rsync+inotify 备份

一，服务端安装（备份服务器）：

#安装rsync
cd /usr/local/src/
wget http://rsync.samba.org/ftp/rsync/src/rsync-3.0.9.tar.gz
tar zxvf rsync-3.0..tar.gz
cd rsync-3.0.
./configure --prefix=/usr/local/rsync
make && make install

#新建用户与密码认证文件
echo "backup:backup" > /usr/local/rsync/rsyncd.passwd
chmod  /usr/local/rsync/rsyncd.passwd

#新建rsync配置文件
cat > /usr/local/rsync/rsyncd.conf  <<EOF
uid = root
gid = root
use chroot = no
max connections =
strict modes = yes
hosts allow = 192.168.1.101 #可以空格，允许多个
port =
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsync.lock
log file = /var/log/rsyncd.log

[test]
#当前服务器要同步到此的目录(/home/jerome/test )
path = /home/jerome
ignore errors
read only = false
list = false
auth users = backup
secrets file = /usr/local/rsync/rsyncd.passwd
#PS：注意这里要将read only 修改为 false, 因为是要将文件同步到该模块的，必须可写

EOF

#以守护进程方式启动rsync服务器
rsync --daemon --config=/usr/local/rsync/rsyncd.conf

#我们可以把rsync脚本加入到开机启动项里
echo "/usr/local/rsync/bin/rsync --daemon --config=/usr/local/rsync/rsyncd.conf" >> /etc/rc.local

二，检查rsync 是否正常启动：

[root@localhost rsync]# netstat -tnlp | grep
tcp               0.0.0.0:             0.0.0.0:*               LISTEN      /rsync
tcp6              :::                  :::*                    LISTEN      /rsync 

三，客户端安装（源服务器）

#安装rsync
cd /usr/local/src/
wget http://rsync.samba.org/ftp/rsync/src/rsync-3.0.9.tar.gz
tar zxvf rsync-3.0..tar.gz
cd rsync-3.0.
./configure --prefix=/usr/local/rsync
make && make install
echo "backup" > /usr/local/rsync/rsync.passwd
chmod  /usr/local/rsync/rsync.passwd
#安装inotify
yum install inotify-tools -y

四，同步脚本

#!/bin/bash
host=192.168.1.102 #server的ip(备份服务器)
src=/home/test/ #server端要实时监控的目录（/home/test），des是认证的模块名，需要与client的des一致
des=test
user=backup

inotifywait -mrq --timefmt '%d/%m/%y %H:%M' --format '%T %w%f%e' -e modify,delete,create,attrib $src | while read files
do
　　/usr/bin/rsync -vzrtopg --progress --password-file=/usr/local/rsync/rsync.passwd $src $user@$host::$des
　　echo "${files} was rsynced" >>/data/logs/rsync.log >&
done

运行：

sh /usr/local/rsync/inotify_rsync.sh &
