有线未托管

ubuntu虚拟机桥接模式在/etc/network/interfaces配置静态IP失败的另一种解决方法

网络配置命令：
ifconfig 网卡名 ip地址 ，设置ip地址
ifconfig 网卡名 up ，启动网卡
ifconfig 网卡名 down ，禁用网卡
ifup 网卡名 ，启动网卡
ifdown 网卡名，禁用网卡
ifconfig 网卡名 ip地址 netmask 子网掩码 ，同时设置ip和子网掩码

Netplan配置详解

配置过程

创建节点：控制节点controll与计算节点compute，

  1. 控制节点使用3块网卡：桥接网络、内部网络，以及仅主机
  2. 计算节点使用2块网卡：桥接网络、内部网络

节点的启动

启动节点的第一次，对节点进行安装Ubuntu，具体安装过程如下：

• 创建compute节点

apt换中国内部的软件源

• 查看当前的版本名

修改源之前提示大家先查看版本名，ubuntu20.04对应的是“focal”，也就是我下面镜像源中提到的。“eoan”代表ubuntu19.10，“xenial”代表ubuntu16.04，“bionic”代表ubuntu18.04，“disco”代表ubuntu19.04，但是最好还是查看自己的版本名，并更改相应位置的ubuntu版本名。

lsb_release -c

• 备份原来的软件源并另存

前面是原始文件，后面是备份之后的文件

sudo cp -v /etc/apt/sources.list /etc/apt/sources.list.bak
1

.bak 是 backup 的意思，表示备份文件。

• 执行chmod命令更改文件权限使软件源文件可编辑：

sudo chmod 777 /etc/apt/sources.list
1

• 通过gedit命令或vim编辑软件源：

sudo gedit /etc/apt/sources.list
1

vim /etc/apt/sources.list

在前面加入换源的网址，或者将原始的源直接删除之后再加入还原网址，如阿里云

#deb http://archive.ubuntu.com/ubuntu/ trusty main universe restricted multiverse #一定要在首行，后面可以安装yum

deb http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse

配置静态网卡

第一个网卡设置为静态ip

【注意】：Ubuntu18.04以后修改ip地址是使用netplan所以以下的修改可能会导致连接不了网络。

ip l # 查看网卡信息

iface enp0s3 inet static
address 192.168.43.242
netmask 255.255.255.0

【正确配置Ubuntu20.04网卡的方法如下：】

要按一下的方法，修改配置文件：

cd /etc/netplan/

ls

sudo vim 01-network-manager-all.yaml

ethernets:

dhcp4: no #dhcp4关闭
addresses: [192.168.43.242/24] #设置本机IP及掩码

DevStack安装OpenStack

官方文档

参考：未2-配置环境变量

Ubuntu及OpenStack安装指南（云计算实验用）

ubuntu18.04安装openstack

Ubuntu 20使用devstack快速安装openstack最新版【6.配置环境变量脚本】

ubuntu18.04系统下用devstack安装openstack(最新版)

未1-有些资源要手动下载

CloudMan-ubuntu-16.04.1安装OpenStack

• 用root用户登录到ssh

ssh root@192.168.43.220

• 安装过程中需要使用pip，所以需要确保操作系统中已有pip包

pip

apt install python3-pip

• 将yum源换成华为源

sudo cp -a /etc/apt/sources.list /etc/apt/sources.list.bak
sudo sed -i “s@http://.*archive.ubuntu.com@http://repo.huaweicloud.com@g” /etc/apt/sources.list

• 将PyPI源换成华为源

#新建.pip目录
sudo mkdir .pip

• 设置时区

  • 设定时区：

    sudo dpkg-reconfigure tzdata

    选择Asia -> 在选择Shanghai -> OK

  • 同步时间命令:

sudo apt-get install ntpdate  #安装时间同步工具sudo ntpdate cn.pool.ntp.org # 与网络服务器同步时间date # 查看时间是否已经同步
1

添加stack用户

#新增stack用户
sudo useradd -s /bin/bash -d /opt/stack -m stack
#授予stack用户sudo权限
echo “stack ALL=(ALL) NOPASSWD: ALL” | sudo tee /etc/sudoers.d/stack
#切换到stack用户
sudo su - stack

