解决mac平台的mysql+python的中文乱码问题

首先,针对mysql数据库来说,它的默认字符是:latin1
我们写不进去中文的罪魁祸首就是这个latin1。那么,对应的解决办法就是将这个字符集改成UTF-8
那么,最简便的方法:对于window(修改my.ini配置文件),my.ini在哪里,如何修改成UTF-8如下:
https://www.cnblogs.com/Ray-xujianguo/p/3322455.html
对于mac平台(修改/etc/my.cnf配置文件),但事实却是我们在/etc下面没有my.cnf配置文件。这时候就要我们自己写一个my.cnf配置文件支持UTF-8
我们用vim 在/etc路径下新建一个my.cnf(记得用sudo命令哦),

sudo vim my.cnf

然后将如下代码拷贝到my.cnf里面:

# 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

# 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 format - mixed recommended

      # required unique id between 1 and 2^32 - 1  
      # defaults to 1 if master-host is not set  
      # but will not function as a master if omitted  
      server-id   = 1  

    # Replication Slave (comment out master section to use this)  
    #  
    # 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  
    #log-bin=mysql-bin  

      # Uncomment the following if you are using InnoDB tables  
      #innodb_data_home_dir = /usr/local/mysql/data  
      #innodb_data_file_path = ibdata1:10M:autoextend  
      #innodb_log_group_home_dir = /usr/local/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  
          default-character-set=utf8   

        [myisamchk]  
        key_buffer_size = 20M  
        sort_buffer_size = 20M  
        read_buffer = 2M  
        write_buffer = 2M  

          [mysqlhotcopy]  
          interactive-timeout

之后重启一下mysql服务
这里写图片描述
点下那个Stop MySQL Server,然后再点下就重启了。
一切弄完了。
进行mysql ,键入命令

mysql -u root -p. (这条命令是让你进入mysql的)
show variables like '%char%';

如下是以下结果就说明成功了:
这里写图片描述
这里要注意的是:如果你在改变字符集之前建的表。那么,它的字符集无法改变,你要再改变字符集之后重新建表才能解决这个问题

2.然后,我们解决python连接mysql的中文乱码问题:
对于python来说,只有一行代码修改字符集:

import sys
reload(sys)
sys.setdefaultencoding("utf-8")

以上,mysql+python的中文乱码问题就解决了。
