sersync2 实时同步配置
在同步服务器上开启sersync,将监控路径中的文件同步到目标服务器,因此需要在同步服务器配置sersync,在同步目标服务器配置rsync。
一、同步目标服务器配置rsync
- # rpm -qa |grep rsync
- rsync-2.6.8-3.1
- # rpm -e rsync-2.6.8-3.1
unistall系统自带安装的rsync,安装3.0版的rsync
- # wget -c http://rsync.samba.org/ftp/rsync/rsync-3.0.8.tar.gz
- # tar xf rsync-3.0.8.tar.gz
- # ./configure --prefix=/usr && make && make install
- # vi /etc/rsyncd.conf
添加下面的代码到rsyncd.conf中
- uid = nobody
- gid = nobody
- use chroot = no
- strict modes = yes
- max connections = 200
- pid file = /var/run/rsyncd.pid
- lock file = /var/run/rsync.lock
- log file = /var/log/rsyncd.log
- [test]
- path = /home/
- comment = test
- read only = no
- write only = no
- ignore errors = yes
- list = yes
- uid = root
- gid = root
启动rsync服务
- # rsync --daemon
二、配置sersync2
sersync2是金山逍遥网技术支持部平台组周洋童鞋,开发的一款基于 inotify + rsync 的大量文件的多服务器自动同步程序,目前已开源,开源协议为 New BSD License,项目的下载地址:
- http://code.google.com/p/sersync/
这个配置超简单的,下载文件,解压即可
- # wget -c http://sersync.googlecode.com/files/sersync2.5_64bit_binary_stable_final.tar.gz
- # tar xf sersync2.5_64bit_binary_stable_final.tar.gz
- # cd GNU-Linux-x86
- # mkdir /etc/sersync2
- # cp confxml.xml /etc/sersync2
- # cp sersync2 /usr/bin
配置sersync2
- <sersync>
- <localpath watch="/data/bb">
- <remote ip="192.168.1.4" name="test"/>
- <remote ip="192.168.1.6" name="test"/>
- <!--<remote ip="192.168.8.40" name="tongbu"/>-->
- </localpath>
- <rsync>
- <commonParams params="-artuz"/>
- <auth start="false" users="root" passwordfile="/etc/rsync.pas"/>
- <userDefinedPort start="false" port="874"/><!-- port=874 -->
- <timeout start="false" time="100"/><!-- timeout=100 -->
- <ssh start="false"/>
- </rsync>
- <failLog path="/var/log/rsync_fail.log" 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>
表明要将同步服务器上本地的/data/bb 路径下的文件,同步到远程服务器 192.168.1.4 与 192.168.1.6上的test 模块下。
接下来,运行sersync2
# sersync2 -r -o /etc/sersync2/confxml.xml
-r的意义
- -r 在开启实时监控之前对同步服务器目录与远程目标机目录进行一次整体同步
运行完了输出
- 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: /etc/sersync2/confxml.xml
- daemon thread num: 10
- parse xml config file
- host ip : localhost host port: 8008
- daemon start,sersync run behind the console
- config xml parse success
- please set /etc/rsyncd.conf max connections=0 Manually
- sersync working thread 112 = 1(primary thread) + 1(fail retry thread) + 10(daemon sub threads)
- Max threads numbers is: 32 = 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 /data/bb && rsync -artuz -R --delete ./ 192.168.1.4::test >/dev/null 2>&1
- run the sersync:
- watch path is: /data/bb
sersync2的参数
- sersync2 -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
- ________________________________________________________________
索性一次性运行
- # sersync2 -r -d -o /etc/sersync2/confxml.xml
其他功能待研究中
