MySql_5.5安装现用图解说明书(超详细)
完美解决mysql5.5无法插入中文数据及插入后显示乱码(亲测成功)
将对应的last1都改为utf8；并在 client 和mysqid的port下都添加一句
default-character-set=utf8
3.在数据库中
show Variables like'%set%';
敲如下命令；SET character_set_database=utf8;
在试试下面这句：
SET character_set_results=gbk;
现在你查询出来的可能就不是乱码了！
但是通常需要每次都得执行上面的语句才能将乱码变为正常！虽然有点麻烦，但起码也比插入不了数据库强是吧，并且这种方法，在用eclipse JDBC连接数据库的时候，是不会出现乱码的！
SET character_set_server=utf8;
SET character_set_client=gbk;
SET racter_set_connection=gbk;
之后完所有命令，现在就应该可以插入中文了，
但是先别高兴再早奥！！如果我没猜错的话，现在的确可以插入中文了，但是从数据库里读出的中文数据一定是乱码吧？？？怎么办？？
1.安装数据5.5 D:\Program Files\安装包\mysql-5.5.20-win32.msi
根据提示点击下一步，需要特别注意，在选择编码格式的时候一定要 选utf8，切忌不可使用系统自带lasten1，否则后面会很麻烦。
2.打开安装目录C:\Program Files\MySQL\MySQL Server 5.5\my.ini

You can use the pwdmgr.bat command toobtain passwords in clear text or update the latest passwords to the file.Usually, a user can use the database management tool to change the database password of a certainiMC module. To ensure communication between iMC and the database, use the pwdmgr.bat commandto update the corresponding password in file server-addr.xml. If iMC is deployed in distributed mode,you must update the password for every iMC server, as shown in Figure 35.Figure 35Update database passwords for iMCIn the preceding commands, dbpasswd represents the latest database password of the user imc_config,config_db represents the database name, and 192.168.20.107 represents the IP address of the database.To obtain the IP address and name of a MySQL database, view the settings of the corresponding user infile $IMCROOT/common/conf/server-addr.xml.21。

mysql5.5安装配置方法图文教程
mysql5.5安装配置⽅法图⽂教程回忆⼀下mysql 5.5 安装配置⽅法，整理mysql 5.5 安装配置教程笔记，分享给⼤家。
1、⾸先进⼊的是安装引导界⾯2、然后进⼊的是类型选择界⾯，这⾥有3个类型：Typical（典型）、Complete（完全）、Custom（⾃定义）。
这⾥建议选择“⾃定义”（Custom）安装，这样可以⾃定义选择MySQL的安装⽬录，然后点“Next”下⼀步，出现⾃定义安装界⾯，为了数据安全起见，不建议将MySQL安装系统盘C⽬录。
3、准备安装4、安装完成之后会出现MySQL配置的引导界⾯5、这⾥有个引导配置MySQL的选项（Luanch the MySQL Instance Configuration Wizard），建议勾选⽴即配置你的MySQL6、这⾥是配置MySQL的 MySQL配置的类型，可以选择两种配置类型：Detailed Configuration（详细配置）和Standard Configuration（标准配置）。
Standard Configuration（标准配置）选项适合想要快速启动MySQL⽽不必考虑服务器配置的新⽤户。
详细配置选项适合想要更加细粒度控制服务器配置的⾼级⽤户。
如果你是MySQL的新⼿，需要配置为单⽤户开发机的服务器，Standard Configuration（标准配置）应当适合你的需求。
