rsync结合inotify实现文件实时同步

rsync

1.复制工具

• 本地复制 远程复制
  cp dd

• 跨主机传递文件
  rz sz ftp scp rsync nfs samba drdb

2.rsync作用

实现文件的备份，可以是当前主机，也可以是远程主机；可以完全备份，也可以是增量备份

2.1功能

类似于cp的复制功能
将本地主机的一个文件复制到另一个位置下
将本地主机的文件推送到远程主机；也可以从远程主机拉取到本地

2.2使用模式

• shell模式：就是本地复制功能
• 远程shell模式：可以利用ssh来实现数据的加密传输到远程主机
• 服务器模式：rsync工作在守护进程模式下
• 列表：ls 显示内容不做操作

备注：确保各个主机时间一致ntpdate

实现文件的时间同步
rsync+inotify
rsync+sersync

rsync：只负责传递文件到远程主机
inotify sersync：将发生改变的文件找出来

2.2.1模式1：local

Local: rsync [OPTION…] SRC… [DEST]

选项：
-v 输出详细过程信息
-a 使用归档模式，如果复制目录必须使用此选项
-z 压缩方式传输
-p复制文件过程，保持文件属性不变
-e “ssh [-p22]”指定所使用的传输通道 -r 递归复制，先复制目录，然后复制子目录

复制的是目录

说明：md5sum在传递文件时候，会首先对比源和目的下的文件的特征码，只有特征码不同的时候，才会进行传递;rsync加ssh密钥认证方式，目的使用免密登录;先配置ssh，然后分发密钥

2.2.3模式3：守护进程模式

准备:关闭selinux;关闭防火墙;同步服务器时间

修改配置文件，让工作在守护进程模式

rsyncd.conf基本构成
全局参数
[模块1]
模块参数
[模块2]
模块参数全局参数：
pid file：指定rsync进程的pid文件的路径和名称
lock file：指定rsync进程的所在文件路径和名称
log file：rsync的日志文件路径和名称
uid：指定rsync进程以什么用户身份运行，必须是系统用户
gid：组用户模块参数：可以先写在全局部分
path：指定备份目录路径
use chroot ：是否将用户锁定在家目录中
max connections：指定可以进行同时连接的用户最大数量
read only:只读
write only：只写
list：true|false列表  设置用户可以显示的所有模块名称
auth users：指定访问模块需要使用的用户名，这里指的是虚拟用户
secrets file：虚拟用户名与密码的数据库文件
hosts allow:指定可以访问模块或者rsync服务端的ip地址
hosts deny：黑名单 补充：两个参数都没有，所有用户访问，只有allow，只允许白名单访问，白名单优先级高级黑名单
timeout：指定空闲超时时间

pid file=/var/lock/rsync.pid
lock file=/var/lock/rsync.lock
log file=/var/log/rsync.log[web]
path=/tmp/web
use chroot=no
write only=yes[nfs]
path=/tmp/web
user chroot=no

3.实例

3.1配置服务器端

3.1.1 创建配置文件

[root@harbor etc]# vi /ect/rsyncd.conf
uid = rsync
gid = rsync
use chroot = no
max connection = 100
timeout = 100
pid file = /var/lock/rsync.pid
lock file = /var/lock/rsync.lock
log file =  /var/log/rsync.log[mod1]
path = /rsync/web1
read only = false
hosts allow = 10.4.0.0/8
auth users = vuser1
fake super = yes
secrets file = /rsync/rsync.passwd
list = false[mod2]
path = /rsync/web2
read only = false
hosts allow = 10.4.0.0/8
auth users = vuser2
fake super = yes
secrets file = /rsync/rsync.passwd
list = false

3.1.2.创建目录

[root@harbor ~]# mkdir -pv /rsync/web{1,2}
mkdir: 已创建目录 "/rsync/web1"
mkdir: 已创建目录 "/rsync/web2"
#修改属组
chown rsync:rsync /rsync/web{1,2}

3.1.3.创建用户，运行rsync的系统用户

[root@harbor ~]# grep rsync /etc/passwd
[root@harbor ~]# groupadd -r rsync
[root@harbor ~]# useradd -r -s /sbin/nologin -g rsync rsync

