shell ssh远程部署多台服务器脚本

 

由于项目每天都需要更新版本到多台服务器，为了节省时间和精力，特写脚本来代替重复性操作。

步骤

1、ssh-keygen -t rsa 命令本地机器生成密钥对

Generating public/private rsa key pair.
Enter file in which to save the key (/websphere/wasadmin/.ssh/id_rsa): 
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /websphere/wasadmin/.ssh/id_rsa.
Your public key has been saved in /websphere/wasadmin/.ssh/id_rsa.pub.
The key fingerprint is:
97:0a:5a:15:c3:a5:1b:1a:b1:24:1d:5b:84:60:5c:70 wasadmin@CNSZ443817
The key's randomart image is:
+--[ RSA 2048]----+
|   .==E==..      |
|   ..+o=.+       |
|      + +        |
|       + o .     |
|      + S o      |
|     o . o       |
|    .   .        |
|                 |
|                 |
+-----------------+

2、scp ~/.ssh/id_rsa.pub  user@remoteip:~/.ssh/authorized_keys 将本地生成的公钥拷贝到远程服务器上，从而实现从本地可以无密码访问远程服务器。

3、本地脚本实现将应用报拷贝到远程服务器，并在远程服务器上生成开关文件。shell脚本如下：

trigger()
{
echo "begin trigger $1"
echo "begin trigger $2"
scp /fbs/deploy/ISBS.war $1:$2
ssh user@$1 >/dev/null 2>&1 << eeooff
>/tmp/_FBS_Deploy_Swith_$3
exit
eeooff
echo "trigger $1 done!"
}

trigger remote /fbs/apps/ISBS_war.ear/ISBS.war B

 

4、远程服务器端shell脚本循环检查开关文件是否存在，当存在时，将was应用服务停止并将应用包进行解压，然后再自动启动was服务

while true
do
        sleep 60

        if [ -r /tmp/_FBS_Deploy_Swith_B ];then
                echo    "Begin to deploy\n"

                > ./FBSDeploy.log
                rm /tmp/_FBS_Deploy_Swith_B
                /websphere/IBM/WebSphere/AppServer/profiles/AppSrv01/bin/stopServer.sh server1 -username wasadmin -password wasadmin -nowait
                cd /fbs/apps/ISBS_war.ear/ISBS.war
                jar -xvf ISBS.war
                /websphere/IBM/WebSphere/AppServer/profiles/AppSrv01/bin/startServer.sh server1

                echo "deploy success\n"
        fi
done
