google搜索了一下，有许多朋友遇到过了，有些朋友建议使用低版本的MYSQL进行编译，或者使用centos6.X的操作系统，centos6的操作系统编译MYSQL的时候确实没有遇到过这个个错误。
解决办法：
这其实是MYSQL的一个bug，官方已经发布了补丁，补丁打好之后再编译就可以过去了，具体页面请查看：http://bugs.mysql.com/bug.php?id=68999

Thank you for the report.

Bug #69080 mysql-5.5.31 not compatible with openssl-1.0.0 and lower
was marked as a duplicate.[8 Jun 0:07] Noel Butler
5.5.32 also suffers same fate, i'm amazed oracle had ignored this and the simple included patch that fixes this.
[13 Jun 10:40] Georgi Kodinov
This openssl version is rather old. openssl recommends that you should consider upgrading to a later one.
Is there any obstacle with you upgrading to a recent version ?
Alternatively you can just download the binaries from http://dev.mysql.com/downloads.
[13 Jun 10:44] Remi Collet
> Is there any obstacle with you upgrading to a recent version ?
Enterprise Linux distribution provides backport for security fix.
I don't think upgrade to a more recent version is even thinkable on RHEL, Oracle Linux or other clones.
[13 Jun 10:57] Georgi Kodinov
It's a bit unfortunate that there's no compile time way to check for the presence of that fix.
Thanks for the explanations. It's a valid bug and needs to be fixed.
[28 Jun 14:39] Georgi Kodinov
I would really love if you can provide a way for us to recognize at compile time that this particular openssl version has been patched to include the fix (so I can safely #ifdef the fix that we did on our side).
Any chance that you would consider adding a define specific to your backport of the fix in this version that we can use ?
E.g. adding something like this :
#define OPENSSL_RHEL_COMPRESSION_FIX 1
to openssl.h would work great.
[29 Jun 14:04] Remi Collet
@Georgi Kodinov sorry, I really don't understand the need.
Feel free to open a request for change on RHEL, but...
Why do you think you need this and don't simply #ifdef SSL_OP_NO_COMPRESSION
[29 Jun 15:33] Hartmut Holzgraefe
I don't understand why this can't be fixed by a simple #ifdef (as in the originally attached patch) either ...
[1 Jul 11:51] Georgi Kodinov
Remi,
IMHO we need to be able to distinguish between an un-patched openssl 0.9.8e (that doesn't contain the fixes that you've backported to it) and your patched variant of the same library.
Otherwise there will not be enough information to determine whether to do the fix for this ssl bug in the mysql code or not.[29 Aug 14:21] Georgi Kodinov
