apache+flask部署

wsgi方式

1.安装apache

1.解压httpd并进行安装

    # tar zxvf httpd-2.2.15.tar.gz

    # cd httpd-2.2.15
    # ./configure --prefix=/opt/oracle/apache --enable-rewrite --enable-so(大约两分钟,选项的作用主要是允许动态加载模块,以后我们要加载mod_wsgi)
    # make
    # make install

2.启动apache服务
    # /opt/oracle/apache/bin/apachectl start

3.测试
    # curl 127.0.0.1
当看到"It works"代表apache配置成功

2.安装mod_wsgi
1.解压,安装

    #mkdir /var/run/mod_wsgi
    # tar zxvf mod_wsgi-3.3.tar.gz 
    # cd mod_wsgi-3.3/
    # ./configure --with-apxs=/opt/oracle/apache/bin/apxs(apache动态添加的一个模块)
                       --with-python=/usr/bin/python(指定python的路径)
                       --with-mutex-dir=/var/run/mod_wsgi(最大缓冲值的目录)
    # make 在这一步如果出现make: *** [mod_wsgi.la]错误则需要重新编译安装python2.7并加上--enable-shared参数.
    # make install

2.配置Apache

httpd.conf去除如下行的注释

#Include conf/extra/httpd-vhosts.conf

httpd.conf修改DocumentRoot到程序所在目录

DocumentRoot "/opt/oracle/apache/htdocs/ROOT/panoramic"

3.修改Virtual Host配置

NameVirtualHost *

LoadModule wsgi_module modules/mod_wsgi.so

<VirtualHost *>
ServerName localhost
 
WSGIDaemonProcess flask_web threads=30
WSGIProcessGroup flask_web
WSGIScriptAlias /monitor/panoramic /opt/oracle/apache/htdocs/ROOT/panoramic/monitor.wsgi
 
<Directory /opt/oracle/apache/htdocs/ROOT/panoramic>
WSGIProcessGroup flask_web
WSGIApplicationGroup %{GLOBAL}
Order deny,allow
Allow from all
</Directory>
</VirtualHost>

4.创建测试页面

创建flask_web.py脚本

monitor.wsgi内容如下

import sys

sys.path.insert(0, '/opt/oracle/apache/htdocs/ROOT/panoramic')
from monitor import app as application

重启apache访问IP/app

cgi方式

首先，你需要创建 CGI 应用文件。我们把它命名为 yourapplication.cgi:

#!/usr/bin/python

from wsgiref.handlers import CGIHandler

from flask_web import app

CGIHandler().run(app)

配置httpd.conf

ScriptAlias /monitor/panoramic  "/opt/oracle/apache/htdocs/ROOT/panoramic/flask_web.cgi"

httpd.conf修改DocumentRoot到程序所在目录

DocumentRoot "/opt/oracle/apache/htdocs/ROOT/panoramic"
