Server cluster Second Level file synchronization (Ssh+shell)

1. Introduction

\

2. The Business Server remotely updates the script to browse the server files

#!/bin/bashoperate=$1IP=$2Conf_file="/var/www/html/test/ip_list"File_chsum="/var/www/html/test/cksvalue"File_ser="10.60.10.62"cksum () {SSH ${file_ser}"cksum ${conf_file}|awk ' {print\$1} ' > ${file_chsum}"  if[$?-ne0];then #生成cksum值失败 Echo"10005"fi}if[[! $ip =~ ^[0-9]{1,3}\. [0-9]{1,3}\. [0-9]{1,3}\. [0-9]{1,3}$]];then #IP不合法 Echo"10003"; Exit1; Fiif[["${operate}"=="Add"]];then IPs= ' ssh ${file_ser}"cat $conf _file|grep ${ip}/32|wc-l"`  if[${ips}-eq0];then ssh ${file_ser}"Echo"${ip}/ +">> $conf _file"    if[$?-eq0];then cksum #添加IP成功 Echo"10000"Exit0; Else#添加IP失败 Echo"10001"Exit1; FiElse#添加IP成功 (IP already exists) echo"10000"; Exit0; Fielif [["${operate}"=="del"]];then ssh ${file_ser}"sed-i '/${ip}\/32/d ' $conf _file"  if[$?-eq0];then cksum #删除IP成功 Echo"10000"Exit0; Else#删除IP失败 Echo"10002"Exit1; FiElse#参数1 ($1) Not legal echo"10004"Exit1; Fi

3. Browse Server uses HTTP to provide configuration files and Cksum values for browsing and downloading

4.VPS host cluster verifies the Cksum value of the profile every 30 to keep the profile up-to-date

 && sh/tmp/sync_customip.sh && sh/tmp/sync_customip.sh

#!/bin/Bashconf_file_url="http://10.60.10.62:8060/test/ip_list"Cksum_url="Http://10.60.10.62:8060/test/cksvalue"Local_conf_file="/tmp/ip_list" Time=' Date ' log="/tmp/sync_customip.log"get_cksum () {remote_cksum= ' Curl-s"${cksum_url}"' Local_cksum= ' Cksum ${local_conf_file}|awk'{print\$1}''}sync_file () {Cat ${local_conf_file}>/tmp/.
