通過 init.d 腳本啟動 UWSGI 以退出程式碼 1 退出並顯示“失敗”，但程序執行正常
在這被標記為重複之前，我閱讀了這個問題；但是添加
logfile2並沒有改變任何東西。我目前正在創建一個使用 UWSGI 執行 Python 堆棧的 docker 容器，為此我使用預設的 Debian 安裝的 uwsgi 作為
init.d腳本，並使用pip.但是，每當我啟動服務時，它都會輸出一個錯誤，指出腳本無法啟動，但是當我嘗試向伺服器發出請求 (
localhost:5000) 或嘗試查看程序是否正在執行ps aux | grep -i uwsgi時，伺服器執行得很好。我的意思的例子：
root@f16b3268a956:~# /etc/init.d/uwsgi start [FAIL] Starting app server(s): uwsgi -> ! failed!但是，如果我查看正在執行的程序
root@f16b3268a956:~# ps aux | grep -i uwsgi user 984 0.1 2.8 235284 57876 ? S 14:15 0:00 /usr/local/bin/uwsgi --ini /usr/share/uwsgi/conf/default.ini --ini /etc/uwsgi/apps-enabled/portal.ini --daemonize /var/log/uwsgi/app/portal.log user 1009 0.0 2.7 253204 57040 ?

[uwsgi] http-socket = localhost:5000 http-websockets = true chmod-socket=775 chdir = /home/user/ master = true binary-path = /usr/local/bin/uwsgi virtualenv = /home/user/portal module = portal.server:app uid = user gid = user processes = 1 gevent = 1000 logfile2 = /tmp/test.pid logto = /var/log/uwsgi/app/portal.log查看日誌文件也沒有顯示任何奇怪的東西：

我最終通過基於以下 docker 鏡像解決了這個問題，該鏡像使用 supervisord 而不是 init.d 程序（沒有 systemctl）。
您需要傳遞
--cap-add SYS_PTRACE到docker run，否則start-stop-daemon將無法檢測到守護程序正在執行並且初始化腳本將失敗。
