使用uwsgi部署Flask项目

1.配置虚拟环境
1.1 pip3 install virtualenv
1.2 创建虚拟环境：virtualenv venv
1.3 激活虚拟环境：source venv/bin/activate
1.4 在虚拟环境中安装flask,uwsgi库：pip3 install flask; pip3 install uwsgi
（可能遇到的坑：缺少依赖：yum install -y python3-devel）
1.5 创建配置文件：touch uwsgi.ini
1.6 内容为：[uwsgi]
http = 192.168.126.128:5000
chdir = /home/flask_web
virtualenv =/home/flask_web/venv
wsgi-file = /home/flask_web/app.py
callable = app
#plugins = python
master = true
vacuum = true
chmod-socket = 664
processes = 5
daemonize = /home/flask_web//uwsgi.log
pidfile = /home/flask_web/uwsgi.pid

注：当利用nginx部署：
[uwsgi]
socket = 127.0.0.1:5000
chdir = /home/flask
virtualenv =/home/flask/venv
wsgi-file = /home/flask/app.py
callable = app
#plugins = python
master = true
vacuum = true
chmod-socket = 664
processes = 5
daemonize = /home/flask/uwsgi.log
pidfile = /home/flask/uwsgi.pid

nginx中配置:
server {
        listen       80;
        server_name  192.168.1.134;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
            include /home/application/nginx/conf/uwsgi_params;
            uwsgi_pass 0.0.0.0:5000;
        }

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }


1.7 进入pycharm中Terminal将依赖库版本导出: pip3  freeze >  requirements.txt

1.8 在虚拟环境中安装依赖库：pip3 install -r requirements.txt

1.9 启动 uwsgi.ini:uwsgi uwsgi.ini
(可能遇到的坑：ps -ef|grep uwsgi发现没有进程，删掉/home/flask_web/uwsgi/pid 再重新执行一遍 uwsgi uwsgi.ini)
2.0 将项目copy到/home/flask_web目录下，并将.py文件赋权
2.1 启动uwsgi.ini
2.2 ps -ef|grep uwsgi  查看进程是否启动
2.3 重启uwsgi:  uwsgi --reload uwsgi.pid
2.4 停止： uwsgi --stop uwsgi.pid
2.5 启动： uwsgi --ini uwsgi.ini
