实时同步lsyncd

要求rsync >= 3.1

rsync --version
systemctl status rsyncd

1.安装lsyncd
yum install -y lsyncd
lsyncd --version
2.创建日志文件
mkdir /var/log/lsyncd
touch /var/log/lsyncd/lsyncd.{log,status}
3.创建配置文件
mkdir -p /etc/lsyncd
vim /etc/lsyncd.conf
4.配置文件写入以下内容：
settings {
        logfile = "/var/log/lsyncd/lsyncd.log",
        statusFile = "/var/log/lsyncd/lsyncd.status",
		pidfile = "/var/run/lsyncd.pid",
		statusInterval = 1,
		nodaemon = false,
		maxProcesses = 1,
		maxDelays = 1,		
}
#本地同步 
sync {
        default.rsync,
        source = "/data/source",
        target = "/data/target",
    }
#rsync+ssh远程目录同步，需要免key登录
sync {
   default.rsyncssh,
   source="/data/source",
   delete = true,
   host="root@192.168.15.6",
   targetdir="/data/target",
   -- 忽略文件路径规则，可用table也可用外部配置文件
   -- excludeFrom = "/etc/lsyncd_exclude.lst",
   exclude={
        ".txt"            --需排除的文件
    },
   rsync = {
       binary = "/usr/bin/rsync", --需先安装好rsync
       archive = true,            --归档
       compress = false,          --压缩
       owner = true,              --属主
       perms = true,              --权限
       whole_file = false
       },
   ssh = {
       port = 22
   }
}
#rsync-daemon模式，需要配置好rsync的服务端
sync {
    default.rsync,
    source = "/data/source",
    target = "rsync_user@192.168.15.6::backup",
    exclude = { ".bak*" },
	delete = true,
    delay = 30,
    init = true,
    rsync = {
        binary = "/usr/bin/rsync",
        archive = true,
        compress = true,
        verbose = true,
        perms = true,
        password_file = "/etc/rsync.password", 
        _extra = {"--bwlimit=200"}    --bwlimit 限速，单位kb/s,
    }
}
5.启动lsyncd服务
lsyncd -nodaemon /etc/lsyncd.conf
systemctl restart lsyncd
systemctl enable lsyncd
6.rsync-daemon模式
#lsyncd端配置
vim /etc/rsync.password
echo "1234567" > /etc/rsync.password
chmod 600 /etc/rsync.password
#rsync服务端配置
安装rsync
vim /etc/rsyncd.conf
uid = root
gid = root
use chroot = no
strict modes = no
max connections = 100
charset=utf8
log file = /var/log/rsyncd.log
pid file = /var/run/rsyncd.pid
hosts allow = 192.168.15.20
hosts deny = *
[backup]
path = /data/target/
read only = no
write only = no
list = no
exclude = .svn/
dont compress = *.gz *.tgz *.zip *.z *.bz2 *.tbz
auth users = rsync_user
secrets file = /etc/rsync/rsync.pass

echo 'rsync_user:123456'>/etc/rsync/rsync.pass
chmod 600 /etc/rsync/rsync.pass

#rsync用法
rsync -auv --password-file=/etc/rsync.password --delete /data/source/ rsync_user@192.168.15.6::backup
#lsyncd delete -- 用法如下