或者：

/root/devstack/tools/create-stack-user.sh

配置pip源头

mkdir ~/.pip

vim ~/.pip/pip.conf

以下内容粘贴进去

[global]index-url = https://pypi.douban.com/simple/trusted-host = pypi.douban.com#download_cache = ~/.cache/pip[install]use-mirrors = truemirrors = http://pypi.douban.com/

下载devstack

stack用户的pip源也需要换成国内的源，详细参考换root用户的换源过程

#使用git下载devstackgit clone https://opendev.org/openstack/devstack#下载完成后切换到devstack目录下cd devstack

或者下载N版到/root/目录

git clone https://git.openstack.org/openstack-dev/devstack -b stable/newton

• 添加local.conf文件

#在devstack根目录下添加local.conf文件
vim local.conf
#将以下内容添加到local.conf文件中

原因，解决1

【解决方法】：

• FORCE=yes ./stack.sh

  或者把在源码中把die的那一行代码注释了。在重新运行./stack.sh

安装时间比较长，具体要看当前网络，本次安装耗时45分钟，出现以下页面表示已基本完成，等待脚本命令结束即可。

【安装过程错误】解决：

1. 遇到超时错误
   重新运行./stack.sh
2. python2和python3之间的代码冲突

解决，解决2

把出错代码中第三个参数0删去。

3. ModuleNotFoundError: No module named ‘os_testr’

• 修改root用户密码

  MySql 从8.0开始修改密码有了变化，在user表加了字段authentication_string，修改密码前先检查authentication_string是否为空

  • 如果不为空，先置空字段在修改密码

  use mysql;  update user set authentication_string='' where user='root';      #将字段置为空 alter user 'root'@'localhost' identified with mysql_native_password by '123456';     #修改密码为123456
  1

  • 如果为空，则直接修改密码

  alter user 'root'@'localhost' identified with mysql_native_password by '123456';   #修改密码为123456

【注意】有的教程会建议修改数据库配置文件绕过密码登录。会使root用户处于无密码状态，后期修改密码会报一个root处于无密码状态的错误。

解决：方法在后半部分

• 设置允许允许远程连接
  修改配置文件

sudo vim /etc/mysql/mysql.conf.d/mysqld.cnf
1

将bind-address后面的ip地址改为0.0.0.0保存并退出，然后重启mysql服务

service mysql restart
1

远程登录MySQL的设置：

• 使用刚刚修改的密码用root用户进入数据库：

mysql -u root -p

• 设置远程访问：

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%'IDENTIFIED BY '远程访问密码' WITH GRANT OPTION;

其中 ‘root’@’%’ 中的root表示远程访问数据库的账户，%表示所有IP均可访问，'远程访问密码’表示远程访问mysql时需要的密码，此时就完成了mysql开启远程访问的操作。

但是我在使用这句语句的时候报错了：

以上的一行代码这种方法并不适用于Mysql 8.0以后的版本

【解决方法：】

CREATE USER ‘root’@’%’ IDENTIFIED BY ‘你的密码’;
GRANT ALL ON . TO ‘root’@’%’;
ALTER USER ‘root’@’%’ IDENTIFIED WITH mysql_native_password BY ‘你的密码’;

三条命令按顺序执行完成后，刷新权限：

FLUSH PRIVILEGES;

实在安装不了OpenStack

• 在~/stack目录下备份local.conf

  sudo cp local.conf /home/xiao/桌面/local.conf.bak

• ./unstack.sh

• ./clean.sh

• 删除 /opt/stack文件夹

  sudo rm -r /opt/stack

• 删除stack用户

  命令参考：ubuntu创建和删除用户

  ​ ubuntu查看所有用户

  sudo userdel -r stack

  grep bash /etc/passwd # 查看所有用户

• 重新安装

• 或者降低Ubuntu的版本重新再安装

Ubuntu16.04安装OpenStack

根据前面的安装OpenStack步骤做到stack用户运行./stack.sh之前，需要安装Python3.6。

安装Python3.6

cd /usr/local/lib

• 下载安装包

sudo wget http://www.python.org/ftp/python/3.6.4/Python-3.6.4.tgz

• 安装依赖包

sudo apt install libreadline-gplv2-dev libncursesw5-dev libssl-dev libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-dev

• 解压

sudo tar -xvzf Python-3.6.4.tgz

• 创建python3.6文件夹

sudo mkdir /usr/local/python3.6

./configure --prefix=/usr/local/python3.6

configure文件是一个可执行的脚本文件，它有很多选项，在待安装的源码目录下使用命令./configure –help可以输出详细的选项列表。

其中--prefix选项是配置安装目录，如果不配置该选项，安装后可执行文件默认放在/usr /local/bin，库文件默认放在/usr/local/lib，配置文件默认放在/usr/local/etc，其它的资源文件放在/usr /local/share，比较凌乱。

