控制節點裝機過程當中的問題

• 現象：sudo apt-get update結果卡在0%[working]

問題緣由：apt-get The method driver /usr/lib/apt/methods/http could not be found

解決辦法：sudo apt-get install apt-transport-https

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

問題緣由： 因爲網絡緣由下載超時致使

問題解決：

$ 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

• 解決安裝devstack時從github下載代碼速度過慢

問題緣由：默認的github下載地址訪問速度慢

問題解決：

$ stackrc 文件中找到GIT_BASE=${GIT_BASE:-git://git.openstack.org} 將這一行的源地址改成https://github.com

• 安裝devstack時pip安裝插件速度慢

問題緣由：默認的pip下載地址訪問速度慢

問題解決：

找到pip.conf文件，沒有的話在根目錄下建立.pip目錄，建立pip.conf,並寫入
$ sudo find -name pip.conf

修改該文件：
[global]

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

trusted-host=pypi.douban.com

• horizon版本與tacker-horizon版本不匹配

問題描述：
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

問題緣由：openstack tacker devstack的bug，在stable/pike版本的devstack中配置文件要求下載master版的tacker-horizon。致使版本不匹配。

問題解決：
以複製一份tacker項目源碼暫時替換，具體就是將原先local.conf配置文件中tacker項目的下載地址改成：enable_plugin tacker https://gitee.com/SINET_gangliu/tacker stable/pike

• pip 安裝軟件出錯

問題描述：
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).

問題緣由：
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.

問題解決：
修改/opt/stack/devstack/inc/python文件，替換上述代碼爲：
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

問題解決：

參考依賴庫版本衝突問題解決方法，並刪除/opt/stack/目錄下的glance文件夾

• 數據庫鏈接出錯

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


問題緣由：
數據庫mysql沒有初始化root密碼，或者初始化root密碼不成功；

問題解決：

重置密碼的第一步就是跳過MySQL的密碼認證過程，方法以下：

#vim /etc/my.cnf

在文檔內搜索mysqld定位到[mysqld]文本段：
/mysqld(在vim編輯狀態下直接輸入該命令可搜索文本內容)

在[mysqld]後面任意一行添加「skip-grant-tables」用來跳過密碼驗證的過程，以下圖所示：

保存文檔並退出：

#:wq
2.接下來咱們須要重啓MySQL：

/etc/init.d/mysql restart(有些用戶可能須要使用/etc/init.d/mysqld restart)


3.重啓以後輸入#mysql便可進入mysql。


4.接下來就是用sql來修改root的密碼

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

到這裏root帳戶就已經重置成新的密碼了。

5.編輯my.cnf,去掉剛纔添加的內容，而後重啓MySQL。

問題緣由：
tacker項目配置文件bug，Remove tacker horizon from lib installation


問題解決：

修改/opt/stack/tacker//devstack/settings 文件，下面展現的文件修改先後對比：

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

31        BR_MGMT=${BR_MGMT:-br-mgmt0}    

修改後：
24        enable_service tacker
25        # enable tacker-conductor will make systemctl enable conductor service
26        enable_service tacker-conductor
27
