1.系统缺少依赖包
解决方法:
2.安装界面是乱码
解决方法:
测试:
3.ssh服务没有相互信任出现的问题
解决方法:
RAC1中的SSH服务互相信任
[root@rac1 ~]# ssh-keygen -t rsa --在rac1中生成密钥 Generating public/private rsa key pair. Enter file in which to save the key (/root/.ssh/id_rsa): Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /root/.ssh/id_rsa. Your public key has been saved in /root/.ssh/id_rsa.pub. The key fingerprint is: b4:d1:db:49:d4:27:2c:f9:6d:85:cd:cf:e8:2b:53:72 root@rac1 The key‘s randomart image is: +--[ RSA 2048]----+ | .+ + | | . .o = =| | o . .o *o| | . o + .o =| | S . o. . | | .

RAC2中的SSH服务互相信任
[root@rac2 Packages]# ssh-keygen -t rsa Generating public/private rsa key pair.

还有就是ssh和rsh服务都是要互相信任
