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
 crawler06
 crawler07
 crawler08
 crawler09
 crawler10
 crawler11
 crawler12
 crawler13
 crawler14
 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"
 done
 }

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

#!/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"
done
}

case "$1" in

crawler)

    echo "available operations: [crawler|transport|storage|controller]"
    exit

（2）发布脚本
