Centos+Serync+inotify实时同步数据文件（二）

2025-02-14 技术教程

这2天一直忙其它的事，忘记把剩余的同步过程分享到博客中，望谅解！上周把rsync已经配置完成，可以手动的同步，下面我们将使用Serync进行实时的同步，其实就手动同步而言也可以配置crontab定时备份，因人而异方法很多，选一种适合你自己的。

三、Serync Configuration

首先下载软件

[root@nagios01/]#cd/home/qiuyuetao/[root@nagios01qiuyuetao]#wgethttp://sersync.googlecode.com/files/sersync2.5.4_64bit_binary_stable_final.tar.gz

【http://code.google.com/p/sersync/】下载网站

1，安装sersync

[root@nagios01qiuyuetao]#tar-zxvfsersync2.5.4_64bit_binary_stable_final.tar.gz-C/usr/local/（-C解压到指定路径）[root@nagios01qiuyuetao]#mv/usr/local/GNU-Linux-x86sersync[root@nagios01local]#treesersync/sersync/├──confxml.xml└──sersync2

2，规范 sersync 目录结构(自行抉择是否规范)

mkdirconfbinlogs（配置文件放到conf、二进制命令Bin下、脚本logs下）[root@nagios01local]#cdsersync/[root@nagios01sersync]#mkdirconfbinlogs[root@nagios01sersync]#mvconfxml.xmlconf/[root@nagios01sersync]#mvsersync2bin/sersync[root@nagios01sersync]#tree.├──bin│└──sersync├──conf│└──confxml.xml└──logs3directories,2files

3，编辑配置文件

备份cpconfxml.xmlconfxml.xmlq.$(date+%F)

4，更改及优化sersync 配置

（1）定义本地的同步目录24<localpathwatch="/opt/tongbu">要同步的目录25<remoteip="127.0.0.1"name="tongbu1"/>26同步到哪台机器同步到那个模块目录2728</localpath>修改后内容为：<sersync><localpathwatch="/usr/local/nagios/etc/cfgs"><remoteip="192.168.1.206"name="cfgs"/></localpath><localpathwatch="/usr/local/nagios/etc/objects"><remoteip="192.168.1.206"name="objects"/></localpath>修改前<rsync>40<commonParamsparams="-artuz"/>41<authstart="false"users="root"passwordfile="/etc/rsync.pas"/>使用认证42<userDefinedPortstart="false"port="874"/>43<timeoutstart="false"time="100"/>44<sshstart="false"/>45</rsync>修改后内容为：拼接同步命令<rsync><commonParamsparams="-artuz"/><authstart="true"users="rsync_backup"passwordfile="/etc/rsync.password"/><userDefinedPortstart="false"port="874"/><timeoutstart="true"time="100"/><sshstart="false"/></rsync>修改36-37行失败后会写入log<failLogpath="/tmp/rsync_fail_log.sh"timeToExecute="60"/>修改后内容<failLogpath="/usr/local/sersync/logs/rsync_fail_log.sh"timeToExecute="60"/>

4,开启sersync守护进程同步数据（全局变量）

echo'exportPATH=$PATH:/usr/local/sersync/bin'>>/etc/profiletail-1/etc/profile（查看是否添加）source/etc/profile（使/etc/Porofile立即生效）whichsersync（查看sersync命令路径能否找到）

