节点服务活动（运行）但不可用

  • 772

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，但是它仍然显示节点服务实际上没有运行。

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，它没有按预期运行。

服务状态

寻找8000端口

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： Starting node application with nodeworks but not when starting it with/usr/bin/node

services node.js

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

    该命令node在这里起作用，因为该命令已通过运行链接到/root/.nvm/versions/node/v6.7.0/bin/nodeinstalled 。nvmv6.7.0

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

    注意： 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“stock”节点安装。
