mysql下载解压后，安装报错

Question

Answer 1

1.下载MySQL

访问https://dev.mysql.com/downloads/mysql/5.6.html#downloads，下载操作系统对应的版本（无账号需先注册一个），以mysql-5.6.38-win32为例

2.解压

以解压到D:\soft_dev\mysql-5.6.38-win32为例

3.修改配置文件

解压完mysql-5.6.38-win32目录下有一个配置文件模板my-default.ini，复制一份并命名为my.ini，修改内容如下：

复制代码

*** 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]

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

These are commonly set, remove the # and set as required.

basedir = D:/soft_dev/mysql-5.6.38-win32
datadir = D:/soft_dev/mysql-5.6.38-win32/data

port = .....

server_id = .....

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
复制代码
注意：

　　（1）配置文件起作用的两种方式：创建my.ini、启动服务时指定defaults-file

　　（2）basedir、datadir路径中要用/分隔符不能用\，负责启动服务会报配置错误导致的1067错误

　　（3）MySQL5.6.8之前会将配置文件直接放到安装目录下，之后的版本在服务启动过程中会按照一定的目录优先级搜素my.ini

4.安装MySQL服务

进入D:\soft_dev\mysql-5.6.38-win32\bin目录，执行mysqld.exe -install安装服务（如果360安全卫士有监测，允许本次操作），mysqld.exe -remove移除服务，效果可在windows服务列表中查看

5.启动服务

任意位置执行net start mysql

此时再查看Windows服务列表MySQL状态为启动，且启动类型为自动

6.远程登陆用户设置

进入D:\soft_dev\mysql-5.6.38-win32\bin目录，执行mysql -uroot，进入mysql，此时为root免密登录

mysql> use mysql;

mysql> select host,user,password from user;

mysql> update user set password=password('123456') where user='root';

mysql> update user set host='%' where user='root' and host='localhost';

mysql> GRANT ALL PRIVILEGES ON . TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;

mysql> flush privileges;

mysql> exit

7.修改字符集及其他配置信息

(1) 查看字符集

(2) 修改字符集，修改后my.ini文件内容为：

复制代码

(3) 重启MySQL服务

再次查看字符集
