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
[backup]
path = /data/www
comment = backup
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?
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。
