安装openssl和openssl-devel

以下借鉴了他人的安装方法，并根据我自己的安装进行了修改

1.下载

wget https://www.openssl.org/source/openssl-1.0.2h.tar.gz
2.解压

tar zxf openssl-1.0.2h.tar.gz

3.安装

cd openssl-1.0.2h

./config shared zlib

because of configuration changes, you MUST do the following before

*** building:

提醒需要在build之前做make depend

make depend

4.

make

make install

 

　mv /usr/bin/openssl /usr/bin/openssl.bak

 

　mv /usr/include/openssl /usr/include/openssl.bak

 

　ln -s /usr/local/ssl/bin/openssl /usr/bin/openssl

 

　ln -s /usr/local/ssl/include/openssl /usr/include/openssl

 

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

 

　ldconfig -v

4.检测安装是否成功

openssl version -a
