centos 编译OpenSSL

1、从下列页面下载最新的OpenSSL http://openssl.org/source/

2、解压编译

wget -c https://www.openssl.org/source/openssl-1.0.2j.tar.gz 
tar zxvf openssl-1.0.2j.tar.gz 
cd openssl-1.0.2j
./config
make 
make install

2、执行以下命令：

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

3 配置库文件搜索路径

#echo “/usr/local/ssl/lib” >> /etc/ld.so.conf.d/ssl.conf
#ldconfig

4 查看openssl 版本号，验证安装正确性
