shell批量多台服务器数据copy
[*] 实验服务器两台:
192.168.77.189
192.168.77.190
[*] 服务器免密钥登录设置：
# 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> Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
95:cf:19:a5:ff:d0:bc:80:f5:de:5a:4c:b5:63:ae:c6 root@192_168_77_189
The key's randomart image is:
+--[ RSA 2048]----+

# ssh-copy-id -i /root/.ssh/id_rsa.pub 192.168.77.190
root@192.168.77.190's password:
Now try logging into the machine, with "ssh '192.168.77.190'", and check in:
.ssh/authorized_keys
to make sure we haven't added extra keys that you weren't expecting.
# ssh 192.168.77.190

# exit
[*] copy脚本
#!/bin/bash
#write by lixi
#time by 2015-7-7
#run by sh auto.shell.sh /root /mnt
if [ ! -f ip.txt ] ; then
echo -e "\033[32mplease create ip.txt files...\033[0m"
catip.txt.swp
IP=`awk -v I="$i" '{if(I==$1)print $2}' ip.txt.swp`
scp -r $1 root@${IP}:$2
#rsync -ap --delete $1 root@${IP}:$2
done
以上脚本用rsync也可以，，，rsync同步两个文件一样，，，例如sh auto.shell.sh /opt/ /opt/保持两个服务器之间这个目录文件一样
4.批量远程服务器执行命令
#!/bin/bash
# Auto run server commend
# by lx 2015-7-7
if [ ! -f ip.txt ]; then
echo -e "\033[32mplease create ip.txt files...\033[0m"
cat ip.txt.swp
IP=`awk -v I="$i" '{if(I==$1)print $2}' ip.txt.swp`
ssh -q -l root $IP "$*; echo -e '-----------------------\nthe $IP Exec command:
$* success !';sleep 2"
done
root@192_168_77_189 ~]# sh auto_ssh.sh mkdir /tmp/text2
-----------------------
the 192.168.77.190 Exec command:
mkdir /tmp/text2 success !
-----------------------
the 192.168.77.189 Exec command:
mkdir /tmp/text2 success !
5.服务器之前文件同步：
#!/bin/bash
#by lixi 2015.7.7
#run by sh auto_rsync.sh flush
flush()
{
if
[ ! -f rsync.list ]; then
echo -e "\033[32mplease create rsync.list file...\033[0m"
cat rsync.list.swp
COUNT=`cat rsync.list.swp|wc -l`
NUM=0
while ((${NUM} < $COUNT))
do
NUM=`expr $NUM + 1`
Line=`sed -n "${NUM}p" rsync.list.swp`
SRC=`echo $Line |awk '{print $2}'`
DES=`echo $Line |awk '{print $3}'`
IP=`echo $Line |awk '{print $1}'`
rsync -ap --delete ${SRC}/ root@${IP}:${DES}/
done
}
restart()
{
rm -rf restart.list.swp ; cat restart.list | grep -v "#" >> restart.list.swp
COUNT=`cat restart.list.swp|wc -l`
NUM=0
while ((${NUM} < $COUNT))
do
NUM=`expr $NUM + 1`
Line=`sed -n "${NUM}p" restart.list.swp`
Command=`echo $Line |awk '{print $2}'`
IP=`echo $Line |awk '{print $1}'`
ssh -l root $IP "sh $Command; echo -e '----------------\nthe $IP Exec Commadn : sh $Command success !'"
done
