rysnc

1、server client 模式

[root@dbback ~]# tree /etc/rsyncd/
/etc/rsyncd/
├── rsyncd.conf
├── rsyncd.motd
└── rsyncd.secrets

0 directories, 3 files

[root@dbback ~]# vim /etc/rsyncd/rsyncd.conf 

uid = root 
gid = root
user chroot = no
max connections = 200
timeout = 600
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsyncd.lock
log file = /var/log/rsyncd.log
[data]
path=/klkj_back/oracle/
ignore errors = yes
read only = no
list = no
hosts allow = 192.168.10.5
auth users = orcl 不是系统用户
secrets file = /etc/rsyncd/rsyncd.secrets


[root@dbback ~]# cat /etc/rsyncd/rsyncd.secrets 
orcl:orcl

which rsync查看路径
/usr/bin/rsync --daemon --config=/etc/rsyncd/rsyncd.conf

client 
rsync -av  --progress  --password-file=rsyncd.pass linux.x64_11gR2_database_1of2.zip orcl@10.10.5.16::data
client password file mode 600
client  ip 要在server hosts allow 中不然会提示Unknown module
server 中的uid 要有对path的读写权限，写会提示 failed: Permission denied

2、用过ssh

rsync -av  --progress   linux.x64_11gR2_database_1of2.zip backuser@10.10.5.16:/home/backuser
ssh: connect to host 10.10.5.16 port 22: Connection refused
默认用的ssh 端口是22我的端口是24116

rsync -av  --progress  -e 'ssh -p24116' linux.x64_11gR2_database_1of2.zip backuser@10.10.5.16:/home/backuser
The authenticity of host '[10.10.5.16]:24116 ([10.10.5.16]:24116)' can't be established.
RSA key fingerprint is 10:2e:c6:f9:8a:09:ae:bf:4b:c0:ba:50:14:68:51:e3.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '[10.10.5.16]:24116' (RSA) to the list of known hosts.
backuser@10.10.5.16's password:

total size is 1239269270  speedup is 1.00
通过-e 来指定端口 backuser是系统用户

3、xinetd

[root@dbback ~]# vim /etc/xinetd.d/rsync 

# default: off
# description: The rsync server is a good addition to an ftp server, as it \
#       allows crc checksumming etc.
service rsync
{
        disable = no  yes改no
        socket_type     = stream
        wait            = no
        user            = root
        server          = /usr/bin/rsync
        server_args     = --daemon --config=/etc/rsyncd/rsyncd.conf
        log_on_failure  += USERID
}
