apt-get upgrade 出现缺 cPickle，debconf 错误

phpnew — Fri, 26 Jul 2013 05:19:42 +0800

cat /etc/issue Debian GNU/Linux 6.0 \n \l

apt-get update 正常

apt-get upgrade 出现问题 ```bash File "/usr/bin/pycompile", line 38, in from debpython.pydist import PUBLIC_DIR_RE File "/usr/share/python/debpython/pydist.py", line 29, in from debpython.tools import memoize File "/usr/share/python/debpython/tools.py", line 25, in from cPickle import dumps ImportError: No module named 'cPickle' dpkg: error processing debconf (--configure): subprocess installed post-installation script returned error exit status 1 configured to not write apport reports Errors were encountered while processing: debconf E: Sub-process /usr/bin/dpkg returned an error code (1)


python -v发现默认是3版本的
python下载2.7.5源码编译
然后 python -v 
```bash
Python 2.7.5 (default, Jul 26 2013, 04:26:24)

但是问题依然同上

apt-get -f install 同上上

google 半天，没能解决，特来请教该什么办

Ubuntu Server + nginx + unicorn tcp socket 方式如何设置运行多个 app

phpnew — Sat, 11 May 2013 00:44:58 +0800

疑问一 tcp socket 和 unix socket 差别的问题

我抄配置用 unix socket 失败 改用 tcp socket 却成功，不知道原因是什么 虽然这样搞定一个 app，但是第二个 app 就没招了

vim /home/rails/hellworld/config/unicorn.rb

module Rails
  class <<self
    def root
      File.expand_path("../..", __FILE__)
    end
  end
end
puts Rails.root
rails_env = ENV["RAILS_ENV"] || "production"

preload_app true
working_directory Rails.root
pid "#{Rails.root}/tmp/pids/unicorn.pid"
stderr_path "#{Rails.root}/log/unicorn.log"
stdout_path "#{Rails.root}/log/unicorn.log"

listen 5000, :tcp_nopush => false   # 

listen "/tmp/unicorn.ruby-china.sock"
worker_processes 6
timeout 120

if GC.respond_to?(:copy_on_write_friendly=)
  GC.copy_on_write_friendly = true
end

before_exec do |server|
  ENV["BUNDLE_GEMFILE"] = "#{Rails.root}/Gemfile"
end

before_fork do |server, worker|
  old_pid = "#{Rails.root}/tmp/pids/unicorn.pid.oldbin"
  if File.exists?(old_pid) && server.pid != old_pid
    begin
      Process.kill("QUIT", File.read(old_pid).to_i)
    rescue Errno::ENOENT, Errno::ESRCH
      puts "Send 'QUIT' signal to unicorn error!"
    end
  end
end

listen 5000, :tcp_nopush => false # 这个 listen 5000 是咋回事，我看不少 listen 3000，随意指定一个不冲突端口都可以吧我测试 5001 5002 都可以

我 tmp 下创建了 listen "/tmp/unicorn.ruby-china.sock" chown www:wwww 也 chmod 777 了 nginx 也

upstream unicorn_server {
       server unix:/tmp/unicorn.ruby-china.sock fail_timeout=0;
    }

/usr/local/rvm/gems/ruby-1.9.3-p374/gems/unicorn-4.6.2/lib/unicorn/socket_helper.rb:134:in `bind_listen': socket=/tmp/ruby-china.sock specified but it is not a socket! (ArgumentError)
```ruby

