# 4、配置MYSQL #

在E:\\software\\mysql-8.0.14-winx64新建一个.ini格式文件my.ini。其中my.ini内容为

[mysqld]
    port=3306
    # 设置mysql的安装目录
    basedir=E:/software/mysql-8.0.14-winx64    -- 根据需要更改,并且路径不能是\,否则会出现找不到路径的错误
    # 设置mysql数据库的数据的存放目录
    datadir=E:/software/mysql-8.0.14-winx64/data  -- 根据需要更改,并且路径不能是\,否则会出现找不到路径的错误
    # 允许最大连接数
    max_connections=200
    # 允许连接失败的次数。这是为了防止有人从该主机试图攻击数据库系统
    max_connect_errors=10
    # 服务端使用的字符集默认为utf8mb4
    character-set-server=utf8mb4
    # 创建新表时将使用的默认存储引擎
    default-storage-engine=INNODB
    
    ########log settings######## 
    expire_logs_days = 30 
    log_error = error.log 
    slow_query_log = 1 
    slow_query_log_file = slow.log 
    long_query_time = 2 
    log_timestamps = SYSTEM 
    log_slow_admin_statements = 1  
    log_slow_slave_statements = 1 
    min_examined_row_limit = 1000
    
    [mysql]
    # 设置mysql客户端默认字符集
    default-character-set=utf8mb4

# 5、安装并启动MYSQL服务器 #

以管理员身份打开cmd命令提示行，并进入安装目录的bin目录下：cd /d E:\\software\\mysql-8.0.14-winx64\\bin  
![在这里插入图片描述][20190123093810141.png]

*  初始化：mysqld --initialize-insecure并且以执行安装命令mysqld -install【如果已经安装了mysqld，先删除：mysqld -remove MySQL】  
    ![在这里插入图片描述][20190123100922225.png]  
    执行mysqld --initialize-insecure之后E:\\software\\mysql-8.0.14-winx64自动传教了data目录  
    mysqld --initialize-insecure的目录是免密登陆初始化  
    ![在这里插入图片描述][20190123101150478.png]  
    备注：如果不以管理员身份打开cmd命令行，会出现错误：  
    ![在这里插入图片描述][20190123093906516.png]
 *  启动服务器net start mysql

修改密码为123456：ALTER USER root@localhost IDENTIFIED BY ‘123456’;
