织梦用解压文件里写着有mysql4/5，请问能用mysql6吗？

Question

如题所述

Answer 1

安装MySQLmysql-5.6.14可以参考如下安装步骤：

1、将解压缩后的文件放到自己想要的地方，并配置环境变量。示例中存放的目录为：F:\mysql\mysql-5.6.14-winx64

2、在环境变量中添加：MYSQL_HOME:F:\mysql\mysql-5.6.14-winx64，在path路径中加入：%MYSQL_HOME%\bin。配置环境变量不是必须的，只是为了能更方便的在命令行中使用mysql的命令行工具。

3、修改ini配置文件

5.6.14的解压缩版里有一个my-default.ini文件，copy一份改名为my.ini放在同级目录下。修改my.ini， my.ini内容如下：

# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html
# *** DO NOT EDIT THIS FILE. It's a template which will be copied to the
# *** default location during install, and will be replaced if you
# *** upgrade to a newer version of MySQL.
[mysqld]
loose-default-character-set=utf8
basedir = F:/mysql/mysql-5.6.14-winx64
datadir = F:/mysql/mysql-5.6.14-winx64/data
[client]
loose-default-character-set=utf8
[WinMySQLadmin]
Server=F:/mysql/mysql-5.6.14-winx64/bin/mysqld.exe
# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M
# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin
# 设置mysql的安装目录
# 设置mysql数据库的数据存放目录
# These are commonly set, remove the # and set as required.
# basedir = .....
# datadir = .....
# port = .....
# server_id = .....
character-set-server=utf8
# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

4、安装服务

开始——所有程序——附件——命令提示符，右键以管理员身份运行。 输入命令：
C:\>f:
F:\>cd F:\mysql\mysql-5.6.14-winx64\bin
F:\mysql\mysql-5.6.14-winx64\bin>mysqld -install
Service successfully installed.

5、启动服务
F:\mysql\mysql-5.6.14-winx64\bin>cd\
F:\>net start mysql
MySQL 服务正在启动 .
MySQL 服务已经启动成功。

6、配置用户
还在上面的命令窗口里面，输入命令：mysql -u root -p
回车后提示输入密码。
mysql解压缩版初次安装管理员root的密码为空，因此直接再回车一次就登入mysql数据库了。

F:\>mysql -u root -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 1

成功后
输入命令：use mysql;　　　　　　/*使用mysql数据库*/
mysql> use mysql
Database changed
输入命令：select host,user,password from user;　　　　/* 查看系统的账户信息 */
mysql> select host,user,password from user;
+-----------+------+----------+
| host | user | password |
+-----------+------+----------+
| localhost | root | |
| 127.0.0.1 | root | |
| ::1 | root | |
| localhost | | |
+-----------+------+----------+
4 rows in set (0.00 sec)
host：代表mysql服务允许哪个IP来的请求。localhost和127.0.0.1指mysql服务所在的主机，即本地。：：1是IPV6的IP地址写法，
全称为：0000:0000:0000:0000:0000:0000:0000:0001。现在都是IPV4的网络，可以不用管他。
user：指账户名称。不同的host下账户名称可以相同。
password：密码。
可以看到，默认账户里只支持本地连接，并且账户没有密码。现在的问题明确了，就是要将匿名用户删除，为root用户添加远程访问和密码，再为自己添加个人账户。指令如下：

mysql> update user set password=PASSWORD('root') where user='root';
Query OK, 3 rows affected (0.00 sec)
Rows matched: 3 Changed: 3 Warnings: 0

| ::1 | root | *81F5E21E35407D884A6CD4A731AEBFB6AF209E1B |
| localhost | | |
+-----------+------+-------------------------------------------+
4 rows in set (0.00 sec)
mysql> commit;
Query OK, 0 rows affected (0.00 sec)
mysql> flush privileges;
