Lsync 同步软件的运用

2023-12-08 2 分钟阅读

公司使用智齿的机器崩了，要做数据迁移。

由三台老机器迁移到三台新kvm机器

我们需要把其中一台34.38的的东西实时同步两份，一份到30.18的glusterfs，一份到34.41的/data

同时也要注意30.18的GFS中已经有两个虚机文件，32.6和34.38的qcow2

所以lsync务必要小心，不能删除已有文件

172.18.34.38上面的lsyncd.conf如下，同步到两个目的地： 注意下面的参数：

  1. maxProcesses = 2 # 本机用于rsync的进程数

  2. delete = ‘running’ # 只删除lsync启动之后删除的文件，目的文件夹中原有的文件保存

  3. exclude = “upload” # 第二个同步中排除的目录，注意这里是匹配全路径中的部分字串，upload 可以匹配到 /data/new/chatmsg/upload/allajl.jpg，就upload目录下文件大，所以把它排除。**这里的规则是和rsync中exclude的写法不同的！！！**只取路径中的upload字串就可以排除。

----
-- User configuration file for lsyncd.
--
-- Simple example for default rsync, but executing moves through on the target.
--
-- For more examples, see /usr/share/doc/lsyncd*/examples/
-- 
-- sync{default.rsyncssh, source="/var/www/html", host="localhost", targetdir="/tmp/htmlcopy/"}

settings {
    logfile = "/var/log/lsyncd/lsyncd.log",
    statusFile = "/var/log/lsyncd/lsyncd-status.log",
    statusInterval = 5,
    maxProcesses = 2
}

sync {
    default.rsync,
    source = "/data/new",
    target = "172.18.30.18::new",
    delete = 'running',
    delay = 5,
    rsync     = {
        binary = "/usr/bin/rsync",
        archive = true,
        compress = false,
        verbose   = true
    }
}

sync {
    default.rsync,
    source = "/data",
    target = "172.18.34.41::new",
    delete = 'running',
    exclude = "upload",
    delay = 5,
    rsync     = {
        binary = "/usr/bin/rsync",
        archive = true,
        compress = false,
        verbose   = true
    }
}
fallback

对端rsyncd的配置如下：

# cat /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
uid = root
gid = root
use chroot = no
max connections = 200
timeout = 300
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsync.lock
log file = /var/log/rsyncd.log

[new]
path = /root
ignore errors
read only = false
list = false
hosts allow = 172.18.34.38
hosts deny = 0.0.0.0/32
fallback

这是个极端强力的工具，墙裂推荐！。
