• 关于mysql-5.7.23-winx64.msi的安装


    1. 访问搜狐镜像 http://mirrors.sohu.com/mysql/MySQL-5.7/ 下载 mysql-5.7.23-winx64.msi 

    2. 安装 mysql-5.7.23-winx64.msi  ,选择custom方式安装,就可以选择安装路径,否则默认安装在C盘,然后一路 next 。

    3. 进入 mysql 安装目录:

        此时你可能会发现两个问题:一是没有my.ini文件,二是没有data文件夹;

        3.1 若没有my.ini文件,则自己创建个my.ini文件,将以下内容Copy进去

        

     1 # For advice on how to change settings please see
     2 # http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html
     3 # *** DO NOT EDIT THIS FILE. It's a template which will be copied to the
     4 # *** default location during install, and will be replaced if you
     5 # *** upgrade to a newer version of MySQL.
     6 [client]
     7 default-character-set = utf8
     8 [mysql]
     9 default-character-set = utf8
    10 [mysqld]
    11 character-set-client-handshake = FALSE
    12 character-set-server = utf8
    13 collation-server = utf8_bin
    14 init_connect='SET NAMES utf8'
    15 # Remove leading # and set to the amount of RAM for the most important data
    16 # cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
    17 innodb_buffer_pool_size = 128M
    18 # Remove leading # to turn on a very important data integrity option: logging
    19 # changes to the binary log between backups.
    20 # log_bin
    21 # These are commonly set, remove the # and set as required.
    22 basedir = D:mysql
    23 datadir = D:mysqldata
    24 port = 3306
    25 # server_id = .....
    26 # Remove leading # to set options mainly useful for reporting servers.
    27 # The server defaults are faster for transactions and fast SELECTs.
    28 # Adjust sizes as needed, experiment to find the optimal values.
    29 join_buffer_size = 128M
    30 sort_buffer_size = 16M
    31 read_rnd_buffer_size = 16M 
    32 sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

       注意,my.ini文件中的路径,要修改为你的安装路径:

       

       3.2 不要新建 data  文件夹(千万不要自己手动建data文件夹,否则服务启动不起来

    4.以管理员身份运行cmd

    5.进入 bin 下

    6. 执行: mysqld  --initialize-insecure --user=mysql   

       接着执行:mysqld --install mysql  --defaults-file=d:mysqlmy.ini 

        ( 此时  mysql为你的服务名,你也可以修改为你定义的名称  已经注册成 windows的系统服务 )

       接着执行:net  start mysql

       ( 或进入 "服务"手动开启 )

        执行此句后,你可能会遇到服务启动不起来的情况,此时参考如下操作:

    7. 初始密码在:你手动创建的data文件夹中,err文件内:

     

     

     8.若密码为空,则输入:mysql -u root -p ,此时不输入密码,不输入密码,直接回车。便可进入mysql。

        若密码不为空,则执行 mysql -uroot -p 输入初始密码(上一步中控制台已经打印出来了  ,形如: localhost: <Bp(=fF4cAdJ)

    9.重置密码:   alter user 'root'@'localhost' identified by 'root';,这样就将密码设置为了  root;
    10.执行:mysql -u root -p ,回车后,输入密码 root,再次试试登录,如果登录成功,则完成mysql的安装。
