使用capistrano进行部署。 一切顺利,然后在部署时:启动(部署:冷却期间),它会产生错误:

尝试通过ssh运行命令(sh -c'/etc/init.d/unicorn_appname start'),我遇到了同样的错误。
可能是什么原因?

如果您从相对路径与绝对路径进行符号链接,则很可能会发生这种情况。尝试通过提供绝对路径再次符号链接。
chmod +x /home/username/app/app_name/current/config/unicorn_init.sh
ln -nfs /home/username/app/app_name/current/config/unicorn_init.sh /etc/init.d/unicorn_app_name
看看是否有效

谢谢大家的建议。 问题终于解决了。 问题结果是从Windows机器部署 - .sh文件具有Windows样式的行结尾,并且unix无法正确读取。 解决方案是相应地更改IDE设置(对于Rubymine:File-&gt; Settings-&gt; Code style-&gt; General-&gt; Line separator-&gt; unix)并重新创建文件。然后: git add。 git commit -m“fix” git push cap deploy:setup cap deploy:cold
完成! 再次感谢eveybody!
P.S。:是否有人知道为什么资产管道在部署后无法运作?

你的capistrano部署:启动任务应该阅读
task :start, :roles => :app, :except => { :no_release => true } do
run "/etc/init.d/unicorn start"
end
除非你故意命名你的unicorn init文件/etc/init.d/unicorn_appname。
capistrano部署用户是否对该文件具有执行权限?
