Couchdb 服務在啟動後關閉一秒鐘

我在執行 couchdb 服務時遇到問題。當我啟動它時，它只存在一秒鐘左右就會自行關閉。這是一個範例 - 首先是一個狀態命令，顯示它處於非活動狀態。啟動時它聲稱正在執行，下一個狀態命令表示它處於活動狀態，一秒鐘後發出一個新狀態表示它失敗了。這是怎麼回事？

我找不到任何日誌文件/stdout/stderr。似乎有些東西正在嘗試重新啟動 couchdb，但基於“couchdb.service: Service hold-off time over, schedule restart.”而失敗。但為什麼？

問題在以下幾行中定義：

jan. 28 23:06:34 myPC couchdb[3071]: =ERROR REPORT==== 29-Jan-2016::00:06:34 ===
jan. 28 23:06:34 myPC couchdb[3071]: File operation error: eacces. Target: /lost+found/ebin. Function: read_file_in...erver.
jan. 28 23:06:34 myPC couchdb[3071]: =ERROR REPORT==== 29-Jan-2016::00:06:34 ===
jan. 28 23:06:34 myPC couchdb[3071]: File operation error: eacces. Target: /root/ebin. Function: read_file_info. Pr...erver.

它嘗試使用已編譯的 CouchDB 光束文件查找 ebin 目錄，但由於權限問題 (eacces) 而失敗。但是，原因不在於權限，而在於路徑：為什麼要在 /root 目錄中查找梁？可能是因為它在檢查所有其他選項時失敗（並且該服務以 root 身份執行，這是不好的）。

唯一可能的答案是您的 $ERL_LIBS 路徑配置錯誤。需要為像這樣的梁命令行參數設置它-env ERL_LIBS $ERL_LIBS:/usr/lib64/couchdb/erlang/lib- 請注意，此處的路徑應根據您的安裝設置。
