测试ruby和mysql的链接

编写一个简单的脚本来测试链接, 如果显示mysql版本就ok了.

#gvim test.rb

# test.rb - test MySQL script using Ruby DBI modulerequire "dbi"begin    # connect to the MySQL server    dbh = DBI.connect("dbi:Mysql:mysql:localhost", "root", "")    # get server version string and display it    row = dbh.select_one("SELECT VERSION()")    puts "Server version: " + row[0]rescue DBI::DatabaseError => e    puts "An error occurred"    puts "Error code: #{e.err}"    puts "Error message: #{e.errstr}"ensure    # disconnect from server    dbh.disconnect if dbhend

root@debian:/home/ruby# ruby ./test.rb Server version: 5.5.37-0+wheezy1-log</span></span>

测试 rails

#cd /home/www 先进入apache, nginx的www目录, 我这里都设置的一个.

#rails new_project 来建立一个rails的project.

#cd new_project

#rm -rf public/index.html 这里删除掉默认页面,以免一直跳转到这里.

#vim config/database.yml 修改development开发模式的database: ruby_test

#mysql -uroot -p 进入mysql后建一个ruby_test的DB
