由于出差需要,今天在Mac OS X的Win 7虚拟机上安装了MySQL的最新版本:mysql-5.6.20-winx64.msi,结果发现安装完以后没有任何反应,开始菜单里面的CommandLine Shell也无法启动。虽然问题很简单,但估计会有很多朋友遇到类似问题,所以总结一下解决方案:
看网上有人介绍,在MySQL的安装目录下,例如我这里的:C:\Program Files\MySQL\MySQL Server 5.6\bin,其下有mysqld.exe这个可执行文件,可以安装服务。但是我运行了:
mysqld.exe --installcmd中显示:Install/Remove of the Service Denied!,搜索了一下,解决方案也很简单,在C:\Windows\System32 找到cmd.exe,然后点击右键——“以管理员身份运行”,然后再运行刚才的命令,就可以了。5.6.20版本的MySQL似乎默认采用了最简单的安装设置,默认root的密码为空。启动了刚才安装的服务后,就可以正常运行了。

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.
