检查当前版本

openssl version

下载最新的openssl【2017-11-2】

# apt-get remove openssl【这样卸载会出现很多问题........】

安装

#tar -zxvf openssl-1.1.0g.tar.gz

#cd openssl-1.1.0g/

#./config

#make

#make install

配置

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

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

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

# echo "/usr/local/lib" >> /etc/ld.so.conf

测试：

# openssl version

openssl: error while loading shared libraries: libssl.so.1.1: cannot open shared object file: No such file or directory

openssl: error while loading shared libraries: libcrypto.so.1.1: cannot open shared object file: No such file or directory

# cp /usr/local/lib/libssl.so.1.1 /usr/lib/

# cp /usr/local/lib/libcrypto.so.1.1 /usr/lib/
