文档里的安装流程：

MySQL :: MySQL 5.7 Reference Manual :: 2.3.5 Installing MySQL on Microsoft Windows Using a noinstall ZIP Archive

1. Extract the main archive to the desired install directory
2. Optional: also extract the debug-test archive if you plan to execute the MySQL benchmark and test suite
3. Create an option file
4. Choose a MySQL server type
5. Initialize MySQL
6. Start the MySQL server
7. Secure the default user accounts

附 wamp 的 my.ini（记得改各个文件夹）：

    ; Example MySQL config file for medium systems.
    ;
    ; This is for a large system with memory of 1G-2G where the system runs mainly
    ; MySQL.
    ;
    ; 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.

    ; Replication Slave (comment out master section to use this)

    ; New for MySQL 5.6 if no slave
    skip-slave-start

    ;
    ; To configure this host as a replication slave, you can choose between
    ; two methods :
    ;
    ; 1) Use the CHANGE MASTER TO command (fully described in our manual) -
    ;    the syntax is:
    ;
    ;    CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
    ;    MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
    ;
    ;    where you replace <host>, <user>, <password> by quoted strings and
    ;    <port> by the master's port number (3306 by default).
    ;
    ;    Example:
    ;
    ;    CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
    ;    MASTER_USER='joe', MASTER_PASSWORD='secret';
    ;
    ; OR
    ;
    ; 2) Set the variables below. However, in case you choose this method, then
    ;    start replication for the first time (even unsuccessfully, for example
    ;    if you mistyped the password in master-password and the slave fails to
    ;    connect), the slave will create a master.info file, and any later
    ;    change in this file to the variables' values below will be ignored and
    ;    overridden by the content of the master.info file, unless you shutdown
    ;    the slave server, delete master.info and restart the slaver server.
    ;    For that reason, you may want to leave the lines below untouched
    ;    (commented) and instead use CHANGE MASTER TO (see above)
    ;
    ; required unique id between 2 and 2^32 - 1
    ; (and different from the master)
    ; defaults to 2 if master-host is set
    ; but will not function as a slave if omitted
    ;server-id       = 2
    ;
    ; The replication master for this slave - required
    ;master-host     =   <hostname>
    ;
    ; The username the slave will use for authentication when connecting
    ; to the master - required
    ;master-user     =   <username>
    ;
    ; The password the slave will authenticate with when connecting to
    ; the master - required
    ;master-password =   <password>
    ;
    ; The port the master is listening on.
    ; optional - defaults to 3306
    ;master-port     =  <port>

    ; binary logging - not required for slaves, but recommended
