Server 2 - MySQL #1 Lab

Transcription

1 Server-Configuration-2-MySQL-1-HW.docx CSCI 2320 Initials P a g e 1 If this lab is an Individual assignment, you must do all coded programs on your own. You may ask others for help on the language syntax, but you must organize and present your own logical solution to the problem. No lab is complete until the student submits the signed pledge form associated with that lab. I realize that no coded programs will be graded until I turn in the sign & pledge form associated with that program; any late penalties will continue to compound until the pledge form is submitted. If this lab is a team assignment, both team members may share logic as they program side by side on their own computers. Each person must type all of his/her own code as part of the learning process. Team assignments are never to be You do this portion and I ll do that portion or You do this lab and I ll do the next lab. Some of the lab assignments will have short answer questions. These short answer questions will be spot checked and graded for completion, but not checked for accuracy. I encourage you to get into a study group to help each other prepare for exams, quizzes, etc. Once these labs are graded and returned, I encourage you to compare answers with another class member, in your study group, who has also had the lab graded and returned. I/We realize that the penalty for turning in work that is not my own, or assisting others in doing so, can range from an "F" in the class to dismissal from Trinity University. I realize that it is a violation of academic integrity to share any portion of this lab with any person (outside my 3343 team & professor)! Print Name Time Required =. Hrs. Signature (pledged) Server 2 - MySQL #1 Lab Individual/Duo Lab 35 Points In a Duo Lab, Two Class Members May Sit Side By Side And Work Through The Lab On Two Different Computers You May Choose To Help Each Other! You May Share Techniques! You May Show You re your Team Mate Your Code But Each Person Is To Do All Of Their Own Typing & Enter All Of Their Own Command. Each Person Is To Sign/Pledge & Submit Their Own Pledge Form. You May Enter Your Solutions Into The Word Document & Print If Doing This Lab Individually! Complete Windows-Database-Server-Installation-2 Sign Off On The Items Below As You Complete The Tutorial Above 1] {Initial/Pledge} I successfully installed the Rapid Environment Editor on my system. I have successfully used it to add the MySQL path to my Server. 2] {Initial/Pledge} I can successfully log into MySQL (to my Server) without entering the Path. 3] {Initial/Pledge} I can successfully use MySQL Workbench, on my server, to Access the MySQL database. 4] {Initial/Pledge} The taskbar, on my server, includes the items shown below. 5] {Initial/Pledge} From a remote system, I can now store/retrieve data from the Share folder on my server. You will be asked to figure out how to use MySQL Workbench to create a database, create an account, and assign some privileges. You may watch videos for help. You may ask your team mates for help.

2 Server-Configuration-2-MySQL-1-HW.docx CSCI 2320 Initials P a g e 2 1] {Initial/Pledge} I have used MySQL Workbench to create a standard user, called JohnDoe I make the Password = trinity 2] {Initial/Pledge} "Schema" is a synonym for "Database". I have used MySQL to create a Database, called Test1

3 Server-Configuration-2-MySQL-1-HW.docx CSCI 2320 Initials P a g e 3 3] {Initial/Pledge} I have used MySQL to configure user JohnDoe as an administrator on only Database test1 see the screen captures above. 4] {Initial/Pledge} "Schema" is a synonym for "Database". I have used MySQL to create a Database, called Library1

4 Server-Configuration-2-MySQL-1-HW.docx CSCI 2320 Initials P a g e 4 5] {Initial/Pledge} With the Command Prompt, I can use my JohnDoe account to login successfully. It appears that JohnDoe can also Use Test1 6] {Initial/Pledge} With the Command Prompt, I can use my JohnDoe account to login successfully. It appears that JohnDoe can not Use Library1 7] {Initial/Pledge} I have watched the video: this video will answer some of the SQL Question You may have to refer to your CSCI 2320 notes or use google to find the answers to some of the problems below. Run Query Native Passwords 1] {Initial/Pledge} I have created localhost & % ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'trinity' ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY 'trinity' ALTER USER 'JohnDoe'@'localhost' IDENTIFIED WITH mysql_native_password BY 'trinity' ALTER USER 'JohnDoe'@'%' IDENTIFIED WITH mysql_native_password BY 'trinity' 2] {Initial/Pledge} I have run the scripts above. The new MySQL has some issues with Native Passwords; these sometimes create issues with some of the support tools. Run the Queries above substitute your password.
