我剛剛通過自己的幫助設法使我的服務狀態處於活動狀態，但是似乎節點服務實際上並未執行。

簡而言之，我知道我的節點應用程序正在執行，但出於所有密集目的，它並沒有發揮應有的作用。

服務狀態

尋找8000埠

root@server:/etc/systemd/system# netstat -tulpn | grep 8000
root@server:/etc/systemd/system# 

但是我可以看到節點應用程序正在執行

root@server:/etc/systemd/system# ps ax | grep node
18799 ?        Ssl    0:00 /usr/bin/node /var/www/gwart/mediawiki/extensions/VisualEditor/parsoid/bin/server.js

我相信它與這個問題有關： Starting node application with nodeworks but not when started it with/usr/bin/node

/usr/bin/node似乎是包管理器安裝的可執行節點，v4.2.6對於parsoid.

該命令node在這里工作，因為該命令通過執行連結到/root/.nvm/versions/node/v6.7.0/bin/node安裝。nvm``v6.7.0

要解決此問題，請創建指向目前 nvm 版本的符號連結（以便在更新時能夠輕鬆調整）並在.service文件中使用該路徑。

注意： 我不建議刪除符號連結或文件/usr/bin/node以便在那裡放置具有該名稱的符號連結，因為這可能會干擾“股票”節點安裝。
