rsync + inotify 触发式同步
【基本介绍】
rsync :
rsync is a program that behaves in much the same way that rcp does, but has many more options and uses the rsync remote-update protocol to greatly speed up file transfers when the destination file is being updated.
inotify :
The inotify API provides a mechanism for monitoring file system events.Inotify can be used to monitor individual files, or to monitor directo-ries. When a directory is monitored, inotify will return events for the directory itself, and for files inside the directory.
rsync+inotify ,实现监控某个文件或目录,实现实时同步到远程地址。1->n的传输需求(1为客户端,n为服务端,客户端不需要配置rsync服务器,启动inotify监听脚本。服务端启动rsync daemon)
【rsync 安装配置】
rsync 安装---省略几百字
#touch /etc/rsyncd/rsyncd.conf #创建rsync服务器的配置文件;
#touch /etc/rsyncd/rsyncd.secrets 创建用户密码文件;
#chmod 600 /etc/rsyncd/rsyncd.secrets 我们把权限设为600;
rsyncd.conf:
uid=root
gid=nobody
max connections=200
timeout=600
use chroot=no
use chroot=no
read only=false
log file=/var/log/rsyncd.log
pid file=/var/log/rsyncd.pid
lock file=/var/log/rsync.lock
host_allow=xxxx (这个需要传输的服务器地址)
[app]
path=xxxx (这个就是传输的地址)
comment=xxx
list=yes
auth users=web
secrets file=/etc/rsyncd.secrets
rsyncd.secrets: (客户端与服务端一致,客户端不需要用户名)
web:@xxxxxxxxxxxxxxx@
【inotify】
inotify : 安装省略数百字
【rsync+inotify】
rsync.sh:
#!/bin/sh
src1=/xxxx #(监听的路径)
/usr/local/inotify/bin/inotifywait --exclude "xxx" -mrq -e create,move,delete,modify $src1 | while read file
do
rsync -zaq --delete --port=8730 --password-file=/etc/rsyncd.secrets --exclude=log/ $src1 web@xxxx::app #(每个客户端遍历一遍,app是定义的模块名)
rsync -zaq --delete --port=8730 --password-file=/etc/rsyncd.secrets --exclude=log/ $src1 web@xxxx::app
rsync -zaq --delete --port=8730 --password-file=/etc/rsyncd.secrets --exclude=log/ $src1 web@xxxx::app
done
在服务器端运行这个脚本即可实现实时同步。
【基本流程】
1.在服务器端/客户端安装rsync
2.在客户端安装inotify
3.配置服务端的rsync daemon或者rsync服务器监听
4.服务器端和客户端都设置rsyncd.secrets密码文件(客户端只需要密码,服务端用户名:密码)
4.在客户端端实现rsync+inotify脚本
