Using Elasticsearch to mention the Curl tool,Curl is an open source file Transfer tool that works with URL syntax in the command line mode. Website address:https://curl.haxx.se/Because Elasticsearch provides a standard HTTP interface, we can use curl to easily access the Elasticsearch.Some of the following collections use the Curl command to manipulate Elasticsearch.First: _cat seriesThe _cat series provides a series of interfaces that query the state of the Elasticsearch cluster. You can do thi

"Sixth Quarter" I'll show you how to install a Web server this time, based on the domain environment topology in the first quarter. According to the actual enterprise Environment Web service is not only for the intranet users, but also for the external network users. So I deployed the Web server in the DMZ area, which can greatly increase the security of the intranet, the DMZ can be accessed by the internal and external network users, but it cannot access the internal and external network.1.

Two ways to Centos7.3 SQL Server backup and restoreTwo of our previous articles described the installation configuration of SQL Server under Centos7.3 and the management of using PowerShell, and today we go on to implement SQL Server backup and restore under Centos7.3 in two ways: 1. Using SSMs for backup and restore , this mode is the simplest and most convenient way to operate, 2, the use of Linux under the SQL Server features command backup, specifically see below:We created a test database i
