sersync+rsync做实时同步

时间：2021-11-21 01:27:19

(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 ./ rsync2@192.168.5.102::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
