#一、阿里云CentOS7配置 以下以root用户来操作 赋予执行权限！！

    (root)$ chmod +x /root
    

安装系统依赖
------

有Python、MySQL（可选）依赖、Elasticsearch对Java的依赖，Django-compressor的压缩需要的依赖bzip2-devel等

    (root)$ yum -y update
    (root)$ yum install -y install python-devel zlib-devel mysql-devel libffi-devel openssl-devel bzip2-devel ncurses-devel sqlite-devel readline-devel tk-devel java wget gcc make tmux
    

1.3 安装Python3.7.4最新版本
---------------------

    (root)$ wget https://www.python.org/ftp/python/3.7.4/Python-3.7.4.tgz
    
    #编译python
    (root)$ tar -zxvf Python-3.7.4.tgz
    (root)$ cd Python-3.7.4
    (root)$ ./configure --prefix=/usr/local/python3
    (root)$ make&&make install
    
    #添加软连接
    (root)$ ln -s /usr/local/python3/bin/python3 /usr/bin/python3
    (root)$ ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3
    

**注意：加上**`--enable-optimizations`后make的速度非常慢，但是执行Python代码时会有10%-20%的性能提升。

二、安装apache/redis
================

    yum -y install httpd httpd-devel redis
    

启动apache

三、准备工作
======

安装虚拟环境，复制下虚拟环境的路径，exit退出虚拟环境，然后切换到Python3.7的安装包目录，执行以下命令

    ./configure --prefix=/root/.local/share/virtualenvs/zhihu-k2NuTCjv/ --enable-shared
    make && make install
    

注意：Python3.7版本以后都要使用`--enable-shared`的命令。 然后搜索libpython3.7m.so.1.0

    find / -name libpython3.7m.so.1.0
    /root/.local/share/virtualenvs/zhihu-k2NuTCjv/lib/libpython3.7m.so.1.0
    /root/Python-3.7.2/libpython3.7m.so.1.0
    

注意，是虚拟环境的路径。`/root/.local/share/virtualenvs/zhihu-k2NuTCjv/lib/libpython3.7m.so.1.0`复制下来，拷贝到`/usr/lib64/`目录下面

    cp /root/.local/share/virtualenvs/zhihuuTCjv/lib/libpython3.7m.so.1.0 /usr/lib64/
    

此时才能安装`mod_wsgi`第三方包，进入虚拟环境！！

    pipenv shell
    pip3 install mod_wsgi
    mod_wsgi-express install-module
    LoadModule wsgi_module "/usr/lib64/httpd/modules/mod_wsgi-py37.cpython-37m-x86_64-linux-gnu.so"
    WSGIPythonHome "/root/.local/share/virtualenvs/zhihu-k2NuTCjv"
    

修改apache配置

    vim /etc/httpd/conf/httpd.conf
    

搜索Example，在226行加入如下命令

    LoadModule wsgi_module "/usr/lib64/httpd/modules/mod_wsgi-py37.cpython-37m-x86_64-linux-gnu.so"
    

搜索ServerName，改成如下：

此时重启apache服务，使用的Python就会变成3.7版本

配置apache
========

创建文件并编辑

    touch /etc/httpd/conf.d/django.conf
    

django.conf文件如下：

    WSGIPythonHome /root/.local/share/virtualenvs/zhihu-k2NuTCjv
    WSGIPythonPath /root/zhihu
    
    <VirtualHost *:80>
        ServerName localhost
        Alias /static/ /root/zhihu/zhihu/staticfiles/
        Alias /media/ /root/zhihu/zhihu/media/
    
        <Directory /root/zhihu/zhihu/staticfiles>
            Require all granted
        </Directory>
    
        <Directory /root/zhihu/zhihu/media>
            Require all granted
        </Directory>
    
        <Directory /root/zhihu/config>
            <Files wsgi.py>
                Require all granted
            </Files>
        </Directory>
    
        WSGIDaemonProcess zhihu python-path=/root/.local/share/virtualenvs/zhihu-k2NuTCjv
        WSGIScriptAlias / /root/zhihu/config/wsgi.py
    
    </VirtualHost>
    

保存后重启，部署成功！
