为实现一键发布，最好是可以免密码登陆服务器，通过创建RSA密钥对，将公钥写入目标服务器来实现免密登陆，参考这里。

一键发布

发布脚本 deploy.sh

#!/bin/sh

currentDir=`cd ..;pwd`
localJarDir="${currentDir}/target/"

# package send/receive/mail service
packageApp(){
    cd ${currentDir}/send-service/
    mvn package

    cd ${currentDir}/receive-service/
    mvn package

    cd ${currentDir}/mail-service/
    mvn package 

    # copy to target directory
    if [ ! -d "$localJarDir" ]; then
        mkdir -p ${localJarDir}
    fi

    echo "copy jar to $localJarDir"
    cp ${currentDir}/send-service/target/*.jar ${localJarDir}
    cp ${currentDir}/receive-service/target/*.jar ${localJarDir}
    cp ${currentDir}/mail-service/target/*.jar ${localJarDir}
}

# upload & restart application
appPath="/app/jar/"
appBackPath="/app/jar/backup/"
user="hello"
aliEcs1="1.1.1.134"
aliEcs2="1.1.1.135"

# shutdown application
shutdownApp(){
ssh -tt ${user}@$1<<EOF
    cd ${appPath}
    sh shutdown.sh
    exit
EOF
}

# start application
startApp(){
ssh -tt ${user}@$1<<EOF
    cd ${appPath}
    sh startup.sh
    exit
EOF
}

# backup application
# ssh -tt ${user}@$1<<EOF
#   cd $appPath
#   jarFileList=`ls | grep jar | awk '{print $1}'`
#   for file in $jarFileList; do
#       if [ -f $file ]; then
#           cp $file $appBackPath
#       fi
#   done
#   exit
# EOF
# ssh $user@$1 'for i in /app/jar/*.jar ; do echo $i; done'
# fileDate=`date -r $file '+%Y-%m-%d' | awk '{print $1}'`
# cp $file "$appBackPath/$file.$fileDate"
backupApp(){
ssh -tt ${user}@$1<<EOF
cd ${appPath}
sh backup.sh
exit
EOF
}

# upload to server
# ftp or sftp
uploadFile(){
sftp ${user}@$1<<EOF
  put -r ${localJarDir}*.jar ${appPath}
  quit
EOF
}

# deployApp $aliEcs1
deployApp(){
    shutdownApp $1
    backupApp $1
    uploadFile $1
    startApp $1
}

echo "********************************************** Package app application **********************************************"
packageApp

echo "********************************************** Deploy app to AliECS 1 **********************************************"
deployApp ${aliEcs1}

echo "********************************************** Deploy app to AliECS 2 **********************************************"
deployApp ${aliEcs2}

启停脚本

startup.sh

#!/bin/sh

app_version="0.1.0"
profile_active="prod"
#profile_active="test"

java_cmd="nohup java -jar -Duser.language=en -Dspring.profiles.active=${profile_active}"

echo "Start send service."
${java_cmd} send-service-${app_version}.jar > send-service.log &
sleep 2s

echo "Start receive service."
${java_cmd} receive-service-${app_version}.jar > receive-service.log &
sleep 3s

echo "Start mail service."
${java_cmd} mail-service-${app_version}.jar > mail-service.log &

shutdown.sh

#!/bin/sh

send_service_id=`ps -ef|grep send-service |grep -v grep | gawk '{print $2}'`
receive_service_id=`ps -ef|grep receive-service |grep -v grep | gawk '{print $2}'`
mail_service_id=`ps -ef|grep mail-service |grep -v grep | gawk '{print $2}'`

echo "Start to shutdown send service."
kill -9 ${send_service_id}

echo "Start to shutdown receive service."
kill -9 ${receive_service_id}

echo "Start to shutdown mail service."
kill -9 ${mail_service_id}

备份脚本

backup.sh

#!/bin/sh

appPath="/app/jar/"
appBackPath="/app/jar/backup/"

cd ${appPath}
jarFileList=`ls | grep jar | awk '{print $1}'`
for file in ${jarFileList}; do
    fileDate=`date -r ${file} '+%Y-%m-%d' | awk '{print $1}'`
    if [[ -f ${file} ]]; then
        mv ${file} "$appBackPath$file.$fileDate"
    fi
done

转移历史文件

#!/bin/bash

#待转出文件所在目录
spath='/ap/spath/'
#目标目录
dpath='/ap/dpath/'
#多少天前的文件
days=30

if [ ! -d "$dpath" ]; then
    mkdir -p $dpath
fi

cd "$spath"

#查找30天之前的文件
fileList=`find $spath* -mtime +$days |awk '{print $1}'`
for file in $fileList
do 
if [ -f $file ]; then
    mv $file $dpath
fi
done
