gunicorn配置是由一个不再由我们支配的人完成的,而且我真的不知道枪炮,我无法修复甚至找不到问题,所以我恢复到版本18.0并且它现在正在工作.但是,我想最终升级它并将配置放在可以工作的形状中.我有一种感觉,当前的配置是次优或多余的,但我无法确定:-).
在环境中没有任何改变(或者是gunicorn运行的virtualenv),只有gunicorn本身升级了. Systemctl在systemctl start gunicorn上产生了这个错误:
● gunicorn.service - gunicorn daemon (production) Loaded: loaded (/usr/lib/systemd/system/gunicorn.service; enabled) Active: Failed (Result: resources) since Tue 2015-02-17 20:55:41 UTC; 8s ago Process: 2837 ExecStop=/bin/kill -s QUIT $MAINPID (code=exited,status=0/SUCCESS) Process: 9608 ExecReload=/bin/kill -s HUP $MAINPID (code=exited,status=0/SUCCESS) Process: 5353 ExecStart=/home/django/gunicorn/run.sh (code=exited,status=0/SUCCESS) Main PID: 24876 (code=exited,status=0/SUCCESS) Feb 17 20:55:41 ashima systemd[1]: PID file /home/django/gunicorn/gunicorn.pid not readable (yet?) after start.

尝试从shell手动运行run.sh(下面粘贴)中包含的gunicorn命令,它只是立即退出而不会产生任何错误,退出代码为0.没有记录任何内容.事实上,在日志文件变得惊人的大小之后,看起来我的前任禁用了gunicorn记录了一段时间,但这是另一天的问题.

解决方法
原来这是配置文件中有问题的行:
worker_class =’egg:gunicorn#sync’
它导致了这个错误:
Error: class uri 'egg:gunicorn#sync' invalid or not found: [Traceback (most recent call last): File "/home/django/.venv/lib/python2.7/site-packages/gunicorn/util.py",line 113,in load_class return pkg_resources.load_entry_point(dist,section,name) File "/home/django/.venv/lib/python2.7/site-packages/setuptools-0.6c11-py2.7.egg/pkg_resources.py",line 318,in load_entry_point return get_distribution(dist).load_entry_point(group,line 2220,in load_entry_point raise ImportError("Entry point %r not found" % ((group,name),)) ImportError: Entry point ('gunicorn.workers','sync') not found ]
用worker_class =’sync’替换它修复了ImportError,从而修复了问题.在18.0中没有必要更改其他配置 – > 19.2.1升级.
gunicorn的文档似乎有问题,我打算报告,因为在撰写本文时,the docs for v19.2.1仍然声明egg:gunicorn#[worker]语法是有效的. (这里的例子使用了gevent,但它看起来应该适用于其他类型).谁知道,它可能在某些情况下是有效的,但在我的(带有pip的virtualenv中的gunicorn),它不是.
