ruby-on-rails - 无法启动 Phusion Passenger 看门狗

Question

我正在尝试使用 passenger 和 nginx 运行 rails。 Nginx 不会重定向到我的 Rails 应用程序，而是继续到其默认的 index.html 页面，我得到了这个错误:

Unable to start the Phusion Passenger watchdog because it encountered the following error during startup: Cannot create a subdirectory inside instance registry directory /tmp: No such file or directory (errno=2) (-1: Unknown error)

Answer 1

尝试

echo 0 | sudo tee /proc/sys/kernel/yama/ptrace_scope
echo 1 | sudo tee /proc/sys/kernel/yama/ptrace_scope
echo 0 | sudo tee /proc/sys/kernel/yama/ptrace_scope
sudo sh -c 'echo 0 > /proc/sys/kernel/yama/ptrace_scope'
sudo sh -c 'echo 1 > /proc/sys/kernel/yama/ptrace_scope'
sudo netstat -tnlp | grep :22222

祝你好运!
