一个简单的连续调用脚本部署代码的案例

先简单描述一下环境，Jenkins部署在私有云，从git拉取代码并编译后会调用脚本将jar包部署到阿里云的应用服务器。
阿里云应用服务器无公网IP，通过跳板机登录。就产生了连续调用脚本，穿透跳板机部署到阿里云内网的需求。

拓扑图如下：

1.部署脚本01-backend-earphone-8888.sh (Jenkins server)

主要实现功能：

• 将跳板机1.1.1.1上面临时目录/data/deploy/pccode/earphone内容情况
• 拷贝Jenkins编译生成的jar包文件（earphone-1.08888.jar）至跳板机/data/deploy/pccode/earphone目录
• 调用跳板机脚本进行部署/data/deploy/script/earphone.sh

[root@bobo365 prod]# more backend-earphone-8888.sh

#!/bin/bash

. /etc/init.d/functions

node="1.1.1.1"

current="/home/bobo365/scripts/prod"

dest_user='remote'
dest_passwd='xxxxxxx'
package_name="earphone-1.08888.jar"
source_dir="${JENKINS_HOME}/jobs/${PROMOTED_JOB_NAME}/builds/${PROMOTED_NUMBER}/archive"
source_file="${PROMOTED_JOB_NAME}/builds/${PROMOTED_NUMBER}/archive/$package_name"
dest_temp="/data/deploy/pccode/earphone"
back_dir="/data/backup"
shell_dir="/data/deploy/script"
shell="earphone.sh"
back_prog="backend-earphone"
back_time=`date +"%Y-%m-%d-%s"`

NOW=`date +"%Y/%m/%d %T"`

echo "Clean the dir."
sshpass -p $dest_passwd ssh $dest_user@$node -p 22 -o StrictHostKeychecking=no "rm -rf '$dest_temp'/*" 

    if [ $? = 0 ]
    then
        echo $node $NOW clean the dir success | tee -a $current/logs/backend-earphone.log
    else
        echo $node $NOW clean the dir failed | tee -a $current/logs/backend-earphone.log
        echo  >> $current/backend-earphone.log
        exit 1
    fi

echo "Scp the file."
sshpass -p $dest_passwd scp -P22 -o StrictHostKeyChecking=no $source_dir/$package_name $dest_user@$node:$dest_temp/$package_name 

    if [ $? = 0 ]
    then
        echo $node $NOW scp code success | tee -a $current/logs/backend-earphone.log
    else
        echo $node $NOW scp code failed | tee -a $current/logs/backend-earphone.log
        echo  >> $current/backend-earphone.log
        exit 1
    fi

echo "Deploy the file."
sshpass -p $dest_passwd ssh $dest_user@$node -p 22 -o StrictHostKeychecking=no "/bin/bash $shell_dir/$shell" 

    if [ $? = 0 ]
    then
        echo $node $NOW deploy code success | tee -a $current/logs/backend-earphone.log
    else
        echo $node $NOW deploy code failed | tee -a $current/logs/backend-earphone.log
        echo  >> $current/backend-earphone.log
        exit 1
    fi

NOW=`date +"%Y/%m/%d %T"`
echo -e "$NOW: $prog complete of deploy ."

2.部署脚本02-earphone.sh (Jump server)

主要实现功能：

• 拷贝文件至应用服务器（/data/deploy/pccode/earphone/earphone-1.08888.jar）
• 调用应用服务器脚本（restart-headset.sh）进行代码的替换
• 使用ansible
  • more /etc/ansible/hosts

    [promote]
    192.168.2.21
    192.168.2.22

[root@JUMP script]# more earphone.sh

#!/bin/bash

current="/data/deploy/script"
source_dir="/data/deploy/pccode/earphone"
package_name="earphone-1.08888.jar"

ansible promote -m copy -a "src=$source_dir/$package_name dest=/root"

sleep 10

ansible promote -a "/bin/bash /root/restart-headset.sh"

3.部署脚本03-restart-headset.sh （application server）

主要实现功能：

• 删掉现有earphone进程并重新启动

[root@app ~]# more restart-headset.sh

#!/bin/bash
package_name="earphone-1.08888.jar"
PID=`ps -ef|grep 8888|grep -v grep|awk -F " " '{print $2}'`
kill -9 $PID

nohup /usr/local/jdk1.8.0_60/bin/java -jar $package_name &

4.在本例实现过程中，存在很大可以优化的地方

• 脚本过于简单，很多地方缺少判断，健壮性有待提高
• 部署脚本相互引用，过于繁琐，如果出现问题，排错有一定难度
• 跨网络部署是否还有更好的方式，有待学习
