linux如何写一个脚本完成对a,b,c...多个机器作日常检查

[tabno]

假设有a,b,c...等多个机器，root密码为xxx
已知这些机器都启动了ssh服务，且ssh服务端口号更改为了7050
日常检查包括执行如下命令
echo "press Enter to check error and fail"
echo "------------------------------------"
read
cat /var/log/messages | grep error | more
grep fail /var/log/messages | more
echo "press Enter to check File system"
echo "------------------------------------"
read
df -m
echo "press Enter to check Performance"
echo "------------------------------------"
read
top
echo "press Enter to check cpu and memmory"
echo "------------------------------------"
read
vmstat 1 20

谢谢。

你这不是写好脚本了？

while read ip
do
echo $ip ----------------------------------------------------------------------->>check.log
ssh $name <<EOF>>check.log
root
XXXX
echo "press Enter to check error and fail"
echo "------------------------------------"
read
cat /var/log/messages | grep error | more
grep fail /var/log/messages | more
echo "press Enter to check File system"
echo "------------------------------------"
read
df -m
echo "press Enter to check Performance"
echo "------------------------------------"
read
top
echo "press Enter to check cpu and memmory"
echo "------------------------------------"
read
vmstat 1 20
quit
EOF

done <ip.txt

把要简称的ip地址按行都放在ip.txt内.

ip.txt内容如下:
x4100.unix-center.net
link 1
x4100.unix-center.net
link 2
x4100.unix-center.net
link 3
x4100.unix-center.net
link 4
check.sh内容如下:
#!/bin/bash
while read ip
do
if[ "$ip" = "link*" ]; then
echo $ip
else
ssh $ip<<EOF
TabNo
xxxxx
echo $pwd
fi
done < ip.txt
在x4100.unix-center.net上试的
结果报错:
check.sh: syntax error at line 5: `then' unexpected
