192.168.30.178   目标服务器(相当于备份服务器)

192.168.30.160 源服务器

一、目标服务器(192.168.30.178)上的设置:

开启防火墙tcp873rsync默认的端口

vim /etc/sysconfig/iptables 

-A INPUT -m state --state NEW -m tcp -p tcp --dport 873 -j ACCEPT

service iptables restart

安装rsync软件:

yum install rsync xinetd -y

vim /etc/xinetd.d/rsync #####设置开机自启动 把disable=yes ,改成no

# default: off

# description: The rsync server is a good addition to an ftp server, as it \

#       allows crc checksumming etc.

service rsync

{

        disable = no

        flags           = IPv6

        socket_type     = stream

        wait            = no

        user            = root

        server          = /usr/bin/rsync

        server_args     = --daemon

        log_on_failure  += USERID

}

添加新用户和组并赋给相应的权限:

groupadd rsync

useradd rsync 

mkdir /home/rsync/backup/

chown rsync:rsync /homersync/backup/

创建rsync daemon的配置文件

vim /etc/rsyncd.conf

=================================================

uid = rsync ||

gid = rsync ||

use chroot = no ||

max connections = 40 ||

timeout = 300 ||

pid file = /var/run/rsyncd.pid ||

lock file = /var/run/rsyncd.lock ||

log file = /home/rsync/backup/rsyncd.log ||

[backup] ||

path = /home/rsync/backup/ ||

ignore errors ||

read only = false ||

list = false ||

hosts allow = 192.168.30.0/24 ||

auth users = rsync ||

secrets file =/etc/rsync.password ||

====================================

创建密码文件

[root@GJB-UAT ~]# vim /etc/rsync.password

====================

rsync:vhost$1 ||

====================

启动xinted服务

/etc/init.d/xinted start

[root@GJB-UAT ~]# chmod 600 /etc/rsync.password 

[root@GJB-UAT ~]# chmod 600 /etc/rsyncd.conf

二、源服务器(192.168.30.160)安装rsync和inotify(监听作用)

开启防火墙tcp873rsync默认的端口

vim /etc/sysconfig/iptables 

-A INPUT -m state --state NEW -m tcp -p tcp --dport 873 -j ACCEPT

service iptables restart

安装rsync软件:

yum install rsync xinetd -y

vim /etc/xinetd.d/rsync #####设置开机自启动 把disable=yes ,改成no

============================================

# default: off

# description: The rsync server is a good addition to an ftp server, as it \

#       allows crc checksumming etc.

service rsync

{

        disable = no

        flags           = IPv6

        socket_type     = stream

        wait            = no

        user            = root

        server          = /usr/bin/rsync

        server_args     = --daemon

        log_on_failure  += USERID

}

=====================================

启动xinted服务

/etc/init.d/xinetd start

正在启动 xinetd:                                          [确定]

查看监听端口:

netstat -lntp|grep xinetd

tcp        0      0 :::873                      :::*                        LISTEN      38518/xinetd

创建认证文件

vim /etc/rsyncd.passwd 

vhost$1

[root@Monitor conf]# chmod 600 /etc/rsyncd.passwd

此步骤测试rsync能否正常使用:

rsync -avH --port=873 --progress /www/ rsync@192.168.30.178::backup --password-file=/etc/rsyncd.passwd

三、安装Inotify-tools工具,实时出发rsync进行同步

安装依赖的包

yum install make  gcc gcc-c++ 

下载inotify-tools软件包,此处官方打不开,使用的包是inotify-tools-3.14.tar

编译安装:

tar zxvf inotify-tools-3.14.tar

cd inotify-tools-3.14

./configure --prefix=/usr/local//inotify

make && make install
