0.环境说明
rsync是什么：
rsync是linux系统下的数据镜像备份工具。使用快速增量备份工具Remote Sync可以远程同步，支持本地复制，或者与其他SSH、rsync主机同步。rsync是典型的CS服务架构，备份机上配置rsync服务端，其他机器作为rsync客户端，向服务端推送备份数据，达到备份目的。
下文，是徒手搭建rsync备份服务器过程。
| 服务角色 | IP | 系统版本 |
|---|---|---|
| rsync服务端 | 192.168.168.5 | CentOS 7.6.1810 (Core) |
| rsync客户端 | 192.168.168.3 | CentOS 7.6.1810 (Core) |
2.安装rsync
[root@sy-gmh-sa-vm5:/data]# yum install -y rsync xinetd3.配置rsync服务端
[root@sy-gmh-sa-vm5:/data]# egrep -v "#|^$" /etc/rsyncd.conf
uid = root
gid = root
use chroot = no
max connections = 200
strict modes =yes
port = 873
[backup]
path = /data/backup/
read only = no
secrets file = /etc/rsync.d/backup.aus
auth users = root
[root@sy-gmh-sa-vm5:/data]# vim /etc/rsync.d/backup.aus
[root@sy-gmh-sa-vm5:/data]# chmod 600 /etc/rsync.d/backup.aus
[root@sy-gmh-sa-vm5:/data]# cat /etc/rsync.d/backup.aus
root:l84F2YPEhPOCtfcsdfafdok
# 放行端口
[root@sy-gmh-sa-vm5:~]# iptables -I INPUT -s 192.168.168.0/24 -p tcp -m tcp --dport 873 -j ACCEPT
[root@sy-gmh-sa-vm5:~]# service iptables save4.配置xinetd
[root@sy-gmh-sa-vm5:~]# cat /etc/xinetd.d/rsync
service rsync
{
disable = yes
flags = IPv6
socket_type = stream
wait = no
user = root
server = /usr/bin/rsync
server_args = --daemon
log_on_failure += USERID
}
[root@sy-gmh-sa-vm5:~]# systemctl enable xinetd
[root@sy-gmh-sa-vm5:~]# systemctl start xinetd5.启动服务端并开机自启
[root@sy-gmh-sa-vm5:~]# systemctl enable rsyncd

6.客户端测试上传备份
# 先安装rsync工具
[root@sy-gmh-sa-vm3:~]# yum install rsync -y
# 第3部分的 /etc/rsync.d/backup.aus 里面的密码要搞到客户端
[root@sy-gmh-sa-vm3:~]# mkdir /etc/rsync.d
[root@sy-gmh-sa-vm3:~]# vim /etc/rsync.d/backup.aus
[root@sy-gmh-sa-vm3:~]# cat /etc/rsync.d/backup.aus
l84F2YPEhPOCtfcsdfafdok
[root@sy-gmh-sa-vm3:~]# chown root.root /etc/rsync.d/backup.aus
[root@sy-gmh-sa-vm3:~]# chmod 600 /etc/rsync.d/backup.aus

[root@sy-gmh-sa-vm5:~]# 确认无误。到此，rsync备份服务器已经可以使用。客户端使用脚本，配合rsync命令就可以备份文件到服务端了。
