用ssh和互信链接建立批量执行

main server: 192.168.100.101

sub sever1: 192.168.100.102

sub server2: 192.168.100.103

main server执行脚本:/data/release/run.sh

#!/bin/sh
if [ -z "$1" ]; then
  echo "need para!"
  exit
fi
port=
target=/data/release/run.sh
srvs=(192.168.100.102 192.168.100.103)

for srv in ${srvs[*]}
do
        ssh -f -p $port $srv $target \"$1\" &
done

sub server执行脚本：/data/release/run.sh

#!/bin/sh
if [ -z "$1" ]; then
 echo "need para!"
  exit
fi
cd /data/release
#echo "web1 $1"
$

互信连接建立：

1. 创建密钥对

[root@VM_165_58_tlinux ~]# ssh-keygen

2. 传送公钥到sub server

ssh-copy-id -p 22 -i /root/.ssh/id_rsa.pub root@192.168.100.102
