[linux] ssh远程执行本地脚本

　　1.ssh密钥登录

略

　　2.免确认机器指纹，ssh -o StrictHostKeyChecking=no

[root@XM-v125 ~]# ssh wykai@192.168.0.110

The authenticity of host '192.168.0.110 (192.168.0.110)' can't be established.

ECDSA key fingerprint is SHA256:vV9qNhRA/1/nDkjI0kUiwQBV86MyvfBjEY3V/7IOYZA.

ECDSA key fingerprint is MD5:37:95:b7:c0:fa:e4:76:63:2d:5e:cb:54:be:85:6e:08.

Are you sure you want to continue connecting (yes/no)? no

Host key verification failed.

[root@XM-v125 ~]# ssh -o StrictHostKeyChecking=no wykai@192.168.0.110

Warning: Permanently added '192.168.0.110' (ECDSA) to the list of known hosts.

Last login: Mon Sep  3 15:23:24 2018 from 192.168.1.180

[wykai@XM-v110 ~]$

　　3.执行本地脚本，< /root/local.sh

[root@XM-v125 ~]# cat /root/local.sh

echo $PATH

hostname

echo $1

ip a show dev eth0

[root@XM-v125 ~]# ssh -o StrictHostKeyChecking=no wykai@192.168.0.110  < /root/local.sh

Pseudo-terminal will not be allocated because stdin is not a terminal.

/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/usr/local/jdk/bin:/home/wykai/.local/bin:/home/wykai/bin

XM-v110

2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000

    link/ether ae:07:76:1d:76:70 brd ff:ff:ff:ff:ff:ff

    inet 192.168.0.110/23 brd 192.168.1.255 scope global eth0

       valid_lft forever preferred_lft forever

    inet6 fe80::ac07:76ff:fe1d:7670/64 scope link

       valid_lft forever preferred_lft forever

[root@XM-v125 ~]#

　　4.脚本加参数，bash -s < /root.local.sh arg1

[root@XM-v125 ~]# ssh -o StrictHostKeyChecking=no wykai@192.168.0.110 < /root/local.sh arg1

bash: arg1: command not found

[root@XM-v125 ~]# ssh -o StrictHostKeyChecking=no wykai@192.168.0.110 bash -s < /root/local.sh arg1

/usr/local/bin:/usr/bin:/usr/local/jdk/bin

XM-v110

arg1

bash: line 4: ip: command not found

[root@XM-v125 ~]#

　　5.以sudo权限执行

[root@XM-v125 ~]# ssh -o StrictHostKeyChecking=no wykai@192.168.0.110 sudo bash -s < /root/local.sh arg1

/sbin:/bin:/usr/sbin:/usr/bin

XM-v110

arg1

2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000

    link/ether ae:07:76:1d:76:70 brd ff:ff:ff:ff:ff:ff

    inet 192.168.0.110/23 brd 192.168.1.255 scope global eth0

       valid_lft forever preferred_lft forever

    inet6 fe80::ac07:76ff:fe1d:7670/64 scope link

       valid_lft forever preferred_lft forever

　　6.特殊符号的脚本参数

[root@XM-v125 ~]# ssh -o StrictHostKeyChecking=no wykai@192.168.0.110 sudo bash -s < /root/local.sh -d

bash: -d: invalid option

/sbin:/bin:/usr/sbin:/usr/bin

XM-v110

-d

2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000

    link/ether ae:07:76:1d:76:70 brd ff:ff:ff:ff:ff:ff

    inet 192.168.0.110/23 brd 192.168.1.255 scope global eth0

       valid_lft forever preferred_lft forever
