Both Hadoop and ansible need this stuff, which is really simple.First, generate the public and private keys on the machine that requires a secret-free login:Ssh-keygenSecond, the copy-generated public key is id_rsa.pub to the remote machine:Ssh-copy-id-i/root/.ssh/id_rsa.pub [email protected] #用此方式拷贝的好处是不用改名Then login to the 192.168.0.247 machine will not need a password.[Email protected]_server ~]# ssh 192.168.0.247Last login:mon Nov 13:48:33 from 192.168.0.3[[email protected] ~]#If you are a r

Problem Description:　　My arch Linux has been used for more than half a year, because of the rolling problems of Arch Linux, I have never directly upgraded the system. Software versions and libraries are naturally lagging behind.When I was ready to use NFS, the network file system was mounted because the LIBRPC was too old to fail. So I guess I'll have to update librpc. Look at the version on the source with

Configure two-way password-free authentication for SSH in LinuxI. Implementation Principle Use a public/private key authentication method for ssh login. The following is a simple explanation of the "Public/Private Key" authentication method:First, create a pair of public and private keys on the client (Public Key File :~ /. Ssh/id_rsa.pub; private key file :~ /.
