Django，nginx和uWSGI緩存結果直到uWSGI/MySQL重新啓動

我已經在Django中編寫了一個服務器應用程序，並向Tastypie的移動應用程序提供API，並使用本地MySQL服務器爲該數據庫提供服務。Django，nginx和uWSGI緩存結果直到uWSGI/MySQL重新啓動

似乎查詢被緩存直到進程被終止或終止。如果我在後端創建一個新用戶，它將首先出現在列表中，如果我重新啓動uWSGI或MySQL，或者如果我從另一個瀏覽器登錄到後端。

MySQL進程列表

41 example localhost:58747 example  13 Sleep                              
42 example localhost:58748 example  16 Sleep

另外，如果我殺了這些Sleep'ed它也將觸發數據的刷新過程。

uWSGI配置

[uwsgi] 
vhost = true 
plugins = python 
socket = /tmp/example.com.sock 
master = true 
enable-threads = true 
processes = 2 
wsgi-file = /var/sites/example-server/example/example/wsgi.py 
virtualenv = /var/sites/example-server/PYTHON_ENV 
chdir = /var/sites/example-server/example 
touch-reload = /var/sites/example-server/example/reload

nginx的配置

server { 
    client_max_body_size 20M; 
    listen 80; 
    server_name example.com; 
    access_log /var/log/nginx/example.com_access.log; 
    error_log /var/log/nginx/example.com_error.log; 

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

    location /media/ { 
     alias /var/sites/example-server/example/example/media/; 
    } 

    location /static/ { 
     alias /var/sites/example-server/example/example/static/; 
    } 
}

的my.cnf

[client] 
port   = 3306 
socket   = /var/run/mysqld/mysqld.sock 

[mysqld_safe] 
socket   = /var/run/mysqld/mysqld.sock 
nice   = 0 

[mysqld] 
user   = mysql 
pid-file  = /var/run/mysqld/mysqld.pid 
socket   = /var/run/mysqld/mysqld.sock 
port   = 3306 
basedir   = /usr 
datadir   = /var/lib/mysql 
tmpdir   = /tmp 
lc-messages-dir = /usr/share/mysql 
skip-external-locking 
bind-address   = 127.0.0.1 
key_buffer    = 16M 
max_allowed_packet  = 16M 
thread_stack   = 192K 
thread_cache_size  = 8 
myisam-recover   = BACKUP 
query_cache_limit  = 1M 
query_cache_size  = 16M 
log_error = /var/log/mysql/error.log 
expire_logs_days  = 10 
max_binlog_size   = 100M 
mysqldump] 
quick 
quote-names 
max_allowed_packet  = 16M 

[mysql] 

[isamchk] 
key_buffer    = 16M 

transaction-isolation = READ-COMMITTED 
!includedir /etc/mysql/conf.d/

我能做些什麼，使這個問題消失？

我有同樣的行爲，發現這個職位https://plus.google.com/u/0/101898908470597791359/posts/AuMJdgEo93k

添加Django上的settings.py這條線（只有OPTIONS鍵）：

DATABASES = { 
    'default': {  
     'OPTIONS': { "init_command": "SET storage_engine=INNODB, SESSION TRANSACTION ISOLATION LEVEL READ COMMITTED", } 
    } 
}

似乎已經解決了這個問題。
