二、rsync+sersync 实现数据实时同步

一、rsync部署

服务器：source 192.168.58.130 （进行数据备份的主机）
客户端：targetpc 192.168.58.131 （备份存储的主机）

push推数据

1、编写rsync配置文件

#192.168.58.131
# 在客户端上编写rsync配置文件，创建一个存放备份的同步目录
[root@targetpc ~]# vim /etc/rsyncd.conf 
# /etc/rsyncd: configuration file for rsync daemon mode
# See rsyncd.conf man page for more options.
# configuration example:
# uid = nobody
# gid = nobody
# use chroot = yes
# max connections = 4
# pid file = /var/run/rsyncd.pid
# exclude = lost+found/
# transfer logging = yes
# timeout = 900
# ignore nonreadable = yes
# dont compress   = *.gz *.tgz *.zip *.z *.Z *.rpm *.deb *.bz2
# [ftp]
#        path = /home/ftp
#        comment = ftp export area


#在这些内容后面加上下面的内容

#加上
port=873
address = 192.168.58.131
uid = root
gid = root
use chroot = yes
max connections = 4
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsync.lock
log file = /var/log/rsyncd.log
motd file = /etc/rsyncd.motd
hosts allow = 192.168.58.0/24
[data]
path = /data/backup
comment = bakcup data
read only = false
list = yes
auth users = rsyncuser
secrets file = /etc/rsync.passwd

#192.168.58.131
# 创建密码文件，格式   用户名:密码
# 设置密码文件权限为600或者700
[root@targetpc ~]# touch /etc/rsync.passwd
[root@targetpc ~]# vim /etc/rsync.passwd 
rsyncuser:123456
[root@targetpc ~]# chmod 600 /etc/rsync.passwd

#192.168.58.131
# 创建欢迎信息文件
[root@targetpc ~]# echo "Welcome to Backup Server" > /etc/rsyncd.motd

[root@targetpc ~]# systemctl start rsyncd
[root@targetpc ~]# mkdir -p /data/backup
[root@targetpc ~]# cd /data/backup

2、备份测试

#192.168.58.130
[root@source ~]# mkdir /data
[root@source ~]# cd /data
[root@source data]# touch 1.txt
[root@source data]# mkdir aaa
[root@source data]# rsync -avz /data/* rsyncuser@192.168.58.131::data

[root@source data]# touch 2.txt
[root@source data]# ls
1.txt  2.txt  aaa
[root@source data]# rsync -avz /data/* rsyncuser@192.168.58.131::data
Welcome to Backup Server

3、检验结果

#192.168.58.131
[root@targetpc backup]# ls
1.txt  2.txt  aaa


[root@targetpc backup]# touch 3.txt
[root@targetpc backup]# ls
1.txt  2.txt  3.txt  aaa

#192.168.58.130
[root@source data]# rsync -avz --delete /data/ rsyncuser@192.168.58.131::data
Welcome to Backup Server
