[Linux][lsyncd]CentOS7からUbunru16.04への同期

CentOS7 から Ubuntuにlsync

今回の環境

• master 10.0.0.1
  — CentOS6
• slave 10.0.0.2
  — Ubuntu 16.04

master

install

GITから持ってくるのがちょっと面倒だったので、RPMForgeを利用してパッケージのインストール
rpmforgeの最新版は適宜変わるので、最新版を持ってくること
http://repoforge.org/use/

[root@master ~]# yum install lsyncd --enablerepo=rpmforge
[root@master ~]# rpm -ivh http://repository.it4i.cz/mirrors/repoforge/redhat/el7/en/x86_64/rpmforge/RPMS/rpmforge-release-0.5.3-1.el7.rf.x86_64.rpm

コンフィグファイルの作成

[root@master ~]# vim /etc/lsyncd.conf
[root@master ~]# cat /etc/lsyncd.conf
----
-- User configuration file for lsyncd.
--
-- Simple example for default rsync.
--
settings {
        logfile    = "/var/log/lsyncd.log",
        statusFile = "/tmp/lsyncd.stat",
        statusInterval = 1,
        maxProcesses = 2,
        nodaemon     = false,
        insist       = 1,
}

sync{
        default.rsync,
        source="/home/bkup/",
        target="10.0.0.2:/home/bkup",
        rsync = {
          _extra = {  "-a" },
        }
}

Ubuntu1606の場合 (slave)

slave側は rsyncだけ入っていればOK

インストール

 root@slave:~# mkdir -p /home/bkup/
 root@slave:~# apt-get install rsync
 root@slave:~# vim /etc/rsyncd.conf
  uid = root
  gid = root
  read only = no
  log file = /var/log/rsyncd.log
  pid file = /var/run/rsyncd.pid 

  [test]
  path = /data/
  hosts allow = localhost 10.0.0.1/32
  hosts deny = *
  read only = false

起動&自動起動

root@slave:~# systemctl start rsync.service
root@slave:~# systemctl status rsync.service
