sersync2 实时同步配置
自动同步文件或者是目录
实现的方式：
在同步服务器上开启sersync，将监控路径中的文件同步到目标服务器，因此需要在同步服务器配置sersync，在同步目标服务器配置rsync
实验机器的地址分配：
Rsync 服务器： 192.168.1.112
Sersync2 服务器：192.168.1.110
系统环境
[root@liyao home]# uname -a
Linux liyao 2.6.18-194.el5 #1 SMP Fri Apr 2 14:58:35 EDT 2010 i686 i686 i386 GNU/Linux
[root@liyao home]#
一、 rsync 服务器的配置
1. 先查看下是否安装了 rsync 软件包
[root@liyao ~]# rpm -qa | grep rsync
rsync-2.6.8-3.1
[root@liyao ~]#
2. 如果系统默认安装了 rsync 软件包，我们可以使用 yum 命令将其卸载
[root@liyao ~]# yum remove -y rsync
Loaded plugins: fastestmirror

[root@liyao ~]#
3. 下载 rsync 3.0 的源码包
[root@liyao~]#wget-chttp://rsync.samba.org/ftp/rsync/rsync-3.0.8.tar.gz
--2011-08-20 08:05:05-- http://rsync.samba.org/ftp/rsync/rsync-3.0.8.tar.gz Resolving rsync.samba.org... 216.83.154.106, 2001:470:1f05:1a07::1

2011-08-20 08:05:11 (135 KB/s) - `rsync-3.0.8.tar.gz' saved [790722/790722]
4. 将该软件包解压缩，并且进行编译安装
[root@liyao ~]# tar zxf rsync-3.0.8.tar.gz
[root@liyao ~]# cd rsync-3.0.8
[root@liyao rsync-3.0.8]# ./configure --prefix=/usr/ && make && make install
5. 建立 rsync 服务器的配置文件
uid = nobody
gid = nobody
use chroot = no
strict modes = yes
max connections = 200
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsync.lock
log file = /var/log/rsyncd.log
[test]
path = /home/
comment = test
read only = no
write only = no
ignore errors = yes
list = yes
uid = root
gid = root
6. 启动 rsync 的服务
[root@liyao ~]# rsync --daemon
[root@liyao ~]# netstat -npl | grep 873
tcp 0 0 0.0.0.0:873 0.0.0.0:* LISTEN 7731/rsync
tcp 0 0 :::873 :::* LISTEN 7731/rsync
二、 配置Sersync2 服务器
二进制直接可运行
wget http://sersync.googlecode.com/files/sersync2.5_64bit_binary_stable_final.tar.gz
http://sersync.googlecode.com/files/sersync2.5_32bit_binary_stable_final.tar.gz
1、将该软件包下载下来之后解压缩，并进行安装
[root@liyao ~]# tar zxf sersync2.5_32bit_binary_stable_final.tar.gz
[root@liyao ~]# ls
anaconda-ks.cfg install.log.syslog
GNU-Linux-x86 sersync2.5_32bit_binary_stable_final.tar.gz
install.log
[root@liyao ~]# cd GNU-Linux-x86/
[root@liyao GNU-Linux-x86]# ls
confxml.xml sersync2
[root@liyao GNU-Linux-x86]# mkdir /etc/sersync2
[root@liyao GNU-Linux-x86]# cp confxml.xml /etc/sersync2/
[root@liyao GNU-Linux-x86]# cp sersync2 /usr/bin/
# 安装该软件只要把软件中的文件拷贝到相应的目录即可
2. 修改 Sersync2 的配置文件
[root@liyao ~]# cat /etc/sersync2/confxml.xml
<?xml version="1.0" encoding="ISO-8859-1"?>

[root@liyao ~]#
3. 我们来运行如下的备份命令
在运行备份命令之前我们先看下 /home 这个目录下面有文件或者是目录
[root@liyao home]# ls -l
total 4
drwxr-xr-x 2 root root 4096 Aug 20 08:51 liyao
[root@liyao home]#
[root@liyao ~]# sersync2 -r -d -o /etc/sersync2/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： /etc/sersync2/confxml.xml
daemon thread num: 10
parse xml config file
host ip : localhost host port: 8008
daemon start，sersync run behind the console
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 /home && rsync -artuz -R --delete ./ 192.168.1.112::test >/dev/null 2>&1
run the sersync:
watch path is: /home
4. 我们到 rsyncd 服务器（1.112）的 /home 目录下看看是否有我在 1.110 /home/liyao 这个目录
[root@liyao home]# ls
liyao
[root@liyao home]#
那我们在从 1.110 的 /home 目录下创建 abc 目录，不用执行任何命令他会自动同步到 1.112 上
[root@liyao home]# mkdir abc
[root@liyao home]# ls
abc liyao
[root@liyao home]#
我们在去 1.112 上去看下，abc 目录已经同步过来了
[root@liyao home]# ll
total 8
drwxr-xr-x 2 root root 4096 Aug 21 04:12 abc
drwxr-xr-x 2 root root 4096 Aug 21 04:05 liyao
[root@liyao home]#
OK ，这样我们就大功告成了。
