rsync + inotify

rsync的客户端向服务端发送文件，发送文件到服务端::backup_8_114这个模块下，但是发送不出去

[root@localhost opt]#  rsync --delete -avz /opt/dojsa rsync_backup@192.168.8.109::backup_8_114 --password-file=/etc/rsync.password

sending incremental file list

ERROR: module is read only

rsync error: syntax or usage error (code 1) at main.c(1142) [Receiver=3.2.3]

配置文件rsync服务端如下：

[root@localhost ~]# cat /etc/rsyncd.conf 
#rsync_config_______________start
#created by   jin 01:23 2019-06-09
#Email:3128743705@qq.com 
##rsyncd.conf start##
uid = rsync
gid = rsync
use chroot = no
max connections = 200
timeout = 300
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsync.lock
log file = /var/log/rsyncd.log #这个是 rsync 的 log 文件，比较有用
[backup]
path = /backup/
ignore errors
read only = false
list = false
hosts allow = 192.168.8.0/24
hosts deny = 0.0.0.0/32
auth users = rsync_backup
secrets file = /etc/rsyncd/rsync.password

[backup_8_114]
path = /backup/192.168.8.114

#rsync_config_______________end
————————————————

解决方案：

上次文章中的配置文件中加read only = false

[root@localhost 192.168.8.114]# cat /etc/rsyncd.conf

#rsync_config_______________start

#created by jin 01:23 2019-06-09

#Email:3128743705@qq.com

##rsyncd.conf start##

uid = rsync

gid = rsync

use chroot = no

max connections = 200

timeout = 300

pid file = /var/run/rsyncd.pid

lock file = /var/run/rsync.lock

log file = /var/log/rsyncd.log #这个是 rsync 的 log 文件，比较有用

[backup]

path = /backup/

ignore errors

read only = false

list = false

hosts allow = 192.168.8.0/24

hosts deny = 0.0.0.0/32

auth users = rsync_backup

secrets file = /etc/rsyncd/rsync.password

[backup_8_114]

path = /backup/192.168.8.114

read only = false

#rsync_config_______________end

[root@localhost ~]# rsync --delete -avz /opt/ rsync_backup@192.168.8.109::backup_8_114 --password-file=/etc/rsync.password

在客户端下载inotify并写脚本

[root@localhost ~]# cat /etc/rsync.sh 
#!/bin/bash
/usr/bin/inotifywait -mrq --format '%w%f' -e create,close_write,delete /root/ |while read file
 do
cd /root/ && rsync -az --delete /root/
 rsync_backup@192.168.8.xxx::backup_8_114 --password-file=/etc/rsync.password 
done

测试：

rsync客户端在/root目录下创建文件

在服务端在这个模块下backup_8_114查看新增文件
