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
