RSYNC最简实施

只是内网同步，故而可以省略很多安全方面的东东。不需要通过ssh，而是通过rsync协议。不需要用户名认证，保证只读。

rsync用standalone的daemon方式，而不用service方式操作。

由于合规限制，暂时走非标准端口，现在记录一下过程。

一，/etc/rsyncd/rsyncd.conf文件内容：

# Minimal configuration file for rsync daemon
# See rsync(1) and rsyncd.conf(5) man pages for help

# This line is required by the /etc/init.d/rsyncd script
# GLOBAL OPTIONS
uid = root
gid = root                                  

use chroot = no
read only = yes                            

#limit access to private LANs
max connections = 2048                      

pid file = /var/run/rsyncd.pid
lock file = /var/run/rsync.lock
log file = /var/log/rsync.log               

#This will log every file transferred - up to 85,000+ per user, per sync
transfer logging = yes                    

log format = %t %a %m %f %b
syslog facility = local3
timeout = 600

# MODULE OPTIONS
[pppp]
path = /xxxx_vol1/a/b/
list=yes
ignore errors
comment = Package Store

二，启动rsync server:

rsync --daemon --config=/etc/rsyncd/rsyncd.conf  --port=873

三，在客户端同步，注意一下调整参数：

rsync -avWP  --bwlimit=50000  --block-size=512 --timeout=600 --checksum --port=4505 --delete rsync://1.2.3.3/pppp/abc  /tmp/abc/
