In MySQL multi-instance enablement, many environments choose to use Mysqld_multi to manage multiple instances, but unfortunately, after MySQL 5.6,Mysqld_mutli can't turn MySQL off. The approach to this problem is first confirmed:Mysqladmin-h127.0.0.1-p3307-umdev-p shutdownOrMysqladmin-s/tmp/mysql3307.sock-umdev-p shutdownWork is fine.To create a user:Create user ' mdev ' @ ' localhost ' identified by ' mdev4admin ';Grant Shutdown on *. * to ' mdev ' @ ' localhost ';Luckily, Mysqld_multi is

hang and report shutdown:waiting for active calls to complete.After a long wait, do a review just for example the following process, try the kill arc0 process. Pmon process terminates the instance (equivalent to shutdown ABORT), fortunately is the shutdown before the completion of the confirmation transaction, switching redo/checkpoint, and so on, all normal startup.= = "In such cases, it is recommended to switch logfile several times before shutdown immediate, and to perform checkpoints to ens

SELinux, an abbreviation of security-enhanced Linux, are a Security enhancement to the Linux operating system. It is a labeling system, blocks many system functions in its default configuration.SELinux are very useful for some users, but due to their administrative overhead, you could be better off simply disabling it. The time spent adding rules and updating permissions on SELinux versus the added security benefit could not be worth it.First check if SELinux is disabled or enabled:sestatusIf Th

A strange phenomenon was found in the development of a program based on rtmp chat.Under Windows, when we perform closesocket operations, the blocked recv immediately returns-1.And under Linux, when we do the close operation, the blocked Recv will not return immediately. Later on the Internet a search found a lot of things like this phenomenon, the general meaning should beWhen the socket passive is close, i

. Net memory recycling and Dispose, Close, Finalize MethodsI. net objects are generally used in three situations ﹕1. Create an object2. Objects used3. Release objects2. Create an object1. There are two steps to create an object: variable type declaration and initialization object2. Variable type declaration (declare), such ﹕ Copy codeThe Code is as follows: FileStream fs This line of code will create a variable named fs in the current variable scope s

In Linux C network programming, there are two methods to close a connected network communication: the close function and the shutdown function. Their function prototypes are: 1 #include 2 int close(intsockfd) 3 // Return: 0 -- successful, 1 -- failed 4 5 #include 6

Dispose, you have to create it again.and close (), you can also open (),And after Dispose, the object does not exist, it can not open ()Dispose is for the object itself, and close is for connection to the databaseOthers are misleading ...Here are the relevant points of knowledge:1.SqlConnection conn = new SqlConnection (strconnection), if the original connection is closed, when a new connection needs to be

One of the great conveniences of using the QT editing interface is the fact that QT has a rich, full range of classes and function functions that programmers can simply invoke in the process of editing the program. For a window close operation, here is a common three slots, that is, quit (), exit (), and Close (). The code editing of the System prompt dialog box is first explained when the window exits. To
