linux主机ssh信任配置

主机之间的ssh信任，简单地说就是主机之间使用ssh命令登陆主机不需要密码。

1、2台主机之间配置ssh信任机制：

server152-153
server152:
ssh-keygen -t rsa
cd /root/.ssh
cat id_rsa.pub >> authorized_keys
chmod 600 authorized_keys
scp -r /root/.ssh  root@192.168.195.153:/root
 


server153:
ssh-keygen -t rsa
cd /root/.ssh
cat id_rsa.pub >> authorized_keys
chmod 600 authorized_keys
scp authorized_keys root@192.168.195.152:/root/.ssh/authorized_keys

2、多台主机之间配置ssh信任机制：
server152-153-154-155
server152:
ssh-keygen -t rsa
cd /root/.ssh
cat id_rsa.pub >> authorized_keys
chmod 600 authorized_keys
scp -r /root/.ssh  root@192.168.195.153:/root
 


server153:
ssh-keygen -t rsa
cd /root/.ssh
cat id_rsa.pub >> authorized_keys
chmod 600 authorized_keys
scp -r /root/.ssh  root@192.168.195.154:/root


server154:
ssh-keygen -t rsa
cd /root/.ssh
cat id_rsa.pub >> authorized_keys
chmod 600 authorized_keys
scp -r /root/.ssh  root@192.168.195.155:/root




server155:
ssh-keygen -t rsa
cd /root/.ssh
cat id_rsa.pub >> authorized_keys
chmod 600 authorized_keys
scp authorized_keys root@192.168.195.152:/root/.ssh/authorized_keys
scp authorized_keys root@192.168.195.153:/root/.ssh/authorized_keys

scp authorized_keys root@192.168.195.154:/root/.ssh/authorized_keys
