You can change your passphrase at any time,using this program with the option "--edit-key".We need to generate a lot of random bytes. It is a good idea to performsome other action (type on the keyboard, move the mouse, utilize thedisks) during the prime generation; this gives the random numbergenerator a better chance to gain enough entropy..+++++.+++++++++++++++.+++++..+++++++++++++++++++++++++..+++++..+++++.++++++++++++++++++++.++++++++++++++++++++++++++++++..++++++++++++++++++++>.++++++++++..........................................+++++Not enough random bytes available.

解决方法：

1.原有进程不退出

2.对一个稍大的tar.gz包解压

[root@clovemzone ~]# tar zxvf mysql-5.5.29.tar.gz

会发现执行完成，稍等片刻的时间，上面的进程会继续下去了

至此问题解决,问题解决的关键就在于这个进程需要更多的随机数什么的，那就给系统点随机字符即可。
