uwsgi模式_Uwsgi配置文档[通俗易懂]

Uwsgi配置文档

(2017-11-20 11:16:38)

uwsgi的安装也是可以直接采用yum安装，配置也是比较简单，

不过要想成功启动Python程序，需要用yum安装一个插件

uwsgi-plugin-python

如果想安装所有插件，可以直接安装uwsgi-plugin-all软件包

说明：

虚拟环境的python路径可以直接设置为本地python环境路径，其他路径根据自己需要修改

UWSGI 配置说明

1. 备份原配置文件 mv /etc/uwsgi.ini /etc/uwsgi.ini.bak

2. 修改uwsgi.conf.example文件

2.1 uwsgi 配置文件选择修改部分

processes = 4 #进程数量

threads = 5 #线程数量

2.2 uwsgi 配置文件必须修改部分

pythonpath = /opt/qogir/libs/bin/ #python 路径

virtualenv = /opt/qogir/libs/ #虚拟环境路径

socket = 192.168.2.22:9090 #uwsgi程序运行的Ip和端口

chdir = /var/www/cloudmonitor/qogir_api/ #指定代码运行目录(根据代码存放路径修改)

wsgi-file = /var/www/cloudmonitor/qogir_api/App.py #载入wsgi-file

master = true #允许主进程存在

callable = app #变量app 与 App.py文件中的app = Flask(__name__)对应

3. 移动配置文件到 /etc/ 下

cp uwsgi.ini.example /etc/uwsgi.ini

4. 运行 uwsgi 查看运行状态

启动uwsgi systemctl start uwsgi

查看uwsgi运行状态 systemctl status uwsgi

看到进程PID 以及 WSGI app ready 即为启动成功

Process: 5371 ExecStartPre=/bin/chown uwsgi:uwsgi /run/uwsgi (code=exited, status=0/SUCCESS)

Process: 5370 ExecStartPre=/bin/mkdir -p /run/uwsgi (code=exited, status=0/SUCCESS)

Main PID: 5372 (uwsgi)

Status: “uWSGI is ready”

CGroup: /system.slice/docker-8b7ab6359ca7a84144e2fef73b926c75b8bd3010162e533b93908215d499ea19.scope/system.slice/uwsgi.service

├─5372 /usr/sbin/uwsgi –ini /etc/uwsgi.ini

├─5373 /usr/sbin/uwsgi –ini /etc/uwsgi.ini

├─5378 /usr/sbin/uwsgi –ini /etc/uwsgi.ini

├─5383 /usr/sbin/uwsgi –ini /etc/uwsgi.ini

├─5384 /usr/sbin/uwsgi –ini /etc/uwsgi.ini

└─5385 /usr/sbin/uwsgi –ini /etc/uwsgi.ini

from flask.ext.restful import reqparse

WSGI app 0 (mountpoint=”) ready in 1 seconds on interpreter 0x128e120 pid: 5372 (default app)

*** uWSGI is running in multiple interpreter mode ***

spawned uWSGI master process (pid: 5372)

spawned uWSGI worker 1 (pid: 5378, cores: 5)

spawned uWSGI worker 2 (pid: 5383, cores: 5)

spawned uWSGI worker 3 (pid: 5384, cores: 5)

spawned uWSGI worker 4 (pid: 5385, cores: 5)

*** Stats server enabled on /run/uwsgi/stats.sock fd: 43 ***

Started uWSGI Emperor Service.

5.查看 uwsgi 运行日志

uwsgi 配置日志命令 daemonize = /var/log/uwsgi/uwsgi.log

daemonize 日志命令与 systemctl 启动模式有冲突，配置日志后启动会报错，所以只能查看systemctl日志

systemctl 日志查看命令 journalctl

附：uwsgi.conf.example

[uwsgi]

uid = uwsgi

gid = uwsgi

plugins = python

pythonpath = /opt/qogir/libs/bin/

virtualenv = /opt/qogir/libs/

chmod-socket = 660

socket = 192.168.2.22:9090

processes = 4

threads = 5

chdir = /var/www/cloudmonitor/qogir/qogir_api/

wsgi-file = /var/www/cloudmonitor/qogir/qogir_api/App.py

master = true

callable = app
