本文记录了mysql 5.7.21安装配置方法,具体内容如下 1.下载 解压到自己喜欢的一个位置即可(目录中不要包含中文) 如:D:\Program Files\ 2.系统环境变量配置 (1)新增系统变量 变量名:MYSQL_HOME (2)追加PATH ;%MYSQL_HOME%\bin; 3.配置my.ini文件 在解压根目录新建一个my.ini的文件 # 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:\\Program Files\mysql-5.7.21-winx64" datadir = "D:\\Program Files\mysql-5.7.21-winx64\data" port = 3306 character_set_server = utf8 # 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 4.管理员方式启动命令提示窗符 进入mysql解压目录到bin目录下 如:D:\Program Files\mysql-5.7.21-winx64\bin 分别执行: (1)初始化:mysqld -initialize-insecure 如果报错failed to set datadir to 则 执行一下 mysqld --initialize --user=mysql --console,再执行(1); 正确之后会在Mysql解压根目录生成data文件夹以及相关文件 (2)mysqld -install *如提示Install/Remove of the Service Denied,说明不是已管理员的方式进入的命令提示符 (3)启动服务:net start mysql (4)登陆,改密码 mysql -u root -p 【成功登陆的直接到(5)】 我的出现了 在my.ini中增加 重启服务,成功登陆 (5)执行改密码语句 (正常登陆的使用set password= password(‘新密码'); ) update user set authentication_string = password("新密码") where user='root'; (6)exit; net stop mysql (7)登陆成功的忽略这一步 到my.ini中注释掉 重启进入之后set password= password(‘新密码'); 到此就可以正常使用了。 (8)测试 show databases; 5.写两个bat文件用于启动和关闭mysql服务 (1)启动mysql服务 @echo off echo 确定要启动MySQL服务吗? pause net start mysql echo 启动MySQL服务完成,请确认有没有错误发生。 Pause 保存为 mysql服务启动.bat 文件,运行时要以管理员方式运行 (2)关闭mysql服务 @echo off echo 确定要关闭MySQL服务吗? pause net stop mysql echo 关闭MySQL服务完成,请确认有没有错误发生。 Pause 保存为 mysql服务关闭.bat 文件,运行时要以管理员方式运行 MySql到此安装结束。 精彩专题分享: 以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持极客世界。 |
