多服务器实时同步方案 - 软件仓

##一、中央服务器（目标服务器）配置
####1. 安装rsync并配置
	# 安装rsync
	yum install -y rsync
	# 创建配置文件
	vi /etc/rsyncd.conf
	
---
	# /etc/rsyncd.conf 内容
	uid = root
	gid = root
	use chroot = no
	max connections = 100
	pid file = /var/run/rsyncd.pid
	lock file = /var/run/rsync.lock
	log file = /var/log/rsyncd.log

[data_sync]   # 模块名称
	path = /data/recordfile
	comment = RealTime Sync Directory
	read only = no
	auth users = rsync_user
	secrets file = /etc/rsync.passwd

---
####2. 创建密码文件
	echo "rsync_user:your_password" > /etc/rsync.passwd
	chmod 600 /etc/rsync.passwd
	
---
####3. 启动服务
	systemctl start rsyncd
	systemctl enable rsyncd
	firewall-cmd --add-port=873/tcp --permanent
	firewall-cmd --reload
	
---
##二、源服务器（需要同步的每台服务器）配置
####1. 安装lsyncd
	yum install -y epel-release
	yum install -y lsyncd
	
####2. 创建密码文件（免交互）
	echo "your_password" > /etc/rsync.passwd
	chmod 600 /etc/rsync.passwd
	
####3. 配置lsyncd
	vi /etc/lsyncd.conf

    settings {
        logfile    = "/var/log/lsyncd.log",
        statusFile = "/tmp/lsyncd.status",
        maxDelays = 5,
        maxProcesses = 3,
        insist = true,
    }
    
    sync {
        default.rsync,
        source    = "/home/kunshi/mediarecord/record/",
        target    = "rsync_user@172.16.100.12::data_sync",
        excludeFrom = "/etc/lsyncd_exclude.lst",  -- 可选排除列表
        rsync     = {
            binary = "/usr/bin/rsync",
            password_file = "/etc/rsync.passwd",
            archive = true,
            compress = true,
            verbose = true,
            perms = true,
            _extra = {
               "--bwlimit=10000",              -- 限速10MB/s
               "--chmod=D750,F644",
               "--chown=root:root",
               "--ignore-existing",
               "--exclude='oss/'"
            }
        }
    }
	
---
####4. 创建排除文件（可选）
	echo ".tmp*" > /etc/lsyncd_exclude.lst
	echo "*.log" >> /etc/lsyncd_exclude.lst
	
---
####5. 启动服务
	systemctl start lsyncd
	systemctl enable lsyncd
	
---
##三、验证同步效果
####在源服务器创建测试文件：
	touch /source/dir/test_sync.txt
---
####在中央服务器检查：
	ls /target/dir  # 应看到test_sync.txt
