1.首先在mysql官网下载最新版mysql, 附上链接点击打开链接,根据你的系统型号选择对应的包下载,大约300多兆,版本号为5.7.19
下载完之后,解压缩,是一个标准的mysql文件
2.第二步,配置系统环境变量,桌面→我的电脑→右键"属性"→高级系统设置→环境变量→系统变量→新建
变量名可以根据喜好随便取,我这里叫做MYSQL_HOME,变量值是你刚刚下载的mysql文件夹所在的目录,我们指向其中的bin目录,然后一路确定返回
3.我们的mysql文件中没有默认的配置文件,我们新建一个.ini的配置文件,名字为my-default.ini,里边内容如下:
# 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]
# 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:\mysql-server
# datadir = D:\mysql-server\data
# port = .....
# server_id = .....
#设置服务器字符集为utf8
character_set_server=utf8
collation-server=utf8_general_ci
#设置mysql的安装目录
basedir = D:\mysql-server
#设置mysql的数据文件存放目录
datadir = D:\mysql-server\data
#设置mysql服务所绑定的端口
port = 3306
#设置mysql允许的最大连接数
max_connections=15
# 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
[client]
#设置客户端字符集
default-character-set=utf8
[WinMySQLadmin]
Server = D:\mysql-server\bin\mysqld.exe
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
注意里面的几个路径,一定要修改为你的mysql文件夹所在的路径,由于我放的目录是D:\mysql-server,所以上面的配置路径都为这个
***!!注意:上面有个data文件夹是需要自己建立在mysql文件夹里的。不建立的话下面的cmd命令会报错。
4.准备安装mysql,通过命令行工具安装
首先以管理员身份启动cmd !!!注意!!!,一定要以管理员身份启动,否则后面会报错,提示权限不够
命令如下: mysqld -install 如果出现以下提示,说明安装成功
然后开始启动服务,命令: net start mysql
(没建立data文件夹,出现错误的解决方法)
报错了,提示无法启动,3534 ,我们通过 mysqld --console命令来查看错误日志
这里提示,mysql文件夹下没有\data这个文件或者路径,这时我们新建一个
我们用命令进入到mysql文件夹的路径,输入以下命令:
mysqld --initialize-insecure --user=mysql
执行完上面命令后,MySQL会自建一个data文件夹,并且建好默认数据库,登录的用户名为root,密码为空
这时我们再重新启动mysql,发现就能正常启动了
