环境：web1:10.80.11.243web2:10.80.11.244code:10.80.11.245更新code服务器的代码后，自动同步到web1和web2,删除code服务器文件，web1和web2也删除服务器端的安装（N台WEB都这样配置）1、首先要求Linux内核在2.6以上，才支持<span verdana','sans-serif'"="" style="padding: 0px;font-size: 13px;color: black">inotify[root@web1 html]# uname -aLinux web1 2.6.18-194.el5 #1 SMP Fri Apr 2 14:58:35 EDT 2010 i686 i686 i386 GNU/Linux2、检查是否安装rsync软件[root@web1 html]# rpm -qa |grep rsyncrsync-2.6.8-3.1如果没有的话，通过yum –y install rsync安装3、新建rsync配置文件，该软件安装默认没有配置文件#vim /etc/rsyncd.confmotd file = /etc/rsyncd.motduid=rootgid=rootmax connections=36000use chroot=nolog file=/var/log/rsyncd.loglog format = %t %a %m %f %bpid file=/var/run/rsyncd.pidlock file=/var/run/rsyncd.locktimeout = 300 [tongbu]path=/var/www/htmllist=yescomment = this is commentignore errors = yesread only = nohosts allow = 10.80.11.245hosts deny = *auth users backupsecrets file = /etc/rsyncd.secrets
注：tongbu为发布模块，相当于路径的别名hosts allow是只允许连接的IPsecrets file = /etc/rsyncd.secrets这是密码文件，同步的用户为backup，下面创建同步用户#useradd backup#passwd backup#vim /etc/rsyncd.secretsbackup:123456格式为用户名：密码#chmod 600 /etc/rsyncd.secrets设置只有root用户才能查看这个文件4、启动服务/usr/bin/rsync --daemon --config=/etc/rsyncd.conf其他的WEB服务器配置和上面是一样的。如果需要开机启动，加入到/etc/rc.local发布端的配置1、发布端主要利用开源软件sersync，网站为：http://code.google.com/p/sersync/#cd /usr/local/#wget http://sersync.googlecode.com/files/sersync2.5RC1_32bit_binary.tar.gz#tar –zxvf sersync2.5RC1_32bit_binary.tar.gz#cd GNU-Linux-x862、修改配置文件#vim confxml.xml<?xml version="1.0" encoding="ISO-8859-1"?><head version="2.5"> <host hostip="localhost" port="8008"></host> <filter start="false"> <exclude expression="(.*)\.gz"></exclude> <exclude expression="^info/*"></exclude> </filter> <inotify> <delete start="true"/> <create start="true"/> </inotify> <debug start="false"/> <sersync> <localpath watch="/var/www/html"> <remote ip="10.80.11.243" name="tongbu"/> <remote ip="10.80.11.244" name="tongbu"/> </localpath> <rsync> <auth start="true" users="backup" passwordfile="/etc/rsync.pas"/> <userDefinedPort start="false" port="874"/><!-- port=874 --> <timeout start="false" time="100"/><!-- timeout=100 --> <ssh start="false"/> </rsync> <failLog path="/tmp/rsync_fail_log.sh" timeToExecute="60"/><!--default every 60min execute once--> <crontab start="false" schedule="600"><!--600mins--> <crontabfilter start="false"> <exclude expression="*.php"></exclude> <exclude expression="info/*"></exclude> </crontabfilter> </crontab> <plugin start="false" name="command"/> </sersync> <plugin name="command"> <param prefix="/bin/sh" suffix="" ignoreError="true"/> <!--prefix /opt/tongbu/mmm.sh suffix--> <filter start="false"> <include expression="(.*)\.php"/> <include expression="(.*)\.sh"/> </filter> </plugin> <plugin name="socket"> <localpath watch="/opt/tongbu"> <deshost ip="192.168.138.20" port="8009"/> </localpath> </plugin> <plugin name="refreshCDN"> <localpath watch="/data0/htdocs/cms.xoyo.com/site/"> <cdninfo domainname="ccms.chinacache.com" port="80" username="xxxx" passwd="xxxx"/> <sendurl base="http://pic.xoyo.com/cms"/> <regexurl regex="false" match="cms.xoyo.com/site([/a-zA-Z0-9]*).xoyo.com/p_w_picpaths"/> </localpath> </plugin> </head>/var/www/html为发布服务器的源码发布目录主要修改红色标记部分，密码文件为/etc/rsync.pas#vim /etc/rsync.pas
123456#解释：123456代表的是Rsync server端的密码，并且要以"#"做结尾。如果有多个密码，增加多行就行。#chmod 600 /etc/rsync.pas3、启动服务#<span verdana','sans-serif'"="" style="padding: 0px;font-size: 13px;color: black">./sersync2 -d –r这种方式常驻进程，如果需要开机启动，加入到<span verdana','sans-serif'"="" style="padding: 0px;font-size: 13px;color: black">/etc/rc.local这样只要修改发布服务器/var/www/html的文件，web服务器就会自动同步。
