centos 5.x 升级openssl

    今日想在centos 5.2上面安装mysql 5.5.37,在make的时候提示: 

Linking C shared module adt_null.so

百度得知是mysql5.5无法在openssl-1.0.0及更低版本下编译导致的。如果不需要ssl可以去掉WITH_SSL配置项，也可以升级openssl的版本，当然还有个更方便的办法:

以在cmake之前打一个补丁。

#下载补丁 并安装 因centos所在机器不能上网,故未测试
wget -c "http://bugs.mysql.com/file.php?id=19941&bug_id=68999" -O mysql-openssl.patch

patch -p1   mysql-openssl.patch

我采用升级openssl的方式

1.下载openssl 1.01 略.

2. 解压并安装openssl

tar vxf openssl-1.0.1g.tar.gz

cd openssl-1.0.1g

./config shared zlip

   make && make install

   mv /usr/bin/openssl /usr/bin/openssl.OFF

   mv /usr/include/openssl /usr/include/openssl.OFF
   ln -s /usr/local/ssl/bin/openssl /usr/bin/openssl
   ln -s /usr/local/ssl/include/openssl /usr/include/openssl 

  #配置搜索文件路径
   echo "/usr/local/ssl/lib" >> /etc/ld.so.conf

   ldconfig -v
    #查看当前版本

root@localhost tools]# openssl version -a
OpenSSL 1.0.1g 7 Apr 2014

 至此升级OK了~
