使用uWSGI+Nginx部署Flask应用,不成功

uwsgi启动后
WSGI app 0 (mountpoint='') ready in 0 seconds on interpreter 0x7fe603c0b1f0 pid: 1228 (default app)
*** uWSGI is running in multiple interpreter mode ***
spawned uWSGI master process (pid: 1228)
spawned uWSGI worker 1 (pid: 1229, cores: 1)
spawned uWSGI worker 2 (pid: 1230, cores: 1)
spawned uWSGI worker 3 (pid: 1231, cores: 1)
spawned uWSGI worker 4 (pid: 1232, cores: 1)

页面显示
502 Bad Gateway

uwsgi输出
invalid request block size: 4665 (max 4096)...skip

我刚好也是这样部署Flask，刚好也是出现这样的错误，LZ解决了的话告诉我。今晚我再折腾一下看。

如果使用了 flask.ext 的话，uwsgi 是部署不成功的。你可以尝试一下简单的 hello world。

但是问题是，你为何要用 uwsgi？更好的选择是什么？

直接使用 gunicorn 就挺好的，uWSGI 安装配置太麻烦了，而且它的异步模式在 Flask 上可能出现问题。

/tmp/uwsgi.sock 权限问题？
sudo chmod 755 /tmp/uwsgi.sock

@yetone 试过，好像没有用
@lepture 确实是最简单的hello world

@jmania 你是不是直接用了 uWSGI 提供的 http 服务？

jmania

2012-11-28 23:40:56 +08:00

@yetone 这个是我uWSGI的配置
<uwsgi>
<socket>/tmp/uwsgi.sock</socket>
<virtualenv>/Users/jmania/Python/virtualenv/testenv</virtualenv>
<pythonpath>/Users/jmania/Python/myflask/test</pythonpath>
<chdir>/Users/jmania/Python/myflask/test</chdir>
<module>store</module>
<callable>app</callable>
<master/>
<processes>4</processes>
<memory-report/>
<chmod-socket>666</chmod-socket>
</uwsgi>

nginx 的配置是怎樣呢？

2012-11-29 00:16:56 +08:00

贴上 Nginx 配置吧

@raptium
@yetone
nginx 的配置,
我的系统是Mac
server {
listen 80;
server_name www.myapp.com;

location / {
include uwsgi_params;
uwsgi_pass unix:/tmp/uwsgi.sock;
}
}

mark , 俺之前部署也是一片悲伤。

无奈换了apache2 mod_wsgi

试下这个呢： unix:///tmp/uwsgi.sock;

@xuwenbao 还是不行

创建目录（site_doc是main.py的存放目录，/home/python_venv是你的python虚拟环境）
mkdir -p /home/python_venv && \
mkdir -p /home/site_doc && \
chown -R www:www /site_doc && \
chmod -R 775 /site_doc

# 安裝 virtualenv ###########################
easy_install virtualenv && \
virtualenv --no-site-packages /home/python_venv

# 安裝 xx 到虚拟环境 ###########################
# 我安装了flask，你的bottle就换成bottle
source /home/python_venv/bin/activate && \
easy_install Flask && \
deactivate

# nginx配置
location / {
uwsgi_pass 127.0.0.1:8888;
include uwsgi_params;
uwsgi_param UWSGI_PYHOME /home/python_venv;
uwsgi_param UWSGI_CHDIR /home/site_doc;
uwsgi_param UWSGI_SCRIPT main;
}

# uwsgi启动
/usr/local/uwsgi/uwsgi -s :8888 -M -p 4 -t 30 -R 10000 --post-buffering 40960 -d /usr/local/uwsgi/logs/uwsgi.log --disable-logging --close-on-exec --env PYTHON_EGG_CACHE=/tmp --socket-timeout 60 --http-timeout 60 --limit-as 512 --gid www --uid www --no-site --vhost

注意路径问题，自己修改一下
