Centos7.0系统下Rsync+sersync实现多文件数据实时增量同步

前言：@H_502_3@

一、为什么要用Rsync+sersync架构?@H_502_3@

1、sersync是基于Inotify开发的，类似于Inotify-tools的工具@H_502_3@

2、sersync可以记录下被监听目录中发生变化的（包括增加、删除、修改）具体某一个文件或某一个目录的名字，然后使用rsync同步的时候，只同步发生变化的这个文件或者这个目录。@H_502_3@

@H_502_3@

二、Rsync+Inotify-tools与Rsync+sersync这两种架构有什么区别？@H_502_3@

1、Rsync+Inotify-tools
@H_502_3@

（1）：Inotify-tools只能记录下被监听的目录发生了变化（包括增加、删除、修改），并没有把具体是哪个文件或者哪个目录发生了变化记录下来；@H_502_3@

（2）：rsync在同步的时候，并不知道具体是哪个文件或者哪个目录发生了变化，每次都是对整个目录进行同步，当数据量很大时，整个目录同步非常耗时（rsync要对整个目录遍历查找对比文件），因此，效率很低。@H_502_3@

2、Rsync+sersync@H_502_3@

（1）：sersync可以记录下被监听目录中发生变化的（包括增加、删除、修改）具体某一个文件或某一个目录的名字；@H_502_3@

（2）：rsync在同步的时候，只同步发生变化的这个文件或者这个目录（每次发生变化的数据相对整个同步目录数据来说是很小的，rsync在遍历查找比对文件时，速度很快），因此，效率很高。@H_502_3@

小结：当同步的目录数据量不大时，建议使用Rsync+Inotify-tools；当数据量很大（几百G甚至1T以上）、文件很多时，建议使用Rsync+sersync。@H_502_3@

环境说明：@H_502_3@

操作系统：CentOS 7.0@H_502_3@

源服务器：192.168.1.51@H_502_3@

目标服务器：192.168.1.52@H_502_3@

目的：@H_502_3@

把源服务器上/data/image /data/pic两个目录@H_502_3@

实时同步到目标服务器的data/image /data/pic下@H_502_3@

@H_502_3@

具体操作：@H_502_3@

一、目标服务器安装Rsync服务端@H_502_3@

1、关闭SELINUX@H_502_3@

vi /etc/selinux/config@H_502_3@

@H_502_3@

SELINUX=disabled@H_502_3@

setenforce 0#立即生效

@H_502_3@

2. 配置防火墙IPTABLES@H_502_3@

@H_502_3@

[root@master2 ~]# vim /etc/sysconfig/iptables

@H_502_3@

增加规则：-A INPUT -p tcp -m state --state NEW -m tcp --dport 873 -j ACCEPT@H_502_3@

@H_502_3@

iptables -L -v -n 查看防火墙状态，873端口是否开放@H_502_3@

@H_502_3@

3、检查是否安装rsync
@H_502_3@

[root@master2 ~]# rpm -qa|grep rsync@H_502_3@

rsync-3.0.9-15.el7.x86_64@H_502_3@

@H_502_3@

4、配置rsync的配置文件@H_502_3@

@H_502_3@

vim /etc/rsyncd.conf@H_502_3@

#Rsync configuration:@H_502_3@

uid = root @H_502_3@

gid = root @H_502_3@

use chroot = no @H_502_3@

port = 873 @H_502_3@

max connections = 2000 @H_502_3@

timeout = 200 @H_502_3@

log file = /var/run/rsyncd.log @H_502_3@

pid file = /var/run/rsyncd.pid @H_502_3@

lock file = /var/run/rsyncd.lock @H_502_3@

read only = false @H_502_3@

auth users = lyc @H_502_3@

secrets file = /etc/rsyncd.secret @H_502_3@

@H_502_3@

hosts allow = 192.168.1.0/255 @H_502_3@

hosts deny = 0.0.0.0/32 @H_502_3@

list = yes@H_502_3@

ignore errors = yes@H_502_3@

@H_502_3@

[image] @H_502_3@

path = /data/image@H_502_3@

@H_502_3@

[pic]@H_502_3@

pate = /data/pic @H_502_3@

@H_502_3@

注解@H_502_3@

#Rsync configuration:@H_502_3@

uid = root #设置rsync运行权限为root@H_502_3@

gid = root #设置rsync运行权限为root@H_502_3@

use chroot = no # 安全相关，默认为true，修改为no，增加对目录文件软连接的备份@H_502_3@

port = 873 # 指定rsync服务的默认端口号@H_502_3@

max connections = 2000 # 并发连接数@H_502_3@

timeout = 200 # 超时时间（秒）@H_502_3@

log file = /var/run/rsyncd.log # 指定日志文件位置，启动rsync后自动产生这个文件，无需提前创建@H_502_3@

pid file = /var/run/rsyncd.pid # 指定rsync的pid目录@H_502_3@

lock file = /var/run/rsyncd.lock # 指定rsync的锁文件【重要】,支持max connections参数的锁文件@H_502_3@

