四、shell 编程实战案例

4.1 系统备份脚本—案例

Tar工具全备、增量备份网站，Shell脚本实现自动打包备份：

 #!/bin/bash
    #Auto Backup Linux System Files
    #by author rivers on 2021-09-28

  SOURCE_DIR=(
        $*
    )
    TARGET_DIR=/data/backup/
    YEAR=`date +%Y`
    MONTH=`date +%m`
    DAY=`date +%d`
    WEEK=`date +%u`
    A_NAME=`date +%H%M`
    FILES=system_backup.tgz
    CODE=$?
    if
        [ -z "$*" ]；then
        echo -e "\033[32mUsage:\nPlease Enter Your Backup Files or Directories\n--------------------------------------------\n\nUsage: { $0 /boot /etc}\033[0m"
        exit
    fi
    #Determine Whether the Target Directory Exists
    if
        [ ! -d $TARGET_DIR/$YEAR/$MONTH/$DAY ]；then
        mkdir -p $TARGET_DIR/$YEAR/$MONTH/$DAY
        echo -e "\033[32mThe $TARGET_DIR Created Successfully !\033[0m"
    fi
    #EXEC Full_Backup Function Command
    Full_Backup()
    {
    if
        [ "$WEEK" -eq "7" ]；then
        rm -rf $TARGET_DIR/snapshot
        cd $TARGET_DIR/$YEAR/$MONTH/$DAY ；tar -g $TARGET_DIR/snapshot -czvf $FILES ${SOURCE_DIR[@]}
        [ "$CODE" == "0" ]&&echo -e  "--------------------------------------------\n\033[32mThese Full_Backup System Files Backup Successfully !\033[0m"
    fi
    }
    #Perform incremental BACKUP Function Command
    Add_Backup()
    {
       if
            [ $WEEK -ne "7" ]；then
            cd $TARGET_DIR/$YEAR/$MONTH/$DAY ；tar -g $TARGET_DIR/snapshot -czvf $A_NAME$FILES ${SOURCE_DIR[@]}
            [ "$CODE" == "0" ]&&echo -e  "-----------------------------------------\n\033[32mThese Add_Backup System Files $TARGET_DIR/$YEAR/$MONTH/$DAY/${YEAR}_$A_NAME$FILES Backup Successfully !\033[0m"
       fi
    }
    sleep 3 
    Full_Backup；Add_Backup

4.2 收集系统信息—案例

Shell脚本实现服务器信息自动收集：

 cat <<EOF
    ++++++++++++++++++++++++++++++++++++++++++++++
    ++++++++Welcome to use system Collect+++++++++
    ++++++++++++++++++++++++++++++++++++++++++++++
    EOF
    ip_info=`ifconfig |grep "Bcast"|tail -1 |awk '{print $2}'|cut -d: -f 2`
    cpu_info1=`cat /proc/cpuinfo |grep 'model name'|tail -1 |awk -F: '{print $2}'|sed 's/^ //g'|awk '{print $1,$3,$4,$NF}'`
    cpu_info2=`cat /proc/cpuinfo |grep "physical id"|sort |uniq -c|wc -l`
    serv_info=`hostname |tail -1`
    disk_info=`fdisk -l|grep "Disk"|grep -v "identifier"|awk '{print $2,$3,$4}'|sed 's/,//g'`
    mem_info=`free -m |grep "Mem"|awk '{print "Total",$1,$2"M"}'`
    load_info=`uptime |awk '{print "Current Load: "$(NF-2)}'|sed 's/\,//g'`
    mark_info='BeiJing_IDC'
    echo -e "\033[32m-------------------------------------------\033[1m"
    echo IPADDR:${ip_info}
    echo HOSTNAME:$serv_info
    echo CPU_INFO:${cpu_info1} X${cpu_info2}
    echo DISK_INFO:$disk_info
    echo MEM_INFO:$mem_info
    echo LOAD_INFO:$load_info
    echo -e "\033[32m-------------------------------------------\033[0m"
    echo -e -n "\033[36mYou want to write the data to the databases? \033[1m" ；read ensure


    if      [ "$ensure" == "yes" -o "$ensure" == "y" -o "$ensure" == "Y" ];then
            echo "--------------------------------------------"
            echo -e  '\033[31mmysql -uaudit -p123456 -D audit -e ''' "insert into audit_system values('','${ip_info}','$serv_info','${
    cpu_info1} X${cpu_info2}','$disk_info','$mem_info','$load_info','$mark_info')" ''' \033[0m '
            mysql -uroot -p123456 -D test -e "insert into audit_system values('','${ip_info}','$serv_info','${cpu_info1} X${cpu_info2}
    ','$disk_info','$mem_info','$load_info','$mark_info')"
    else
            echo "Please wait，exit......"
            exit
    fi

4.3 一键部署lnmp架构—案例

批量部署lnmp 架构：
