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。
我们提供的服务有:成都网站设计、成都网站制作、外贸网站建设、微信公众号开发、网站优化、网站认证、工布江达ssl等。为上千多家企事业单位解决了网站和推广的问题。提供周到的售前咨询和贴心的售后服务,是有科学管理、有技术的工布江达网站制作公司
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.$(date +%F)
4,更改及优化sersync 配置
(1)定义本地的同步目录 24要同步的目录 25 修改后内容为:26 同步到哪台机器 同步到那个模块目录 27 28 修改前 40 修改后内容为:拼接同步命令41 使用认证 42 43 44 45 修改36-37行 失败后会写入log 修改后内容
4,开启sersync守护进程同步数据(全局变量)
echo 'export PATH=$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 rsync_backup@192.168.1.206::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]$tree ├── cfgs │ ├── 1.txt │ ├── cfgs.log ├── objects │ ├── objects.log
7,####如下是采用多实例的方法进行 同时同步2个目录#####
创建2个文件
cp confxml.xml confxml.xml_new cp confxml.xml cfgs_confxml.xml cp confxml.xml objects_confxml.xml
规范目录看着舒服多了
[root@nagios01 conf]# ll total 12 -rwxr-xr-x. 1 root root 2328 Feb 23 00:49 cfgs_confxml.xml -rwxr-xr-x. 1 root root 2339 Feb 23 00:50 objects_confxml.xml drwxr-xr-x. 2 root root 4096 Feb 23 00:51 tmp
8,配置文件内容删除多余节点目录 修改日志报错名称 如下是比对结果
[root@nagios01 conf]# diff cfgs_confxml.xml objects_confxml.xml 23,24c23,24 << --- > > 34c34 < --- >
9,更新sersync运行状态
[root@nagios01 conf]# ps -ef|grep sersync root 6134 1 0 Feb22 ? 00:00:00 sersync -r -d -o /usr/local/sersync/conf/confxml.xml root 7178 2428 0 00:55 pts/0 00:00:00 grep sersync [root@nagios01 conf]# pkill sersync [root@nagios01 conf]# ps -ef|grep sersync root 7187 2428 0 00:56 pts/0 00:00:00 grep sersync
10,同时启动2个配置文件,各自指定各自的配置文件(配置要求高些,进程数随之调整)
sersync -r -d -o /usr/local/sersync/conf/cfgs_confxml.xml sersync -r -d -o /usr/local/sersync/conf/objects_confxml.xml [root@nagios01 conf]# ps -ef |grep sersync root 7290 1 0 01:01 ? 00:00:00 sersync -r -d -o /usr/local/sersync/conf/cfgs_confxml.xml root 7308 1 0 01:01 ? 00:00:00 sersync -r -d -o /usr/local/sersync/conf/objects_confxml.xml root 7327 2428 0 01:01 pts/0 00:00:00 grep sersync
11,在做一下测试
[root@nagios01 conf]# touch /usr/local/nagios/etc/cfgs/2.txt /usr/local/nagios/etc/objects/2.txt [root@nagios01 conf]# tree /usr/local/nagios/etc/ /usr/local/nagios/etc/ ├── cfgs │ ├── 1.txt │ ├── 2.txt │ ├── cfgs.log ├── objects │ ├── 1.txt │ ├── 2.txt │ ├── objects.log │ [root@Nagios02 /usr/local/nagios/etc]$tree ├── cfgs │ ├── 1.txt │ ├── 2.txt │ ├── cfgs.log ├── objects │ ├── 1.txt │ ├── 2.txt │ ├── objects.log
Sersync 多实例 实时同步配置成功,希望大家多多支持。http://qiuyt.blog.51cto.com
