一，lsync实时同步
-
安装部署lsync实时同步工具
yum install -y lsyncd -
编写配置文件
vim /etc/lsyncd.conf
settings {
logfile = "/var/log/lsyncd/lsyncd.log",
statusFile = "/var/log/lsyncd/lsyncd.status",
inotifyMode = "CloseWrite",
maxProcesses = 8,
}
sync {
default.rsync,
source = "/data",
target = "rsync_backup@172.16.1.41::backup",
delete= true,
exclude = { ".*" },
delay = 1,
rsync = {
binary = "/usr/bin/rsync",
archive = true,
compress = true,
verbose = true,
password_file = "/etc/rsync.password",
_extra = {"--bwlimit=200"}
}
}
- 启动服务
systemctl start lsyncd

二，sersync软件二进制部署。
接收机上的操作：
Backup服务器
1）安装rsync
[root@backup ~]# yum install rsync -y
2）配置rsync
[root@backup ~]# cat /etc/rsyncd.conf
uid = www
gid = www
port = 873
fake super = yes
use chroot = no
max connections = 200
timeout = 600
ignore errors
read only = false
list = false
auth users = rsync_backup
secrets file = /etc/rsync.passwd
log file = /var/log/rsyncd.log
#####################################
[backup]
comment = welcome to oldboyedu backup!
path = /backup
3）根据配置完成对应初始化操作
[root@backup ~]# groupadd -g 666 www
[root@backup ~]# useradd -u 666 -g666 www
[root@backup ~]# mkdir /backup /data
[root@backup ~]# chown -R www.www /backup/ /data/
[root@backup ~]# echo "rsync_backup:123456" > /etc/rsync.passwd
[root@backup ~]# chmod 600 /etc/rsync.passwd
4）重启Rsync服务
[root@backup ~]# systemctl restart rsyncd
推送源机上的操作：
NFS服务器：
1.下载并解压sersync软件包
如果大家网络不好上不去git，这里下载好的sersync二进制软件包。
https://files.cnblogs.com/files/hypj/sersync2.5.4_64bit_binary_stable_final.tar.gz
[root@nfs ~]# tar xf sersync2.5.4_64bit_binary_stable_final.tar.gz
[root@nfs ~]# mv GNU-Linux-x86/ /usr/local/sersync
2.配置confxml.xml
[root@localhost conf]# cat confxml.xml
<?xml version="1.0" encoding="ISO-8859-1"?>

3.启动
[root@nfs ~]# /usr/local/sersync/sersync2 -h
[root@nfs ~]# /usr/local/sersync/sersync2 -dro /usr/local/sersync/confxml.xml
４．重启操作如下：
killall sersync2 && sersync2 -dro /usr/local/sersync/conf/confxml.xml
（ps 无法由systemctl启动，只能手动/脚本启停，pkill sersync2，sersync2 -dro /usr/bin/xxxxx
可以通过多个配置文件实现，不同目录的备份服务)
５．配置开机启动
｀echo "rsync --daemon --config=/etc/rsyncd.conf" >> /etc/rc.d/rc.local`
｀echo "sersync2 -dro /usr/local/sersync/conf/confxml.xml" >> /etc/rc.local｀

排错经验： 首先看提示信息error
配置文件出错:
01.. 书写信息错误
02. 文件语法错误
03. 配置参数缺失
