配置集群用户以及配置集群节点间无密码ssh登陆

#-----------createanewuserwhichusernameis'zhangliuhang'andpasswordis'111111'-----------
#cmd='useraddzhangliuhang;echo'111111'|passwdzhangliuhang--stdin'

#for((i=1;i<=4;i++))do
#for((j=1;j<=8;j++))do
#sshpass-p111111sshroot@gd1$i$j$cmd

剩下的脚本应该在zhangliuhang用户下进行

#---------testasuserzhangliuhangnotroot-------------------------------------------------
#for((i=1;i<=4;i++))do
#for((j=1;j<=8;j++))do
#sshgd1$i$jhostname

#done
