The virtual machine network settings that are imported from the virtual machine OVF template change and the NIC changes, so the network is not available after the virtual machine starts.So to do the following few things, the network will be available:1 First look at the/etc/udev/rules.d/70-persistent-net.rules file, the ETH NIC that appears at the end of the file is the new network card established by the system, and the MAC address. Comment out the original NIC line.2 views/etc/sysconfig/networ

Reprint Please specify source: Jiq's technical BlogAfter my tests, I came to the following conclusions about session termination:The client creates a zookeeper instance to connect to the zookeeper server and sets the session timeout to 10s.(1) If the zookeeper server is forced to shut down (simulating its crash), the client immediately receives the disconnected connection disconnect event, waits half an hour, starts the zookeeper server again, the client receives the Syncconnected connection est

Sorting sometimes has to consider suffixes. This looks more natural.Refer to the previous article in CodeProject: Http://www.codeproject.com/Articles/22978/Implementing-the-NET-IComparer-interface-to-get-aThen I wrote a simple, considering that the main idea is the above article, so do not do too much explanation.
