openssl升级或降级
一、首先下载源码包
/source/old/
然后选择自己需要的版本
二、解压软件
tar -zxf openssl-1.0.(我这里是1.0.2k版本)
cd openssl-1.0.2k
三、然后安装到安装到/usr/local/openssl/目录下
cd openssl-1.0.2k
./config --prefix=/usr/local/ssl 或./config --prefix=/usr/local/ssl --shared
make && make install
四、备份旧的openssl,然后为新的openssl版本做软连接
mv /usr/bin/openssl /usr/bin/
mv /usr/include/openssl /usr/include/
mv /usr/lib64/openssl /usr/lib64/
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/
#添加so库的路径,添加完成之后,运行ldconfig ,将新增的so 文件缓存到/etc/中;
ldconfig -v
openssl version -a #确认版本是否为1.0.2d
回退:
mv /usr/bin/openssl /usr/bin/
mv /usr/bin/ /usr/bin/openssl
mv /usr/lib64/ /usr/lib64/openssl
ldconfig -v
openssl version查看版本
报错:
[root@localhost include]# openssl version
openssl: error while loading shared libraries: .1.1: cannot open shared object file: No such file or directory
解决;
ln -s /usr/local/ssl/lib/.1.1 /usr/lib64/.1.1
ln -s /usr/local/ssl/lib/.1.1 /usr/lib64/.1.1
