本文出现的问题有:

1, root(localhost) 用户被删除; 

2, 在关闭mysql服务过后, 无法启动,出现1067错误;


我使用的mysql版本为5.6;

mysql的安装路径: C:\Program Files (x86)\MySQL;

mysql数据路径: C:\ProgramData\MySQL;

my.ini就在数据路径当中;


无法启动mysql服务,出现1067,的解决办法:

删除数据目录下,data目录下的ib_logfile0和ib_logfile1文件。


root用户被删除的解决办法:


1, 关闭mysql服务;

2, 开启mysql56服务;

3, 在my.ini中的[mysql]后面加入: skip-grant-tables

4, 使用命令行登陆mysql: mysql -uroot -p, 无须密码登陆成功;

5, mysql> use mysql;

Database changed

6, mysql> select * from user;

Empty set (0.00 sec) 

7, mysql> insert into user set user='root',ssl_cipher='',x509_issuer='',x509_subject='';

Query OK, 1 row affected (0.00 sec)

(这时可能会提示某字段如ssl_cipher无默认值, 只要加上,ssl_cipher=''; 其字段如有提示依次添加就OK了)


8, mysql> update user set Host='localhost',select_priv='y', insert_priv='y',update_priv='y',delete_priv='y',create_priv='y',drop_priv='y',reload_priv='y',shutdown_priv='y',Process_priv='y',file_priv='y',grant_priv='y',References_priv='y',index_priv='y',create_user_priv='y',show_db_priv='y',super_priv='y',create_tmp_table_priv='y',Lock_tables_priv='y',execute_priv='y',repl_slave_priv='y',repl_client_priv='y',create_view_priv='y',show_view_priv='y',create_routine_priv='y',alter_routine_priv='y',create_user_priv='y' where user='root';

Query OK, 1 row affected (0.00 sec)



9, 去关闭mysql56服务; (如果没有关闭mysql56,就直接去开启mysql就会出现1067错误)

10, 开启mysql服务;

11, 删除my.ini中的之前的那句话;


正常情况下登陆mysql;

原来的数据全部回来了!!!!!

(此时尚未设置root的密码)


注:

在root没有密码的情况下 输入密码登陆就会失败;

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.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
