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

执行make && make install报错
Cannot create directory /usr/local/openssl1.1.1: Permission denied
make: *** [Makefile:436：install_runtime_libs] 错误 2

2 解决

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

报错：Can’t locate File/Copy.pm in @INC (you may need to install the File::Copy module) (@INC contains: /usr/local/lib64/perl5/5.32 /usr/local/share/perl5/5.32 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5) at ./util/process_docs.pl line 14.

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。
