1、当前系统版本号

 -sh-4.1$ cat /etc/redhat-release
 CentOS release 6.5 (Final)
 -sh-4.1$ uname -m
 x86_64
 -sh-4.1$ uname -r
 2.6.32-431.17.1.el6.x86_64

2、SSL版本号信息

 # openssl version
 OpenSSL 1.0.1e-fips 11 Feb 2013
 # wget https://www.openssl.org/source/openssl-1.0.1g.tar.gz
 …………    ### 具体信息

3、更新zlib

 

 # yum install -y zlib

4、解压安装 OpenSSL

 # pwd
 /root/tools
 # ls
 openssl-1.0.1g.tar.gz
 # tar xf openssl-1.0.1g.tar.gz
 # cd openssl-1.0.1g
 # ./config shared zlib
 # make
 # make install
 # cd ..
 # mv /usr/bin/openssl /usr/bin/openssl.ori              # 将之前的备份
 # mv /usr/include/openssl /usr/include/openssl.ori
 # ln -s /usr/local/ssl/bin/openssl /usr/bin/openssl     # 软链接
 # ln -s /usr/local/ssl/include/openssl /usr/include/openssl
 # cp /etc/ld.so.conf /etc/ld.so.conf.ori                # 操作前备份【这样假设出现错误，能够及时还原】
 # echo “/usr/local/ssl/lib” >> /etc/ld.so.conf
 # ldconfig -v

当中 /etc/ld.so.conf 改动后的信息【使用vim改动】

 [zhang@zhang ~] $ cat /etc/ld.so.conf
 include ld.so.conf.d/*.conf

 #  Update openssl from OpenSSL 1.0.1e-fips  To   OpenSSL 1.0.1g
 /usr/local/ssl/lib

5、查看是否升级成功

 

 # openssl version
 OpenSSL 1.0.1g 7 Apr 2014       # 升级成功
