1. scp同步文件脚本 //syntest.sh
#!/bin/bash
# Setting cdm path is used to store client softwarehost_dir=”/var/hostdir”# Statement the file is used to store the size of cdm folder sizefsrecord=”.r”# To synchronize the target machine ipclient_ip=”192.168.0.2″# To synchronize the target machine directoryclient_dir=”/var/clientdir”
# Current file folder sizenew_folder_size=”$(du -sh $host_dir |awk ‘{print $1}’)”# Read the size of the folder and remove character ‘M’if [ ! -f $fsrecord ]then echo “0M” > $fsrecordfiold_folder_size=”$(cat $fsrecord|tr -d ‘M’)”# Remove character ‘M’temp_new=”$(echo $new_folder_size|tr -d ‘M’)”
# Compare file folder sizeif [ “$temp_new” != “$old_folder_size” ]then scp -r $host_dir $client_ip:$client_dir echo “” echo “—–The folder has been synchronized success!—–” # Write the latest file folder size echo $new_folder_size > $fsrecordelse echo “—–The folder has not been changed, so it does not need to synchronize.—–“fi
2. 为scp自动拷贝生成不用输入密码的密匙
参考《ssh(scp)自动登录的几种方法》
3. 用crontab定时运行脚本。
1.) 将syntest.sh拷贝到/etc目录下
2.) 编辑crontab,文件在/var/spool/cron/crontabs下
比如：每分钟运行一次
0-59 * * * * /etc/syntest.sh //*/5 每5分钟1次 */20 每20分钟1次 在Linux下可以，，但是在Solaris下不支持
4. refresh crontab
svcadm refresh cron
相信梦想是价值的源泉，相信眼光决定未来的一切，
