使用MySQLWorkbench远程管理工具进行远程管理Mysql的错误及解决办法_MySQL
概述:
最近要使用MySQL Workbench远程管理工具进行远程管理虚拟机上的MySQL。可是,在配置的过程中,遇到了一些问题,下面是这个问题(HOSt ip is not allowed to connect to this MySql server)的描述以及解决办法。
笔者环境:
本地系统:Window 7
虚拟机系统:CentOS 6.5
MySQL版本:mysql Ver 14.14 Distrib 5.1.73, for redhat-linux-gnu (x86_64) using readline 5.1
MySQL Workbench版本:MySQL Workbench 6.2 CE
错误:
HOSt ip is not allowed to connect to this MySql server
解决过程:
对于这个问题,还是有纠结了一下的。因为我在为两台虚拟机添加远程控制的时候,发现第一台可以过,而第二台怎么都过不了。下面是我的处理过程:
上面的报错信息是因为我们的MySQL没有提供远程控制的服务。我们可以通过以下方法进行解决:
1.改表法:
可能是你的帐号不允许从远程登陆,只能在localhost。
这个时候只要在localhost的那台电脑,登入mysql后,更改 "mysql" 数据库里的 "user" 表里的 "host" 项,从"localhost"改称"%"
mysql> use mysql;
mysql> update user set host = '%' where user = 'root';
mysql> select host, user from user;
2.授权法:
例如,你想myuser使用mypassword从任何主机连接到mysql服务器的话。
mysql> GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'%' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;
如果你想允许用户loginName从ip为192.168.1.6的主机连接到mysql服务器,并使用Password作为密码
mysql> GRANT ALL PRIVILEGES ON *.* TO 'loginName'@'192.168.1.6'IDENTIFIED BY 'Password' WITH GRANT OPTION;
我使用的是上一句。
mysql>FLUSH RIVILEGES;
3.另外一种方法:
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%'WITH GRANT OPTION;
mysql> FLUSH PRIVILEGES;
mysql> EXIT;
关键点:
本人没有进行第3种方法,因为前两种方法可以很好的解决问题。
不过对于改表法,我是没有执行到第三步的。因为第二步就报错了。好吧,那我就来尝试一下授权法。授权法是可以的。就这样我的第一台机器可以使用MySQL Workbench进行远程管理了。
可是当我开始对我的第二台机器进行操作时,很不幸,没能成功。原因是我以为改表法出现了Error就可以直接跳过了,直接进行授权法。可是,这是不行的。于是我改表法又操作了一遍,并且进行了第三步操作,我看到,实际上第二步是修改成功的。
就这样我的两台机器都可以通过MySQL Workbench进行远程管理了。

MySQL functions can be used for data processing and calculation. 1. Basic usage includes string processing, date calculation and mathematical operations. 2. Advanced usage involves combining multiple functions to implement complex operations. 3. Performance optimization requires avoiding the use of functions in the WHERE clause and using GROUPBY and temporary tables.

Efficient methods for batch inserting data in MySQL include: 1. Using INSERTINTO...VALUES syntax, 2. Using LOADDATAINFILE command, 3. Using transaction processing, 4. Adjust batch size, 5. Disable indexing, 6. Using INSERTIGNORE or INSERT...ONDUPLICATEKEYUPDATE, these methods can significantly improve database operation efficiency.

In MySQL, add fields using ALTERTABLEtable_nameADDCOLUMNnew_columnVARCHAR(255)AFTERexisting_column, delete fields using ALTERTABLEtable_nameDROPCOLUMNcolumn_to_drop. When adding fields, you need to specify a location to optimize query performance and data structure; before deleting fields, you need to confirm that the operation is irreversible; modifying table structure using online DDL, backup data, test environment, and low-load time periods is performance optimization and best practice.

Use the EXPLAIN command to analyze the execution plan of MySQL queries. 1. The EXPLAIN command displays the execution plan of the query to help find performance bottlenecks. 2. The execution plan includes fields such as id, select_type, table, type, possible_keys, key, key_len, ref, rows and Extra. 3. According to the execution plan, you can optimize queries by adding indexes, avoiding full table scans, optimizing JOIN operations, and using overlay indexes.

Subqueries can improve the efficiency of MySQL query. 1) Subquery simplifies complex query logic, such as filtering data and calculating aggregated values. 2) MySQL optimizer may convert subqueries to JOIN operations to improve performance. 3) Using EXISTS instead of IN can avoid multiple rows returning errors. 4) Optimization strategies include avoiding related subqueries, using EXISTS, index optimization, and avoiding subquery nesting.

Methods for configuring character sets and collations in MySQL include: 1. Setting the character sets and collations at the server level: SETNAMES'utf8'; SETCHARACTERSETutf8; SETCOLLATION_CONNECTION='utf8_general_ci'; 2. Create a database that uses specific character sets and collations: CREATEDATABASEexample_dbCHARACTERSETutf8COLLATEutf8_general_ci; 3. Specify character sets and collations when creating a table: CREATETABLEexample_table(idINT

To safely and thoroughly uninstall MySQL and clean all residual files, follow the following steps: 1. Stop MySQL service; 2. Uninstall MySQL packages; 3. Clean configuration files and data directories; 4. Verify that the uninstallation is thorough.

Renaming a database in MySQL requires indirect methods. The steps are as follows: 1. Create a new database; 2. Use mysqldump to export the old database; 3. Import the data into the new database; 4. Delete the old database.

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),
