我正在尝试设置我的Django应用程序以使用python3.5(python2.7是默认设置)
所以我在3.5中创建了一个虚拟环境,并部署了我的Django项目。在
我现在想和uwsgi合作
/etc/uwsgi公司/皇帝.ini在
[uwsgi]
emperor = etc/uwsgi/sites
logto = /var/log/uwsgi
/etc/uwsgi/站点/ams.ini公司在
^{pr2}$/etc/systemd/系统/uwsgi.服务在
[Unit]
Description=uWSGI Emperor service
After=syslog.target
[Service]
ExecStart=/usr/local/bin/uwsgi --http :8000 --emperor /etc/uwsgi/sites
Restart=always
KillSignal=SIGQUIT
Type=notify
StandardError=syslog
NotifyAccess=all
[Install]
WantedBy=multi-user.target
如果我从虚拟环境中启动uwsgi,我可以成功地启动它
uwsgi --http :8080 --chdir /home/user/AMS -w AMS.wsgi
[pid: 31757|app: 0|req: 2/2] 203.94.69.162 () {42 vars in 695 bytes} [Mon Apr 17 10:34:02 2017] GET /ams_tools/ => generated 146 bytes in 76 msecs (HTTP/1.1 200) 2 headers in 80 bytes (1 switches on core 0)
但是,当我启动uswgi作为服务时,我得到了以下错误

我可以看到它没有使用正确的python版本。我试图将home位置设置为/home/dhanushka/.virtualenvs/amsAPI,但是我得到了
ImportError: No module named site
您需要告诉您的
uWSGI
到venv
的路径。在http://uwsgi-docs.readthedocs.io/en/latest/Options.html#virtualenv
pythonpath参数中的路径必须指向virtualenv中的python3解释器:
/[环境的绝对路径]/bin/python3
