4. libcrypto.so.10(libcrypto.so.10)(64bit) is needed by mysql-community-libs-8.0.17-1.el6.x86_64

[root@localhost mysql]# rpm -ivh mysql-community-libs-8.0.17-1.el6.x86_64.rpm 
warning: mysql-community-libs-8.0.17-1.el6.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY

        libssl.so.10(libssl.so.10)(64bit) is needed by mysql-community-libs-8.0.17-1.el6.x86_64

这里用的是 中标麒麟6.4 ，从网上搜索了libcrypto.so.10的rpm包：

http://rpmfind.net/linux/rpm2html/search.php?query=libcrypto.so.10&submit=Search+...&system=&arch=

① 下载了centos el6 版本的 “openssl-1.0.1e-57.el6.i686.rpm” ；

② 使用“ rpm -ivh openssl-1.0.1e-57.el6.x86_64.rpm” 提示与服务器已有的 openssl-1.0.0-27.el6.ns6.01.x86_64 重复了；

③ 使用命令 “ rpm -ivh openssl-1.0.1e-57.el6.x86_64.rpm --force” 强制安装；

④ 重新执行安装 “rpm -ivh mysql-community-libs-8.0.17-1.el6.x86_64.rpm” ，这一次可以安装成功了；
