当我在 CentOS 7 上安装 Rocket.Chat 服务器时，我创建了rocketchat.service：

[Unit]
Description=The Rocket.Chat server
After=network.target remote-fs.target nss-lookup.target 
mongod.target[Service]
Type=simple
ExecStart=/usr/local/bin/node /opt/Rocket.Chat/main.js
Restart=always
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=rocketchat
User=root
Environment=MONGO_URL=mongodb://localhost:27017/rocketchat 
ROOT_URL=http://www.leavenotrace.cn PORT=3000
[Install] WantedBy=multi-user.target

当我按下命令时：

systemctl start rocketchat
systemctl status rocketchat

显示以下错误：

Apr 18 11:50:13 VM_56_252_centos systemd[1]: [/etc/systemd/system/rocketchat.service:3] Failed to add dependency on mongod.target[Service], ignoring: Invalid argument

前：

nano /etc/systemd/system/rocketchat.service

它将显示这些错误。

后：

nano /usr/lib/systemd/system/rocketchat.service

在里面写：

  [Unit]
  Description=The Rocket.Chat server
  After=network.target remote-fs.target nss-lookup.target nginx.target mongod.target
  [Service]
  ExecStart=/usr/local/bin/node /opt/Rocket.Chat/main.js
  StandardOutput=syslog
  StandardError=syslog
  SyslogIdentifier=rocketchat
  User=root
  Environment=MONGO_URL=mongodb://localhost:27017/rocketchat ROOT_URL=http://www.leavenotrace.cn:3000/ PORT=3000
  [Install]
  WantedBy=multi-user.target

还行吧。
