一、规划：
数据同步源： nfs-s1 IP:172.16.1.10 目录:/data/images
数据同步目的：nfs-s2 IP:172.16.1.20 目录:/data/images
二、配置步骤：
1、在 nfs-s2 配置 rsync daemon ,并启动。nfs-s1 配置 rsync client。
2、在 nfs-s1 配置 sersync 。
三、nfs-s2 配置 rsync daemon :（注意目录对于相应其他程序的读写权限）
[root@nfs-s2 ~]# ifconfig eth0|awk -F "[ :]+" "NR==2{print $4}"
172.16.1.20
[root@nfs-s2 ~]# uname -r
2.6.32-504.el6.x86_64
[root@nfs-s2 ~]#
[root@nfs-s2 ~]# useradd -s /sbin/nologin -M www
[root@nfs-s2 ~]# mkdir /data/images -p
[root@nfs-s2 ~]# chown -R www.www /data/images/
编辑 /etc/rsyncd.conf
[root@nfs-s2 ~]# cat /etc/rsyncd.conf
uid=www
gid=www
use chroot=true
read only=false
list=false
ignore errors=true
hosts allow=172.16.1.0/24
hosts deny=0.0.0.0/0
max connections=1000
pid file=/var/run/rsyncd.pid
lock file=/var/run/rsyncd.lock
log file=/var/log/rsyncd.log
auth users=sersync
secrets file=/etc/rsync.passwd
[images]
comment=images from nfs-s1
path=/data/images
[root@nfs-s2 ~]#
编辑 rsync daemon 用户密码文件 :
[root@nfs-s2 ~]# echo "sersync:123456">/etc/rsync.passwd
[root@nfs-s2 ~]# cat /etc/rsync.passwd
sersync:123456
[root@nfs-s2 ~]# chmod 700 /etc/rsync.passwd
启动 rsync daemon :
[root@nfs-s2 ~]# rsync --daemon
在 nfs-s1 创建 rsync daemon 密码文件 :
[root@nfs-s1 ~]# ifconfig eth0|awk -F "[ :]+" "NR==2{print $4}"
172.16.1.10
[root@nfs-s1 ~]# uname -r
2.6.32-504.el6.x86_64
[root@nfs-s1 ~]#
[root@nfs-s1 ~]# echo "123456">/etc/rsync.passwd
[root@nfs-s1 ~]# chmod 700 /etc/rsync.passwd
[root@nfs-s1 ~]#
测试 :
[root@nfs-s1 ~]# echo "test rsync daemon from nfs-s1">rsync.test
[root@nfs-s1 ~]# rsync -avz rsync.test sersync@172.16.1.20::images --password-file /etc/rsync.passwd
sending incremental file list
rsync.test
sent 68 bytes received 33 bytes 40.40 bytes/sec
total size is 30 speedup is 0.30
[root@nfs-s1 ~]#
rsync daemon 配置成功。
[root@nfs-s2 ~]# echo "rsync --daemon">>/etc/rc.local
[root@nfs-s2 ~]# tail -1 /etc/rc.local
rsync --daemon
[root@nfs-s2 ~]#
四、在 nfs-s1 安装配置 sersync :(目录权限根据实际情况设置)
[root@nfs-s1 ~]# useradd -s /sbin/nologin -M www
[root@nfs-s1 ~]# mkdir -p /data/images
[root@nfs-s1 ~]# chown -R www.www /data/images/
[root@nfs-s1 ~]#
下载 sersync :
[root@nfs-s1 src]# wget -q http://www.z-dig.com/repos/sersync2.5.4_64bit_binary_stable_final.tar.gz
[root@nfs-s1 src]# ls
sersync2.5.4_64bit_binary_stable_final.tar.gz
[root@nfs-s1 src]# tar xf sersync2.5.4_64bit_binary_stable_final.tar.gz
[root@nfs-s1 src]# ls
GNU-Linux-x86 sersync2.5.4_64bit_binary_stable_final.tar.gz
[root@nfs-s1 src]#
[root@nfs-s1 src]# mv GNU-Linux-x86 /usr/local/sersync
[root@nfs-s1 src]# cd /usr/local/sersync/
[root@nfs-s1 sersync]# ls
confxml.xml sersync2
[root@nfs-s1 sersync]# mkdir {bin,conf,log}
[root@nfs-s1 sersync]# ls
bin conf confxml.xml log sersync2
[root@nfs-s1 sersync]# mv confxml.xml conf
[root@nfs-s1 sersync]# mv sersync2 bin/sersync
[root@nfs-s1 sersync]# tree .
.
├── bin
│ └── sersync
├── conf
│ └── confxml.xml
└── log
3 directories, 2 files
[root@nfs-s1 sersync]#
编辑 confxml.xml :（可根据实际需求进行细粒度的配置）
[root@nfs-s1 sersync]# cat conf/confxml.xml
[root@nfs-s1 sersync]#
启动 sersync :
[root@nfs-s1 sersync]# /usr/local/sersync/bin/sersync -r -d -o /usr/local/sersync/conf/confxml.xml
set the system param
execute：echo 50000000 > /proc/sys/fs/inotify/max_user_watches
execute：echo 327679 > /proc/sys/fs/inotify/max_queued_events
parse the command param
option: -r rsync all the local files to the remote servers before the sersync work
option: -d run as a daemon
option: -o config xml name： /usr/local/sersync/conf/confxml.xml
daemon thread num: 10
parse xml config file
host ip : localhost host port: 8008
daemon start，sersync run behind the console
use rsync password-file :
user is sersync
passwordfile is /etc/rsync.passwd
config xml parse success
please set /etc/rsyncd.conf max connections=0 Manually
sersync working thread 12 = 1(primary thread) + 1(fail retry thread) + 10(daemon sub threads)
Max threads numbers is: 22 = 12(Thread pool nums) + 10(Sub threads)
please according your cpu ，use -n param to adjust the cpu rate
------------------------------------------
rsync the directory recursivly to the remote servers once
working please wait...
execute command: cd /data/images && rsync -artuz -R --delete ./ sersync@172.16.1.20::images --password-file=/etc/rsync.passwd >/dev/null 2>&1
run the sersync:
watch path is: /data/images
[root@nfs-s1 sersync]#
测试 :
[root@nfs-s1 sersync]# touch /data/images/{1..100}.png
[root@nfs-s2 ~]# ls /data/images/
