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192.168.168.5CentOS 7.6.1810 (Core)
rsync客户端192.168.168.3CentOS 7.6.1810 (Core)

2.安装rsync

[root@sy-gmh-sa-vm5:/data]# yum install -y rsync xinetd

3.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 save

4.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 xinetd

5.启动服务端并开机自启

[root@sy-gmh-sa-vm5:~]# systemctl enable rsyncd
Created symlink from /etc/systemd/system/multi-user.target.wants/rsyncd.service to /usr/lib/systemd/system/rsyncd.service.
[root@sy-gmh-sa-vm5:~]# systemctl start rsyncd
[root@sy-gmh-sa-vm5:~]# systemctl status rsyncd
● rsyncd.service - fast remote file copy program daemon
   Loaded: loaded (/usr/lib/systemd/system/rsyncd.service; enabled; vendor preset: disabled)

 Main PID: 10361 (rsync)
   CGroup: /system.slice/rsyncd.service
           └─10361 /usr/bin/rsync --daemon --no-detach

6月 27 07:03:04 sy-gmh-sa-vm5.shaoyan.pro systemd[1]: Started fast remote file copy program daemon.
6月 27 07:03:04 sy-gmh-sa-vm5.shaoyan.pro rsyncd[10361]: rsyncd version 3.1.2 starting, listening on port 873

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-vm3:~]# 

[root@sy-gmh-sa-vm3:~]# du -h data/

[root@sy-gmh-sa-vm3:~]# /usr/bin/rsync -vzrtopg --progress --password-file=/etc/rsync.d/backup.aus /root/data root@192.168.168.5::backup

确认文件

[root@sy-gmh-sa-vm5:~]# ls /data/backup/data/ -lh
总用量 0
drwxr-xr-x 3 root root 68 6月 21 08:59 01DDMX1BWQ3R2MSVHDBCB2YXPX
drwxr-xr-x 3 root root 68 6月 21 09:00 01DDVRRKX1PPS0ADSQ496XXTXS

drwxr-xr-x 2 root root 22 6月 18 08:02 wal
[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。
