我的是windows环境，目前开发的过程中，有些项目需要一下子部署到很多的linux服务器上。写了个脚本能够自动上传文件和执行部署任务。完成这个任务需要的条件包括SSH配置和一个执行脚本。
准备
1. 本地环境配置
install scp
install cygwin
2. SSH setting
step1: install openSSH
find the cygwin installation application like setup-x86_64.exe and double click to install the openSSH, search the openSSH
and you will find the openSSH package and click next to setup the package
step2: produce a ssh key
open the cygwin window to generate and ssh key using
ssh-keygen
also, you can append with some params to generate a ssh key but it's ok for us now.
you can find a hidden file in the current folder called .ssh and there are two files id_rsa id_rsa.pub
step 3: create connection between local and the remote server
here we'll login to the remote server without password using
ssh-copy-id username@ipaddress
explanation:
username is what you login with to the remote server
ipaddress is the target remote server's ip
answering yes to the questions and finally you can try to login the remote server with comman like
ssh username@ipaddress -p port
you can omit the port if you are using the default port number 22
step4: create an exec script for deployment
If you are not familiar with shell, so you have to read basic about this. I'll give an demonstrator without explaining. here's the code of deploy_test file
#! /bin/bash
tests=(ip1 ip2 ip3)
length=${#tests[@]}
for ((i=0; i<$length; i++))
do
node=${tests[$i]}
echo $node
# copy file to test server
scp /cygdrive/d/git/test.zip $node:~
# operation to mv the etcd file and restart the etcd service
#first step to backup the previous version of test
ssh $node "sudo mv /opt/app/testrepo/test.zip /opt/app/etcdrepo/testbak/"
#stop the etcd service
ssh $node "sudo mv /home/op2/test.zip /opt/app/testrepo "
done
step5: make script work out
exec the script using command
./deploy_test
Congratulations! You make it. Great!
