**前提：mysql是zip版本的**

下载地址https://dev.mysql.com/downloads/mysql/

步骤

1.添加环境变量MYSQL\_HOME等于mysql的安装路径

我的是C:\\Program Files\\MYSQL55\\mysql-5.5.60-winx64

![70][]

2.在path环境变量中添加mysql安装路径下面的bin目录

即：%MYSQL\_HOME%\\bin

3.在安装目录下面建一个文件my.ini，并将以下代码的添加进去

# Example MySQL config file for small systems.
    #
    # This is for a system with little memory (<= 64M) where MySQL is only used
    # from time to time and it's important that the mysqld daemon
    # doesn't use much resources.
    #
    # MySQL programs look for option files in a set of
    # locations which depend on the deployment platform.
    # You can copy this option file to one of those
    # locations. For information about these locations, see:
    # http://dev.mysql.com/doc/mysql/en/option-files.html
    #
    # In this file, you can use all long options that a program supports.
    # If you want to know which options a program supports, run the program
    # with the "--help" option.
    
    # The following options will be passed to all MySQL clients
    [client]
    #password	= your_password
    port		= 3306
    socket		= /tmp/mysql.sock
    loose-default-character-set = utf8 
    
    # Here follows entries for some specific programs
    
    # The MySQL server
    
    [WinMySQLadmin] 
    Server = C:/Program Files/MYSQL55/mysql-5.5.60-winx64/bin/mysqld.exe 
    
    [mysqld]
    port		= 3306
    socket		= /tmp/mysql.sock

    key_buffer_size = 16K
    max_allowed_packet = 1M
    table_open_cache = 4
    sort_buffer_size = 64K
    read_buffer_size = 256K
    read_rnd_buffer_size = 256K
    net_buffer_length = 2K
    thread_stack = 128K
    
    
    loose-default-character-set = utf8 
    character-set-server = utf8
    basedir = C:/Program Files/MYSQL55/mysql-5.5.60-winx64 datadir = C:/Program Files/MYSQL55/mysql-5.5.60-winx64/data 
    
    
    # Don't listen on a TCP/IP port at all. This can be a security enhancement,
    # if all processes that need to connect to mysqld run on the same host.
    # All interaction with mysqld must be made via Unix sockets or named pipes.
    # Note that using this option without enabling named pipes on Windows
    # (using the "enable-named-pipe" option) will render mysqld useless!
    # 
    #skip-networking
    server-id	= 1
    
    # Uncomment the following if you want to log updates
    #log-bin=mysql-bin
    
    # binary logging format - mixed recommended
    #binlog_format=mixed
    
    # Causes updates to non-transactional engines using statement format to be
    # written directly to binary log. Before using this option make sure that
    # there are no dependencies between transactional and non-transactional
    # tables such as in the statement INSERT INTO t_myisam SELECT * FROM
    # t_innodb; otherwise, slaves may diverge from the master.
    #binlog_direct_non_transactional_updates=TRUE
    
    # Uncomment the following if you are using InnoDB tables
    #innodb_data_home_dir = C:\\mysql\\data\\
    #innodb_data_file_path = ibdata1:10M:autoextend
    #innodb_log_group_home_dir = C:\\mysql\\data\\
    # You can set .._buffer_pool_size up to 50 - 80 %
    # of RAM but beware of setting memory usage too high
    #innodb_buffer_pool_size = 16M
    #innodb_additional_mem_pool_size = 2M
    # Set .._log_file_size to 25 % of buffer pool size
    #innodb_log_file_size = 5M
    #innodb_log_buffer_size = 8M
    #innodb_flush_log_at_trx_commit = 1
    #innodb_lock_wait_timeout = 50
    
    [mysqldump]
    quick
    max_allowed_packet = 16M
    
    [mysql]
    no-auto-rehash
    # Remove the next comment character if you are not familiar with SQL
    #safe-updates
    
    [myisamchk]
    key_buffer_size = 8M
    sort_buffer_size = 8M
    
    [mysqlhotcopy]
    interactive-timeout

**   注意上面的有几个地方需要改一下，那就将路径改为你的mysql安装路径就可以了，一共三个地方，已经加粗了**

** ****4.打开命令提示符，进入%MYSQL\_HOME%/bin目录，执行命令：mysqld -install将mysql安装到windows的服务。执行成功后会提示：C:\\Program Files\\MYSQL55\\mysql-5.5.60-winx64\\bin>Service successfully installed. **

**  ![70 1][]**

**5.打开mysql服务**

**   net start mysql   打开服务**

**   net syop mysql  停止mysql服务**

**![70 2][]**

**6，执行mysql -u root**

**    这时我们不需要输入密码就可以进入到mysql，因为是第一次登陆是不需要密码的**

**7.进入到这里面之后，修改密码即可**

**  mysql> update mysql.user set password=PASSWORD('123456') where User='root'  
mysql> flush privileges**
