Two Rhel5.6web servers, which ran Apache, the directory is/va/www/html, now want to put online web data in real-time backup to another Web server, that is, this "another Web server" as a real-time standby machine, Here I refer to the Web machine on the line as the source server, as a real-time standby server called the target serverExperimental process:Part I: Configuring the target server:#service iptables Stop#setenforce 0#yum Install httpd#service httpd Start#chkconfig--level httpd on[Email p

Load balancing with multiple Web servers to keep resources consistent on the front-end Web server can be synchronized to other from the server (read-only server) by rsync on the primary server (writable data), but not automatically for real-time synchronization. Real-time synchronization can be achieved using inotify Home server: 192.168.6.205 inotifyFrom server: 192.168.6.36 rsync 1. Configure