3.1.4.启动rsync

[root@harbor ~]# rsync --daemon
[root@harbor ~]#
[root@harbor ~]#
[root@harbor ~]# rsync --daemon
failed to create pid file /var/lock/rsync.pid: File exists
# 引用其他配置文件 --config=/path/to/confile

3.1.5.检查rsync端口，默认是873

[root@harbor ~]# ss -lnt|grep 873
LISTEN     0      5            *:873                      *:*
LISTEN     0      5         [::]:873                   [::]:*
[root@harbor ~]# netstat -ntlp|grep 873
tcp        0      0 0.0.0.0:873             0.0.0.0:*               LISTEN      84330/rsync
tcp6       0      0 :::873                  :::*                    LISTEN      84330/rsync
[root@harbor ~]# lsof -i :873
COMMAND   PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
rsync   84330 root    3u  IPv4 496039      0t0  TCP *:rsync (LISTEN)
rsync   84330 root    5u  IPv6 496040      0t0  TCP *:rsync (LISTEN)

3.1.6.创建虚拟文件用户

[root@harbor ~]# cd /rsync/
[root@harbor rsync]# touch rsync.passwd
[root@harbor rsync]# chmod 600 rsync.passwd #权限600
[root@harbor rsync]# vi rsync.passwd
vuser1:123456
vuser2:123456

3.2配置客户端

使用格式
rsync [options] [user@]host::moduleName /path/
rsync [options] /path/ [user@]host::moduleName

每次传输需要输入密码

3.2.1.创建密码文件

echo "123456">/etc/rsync.passwd
# 修改所属组
chmod 600 /etc/rsync.passwd

3.2.2.使用rsync来传递数据到服务器的端模块mod1中

rsync -avz /root/test/ vuser1@10.4.7.9::mod1 --password-file=/etc/rsync.passwd

注：–password-file=/etc/rsync.passwd 指定密码文件地址，不需要手动输入密码

报错：rsync: chgrp “.new.txt.FMIDJB” (in mod1) failed: Operation not permitted (1)

[root@hdss7-6 test]# rsync -avz /root/test/ vuser1@10.4.7.9::mod1 --password-file=/etc/rsync.passwd
sending incremental file list

total size is 207  speedup is 0.27
rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1179) [sender=3.1.2]

解决办法：fake super=yes 用于允许非root用户,在备份目录创建文件

[root@hdss7-6 test]# rsync -avz /root/test/ vuser1@10.4.7.9::mod1 --password-file=/etc/rsync.passwd
sending incremental file list
./
new.txt
old.txt
txt.patchsent 379 bytes  received 132 bytes  146.00 bytes/sec
total size is 207  speedup is 0.41

或者解决办法

经排查是由于-a参数导致的，因为-a是归档模式传输，并保持所有文件属性，等价于-rtopgDl（还没有具体深入研究），可以使用下面这个命令替代rsync -rltDvz /opt/ rsync_backup@10.0.0.41::backup

4 总结

4.1服务器端的配置

1.创建配置文件
2.创建密码文件，修改权限为600
3.创建系统用户
4.创建模块对应的目录，修改目录的属主属组为系统用户
5.启动daemon模式

4.2客户端配置：

1.创建虚拟用户的密码文件，权限为600
2.向模块传输文件或者从目录拉取文件

如果出现错误：
1.检查日志
2.检查selinux、iptables是否启动
3.检查虚拟用户的目录权限所有组是否正确，以及secrets密码是600

5.重启服务

[root@harbor rsync]# ps -ef|grep rsync
root      84330      1  0 11:22 ?        00:00:00 rsync --daemon

服务脚本存放位置
CentOS 7及以上版本
系统服务 ：存放在 /usr/lib/systemd/system/ 目录下。

用户服务 ：存放在 /usr/lib/systemd/user/ 目录下。

CentOS 6
服务脚本通常放在 /etc/init.d/ 目录下。

编写rsync脚本/usr/lib/systemd/system/rsyncd.service

6.执行操作

6.1 10.4.7.6客户端

[root@hdss7-6 ~]# rsync -avz /root/test vuser1@10.4.7.9::mod1
Password:
sending incremental file list
test/
test/10.txt
test/new.txt
test/old.txt
test/txt.patchsent 490 bytes  received 104 bytes  108.00 bytes/sec
total size is 203  speedup is 0.34

