flask 优化

优化

并发4个线程：
uwsgi -s :9090 -w myapp -p 4 
主控制线程+4个线程：
uwsgi -s :9090 -w myapp -M -p 4 
执行超过30秒的client直接放弃：
uwsgi -s :9090 -w myapp -M -p 4 -t 30 
限制内存空间128M：
uwsgi -s :9090 -w myapp -M -p 4 -t 30 --limit-as 128 
服务超过10000个req自动respawn：
uwsgi -s :9090 -w myapp -M -p 4 -t 30 --limit-as 128 -R 10000 
后台运行等：
uwsgi -s :9090 -w myapp -M -p 4 -t 30 --limit-as 128 -R 10000 -d uwsgi.log 

命令行参数 uwsgi将gevent做为模块uwsgi -s 127.0.0.1:8080 --processes 4 --loop gevent --enable-threads --async 128 --disable-logging --wsgi-file test.pyuwsgi将gevent内置uwsgi --http :8080 --file test.py --gevent 2000 -l 1000 -p 1 -L 参数解释
uwsgi将gevent做为模块
uwsgi -s 127.0.0.1:8080 --processes 4 --loop gevent --enable-threads --async 128 --disable-logging --wsgi-file test.py
如题谁有 uwsgi 的配置文件让我参考一下，我的配置老是出现 upstream prematurely closed connection while reading response header from upstream, client 这样的错误。 以下是我自己的配置： [uwsgi] #coding:utf-8
uwsgi 启动时所使用的地址与端口
socket = 127.0.0.1:8001
master = true
指向网站目录
chdir = /obj1/wechat/
profiler = true
enable-threads = true
logdate = true
memory-report=true
limit-as = 6048
daemnize = /obj1/wechat.log
python 启动程序文件
wsgi-file = manage.py
python 程序内用以启动的 application 变量名
callable = app
处理器数
processes = 4
线程数
threads = 2
#状态检测地址 stats = 127.0.0.1:9191
uwsgi_read_timeout = 600
harakiri = 1200
gevent = 100
./uwsgi -w tests.cpubound_green -s :3031 --async 30 --ugreen
./uwsgi -s :3031 -w simple_app --daemonize /tmp/mylog.log
./uwsgi -s :3031 -w simple_app --logto /tmp/mylog.log
# logto2 only opens the log file after privileges have been dropped to the specified uid/gid.
./uwsgi -s :3031 -w simple_app --uid 1001 --gid 1002 --logto2 /tmp/mylog.log
uwsgi --gevent 100 --gevent-monkey-patch --http :9090 -M  --processes 4 --wsgi-file wsgi.py
