python - Nginx反向代理Flask发生Broken pipe错误
用flask写了个后台，直接用ip访问没有问题，但是用nginx反向代理多刷新几次页面就挂了。

访问路由：
@app.route('/')
@app.route('/index')
@flask_login.login_required
def index():
url = []
ip = []
total = {}
return flask.render_template('index.html', ip=ip, url=url, total=total)
--------------------- update -------------------
直接用命令行
python run.py启动没有问题启用supervisor重定向标准输出到日志文件，请求频繁就会爆Broken Pipe错误
不论是否使用supervisor，用nginx反向代理请求频繁都会报错
所以我个人觉得是写日志文件的原因，在supervisor和nginx里如何配置可以规避这个问题呢？
