通过expect自动登录到30台linux机器运行相同命令
一、用以下expect脚本可以同时对200台机器执行同一个命令，
比如：打补丁(expect remote.exp)
#!/user/bin/expect -f
for {set i 1} {$i<=200} {incr i} {
spawn ssh -p 1022 -l root 192.168.6.$i
expect "*password: "
sleep 3
send "123456\r"
expect "username\r"
send "su -\r" #SSH普通用户名密码登录
expect "Password:"
send "123456\r" #SSH的root用户名密码登录
expect -timeout 1
expect "root"
#send "find / -name sambafeng.txt\r"
send "patch -R -p1 patching file prj0name\r"
#interact 中断调试
}
二、用ssh密钥方式
#!/bin/bash
#============author sambafeng===================
#==============INIT=============================
deployDir=/opt/fordeploy
backup=/opt/backup
scriptDir=/opt/script
#=============IP Partten=================================================
#url="$1"
#url_1=${url//\\//}
#url_2=${url_1#*94}
#dir="/opt/share"$url_2
#appname=$(ls -l ${dir}/|grep "\."|awk '{printf $9 "\n"}')
#cp $dir/$appname $deployDir
#=============eli the version====================
x=0
for filename in $deployDir/*;
do
fullname=$(basename $filename)
p_name=$(echo $fullname|awk -F "-[0-9]" '{print $1}'|awk -F "-stage2" '{print $1}'|awk -F "." '{print $1}')
p_type=$(echo $fullname| rev | cut -c 1-3 | rev)
PackageName="$p_name"."$p_type"
mv -f $deployDir/$fullname $deployDir/$PackageName
array[$x]=$PackageName
let x+=1
done
#===============Remote deploy===================================================
echo "please select the package for deploy"
select var in ${array[@]}
do
for n in $(cat /opt/script/map.properties |grep "${var}")
do
list=($(echo $n | awk -F',' '{printf("%s %s %s %s",$1,$2,$3,$4)}'))
echo "==PackageName:${list[0]}==serverIp:${list[1]}==NodeName:${list[2]}==appName:${list[3]}========"
echo -n "Are sure begin deploy?(Y/N)"
read YES_OR_NO
case $YES_OR_NO in
y|Y|yes|YES)
scp $deployDir/${list[0]} oracle@${list[1]}:$deployDir
ssh ${list[1]} "sh $scriptDir/redeploy.sh ${list[2]} ${list[3]} ${list[0]};exit;"
;;
n|N|no|NO)
echo "canceled"
;;
*)
echo "Error ,you should input[Y|N]"
exit 1
;;
esac
done
rm -f $deployDir/${list[0]}
echo "$var deploy finished"
done
三、python实现ssh批量登陆执行命令 #!/usr/bin/env python import pexpect def ssh_cmd(ip, passwd, cmd): ret = -1 ssh = pexpect.spawn('ssh root@%s "%s"' % (ip, cmd)) try: i = ssh.expect(['password:', 'continue connecting (yes/no)?'], timeout=5) if i == 0 : ssh.sendline(passwd) elif i == 1: ssh.sendline('yes\n') ssh.expect('password: ') ssh.sendline(passwd) ssh.sendline(cmd) r = ssh.read() print r ret = 0 except pexpect.EOF: print "EOF" ssh.close() ret = -1 except pexpect.TIMEOUT: print "TIMEOUT" ssh.close() ret = -2 return ret #!/usr/bin/python import paramiko import threading def ssh2(ip,username,passwd,cmd): try: ssh = paramiko.SSHClient() ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) ssh.connect(ip,22,username,passwd,timeout=5) for m in cmd: stdin, stdout, stderr = ssh.exec_command(m) # stdin.write("Y") #简单交互，输入 ‘Y’ out = stdout.readlines() #屏幕输出 for o in out: print o, print '%s\tOK\n'%(ip) ssh.close() except : print '%s\tError\n'%(ip) if __name__=='__main__': cmd = ['cal','echo hello!']#你要执行的命令列表 username = "" #用户名 passwd = "" #密码 threads = [] #多线程 print "Begin......" for i in range(1,254): ip = '192.168.1.'+str(i) a=threading.Thread(target=ssh2,args=(ip,username,passwd,cmd)) a.start()
