之前安装mysql时未做总结,换新电脑,补上安装记录,安装的时候,找了些网友的安装记录,发现好多坑

1、mysql-5.7.12-winx64.zip下载
官方下载地址:http://dev.mysql.com/downloads/mysql/

2.解压到C:\job\mysql-5.7.12-winx64 

3.在C:\job\mysql-5.7.12-winx64下新建my.ini配置文件
内容如下:

####################配置文件开始###################

 # For advice on how to change settings please see

 # http://dev.mysql.com/doc/refman/5.7/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.

 [client]

 default-character-set=utf8

 

 [mysqld]

 port=3306

 basedir ="C:\job\mysql-5.7.12-winx64/"

 datadir ="C:\job\mysql-5.7.12-winx64/data/"

 tmpdir ="C:\job\mysql-5.7.12-winx64/data/"

 socket ="C:\job\mysql-5.7.12-winx64/data/mysql.sock"

 log-error="C:\job\mysql-5.7.12-winx64/data/mysql_error.log"

 

 #server_id = 2

 #skip-locking

 

 max_connections=100

 table_open_cache=256

 query_cache_size=1M

 

 tmp_table_size=32M

 thread_cache_size=8

 

 innodb_data_home_dir="C:\job\mysql-5.7.12-winx64/data/"

 innodb_flush_log_at_trx_commit =1

 innodb_log_buffer_size=128M

 innodb_buffer_pool_size=128M

 innodb_log_file_size=10M

 innodb_thread_concurrency=16

 innodb-autoextend-increment=1000

 join_buffer_size = 128M

 sort_buffer_size = 32M

 read_rnd_buffer_size = 32M

 max_allowed_packet = 32M

 explicit_defaults_for_timestamp=true

 sql-mode="STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"

 skip-grant-tables

 #sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

####################配置文件结束###################

重点是以下配置,其中datadir的目录名称必须是:C:\job\mysql-5.7.12-winx64/data/,加上skip-grant-tables,使root不输密码,登陆

4.在windows系统环境变量path,加入如下内容
C:\job\mysql-5.7.12-winx64\bin;(注意加分号) 

5、将mysql注册为windows系统服务
具体操作是在命令行中执行以下命令(需要以管理员身份运行命令行):

cd C:\Windows\System32
以管理员身份运行cmd.exe
需要切换到bin目录,否则,会将服务目录指定为C:\job\mysql-5.7.12-winx64\bin

增加服务命令:mysqld install MySQL --defaults-file="C:\job\mysql-5.7.12-winx64\my.ini"

移除服务命令为:mysqld remove

6.第5步成功后,初始化data目录
C:\job\mysql-5.7.12-winx64\bin>mysqld  --initialize
此步骤非常重要,未初始化,可能会导致mysql服务无法启动(坑一)

7.打开系统服务管理
可以看到mysql系统服务

在命令行启动mysql命令为: net start mysql

     关闭mysql命令为:net stop mysql

8、修改root密码
命令行执行:

mysql –uroot

mysql>show databases;

mysql>use mysql;
mysql> update mysql.user set authentication_string=password('12345') where user='root' and Host = 'localhost';

mysql> alter user 'root'@'localhost' identified by '12345';

mysql> FLUSH PRIVILEGES;

mysql> QUIT

坑二:新版的mysql数据库下的user表中已经没有Password字段了,而是将加密后的用户密码存储于authentication_string字段

9、远程登陆配置
允许root用户在任何地方进行远程登录,并具有所有库任何操作权限,具体操作如下:

1)在本机先使用root用户登录mysql:

命令行执行:mysql -u root -p

输入密码(第7步中设置的密码):12345

2)进行授权操作:

mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '12345' WITH GRANT OPTION;

重载授权表:

mysql>FLUSH PRIVILEGES;

退出mysql:quit

以上就是mysql 5.7.12winx64安装配置方法,希望对大家的学习有所帮助。
