这个问题
我装了 ruby1.8.7
gem是1.3.7
mysql-ruby-2.8.2.tar
rails是gem自动安装的

最后运行rails server时候，就出现这个

/usr/local/ruby/lib/ruby/gems/1.8/gems/mysql2-0.2.6/lib/mysql2/这个路径下，有没看到mysql2.so？把mysql2.so放到这来。

有的

[root@localhost mysql2]# pwd
/usr/local/ruby/lib/ruby/gems/1.8/gems/mysql2-0.2.6/lib/mysql2
[root@localhost mysql2]# ls mysql2.so
mysql2.so
[root@localhost mysql2]#

呃，不知道Rails里你是怎么配MySQL的。就是提示：No such file or directory哦？

瓜哥哥，我能启动了，将libmysqlclient.so.16放在了/usr/local/ruby/lib下了
不过，我还没建什么表，首页就很慢很慢啊，我用的虚拟机，512内存，用rails自带的服务器，好几秒才出来，为什么呢

虚拟机当然慢了，况且才512内存。

我也查看了rails的版本，是3.0.3的，好高啊

$ ldd /usr/lib/ruby/1.8/x86_64-linux/mysql.so | grep libmysqlclient
libmysqlclient.so.16 => /usr/lib/libmysqlclient.so.16 (0x00007faaad30d000)
$ dpkg -S /usr/lib/libmysqlclient.so.16
libmysqlclient16: /usr/lib/libmysqlclient.so.16

复制代码

把这个包装上：libmysqlclient16

还要装libmysqlclient-dev的。
