SCVMM R2 Operations Management Two: Installing the domain controllerBlog post and we talked about what is SCVMM and some of the corresponding environmental requirements to be aware of installing SCVMM, starting with today's blog I'll show you the basic installation of SCVMM and some basic management. I'm going to talk to you today about the preparation of the SCV

After the full and incremental recovery to restore the records of the mysql-bin.000023 update will cause a primary key conflict, you can edit the mysql-bin.000023 resolved to the MySQL data file to delete the conflicting data, if more data? You can also turn off sql_log_bin. Closing Sql_log_bin will not update the Binlog log file, which will result in data loss. So at this time, the best way is to hold the library, prohibit ex

Compare with Windows to introduce Basic Linux operation methods and file management! (in pure command-line mode, why do you want to emphasize the command line?) Because at the end of the second I explained that almost all operations are done on the command line .　　　　Why do you want to compare it with Windows? because I was learning Linux when the whole brain completely without its concept, has been thinki

Introduction to File system operations and Disk Management experimentsThe file system operation of this section of the experiment is very simple and contains only a few parameters of several commands, but mastering these will also help you in the process of learning about other courses in Linux and the lab building. Because this course is positioned as a primer, as soon as possible, so there is no

SCVMM R2 Operations Management 11: Adding hyper-V clustersThe previous blog post and everyone described how to add a trusted Hyper-V host and a non-trusted Hyper-V host. But we need to know that in many cases we already have Hyper-V's high-availability environment before we go to SCVMM, so today we're going to introduce you like and add the existing Hyper-V cluster in our environment to SCVMM.Since some of

SCVMM R2 Operations Management 13: Adding resources to the VMM libraryThe previous blog post tells you how to add a library server to VMM, and in today's post you'll discuss how to add resources to the VMM library for our use.We can use the following procedure to add a file's resource (also known as a physical resource) to an existing library share in System Center 2012–virtual machine Manager (VMM), and th

The following operations are based on p4v. 1 P4 refresh all In some cases, some modifications cannot be updated in p4v in real time. In this case, p4v refresh all can be used. You can also right-click any item to find refresh-related operations. For example, if you delete or add files in the local directory, the file cannot be reflected in p4v in time. You can right-click the refresh option in the w
