Centos+Serync+inotify实时同步数据文件（二）
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@nagios01 qiuyuetao]# wget http://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@nagios01 qiuyuetao]# tar -zxvf sersync2.5.4_64bit_binary_stable_final.tar.gz -C /usr/local/（-C 解压到指定路径） [root@nagios01 qiuyuetao]# mv /usr/local/GNU-Linux-x86 sersync [root@nagios01 local]# tree sersync/ sersync/ ├── confxml.xml └── sersync2
2，规范 sersync 目录结构(自行抉择是否规范)
mkdir conf bin logs （配置文件放到conf、二进制命令Bin下、脚本logs下） [root@nagios01 local]# cd sersync/ [root@nagios01 sersync]# mkdir conf bin logs [root@nagios01 sersync]# mv confxml.xml conf/ [root@nagios01 sersync]# mv sersync2 bin/sersync [root@nagios01 sersync]# tree . ├── bin │ └── sersync ├── conf │ └── confxml.xml └── logs 3 directories, 2 files
3，编辑配置文件
备份 cp confxml.xml confxml.xmlq.$(date +%F)
4，更改及优化sersync 配置
（1）定义本地的同步目录 24 <localpath watch="/opt/tongbu">要同步的目录 25 <remote ip="127.0.0.1" name="tongbu1"/> 26 <!--<remote ip="192.168.8.39" name="tongbu"/>--> 同步到哪台机器 同步到那个模块目录 27 <!--<remote ip="192.168.8.40" name="tongbu"/>--> 28 </localpath> 修改后内容为： <sersync> <localpath watch="/usr/local/nagios/etc/cfgs"> <remote ip="192.168.1.206" name="cfgs"/> </localpath> <!--###############################################################--> <localpath watch="/usr/local/nagios/etc/objects"> <remote ip="192.168.1.206" name="objects"/> </localpath> <!--###############################################################--> 修改前 <rsync> 40 <commonParams params="-artuz"/> 41 <auth start="false" users="root" passwordfile="/etc/rsync.pas"/> 使用认证 42 <userDefinedPort start="false" port="874"/><!-- port=874 --> 43 <timeout start="false" time="100"/><!-- timeout=100 --> 44 <ssh start="false"/> 45 </rsync> 修改后内容为：拼接同步命令 <rsync> <commonParams params="-artuz"/> <auth start="true" users="rsync_backup" passwordfile="/etc/rsync.password"/> <userDefinedPort start="false" port="874"/><!-- port=874 --> <timeout start="true" time="100"/><!-- timeout=100 --> <ssh start="false"/> </rsync> 修改36-37行 失败后会写入log <failLog path="/tmp/rsync_fail_log.sh" timeToExecute="60"/><!--default every 60mins execute once--> 修改后内容 <failLog path="/usr/local/sersync/logs/rsync_fail_log.sh" timeToExecute="60"/><!--default every 60mins execute once-->
4,开启sersync守护进程同步数据（全局变量）
echo 'export PATH=$PATH:/usr/local/sersync/bin'>>/etc/profile tail -1 /etc/profile （查看是否添加） source /etc/profile （使/etc/Porofile 立即生效） which sersync （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@Server conf]# sersync -r -d -o /usr/local/sersync/conf/confxml.xml （启动过程） 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： /usr/local/sersync/conf/confxml.xml daemon thread num: 10 默认启动10个线程 parse xml config file host ip : localhost host port: 8008 daemon start，sersync run behind the console use rsync password-file : 密码文件 user is rsync_backup 用户 passwordfile is /etc/rsync.password config xml parse success please set /etc/rsyncd.conf max connections=0 Manually sersync working thread 12 工作线程数 = 1(primary thread) + 1(fail retry thread) + 10(daemon sub threads) Max threads numbers is: 32最大线程数 = 12(Thread pool nums) + 20(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 /usr/local/nagios/etc/cfgs && rsync -artuz -R --delete ./ --timeout=100 [email protected]::cfgs --password-file=/etc/rsync.password >/dev/null 2>&1 [root@nagios01 conf]# run the sersync: watch path is: /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@nagios01 conf]# touch /usr/local/nagios/etc/cfgs/1.txt /usr/local/nag ios/etc/objects/1.txt [root@nagios01 conf]# 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
cp confxml.xml confxml.xml_new cp confxml.xml cfgs_confxml.xml cp confxml.xml objects_confxml.xml
规范目录看着舒服多了
[root@nagios01 conf]# ll total 12 -rwxr-xr-x. 1 root root 2328 Feb 23 00:49 cfgs_confxml.xml -rwxr-xr-x. 1 root root 2339 Feb 23 00:50 objects_confxml.xml drwxr-xr-x. 2 root root 4096 Feb 23 00:51 tmp
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@nagios01 conf]# diff cfgs_confxml.xml objects_confxml.xml 23,24c23,24 < <localpath watch="/usr/local/nagios/etc/cfgs"> < <remote ip="192.168.1.206" name="cfgs"/> --- > <localpath watch="/usr/local/nagios/etc/objects"> > <remote ip="192.168.1.206" name="objects"/> 34c34 < <failLog path="/usr/local/sersync/logs/cfgs_rsync_fail_log.sh" timeToExecute="60"/><!--default every 60mins execute once--> --- > <failLog path="/usr/local/sersync/logs/objects_rsync_fail_log.sh" timeToExecute="60"/><!--default every 60mins execute once-->
9，更新sersync运行状态
[root@nagios01 conf]# ps -ef|grep sersync root 6134 1 0 Feb22 ? 00:00:00 sersync -r -d -o /usr/local/sersync/conf/confxml.xml root 7178 2428 0 00:55 pts/0 00:00:00 grep sersync [root@nagios01 conf]# pkill sersync [root@nagios01 conf]# ps -ef|grep sersync root 7187 2428 0 00:56 pts/0 00:00:00 grep sersync
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.xml sersync -r -d -o /usr/local/sersync/conf/objects_confxml.xml [root@nagios01 conf]# ps -ef |grep sersync root 7290 1 0 01:01 ? 00:00:00 sersync -r -d -o /usr/local/sersync/conf/cfgs_confxml.xml root 7308 1 0 01:01 ? 00:00:00 sersync -r -d -o /usr/local/sersync/conf/objects_confxml.xml root 7327 2428 0 01:01 pts/0 00:00:00 grep sersync
11，在做一下测试
[root@nagios01 conf]# touch /usr/local/nagios/etc/cfgs/2.txt /usr/local/nagios/etc/objects/2.txt [root@nagios01 conf]# 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
