修改mysql编码为utf-8

下面的操作都是在Mac系统下进行的，每个步骤都是我做过的。亲测有效。

1. 打开命令行，查看当前mysql编码状态

SHOW VARIABLES LIKE 'character%';

如下图：

2. 打开finder，进入etc文件夹

在finder界面，按住shift+command+g，就会出现下图界面，在输入框中输入/etc:

3. 在etc文件夹内，查看是否有my.cnf文件，打开并用下面的内容覆盖它。如果没有，就新建一个，然后把下面的内容复制进去。

# 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]  
default-character-set=utf8  
#password   = your_password  
port        = 3306 
socket      = /tmp/mysql.sock  
 
# Here follows entries for some specific programs  
 
# The MySQL server   
[mysqld]

read_rnd_buffer_size = 256K  
net_buffer_length = 2K  
thread_stack = 128K  
 
# 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 = /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  
 
[myisamchk]  
key_buffer_size = 8M  
sort_buffer_size = 8M  
 
[mysqlhotcopy]  
interactive-timeout 

4. 重启mysql

5. 再次进入命令行，输入之前的命令

SHOW VARIABLES LIKE 'character%';

如果看到下图所示，就成功了。
