MySQL Utilities is a set of command line utility tools based on the python library written in Python language, and relies on python 2.6. This tool provides some tools commonly used in MySQL database operation and maintenance projects, such as cloning, copying, comparison, difference, export, import, installation, configuration, indexing, disk viewing, etc. With this tool kit, you can be like those miraculous doctors who can do a test or a CT scan regardless of whether they are serious or minor. You can also be Hua Tuo. MySQL Utilities provides software packages for various platforms. If you do not find the package corresponding to your platform, you can compile and install it through the source code. This article mainly describes the installation of MySQL Utilities and a preliminary description of each working function.
