nginx+uwsgi部署python应用

uwsgi 配置

其实nginx+python+django的配置主要是uwsgi的配置。这里直接贴出我的uwsgi.ini的配置。各个参数具体参看uwsgi文档。

[uwsgi]
#socket = 127.0.0.1:8000 
socket = /tmp/uwsgi.sock
master = true
chdir = /home/lovedboy/myproject/ # django工程目录
wsgi-file = /home/lovedboy/myproject/myapp/wsgi.py
processes = 2
listen = 15000
enable-threads = true
daemonize = /home/lovedboy/uwsgi/uwsgi.log
pidfile = /home/lovedboy/uwsgi/uwsgi.pid
pythonpath = /home/lovedboy/myproject/
buffer-size =  32768
reload-mercy = 8
vacuum = true
max-requests = 20000
socket-timeout = 20
harakiri = 20
memory-report = true

配置完成后，直接用如下命令启动:

sudo uwsgi --ini uwsgi.ini

如果启动成功， tail 一下uwsgi.log 会有类似如下的日志：

停掉uwsgi 服务:

sudo uwsgi --stop  uwsgi.pid

平滑重启:

sudo uwsgi --reload uwsgi.pid

nginx 配置

location / { 
	include        uwsgi_params;
	#uwsgi_pass     127.0.0.1:8888;
	uwsgi_pass     unix:///tmp/uwsgi.sock;
	uwsgi_read_timeout 1000;
}   

nginx 配置更改后，重启nginx。

sudo nginx -s reload
