rsync

实例：从服务器 A 将目录 /home/someone/sth 上的内容，传输到服务器 B 的 /home/someone/upload


=== 服务器 B 上 rsyncd 的设置 ===

1. 设置 rsyncd.conf
$ pwd
/home/someone/rsyncd

$ cat rsyncd.conf
uid = nobody
gid = nobody
use chroot = no
max connections = 4

pid file  = /home/someone/rsyncd/run/rsyncd.pid
lock file = /home/someone/rsyncd/run/rsync.lock
log file  = /home/someone/rsyncd/log/rsyncd.log

secrets file = /home/someone/rsyncd/rsyncd.pwd

[tagname]
path = /home/someone/upload
read only  = false
write only = true
list = false
auth users = test

2. 创建 rsyncd.pwd
$ echo "test:testpwd" > rsyncd.pwd
$ chmod 600 rsyncd.pwd

3. 启动 rsyncd
rsync -4 --verbose --daemon --port=8730 --config=/home/someone/rsyncd/rsyncd.conf


=== 服务器 A ===

1. 创建 test.pwd
$ pwd
/home/someone
$ echo "testpwd" > test.pwd         # 注意这里, 并不需要 user, 只需要 passwd 信息即可
$ chmod 600 test.pwd

2. 传输数据
$ rsync --recursive --password-file=/home/someone/test.pwd --port=8730 /home/test/sth test@server_B_ip::tagname

~~~~~~~~~~~~~`
如此这般，就可在服务器B /home/someone/upload/sth 这里找到所有内容啦。
