debian openssl升级1.0 到 1.1

wget https://www.openssl.org/source/openssl-1.1.1n.tar.gz
tar -zxvf openssl-1.1.1n.tar.gz  #解压
cd openssl-1.1.1n
./config --prefix=/usr/local/openssl   --openssldir=/usr/local/openssl  shared zlib
make
make install

3.备份原来的配置
mv /usr/bin/openssl /usr/bin/openssl.bak
mv /usr/include/openssl  /usr/include/openssl.bak

4.配置新版本的链接
#将安装好的openssl 的openssl命令软连到/usr/bin/openssl
ln -s /usr/local/openssl/include/openssl /usr/include/openssl

#将安装好的openssl命令软连到/usr/bin/openssl
ln -s /usr/local/openssl/bin/openssl /usr/bin/openssl

在/etc/profile里添加环境变量
export LDFLAGS=" -L/usr/local/openssl/lib"
export CPPFLAGS=" -I/usr/local/openssl/include"
export PKG_CONFIG_PATH="/usr/local/openssl/lib/pkgconfig"
