我尝试使用 ruby​​ (1.9.3-rc1)、rails、capistrano、nginx 和 unicorn 在我的 vps（Ubuntu 12.04 服务器（64 位））上部署 2 天。

我还遵循 Ryan Bates 的 railscast 教程，展示了如何从头开始在 VPS 上进行部署。

实际上 cap deploy:cold 命令似乎可以正常工作（与所有其他命令一样），但是当我尝试访问我的 url 时，我遇到了“我们很抱歉，但出了点问题”=> Rails 的默认错误页面。

在我的生产日志中，我得到：

所以我查看了我的独角兽日志，我发现了这个：

一遍又一遍 ...

所以这是我的配置：

我的独角兽.rb：

root = "/home/deployer/apps/avocat-immo/current"
working_directory root
pid "#{root}/tmp/pids/unicorn.pid"
stderr_path "#{root}/log/unicorn.log"
stdout_path "#{root}/log/unicorn.log"
listen "/tmp/unicorn.avocat.sock"
worker_processes 2
timeout 30

这是我的 unicorn_init.sh

#!/bin/sh
set -e

# Feel free to change any of the following variables for your app:
TIMEOUT=${TIMEOUT-60}
APP_ROOT=/home/deployer/apps/avocat-immo/current
PID=$APP_ROOT/tmp/pids/unicorn.pid
CMD="cd $APP_ROOT; bundle exec unicorn -D -c $APP_ROOT/config/unicorn.rb -E production"
AS_USER=deployer
set -u

OLD_PIN="$PID.oldbin"

sig () {
  test -s "$PID" && kill -$1 `cat $PID`
}

oldsig () {
  test -s $OLD_PIN && kill -$1 `cat $OLD_PIN`
}

run () {
  if [ "$(id -un)" = "$AS_USER" ]; then
    eval $1
  else
    su -c "$1" - $AS_USER
  fi
}

case "$1" in
start)
  sig 0 && echo >&2 "Already running" && exit 0
  run "$CMD"
  ;;
stop)
  sig QUIT && exit 0
  echo >&2 "Not running"
  ;;
force-stop)
  sig TERM && exit 0
  echo >&2 "Not running"
  ;;
restart|reload)
  sig HUP && echo reloaded OK && exit 0
  echo >&2 "Couldn't reload, starting '$CMD' instead"
  run "$CMD"
  ;;
upgrade)
  if sig USR2 && sleep 2 && sig 0 && oldsig QUIT
  then
n=$TIMEOUT
    while test -s $OLD_PIN && test $n -ge 0
    do
      printf '.' && sleep 1 && n=$(( $n - 1 ))
    done
    echo

    if test $n -lt 0 && test -s $OLD_PIN
    then
      echo >&2 "$OLD_PIN still exists after $TIMEOUT seconds"
      exit 1
    fi
    exit 0
  fi
  echo >&2 "Couldn't upgrade, starting '$CMD' instead"
  run "$CMD"
  ;;
reopen-logs)
  sig USR1
  ;;
*)
  echo >&2 "Usage: $0 <start|stop|restart|upgrade|force-stop|reopen-logs>"
  exit 1
  ;;
esac

我努力了

/etc/init.d/unicorn_avocat-immo start
/etc/init.d/unicorn_avocat-immo stop

我也重新启动了 nginx，但似乎没有任何效果。该网站在错误页面上加载不到一秒钟，并且该网站尚未正常工作，因为它应该在生产中。

任何人都可以在这件事上帮助我吗？

在 nginx errors.log 中找到的其他信息

    2013/05/21 12:23:08 [crit] 19097#0: *16 connect() to unix:/tmp/avocat.sock failed (2: No such file or directory) while connecting to upstream, client: **.***.**.***, server: , request: "GET / HTTP/1.1", upstream: "http://unix:/tmp/avocat.sock:/", host: "**.***.**.***"

只需添加 config.log_level = :debugconfig/production.rb

您将在该日志的 log/production.log 粘贴输出中收到错误日志，以便我可以帮助您

也试试rake assets:precompile
