Real-time synchronization of Linux and Windows system files

Real-time synchronization of multiple servers, Linux and Windows system files using software Rsync and Inotify Real-time synchronization of files between two Linux hosts Host A: 192.168.254.201 Host B: 192.168.254.202 Experimental purpose, implemented on host B Make changes, real-time synchronization on host A. 1.1 Configuration on host A 1.1.1 Create a folder to be synchronized Mkdir /opt/rsync 1.1.2 Install Rsync Emerge rsync I use Gentoo, it is installed by default, and the configuration file is in /etc. /rsyncd.conf 1.1.3 Modify the configuration file Nano –w /etc/rsyncd.conf # Globel setting uid = root gid = root use chroot =no max connectiongs = 10 pid file = /var/run/rsyncd.pid lock file = /var/run/rsync.lock log file = /var/log/rsync.og # Folder Setting,Permit add more folder [images] path = /opt/image/read only = no auth users = rsyncuser secrets file = /Etc/rsyncd.secrets 1.1.4 Write verification file Nano –w /etc/rsyncd.secrets rsyncuser:Password01

IN_ACCESS, ie the file is accessed

IN_MODIFY, the file is written IN_ATTRIB, the file attributes are modified, such as chmod, chown, touch, etc. IN_CLOSE_WRITE, the writable file is Close IN_CLOSE_NOWRITE, the non-writable file is closed IN_OPEN, the file is opened by IN_MOVED_FROM, the file is removed, such as mv IN_MOVED_TO, the file is moved, such as mv, cp IN_CREATE, create a new file IN_DELETE, the file is deleted, such as rm IN_DELETE_SELF, self-delete , that is, an executable file deletes itself when executing IN_MOVE_SELF, self-moving, that is, an executable file moves itself IN_UNMOUNT during execution, the host file system is umount IN_CLOSE, the file is closed, equivalent to (IN_CLOSE_WRITE