如果配置了--prefix,安装后的所有资源文件都会被放在/usr/local/python3.6目录中，不会分散到其他目录。

使用--prefix选项的另一个好处是方便卸载软件或移植软件

• 当某个安装的软件不再需要时，只须简单的删除该安装目录，就可以把软件卸载干净；
• 移植软件只需拷贝整个目录到另外一个机器即可（相同的操作系统下）

当然要卸载程序，也可以在原来的make目录下用一次make uninstall，但前提是Makefile文件有uninstall命令。

• 编译

make讲解

./configure --enable-optimizations

或者上面两句合成一句

./configure --prefix=/usr/local/python3.6 --enable-optimizations #可执行文件放在/usr /local/python3.6/bin，库文件放在/usr/local/python3.6/lib，配置文件放在/usr/local/python3.6/include，其它的资源文件放在/usr /local/python3.6/share

sudo make #编译，大多数的源代码包都经过这一步进行编译。

只要编译不报错就可以进行安装了。

make test #对上一步 make 的检查了，要确保 make 是没有错误的，也就是这一步的 test、check要全部是 OK 的，error 为0

以下为make编译的出错，解决方案在后面

以下文字摘自官方的README：

On Unix and Mac systems if you intend to install multiple versions of Pythonusing the same installation prefix (``--prefix`` argument to the configurescript) you must take care that your primary python executable is notoverwritten by the installation of a different version.  All files anddirectories installed using ``make altinstall`` contain the major and minorversion and can thus live side-by-side.  ``make install`` also creates``${prefix}/bin/python3`` which refers to ``${prefix}/bin/pythonX.Y``.  If youintend to install multiple versions using the same prefix you must decide whichversion (if any) is your "primary" version.  Install that version using ``makeinstall``.  Install all other versions using ``make altinstall``.For example, if you want to install Python 2.7, 3.5, and 3.6 with 3.6 being theprimary version, you would execute ``make install`` in your 3.6 build directoryand ``make altinstall`` in the others.

• 配置环境变量

若./configure --prefix=/usr/local/python3.6，则需要添加环境变量。
若./configure的无需配置

#添加环境变量

PATH=$PATH:$HOME/bin:/usr/local/python3.6/bin

#查看环境变量

echo $PATH

• 添加到全局环境变量

sudo vim /etc/profile #全局的

#在文末添加下面一行

export PATH=$PATH:/usr/local/python3.6/bin #这个路径是python3.6安装的路径

source /etc/profile #生效配置信息

• 或者添加到当前用户的环境变量

vim .bashrc #自己用户的

export PATH=$PATH:/usr/local/python3.6/bin #这个路径是python3.6安装的路径

source .bashrc #生效配置信息

• 更改默认指向

参考：https://blog.csdn.net/zw05011/article/details/105702318/

由于python3.6是自己安装的，不在/usr/bin下，而在usr/local/bin或者/usr/local/python3.6/bin下（取决于前面执行的./configure还是./configure --prefix=/usr/local/python3.6。因此需要先加一条软链接并且把之前的python命令改为python.bak，同时pip也需要更改。依次执行以下命令。

若python3.6安装时，执行的是./configure --prefix=/usr/local/python3.6，则为：

#备份原链接

mv /usr/bin/python3 /usr/bin/python3.bak

#或者为

mv -f /usr/bin/python3 /usr/bin/python3.bak

#创建新连接，ln -s 原文件 目标文件

ln -s /usr/local/python3.6/bin/python3.6 /usr/bin/python3

#备份原链接

mv /usr/bin/pip3 /usr/bin/pip3.bak

ln -s /usr/local/python3.6/bin/pip3 /usr/bin/pip3

以后用python3.6直接用python3以及pip3

`pip`正在被低版本的python使用，建议使用python时使用`-m pip`取代直接用`pip`

参考：https://github.com/pypa/pip/issues/5599

• 用你的系统包管理器来升级系统 pip。pip install -U pip

• 切勿将 sudo 与 pip 一起使用

• 使用pip时加上--user。

  在您的个人目录中安装软件包，从而避免干扰 pip 的系统副本。
