CentOs7用nginx+uwsgi部署flask项目

前言

1. 最近在学习CentOs服务器环境，恰好作腾讯小程序设计大赛,项目须要用到flask和爬虫写后端。本文记录了如何部署flask项目
2. 如果在Ubuntu上用nginx+uwsgi部署flask项目,能够参考个人另一篇文章。
3. 版本:python3.5.0,CentOs7.6

一.环境准备

• python3.5.0
• setuptools
• pip3
• uwsgi
• flask

1. 安装python3.5.0

   1. 下载python的包[root@VM_0_15_centos local]# wget --no-check-certificate https://pypi.python.org/packages/source/s/setuptools/setuptools-19.6.tar.gz#md5=c607dd118eae682c44ed146367a17e26
   2. [root@VM_0_15_centos local]# tar -zxvf python3.5.0
   3. [root@VM_0_15_centos local]# cd Python3.5.0
   4. [root@VM_0_15_centos local]# ./configure
   5. [root@VM_0_15_centos local]# make &&make install
   6. 如今python3.5.0已经安装好了,可是极可能你输入python3 --version会发现找不到python
   7. 解决办法:看第二步

2. uwsgi(/nginx/python/pip3等)安装好后,command not found的解决办法

   • find / -name uwsgi
   • 假设找到的地址为 /usr/local/bin/uwsgi
   • 创建软链接 sudo ln -s /usr/local/bin/uwsgi /usr/bin/uwsgi
   • 注意:创建软连接时最好sudo,否则极可能仍是command not found

3. 安装setuptools

   1. 一样下载setuptools的包wget --no-check-certificate https://pypi.python.org/packages/source/s/setuptools/setuptools-19.6.tar.gz#md5=c607dd118eae682c44ed146367a17e26
   2. 解压 tar -zxvf setuptools-19.6.tar.gz
   3. cd setuptools-19.6
   4. 分别执行python3 setup.py build，python3 setup.py install

   5. 顺利的话:

      Processing dependencies for setuptools==19.6
      Finished processing dependencies for setuptools==19.6

4. 安装pip

   1. 一样下载pip的包wget --no-check-certificate https://pypi.python.org/packages/source/p/pip/pip-8.0.2.tar.gz#md5=3a73c4188f8dbad6a1e6f6d44d117eeb
   2. 解压 tar -zxvf pip-8.0.2.tar.gz
   3. cd pip-8.0.2
   4. 分别执行python3 setup.py build，python3 setup.py install

   5. 顺利的话:

      Processing dependencies for pip==8.0.2
      Finished processing dependencies for pip==8.0.2

5. 安装pip须要的openssl和openssl-devel
   执行yum install openssl和yum install openssl-devel

   注意极可能还需 yum -y install python3-devel

6. 安装uwsgi pip3 install uwsgi

7. 安装flask和项目须要的一些包(只是本项目须要的包)
   首先进入到项目目录里

   • pip3 install flask
   • pip3 install virtualenv
   • pip3 install flask_sqlalchemy
   • pip3 install sqlalchemy
   • pip3 install flasgger
   • pip3 install flask_cors

二.代理服务器配置

1. 配置文件uwsgi.ini
   sudo vim uwsgi.ini
   基本内容:

   [uwsgi]
   chdir=/home/dbc/gameEvent
   callable=app
   wsgi-file=app.py
   processes = 5
   http=0.0.0.0:8001
   chmod-socket=666
   max-requests=1000

2. nginx配置
   进入nginx的conf目录下(目录结构不同哟!)
   cd /www/server/nginx/conf
sudo vim flask.conf

   server{
     listen 8001;
     server_name 0.0.0.0; #访问ip
   
     location / {
       include uwsgi_params;
       uwsgi_pass 127.0.0.1:5000;  #代理到uwsgi.ini里兼容的ip和端口
     }
    }

3. 生成uwsgi日志目录
   mkdir /var/log/uwsgi
4. 跑起来
   uwsgi uwsgi.ini -d /var/log/uwsgi.log
