centos系统通过源码安装openssl时执行“./config --prefix=/usr/local/openssl1.1.1”报错：

这个错误提示告诉我们当前用户没有权限在/usr/local目录下创建openssl1.1.1目录。在执行make install时，可以添加prefix参数，将openssl安装到可读写的目录下。比如安装到当前用户的主目录下的openssl-1.1.1目录，命令如下：
./config --prefix=/home/用户名/openssl-1.1.1
make && make install

2 解决
这个错误提示告诉我们当前系统的Perl里面没有File::Copy模块。可以通过以下命令安装File::Copy模块：
sudo yum install perl-File-Copy -y
安装完成后，重新执行make命令即可。
