centos 配置 nginx 和 uwsgi 运行 python 脚本

  • by

安装 uwsgit

pip install uwsgi

添加响应文件。

vim /data/install/bin/pptserver.py

内容是：

cat /data/install/bin/pptserver.py 
from flask import Flask,render_template

app = Flask(__name__)

@app.route('/pptserver')
def index():
 return "Test message, you get it"

if __name__ == '__main__':
 app.run()

然后配置文件修改：

cat /data/install/conf/uwsgi.conf

[root@iZ23srfk8ttZ bin]# cat /data/install/conf/uwsgi.conf 
[uwsgi]
## For directlly http access
http-socket=127.0.0.1:8888

### For nginx proxy
#socket=127.0.0.1:8888
wsgi-file=/data/install/bin/pptserver.py
#plugins = python
callable = app
#chdir = /data/install/bin
touch-reload=/data/install/conf/
processes = 2
threads = 2
stats = 127.0.0.1:9191
post-buffering = 8192
buffer-size = 65535
socket-timeout = 10
uid = apache
gid = apache
master = true
#protocol = uwsgi

运行 uwsgi:
注意：当直接curl测试uwsgi的时候，配置为 http-socket=xxx
当使用nginx进行代理时，要配置为 socket=xxx

nohup uwsgi --ini /data/install/conf/uwsgi.conf &

检查服务：

#netstat -atnp | grep uwsgi
tcp        0      0 127.0.0.1:9191              0.0.0.0:*                   LISTEN      584/uwsgi           
tcp        0      0 127.0.0.1:8888              0.0.0.0:*                   LISTEN      584/uwsgi

可以看到 9191端口是健康检查服务， 8888 端口是服务端口

测试下业务口：

#curl http://localhost:8888/pptserver
Test message, you get it

测试监控

#curl "http://localhost:9191"

}

配置 nginx 转发

配置 nginx 文件内容为：

location ~ /pptserver {
        include      uwsgi_params;
        uwsgi_pass   127.0.0.1:8888; # 指向uwsgi 所应用的内部地址,所有请求将转发给uwsgi 处理
    }

修改 uwsgi的配置为：

[root@iZ23srfk8ttZ bin]# cat /data/install/conf/uwsgi.conf 
[uwsgi]
## For directlly http access
#http-socket=127.0.0.1:8888

### For nginx proxy
socket=127.0.0.1:8888
wsgi-file=/data/install/bin/pptserver.py
#plugins = python
callable = app
#chdir = /data/install/bin
touch-reload=/data/install/conf/
processes = 2
threads = 2
stats = 127.0.0.1:9191
post-buffering = 8192
buffer-size = 65535
socket-timeout = 10
uid = apache
gid = apache
master = true
#protocol = uwsgi

然后测试nginx的接口：

curl "http://ginkgoo.org/pptserver"
Test message, you get it
