inotify配置是創建在rsync服務基礎上的配置過程linux
操做系統git
| 主機名 | 網卡eth0 | 默認網關 | 用途 |
| root@58server1 | 192.168.1.111 | 192.168.1.1 | Rsync服務端 |
| root@58client | 192.168.1.121 | 192.168.1.1 | Rsync 節點 |
子網掩碼均爲255.255.255.0github
具體需求：bash
要求在58server1上以rsync守護進程的方式部署rsync服務，使得root@58client的 rsync節點客戶端主機把/data/數據目錄和/data0/www目錄中的數據同步到58server1 rsync服務端中post
1、在配置inotify前己經把root@58server1 Rsync服務端的rsync服務部置好測試

2、開始安裝ui
在安裝inotify-tools前請先確認你的linux內核是否達到了2.6.13，而且在編譯時開啓CONFIG_INOTIFY選項，spa
1） 查看當前系統是否支持inotify操作系統

[root@58client ~]# uname -r

[root@58client ~]# ls -l /proc/sys/fs/inotify/
total 0
-rw-r--r-- 1 root root 0 May 4 22:33 max_queued_events

-rw-r--r-- 1 root root 0 May 4 22:33 max_user_watches
|
#顯示這三個文件則證實支持3d
2）下載inotify源碼包

[root@58client ~]# mkdir /home/Mr.Xing/tools/ -p
[root@58client ~]# cd /home/Mr.Xing/tools/
[root@58client tools]# wget http://github.com/downloads/rvoicilas/inotify-tools/inotify-tools-3.14.tar.gz

3）編譯安裝inotfiy

[root@58client tools]# ls
inotify-tools-3.14.tar.gz
[root@58client tools]# tar zxf inotify-tools-3.14.tar.gz
[root@58client tools]# cd inotify-tools-3.14
[root@58client inotify-tools-3.14]# ./configure --prefix=/usr/local/inotify-tools-3.14
[root@58client inotify-tools-3.14]# make
[root@58client inotify-tools-3.14]# make install
[root@58client inotify-tools-3.14]# cd ..
[root@58client tools]# ln -s /usr/local/inotify-tools-3.14/ /usr/local/inotfiy
[root@58client tools]# ls -l /usr/local/|grep inotify
lrwxrwxrwx 1 root root 30 May 4 22:42 inotfiy -> /usr/local/inotify-tools-3.14/
drwxr-xr-x 6 root root 4096 May 4 22:41 inotify-tools-3.14
|
參數：
--prefix=PATH 指定編譯安裝的路徑
提示：更多的編譯參數能夠使用./configure –h 查看，編譯成功後會生成4個目錄，
小軟件通常規範安裝到同一個目錄，通常爲/usr/local中
創建一個軟連接
進入安裝inotify的目錄

4） 編寫inotify實時監控腳本 編寫兩個腳本，分別對應所共享的兩個目錄
如本例子，咱們編寫兩個腳本分別爲 data_inotify.sh 和www_inotify.sh
開始編寫inotify腳本

[root@58client scripts]# dos2unix data_inotify.sh

分別運行兩個腳本:
