pybottle gunicorn gevent 不共享全局字典

Question

from gevent import monkey
monkey.patch_all()

import bottle

app = bottle.Bottle()
COUNT = 0

@app.route('/inc', method='GET')
def count():
    global COUNT
    COUNT += 1
    return COUNT

def main():
    app.run(
        server="gunicorn",
        host="0.0.0.0",
        port=port,
        workers=50,
        worker_class="gevent",
        debug=False,
        reloader=False,
    )

if __name__ == '__main__':
    main(sys.argv[1:])

当我刷新 0.0.0.0/inc 时，它不是线性增加，而是从 1 到 0 到 1 到 0 到 2 到 1 到 0，等等

这告诉我每个线程（gevent worker）维护 COUNT 值

如何在所有 gevent worker 之间共享全局变量？

-- 我确认确实单独的 greenlet 正在跟踪它自己的 COUNT

Answer 1

    app.run(
        server='gevent',
        host="0.0.0.0",
        port=port
    )

删除 gunicorn 对我有用

pybottle gunicorn gevent 不共享全局字典

pybottle gunicorn gevent not sharing global dict

gevent
