在最后一行我们看到删除了 systemd 和 yum

Error: Trying to remove "systemd", which is protected
Error: Trying to remove "yum", which is protected

我们如何强制 yum remove 以删除 openssl-libs rpm？

Answer 1

我正式建议您不要删除随操作系统核心提供的 openssl 版本，因为您会看到您的包管理器“yum”和“systemd”主要依赖于它，因此这会破坏它。相反，我建议：

• 升级系统至RHEL6使用 好吃

或者

• 安装新的openssl独立于操作系统的包，那么您的系统包和应用程序将基于此特色：

  mkdir ~/src/

  cd ~/src/

  wget https://www.openssl.org/source/openssl-1.0.2a.tar.gz

  tar -zxvf openssl-*.tar.gz

  cd openssl-*

  ./config -fpic shared && make && make install

  echo "/usr/local/ssl/lib" >> /etc/ld.so.conf

  ldconfig

现在检查你的 openssl 版本：

openssl version
