服务状态

我刚刚通过你们自己的帮助设法使我的服务状态处于活动状态，但是节点服务似乎仍然没有实际运行。

简而言之，我知道我的节点应用程序正在运行，但出于所有密集目的，它没有按应有的方式运行。

寻找端口 8000

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

但是我可以看到节点应用程序正在运行

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

我相信这与这个问题有关： 启动节点应用程序可以node工作，但启动时不可以/usr/bin/node

答案1

/usr/bin/node似乎是由包管理器安装的节点可执行文件，并且v4.2.6对于parsoid.

该命令node在这里起作用是因为该命令是/root/.nvm/versions/node/v6.7.0/bin/node通过nvm运行链接到安装的v6.7.0。

要解决此问题，请创建指向当前 nvm 版本的符号链接（以便能够在更新时轻松调整）并在文件中使用该路径.service。

笔记： 我不建议删除符号链接或文件/usr/bin/node以便在那里放置具有该名称的符号链接，因为这可能会干扰“库存”节点安装。
