2.安装rsync

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

3.配置rsync服务端

  1. [root@sy-gmh-sa-vm5:/data]# egrep -v "#|^$" /etc/rsyncd.conf 
  2. uid = root
  3. gid = root
  4. use chroot = no
  5. max connections = 200
  6. strict modes =yes
  7. port = 873
  8. [backup]
  9. path = /data/backup/
  10. read only = no
  11. secrets file = /etc/rsync.d/backup.aus

4.配置xinetd

  1. [root@sy-gmh-sa-vm5:~]# cat /etc/xinetd.d/rsync
  2. service rsync
  3. {
  4.     disable = yes
  5.     flags = IPv6 
  6.     socket_type = stream

5.启动服务端并开机自启

  1. [root@sy-gmh-sa-vm5:~]# systemctl enable rsyncd
  2. Created symlink from /etc/systemd/system/multi-user.target.wants/rsyncd.service to /usr/lib/systemd/system/rsyncd.service.
  3. [root@sy-gmh-sa-vm5:~]# systemctl start rsyncd
  4. [root@sy-gmh-sa-vm5:~]# systemctl status rsyncd

6.客户端测试上传备份

  1. # 先安装rsync工具
  2. [root@sy-gmh-sa-vm3:~]# yum install rsync -y
  4. # 第3部分的 /etc/rsync.d/backup.aus 里面的密码要搞到客户端
  5. [root@sy-gmh-sa-vm3:~]# mkdir /etc/rsync.d
  6. [root@sy-gmh-sa-vm3:~]# vim /etc/rsync.d/backup.aus
  7. [root@sy-gmh-sa-vm3:~]# cat /etc/rsync.d/backup.aus
  8. l84F2YPEhPOCtfcsdfafdok
  9. [root@sy-gmh-sa-vm3:~]# chown root.root /etc/rsync.d/backup.aus