6.2 10.4.7.9服务端

[root@harbor web1]# pwd
/rsync/web1
[root@harbor web1]# ls
test

rsync -avz /root/test vuser1@10.4.7.9::mod1 
会将整个test目录传递rsync -avz /root/test/ vuser1@10.4.7.9::mod1
传递目录下面的文件

–delete 让客户端与服务器端的文件完全一致
–exclude 在进行文件传送的时候，排除指定的文件

7. rsync客户端排除指定文件方式

7. 1方式一：排除一个文件–exclude=file

[root@hdss7-6 test]# rsync -avz /root/test/ --exclude=3.txt vuser1@10.4.7.9::mod1
Password:
sending incremental file list
./
1.txt
10.txt
2.txt
4.txt
5.txt
6.txt
7.txt
8.txt
9.txt
new.txt
old.txt
txt.patchsent 887 bytes  received 255 bytes  175.69 bytes/sec
total size is 203  speedup is 0.18

7. 2方式二：排除多个个文件–exclude={file,file2,file3}

[root@hdss7-6 test]# touch {12,13,14}.txt
[root@hdss7-6 test]# ls
10.txt  12.txt  13.txt  14.txt  1.txt  2.txt  3.txt  4.txt  5.txt  6.txt  7.txt  8.txt  9.txt  new.txt  old.txt  txt.patch
[root@hdss7-6 test]# rsync -avz /root/test/ --exclude={3.txt,13.txt,14.txt} vuser1@10.4.7.9::mod1
Password:
sending incremental file list
./
12.txtsent 331 bytes  received 46 bytes  68.55 bytes/sec
total size is 203  speedup is 0.54

7. 3 方式三：通配符的效果

[root@hdss7-6 test]# touch {a,b,c}.txt
[root@hdss7-6 test]# touch {a,b,c}.conf
[root@hdss7-6 test]# rsync -avz /root/test/ --exclude=*.txt vuser1@10.4.7.9::mod1
Password:
sending incremental file list
./
a.conf
b.conf
c.confsent 242 bytes  received 84 bytes  59.27 bytes/sec
total size is 143  speedup is 0.44

7. 4服务端配置

man rsyncd.conf配置文件

 excludeThis parameter takes a space-separated list of daemon exclude patterns.  As with the client --exclude option, patterns can be qualified with "- " or "+ "to explicitly indicate exclude/include.  Only one "exclude" parameter can apply to a given module.  See the "filter" parameter for a description  of  howexcluded files affect the daemon.

修改rsyncd.conf模块的参数exclude，列表以空格分开

exclude =a.txt b.txt c.txt

8.完全同步原理

在文件的传输过程中
–delete 使目标目录内容和源保持目录一致,删除不同的文件
1.测试客户端

2.2 解压文件

[root@hdss7-6 ~]# tar xvf sersync2.5.4_64bit_binary_stable_final.tar.gz -C /root/
GNU-Linux-x86/
GNU-Linux-x86/sersync2
GNU-Linux-x86/confxml.xml

2.3. 创建目录，复制配置文件，移动bin文件

[root@hdss7-6 ~]# mv GNU-Linux-x86 sersync
[root@hdss7-6 ~]# cd sersync
[root@hdss7-6 sersync]# ls
confxml.xml  sersync2
[root@hdss7-6 sersync]# mkdir bin conf logs
[root@hdss7-6 sersync]# cp confxml.xml ./conf/confxml1.xml
[root@hdss7-6 sersync]# mv sersync2 ./bin/sersync
[root@hdss7-6 sersync]# ls
bin  conf  confxml.xml  logs

2.4. 配置文件

1.设置监控事件类型
2.设置rsync服务端的ip，模块名称，本地监控的目录
3.设置传输文件的时候需要身份认证信息相关信息
4.设置传输失败信息记录的文件位置

