本篇内容介绍了"Windows Server 2008怎么安装MySQL Community Server 5.7.16"的有关知识,在实际案例的操作过程中,不少人都会遇到这样的困境,接下来就让小编带领大家学习一下如何处理这些情况吧!希望大家仔细阅读,能够学有所成!
0.下载安装介质
我们可以登录MySQL官网来下载安装介质,网址是:http://dev.mysql.com/downloads/。我选择的是64位压缩包版本"Windows (x86, 64-bit), ZIP Archive"。
1.解压缩
将下载到本地的安装介质解压缩。然后,将解压后的文件夹mysql-5.7.16-winx64拷贝到安装目录(E盘根目录)下。
2.设置系统环境变量
右键点击 计算机>>属性>> 高级系统属性>>环境变量>> 编辑 Path ,在最后添加" ;E:\mysql-5.7.16-winx64\bin",确定。
3.创建my.ini 文件和data目录,配置安装路径与数据存储路径
在E:\mysql-5.7.16-winx64目录下创建data目录和my.ini,并在my.ini中配置安装路径与数据存储路径等信息。
点击(此处)折叠或打开
[mysql]
default-character-set=utf8
[mysqld]
max_connections=200
default-storage-engine=INNODB
basedir =E:\mysql-5.7.16-winx64\bin
datadir =E:\mysql-5.7.16-winx64\data
port = 3306
4.安装MySQL服务
首先,以管理员身份运行 cmd 并切换到MySQL的bin目录下;
接下来,执行mysqld --initialize-insecure
这条命令用来初始化data文件,其中insecure选项指定登录无需口令。
点击(此处)折叠或打开
D:\>e:
E:\>cd mysql-5.7.16-winx64
E:\mysql-5.7.16-winx64>cd bin
E:\mysql-5.7.16-winx64\bin>mysqld --initialize-insecure
E:\mysql-5.7.16-winx64\bin>
需要注意的是,如果不指定insecure选项,则会随机生成登陆密码, 在E:\mysql-5.7.16-winx64\data文件夹下,有一个 hoegh.err 文件,其中hoegh是主机名,打开会看到:
2016-10-20T09:34:56.806257Z 1 [Note] A temporary password is generated for root@localhost: p-mcI:ijR6Xg,
其中 p-mcI:ijR6Xg即为随机密码。
然后,输入 mysqld --install安装MySQL服务
我们会看到界面出现:Server successfully installed,这就说明MySQL服务安装成功。
点击(此处)折叠或打开
E:\mysql-5.7.16-winx64\bin>
E:\mysql-5.7.16-winx64\bin>mysqld --install
Service successfully installed.
E:\mysql-5.7.16-winx64\bin>
5.启动MySQL服务
输入 net start mysql 回车, 就会看到: MySQL 服务已经启动成功。尝试使用root用户登录数据库,并通过show databases命令查看数据库概要信息。
点击(此处)折叠或打开
E:\mysql-5.7.16-winx64\bin>
E:\mysql-5.7.16-winx64\bin>net start mysql
MySQL 服务正在启动 .
MySQL 服务已经启动成功。
E:\mysql-5.7.16-winx64\bin>mysql -u root
