我尝试以 systemd 形式运行 Snorby，但脚本无法正确启动

我可以在 Snorby 文件夹中在命令行上执行 bundle exec rails server -e development -b 0.0.0.0 而不会出现任何问题，但是当我将它放入脚本中并使用 systemctl 执行时，它无法正常工作。

[Service] WorkingDirectory=/tmp/snorby Environment=RAILS_ENV=development ExecStart=/usr/local/rbenv/shims/bundle exec rails server -d -b 0.0.0.0

状态输出

snorby.service - Snorby ConfiServ

答案1

就我而言，当我在脚本前使用“bash -l”时，它起作用了，如下所示。

ExecStart=/bin/bash -l'你的 ruby​​ 命令或脚本'

我猜 centos 7 在使用 systemd 加载 ruby​​ 环境变量时遇到了一些问题。不过它在没有 -l 选项的 ubuntu 上也能正常工作。

答案2

我明白了 - 你需要在 Systemd 上启动 Thin
