MySQL 5.1 installation and configuration Diagram

1. Install mysql5.1 Open the downloaded installation file and the following page is displayed:   Start the MySQL Installation Wizard and click "Next" to continue   Select the installation type, which has three options: "typical (default)", "complete (complete)", and "Custom (custom)". Select "Custom ", there are more options to familiarize yourself with the installation process. Click "MySQL Server" and select "this feature, and all subfeatures, will be Installed on local hard drive. ", that is," This part and its sub-parts are all installed on the local hard disk ". Click "change..." to manually specify the installation directory.   Fill in the installation directory, such as "F: MySQL", and do not place it in the same partition as the operating system. This prevents data from being cleared during system backup and restoration. Press "OK" to continue.   Confirm the previous settings. If there is an error, press "back" to return the redo. Click "Install" to start installation.   Installing. Please wait until the following interface appears. Click "Next" to continue. The following page is displayed.   Now that the software has been installed, the above interface appears. Here is a good function. The MySQL Configuration Wizard does not need to be the same as before, Manually configure my. ini in a mess, tick the one before "configure the MySQL server now", and click "finish ". Install the software and start the MySQL Configuration Wizard. Ii. Configure MySQL Server Click "finsh". The following page is displayed. The MySQL Server Configuration Wizard starts.   Click "Next" to display the following interface,   Select the configuration method, "detailed configuration (manual precise configuration)", and "standard configuration". Select "detailed configuration" to familiarize yourself with the configuration process.     Select the server type, "Developer machine (development and testing class, MySQL occupies a small amount of resources)", "server machine (server type, MySQL occupies a large amount of resources) "," dedicated MySQL server machine (dedicated database server, MySQL occupies all available resources) ", you choose according to your own type, generally choose" server machine ", not too little, it will not be full.     Select the general purpose of the MySQL database, "multifunctional database (Universal multi-function type, good)", "transactional database only (server type, dedicated to transaction processing, General) "," non-transactional database only (non-transaction processing type, relatively simple, mainly used for monitoring and recording, the support for MyISAM data types is limited to non-transactional ), I chose it with my own purpose. Here I select "transactional database only" and press "Next" to continue.     Configure InnoDB tablespace to select a bucket for the InnoDB database file. Location: select the same location during reinstallation. Otherwise, the database may be damaged. Of course, it is okay to back up the database. . I have not modified it here. Use the default position and press "Next" to continue.     Select the average MySQL access volume of your website and the number of connections at the same time. For example, "demo-support (DSS)/OLAP (about 20 connections)" and "online transaction processing (OLTP) (about 500) "and" manual setting (manually set, enter a number by yourself) ". Here I select" online transaction processing (OLTP) "and my server, it should be enough. Press "Next" to continue.     Whether to enable TCP/IP connection and set the port. If it is not enabled, you can only access the MySQL database on your own machine. Enable in, tick the preceding port number: 3306. on this page, you can also select enable strict mode ), in this way, MySQL will not allow small syntax errors. If you are a newbie, I suggest you cancel the standard mode to reduce the trouble. However, if you are familiar with MySQL, try to use the standard mode because it can reduce the possibility of harmful data entering the database. There is also a "add firewall exception..." setting for the firewall ......" Select to add the listening port of the MySQL service as the Windows Firewall exception to avoid firewall blocking. Press "Next" to continue.     Note: If you want to use the data of the original database, it is best to determine the encoding used by the original database. If the encoding set here is different from the encoding of the original database data, garbled characters may occur during use.   This is very important. It is to set the default MySQL database language encoding. The first is the Spanish encoding, and the second is the multi-byte encoding. General utf8 encoding is not our general encoding. Here we select the third encoding, and then select or enter "GBK" in character set ", Of course, you can also use "gb2312", the difference is that the GBK font size is large, including all the Chinese characters of gb2312, and added traditional Chinese characters, And other messy words-when using MySQL, run the "set names GBK;" command before executing the data operation command (just run it once, and the GBK can be replaced with other values, depending on the settings here), you can use Chinese characters (or other texts) normally. Otherwise, Chinese characters cannot be displayed normally. Press "Next" to continue.   Select whether to install MYSQL as a Windows service, you can also specify the service name (service ID name), whether Add the bin directory to the Windows path (after adding the directory, you can directly use the file in the bin without specifying the directory name, such After mysql.exe-uusername-ppassword###, the complete address of mysql.exe is displayed, which is very convenient.) I checked all the items here and kept the service name unchanged. Press "Next" to continue.     This step asks if you want to change the default root user (Super Management) password (blank by default). If you want to change the "New Root Password", enter the new password here (if re-installed, you have already set a password. Changing the password may cause errors. leave it blank and remove the check box before "modify Security Settings". After the installation and configuration are complete, change the password separately ), "Confirm (re-enter)" is entered again to prevent errors. "Enable root access from remotemachines (whether to allow root users to log on to other machines. If you want security, do not check it. If you want convenience, check it )". Finally, "Create an anonymous account (create an anonymous user, and the anonymous user can connect to the database, and cannot operate data, including queries)" is not checked. The settings are complete, press "Next" to continue.     Confirm that the settings are correct. If any error occurs, press "back" to return for the check. Press execute to make the settings take effect.     After the configuration is complete, press "finish" to end MySQL installation and configuration. A common error is that MySQL cannot be started. Service, usually appeared on the server where MySQL was previously installed. To solve this problem, first ensure that the previously installed MySQL server is completely If not, check whether the previous password has been modified according to the previous steps. If not, Back up the data folder in the MySQL installation directory and delete it. After installation is complete, delete the generated data folder. And then restart the MySQL service. In this case, you may need to check the database and then repair it. Repeat once to prevent data errors.   Iii.
