rsync+inotify實現實時數據同步

本例中是通過inotify監控客戶端的目錄文件是否發生變化，如發生變化實時的同步到服務端

主機

client 17X.19.23.24
server 1X.237.150.72

監控client端目錄

/export/jenkins_data
/export/yangfan

client端

• 安裝文件監控工具inotify-tools
  [root@A01-R08-I23-24 Shell]# yum install inotify-tools
• 安裝rsync
  [root@A01-R08-I23-24 Shell]# yum install rsync
• 配置rsync客戶端密碼 （此密碼是rsync互相通信的密碼，與系統登錄密碼不是一回事）
  [root@A01-R08-I23-24 Shell]# cat /etc/rsync.password
  2egseZjPc7jJxwa#
• 配置密碼文件權限
  [root@A01-R08-I23-24 Shell]# chmod 600 /etc/rsync.password
• 配置監控腳本 （本例中是監控兩個目錄，所以寫了兩個監控腳本，之前嘗試一個腳本中監控兩個目錄會有問題）
  [root@A01-R08-I23-24 Shell]# cat inotify-an.sh
  #!/bin/bash
  /usr/bin/inotifywait -mrq --timefmt ‘%d/%m/%y %H:%M’ --format ‘%T %w%f’ -e modify,delete,create,attrib /export/yangfan | while read file
  do
  /usr/bin/rsync -vzrtopg --delete --progress /export/yangfan/ [email protected]::ansible-data --password-file=/etc/rsync.password
  echo “KaTeX parse error: Expected 'EOF', got '&' at position 46: …og/rsync.log 2>&̲1 done [root@…{files} was rsynced” >> /var/log/rsync.log 2>&1
  done
• 啓動監控腳本
  [root@A01-R08-I23-24 Shell]# nohup sh inotify-an.sh &
  [root@A01-R08-I23-24 Shell]# nohup sh inotify-jen.sh &

server端

• 安裝rsync
  [root@A01-R15-I150-72-4000255 ~]# yum install rsync
• 修改rsync配置文件
  [root@A01-R15-I150-72-4000255 ~]# cat /etc/rsyncd.conf
  uid = 0
  gid = 0
  use chroot = no
  max connections = 0
  timeout = 300

• 配置密碼文件 （服務端密碼文件裏格式必須是 用戶名:密碼）
  [root@A01-R15-I150-72-4000255 ~]# cat /etc/rsync.password
  root:2egseZjPc7jJxwa#
• 配置文件權限
  [root@A01-R15-I150-72-4000255 ~]# chmod 600 /etc/rsyncd.conf
  [root@A01-R15-I150-72-4000255 ~]# chmod 600 /etc/rsync.password