后来我想起了tcp socket， 
```ruby
listen "/tmp/unicorn.ruby-china.sock" 替换为 listen '127.0.0.1:8080'

nginx.conf 更改 upstream

upstream unicorn_app1{
       server 127.0.0.1:8080 fail_timeout=0;
    }

然后 RAILS_ENV=production bundle exec unicorn_rails -c config/unicorn.rb -E production -D 第一 app 正常了问题是我不知道为咋 unix socket 不行，tcp socket 却可以，发生了什么问题？？？是我 nginx 编译问题，还是我配置出问题？

问题 2 用 tcp socket 如何跑多个运用直接复制 app1 的会变成访问两个域名，都跑到第一个运行的 app 上

我尝试修改第二 app2 unicorn.rb

listen 5077, :tcp_nopush => false #用不同端口，这个端口好像随便不冲突的都可以
listen '127.0.0.1:3000'  #换一个3000的

nginx.conf app2

upstream unicorn_app2{
       server 127.0.0.1:3000 fail_timeout=0;
    }

然后 RAILS_ENV=production bundle exec unicorn_rails -c config/unicorn.rb -E production -D

现在是第二个 app 正常访问，但是内容跑到第一个上面去 同时第一个 app 不正常了 “We're sorry, but something went wrong.”

问题就是用 tcp socket 方式如何设置跑多个运用一台服务器上，127.0.0.1 的除了换端口不知道用什么办法求助

Ubuntu Server + nginx + unicorn 遇到问题

phpnew — Fri, 19 Apr 2013 21:12:20 +0800

网页一直是 502 Bad Gateway

Ubuntu 12.04 ruby 1.9.3p392 (2013-02-22 revision 39386) [x86_64-linux] Rails 3.2.13 以上参考 wiki 部署 http://ruby-china.org/wiki/install_ruby_guide 之前一直用 centos 部署 php，最近刚刚开始尝试使用 ubuntu

账号 rails /home/rails/hellworld rails new helloworld，建立项目，scaffold home, rake db:migrate rails s，利用 WEBrick，ip:3000 访问正常

==========上面很简单，到 unicorn 和 nginx 就难死了，接下来一大堆坑了========== Nginx apt-get install nginx

Unicorn gem install unicorn

搞了两天没搞定，就直接 copy ruby-china 的 unicron.rb，稍微改动一点点

vim /home/rails/hellworld/config/unicorn.rb

module Rails
  class <<self
    def root
      File.expand_path("../..", __FILE__)
    end
  end
end
puts Rails.root
rails_env = ENV["RAILS_ENV"] || "production"

preload_app true
working_directory Rails.root
pid "#{Rails.root}/tmp/pids/unicorn.pid"
stderr_path "#{Rails.root}/log/unicorn.log"
stdout_path "#{Rails.root}/log/unicorn.log"

listen 5000, :tcp_nopush => false

listen "/tmp/unicorn.ruby-china.sock"
worker_processes 6
timeout 120

if GC.respond_to?(:copy_on_write_friendly=)
  GC.copy_on_write_friendly = true
end

before_exec do |server|
  ENV["BUNDLE_GEMFILE"] = "#{Rails.root}/Gemfile"
end

before_fork do |server, worker|
  old_pid = "#{Rails.root}/tmp/pids/unicorn.pid.oldbin"
  if File.exists?(old_pid) && server.pid != old_pid
    begin
      Process.kill("QUIT", File.read(old_pid).to_i)
    rescue Errno::ENOENT, Errno::ESRCH
      puts "Send 'QUIT' signal to unicorn error!"
    end
  end
end

创建一下

sudo touch /tmp/unicorn.ruby-china.sock
sudo chown rails /tmp/unicorn.ruby-china.sock

’‘’

编辑nginx.conf
sudo vim /etc/nginx/nginx.conf
```BashLexer
user rails;
worker_processes 1;
pid /var/run/nginx.pid;

events {
  worker_connections  1024;
  accept_mutex off;
}

http {
          include mime.types;
  default_type application/octet-stream;
  access_log /var/log/nginx/nginx.access.log combined;

  sendfile on;
  tcp_nopush on;
  tcp_nodelay off;

  gzip on;
  gzip_http_version 1.0;
  gzip_proxied any;
  gzip_min_length 500;
  gzip_disable "MSIE [1-6]\.";
  gzip_types text/plain  text/css
             text/comma-separated-values
             text/javascript application/x-javascript
             application/atom+xml;




     upstream unicorn_server {
       server unix:/tmp/unicorn.ruby-china.sock fail_timeout=0;
    }

    server {
        listen       80;
        server_name  www.ruby1.com ruby1.com;
        client_max_body_size 4G;
        root /home/rails/hellworld/public;

        #access_log  logs/host.access.log  main;

        location / {
        proxy_redirect off;
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-Host $host;
        proxy_set_header X-Forwarded-Server $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_buffering on;
        proxy_pass http://unicorn_server;
        }

    }
}

域名 rub1.com 只是测试的，vim /etc/hosts 都改回指向 127.0.0.1

浏览器测试 网页一直是 502 Bad Gateway

tail -f /var/log/nginx/error.log 跟踪 nginx error.log

rver: www.ruby1.com, request: "GET /favicon.ico HTTP/1.1", upstream: "http://unix:/tmp/unicorn.ruby-china.sock:/favicon.ico", host: "www.ruby1.com"

搞了好久都没法搞定求高手指点
