Systemd 服務啟動失敗並出現 rbenv 環境錯誤

Systemd 服務啟動失敗並出現 rbenv 環境錯誤

用於啟動 Rails 應用程式的服務存在一些問題。 ruby安裝是透過rbenv管理的,服務文件是這樣的:

[Unit]
Description=evr server boot
After=network.target
After=local-fs.target

[Service]
Type=forking
User=pi
Group=pi
WorkingDirectory=/home/pi/evr
ExecStart=/home/pi/.rbenv/bin/rbenv bundle exec rails s -b 192.168.1.66
TimeoutSec=180
RestartSec=180s
Restart=always

[Install]
WantedBy=multi-user.target

當系統啟動時,涉及此服務時會拋出此錯誤:

$ systemctl status evrserver
● evrserver.service - evr server boot
   Loaded: loaded (/etc/systemd/system/evrserver.service; enabled; vendor preset: enabled)
   Active: activating (auto-restart) (Result: exit-code) since Wed 2019-04-03 18:34:22 BST; 2min 51s ago
  Process: 425 ExecStart=/home/pi/.rbenv/bin/rbenv bundle exec rails s -b 192.168.1.66 (code=exited, status=1/FAILURE)
   CGroup: /system.slice/evrserver.service

Apr 03 18:34:22 raspberrypi systemd[1]: Failed to start evr server boot.
Apr 03 18:34:22 raspberrypi systemd[1]: evrserver.service: Unit entered failed state.
Apr 03 18:34:22 raspberrypi systemd[1]: evrserver.service: Failed with result 'exit-code'.

看起來 PATH 存在問題,並且在嘗試執行“rails”命令時失敗。如何避免這種情況,以便服務成功啟動 Rails 應用程式?

答案1

所以這很簡單,是嗎?看起來我忘記了 ExecStart 行中“bundle”之前的“exec”,並且還需要將類型設為“simple”而不是“forking”
