Puma的systemd脚本无法启动Puma。

我一直从多个来源复制和粘贴以下 Puma 系统启动脚本的片段，但它无法正常工作。系统是 Debian 9.6，用户 rails 已经通过 rvm 安装了 Ruby。用户 rails 可以运行命令 RAILS_ENV=production bundle exec puma -C /var/www/test-optimum/current/config/puma.rb --daemon。

这个脚本有什么问题吗？

[Unit]
Description=Test Puma HTTP Server
After=network.target

[Service]
Type=simple
User=rails
WorkingDirectory=/var/www/test-optimum/current
ExecStart=/bin/bash -lc 'RAILS_ENV=production bundle exec puma -C /var/www/test-optimum/current/config/puma.rb --daemon'
ExecStop=/home/rails/.rvm/bin/rvm default do bundle exec pumactl -S /var/www/test-optimum/shared/tmp/pids/puma.pid stop

PIDFile=/var/www/test-optimum/shared/tmp/pids/puma.pid
Restart=always

[Install]
WantedBy=multi-user.target

尝试使用systemctl start puma启动时，出现以下错误：

这是解决方案：

[Unit]
Description=Test Puma HTTP Server
After=network.target

[Service]
Type=simple
User=rails
WorkingDirectory=/var/www/test-optimum/current
ExecStart=/bin/bash -lc 'RAILS_ENV=production bundle exec puma -C /var/www/test-optimum/current/config/puma.rb'
ExecStop=/home/rails/.rvm/bin/rvm default do bundle exec pumactl -S /var/www/test-optimum/shared/tmp/pids/puma.pid stop

PIDFile=/var/www/test-optimum/shared/tmp/pids/puma.pid
Restart=always

一个改进的解决方案可能是：
[Unit]
Description=Test Puma HTTP Server
After=network.target

[Service]
Type=simple
User=rails
WorkingDirectory=/var/www/test-optimum/current
ExecStart=/home/rails/.rvm/bin/rvm default do bundle exec puma -C /var/www/test-optimum/current/config/puma.rb --daemon
ExecStop=/home/rails/.rvm/bin/rvm default do bundle exec pumactl -S /var/www/test-optimum/shared/tmp/pids/puma.pid stop

PIDFile=/var/www/test-optimum/shared/tmp/pids/puma.pid
Restart=always

[Install]
WantedBy=multi-user.target
-1

在我的情况下，我在ExecStart中使用了错误的命令，更新为类似以下内容即可解决问题：ExecStart=/bin/bash -lc 'RAILS_ENV=production bundle exec puma -C /home/ubuntu/rails_current_server/config/puma.rb'
