网站防篡改脚本

Posted 2021-01-08

这是我生产中所用的防篡改脚本需要的拿走点赞.

扫描定义的数组目录的所有文件的MD5值，然后在用下面个脚本对比
1.2.2.4 扫描deploy目录的md5值脚本
[[email protected] scripts]# cat md5sum_check.sh
#!/bin/sh
path=(
/deploy/factory/tomcat/webapps
/deploy/passport/tomcat/webapps
/deploy/uniring/tomcat/webapps
/deploy/oms/tomcat/webapps
/deploy/rad/tomcat/webapps
/deploy/dubbo/tomcat/webapps
/deploy/nginx
)
[ -d /md5 ] || mkdir /md5 -p
md5_log=/md5/md5_$(date +%F).log
num_log=/md5/num_$(date +%F).log
LANG=en
for n in ${path[*]}
do
    if [ ! -z $n ];then
       find ${path[*]} -type f |xargs md5sum >$md5_log
       find ${path[*]} -type f >$num_log
    else
       exit 1
    fi

done

下面这个脚本放到定时任务每天晚上检测如果有异常就邮件报警
对比deploy下指定的目录如果异常发送邮件
[[email protected] scripts]# cat md5_detection.sh
#!/bin/sh
path=(
/deploy/factory/tomcat/webapps
/deploy/passport/tomcat/webapps
/deploy/uniring/tomcat/webapps
/deploy/oms/tomcat/webapps
/deploy/rad/tomcat/webapps
/deploy/dubbo/tomcat/webapps
/deploy/nginx
)
[ -d /md5 ] || mkdir -p /md5
md5_log=/md5/md5_$(date +%F).log
num_log=/md5/num_$(date +%F).log
num=$(cat $num_log|wc -l)
LANG=EN

while true
    do
    log=/md5/check.log
    [ ! -f $log ] && touch $log
    md5_count=$(md5sum -c $md5_log 2>/dev/null |grep FAILED|wc -l)
    md5_FAILED=$(md5sum -c $md5_log 2>/dev/null |grep FAILED)
    echo $md5_FAILED >>$log

    for n in ${path[*]}
       do
       if [ ! -z $n ];then
          num_count=$(find ${path[*]} -type f |wc -l)
          find ${path[*]} -type f >/md5/new.log
       fi
       done

    if [ $md5_count -ne 0 ] || [ $num_count -ne $num ];then
        #if [ $md5_count -ne 0 ];then
       diff $num_log /md5/new.log >>$log
           mail -s "web site is misrepresented in $(date +%F %T)"  QQ邮箱[email protected] <$log
           exit 0
        else 
           exit 3
    fi
      done
