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 module require "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 dbh end
<span style="background-color: rgb(102, 102, 102);"><span style="color:#ffffff;">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DBroot@debian:/home/www# mysql -u root -p Enter password: Welcome to the MySQL monitor.
