本来第二部分是想测试主服务器挂掉，提升从服务器的情况，可是出了点点意外，改为测试某一台从服务器挂掉的时候，如何恢复。
主服务器挂掉的情况放到第三部分吧。
继续用mysql::sandbox来测试。
主服务器(别名black)(server-id:1)安装在 /home/modify/sandboxes/msb_5_6_10/ 使用5610端口。
从服务器(别名blue)(server-id:2)安装在 /home/modify/sandboxes/msb_5_6_10_a/ 使用5611端口。
从服务器(别名green)(server-id:3)安装在 /home/modify/sandboxes/msb_5_6_10_b/ 使用5612端口。
按照前一篇文章介绍的方法设置好一主二从的复制。
