部署环境准备

[root@nfs ~]# cat /etc/redhat-release
CentOS Linux release 7.7.1908 (Core)
[root@nfs ~]# uname -r
3.10.0-1062.el7.x86_64
[root@nfs ~]# uname -m
x86_64
[root@nfs ~]# rpm -qa rsync
rsync-3.1.2-10.el7.x86_64

1》 配置rsync.conf

 uid = rsync
 gid = rsync
 fake super = yes
 use chroot = no
 max connections = 200
 timeout = 600
 pid file = /var/run/rsyncd.pid
 lock file = /var/run/rsync.lock
 log file = /var/log/rsync.log
 ignore errors
 read only = false
 list = false
 host allow = 10.64.64.226/24
 auth users = rsync_backup
 secrets file = /etc/rsync.password
 [backup]
 cpmment = welcome to huang backup!
 path = /backup/
 #注释去掉

2》配置用于数据备份的目录

[root@backup ~]# useradd rsync -s /sbin/nologin -M		#创建管理备份目录的用户
[root@backup ~]# mkdir -p /backup						#创建backup备份目录
[root@backup ~]# chown -R rsync.rsync /backup			#授权rsync用户和组管理backup用户

3》配置用于Rsync复制的账号、密码及帐号文件权限

[root@backup ~]# echo "rsync_backup:huang" >/etc/rsync.password
[root@backup ~]# chmod 600 /etc/rsync.password

检查认证文件信息的命令如下

[root@backup ~]# cat /etc/rsync.password
rsync_backup:huang
[root@backup ~]# ll /etc/rsync.password
