反馈 把我安装 ruby-china 的详细步骤发上来，寻求问题解决
系统：ubuntu 11.10 ruby 版本：1.9.2 rails 版本：3.1.1 mongodb 版本：2.0.1 redis 版本：2.4.2
全部从全新系统开始，搞了两遍，依然没有解决，以下是我的安装步骤：
基本设置及常用软件安装
# 建立程序安装目录
$ cd ~
$ mkdir apps
# 建立工作目录
$ cd ~
$ mkdir workspace
# 安装常用库及软件
$ sudo apt-get install git git-core vim curl libxml2-dev libxslt-dev make gcc g++
Ruby on Rails 安装
1.Ruby install
$ sudo apt-get install ruby1.9.2-full
# 查看当前系统ruby版本
$ ruby -v
# ruby 1.9.2p290 (2011-07-09 revision 32553) [i686-linux]
2.Gem update
$ sudo gem install rubygems-update
$ sudo update_rubygems
$ gem -v
# 1.8.11
# 将下面语句写入~/.gemrc 禁止Gem安装本地文档
gem: --no-ri --no-rdoc```
3.Rails install
```bash
$ sudo gem install rails
$ rails -v
# Rails 3.1.1
4.Other install
$ sudo apt-get install sqlite3 libsqlite3-dev
$ sudo gem install sqlite3-ruby
MongoDB 安装
1.install
$ cd ~/apps
$ wget http://fastdl.mongodb.org/linux/mongodb-linux-i686-2.0.1.tgz
$ tar xzf mongodb-linux-i686-2.0.1.tgz
$ sudo ln -s ~/apps/mongodb-linux-i686-2.0.1/bin/mongod /usr/bin/mongod
$ sudo ln -s ~/apps/mongodb-linux-i686-2.0.1/bin/mongo /usr/bin/mongo
# create data directory
$ sudo mkdir -p /data/db
# set permission
$ sudo chmod 755 -R /data/db
- run server
bash $ sudo mongod # 如果数据库目录不想建立在/data/db，可以用--dbpath参数指定目录
3.test
$ mongo
> db.foo.save( { a : 1 } )
> db.foo.find()
Redis 安装
-
install
$ cd ~/apps $ wget http://redis.googlecode.com/files/redis-2.4.2.tar.gz $ tar xzf redis-2.4.2.tar.gz $ cd redis-2.4.2 $ sudo make $ sudo make install -
run server
$ sudo src/redis-server -
test
$ sudo src/redis-cli redis> set foo bar OK redis> get foo "bar"
安装 ruby-china 1.Node.js install
$ sudo apt-get install libssl-dev apache2-utils
$ cd ~/workspace
$ git clone git://github.com/ry/node.git
$ cd node
$ ./configure
$ make
$ sudo make install
- Deploy ruby-china
bash $ sudo gem install thin execjs therubyracer $ sudo gem install nokogiri -v '1.5.0' $ cd ~/workspace $ git clone https://github.com/huacnlee/ruby-china.git $ cd ruby-china $ cp config/config.yml.default config/config.yml $ cp config/mongoid.yml.default config/mongoid.yml $ cp config/redis.yml.default config/redis.yml $ sudo bundle install $ sudo rake assets:precompile $ thin start -O -C config/thin.yml $ ./script/resque start
运行到最后第三部（sudo rake assets:precompile）时，出现问题如下：
bindiry@bindiry-ubuntu:~/workspace/ruby-china$ sudo rake assets:precompile

之前已经发过帖子 http://ruby-china.org/topics/55 里面@huacnlee @cqpx @Rei 给出的介绍方法均尝试过，都没有解决，所以开个新帖，把我的操作步骤仔细说一下，哪位同学帮我解决一下？
用源里面或者 mongodb 维护的 deb 看看
http://www.mongodb.org/display/DOCS/Ubuntu+and+Debian+packages
悲剧了，换上 ubuntu server，用 root 用户，mongodb 也用的 deb 版安装，还是出同样的错误。。。 郁闷了。。

确定 mongodb 和 redis 都没问题后的结果。。。

这个 ubuntu 安装有点..... 给后面看到的提个醒
- sudo 能不用就别用，后面都是麻烦，特别是 rvm 的
- 初学的自己调试的，真不用编译安装，等你有生产环境再担心生产环境的事。（和过早优化，过早重构一个道理）
- 最后那个 precompile，版本不一致，要把 sudo 换成 bundle exec，通常建议加个 alias be，这个有多个项目的时候，经常会用到。
开发环境在 ubuntu 下配好了，简单看看还挺好的，回头去 mac 下再配一下，然后，看看有什么 issue 可以接。
你把系统环境重新安装，Ruby 用 RVM 来安装，MongoDB, Redis 用 http://github.com/huacnlee/init.d 来安装（Ubuntu Server 9.04)
重装了 MongoDB 和 Redis 后重新安装初始化 ruby-china 项目在最后两步遇到问题

遇到和你一样的问题，这个 assets 的问题影响不大。我跳过这一步后遇到了另一个问题，即是在运行./script/resque start 时报错了：
MONGODB [WARNING] Please note that logging negatively impacts client-side performance. You should set your logging level no lower than :info in production. /home/administrator/.rvm/gems/ruby-1.9.2-p290/gems/mongo-1.5.2/lib/mongo/connection.rb:413:in `connect': Failed to connect to a master node at 127.0.0.1:27017 (Mongo::ConnectionFailure) 我去 stackoverflow.com 里去查过。在 mongdb 官网去查过，到 mongoid 去查过，直接在 google 里也查过，硬是没找到解决办法.... 有没有谁知道这个应该怎么弄？
我将出现这个 mongodb warning 的问题提交到 github.com 了，希望能有找到解决办法。 https://github.com/huacnlee/ruby-china/issues/175
#31 楼 @suffering Failed to connect to a master node at 127.0.0.1:27017 (Mongo::ConnectionFailure) MongoDB 没有启动
好吧，问题诡异地得到了解决。我所做的事情，就是重新运行起 mongodb，与 redis，并保持其持续运行。在运行rake assets:precompile与./script/resque start时虽然依旧出现了set your logging level no lower than :info in production,但是，却是不影响其运行。
