[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.

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.

[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
