Mac下MySQL 更改UTF-8编码

网上很多都不好用,所以特发了一篇教程.
Mac下mysql是没有my.ini文件的,这是windows的配置文件.Mac下的配置文件为my.cnf.需要我们在/private/etc/下手动创建

1.进入/etc/文件夹

cd /etc/

2.通过vim按i进入insert模式编辑my.cnf

sudo vim my.cnf

3.复制下列代码,按esc,输入:wq保存即可

或者可以直接创建一个my.cnf文件,复制下列代码,保存以后

右键Finder前往/private/etc/下,将my.cnf文件复制过去

# 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 is required for replication

# binary logging format - mixed recommended 
binlog_format=mixed

# 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=, MASTER_PORT=, 
# MASTER_USER=, MASTER_PASSWORD= ; 
# 
# where you replace , ,  by quoted strings and 
#  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 =  
# 
# The username the slave will use for authentication when connecting 
# to the master - required 
#master-user =  
# 
# The password the slave will authenticate with when connecting to 
# the master - required 
#master-password =  
# 
# The port the master is listening on. 
# optional - defaults to 3306 
#master-port =  
# 
# binary logging - not required for slaves, but recommended
