mac os x mysql数据库utf8配置

 

进入mysql console:

输入

mysql>show variables like 'character%';

 

 

+--------------------------+-----------------------------------------------------+

| Variable_name            | Value                                               |

+--------------------------+-----------------------------------------------------+

mysql>show variables like 'coll%';

+----------------------+-----------------+

| Variable_name        | Value           |

+----------------------+-----------------+

| collation_connection | utf8_general_ci | 

| collation_database   | utf8_general_ci | 

| collation_server     | utf8_general_ci | 

+----------------------+-----------------+

如果有的项目不是utf8，我们需要进行设置

编辑/etc/my.cnf，如果没有该文件，从mysql的安装目录的support-files copy一个my-small.cnf到/etc下，更名为my.cnf

sudo cp /usr/local/mysql/support-files/my-medium.cnf /etc/my.cnf

sudo vi /etc/my.cnf

加入红色字体的部分，保存后，重启mysql，重新执行show命令，将会发现应该都是utf8

注意default-character-set = utf8，等号两边要有空格，很重要，不然配置文件不生效

 

 

 

 

# 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.

#

# You can copy this file to

# /etc/my.cnf to set global options,

# mysql-data-dir/my.cnf to set server-specific options (in this

# installation this directory is /usr/local/mysql/data) or

# ~/.my.cnf to set user-specific options.

#

# 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]

#password = your_password

# Don't listen on a TCP/IP port at all. This can be a security enhancement,

# All interaction with mysqld must be made via Unix sockets or named pipes.

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