10.245.6.54 主 10.245.6.53从1 10.245.6.52 从2 想实时同步54/eshop/eshopres/目录下的文件或目录 1、检测分发服务器系统是否满足需求，要求内核大于2.3 uname -r #查看系统内核 ll /proc/sys/fs/inotify/ 如图则满足需求。 2、在分发服务器下载最新版并编译安装 54需要安装： inotify-tools-3.14.tar.gz cd #回到用户目录 wget http://github.com/downloads/rvoicilas/inotify-tools/inotify-tools-3.14.tar.gz #下载最新版 tar zxvf inotify-tools-3.14.tar.gz #解压到当前目录 cd inotify-tools-3.14 #进入目录 ./configure --prefix=/alidata/server/inotify/ #编译配置，这里是指定位置（你的文件目录） make #编译 make install #安装 make clean #从源文件夹清除二进制对象等 cd /alidata/server/inotify/bin ./inotifywait --help #查看是否安装完成一般有错误上面几个步骤会有提示 ./inotifywait -mrq --format \'%Xe %w%f\' -e modify,create,delete,attrib /alidata/tmp/ #m是开启监测,r递归目录,/alidata/tmp监测的目录 touch /alidata/tmp/test1 #新开个tty创建个文件会有如下图输出<br><br> #为方便使用可以选择设置 #设置系统环境变量，添加软连接 #echo "PATH=$PATH:/alidata/server/inotify/bin" >>/etc/profile.d/inotify.sh #source /etc/profile.d/inotify.sh #使设置立即生效 #echo "/alidata/server/inotify/lib" >/etc/ld.so.conf.d/inotify.conf && ldconfig #ln -s /alidata/server/inotify/include /usr/include/inotify 正式配置： #!/bin/bash SRCDIR=/eshop/eshopres/ USER=backup DESTDIR=eshopres excludedir=/usr/local/inotify/exclude.list rsyncpass=/eshop/rsync/rsyncd.passwd dstip="10.245.6.53 10.245.6.52" dstip1=10.245.6.53 dstip2=10.245.6.52 datelog=`date -d today +"%Y-%m-%d"` dirpath = \\eshop\\rsync\\ filelogName=${dirpath}sync${datelog}.log echo ${filelogName} echo "the file name is $filelogName" if [ ! -f $filelogName ];then touch $filelogName echo ${filelogName}\' create ok.\' else echo file exist fi /alidata/server/inotify/bin/inotifywait -mrq --timefmt \'%d/%m/%y %H:%M\' --format \'%T %w%f%e\' -e close_write,modify,delete,create,attrib,move $SRCDIR | while read file do for ip in $dstip do /eshop/rsync/bin/rsync -avH --port=873 --progress --delete-before --exclude-from=$excludedir $SRCDIR $USER@$ip::$DESTDIR --password-file=$rsyncpass #echo " ${file} was rsynced " >> /eshop/rsync/rsync.log 2>&1 #/eshop/rsync/bin/rsync -avH --port=873 --progress --delete-before --exclude-from=$excludedir $SRCDIR $USER@$dstip1::$DESTDIR --password-file=$rsyncpass & #/eshop/rsync/bin/rsync -avH --port=873 --progress --delete-before --exclude-from=$excludedir $SRCDIR $USER@$dstip2::$DESTDIR --password-file=$rsyncpass #echo " ${file} was rsynced " >> /eshop/rsync/rsync.log 2>&1 echo " ${file} was rsynced " >> $filelogName 2>&1 done done 至此已经可以检测到分发服务器文件改动了。 在对一个大磁盘进行inotify监听时，爆出如下错误： Failed to watch /mnt/; upper limit on inotify watches reached! Please increase the amount of inotify watches allowed per user via `/proc/sys/fs/inotify/max_user_watches’. cat一下这个文件，默认值是8192， echo 8192000 > /proc/sys/fs/inotify/max_user_watches 即可~ 3、编译安装rsync到内容分发服务器在这里充当客户端的角色 rsync-3.1.3.tar.gz wget https://download.samba.org/pub/rsync/src/rs tar zxvf rsync-3.1.2.tar.gz cd rsync-3.1.2 ./configure --prefix=/alidata/server/rsync ./configure --prefix=/eshop/rsync make make install 接下来就是文件同步，检测到文件变动后主动向目标服务器推送，详情后面说。 4、编译安装rsync到目标服务器并启用服务 添加主配置文件： vim /etc/rsyncd.conf uid = root gid = root port = 873 use chroot = no hosts allow = * max connections = 3 motd file = /alidata/passwd/rsync/rsyncd.motd #问候语 pid file = /alidata/server/rsync/rsyncd.pid lock file = /alidata/server/rsync/rsync.lock log file = /alidata/log/rsync/rsyncd.log transfer logging = yes #传输日志 ignore errors #忽略错误 [netho] path = /alidata/tmp/rsynctest #同步路径 auth users = netho #使用用户必须是服务器真实用户 secrets file = /alidata/passwd/rsync/rsyncd.pass #用户认证文件 list = no read only = no #只读 建立认证文件，我使用的是apache的认证工具生成的密码复杂一点嘛（嫌麻烦直接手动输入echo woshimima >/alidata/passwd/rsync/rsyncd.pass） mkdir -p /alidata/passwd/rsycn htpasswd -cb /alidata/passwd/rsync/rsyncd.pass netho Netho123456789<br>chmod 600 /alidata/passwd/rsync/rsyncd.pass #为什么要这一步呢？和strict modes =yes/no有关系么，没时间实验了，擦 设定rsyncd.motd 文件; vim /alidata/passwd/rsync/rsyncd.motd 复制以下代码 ++++++++++++++++++++++++++++++++++++++++++++++ Welcome to use the rsync services! 2018------2099 ++++++++++++++++++++++++++++++++++++++++++++++ 正式配置： uid = ftp gid = ftp use chroot = no max connections = 36000 strict modes = yes hosts allow = 10.245.6.0/24 #配置主机ip可以空格，允许多个 hosts deny = 0.0.0.0/32 port = 873 pid file = /eshop/rsync/rsyncd.pid lock file = /eshop/rsync/rsync.lock log file = /eshop/rsync/rsyncd.log [eshop] #test为模块名称后续同步会用到 path = /home/test ignore errors #read only = false #此目录需要读写全部权限 read only = no list = false auth users = backup secrets file = /eshop/rsync/rsyncd.passwd ignore errors = no transfer logging = yes log format = %t: host %h (%a) %o %f (%l bytes).

Total %b bytes. 开放端口的方法： 方法一：命令行方式 1. 开放端口命令： /sbin/iptables -I INPUT -p tcp --dport 8080 -j ACCEPT 2.保存：/etc/rc.d/init.d/iptables save 3.重启服务：/etc/init.d/iptables restart 4.查看端口是否开放：/sbin/iptables -L -n 方法二：直接编辑/etc/sysconfig/iptables文件 1.编辑/etc/sysconfig/iptables文件：vi /etc/sysconfig/iptables 加入内容并保存：-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPT 2.重启服务：/etc/init.d/iptables restart 3.查看端口是否开放：/sbin/iptables -L -n 但是我用方法一一直保存不上，查阅网上发现直接修改文件不需要iptables save，重启下iptables 重新加载下配置。iptables save 是将当前的iptables写入到/etc/sysconfig/iptables。我不save直接restart也不行，所以还是方法二吧 查询端口是否有进程守护用如下命令grep对应端口，如80为端口号 例：netstat -nalp|grep 80
