linux误卸载openssl后的恢复

一、原因

由于在编译mysql时，报ssl错误，于是想卸载openssl再重新安装

rpm -qa|grep openssl
rpm -e openssl-1.0.2k-.el7_6..x86_64
rpm -e openssl-1.0.2k-.el7_6..x86_64 --nodeps
rpm -e openssl-libs-1.0.2k-.el7_6..x86_64 --nodeps
rpm -e openssl-devel-1.0.2k-.el7_6..x86_64 --nodeps

二、报错

此时再执行yum报错

[root@server- 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.: 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. (default, Oct  , ::)
[GCC 4.8.  (Red Hat 4.8.-)]

If you cannot solve this problem yourself, please go to
the yum faq at:
  http://yum.baseurl.org/wiki/Faq
  

系统找不到ssl库，所以不能使用命令，不能yum只能rpm本地安装

三、 下载openssl-libs-1.0.2k-12.el7.x86_64.rpm包

下载地址：http://rpmfind.net/linux/centos/7.6.1810/updates/x86_64/Packages/openssl-libs-1.0.2k-16.el7_6.1.x86_64.rpm

先下载到本地电脑，通过rz上传到服务器

四、安装

[root@server- src]# rpm -ivh openssl-libs-1.0.2k-.el7_6..x86_64.rpm
准备中...                          ################################# [%]
        软件包 openssl-libs-:1.0.2k-.el7_6..x86_64 已经安装

五、再执行yum openssl

[root@server- src]# yum search openssl
