Question

我一直在复制和粘贴以下puma系统的代码片段，这些脚本片段是从多个来源启动脚本的，但是它不起作用。系统是Debian 9.6，用户rails通过rvm安装了ruby。用户rails可以启动命令RAILS_ENV=production bundle exec puma -C /var/www/test-optimum/current/config/puma.rb --daemon

此脚本有什么问题？

[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

尝试以systemctl start puma开头时，出现以下错误：

Answer 1

此脚本有什么问题？

可能只是服务的类型：

主要PID：3239（代码=已退出，状态= 0 /成功）

似乎主要过程是分叉。尝试使用forking代替simple：https://www.freedesktop.org/software/systemd/man/systemd.service.html#Options

在我的情况下，我在 ExecStart 更新到这样的东西中有错误的命令ExecStart=/bin/bash -lc 'RAILS_ENV=production bundle exec puma -C /home/ubuntu/rails_current_server/config/puma.rb'

Answer 3

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

Answer 4

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

[Install]
WantedBy=multi-user.target
