# 以前用到的一些简单脚本 #

[2019年2月24日][2019_2_24][韩休雨][Link 1][Centos][]

1.拷贝文件

scp.sh

\#!/bin/bash

read -p “将要存放的路径:” save\_path  
read -p “要复制的文件路径:” get\_path  
iplist\_path=/data/iplist.txt  
while read ip ;do  
(\[ -s $get\_path \] && scp $get\_path $ip:$save\_path) || echo ‘file do not exist !’  
done < $iplist\_path

2.第一次输入免秘钥

expect.sh

\#!/bin/bash

mkdir /data  
rpm -q expect || yum -y install expect  
path=/data/iplist.txt  
pass=”123456″  
ssh-keygen -t rsa -P “” -f /root/.ssh/id\_rsa  
while read ip ;do  
expect <<EOF  
spawn ssh-copy-id -i /root/.ssh/id\_rsa.pub $ip  
expect \{  
“yes/no” \{ send “yes\\n”;exp\_continue \}  
“password” \{ send “$pass\\n” \}  
\}  
expect eof  
EOF  
done < $path

3.执行脚本

run.sh

\#!/bin/bash

\#想要在执行完成后删除脚本，可以在想要执行的脚本后面添加”rm -f $0″

rpm -q pssh||yum -y install pssh  
path=/data/iplist.txt  
pscp.pssh -v -h $path “$1” /  
pssh -v -h $path “bash /\*.sh”

3.批量创建账户

path=/data/passwd  
chattr +a $path  
read -p “input the num of beginning : ” j  
read -p “input the num of beginning : ” k  
for i in \`seq $j $k\` ; do  
if \`seq $j $k\` ;then  
echo user$i is exist  
continue  
else  
eval echo user$i|xargs -n 1 useradd &>/dev/null  
eval echo -e user$i:\`openssl rand -base64 12\`”\\n”|tr -s ‘ ‘ “\\n” >> $path  
passwd=\`sed -nr “s/user$i:(.\*)/\\1/p $path\`  
sed -nr “s/.*user$i:(.*)/\\1/p” $path |passwd –stdin user$i  
echo The passwd of user$i is $passwd

done

\#设置密码另一种方式，以前的文章中应该有设置密码的string函数，那个方式是从前领导那学来的  
tr -cd \[\[:alnum:\]!\_\#@\] < /dev/urandom |head -c 8

4.扫描IP，并设置免密登录

read -p “输入想要扫描的范围” field

\#!/bin/bash

grep “id” \`ls /root/.ssh/\`

*if \[ “$0” -eq 0 \];then*

*rm /root/.ssh/id* \-f  
fi  
pass=”1″  
ssh-keygen -t rsa -P “” -f /root/.ssh/id\_rsa  
path=/data/iplist.txt

yum -y install tree expect pssh bash-completion\* lrzsz vim net-tools  
cd /  
if \[ -e ./data \];then  
if \[ -d ./data \];then  
touch iplist.txt;echo 是个目录,创建了iplist.txt文件  
else  
rm -f ./data ;echo 是个文件  
fi  
else  
mkdir ./data && touch /data/iplist.txt;echo 没有这个目录以及文件  
fi

for i in \`seq 254\`;do  
\{  
ping -c1 -w1 $field.$i &>/dev/null  
if \[ “$?” -eq 0 \];then  
grep “$field.$i” $path &>/dev/null  
if \[ “$?” -ne 0 \];then  
while \[ “$i” -le 255 \] ;do  
expect << EOF

spawn ssh-copy-id -i /root/.ssh/id\_rsa.pub $field.$i  
expect \{  
“yes/no” \{ send “yes\\n”;exp\_continue \}  
“password” \{ send “$pass\\n” \}  
\}  
expect eof  
EOF  
if \[ “$?” -eq 0 \];then  
echo $field .$i >> $path  
fi  
let i++  
done  
fi  
fi  
\}&  
done

5.判断文件类型（从宗华老师那学来的）

\#!/bin/bash

read -p “input path (example:/root/\*) ” path  
if \[ ! -e $path \];then  
echo “file don’t exist”&&exit 1  
else  
for i in $path ;do  
if \[ -b $i \];then  
echo “$i:块设备”  
elif \[ -c $i \];then  
echo “$i:符号设备”  
elif \[ -d $i \];then  
echo “$i:目录文件”  
elif \[ -f $i \];then  
echo “$i:普通文件”  
elif \[ -h $i \];then  
echo “$i:链接文件”  
elif \[ -p $i \];then  
echo “$i:管道设备”  
elif \[ -s $i \];then  
echo “$i:套接字文件”  
fi  
done  
fi

6.创建html文件

\#!/bin/bash

path=/data/  
read -p “First :” f  
read -p “Last :” l  
for i in \`seq $f $l\`;do  
touch $path$i\`tr -dc “\[:alnum:\]” </dev/urandom |head -c 8\`.html  
done

6.服务脚本（从宗华老师那学来的）

\#!/bin/sh

\#chkconfig:- 96 07

\#description

name=\`basename $0\`  
\[ -f /etc/rc.d/init.d/$name \]||mv /app/script/$name /etc/rc.d/init.d/$name &>/dev/null  
chkconfig –add $name  
start () \{  
touch /var/lock/subsys/ $name  
. /etc/init.d/functions  
action ” $name start successful!” true  
\}  
stop () \{  
rm /var/lock/subsys/$name  
. /etc/init.d/functions  
action ” $name is stopped” true  
\}  
restart () \{  
stop  
start  
\}  
status () \{  
if \[ -f /var/lock/subsys/$name \];then  
. /etc/init.d/functions  
action “$name is running” true  
else  
action “$name is stopped” true  
fi  
\}  
case $1 in  
start)  
if \[ -f /var/lock/subsys/$name \];then  
echo “$name is running”  
else  
start  
fi  
;;  
stop)  
if \[ -f /var/lock/subsys/$name \];then  
stop  
else  
echo “$name has been stopped before”  
fi  
;;  
restart)  
if \[ -f /var/lock/subsys/$name \];then  
stop  
start  
else  
start  
fi  
;;  
status)  
status  
;;  
esac
