强大的rsync

server1 与 server2 同步

rsync 不仅仅速度快，-a参数可将server端文件权限、属主全部照搬到client端。而且不占服务器资源

### server1 配置  //作为server
[root@server1 solr]# cat /etc/rsyncd.conf
uid = nobody
gid = nobody
hosts allow = 192.168.0.4
use chroot = no
read only = no
secrets file = /etc/rsyncd.secrets  #密码存在哪个文件
log file = /var/log/rsyncd.log
pid file = /var/run/rsyncd.pid

[data]
path = /var/www/html/data

[root@server1 solr]# rsync --daemon

##server2 配置 //作为client
[root@webserver2 solr]# rsync -auz --delete 192.168.0.3::data /var/www/html/data
