inotify+rsync安装配置

环境	系统	IP地址
主服务器	CentOS7.4	192.168.1.1
备份服务器	CentOS7.4	192.168.1.2

一、备份服务器

安装rsync(备)

wget https://rsync.samba.org/ftp/rsync/src/rsync-3.1.3.tar.gz
tar -xf rsync-3.1.3.tar.gz
./configure --prefix=/usr/local/rsync
make && make install

配置rsyncd.conf

cat <<EOF> /etc/rsyncd.conf
pid file = /var/run/rsync.pid
log file = /var/log/rsync.log
lock file=/var/run/rsync.lock
secrets file = /etc/rsync.pw
motd file = /etc/rsyncd.motd
transfer logging = yes
log format = %t %a %m %f %b
syslog facility = local3
[data]
path = /data/test/
comment = data
exclude =
port = 873
uid = root
gid = root
timeout = 600
max connections = 200
use chroot = no
read only = no
list = no
hosts allow = 192.168.1.1
EOF

可以设置多个目录

#增加test1目录
[test1]
path = /data/test1
list = yes
ignore errors
comment = ucweb-file system
secrets file = /etc/rsync.pw
exclude = blank.png ; spinner.gif ; downsimple.png ; rails.png ; WEB-INF/

建立密码认证文件

cat <<EOF> /etc/rsync.pw
root:123456
EOF

配置rsyncd.motd文件，开始传送的时候会显示

cat <<EOF> /etc/rsyncd.motd
###############################
#                             #
#        start rsync          #
#                             #
###############################
EOF

启动rsync

/usr/local/rsync/bin/rsync --daemon --config=/etc/rsyncd.conf

开机启动rsync

echo '/usr/local/rsync/bin/rsync --daemon --config=/etc/rsyncd.conf'>>/etc/rc.d/rc.localer 

二、主服务器

建立密码认证文件

cat <<EOF> /etc/rsync.pw
123456
EOF

测试开始

/usr/local/rsync/bin/rsync -avH --port=873 --progress --delete /data/test/ root@192.168.1.3::data --password-file=/etc/rsync.pw

查看192.168.1.2上是否有同步

安装inotify-tools

yum install inotify-tools -y

新建inotify.sh文件同步

#!/bin/sh
# get the current path
CURPATH=`pwd`
/usr/bin/inotifywait -mr --timefmt '%d/%m/%y %H:%M' --format '%T %w %f' -e modify /data | while read date time dir file; do
       FILECHANGE=${dir}${file}
       # convert absolute path to relative
       FILECHANGEREL=`echo "$FILECHANGE" | sed 's_'$CURPATH'/__'`  
 
       /usr/bin/rsync -avH --port=873 --progress --delete /data/test/ root@192.168.1.2::data --password-file=/etc/rsync.pw
       echo "At ${time} on ${date}, file $FILECHANGE was backed up via rsync"
done

注意：

如果仅仅是备份的话，不要带delete参数
