一键发布shell脚本

1.配置集群间免密登录

（1）配置host：vim /etc/hosts

（2）生成公钥：ssh-keygen -t rsa -P ''

　　这时会提示生成的公钥的存放地址，直接回车，公钥生成成功

（3）cat id_rsa.pub 将生成的公钥添加到需要登录的机器的authorized_keys文件里

然后直接ssh crawler01即可登录

2.一键启动脚本

 #!/bin/bash

 #程序包名称

 ZIP_NAME="aikucun-distributed-spider-crawler.zip"

 zip_exist(){

     if [ ! -f "$ZIP_NAME" ]

     then

         return

     else

         return

     fi

 }

 backup(){

     echo "备份方法执行..."

     cd ~/crawler

     if zip_exist; then

         mv $ZIP_NAME ~/jar_bak

         echo "crawler程序包备份完成!"

     else

         echo "$ZIP_NAME 不存在，无法备份，请检查！"

     fi

 }

 check_single(){

     if [ ! -f "bin/single.sh" ]

     then

         return

     else

         return

     fi

 }

 stop(){

     echo "停止方法执行..."

     if check_single; then

         sh bin/single.sh stop

         CURRENT_PATH=`cd "$(dirname "$")"; pwd`

         echo "当前所在目录：$CURRENT_PATH"

         rm -rf ~/crawler/*

         echo "已清除旧程序"

     else

         echo "single脚本文件不存在，无法停止程序，请检查程序结构是否完整！"

         exit 1

     fi

 }

 start(){

     echo "开始方法执行..."

     cd ~/jar_new

     if zip_exist; then

         mv $ZIP_NAME ~/crawler

         cd ~/crawler

         unzip -q $ZIP_NAME

         echo "解压程序包完成！"

         cd bin

         dos2unix single.sh

         echo "格式转换完成!"

         sh single.sh start

     else

         echo "$ZIP_NAME 不存在，程序无法发布，请检查！"

         exit 1

     fi

 }

 backup

 stop

 star

3.上传一键启动脚本upload.sh

 #!/bin/bash

 #取当前目录

 BASE_PATH=`cd "$(dirname "$")"; pwd`

 crawler_list="

 crawler02

 crawler03

 crawler04

 crawler05

 crawler06

 crawler07

 crawler08

 crawler09

 crawler10

 crawler11

 crawler12

 crawler13

 crawler14

 crawler15

 "

 for i in $crawler_list

 do

         echo "正在上传一键启动脚本至$i"

         scp $BASE_PATH/publish_crawler.sh $i:~

         echo "$i机器上传完成"

 done

4.一键发布脚本

 #!/bin/bash

 #取当前目录

 BASE_PATH=`cd "$(dirname "$")"; pwd`

 SHELL_NAME="publish_crawler.sh"

 crawler_list="

 crawler02

 crawler03

 crawler04

 crawler05

 crawler15

 "

 for i in $crawler_list

 do

         echo "正在上传程序包至$i"

         scp $BASE_PATH/crawler/aikucun-distributed-spider-crawler.zip $i:~/jar_new

         echo "登录并执行一键启动脚本"

         ssh $i "sh $SHELL_NAME"

 done

5.通用脚本优化

（1）上传一键启动脚本到相应的服务器的脚本

（2）一键启动脚本

（3）一键发布脚本

 #!/bin/bash

 #取当前目录

 BASE_PATH=`cd "$(dirname "$")"; pwd`

 SERVER_LIST=""

 upload(){

 echo "上传服务器列表：$SERVER_LIST"

 for i in $SERVER_LIST

 do

         echo "正在上传一键启动脚本至$i"

         scp $BASE_PATH/publish.sh $i:~

         echo "$i机器上传完成"

6.在原来的基础上进一步优化，增加一键停止功能

（1）上传发布脚本到集群各个服务器的脚本

echo "上传服务器列表：$SERVER_LIST"

for i in $SERVER_LIST

do

        echo "正在上传一键启动脚本至$i"

        scp $BASE_PATH/publish.sh $i:~