选择Standard Configuration（标准配置）选项，则 MySQL Configuration Wizard（配置向导）⾃动设置所有配置选项，但不包括服务选项和安全选项。
Standard Configuration（标准配置）设置选项可能与安装MySQL的系统不兼容。
如果系统上已经安装了MySQL和你想要配置的安装，建议选择详细配置。
这⾥本⼈选择的是Detailed Configuration ，想更好的完成个性化定制。
7、这⾥是配置MySQL的 MySQL服务器类型，可以选择3种服务器类型，选择哪种服务器将影响到MySQL Configuration Wizard（配置向导）对内存、硬盘和过程或使⽤的决策。
mysql5.5安装步骤
MySQL数据库的安装一共分为两个部分：数据库的安装和数据库的配置。
一MySQL数据库的安装：1、双击下载的MySQL安装文件，如图所示：2、弹出MySQL5.5安装向导对话框，单击Next按钮，如图所示：3、打开End-User License Agreement对话框，选中I accept the terms in the License Agreement复选框，单击Next按钮，如图所示：4、打开Choose Setup Type对话框，在其中列出了3中安装类型，分别是Typical、Custom 和Complete。
如果选择Typical或Complete这两种安装方式，将进入确认对话框，确认选择并开始安装。
如果选择Custom，将进入Custom(自定义)对话框。
在这里选择Custom，单击Custom按钮，如图所示：其中3种安装类型的含义如下：Typical:安装MySQL服务器，MySQL命令行客户端和命令行使用程序，命令行客户端和实用程序包括mysqldump、myisamchk和其他几个工具来帮助管理MySQL服务器。
Complete:安装软件包内包含的所有组件。
完全安装软件包包括的组件有嵌入式服务器库、基准套件、支持脚本和文档。
Custom:安装允许完全控制想要安装的软件包和安装路径。
5、打开Custom Setup对话框，所有可用组件列入Custom Setup对话框左侧的树状视图内，未安装的组件用红色图标表示，已经安装的组件有灰色图标，如图所示：6、默认情况下，选择全部安装，要想更改组件，单击该组件的图标并从下拉列表中选择新的选项，并设置安装路径，单击Next按钮，如图所示：其中四个选项的意思分别是：Will be installed on local had drive:表示安装这个附加组件到本地硬盘。
Entire feature will be installed on local hard driver:表示将这个组件特性及其子组件到本地硬盘。
linux mysql5
linux mysql5.5 安装教程Linux MySQL 5.5安装教程MySQL是一款常用的关系型数据库管理系统，它的安装对于Linux系统来说非常重要。
本教程将指导您在Linux系统上安装MySQL 5.5，下面是具体的步骤：第一步：更新系统在安装任何软件之前，我们首先要确保系统是最新的。
使用以下命令更新系统软件包：sudo apt-get update这将获取并安装最新的软件包信息。
第二步：安装MySQL服务器接下来，我们将安装MySQL服务器。
使用以下命令执行安装：sudo apt-get install mysql-server-5.5这将安装MySQL 5.5版本的服务器。
在安装过程中，系统会要求您创建root用户的密码，请确保您设置一个强密码并记住它，因为这是您日后访问MySQL服务器的凭证。
第三步：检查MySQL服务器的状态安装完成后，我们可以使用下面的命令检查MySQL服务的状态：sudo service mysql status该命令将显示MySQL服务器是否正在运行。
第四步：登录MySQL安装完成后，我们可以使用以下命令登录到MySQL服务器：mysql -u root -p命令将提示您输入root用户的密码，输入密码后按下回车键即可登录到MySQL服务器。
第五步：测试MySQL接下来，我们可以使用以下命令测试MySQL服务器是否正常工作：SHOW DATABASES;该命令将显示MySQL服务器中的所有数据库。
第六步：配置MySQL如果您需要更改MySQL的一些基本设置，如端口号或数据目录等，您可以编辑MySQL的配置文件。
配置文件的位置可能因操作系统的不同而有所不同。
使用以下命令打开MySQL配置文件：sudo nano /etc/mysql/f您可以在此文件中更改各种MySQL服务器的设置。
第七步：常用MySQL命令以下是一些常用的MySQL命令：- 创建新的数据库：CREATE DATABASE database_name;- 显示数据库列表：SHOW DATABASES;- 选择数据库：USE database_name;- 显示表格列表：SHOW TABLES;- 显示表格结构：DESCRIBE table_name;- 导入SQL文件：source /path/to/sql/file.sql;这些命令将帮助您在MySQL服务器上进行常见的数据库操作。
