配置pip，为root用户及stack用户设置国内镜像源
        root用户、stack用户分别执行mkdir ~/.pip&&vim ~/.pip/pip.conf
        
    配置local.conf
    　　mv /root/devstack/ /opt/stack/                ----将root/devstack移动至stack用户目录
    　　chown stack:stack /opt/stack/devstack     -----文件夹权限修改
    　　vim /opt/stack/devstack/local.conf        #######将如下内容粘贴进去

    执行安装脚本
　　  /opt/stack/devstack/stack.sh             ---需N多次执行才可以完成安装

------------------------------------------------------------
pip.conf配置

root@ubuntu:~# cat ~/.pip/pip.conf
[global]
index-url = https://pypi.douban.com/simple
download_cache = ~/.cache/pip
[install]
use-mirrors = true
mirrors = http://pypi.douban.com/

安装心得以及错误处理；出现在安装中断后，重装时碰到的错误；安装日志路径；
=================================================================
安装心得以及错误处理：
    0.提前下载3个文件并放入目录/opt/stack/devstack/files，可以有效提高部署时间
        cirros-0.3.5-x86_64-disk.img、etcd-v3.1.10-linux-amd64.tar.gz、get-pip.py.old-py27
        
    1.大部分devstack脚本与现有环境存在问题，思路就是找到匹配度高的，才能有效减少错误。
        这里通过链接https://git.openstack.org/openstack-dev/devstack，下载了所有版本进行安装测试，最终Q版与当前系统匹配度最高

    2.系统语言修改为英文，否则web登陆时，会碰到编码错误 
    3.python模块版本问题，根据错误提示，修改文件，直接删除了该模块的版本校验
        vim /opt/stack/requirements/upper-constraints.txt

-----------------------------------------------------------------
出现在安装中断后，重装时碰到的错误：
    1.'br-ex'已存在的错误，执行前删除该网桥即可 
        sudo brctl delbr br-ex       

    2.curl -g -k --noproxy '*' -s -o /dev/null -w '%{http_code}' http://192.168.1.61/image    #503错误
        ps -ef |grep stack    #找出相应的glance进程，杀死
        ###关闭进程可能需要进行systemctl stop xxxx；因为单纯的杀死进程，会直接拉起

----------------------------------------------------------------
安装日志路径：
    /opt/stack/logs
