安装

server和client端都需要安装rsync，只不过client端不需要配置：

# apt install rsync

2、配置server端的/etc/rsyncd.conf文件

拷贝示例配置文件到/etc目录

#  cp /usr/share/doc/rsync/examples/rsyncd.conf /etc/

查看rsyncd.conf文件，按需要修改即可

# more /etc/rsyncd.conf

# sample rsyncd.conf configuration file

# GLOBAL OPTIONS

#motd file=/etc/motd

log file=/var/log/rsyncd.log

# for pid file, do not use /var/run/rsync.pid if

# you are going to run rsync out of the init.d script.

pid file=/var/run/rsyncd.pid

#syslog facility=daemon

#socket options=

# MODULE OPTIONS

[www]               # 这里是认证的模块名，在client端需要指定

        comment = source high app archive

        path = /data/webroot/rsynctest  # 需要同步的目录

        use chroot = yes

#       max connections=10

        lock file = /var/lock/rsyncd

# the default for read only is yes...

        read only = no

        list = yes

        uid = www-data

        gid = www-data

#       exclude =

#       exclude from =

#       include =

#       include from =

        auth users = appbackup  # 认证的用户名，如果没有这行，则表明是匿名

        secrets file = /etc/rsyncd.secrets  # 认证密码文件

        strict modes = yes

    #    hosts allow = 192.168.206.200 #充许任何主机连接

#       hosts deny =

        ignore errors = no  # 可以忽略一些无关的IO错误

        ignore nonreadable = yes

        transfer logging = yes

#       log format = %t: host %h (%a) %o %f (%l bytes). Total %b bytes.

        timeout = 600

        refuse options = checksum dry-run

        dont compress = *.gz *.tgz *.zip *.z *.rpm *.deb *.iso *.bz2 *.tbz

3、在server端创建密码文件/etc/rsyncd.secrets，权限必须是0600

# nano /etc/rsyncd.secrets

    username:password

    user:123456

 #chmod 600 /etc/rsyncd.secrets

4、设置rsync 开机启动

    systemctl enable rsync