read only = false # no客户端可上传文件,yes只读@H_502_3@

auth users = lyc #执行数据同步的用户名，可以设置多个，用英文状态下逗号隔开@H_502_3@

secrets file = /etc/rsyncd.secret #用户认证配置文件，里面保存用户名称和密码，后面会创建这个文件@H_502_3@

@H_502_3@

hosts allow = 192.168.1.0/255 #允许进行数据同步的客户端IP地址段，可以设置多个，用英文状态下逗>号隔开@H_502_3@

hosts deny = 0.0.0.0/32 #禁止数据同步的客户端IP地址，这里设置了不禁止@H_502_3@

#################################################
@H_502_3@

[image] # 模块@H_502_3@

path = /home/ces/ #rsync服务端数据目录路径@H_502_3@

@H_502_3@

5、创建rsync同步密码文件，并设置权限为600@H_502_3@

[root@master2 ~]# echo "lyc:test123" > /etc/rsyncd.secret@H_502_3@

[root@master2 ~]# chmod 600 /etc/rsyncd.secret@H_502_3@

[root@master2 ~]# ll //etc/rsyncd.secret@H_502_3@

-rw------- 1 root root 14 4月 18 09:25 /[root@master2 ~]# cat /etc/rsyncd.secret@H_502_3@

lyc:test123@H_502_3@

@H_502_3@

6.启动rsync守护进程，并写入开机自启动@H_502_3@

[root@master2 ~]# rsync --daemon@H_502_3@

[root@master2 ~]# ps -ef | grep rsync@H_502_3@

root 1662 1 0 09:34 ? 00:00:00 rsync --daemon@H_502_3@

root 6310 6068 0 17:02 pts/0 00:00:00 grep --color=auto rsync@H_502_3@

[root@master2 ~]# netstat -nulpt| grep rsync@H_502_3@

tcp 0 0 0.0.0.0:873 0.0.0.0:* LISTEN 1662/rsync @H_502_3@

tcp6 0 0 :::873 :::* LISTEN 1662/rsync @H_502_3@

设置开机自启动,写入到/etc/rc.local里面@H_502_3@

vim /etc/rc.local@H_502_3@

# rsync server progress@H_502_3@

/usr/bin/rsync --daemon --config=/etc/rsyncd.conf
@H_502_3@

7.创建相关待同步的目录/home/ces/并授予权限@H_502_3@

@H_502_3@

[root@master2 ~]# mkdir -p /data/image/data/pic@H_502_3@

[root@master2 ~]# chown -R root.root /data/image
@H_502_3@

@H_502_3@

二、在源服务器安装配置Rsync服务端+配置sersync@H_502_3@

1、按照上面步骤配置按照Rsync服务端，需要注意的是创建rsync同步密码文件，内容只需要填写密码：test123
@H_502_3@

@H_502_3@

[root@master1 ~]# echo "test123" > /etc/rsyncd.secret@H_502_3@

[root@master1 ~]# chmod 600 /etc/rsyncd.secret@H_502_3@

[root@master1 ~]# ll -rw------- 1 root root 14 4月 18 09:25 /etc/rsync.password@H_502_3@

[root@master1 ~]# cat /etc/rsyncd.secret@H_502_3@

test123@H_502_3@

2、手动测试rsync同步情况，此步非常关键，如果测试不成功，后面的sersync配好了也不会同步数据。@H_502_3@

[root@master1 lyc]# rm -rf /test/@H_502_3@

[root@master1 lyc]# mkdir -p /test/@H_502_3@

[root@master1 lyc]# touch /test/lyc{1,2,3}{a,b,c}@H_502_3@

[root@master1 lyc]# ls /test/@H_502_3@

lyc1a lyc1b lyc1c lyc2a lyc2b lyc2c lyc3a lyc3b lyc3c@H_502_3@

@H_502_3@

[root@master1 lyc]# rsync -avzP /lyc/ lyc@192.168.1.52::rsync --password-file=/etc/rsyncd.secret@H_502_3@

sending incremental file list@H_502_3@

@H_502_3@

3、在源服务器上执行推送命令后，在目的服务器上查看同步目录/home/ces中的内容，如果内容同步完成，进行sersync的配置；未完成，检查rsync配置及认证用户密码信息。@H_502_3@

