安装环境

[root@192 ~]# uname -a
Linux 192.168.11.121 3.10.0-1160.62.1.el7.x86_64 #1 SMP Tue Apr 5 16:57:59 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux

安装包下载

# 下载地址 --- 下载版本: 3.0.1 (openssl-3.0.1.tar.gz)
https://www.openssl.org/source/old/3.0/

解压

tar -zxvf openssl-3.0.1.tar.gz 
cd openssl-3.0.1

配置

# --prefix指定安装路径
./config --prefix=/usr/local/openssl

这里有个问题，会报如下错误：

Cant locate IPC/Cmd.pm in @INC (@INC contains: /root/Downloads/openssl-3.0.1/util/perl /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 . /root/Downloads/openssl-3.0.1/external/perl/Text-Template-1.56/lib) at /root/Downloads/openssl-3.0.1/util/perl/OpenSSL/config.pm line 18.

Compilation failed in require at /root/Downloads/openssl-3.0.1/Configure line 23.
BEGIN failed--compilation aborted at /root/Downloads/openssl-3.0.1/Configure line 23.

解决方法：

1）安装perl-CPAN

yum install -y perl-CPAN

2）进入CPAN的shell模式

perl -MCPAN -e shell

3）安装缺少的模块

cpan[1]> install IPC/Cmd.pm

编译安装

make
make install

# 查看安装结果
[root@192 /usr/local/openssl]# ls
bin  include  lib64  share  ssl
