运行./stack.sh，用root不行；创建一个非root用户

DevStack should be run as a user with sudo permissions,
not root.
A "stack" user configured correctly can be created with:
 /root/devstack/tools/create-stack-user.sh

root@ecs-os:~/devstack# tools/create-stack-user.sh
[Call Trace]

之前建立了local.conf文件，写入了一些配置
root@ecs-os:~/devstack# cat local.conf

[[local|localrc]]
ADMIN_PASSWORD=1qaz@WSX
DATABASE_PASSWORD=$ADMIN_PASSWORD
RABBIT_PASSWORD=$ADMIN_PASSWORD
SERVICE_PASSWORD=$ADMIN_PASSWORD
HOST_IP=10.0.0.92
SERVICE_HOST=10.0.0.92

不知道为什么建用户时的local.conf里的HOST_IP没有发生效果

运行./stack.sh，卡在网络上
+functions-common:git_timed:726            timeout -s SIGINT 0 git clone https://opendev.org/openstack/requirements.git /opt/stack/requirements --branch master

通过设置镜像环境变量来解决
export GIT_BASE=https://github.com

然后是报错
+inc/python:pip_install:190                sudo -H LC_ALL=en_US.UTF-8 SETUPTOOLS_USE_DISTUTILS=stdlib http_proxy= https_proxy= no_proxy= PIP_FIND_LINKS= python3.8 -m pip install -c /opt/stack/requirements/upper-constraints.txt -U os-testr

添加阿里Python镜像搞定
stack@ecs-os:~$ cat .pip/pip.conf
[global]
index-url = https://mirrors.aliyun.com/pypi/simple
trusted-host = mirrors.aliyun.com
timeout = 120
stack@ecs-os:~$ pip install pbr==5.11.1  #华为的镜像老一些，最新版本只到5.10.0

问题是，./stack.sh安装没有使用python镜像，做如下配置，你觉得可以解决吗？

export PIP_GET_PIP_URL=https://mirrors.aliyun.com/pip/get-pip.py
export PIP_INDEX_URL=https://mirrors.aliyun.com/pypi/simple/

然后下载11M的 files/etcd-v3.3.12-linux-amd64.tar.gz 慢的要死，手工下载下来核对sha256sum正确

接下来，仍然没有从Python镜像下载
+inc/python:pip_install:190                sudo -H LC_ALL=en_US.UTF-8 SETUPTOOLS_USE_DISTUTILS=stdlib http_proxy= https_proxy= no_proxy= PIP_FIND_LINKS= python3.8 -m pip install -c /opt/stack/requirements/upper-constraints.txt etcd3

破案了，在root用户目录下添加.pip/pip.conf的配置即可，因为上面的sudo -H是会切换到root用户的HOME执行的
所以仅仅在stack用户目录下添加python镜像是没有用的

接下来到了安装openstack的多个服务
+lib/stack:stack_install_service:20 local service=cinder
会很慢，配置使用镜像，在local.conf里添加以下就快了
# use TryStack git mirror
GIT_BASE=http://git.trystack.cn
NOVNC_REPO=http://git.trystack.cn/kanaka/noVNC.git
SPICE_REPO=http://git.trystack.cn/git/spice/spice-html5.git

git了不少项目下来：

stack@ecs-os:~$ sudo du -sm */
1       async/
34      bin/
11      bindep-venv/
123     data/
27      glance/
251     horizon/
46      keystone/

137     neutron/
233     nova/
12      novnc/
22      placement/
33      requirements/
112     tempest/
好像少了点，比如cinder记得有个目录的，怎么后来又没有了
123     cinder/

接下来连接Mysql尝试10次失败并结束

+lib/keystone:init_keystone:489            /usr/local/bin/keystone-manage --config-file /etc/keystone/keystone.conf db_sync
INFO dbcounter [-] Registered counter for database keystone
WARNING oslo_db.sqlalchemy.engines [-] SQL connection failed. 10 attempts left.: oslo_db.exception.DBConnectionError: (pymysql.err.OperationalError) (2003, "Can't connect to MySQL server on 'WSX@127.0.0.1' ([Errno -2] Name or service not known)")

看到WSX，怀疑和local.conf里配置的有关
ADMIN_PASSWORD=1qaz@WSX

于是修改为
ADMIN_PASSWORD=Pass1234

报错：

+lib/databases/mysql:configure_database_mysql:108  sudo mysqladmin -u root password Pass1234
mysqladmin: connect to server at 'localhost' failed
error: 'Access denied for user 'root'@'localhost' (using password: NO)'
+lib/databases/mysql:configure_database_mysql:108  true

改不了密码，因为不是初始的没有密码的状态了。
sudo mysqladmin -u root password Pass1234

参考一下这块代码的注释
# Set the root password - only works the first time. For Ubuntu, we already
# did that with debconf before installing the package, but we still try,
# because the package might have been installed already.

手工修改密码
sudo mysqladmin -u root -p password Pass1234

又添加了些配置到local.conf
# Define images to be automatically downloaded during the DevStack built process.
DOWNLOAD_DEFAULT_IMAGES=False
IMAGE_URLS=http://download.cirros-cloud.net/0.3.4/cirros-0.3.4-x86_64-disk.img

# only support IP v4
SERVICE_IP_VERSION=4

再次执行终于成功
