一、原因
由於在編譯mysql時，報ssl錯誤，於是想卸載openssl再重新安裝
rpm -qa|grep openssl rpm -e openssl-1.0.2k-16.el7_6.1.x86_64 rpm -e openssl-1.0.2k-16.el7_6.1.x86_64 --nodeps rpm -e openssl-libs-1.0.2k-16.el7_6.1.x86_64 --nodeps rpm -e openssl-devel-1.0.2k-16.el7_6.1.x86_64 --nodeps
二、報錯
此時再執行yum報錯
[root@server-1 lib64]# yum install openssl There was a problem importing one of the Python modules required to run yum. The error leading to this problem was: libcrypto.so.10: cannot open shared object file: No such file or directory Please install a package which provides this module, or verify that the module is installed correctly. It's possible that the above module doesn't match the current version of Python, which is: 2.7.5 (default, Oct 30 2018, 23:45:53) [GCC 4.8.5 20150623 (Red Hat 4.8.5-36)] If you cannot solve this problem yourself, please go to the yum faq at: http://yum.baseurl.org/wiki/Faq
系統找不到ssl庫，所以不能使用命令，不能yum只能rpm本地安裝
三、 下載openssl-libs-1.0.2k-12.el7.x86_64.rpm包
下載地址：http://rpmfind.net/linux/centos/7.6.1810/updates/x86_64/Packages/openssl-libs-1.0.2k-16.el7_6.1.x86_64.rpm
先下載到本地電腦，通過rz上傳到服務器
四、安裝
[root@server-1 src]# rpm -ivh openssl-libs-1.0.2k-16.el7_6.1.x86_64.rpm 准備中... ################################# [100%] 軟件包 openssl-libs-1:1.0.2k-16.el7_6.1.x86_64 已經安裝
五、再執行yum openssl
