Please select what kind of key you want:

(1) DSA and Elgamal (default)

(2) DSA (sign only)

(5) RSA (sign only)

Your selection? 1

DSA keypair will have 1024 bits.

ELG-E keys may be between 1024 and 4096 bits long.

What keysize do you want? (2048)

Requested keysize is 2048 bits

Please specify how long the key should be valid.

0 = key does not expire

= key expires in n days

w = key expires in n weeks

m = key expires in n months

y = key expires in n years

Key is valid for? (0) 0

Key does not expire at all

Is this correct? (y/N) y

You need a user ID to identify your key; the software constructs the user ID

from the Real Name, Comment and Email Address in this form:

"Heinrich Heine (Der Dichter) "

Real name: clovemzone

Email address: clovem@gmail.com

Comment: clovem key

You selected this USER-ID:

"clovemzone (fdfd) "

Change (N)ame, (C)omment, (E)mail or (O)kay/(Q)uit? O

You need a Passphrase to protect your secret key.

You don't want a passphrase - this is probably a *bad* idea!

I will do it anyway. 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 perform

some other action (type on the keyboard, move the mouse, utilize the

disks) during the prime generation; this gives the random number

generator a better chance to gain enough entropy.

Not enough random bytes available. Please do some other work to give

the OS a chance to collect more entropy! (Need 274 more bytes)

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。
