[root@bakcup ~]# rpm -qa rsync
rsync-3.0.6-12.el6.x86_64

生成rsyncd.conf配置文件

[root@bakcup ~]# vim /etc/rsyncd.conf

添加rsync服务的用户，管理本地目录

[root@bakcup ~]# id rsync
id: rsync: No such user
[root@bakcup ~]# useradd rsync -s /sbin/nologin -M 
[root@bakcup ~]# tail -1 /etc/passwd
rsync:x:501:501::/home/rsync:/sbin/nologin

启动rsync服务并检查

[root@bakcup ~]# rsync --daemon
[root@bakcup ~]# ps -ef|grep rsync|grep -v grep
root       4214      1  0 00:13 ?        00:00:00 rsync --daemon

创建共享的目录并授权rsync服务管理

[root@bakcup ~]# mkdir /backup
[root@bakcup ~]# ls -ld /backup/
drwxr-xr-x 2 root root 4096 Feb  4 00:15 /backup/
[root@bakcup ~]# chown rsync.rsync /backup/
[root@bakcup ~]# ls -ld /backup/           
drwxr-xr-x 2 rsync rsync 4096 Feb  4 00:15 /backup/

根据rsync.conf的auth users配置账户，远程连续的，并生成密码文件

[root@bakcup ~]# ll /etc/rsync.password
ls: cannot access /etc/rsync.password: No such file or directory
[root@bakcup ~]# vim /etc/rsync.password   #<==或者用 echo "rsync_backup:oldboy" >/etc/rsync.password
rsync_backup:oldboy
~

~

[root@bakcup ~]# cat /etc/rsync.password
rsync_backup:oldboy #<==为同步传输用的虚拟账号，仅为rsync的账号，不需要是系统账号。后面的oldboy是密码，不超过8位，账号和密码用冒号分割
[root@bakcup ~]# ls /etc/rsync.password -l
-rw-r--r-- 1 root root 20 Feb  4 00:22 /etc/rsync.password

为密码文件配置权限

[root@bakcup ~]# chmod 600 /etc/rsync.password 
[root@bakcup ~]# ls /etc/rsync.password -l     
-rw------- 1 root root 20 Feb  4 00:22 /etc/rsync.password

[root@bakcup ~]# lsof -i :873  #<==根据端口找出服务名
COMMAND  PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
rsync   4214 root    4u  IPv6  19781      0t0  TCP *:rsync (LISTEN)
rsync   4214 root    5u  IPv4  19782      0t0  TCP *:rsync (LISTEN)
[root@bakcup ~]# netstat -lntup|grep 873

加入开机自启动

[root@bakcup ~]# echo "/usr/bin/rsync --daemon" >>/etc/rc.local   
[root@bakcup ~]# tail -1 /etc/rc.local
/usr/bin/rsync --daemon

排错日志

[root@bakcup ~]# tail /var/log/rsyncd.log
