(1).实验环境
源主机：youxi1 192.168.5.101
目的主机：youxi2 192.168.5.102
目的：实时同步数据
sersync默认端口874，rsync默认端口873
(2).实验
1）下载sersync
wegt https://sersync.googlecode.com/files/sersync2.5.4_64bit_binary_stable_final.tar.gz
或者Windows下载再上传源主机youxi1。
2）解压
[root@youxi1 ~]# ls
anaconda-ks.cfg sersync2.5.4_64bit_binary_stable_final.tar.gz
[root@youxi1 ~]# tar xvf sersync2.5.4_64bit_binary_stable_final.tar.gz //解压
GNU-Linux-x86/
GNU-Linux-x86/sersync2
GNU-Linux-x86/confxml.xml
[root@youxi1 ~]# ls
anaconda-ks.cfg GNU-Linux-x86 sersync2.5.4_64bit_binary_stable_final.tar.gz
[root@youxi1 ~]# mv GNU-Linux-x86 sersync 改名
[root@youxi1 ~]# ls
anaconda-ks.cfg sersync sersync2.5.4_64bit_binary_stable_final.tar.gz
3）在目标主机youxi2上修改/etc/rsyncd.conf配置文件，以及密码文件
[root@youxi2 ~]# cat /etc/rsyncd.conf
uid = root
gid = root
address = 192.168.5.102
port = 873
hosts allow = 192.168.5.101/24
use chroot = yes
max connections = 5
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsync.lock
log file = /var/log/rsyncd.log
motd file = /etc/rsyncd.motd
[backupwwwhtml]
path = /backup/www/html
comment = backup /www/html/
read only = false
list = yes
auth users = rsync2
secrets file = /etc/rsync.passwd
[root@youxi2 ~]# cat /etc/rsync.passwd
rsync2:102102
[root@youxi2 ~]# chmod 600 /etc/rsync.passwd
启动指定配置文件的rsync的守护进程
[root@youxi2 ~]# rsync --daemon --config=/etc/rsyncd.conf
[root@youxi2 ~]# ps aux | grep rsync
root 1478 0.0 0.0 114740 564 ? Ss 11:10 0:00 rsync --daemon --config=/etc/rsyncd.conf
root 1485 0.0 0.0 112720 980 pts/0 R+ 11:12 0:00 grep --color=auto rsync
4）源主机youxi1上修改sersync的配置文件
[root@youxi1 sersync]# vim confxml.xml
<?xml version="1.0" encoding="ISO-8859-1"?>
<head version="2.5">
<host hostip="localhost" port="8008"></host>
<debug start="false"/>
<fileSystem xfs="false"/>
<filter start="false">
<exclude expression="(.*)\.svn"></exclude>
<exclude expression="(.*)\.gz"></exclude>
<exclude expression="^info/*"></exclude>
<exclude expression="^static/*"></exclude>
</filter>
<inotify>
<createFile start="false"/>
<closeWrite start="true"/>
<moveFrom start="true"/>
<moveTo start="true"/>
<attrib start="false"/>
<modify start="false"/>
</inotify> <sersync>
<localpath watch="/www/html">
<remote ip="192.168.5.102" name="backupwwwhtml"/> //修改为目标主机IP地址和模块名
</localpath>
<rsync>
<commonParams params="-artuz"/>
<auth start="true" users="rsync2" passwordfile="/etc/rsync.passwd"/> //开启，修改用户名和密码文件地址
<userDefinedPort start="false" port="874"/><!-- port=874 -->
<timeout start="false" time="100"/><!-- timeout=100 -->
<ssh start="false"/>
</rsync>
<failLog path="/tmp/rsync_fail_log.sh" timeToExecute="60"/><!--default e
very 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>
添加密码文件
[root@youxi1 sersync]# vim /etc/rsync.passwd
102102
[root@youxi1 html]# chmod 600 /etc/rsync.passwd
5）开启源主机youxi1的sersync的守护进程
[root@youxi1 sersync]# /root/sersync/sersync2 -dro /root/sersync/confxml.xml
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: -d run as a daemon
option: -r rsync all the local files to the remote servers before the sersync work
option: -o config xml name： /root/sersync/confxml.xml
daemon thread num: 10
parse xml config file
host ip : localhost host port: 8008
daemon start，sersync run behind the console
use rsync password-file :
user is rsync2
passwordfile is /etc/rsync.passwd
config xml parse success
please set /etc/rsyncd.conf max connections=0 Manually
sersync working thread 12 = 1(primary thread) + 1(fail retry thread) + 10(daemon sub threads)
Max threads numbers is: 22 = 12(Thread pool nums) + 10(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 /www/html && rsync -artuz -R --delete ./ [email protected]::backupwwwhtml --password-file=/etc/rsync.passwd >/dev/null 2>&1
run the sersync:
watch path is: /www/html
6）测试
现在的目的主机youxi2情况如下
[root@youxi2 ~]# ls /backup/www/html/
adm crash empty gopher lib lock mail opt run tmp
cache db games kerberos local log nis preserve spool yp
对源主机youxi1的/www/html/目录下文件进行操作
[root@youxi1 sersync]# cd /www/html/
[root@youxi1 html]# ls
adm crash empty gopher lib lock mail opt run tmp
cache db games kerberos local log nis preserve spool yp
[root@youxi1 html]# rm -rf adm/
[root@youxi1 html]# touch 1.txt
[root@youxi1 html]# ls
1.txt crash empty gopher lib lock mail opt run tmp
cache db games kerberos local log nis preserve spool yp
回到目的主机查看情况
[root@youxi2 ~]# ls /backup/www/html/
1.txt crash empty gopher lib lock mail opt run tmp
cache db games kerberos local log nis preserve spool yp
