execute: Use MySQL; Select Host,user,password from user; You can see that the ITBC user that you just created is already in the user table. The Host field represents the hosts that are logged on, their values can be IP, or the host name is available, and changing the value of the host field to% means that the ITBC user can log on to the MySQL server on any client machine, and it is recommended that you set it to% at development time.Update user Set host = '% ' where user = ' ITB

By default, Mysql cannot be accessed through a remote machine. You can enable remote access through the following configuration. My Mysql environment is ubuntu + mysql5 1. Modify/etc/mysql/my. conf, bind-address, and specify as the actual IP address of the Local Machine. After modifying your my. con, it looks like the following: [Mysqld] # # * Basic Settings # Default-character-set = utf8 Default-storage-engine = INNODB Bind-address = 192.168.1.107 User = mysql Pid-file =/var/run/mysqld. pid Soc

by copying files in different environments. The tools and usage modes in the team should be unified and best practice training should be given. 2. Use a better project to build the platform.Replace the existing ant with Maven. This has been carefully researched and compared, and I have the opportunity to detail it in subsequent articles. Maven has the biggest advantage over ant. It looks at the problem from the management point of view with Maven, while ant is mainly used to automate repetitive

At present, the company requires all integration testing and end-to-end testing to collect code coverage, Icoco to help testers do a good job.Figure2Icoco Basic Work Flow1.

ensure code quality. From a practical point of view, the automated code Review is more static analysis of the codes, by scanning the code and contrasting the rules that are produced to produce the desired results. The desired result can be a quantitative quality report for the project as a whole, or a warning to be displayed in Xcode??。 This depends on what role the user is in.In practice, there are generally two roles that will focus on the results-engineers and management. Engineers need to b

What is ping? Often a netizen asked me this question, in fact, the word ping originally originated from the sonar detection system, intended to refer to the pulse signal from the sonar equipment. In the development of the Internet, the process of detecting the connectivity between two nodes in the network is very similar to the sonar detection process, so the nam

default is the size of the system memory, and of course you can use-xx:maxmetaspacesize to set the maximum size, which is the same as the previous Max perm size. At the same time, when we set the-xx:maxmetaspacesize parameter, we can also implement the problem of Oom caused by Max Perm. We can achieve the famed OOM error by setting the Maxmetaspacesize argument to JVM and running of the sample program Prov IDed.
