测试环境Centos7 openssl升降级操作

• 升级

Openssl version #查询当前版本为1.0.1e

Wget https://www.openssl.org/source/openssl-1.1.0k.tar.gz 

Tar zxvf openssl-1.1.0k.tar.gz

Cd openssl-1.1.0k

./config –prefix=/usr/local/openssl

Make && make install

Mv -f /usr/bin/openssl /usr/bin/openssl.bak

Mv -f /usr/include/openssl /usr/include/openssl.bak

Ln -s /usr/local/bin/openssl usr/bin/openssl    #修改软连接  指向新的openssl

Ln -s /usr/local/include/openssl usr/include/openssl

Echo “/usr/local/lib64” >> /etc/ld.so.conf  #添加so库的路径

Ldconfig -v    #将新的so文件缓存到/etc/ld.so.cache

Openssl version -a   #查看版本是否为1.1.0k

• 降级

Cd openssl-1.1.0k

Sudo make uninstall  卸载源码包安装的openssl

Yum remove openssl    #必须要 不然安装完成查询版本会报错

Yum install openssl openssl-devel -y

Openssl version -a 查看版本是否回退到1.0.1e
