Apache+mod_wsgi+Flask部署文檔--ubuntu

本文檔適用於:

1. python3.5

2. apache2.4

3. mod_wsgi4.3

部署過程:

1. 安裝Apache

   $ sudo apt-get install apache2
   

   啓動apache服務

   $ sudo /etc/init.d/apache2 start
   

2. 安裝mod_wsgi

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

   如果項目開發使用的是python2,則不需要加-py3

   啓動mod_wsgi

   $ sudo a2enmod wsgi
   

3. 創建.wsgi文件,該文件用於啓動項目,如下

   import os
   import sys
   import re
   
   //進入虛擬環境,相當於souce .venv/bin/active
   activate_this = '/home/sam/Snipe/.venv/bin/activate_this.py'
   with open(activate_this) as file_:
       exec(file_.read(), dict(__file__=activate_this))
   
   //這裏需要導入環境變量
   
   from app import app as application
   

4. 創建apache配置文件,配置虛擬主機,將配置文件添加到/etc/apache2/sites-available/,如下

   <VirtualHost 172.18.215.158:5000>
       ServerAdmin [email protected]
       ServerName sysu.snipe
       DocumentRoot /home/sam/Snipe/src/web/
       #將/請求轉發給/home/sam/Snipe/src/web/Snipe.wsgi
       WSGIScriptAlias / /home/sam/Snipe/src/web/Snipe.wsgi
       #配置本項目的守護進程
       WSGIDaemonProcess Snipe user=sam group=sam threads=10 home=/home/sam/Snipe/src/web/ 
       <Directory /home/sam/Snipe/src/web/>
           WSGIProcessGroup Snipe
           Require all granted
       </Directory>
       ErrorLog /var/log/apache2/error_snipe.log
   </VirtualHost>
   

   使用apachectl configtest命令可以查看配置文件是否正確

5. 配置監聽端口,添加Listen 172.18.215.158:5000到配置文件/etc/apache2/ports.conf,使apache監聽172.18.215.158:5000

6. 激活虛擬主機

   $ sudo a2ensite /etc/apache2/sites-available/Snipe.conf
   

7. 重新加載apache

   $ sudo /etc/init.d/apache2 reload
   

   打開瀏覽器,輸入172.18.215.158:5000,即可看到項目web端~~~!!!

項目結構

+/home/sam/Snipe/
    +.venv
