Lsync的多源目录，多目标目录的实时同步实践

Lsync的多源目录，多目标目录的实时同步实践

1. 效果图解：

2.示例

BACKUP（10.0.0.41）

• 安装rsync

  [root@backup]# yum install rsync -y

• 配置

  [root@backup /usr/local/sersync]# vim /etc/rsyncd.conf

  uid = www
  gid = www
  port = 873
  fake super = yes
  use chroot = no
  max connections = 200
  timeout = 600
  ignore errors
  read only = false
  list = false
  auth users = rsync_backup
  secrets file = /etc/rsync.passwd
  log file = /var/log/rsyncd.log
  #####################################
  [backup]
  comment = welcome to oldboyedu backup!
  path = /bdata
  
  [backup1]
  comment =  welcome to oldboyedu backup1!
  path = /bdata1
  

• 创建配置文件对应的文件和目录

  [root@backup ]# groupadd -g666 www

  [root@backup ]# useradd -g666 -u666 www

  [root@backup ]# mkdir /bdata /bdata1

  [root@backup ]# chown -R www. /bdata

  [root@backup ]# chown -R www. /bdata1

• 启动

  [root@backup ]# systemctl restart rsyncd

  [root@backup ]# netstat -lntp | grep 873
  tcp 0 0 0.0.0.0:873 0.0.0.0:* LISTEN 9305/rsync

NFS（10.0.0.31）

• 安装lsync实时同步服务

  yum install lsyncd  -y 
  

• 配置lsync实时同步服务

• [root@nfs01 /data1]# cat /etc/lsyncd.conf

  -- sync{default.rsyncssh, source="/data /data1", host="nfs01", targetdir="backup01 ::backup  ::backup1"}
  settings {
      logfile      = "/var/log/lsyncd/lsyncd.log",
      statusFile   = "/var/log/lsyncd/lsyncd.status",
      inotifyMode  = "CloseWrite",
      maxProcesses = 1000,
      maxDelays    = 10,
      }
  sync {
      default.rsync,
      source    = "/data",
      target    = "rsync_backup@172.16.1.41::backup",
      delay     = 1,
      delete    = true,
      rsync     = {
          binary    = "/usr/bin/rsync",
          password_file = "/etc/rsync.pass",
          archive   = true,
          compress = false,
          verbose   = true
          }
      }
  sync {
      default.rsync,
      source    = "/data1",
      target    = "rsync_backup@172.16.1.41::backup1",
      delay     = 1,
      delete    = true,
      rsync     = {
          binary    = "/usr/bin/rsync",
          password_file = "/etc/rsync.pass",
          archive   = true,
          compress = false,
          verbose   = true
          }
      }
  

• 创建对应目录并授权

  mkdir /data /data1

  chown -R www. /data

  chown -R www. /data1

• 启动

  [root@nfs01 ~]# systemctl  start lsyncd
  [root@nfs01 ~]# systemctl  status  lsyncd
  ● lsyncd.service - Live Syncing (Mirror) Daemon

• 检验：nfs /data1目录实时同步backup01server

nfs /data1实时同步到backup01server
