# /etc/rsyncd: configuration file for rsync daemon mode
port873
log file/var/log/rsync.log
pid file/var/run/rsyncd.pid
address192.168.193.128
# See rsyncd.conf man page for more options.# configuration example:
[test]
path/root/rsync
read onlyno
listtrue
uid root
gid root
use chroottrue
max connections4
auth userstest
secrets file/etc/rsyncd.passwd
hosts allow192.168.193.128rscond.com中的port,logfile,pid file,address都属于全局配置[test]以下的部分就是模块配置。man rsyncd.conf可以获得更多信息。port:指定在哪个端口启动rsyncd服务默认是873端口。log file:指定日志文件。pid file指定pid文件这个文件的作用涉及服务的启动、停止等进程管理操作。address指定启动rsyncd服务的IP。[]:指定模块名。path:指定数据存放的路径。use chroot true|false:表示在传输文件之前首先chroot到path参数所指定的目录下。max connections:指定最大的连接数默认是0即没有限制。read only ture|false:如果为true则不能上传到该模块指定的路径下。list表示当用户查询该服务器上的可用模块时该模块是否被列出设定为true则列出设定为false则隐藏。uid/gid:指定传输文件时以哪个用户/组的身份传输。auth users指定传输时要使用的用户名。secrets file指定密码文件。hosts allow:表示被允许连接该模块的主机。编辑secrets file并保存后要赋予600权限。[rootaminglinux-123 etc]# cat /etc/rsyncd.passwd
[rootaminglinux-123 etc]# vim /etc/rsyncd.passwd
[rootaminglinux-123 etc]# cat /etc/rsyncd.passwd

# see man logrotate for details
# rotate log files weekly
weekly# keep 4 weeks worth of backlogs
