rsync + sersync 实现实时数据同步

一、环境：

主机1：youzhuan-bak     centos 7.2 

主机2:youzhuan-online   centos 7.2 

二、部署过程：

youzhuan-bak ：

[[email protected] ~]#  yum install   rsync -y 

[[email protected] ~]# rsync --daemon

[[email protected] ~]# netstat -an | grep 873

[[email protected] ~]# cat /etc/rsyncd.conf                                        rsync配置文件修改
uid = nobody
gid = nobody
use chroot = yes
address = 0.0.0.0
port 873
log file = /var/log/rsyncd.log
pid file = /var/run/rsyncd.pid
hosts allow = 172.24.119.202
[@R_197_11442@kup]
path = /data/www
comment = @R_197_11442@kup
read only = false
auth users = liang 
secrets file = /etc/rsyncd.pwd

[[email protected] ~]# cat /etc/rsyncd.pwd        增加秘钥文件
liang:m2i3sc

[[email protected] ~]# chmod 600 /etc/rsyncd.pwd         权限必须为 600

[[email protected] ~]# ll /etc/rsyncd.pwd
-rw------- 1 root root 13 Mar 29 21:18 /etc/rsyncd.pwd

youzhuan-online ： 配置  sersync 

下载安装包：  sersync2.5.4_64biT_Binary_stable_final.tar.gz

[[email protected] local]# tar -xf sersync2.5.4_64biT_Binary_stable_final.tar.gz 

[[email protected] localt]# mv GNU-Linux-x86/   sersync

[[email protected] local]# cd sersync

[[email protected] sersync]# cp confxml.xml confxml.xml.bak

[[email protected] sersync]# vim confxml.xml

[[email protected] sersync]# cat /etc/liang.passwd @H_730_35@m2i3sc

[[email protected] sersync]# chmod 600  /etc/liang.passwd 

[[email protected] sersync]# ll /etc/liang.passwd 
-rw------- 1 root root 7 Mar 29 21:19 /etc/liang.passwd

[[email protected] sersync]#  /usr/local/sersync/sersync2 -d -r -o /usr/local/sersync/confxml.xml

测试 ：

[[email protected] sersync]# cd /data/www/

[[email protected] www]# mkdir 999

在 youzhuan-bak上验证：

删除后也会实时同步，验证成功。
