阿里云服务器 debian9 apache2 部署flask+wsgi 过程总结

由于阿里云镜像自带的源更新比较缓慢，最新的python3版本还是3.5，而我的代码使用的库需要python3.6+，因此需要先更新debian源：

vim /etc/apt/sources.list

在其中添加：

deb http://mirrors.163.com/debian/ testing main

执行：

apt-get update apt-get install python3.6 python3.6-dev python3.6-distutils apt-get install python-pip

安装wsgi：

sudo apt-get install libapache2-mod-wsgi-py3

在/etc/apache2/sites-available中新建flask.conf文件，在其中输入：

WSGIPythonPath /var/www/html/flask <VirtualHost *:80> # The ServerName directive sets the request scheme, hostname and port that # the server uses to identify itself. This is used when creating # redirection URLs. In the context of virtual hosts, the ServerName # specifies what hostname must appear in the request's Host: header to # match this virtual host. For the default virtual host (this file) this # value is not decisive as it is used as a last resort host regardless. # However, you must set it for any further virtual host explicitly. ServerName flask.yunwei123.tech # ServerAdmin webmaster@localhost DocumentRoot /var/www/html/flask # Available loglevels: trace8, ..., trace1, debug, info, notice, warn, # error, crit, alert, emerg. # It is also possible to configure the loglevel for particular # modules, e.g. #LogLevel info ssl:warn ErrorLog ${APACHE_LOG_DIR}/error.log CustomLog ${APACHE_LOG_DIR}/access.log combined WSGIScriptAlias / /var/www/html/flask/app.wsgi <Directory /var/www/html/flask> Require all granted <Files app.wsgi> Allow from all </Files> </Directory> # For most configuration files from conf-available/, which are # enabled or disabled at a global level, it is possible to # include a line for only one particular virtual host. For example the # following line enables the CGI configuration for this host only # after it has been globally disabled with "a2disconf". #Include conf-available/serve-cgi-bin.conf </VirtualHost> # vim: syntax=apache ts=4 sw=4 sts=4 sr noet

保存。

在网站根目录（这里是）新建app.wsgi文件，输入：

from server import app as application

再在同一个目录下新建server.py, 输入：

from flask import Flask import platform print(platform.python_version()) app = Flask(__name__) @app.route('/') def hello_world(): return platform.python_version() if __name__ == '__main__': app.run(host='0.0.0.0')

打开网页就可以看到啦。
