当部署时请求到达我的服务器时，它失败了。我在 AWS EC2 中使用 Ubuntu。当我使用 Elastic Load Balancer 时，我已经尝试从 Load Balancer 注销并再次注册我的实例，以便同时启动独角兽服务器。同样在开始独角兽之前，我正在删除unicorn.pid
inst=$(ec2metadata --instance-id)`
aws elb deregister-instances-from-load-balancer --load-balancer-name my_load_balancer_name --instances $inst
echo "Server deregistered from Load Balancer"
sleep 10s
file="/home/ubuntu/pids/unicorn.pid"
if [ -f $file ];
then
echo "File found:"
ls /home/ubuntu/pids/
rm ~/pids/unicorn.pid
echo "unicorn.pid removed"
ls /home/ubuntu/pids/ #cross-checking the removal of the unicorn.pid
echo "if you see \"unicorn.pid removed\" message just above this line, it means unicorn.pid removed successfully"
else
echo "$file not found"
fi
RAILS_ENV=qa bundle exec unicorn -c config/unicorn.rb -D #this command is giving error "[stderr]master failed to start, check stderr log for details" `
非常感谢任何帮助。
