用 Jenkins 做的服务器工程的构建，构建中权限问题怎么解决

liguangsong — Tue, 19 Jan 2016 14:07:24 +0800

用 jenkins 做的服务器工程的构建在构建时加上了一个 execute shell 步骤其中执行

bundle install 
bundle exec rake assets:precompile RAILS_ENV=production

构建中发生错误

rake aborted!
Errno::EACCES: Permission denied - /var/lib/jenkins/workspace/bookkeeper_map/tmp/cache/assets/production/sprockets/v3.0/WScdt_VRi73A4j9G5G1M-1gORwVn1JYvfmJNvcPYCTE.cache

这是哪里的问题

gem “weixin_authorize” 出现错误{"errcode":45009,"errmsg":"api freq out of limit"}

liguangsong — Tue, 08 Dec 2015 16:27:32 +0800

现在网站的人上去了，出现请求 access_token 超过最大值，我用的是 weixin_authorize，我的代码如下：麻烦大神们看看，是哪里出错造成了，请求超出最大值

WeixinAuthorize.configure do |config|
  config.rest_client_options = {timeout: 50, open_timeout: 50, verify_ssl: true}
end

这里的 timeout 和 open_timeout 不知道是怎么使用的，没有查到说明

module WeiXin
  def self.client
    $client = WeixinAuthorize::Client.new(APP_ID, APP_SECRET)
  end
end

require './app/service/weixin/js_sdk'
  def get_ticket
   if !$client || !$client.is_valid?
     $client = WeiXin.client()
   end
   # $client = WeiXin.client()
   sign_package = $client.get_jssign_package(params[:url])
   render :json => {:sign_package => sign_package}
 end

数据怎么查询才能优化查询速度

liguangsong — Tue, 17 Nov 2015 23:26:45 +0800

我现在有一个用户表里面有个学历这个属性，然后我有一个文章表，use：has_many: articles 我应该怎么去实现查找全部发布者学历大于本科的文章我现在是这么做的

Article.where(opend_id: user.where('大于本科').pluck(article_id:)).order("updated_at desc").paginate(:page => params[:page], :per_page => 8)

但是感觉如果数据多了，感觉这个过程会很浪费时间不知道怎么做才好

rails 里怎么实现轮询

liguangsong — Mon, 19 Oct 2015 10:47:21 +0800

想在 ruby 里实现以下功能，每隔 10 分钟向里另一个服务器发送请求，请求数据，应该怎么实现

form_tag 提交时报错 Can't verify CSRF token authenticity 怎么解决

liguangsong — Thu, 24 Sep 2015 16:41:28 +0800

Parameters: {"utf8"=>"✓", "authenticity_token"=>"URxRok8OUG3ldCKKzVWeWgF4kZ+ba5z6fLfI/VLPydJNvdv63FMB8/sEA2wg1xFGsbp44HcKrKNxPQEd0ciIVQ==", "name"=>"1", "password"=>"[FILTERED]", "commit"=>"登录"}
Can't verify CSRF token authenticity

