看着官网文档搞了半天,也不知所已,最后还是搜索了一下,还是中文好懂
1 下载解压部分略。。。
2 添加环境变量
在path后加上xx盘:/xx目录/mysql-5.7.12-winx64/bin
3 mysql-5.7.12-winx64目录下新建my.ini配置文件(也可以直接复制my-default文件然后改名),打开my.ini文件,里面写入以下内容(具体路径,以自己的为准)
# 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 ="D:/软件/web/mysql/mysql-5.7.12-winx64/" datadir ="D:/软件/web/mysql/mysql-5.7.12-winx64/data/" tmpdir ="D:/软件/web/mysql/mysql-5.7.12-winx64/data/" socket ="D:/软件/web/mysql/mysql-5.7.12-winx64/data/mysql.sock" log-error="D:/软件/web/mysql/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="D:/软件/web/mysql/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" #sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
4 cmd 以管理员身份进入“命令提示符”
cd 进入mysql-5.7.12-winx64\bin目录下
输入:mysqld --initialize 会自动添加data目录
输入:mysqld install MySQL --defaults-file="D:/xx目录/mysql-5.7.12-winx64/my.ini" 具体路径根据自己的去写(如果提示已经有了 就输入mysqld remove 移除再执行上面的命令)
输入:net start mysql 就可以启动啦
mysql的默认密码为空哦, 你可以自己去设置mysql的密码
补充一下改密码的命令:
进入mydql>后
输入 mysql>use mysql
mysql> update user set authentication_string=password(‘123456‘)where user=‘root‘;
mysql> flush privileges;
mysql> quit
