In an enterprise, there are many servers, and a cluster, such as a website directory, needs to be synchronized. When the environment was just set up, it was impossible to write one file at a time or copy it to the server one by one. Here I wrote a script to automatically move files and copy the required files to the newly built server.
#!/bin/bash
#Auto change server files
#Author kanghui 2016-06-17
#Source server 192.168.33.10
#Target server 192.168.33.14
if [ ! -f ip.txt ];then
echo -e "\033[33mplease create ip.txt files,the ip.txt contents as follows: \033[0m"
cat <<EOF
192.168.149.128
192.168.149.129
EOF
exit
be
if
[ -z "$1" ];then
#This will prompt you to enter and exit the source file directory, here we can do a key-free login
#ssh-keygen keep pressing Enter, then copy the key to the target server
#ssh-copy-id -i /root/.ssh.id_rsa.pub 192.168.33.14 Enter yes and the password will not be entered again
#ssh-copy-id -i /root/.ssh.id_rsa.pub 192.168.33.10 Execute this command locally
#Then execute the script install.log /tmp (install.log is the source file /tmp is the target directory, is it super simple)
echo -e "\033[32m usage: $0 command ,example{Src_Files|Src_Dir} \033[0m"
exit
be
count=`cat ip.txt |wc -l`
rm -rf ip.txt.swp
i=0
#i is less than count, then execute the command inside, 0 meets the requirements and then +1
while ((i< $count))
do
i=`expr $i + 1`
#Print this line, add a mark in front of him, which is 1
sed "${i}s/^/&${i} /g" ip.txt >>ip.txt.swp
IP=`awk -v I="$i" '{if(I=$1)print $2}' ip.txt.swp`
scp -f $1 root@${IP}:$2
#The following code is to keep the two directories consistent. If you want to use the following, just comment out the above one and open the following one.
#For example, execute the command sh auto_scp.sh /tmp/ /tmp/ Here is the original directory and the target directory, if the prompt command is not found, then yu rsync
#rsync -aP --delete $1 root@${IP}:$2
done