@H_502_3@

三、源服务器上开始部署sersync服务@H_502_3@

1、下载sersync@H_502_3@

@H_502_3@

[root@master1 lyc]#wget -chttps://sersync.googlecode.com/files/sersync2.5.4_64bit_binary_stable_final.tar.gz@H_502_3@

[root@master1 lyc]#tar -zxf sersync2.5.4_64bit_binary_stable_final.tar.gz-C/usr/local/@H_502_3@

[root@master1 lyc]#mvGNU-Linux-x86/usr/local/sersync@H_502_3@

由于谷歌的原因，不能成功下载的话，请手动下载上传到源服务器端@H_502_3@

@H_502_3@

2、配置sersync@H_502_3@

@H_502_3@

[root@master1 local]#mkdir -p sersync/bin sersync/image sersync/pic@H_502_3@

[root@master1 local]#cp sersync/confxml.xmlsersync/image/@H_502_3@

[root@master1 local]#mv sersync/serynce2sersync/bin/@H_502_3@

@H_502_3@

3、修改配置文件image/confxml.xml、pic/confxml.xml
@H_502_3@

@H_502_3@

</head>@H_502_3@

@H_502_3@

只需要修改以下配置：@H_502_3@

24行：<localpath="/data/image"> #源服务器本地同步目录@H_502_3@

25行：<remote="image"/> #目的服务器同步目录@H_502_3@

@H_502_3@

31行：<auth/> #指定rsync的用户和密码文件@H_502_3@

32行：<userDefinedPort #指定rsync的端口@H_502_3@

33行：<timeoutstart="true"time"200" #超时时间（秒）@H_502_3@

@H_502_3@

4、创建源服务器端同步目录@H_502_3@

@H_502_3@

[root@master2 ~]# mkdir -p /data/image/data/pic@H_502_3@

[root@master2 ~]# chown -R root.root/data/image/data/pic@H_502_3@

@H_502_3@

5、把sersync的执行脚本加入到PATH并启动sersync@H_502_3@

[root@master1 ces]#echo "export PATH=$PATH:/usr/local/sersync/bin/" >>/etc/profile@H_502_3@

[root@master1 ces]#source/etc/profile@H_502_3@

[root@master1 ces]#sersync2 -d -r -o /usr/local/sersync/image/confxml.xml@H_502_3@

[root@master1 ces]#sersync2 -d -r -o /usr/local/sersync/confxml.xml@H_502_3@

6、启动命令后返回结果如下为正常：@H_502_3@

set the system param@H_502_3@

execute：echo 50000000 > /proc/sys/fs/inotify/max_user_watches@H_502_3@

execute：echo 327679 > /proc/sys/fs/inotify/max_queued_events@H_502_3@

parse the command param@H_502_3@

config xml parse success@H_502_3@

please set /etc/rsyncd.conf max connections=0 Manually@H_502_3@

sersync working thread 12 = 1(primary thread) + 1(fail retry thread) + 10(daemon sub threads)@H_502_3@

Max threads numbers is: 22 = 12(Thread pool nums) + 10(Sub threads)@H_502_3@

please according your cpu ，use -n param to adjust the cpu rate@H_502_3@

------------------------------------------@H_502_3@

rsync the directory recursivly to the remote servers once@H_502_3@

working please wait...@H_502_3@

execute command: cd /ces && rsync -artuz -R --delete ./ --port=873 --timeout=200 lyc@192.168.1.52::rsync --password-file=/etc/rsyncd.secret >/dev/null 2>&1@H_502_3@

run the sersync:@H_502_3@

watch path is: /data/image@H_502_3@

@H_502_3@

7、设置开机启动sersync@H_502_3@

@H_502_3@

[root@master1]echo "sersync2 -r -d -o /usr/local/sersync/image/confxml.xml" >> /etc/rc.d/rc.local@H_502_3@

/picconfxml.xml" >> /etc/rc.d/rc.local@H_502_3@

@H_502_3@

四、测试@H_502_3@

1、源服务器端创建文件@H_502_3@

@H_502_3@

[root@master1]# touch lyc.txt /data/image /data/pic@H_502_3@

[root@master1 /]# cd/data/image@H_502_3@

[root@master1 image]# ls@H_502_3@

lyc.txt@H_502_3@

[root@master1 /]# cd/data/pic@H_502_3@

[root@master1 pic]# ls@H_502_3@

lyc.txt@H_502_3@

@H_502_3@

2、目的服务器端查看@H_502_3@

[root@master2 /]# cd /data/image@H_502_3@

[root@master2 image]# ls@H_502_3@

[root@master2 /]# cd/data/pic@H_502_3@

[root@master2 pic]# ls@H_502_3@

lyc.txt@H_502_3@

@H_502_3@

3、同步失败解决办法@H_502_3@

目的服务器端执行命令@H_502_3@

rsync --daemon