5，《启动同步命令》

sersync -r（先做一次同步） -d(后台启动) -o（指定文件） /usr/local/sersync/conf/confxml.xml

sersync-r-d-o/usr/local/sersync/conf/confxml.xml

[root@Serverconf]#sersync-r-d-o/usr/local/sersync/conf/confxml.xml（启动过程）setthesystemparamexecute：echo50000000>/proc/sys/fs/inotify/max_user_watchesexecute：echo327679>/proc/sys/fs/inotify/max_queued_eventsparsethecommandparamoption:-rrsyncallthelocalfilestotheremoteserversbeforethesersyncworkoption:-drunasadaemonoption:-oconfigxmlname：/usr/local/sersync/conf/confxml.xmldaemonthreadnum:10默认启动10个线程parsexmlconfigfilehostip:localhosthostport:8008daemonstart，sersyncrunbehindtheconsoleusersyncpassword-file:密码文件userisrsync_backup用户passwordfileis/etc/rsync.passwordconfigxmlparsesuccesspleaseset/etc/rsyncd.confmaxconnections=0Manuallysersyncworkingthread12工作线程数=1(primarythread)+1(failretrythread)+10(daemonsubthreads)Maxthreadsnumbersis:32最大线程数=12(Threadpoolnums)+20(Subthreads)pleaseaccordingyourcpu，use-nparamtoadjustthecpurate------------------------------------------rsyncthedirectoryrecursivlytotheremoteserversonceworkingpleasewait...executecommand:cd/usr/local/nagios/etc/cfgs&&rsync-artuz-R--delete./--timeout=100rsync_backup@192.168.1.206::cfgs--password-file=/etc/rsync.password>/dev/null2>&1[root@nagios01conf]#runthesersync:watchpathis:/usr/local/nagios/etc/cfgs成功

6，#####测试结果：发现一个问题，仅能同步一个模块目录 cfgs模块 / objects 没有同步

[root@nagios01conf]#touch/usr/local/nagios/etc/cfgs/1.txt/usr/local/nagios/etc/objects/1.txt[root@nagios01conf]#tree/usr/local/nagios/etc//usr/local/nagios/etc/├──cfgs│├──1.txt│├──cfgs.log├──objects│├──1.txt│├──objects.log│[root@Nagios02/usr/local/nagios/etc]$tree├──cfgs│├──1.txt│├──cfgs.log├──objects│├──objects.log

7，####如下是采用多实例的方法进行同时同步2个目录#####

创建2个文件

cpconfxml.xmlconfxml.xml_newcpconfxml.xmlcfgs_confxml.xmlcpconfxml.xmlobjects_confxml.xml

规范目录看着舒服多了

[root@nagios01conf]#lltotal12-rwxr-xr-x.1rootroot2328Feb2300:49cfgs_confxml.xml-rwxr-xr-x.1rootroot2339Feb2300:50objects_confxml.xmldrwxr-xr-x.2rootroot4096Feb2300:51tmp

8，配置文件内容删除多余节点目录修改日志报错名称如下是比对结果

[root@nagios01conf]#diffcfgs_confxml.xmlobjects_confxml.xml23,24c23,24<<localpathwatch="/usr/local/nagios/etc/cfgs"><<remoteip="192.168.1.206"name="cfgs"/>---><localpathwatch="/usr/local/nagios/etc/objects">><remoteip="192.168.1.206"name="objects"/>34c34<<failLogpath="/usr/local/sersync/logs/cfgs_rsync_fail_log.sh"timeToExecute="60"/>---><failLogpath="/usr/local/sersync/logs/objects_rsync_fail_log.sh"timeToExecute="60"/>

9，更新sersync运行状态

[root@nagios01conf]#ps-ef|grepsersyncroot613410Feb22?00:00:00sersync-r-d-o/usr/local/sersync/conf/confxml.xmlroot71782428000:55pts/000:00:00grepsersync[root@nagios01conf]#pkillsersync[root@nagios01conf]#ps-ef|grepsersyncroot71872428000:56pts/000:00:00grepsersync

10，同时启动2个配置文件，各自指定各自的配置文件（配置要求高些，进程数随之调整）

sersync-r-d-o/usr/local/sersync/conf/cfgs_confxml.xmlsersync-r-d-o/usr/local/sersync/conf/objects_confxml.xml[root@nagios01conf]#ps-ef|grepsersyncroot72901001:01?00:00:00sersync-r-d-o/usr/local/sersync/conf/cfgs_confxml.xmlroot73081001:01?00:00:00sersync-r-d-o/usr/local/sersync/conf/objects_confxml.xmlroot73272428001:01pts/000:00:00grepsersync

11，在做一下测试

[root@nagios01conf]#touch/usr/local/nagios/etc/cfgs/2.txt/usr/local/nagios/etc/objects/2.txt[root@nagios01conf]#tree/usr/local/nagios/etc//usr/local/nagios/etc/├──cfgs│├──1.txt│├──2.txt│├──cfgs.log├──objects│├──1.txt│├──2.txt│├──objects.log│[root@Nagios02/usr/local/nagios/etc]$tree├──cfgs│├──1.txt│├──2.txt│├──cfgs.log├──objects│├──1.txt│├──2.txt│├──objects.log
