实验环境：
OS：RHEL5.6
主机1(client)： apache ip : 192.168.18.254
需要安装软件：sersync2+ rsync（默认已安装）
主机2(server)： rsync ip : 192.168.18.146
需要安装软件：rsync (默认已安装)
一、主机1的操作(1)
apache 192.168.18.254
[root@apache ~]#tar fvxz sersync.tar.gz #解压缩
GNU-Linux-x86/
GNU-Linux-x86/sersync2
GNU-Linux-x86/confxml.xml
[root@apache~]#cd GNU-Linux-x86/
[root@apacheGNU-Linux-x86]#vim confxml.xml #修改sersync的配置文件
<sersync>
<localpath watch="/var/www/html"> #同步本地目录的路径
<remote ip="192.168.18.146"name="www"/> #远端服务器的ip和共享目录的名称
<commonParamsparams="-artuz"/>
<auth start="true" users="lijie"passwordfile="/etc/rsync.pass"/> #用户名与密码文件存放路径
<failLog path="/tmp/rsync_fail_log"timeToExecute="60"/><!--default every 60mins
execute once-->;
二、主机2的操作
rsync192.168.18.146
[root@rsync ~]#mkdir –pv /e tc/rsyncd #创建rsync配置文件的目录
[root@rsync ~]#cd /etc/rsyncd
[root@rsync rsyncd]#vim rsyncd.secrets #添加用户验证信息
lijie:123
[root@rsyncrsyncd]#chmod 600 /etc/rsyncd rsyncd.secrets #注意，此文件的权限必须是600
[root@rsyncrsyncd]#ll /etc/rsyncd rsyncd.secrets
rw------- 1 root root 13 Jul 14 02:20 rsyncd.secrets
[root@rsync rsyncd]#vim/etc/rsyncd/rsyncd.conf #编辑rsync的主配置文件
uid=root
gid=root
port=873
maxconnections=0 #limit client conection
use chroot = no
log file=/var/log/rsyncd.log
pid file=/var/run/rsyncd.pid
lock file=/var/run/rsyncd.lock
motd file = /etc/rsyncd/rsyncd.motd
read only=no #关闭只读，因为主机1要向主机2 共享目录中执行写的操作
####limit user conn######
hosts allow=192.168.18.0/255.255.255.0
hosts deny=*
#transfer logging = yes
#log format = %t%a %m %f %b
#syslog facility = local3
#timeout = 300
[www] #共享目录名称

ignore errors
auth users = lijie #定义用户
###username!!
secrets file = /etc/rsyncd/rsyncd.secrets #用户验证机制存放路径
comment = www directory #描述
read only = no
[root@rsync rsyncd]#mkdir –p /tmp/www #创建共享目录
[root@rsync ~]##rsync --daemon--config=/etc/rsyncd/rsyncd.conf #启动rsyns
146#lsof -i:873 #验证启动结果
COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME
rsync 4356 root 4u IPv6 14561 TCP *:rsync (LISTEN)
rsync 4356 root 5u IPv4 14562 TCP *:rsync (LISTEN)
三、主机1的操作(2)
apache192.168.18.254
[root@apache~]#vim /etc/rsyns.pass #编辑密码文件
123
[root@apache ~]#chmod 600 /etc/rsync.pass #密码文件权限为600
[root@apache ~]#ps axu | grep rsync #查看本机是否启动rsync进程，有--> kill掉，
root 8043 0.0 0.0 5252 480 ? Ss 11:08 0:00 rsync --daemon --config=/etc/rsyncd/rsyncd.conf
root 8191 0.6 2.3 82416 24024 pts/7 S+ 11:17 0:11 gedit rsync.txt
root 8668 0.0 0.0 5024 696 pts/3 S+ 11:46 0:00 grep rsync
[root@apache ~]# kill -9 8043 #kill rsync进程
Test 启动测试
[root@apache~]#cd GNU-Linux-x86/
[root@apacheGNU-Linux-x86]# ./sersync2 -r #启动sersync服务
set the systemparam
execute：echo50000000 > /proc/sys/fs/inotify/max_user_watches
execute：echo327679 > /proc/sys/fs/inotify/max_queued_events
parse the command param
option: -r rsync all the local files to the remoteservers before the sersync work
daemon thread num: 10
parse xml config file
host ip : localhost host port: 8008
use rsync password-file :
user is lijie
passwordfile is /etc/rsync.pass
config xml parse success
please set /etc/rsyncd.conf maxconnections=0 Manually
sersync working thread 12 = 1(primary thread) + 1(fail retry thread) +10(daemon sub threads)
Max threads numbers is: 22 = 12(Thread poolnums) + 10(Sub threads)
please according your cpu ，use -n param to adjust the cpu rate
------------------------------------------
rsync the directory recursivly to theremote servers once
working please wait...
execute command: cd /var/www/html&& rsync -artuz -R --delete ./ lijie@192.168.19.40::www--password-file=/etc/rsync.pass >/dev/null 2>&1
run the sersync:
watch path is: /var/www/html
此终端已被占用，如果需要进行测试同步结果，就需要另开一个终端，本实验就不在测试啦！
