无法为 Nodejs 启动自定义 systemd 服务：未找到节点

我安装了火箭聊天室在我的 Debian Jessie 上，它运行良好，我希望在启动时将其作为服务自动启动。

要手动启动 Rocket.chat，我需要

$ cd /home/hung/Rocket.chat
$ node main.js

这是我的/etc/systemd/system/rocket-chat.service

[Service]
ExecStart=/usr/local/bin/node main.js
Restart=always
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=rocket-chat
User=hung
Group=hung
WorkingDirectory=/home/hung/Rocket.chat

[Install]
WantedBy=multi-user.target

服务未启动：

# systemctl start rocket-chat
# systemctl status rocket-chat
● rocket-chat.service
   Loaded: loaded (/etc/systemd/system/rocket-chat.service; disabled)

这是 /var/log/syslog 中的内容：

/usr/local/bin/node存在：

$ /usr/local/bin/node --version
v8.9.3

/usr/local/bin/node找不到的问题如何解决？

答案1

ExecStart应该

ExecStart=/usr/local/bin/node /home/hung/Rocket.chat/main.js

这是我的文件的最终版本（/etc/systemd/system/rocketchat.service）：

[Unit]
Description=RocketChat Server
After=network.target remote-fs.target nss-lookup.target mongod.target apache2.target

[Service]
ExecStart=/home/hung/.nvm/versions/node/v8.9.3/bin/node /var/www/chat/Rocket.Chat/main.js
Restart=always
RestartSec=10
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=rocketchat
Environment=NODE_ENV=production
Environment=PORT=3001
Environment=ROOT_URL=https://domain.com/
Environment=MONGO_URL=mongodb://localhost:27017/rocketchat
Environment=MAIL_URL='smtp://user@domain:password@domain:587/'

[Install]
WantedBy=multi-user.target

启动服务：sudo systemctl start rocketchat

开机启动：sudo systemctl enable rocketchat
