移动配置文件rsyncd.conf

创建密码文件

root@iZ25kq9nx52Z:~# vim /etc/rsyncd.secrets

yanfa_rsync:fromyanfa

给密码文件赋予权限

root@iZ25kq9nx52Z:~# chmod 0600 /etc/rsyncd.secrets

查看权限:

root@iZ25kq9nx52Z:~# ll /etc/rsyncd.secrets

-rw------- 1 root root 22 Mar 13 14:49 /etc/rsyncd.secrets

启动rsync

root@iZ25kq9nx52Z:~# /etc/init.d/rsync start

[....] Starting rsync (via systemctl): rsync.service.

查看是否启动服务:

root@iZ25kq9nx52Z:~# ps -ef | grep rsync

root 2235 1 0 13:50 ? 00:00:00 /usr/bin/rsync --no-detach --daemon --config /etc/rsyncd.conf

root 2333 2017 0 14:51 pts/0 00:00:00 grep --color=auto rsync

Client端

创建密码文件

root@iZ2zejccb1trnt5m8yav32Z:~# vim /etc/rsync.pwd

fromyanfa

给密码文件赋予权限

root@iZ2zejccb1trnt5m8yav32Z:~# chmod 0600 /etc/rsync.pwd

root@iZ2zejccb1trnt5m8yav32Z:~# chown root:root /etc/rsync.pwd

(如果是非root用户,只能使用自己当前用户和自己所在的组)

查看权限:

root@iZ2zejccb1trnt5m8yav32Z:~# ll /etc/rsync.pwd

-rw------- 1 root root 10 Mar 13 14:54 /etc/rsync.pwd

添加定时任务

root@iZ2zejccb1trnt5m8yav32Z:~# crontab -e

Select an editor. To change later, run 'select-editor'.

1. /bin/ed

2. /bin/nano <---- easiest

3. /usr/bin/vim.basic

4. /usr/bin/vim.tiny

Choose 1-4 [2]: 3

第一次使用crontab时,会选择编辑器,选第三个vim

1. 客户端拉取moors新增的备份文件:

5 11 * * * rsync -avz --delete --password-file=/etc/rsync.pwd

yanfa_rsync@101.201.101.146::my_rsync_bk /mnt/uftp/file > /etc/msg.log 2>&1 &

2. 客户端拉取moors数据库新增的备份文件:

40 13 * * * rsync -avz --delete --password-file=/etc/rsync.pwd yanfa_rsync@101.201.101.146::my_rsync_mysql /usr/local/mysql-bak >/etc/msg2.log 2>&1 &

查询所有的定时器:

root@iZ2zejccb1trnt5m8yav32Z:~# crontab -l

# m h dom mon dow command

5 11 * * * rsync -avz --delete --password-file=/etc/rsync.pwd yanfa_rsync@101.201.101.146::my_rsync_bk /mnt/uftp/file >/etc/msg.log 2>&1 &

40 13 * * * rsync -avz --delete --password-file=/etc/rsync.pwd yanfa_rsync@101.201.101.146::my_rsync_mysql /usr/local/mysql-bak >/etc/msg2.log 2>&1 &

use chroot = yes #默认是yes,在rsync在传输文件以前首先chroot到path参数指定的目录下。这样做的原因是实现额外的安全防护,但是缺点是需要root权限,并且不能备份指向外部的符号连接指向的目录文件。

# max connections=10 #最大连接数

lock file = /var/lock/rsyncd #指定支持max connections参数的锁文件。

# the default for read only is yes...

# include = #与exclude相似

# include from = #可以指定一个包含include模式定义的文件名

# auth users = #该选项指定由空格或逗号分隔的用户名列表,只有这些用户才允许连接该模块。

# secrets file = /etc/rsyncd.secrets #该文件每行包含一个username:password对,以明文方式存储,只有在auth users被定义时,此选项才生效。同时我们需要将此文件权限设置为0600

strict modes = yes #该选项指定是否监测密码文件的权限,如果该选项值为true那么密码文件只能被rsync服务器运行身份的用户访问,其他任何用户不可以访问该文件。默认值为true

# hosts allow = #允许的主机

# hosts deny = #拒绝访问的主机

ignore errors = no #设定rsync服务器在运行delete操作时是否忽略I/O错误

ignore nonreadable = yes #设定rysnc服务器忽略那些没有访问文件权限的用户

# log format = %t: host %h (%a) %o %f (%l bytes). Total %b bytes. #设定日志格式

timeout = 600 #超时设置(秒)

refuse options = checksum dry-run #定义一些不允许客户对该模块使用的命令选项列表

dont compress = *.gz *.tgz *.zip *.z *.rpm *.deb *.iso *.bz2 *.tbz #告诉rysnc那些文件在传输前不用压缩,默认已设定压缩包不再进行压缩