以前都是 skip_before_filter :verify_authenticity_token 跳过验证，但是不知道原理，感觉会不会不安全谁能给点建议

部署到服务器 asset 里的 css 和 js 时不时加载不上，内存不足么？

liguangsong — Mon, 31 Aug 2015 08:37:18 +0800

部署到服务器上后，一开始还能加载的上，过段时间就加载不上了，然后不用管一会有恢复正常了，这是哪里的问题，和缓存或者内存有关系么

crontab 没有执行 rackup 的权限？

liguangsong — Fri, 28 Aug 2015 14:18:10 +0800

这两天做一个聊天服务器，好不容易放到服务器上了，但是我是这么启动的

rackup faye.ru -s thin -E production -o 0.0.0.0 &

怕他自己挂掉，让 crontab 轮询去，执行文件

faye.sh
#!/bin/sh
echo "ddssf" >> /var/ssss.tx
DTTERM=$(ps -ef|grep thin | grep -v "grep :9292"|wc -l)
if [ $DTTERM = 2 ]; then
cd /var/www/html/jenkins/xxxx/xxxxx;
rackup faye.ru -s thin -E production -o 0.0.0.0 &
echo "ok" >> /var/ssss.tx
fi
```
结果文件执行没问题，但是服务就是起不来
手动执行 ,就启动了
```
sh faye.sh
```
亲们，这是怎么回事？权限问题？

cron.log写着

Aug 28 14:07:01 iZ28tq0g0rnZ CRON[20947]: (root) CMD (bash /etc/faye_client.sh)

Faye 部署到服务器上前台握手失败

liguangsong — Wed, 26 Aug 2015 10:27:52 +0800

启动 faye.ru rackup faye.ru -s thin -E production

本地测试挺好的，但是部署到服务就完蛋了

WebSocket connection to 'ws://blind.codefordream.com:9292/faye' failed: Error in connection establishment: net::ERR_CONNECTION_REFUSED

这是 faye.ru 代码

require 'faye'
require File.expand_path('../config/initializers/faye_token.rb', __FILE__)
require 'active_record'
require 'mysql2'
require 'yaml'
Faye::WebSocket.load_adapter('thin')
RAILS_ENV = ENV['RACK_ENV']
# require File.expand_path('../app/models/user_chat_room.rb', __FILE__)
require File.expand_path('../app/models/user_chat_list.rb', __FILE__)
require File.expand_path('../app/models/chat_message.rb', __FILE__)
require File.expand_path('../app/models/user_chat_online.rb', __FILE__)

environment = ENV['RACK_ENV'] || 'production'
dbconfig = YAML.load(File.read('config/database.yml'))
ActiveRecord::Base.establish_connection(dbconfig[environment])
faye_server = Faye::RackAdapter.new(:mount => '/faye', :timeout => 60)
class MarkOnline
  def incoming(message, callback)
    faye_client ||= Faye::Client.new('http://localhost:9292/faye')

    if message['channel'].match('/chat/*')
      to_is_online= UserChatOnline.check_on_line(message['data']['to'], message['data']['from'], message['data']['content'], message['clientId'])

      if !to_is_online
        UserChatList.change_chat_list(message['data']['to'], message['data']['from'], "false")
        ChatMessage.creat_new_chat_message(message['data']['from'], message['data']['to'], message['data']['content'])
      end
    end

    if message['channel'] == '/meta/subscribe'
      UserChatOnline.create_on_line_user(message['data']["from"], message['clientId'])
    end

    if message['channel'] == '/meta/disconnect'
      UserChatOnline.remove_on_line_user(message['clientId'])
    end

    callback.call(message)
  end
end

faye_server.on(:disconnect) do |client_id|
  UserChatOnline.remove_on_line_user(client_id)
end


faye_server.add_extension(MarkOnline.new)
run faye_server

这是前台配置

var client = new Faye.Client('http://' + document.domain + ':9292' + '/faye');
    client.subscribe('/chat/'+user_name, function (data) {
        get_message_from_server(data.from, data.to, data.content);
        show_from_message("from",data.content)
    });
    client.addExtension({
        outgoing: function (message, callback) {
            if (message.channel == '/meta/subscribe') {
                message.data = {from: user_name};
            }
            if (message.channel == '/meta/disconnect') {
                message.data = {from: user_name};
            }
            callback(message);
        }
    });
    window.client = client;

求助，上传照片出现 RequestURITooLarge 错误

liguangsong — Mon, 17 Aug 2015 16:30:20 +0800

function save_notes(image){
    $.ajax({
        url:"/save_notes",
        data:{
            image:image,
            text:localStorage.getItem("post_text")||""
        },
        success:function(){

        },
        error:function(){

        }
    })
}

本地测试出现

ERROR WEBrick::HTTPStatus::RequestURITooLarge 
ERROR TypeError: can't convert nil into an exact number

感觉应该设定允许上传的文件最大范围，但不知道怎么实现

如何加快首页加载？求助

liguangsong — Mon, 27 Jul 2015 17:18:26 +0800

bundle exec rake assets:precompile 编译后的 application 有 300k(就只有 bootstrap、jquery、kindeditor) 加载的时间有两秒，再上图片的渲染感觉网页加载特别慢，求大神们指点下，我在 nginx 是这样设置的

http {
     passenger_root /usr/local/rvm/gems/ruby-2.0.0-p598/gems/passenger-4.0.59;
    passenger_ruby /usr/local/rvm/gems/ruby-2.0.0-p598/wrappers/ruby;
    passenger_nodejs /root/.nvm/v0.10.36/bin/node;
    include       mime.types;
    default_type  application/octet-stream;



    sendfile        on;

    keepalive_timeout  65;

    gzip  on;
    gzip_min_length 1k;
    gzip_buffers 4 16k;
    gzip_comp_level 5;
    gzip_types text/plain application/x-javascript text/css application/xml text/javascript application/x-httpd-php;
}

server {
        listen       90;
        server_name  www.xxxx.cn;


    root /var/lib/jenkins/workspace/xxxx/public;
        passenger_enabled on;
    location ~* \.(js|css)$ {
        expires 30d;
    }
    location ~* \.(jpg|png|jpeg|gif){
        expries 30d;
    }
    location ^~ /assets/ {
        expries 30d;
    }

}

我应该怎么优化下才好
