inotify配置是创建在rsync服务基础上的配置过程linux
操做系统git
| 主机名 | 网卡eth0 | 默认网关 | 用途 |
| root@58server1 | 192.168.1.111 | 192.168.1.1 | Rsync服务端 |
| root@58client | 192.168.1.121 | 192.168.1.1 | Rsync 节点 |
子网掩码均为255.255.255.0github
具体需求：bash
要求在58server1上以rsync守护进程的方式部署rsync服务，使得root@58client的 rsync节点客户端主机把/data/数据目录和/data0/www目录中的数据同步到58server1 rsync服务端中post
1、在配置inotify前己经把root@58server1 Rsync服务端的rsync服务部置好测试

2、开始安装ui
在安装inotify-tools前请先确认你的linux内核是否达到了2.6.13，而且在编译时开启CONFIG_INOTIFY选项，spa
1） 查看当前系统是否支持inotify操作系统

[root@58client ~]# uname -r
2.6.18-308.el5
[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_instances
-rw-r--r-- 1 root root 0 May 4 22:33 max_user_watches
|
#显示这三个文件则证实支持3d
2）下载inotify源码包

[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）编译安装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
|
参数：
--prefix=PATH 指定编译安装的路径
提示：更多的编译参数能够使用./configure –h 查看，编译成功后会生成4个目录，
小软件通常规范安装到同一个目录，通常为/usr/local中
创建一个软连接
进入安装inotify的目录

4） 编写inotify实时监控脚本 编写两个脚本，分别对应所共享的两个目录
如本例子，咱们编写两个脚本分别为 data_inotify.sh 和www_inotify.sh
开始编写inotify脚本

通常添加了脚本后要格式化一次脚本

[root@58client scripts]# dos2unix data_inotify.sh
dos2unix: converting file data_inotify.sh to UNIX format ..

分别运行两个脚本:
