linux误卸载openssl后的恢复教程
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-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、报错
此时再执行yum报错
[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-1 src]# rpm -ivh openssl-libs-1.0.2k-16.el7_6.1.x86_64.rpm
准备中... ################################# [100%]
软件包 openssl-libs-1:1.0.2k-16.el7_6.1.x86_64 已经安装五、再执行yum openssl
[root@server-1 src]# yum search openssl
