rsync 使用小记

工作中遇到了有关rsync使用的问题，在这里记录下供有同样需求的人参考一下

先说下环境

服务端配置

pid file = /rsyncdata/rsyncd.pid
port = 873
address = 0.0.0.0
charset = UTF-8
reverse lookup = no
uid = 0
gid = 0
use chroot = no
hosts allow = 127.0.0.1 10.10.0.0/255.255.0.0
log format = %o %h [%a] %m (%u) %f %l
log file = /rsyncdata/logs/rsyncd.log
read only = no
max connections = 1000
transfer logging = yes
exclude = lost+found/
fake super = yes
timeout = 900

# sub config

[mysql-back]
path = /rsyncbak/dbback/mysql-back
comment = mysql-back
read only = no
auth users = backuser
hosts allow = *
secrets file = /etc/rsync.password
dont compress = *.gz *.bz2 *.tgz *.zip *.rar *.z
log file = /rsyncdata/logs/rsyncd_mysql-back.log

采用密码文件认证的方式传输，客户端要保证密码文件存在，且权限为600

客户端待传输的目录结构为/mysql/backup/${port}/data/${date}

需求是，将${port}下的最新备份集传输到rsync server，但是server端如果不存在上级目录${port}/data则自动创建

使用喧嚣 R可以实现这一目的，所以最终的传输命令为

cd /mysql/backup
/usr/bin/rsync -avrPR ./${port}/data/${lastest_date} backuser@${rsync_server}::mysql-back --password-file=/etc/rsync.password
