I have quite a few servers, and deploying same files/folders to them is a problem. Then I come up with the following BASH script where I can just run on the master server and it will upload the files or folders to all other slave servers.
In order to avoid entering username/password everytime, we have to put the SSH keys to the ~/.ssh/authorized_keys.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 | #!/bin/bash hosts=( "host1" "host2" ) port=12345 user=root sync() { echo scp -r -P $port $2 $user@$1:$3 scp -r -P $port $2 $user@$1:$3 } if [ -z "$1" ] || [ -z "$2" ] then echo "Syntax $0 file remote_path" exit 1 fi for i in "${hosts[@]}" do sync $i $1 $2 done |
#!/bin/bash
hosts=( "host1" "host2" )
port=12345
user=root
sync() {
echo scp -r -P $port $2 $user@$1:$3
scp -r -P $port $2 $user@$1:$3
}
if [ -z "$1" ] || [ -z "$2" ]
then
echo "Syntax $0 file remote_path"
exit 1
fi
for i in "${hosts[@]}"
do
sync $i $1 $2
doneExample usage:
1 | $./sync /local_files/data.txt /remote_dir/ |
$./sync /local_files/data.txt /remote_dir/
It will copy the local file to the remote_dir of all remote hosts. It is based on scp command.
