2. Experiment Server Two:

   192.168.77.190

3. Server-free key login settings:

   [email protected]_168_77_189 ~]# Ssh-keygen
   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:

   Now try logging to the machine, with "ssh ' 192.168.77.190 '", and check in:

   To make sure we haven ' t added extra keys so you weren ' t expecting.

   [[Email protected]_168_77_189 ~]# ssh 192.168.77.190

5. Copy Script

#!/bin/bash#write by lixi#time by 2015-7-7  #run  by sh auto.shell.sh  /root /mntif    [ ! -f ip.txt ] ; thenecho - e  "\033[32mplease create ip.txt files...\033[0m" cat <<  eof192.168.149.128192.168.149.129eof        exitfiif  [  -z  "$"  ] ; then        echo -e  "\ 033[32musage $0 command,example{src_file|src_dir des_dir\033[0m} "         exitficount= ' Cat ip.txt | wc -l ' rm -rf ip.txt.swpi=0while    (i< $count) doi= ' expr  $i  + 1 ' sed  "${i}s/^/&${i} /g"    ip.txt >> ip.txt.swpip= ' awk -v i= ' $i   ' {if (i==$1) print $2} '   Ip.txt.swp ' Scp -r $1 [email protecTed]${ip}:$2#rsync -ap --delete $1 [email protected]${ip}:$2done 

The above script with rsync can also,,, rsync sync two files like,,, such as SH auto.shell.sh/opt//opt/keep two servers between this directory file like

4. Batch remote server execution commands

#!/bin/bash# auto run server commend# by lx 2015-7-7if [ ! - f ip.txt ]; then        echo -e  "\033[ 32mplease create ip.txt files...\033[0m "cat <<  eof192.168.149.128192.168.149.129eof        exitfiif          [ -z  "$*"  ] ; then         echo -e  "\033[32musage: $0 commend,example{rm /tmp/text.txt|mkdir  /tmp/text2}\033[0m "        exitfi         count= ' Cat ip.txt | wc -l '          rm -rf ip.txt.swp        i=0while  ((i< $count)) Do        i= ' Expr  $i  + 1 '         sed  "${i}s/^/&${i} /g"  ip.txt >>ip.txt.swp        ip= ' awk -v I= ' $i "  ' {if (i==$1) print $2} '  ip.txt.swp ' ssh -q -l root  $IP  " $*; echo  -e  '-----------------------\nthe  $IP  exec command:$* success ! '; Sleep 2 "Done

[Email protected]_168_77_189 ~]# sh auto_ssh.sh mkdir/tmp/text2-----------------------the 192.168.77.190 Exec command: MKDIR/TMP/TEXT2 Success!-----------------------the 192.168.77.189 Exec command:mkdir/tmp/text2 success!

#run by SH auto_rsync.sh flush
