# linux部署python及虚拟环境 #

## 安装python ##

### 方法一：yum直接安装 ###

`yum install python3 -y`

### 方法二.官方下载源码安装 ###

wget https://www.python.org/ftp/python/3.7.1/Python-3.7.1.tar.xz
    tar xf Python-3.7.1.tar.xz
    cd Python-3.7.1
    yum -y install gcc-* openssl-* libffidevel sqlite-devel
    ./configure --enable-optimizations --with-openssl=/usr/bin/openssl
    make -j4
    make install

测试  
直接输入python3

### 升级pip3 ###

`pip install -upgrage pip`

#### 报错SSL: ####

![format_png][]  
vim Modules/Setup  
211行解除注释,再次make & make install  
![format_png 1][]

#### pip3报错： ####

[root@jinzhang ~]# pip3
    Traceback (most recent call last):
      File "/usr/bin/pip3", line 16, in <module>
        sys.exit(main())
    TypeError: 'module' object is not callable

修改：vi /usr/bin/pip3

from pip import __main__
    if __name__ == '__main__':
        sys.argv[0] = re.sub(r'(-script\.pyw?|\.exe)?$', '', sys.argv[0])
        sys.exit(__main__._main())

即可

### pip包管理 ###

#### 装软件 ####

`pip3 install ipython`  
安装ipython

#### 卸载软件 ####

`pip3 uninstall ipython`

## 安装虚拟化工具 ##

因为每个项目所用的插件不一样，或者插件版本不一样，故装上虚拟化  
`pip3 install virtualenv`

### 使用虚拟化环境 ###

`virtualenv -p python3 web`  
创建一个名称web项目python3环境

`source web/bin/activate`  
即可生效环境

在该环境下，即可安装软件和启动项目

// 启动django
    pip3 install django
    django-admin.py startproject myweb django
    python3 manage.py runserver 192.168.10.42:8000

#### django报错:raise ImproperlyConfigured(‘SQLite 3.8.3 or later is required (found %s).’ % Database.sqlite\_version) ####

django降级 降到2.1.8  
`pip3 install django==2.1.8`

#### django报错：DisallowedHost ####

浏览django网站时，网页报错DisallowedHost  
`vim myweb/settings.py`  
修改  
`ALLOWED_HOSTS = ['*']`  
需要用引号引起来