<?xml version="1.0" encoding="ISO-8859-1"?>
<head version="2.5"><host hostip="localhost" port="8008"></host><debug start="false"/><fileSystem xfs="false"/><filter start="false"><exclude expression="(.*)\.svn"></exclude><exclude expression="(.*)\.gz"></exclude><exclude expression="^info/*"></exclude><exclude expression="^static/*"></exclude></filter><inotify><delete start="true"/><createFolder start="true"/><createFile start="true"/><closeWrite start="false"/><moveFrom start="false"/><moveTo start="false"/><attrib start="true"/><modify start="true"/></inotify><sersync><!--设置rsync服务端的ip，模块名称，本地监控的目录--><localpath watch="/root/test/"><remote ip="10.4.7.9" name="mod1"/><!--<remote ip="192.168.8.39" name="tongbu"/>--><!--<remote ip="192.168.8.40" name="tongbu"/>--></localpath><!--设置传输文件的时候需要身份认证信息相关信息--><rsync><commonParams params="-artuz"/><auth start="true" users="vuser1" passwordfile="/etc/rsync.passwd"/><userDefinedPort start="false" port="874"/><!-- port=874 --><timeout start="false" time="100"/><!-- timeout=100 --><ssh start="false"/></rsync<!--设置传输失败信息记录的文件位置--><failLog path="/tmp/rsync_fail_log.sh" timeToExecute="60"/><!--default every 60mins 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/images"/></localpath></plugin>
</head>

2.5. 配置环境变量

 echo "export PATH=$PATH:/root/sersync/bin/">/etc/profile.d/sersync.sh#配置生效source /etc/profile

2.6. 测试sersync

[root@hdss7-6 sersync]# sersync -h
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
_______________________________________________________
参数-d:启用守护进程模式
参数-r:在监控前，将监控目录与远程主机用rsync命令推送一遍
c参数-n: 指定开启守护线程的数量，默认为10个
参数-o:指定配置文件，默认使用confxml.xml文件
参数-m:单独启用其他模块，使用 -m refreshCDN 开启刷新CDN模块
参数-m:单独启用其他模块，使用 -m socket 开启socket模块
参数-m:单独启用其他模块，使用 -m http 开启http模块
不加-m参数，则默认执行同步程序

2.7. 执行监控命令

#测试同步，没问题执行监控
rsync -artuz -R --delete ./   --include="5.txt" --exclude=*  vuser1@10.4.7.9::mod1 --password-file=/etc/rsync.passwd
#修改权限
[root@hdss7-6 test]# chmod 600 /etc/rsync.passwd
[root@hdss7-6 test]# sersync -rdo /root/sersync/conf/confxml1.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：  /root/sersync/conf/confxml1.xml
daemon thread num: 10
parse xml config file
host ip : localhost     host port: 8008
will ignore the inotify createFile event
daemon start，sersync run behind the console
use rsync password-file :
user is vuser1
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 /root/test && rsync -artuz -R --delete ./ vuser1@10.4.7.9::mod1 --password-file=/etc/rsync.passwd >/dev/null 2>&1
[root@hdss7-6 test]# run the sersync:
watch path is: /root/test
#查看进程
[root@hdss7-6 /]# ps -aux|grep sersync
root      16438  0.0  0.0  92324   704 ?        Ssl  16:17   0:00 sersync -rdo /root/sersync/conf/confxml1.xml

2.8. 测试文件

[root@hdss7-6 test]# touch {1,2,3}.txt
[root@hdss7-6 test]# rm -rf {1,2,3}.txt

2.9.在10.4.7.9观察

2.10 脚本（后面未测）

#!/bin/bash
flist="/root/test"
path="/tmp/"
backdir="/backup"
dabao='/bak'
serfile="/etc/rsync.passwd"
ipaddr=$(ip addr|sed -n '9p'|egrep '[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}'|sed -nr 's#^.*inet (.*) brd(.*)$#\1#gp'|sed -rn 's#^(.*)/24#\1#gp')
cp -aL $flist $backdir$bak
[ -d $backdir/$ipaddr ] || mkdir -p $backdir/$ipaddr
cd $backdir
tar -cf $ipaddr`date +%F%T`.tar.gz $bakfind $backdir -mtime +7 -exec rm -rf {} \;
rsync -az -delete $backdir/ vuser1@10.4.7.9::mod1 --password-file=$serfile

[root@harbor bak]# ip addr|sed -n '9p'|egrep '[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}'|sed -nr 's#^.*inet (.*) brd(.*)$#\1#gp'|sed -rn 's#^(.*)/24#\1#gp'
10.4.7.9

md5验证

[root@harbor bak]# ls
2025-01-16.tar.gz  cron  html  iptables  log  rc.local
[root@harbor bak]# md5sum 2025-01-16.tar.gz
