無法讓Rails服務器與MySQL一起工作

Question

我想讓我的Rails應用程序與MySQL一起工作，而不是默認的SQLite。我創建了一個新的項目，強制使用似乎正常工作的MySQL。

它添加在寶石文件寶石條目這樣：

source 'https://rubygems.org' 

    gem 'rails', '3.2.13' 

    # Bundle edge Rails instead: 
    # gem 'rails', :git => 'git://github.com/rails/rails.git' 

    gem 'mysql2' 

當我運行bundle命令它表明其用mysql寶石：

Using mysql2 <0.3.11> 

我也配置database.yml文件，像這樣：

development: 
adapter: mysql2 
encoding: utf8 
reconnect: false 
database: dbname 
pool: 5 
username: uname 
password: pass 
host: hostname 

test: 
development: 
adapter: mysql2 
encoding: utf8 
reconnect: false 
database: dbname 
pool: 5 
username: uname 
password: pass 
host: hostname 

production: 
development: 
adapter: mysql2 
encoding: utf8 
reconnect: false 
database: dbname 
pool: 5 
username: uname 
password: pass 
host: hostname 

但是當我嘗試運行軌道服務器我得到這個：

C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/mysql2-0.3.11-x86-mingw32/l ib/mysql2/mysql2.rb:2:in require': 126: The specified module could not be found . - C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/mysql2-0.3.11-x86-min gw32/lib/mysql2/1.9/mysql2.so (LoadError) from C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/mysql2-0.3.11- x86-mingw32/lib/mysql2/mysql2.rb:2:in ' from C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/mysql2-0.3.11- x86-mingw32/lib/mysql2.rb:9:in require' from C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/mysql2-0.3.11- x86-mingw32/lib/mysql2.rb:9:in ' from C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/bundler-1.3.4/ lib/bundler/runtime.rb:72:in require' from C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/bundler-1.3.4/ lib/bundler/runtime.rb:72:in block (2 levels) in require' from C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/bundler-1.3.4/ lib/bundler/runtime.rb:70:in each' from C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/bundler-1.3.4/ lib/bundler/runtime.rb:70:in block in require' from C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/bundler-1.3.4/ lib/bundler/runtime.rb:59:in each' from C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/bundler-1.3.4/ lib/bundler/runtime.rb:59:in require' from C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/bundler-1.3.4/ lib/bundler.rb:132:in require' from C:/Users/n00151956/Desktop/RubyProjects/Demo/config/application.rb: 7:in ' from C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/railties-3.2.1 3/lib/rails/commands.rb:53:in require' from C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/railties-3.2.1 3/lib/rails/commands.rb:53:in block in ' from C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/railties-3.2.1 3/lib/rails/commands.rb:50:in tap' from C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/railties-3.2.1 3/lib/rails/commands.rb:50:in ' from script/rails:6:in require' from script/rails:6:in '

我能得到默認的SQLite運行軌道服務器，但對我的生活，我不能讓它使用MySQL。如果有人能幫助我，這將是很大的幫助！

由於從

Answer 1

1. 下載libmysql.dll的文件 - mysql-connector，並把它放在C：\ RailsInstaller \ Ruby1.9.3 \ BIN應該在這裏Image
2. 打開命令提示符以管理員身份並啓動MySQL服務器方式如下：C：\ Program Files文件\的MySQL \ MySQL服務器5.0 \ BIN \ mysql的

更新

development: 
    adapter: mysql2 
    database: proj_development 
    username: root 
    password: pass 
    host: 127.0.0.1 
    socket: /tmp/mysql.sock 

test: 
    adapter: mysql2 
    database: proj_test 
    username: root 
    password: pass 
    host: 127.0.0.1 
    socket: /tmp/mysql.sock 

production: 
    adapter: mysql2 
    database: proj_production 
    username: root 
    password: pass 
    host: 127.0.0.1 
    socket: /tmp/mysql.sock 

Answer 2

Install Mysql如果你沒有安裝它。

1. 下載MySQL-connector（zip文件） - 下載noinstall版本（不適用於安裝）。你應該從c:\mysql-connector-c-your-version-download提取到c:\mysql-connector-c-your-version-download

2. 副本libmysql.dll到C:\RailsInstaller\Ruby1.9.3\bin

3. 安裝MySQL寶石

   gem install mysql --platform=ruby -- --with-mysql-dir=C:/mysql-connector-c-your-version-download
