说明：
在CentOS7下部署rsync服务和在CentOS6上部署基本上是一样的，只是CentOS7自带了rsyncd启动脚本，由systemd管理而已。
rsync服务端配置
[root@SERVER1 ~]# rpm -qa|grep rsync
rsync-3.0.9-17.el7.x86_64
[root@SERVER1 ~]# uname -r
3.10.0-514.el7.x86_64
[root@SERVER1 ~]# systemctl stop firewalld
[root@SERVER1 ~]# grep -i "selinux=" /etc/selinux/config
# SELINUX= can take one of these three values:
SELINUX=disabled
[root@SERVER1 ~]# rsync --version
rsync version 3.0.9 protocol version 30
[root@SERVER1 ~]# useradd -M -s /sbin/nologin rsync
[root@SERVER1 ~]# mkdir /data/test -p
[root@SERVER1 ~]# chown -R rsync.rsync /data/test
[root@SERVER1 ~]# vim /etc/rsyncd.conf

##rsyncd.conf start## uid = rsync
gid = rsync
use chroot = no
max connections = 200
timeout = 300
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsync.lock
log file = /var/log/rsyncd.log

hosts allow = *
hosts deny = 0.0.0.0/32
auth users = rsync_backup
secrets file = /etc/rsync.password #rsync_config_______________end [root@SERVER1 ~]# echo 'rsync_backup:123456' >/etc/rsync.password
[root@SERVER1 ~]# chmod 600 /etc/rsync.password
[root@SERVER1 ~]# systemctl restart rsyncd
[root@SERVER1 ~]# ss -lntup|grep rsync

客户端配置
[root@opvnserver ~]# uname -r

[root@opvnserver ~]# cat /etc/redhat-release
CentOS Linux release 7.5.1804 (Core)
[root@opvnserver ~]# systemctl stop firewalld
