剛好前面用rsync+sersync做了主從數據同步,現在有新的需求了,P2P系統兩臺服務器做負載均衡,但是由於P2P會生成N多的合同,N多的數字證書,會上傳文件,所以根據現實情況需要兩臺相互同步。
感覺sersync應該能夠實現這個功能,感覺應該是能滿足要求的,接下來就部署起來了。
安裝就參照前一篇文章了,下面是具體步驟:
步驟一:規劃好需要同步的目錄
爲方便起見,兩臺服務器要同步的目錄我建成一樣的結構,/home/p2padm/
步驟二:配置好兩臺服務器的rsync(兩臺都要配置)
Centos缺省是安裝了rsync的,只是缺省沒有配置和啓動後臺進程而已,做下配置,以下是Server1的配置過程,Server2的配置過程類似,只是hosts allow要換成Server1的。
vi
/etc/rsyncd.conf
uid
= p2padm
gid = p2p
read only = no
use chroot = true
transfer logging = true
log format = %h %o %f %l %b
log file = /var/log/rsyncd.log
pid file = /var/run/rsyncd.pid
lock file=/var/run/rsyncd.lock
#hosts allow = trusted.hosts
#slp refresh = 300
max connections=30
[p2padm]
path = /home/p2padm/
comment = p2padm rsync
auth users = p2padm 同步用的用戶名
secrets file = /etc/rsyncd.secrets
hosts allow = 172.16.17.11 對方機器IP
hosts deny = 0.0.0.0/32
exclude=tmp/ log/ trc/ backup/ dump/ jboss5/ 排隊哪些文件夾下的內容不需要同步
vi
/etc/rsyncd.secrets p2padm:p2padm chmod 666 rsyncd.secrets
步驟三:下載
sersync 並配置(兩臺都要配置)
以下是Server1的配置過程,Server2的配置過程類似,只是remote
allow要換成Server1的,安裝參照前一篇,配置文件見下:
vi
confxml.xml
<?xml
version="1.0" encoding="ISO-8859-1"?>
<head version="2.5">

</localpath>
<rsync>

</rsync>

<crontab start="false" schedule="600"><!--600mins-->
<crontabfilter start="false">

<exclude expression="info/*"></exclude>
</crontabfilter>
</crontab>
<plugin start="false" name="command"/>
</sersync>
<plugin name="command">
<param prefix="/bin/sh" suffix="" ignoreError="true"/>
<!--prefix /opt/tongbu/mmm.sh suffix-->
<filter start="false">
<include expression="(.*)\.php"/>
<include expression="(.*)\.sh"/>
</filter>
</plugin>
<plugin name="socket">
<localpath watch="/opt/tongbu">
<deshost ip="192.168.138.20" port="8009"/>
</localpath>
</plugin>
<plugin name="refreshCDN">
<localpath watch="/data0/htdocs/cms.xoyo.com/site/">
<cdninfo domainname="ccms.chinacache.com" port="80" username="xxxx" passwd="xxxx"/>
<sendurl base="http://pic.xoyo.com/cms"/>
<regexurl regex="false" match="cms.xoyo.com/site([/a-zA-Z0-9]*).xoyo.com/images"/>
</localpath>
</plugin>
</head>
步驟四:啓動sersync後臺daemon程序,開始進入監控(兩臺都要運行)
啓動兩臺的rsync
/usr/bin/rsync
--daemon--config=/etc/rsyncd.conf
再啓動兩臺的sersync
/usr/local/sersync/sersync2-d
-r -o /usr/local/sersync/confxml.xml
查看同步日誌tail -f 100 /var/log/rsync.log
完成,收工,在兩臺服務器的這個目錄下建目錄,加文件,刪除文件看,是不是同步了。
當然我這配置的都是手動啓動的,可以添加到系統自動啓動運行,我就先不弄了,留點後門。
