Flask+uwsgi+Nginx环境搭建

2019独角兽企业重金招聘Python工程师标准>>>

开源软件准备
需要的软件列表：
setuptools-33.1.1.zip
Python-2.7.13.tgz
pip-9.0.1.tar.gz
nginx-1.10.3.tar.gz
软件统一上传到/usr/local/src/下，python是使用自己编译的。
Python安装
先安装以下的软件（如果有的话，就可以不安装了，例如使用rpm -qa zlib-devel先查看下）
yum install zlib-devel -y
yum install openssl-devel -y

tar -zxvf解压
./configure --prefix=/usr/local/python #安装到/usr/local/python目录下。
make
make install
setuptool和pip安装
unzip解压setuptool
/usr/local/python/bin/python setup.py install

tar -zxvf解压pip
/usr/local/python/bin/python setup.py install
flask和uwsgi安装
使用pip安装flask和uwsgi
/usr/local/python/bin/pip install flask
/usr/local/python/bin/pip install uwsgi
nginx安装
先安装pcre-devel：
yum install pcre-devel -y

./configure --prefix=/usr/local/nginx
make && make install

nginx使用uwsgi配置

cat /usr/local/nginx/conf/nginx.conf

#user  nobody;
worker_processes  1;events {worker_connections  1024;
}http {include       mime.types;default_type  application/octet-stream;log_format  main  '$remote_addr - $remote_user [$time_local] "$request" ''$status $body_bytes_sent "$http_referer" ''"$http_user_agent" "$http_x_forwarded_for"';sendfile        on;keepalive_timeout  65;server {listen       8080;access_log  /usr/local/nginx/logs/flask_access.log main;error_log /usr/local/nginx/logs/flask_error.log error;client_max_body_size 200M;location / {include      uwsgi_params;uwsgi_pass   unix:/dev/shm/uwsgi.sock;index  index.html index.htm;}}}

启动nginx：
/usr/local/nginx/sbin/nginx -t
/usr/local/nginx/sbin/nginx

注意：uwsgi_pass unix:/dev/shm/uwsgi.sock;需要和uwsgi的配置相对应！

uwsgi配置
cat /root/uwsgi.ini

[uwsgi]
uid = root
gid = root
socket = /dev/shm/uwsgi.sock
chmod-socket = 666
enable-threads = true
master = true
plugins = /usr/local/python/bin/python
vhost = true
workers = 5
max-requests = 1000
pidfile = /var/run/uwsgi.pid
daemonize = /var/log/uwsgi.log
chdir = /root/ops_dev/
module = ops_dev
callable = app

启动uwsgi，有些报错没什么事：
/usr/local/python/bin/uwsgi /root/uwsgi.ini

编写测试样例进行测试
cat /root/ops_dev/ops_dev.py
```
# -*- coding: UTF-8 -*-
from flask import Flask
app = Flask(__name__)@app.route('/', methods=['GET', 'POST'])
def index():return 'Hello  world,Python ops_dev!'
```
编写完需要重启uwsgi，开改动代码都需要重启uwsgi，直接使用pkill进行重启即可:
pkill uwsgi

访问http://localhost:8080/进行测试。

访问日志记录(nginx和uwsgi的访问日志，可用来排错。)：
