先在主控机执行ssh-keygen，再向被控机传输key，
ssh-copy-id -i ~/.ssh/id_rsa.pub user1@ip
样例脚本transfer-artemis.sh如下：
#!/bin/bash
loop_server(){
for ((i=2; i<=8; i++))
do
ipd=10.10.31.1${i}2
echo ${ipd}
$1 ${ipd}
done
for ((i=1; i<=2; i++))
do
ipd=10.20.31.1${i}2
echo ${ipd}
$1 ${ipd}
done
}
start_artemis_cmd(){
echo "ssh user1@${1} '/opt/myapp/artemis/apache-artemis-2.15.0/instance/bin/artemis-service start'"
ssh user1@${1} '/opt/myapp/artemis/apache-artemis-2.15.0/instance/bin/artemis-service start'
}
stop_artemis_cmd(){
echo "ssh user1@${1} '/opt/myapp/apache-activemq-5.15.10/bin/activemq stop'"
echo "ssh user1@${1} '/opt/myapp/artemis/apache-artemis-2.15.0/instance/bin/artemis-service stop'"
ssh user1@${1} '/opt/myapp/apache-activemq-5.15.10/bin/activemq stop'
ssh user1@${1} '/opt/myapp/artemis/apache-artemis-2.15.0/instance/bin/artemis-service stop'
}
scp_artemis_cmd(){
echo "ssh user1@${1} 'rm -rf /opt/myapp/artemis'"
echo "scp -r /opt/myapp/artemis user1@${1}:/opt/myapp/"
ssh user1@${1} 'rm -rf /opt/myapp/artemis'
scp -r /opt/myapp/artemis user1@${1}:/opt/myapp/
}
stop_artemis(){
loop_server stop_artemis_cmd
}
start_artemis(){
loop_server start_artemis_cmd
}
scp_artemis(){
loop_server scp_artemis_cmd
}
#start_artemis "Hello start_artemis"
$1
执行命令：
./transfer-artemis.sh start_artemis
