配置文件

[uwsgi]
http = 127.0.0.1:1088
chdir = /Users/libaotong/Documents/python/tfgame_spider/
wsgi-file = run.py
callable = app
processes = 4
master = true
logto = logs/online_api.log
threads = 2
daemonize = logs/uwsgi.log
virtualenv=/Users/libaotong/Documents/python/tfgame_spider/venv
stats = 127.0.0.1:9191

如果配合nginx使用，则配置为：socket = 127.0.0.1:1088

mac运行错误

运行时报错

objc[61000]: +[__NSPlaceholderDate initialize] may have been in progress in another thread when fork() was called. We cannot safely call it or ignore it in the fork() child process. Crashing instead. Set a breakpoint on objc_initializeAfterForkError to debug.

原因：macOS的High Sierra以上的操作系统对多进程的限制

解决办法

运行前，导入系统变量

export OBJC_DISABLE_INITIALIZE_FORK_SAFETY=YES

一劳永逸的办法：

sudo echo "export OBJC_DISABLE_INITIALIZE_FORK_SAFETY=YES" >> ~/.bash_profile && source ~/.bash_profile

BTW

# 杀掉所有uwsgi
ps -ef|grep uwsgi|grep -v '.svn'|awk '{print $2}'|xargs kill -9

# 启动uwsgi
uwsgi --ini config/uwsgi.ini
