Rsync与Lsync配置手册

1)配置目标主机(需将文件同步到远程的服务器主机)
[root@node5 ~]# yum install rsync -y
[root@node5 ~]# vim /etc/rsyncd.conf
......
......
......
......
......
......

# 于最后追加如下内容
[cloud]
# 指定从服务器端同步到本地指定目录
path = /tech/cloud
hosts allow = node1.1000cc.net
hosts deny = *
list = true
uid = root
gid = root
read only = false

[root@node5 ~]# mkdir -p /tech/cloud/cloud-test
[root@node5 ~]# systemctl enable --now rsyncd

2) 源主机配置(本地主机)
[root@node1 ~]# yum install rsync -y

# 设定所要排除的目录或文件
[root@node1 ~]# vim ~/rsync-exclude.txt
cloud-test
host-list.txt

[root@node1 ~]# mkdir -pv test/cloud-test
[root@node1 ~]# touch test/host-list.txt test/a{1..5}.txt

# 将本地/root/test/目录下的文档同步至node5节点上
[root@node1 ~]# rsync -avz --delete --exclude-from=/root/rsync-exclude.txt /root/test/  node5.1000cc.net::cloud
sending incremental file list
deleting test/a.txt
./
a1.txt
a2.txt
a3.txt
a4.txt
a5.txt

sent 368 bytes  received 129 bytes  994.00 bytes/sec
total size is 0  speedup is 0.00

4) 客户端验证
[root@node5 ~]# tree /tech/cloud/
/tech/cloud/
├── a1.txt
├── a2.txt
├── a3.txt
├── a4.txt
├── a5.txt

0 directory, 5 files

5) Rsync其他操作
# 手工指定排除的文件/目录
[root@node1 ~]# rsync -avz --delete --exclude=host-list.txt /root/test/ node1.1000cc.net::cloud

# 手工指定同步的文件
[root@node1 ~]# rsync -avz --delete --include=host-list.txt --exclude=/* /root/test/ node1.1000cc.net::cloud 

# 使用文件指定同步的文件
[root@node1 ~]# vim rsync-include.txt 
host-list.txt

[root@node1 ~]# rsync -avz --delete --include-from=/root/rsync-include.txt  /root/test/ --exclude=/* node1.1000cc.net::cloud

6) 从服务器同步至指定本地目录
# 本例演示将CentOS7的源同步至本地指定目录
[root@node5 ~]# rsync -avz --progress rsync://mirrors.163.com/centos/7/ /var/www/html/

1) 完成Rsync配置并实现同步机制

2) 安装Lsyncd
[root@node1 ~]# yum --enablerepo=epel install lsyncd -y

3) 配置lsyncd
[root@node1 ~]# vim /etc/lsyncd.conf
# 注释第8行
-- sync{default.rsyncssh, source="/var/www/html", host="localhost", targetdir="/tmp/htmlcopy/"}

......
......
......
......
......
......

# 于文件最底部追加如下内容
settings{
    statusFile = "/tmp/lsyncd.stat",
    statusInterval = 1,
}
sync{
    default.rsync,
    # 监控所需要同步的目录
    source="/root/test/",
    # 同步到指定的FQDN或IP
    target="node1.1000cc.net::cloud",
    # 指定同步时所需要排除的文件
    excludeFrom="/root/rsync-exclude.txt",
}

[root@node1 ~]# systemctl enable --now lsyncd
[root@node1 ~]# touch test/a{6..8}.txt

4) 客户端测试
[root@node5 ~]# /tech/cloud/
