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-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 302018, 23:45:53)
[GCC 4.8.520150623 (Red Hat 4.8.5-36)]
If you cannot solve this problem yourself, please go to
the yum faq at:
/wiki/Faq
系统不到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
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
