Body:

1. Installing Nginx

1.1 Configuring Yum third-party feeds

The CentOS default source does not have an Nginx installation package, so let's modify the third-party source.

#cd ~ #wget http://www.atomicorp.com/installers/atomic#sh./atomic#yum check-update

1.2 Installing Nginx

#yum Install Nginx#service nginx start
#chkconfig Nginx on

2. Installation Class Library

#cd ~
#yum Groupinstall "Development tools" #yum install Zlib-devel bzip2-devel pcre-devel openssl-devel ncurses-devel Sqlite-devel Readline-devel Tk-devel

3. Install Python

3.1 Installing the latest version

CentOS 6.6 is installed by default python2.6.6 version, we now install the latest version of python2.7.9

#cd ~ #wget Https://www.python.org/ftp/python/2.7.9/Python-2.7.9.tgz#tar xvf python-2.7.9.tgz#cd python-2.7.9.tgz#./ Configure--prefix=/usr/local#make && make Altinstall

3.2 Back up old version, link new version

Since the CentOS system's Yum program uses the python2.6.6 version of the previous system, in order to resolve version conflicts, we will first distinguish and relink the old and new versions of Python.

#mv/usr/bin/python/usr/bin/python2.6.6#ln-s/usr/local/bin/python2.7/usr/bin/python

3.3 Modifying the Yum configuration file

To reassign the Python program path that it uses:

#vi/usr/bin/yum

Find to:

#!/usr/bin/python

Modified to:

#!/usr/bin/python2.6.6

After the modifications are complete, use the "python" command to enter the python2.7.9 environment.

Exit the environment using the exit () command.

4. Install Python package management tool

9. Environment configuration

9.1 Configuration Declarations

First I want to declare the absolute location of several fixed directories. (This section is configured in strict accordance with the following location & if you need to modify the path, modify the relevant configuration file)

Nginx configuration file:/etc/nginx/vhosts/www.a.com.conf

#mkdir/etc/nginx/vhosts                                //New Nginx Configuration folder

Project root directory:/usr/share/nginx/www/www.a.com

Log file directory:/usr/share/nginx/log

#mkdir/usr/share/nginx/log                             //new log folder

Uwsgi configuration file:/etc/uwsgi/www.a.com.ini

#mkdir/etc/uwsgi                                       //New UWSGI Configuration folder

9.2 Configuring UWSGI

9.2.1 New UWSGI configuration file

#vi/etc/uwsgi/uwsgi_www.a.com.ini//New UWSGI configuration file

Enter the blue content below into the Wusgi_www.a.com.ini file

[Uwsgi]
Master = True
Vhost = True
workers = 2
Reload-mercy = Ten
Vacuum = True
max-requests = +
Limit-as =
chmod-socket = 666
socket =/tmp/uwsgi_www.a.com.sock
venv =/usr/share/nginx/www/www.a.com/env
chdir =/usr/share/nginx/www/www.a.com
module = MyApp
callable = App
touch-reload =/usr/share/nginx/www/www.a.com
pidfile =/var/run/uwsgi_www.a.com.pid
daemonize =/usr/share/nginx/log/uwsgi_www.a.com.log

9.2.2 Adding a boot script to Uwsgi

#vi/etc/init.d/uwsgi_www.a.com
Enter the blue content below into the uwsgi_www.a.com file
#! /bin/sh# chkconfig:2345 25# description:startup script for Uwsgi webserver on Debian. Place in/etc/init.d and# Run ' update-rc.d-f uwsgi defaults ', or with the appropriate command on your# distro. For Centos/redhat run: ' Chkconfig--add Uwsgi ' # # # BEGIN INIT info# provides:uwsgi# required-start: $all # Requ  Ired-stop: $all # default-start:2 3 4 * default-stop:0 1 6# short-description:starts the UWSGI web server# Description:starts Uwsgi using start-stop-daemon### END INIT infopath=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/u sr/sbin:/usr/bindesc= "Uwsgi Daemon" name=uwsgi_www.a.comdaemon=/usr/local/bin/uwsgiconfigfile=/etc/uwsgi/$ name.inipidfile=/var/run/$NAME. pidscriptname=/etc/init.d/$NAMEset-e[-X "$DAEMON"] | | Exit 0do_start () {$DAEMON $CONFIGFILE | | echo-n "UWSGI already Running"}do_stop () {$DAEMON--stop $PIDFILE | | echo-n "UW SGI not running "rm-f $PIDFILEecho" $DAEMON stoped.

#chkconfig--add uwsgi_www.a.com//Add service
#chkconfig uwsgi_www.a.com on//Set boot up

9.2.3 modifying Nginx configuration files

First open the Nginx configuration file:

#vi/etc/nginx/nginx.conf

Find to:

include/etc/nginx/conf.d/*.conf;

Modified to:

#include/etc/nginx/conf.d/*.conf;                         Add a # sign at the beginning of the line comment out this sentence
include/etc/nginx/vhosts/*.conf;                          Referencing the app configuration file

9.2.4 New project configuration file

#vi/etc/nginx/vhosts/www.a.com.conf

Enter the blue content below into the uwsgi_www.a.com file

server {Listen 80; server_name www.a.com;
Index  index.htm index.html;　　　　　　　　　　Location/{include uwsgi_params; Uwsgi_pass Unix:///tmp/uwsgi_www.a.com.sock;
}}

10. Testing

10.1 Open Service

#service nginx start#service uwsgi_www.a.com start

10.2 New Portal Component files

#vi/usr/share/nginx/www/www.a.com/myapp.py//The following blue contents into the uwsgi_www.a.com file from flask import Flaskapp = Flask (__name__) @app. Route ('/') def hello_world (): Return ' Hello world!  ' if __name__ = = ' __main__ ': App.run ()

"Hello world!" appears when running browser access www.a.com Indicates that the environment has been successfully built.
