rsync作用比较：
远程拷贝：scp
本地拷贝：cp
删除功能：rm
rsync可以是一个网络服务（port socket）
rsync命令是客服端命令：
第一种工作模式：local
rsync -avz /etc/hosts /tmp/ ===cp
rsync -avz --delete /null/ /tmp/ ===rm
第二种工作模式：remote shell
push：
rsync -avzP -e ‘ssh -p 22‘ /tmp/ [email protected]:/tmp
pull:
rsync -avzP -e ‘ssh -p 22‘ [email protected]:/tmp /tmp/
操作流程
1.yum install -y rsync
2.rsync --version
3.touch /etc/rsyncd.conf
4.vi /etc/rsyncd.conf

rsync server:配置步骤
1.vi /etc/rsyncd.conf
#Rsync server
#created by oldboy
##rsyncd.conf start##
uid = rsync
gid = rsync
use chroot =no
max connections =2000
timeout =600
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsync.lock
log file = /var/log/rsyncd.log
ignore errors
read only = false
list = false
hosts allow = 192.168.70.0/24

2.创建rsync用户、共享目录/backup
useradd rsync -s /sbin/nologin -M
id rsync
mkdir /backup
chown -R rsync /backup
ll-d /backup/
3.创建密码文件
echo "rsync_backup:oldboy" >/etc/rsync.password
chmod 600 /etc/rsync.password
4.rsync --daemon
netstat -lntup|grep rsync
ps -ef|grep rsync|grep -v grep
5.加入开机自启动
echo "rsync --daemon" >>/etc/rc.local
cat /etc/rc.local
