Mac mysql sql_model引起的问题

问题：

我这里时应为timestamp引起的，服务器的数据使用的mysql5。本地使用的是mysql8，sql_model 不同导致数据不能够在数据库中添加。

解决：

在/etc/下查找my.cnf文件，如果有就使用，没有新建一个my.cnf文件，

然后开始编辑，sudo vi /etc/my.cnf

具体内容如下，网上找的。然后就是问题关键所在了。sql_model的配置

需要在

  [mysqld]

　　sql_mode=''

我这里图省事，就写了空。可以找几个网站，去查看每个选项的作用

# Example MySQL config file for medium systems.
  #
  # This is for a system with little memory (32M - 64M) where MySQL plays
  # an important part, or systems up to 128M where MySQL is used together with
  # other programs (such as a web server)
  #
  # 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]
  default-character-set=utf8
  #password   = your_password

# 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
# (via the "enable-named-pipe" option) will render mysqld useless!

  # Replication Master Server (default)
  # binary logging is required for replication
  log-bin=mysql-bin  

    # binary logging format - mixed recommended
    binlog_format=mixed  

      # required unique id between  and ^ -

    # Replication Slave (comment out master section to use this)
    #
    # To configure this host as a replication slave, you can choose between
    # two methods :
    #
    # ) 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=,
    #    MASTER_USER='joe', MASTER_PASSWORD='secret';
    #
    # OR
    #
    # ) 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  and ^ -
    # (and different from the master)
    # defaults to  if master-host is set
    # but will not function as a slave if omitted
    #server-id       =
    #
    # 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
    #master-port     =  <port>
    #
    # binary logging - not required for slaves, but recommended

下一步可能需要权限

sudo chmod 664　/etc/my。cnf
