控制节点装机过程中的问题

现象：sudo apt-get update结果卡在0%[working]

问题原因：apt-get The method driver /usr/lib/apt/methods/http could not be found

解决办法：sudo apt-get install apt-transport-https

/opt/stack/devstack/files/etcd-v3.1.7-linux-amd64.tar.gz: FAILED

问题原因： 由于网络原因下载超时导致

问题解决：

$ cd files/

$ wget -c https://github.com/coreos/etcd/releases/download/v3.1.10/etcd-v3.1.10-linux-amd64.tar.gz
$ wget -c  https://github.com/coreos/etcd/releases/download/v3.1.7/etcd-v3.1.7-linux-amd64.tar.gz

解决安装devstack时从github下载代码速度过慢

问题原因：默认的github下载地址访问速度慢

问题解决：

$ stackrc 文件中找到GIT_BASE=${GIT_BASE:-git://git.openstack.org} 将这一行的源地址改为https://github.com

安装devstack时pip安装插件速度慢

问题原因：默认的pip下载地址访问速度慢

问题解决：

找到pip.conf文件，没有的话在根目录下创建.pip目录，创建pip.conf,并写入
$ sudo find -name pip.conf

修改该文件：
[global]

index-url = http://pypi.douban.com/simple

trusted-host=pypi.douban.com

horizon版本与tacker-horizon版本不匹配

问题描述：
2018-04-14 02:48:12.395 | ContextualVersionConflict: (horizon 12.0.3.dev45 (/opt/stack/horizon), Requirement.parse('horizon>=13.0.0'), set(['tacker-horizon']))
2018-04-14 02:48:12.509 | Error on exit

问题原因：openstack tacker devstack的bug，在stable/pike版本的devstack中配置文件要求下载master版的tacker-horizon。导致版本不匹配。

问题解决：
以复制一份tacker项目源码暂时替换，具体就是将原先local.conf配置文件中tacker项目的下载地址改为：enable_plugin tacker https://gitee.com/SINET_gangliu/tacker stable/pike

pip 安装软件出错

问题描述：
installed pip version 1 does not meet minimum requirements
[ERROR] /opt/stack/devstack/inc/python:146 Currently installed pip version 1 does not meet minimum requirements (>=6).

问题原因：
The code in '/opt/stack/devstack/inc/python' line 142 to 148

local pip_version
    pip_version=$(python -c "import pip; \
                        print(pip.__version__.strip('.')[0])")
    if (( pip_version<6 )); then
        die $LINENO "Currently installed pip version ${pip_version} does not" \
            "meet minimum requirements (>=6)."
    fi

When the pip version >10, the resule of 'pip.__version__.strip('.')[0]' is 1, then the error happen.

问题解决：
修改/opt/stack/devstack/inc/python文件，替换上述代码为：
local pip_version
    pip_version=$(python -c "import pip; \
                        print(pip.__version__.split('.')[0])")
    if (( pip_version<6 )); then
        die $LINENO "Currently installed pip version ${pip_version} does not" \
            "meet minimum requirements (>=6)."
    fi

glance-api无法启动

2018-04-14 04:55:07.876 | /opt/stack/devstack/lib/glance:355:die
2018-04-14 04:55:07.878 | [ERROR] /opt/stack/devstack/lib/glance:355 g-api did not start

问题原因：
oslo.utils 依赖库版本不正确

问题解决：

参考依赖库版本冲突问题解决方法，并删除/opt/stack/目录下的glance文件夹

依赖库版本冲突

问题描述：
2018-04-13 14:57:39.584 |    raise VersionConflict(dist, req).with_context(dependent_req)
2018-04-13 14:57:39.584 | ContextualVersionConflict: (oslo.utils 3.28.2 (/usr/local/lib/python2.7/dist-packages), Requirement.parse('oslo.utils>=3.33.0'), set(['python-barbicanclient']))

问题原因：
2018-04-15 09:56:51.916 | python-barbicanclient 4.6.1.dev8 has requirement keystoneauth1>=3.4.0, but you'll have keystoneauth1 3.1.0 which is incompatible.

所有依赖库的版本信息都写在 /opt/stack/requirements/upper-constraints.txt文件中

问题解决：

修改 /opt/stack/requirements/upper-constraints.txt文件相应依赖库的版本
$ sudo vim  /opt/stack/requirements/upper-constraints.txt

数据库连接出错

问题描述：

2018-04-16 01:52:24.741 | ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)


问题原因：
数据库mysql没有初始化root密码，或者初始化root密码不成功；

问题解决：

重置密码的第一步就是跳过MySQL的密码认证过程，方法如下：

#vim /etc/my.cnf

在文档内搜索mysqld定位到[mysqld]文本段：
/mysqld(在vim编辑状态下直接输入该命令可搜索文本内容)

在[mysqld]后面任意一行添加“skip-grant-tables”用来跳过密码验证的过程，如下图所示：

保存文档并退出：

#:wq
2.接下来我们需要重启MySQL：

/etc/init.d/mysql restart(有些用户可能需要使用/etc/init.d/mysqld restart)


3.重启之后输入#mysql即可进入mysql。


4.接下来就是用sql来修改root的密码

mysql> use mysql;
mysql> update user set authentication_string=PASSWORD("密码") where user='root';
mysql> flush privileges;
mysql> quit

到这里root账户就已经重置成新的密码了。

5.编辑my.cnf,去掉刚才添加的内容，然后重启MySQL。

问题原因：
tacker项目配置文件bug，Remove tacker horizon from lib installation


问题解决：

修改/opt/stack/tacker//devstack/settings 文件，下面展示的文件修改前后对比：

修改前：
24        enable_service tacker    
25        # enable tacker-conductor will make systemctl enable conductor service    
26        enable_service tacker-conductor    
27        # tacker-horizon isn't installable from pip        
28        LIBS_FROM_GIT=tacker-horizon        
29           
30        MGMT_PHYS_NET=${MGMT_PHYS_NET:-mgmtphysnet0}    
31        BR_MGMT=${BR_MGMT:-br-mgmt0}    

修改后：
24        enable_service tacker
25        # enable tacker-conductor will make systemctl enable conductor service
26        enable_service tacker-conductor
27 
28
30        MGMT_PHYS_NET=${MGMT_PHYS_NET:-mgmtphysnet0}
31        BR_MGMT=${BR_MGMT:-br-mgmt0}
