mac终端下修改MySQL的编码格式--找不到my-defaul…

　首先请确认正确安装好MySQL.

　　1- 先配置环境变量path

　　　　1.1 打开终端,输入： cd ~

　　　　　　会进入~文件夹,

　　　　1.2 然后输入：touch .bash_profile

　　　　　　回车执行后,

　　　　1.3 再输入：open -e .bash_profile

　　　　　　会在TextEdit中打开这个文件(如果以前没有配置过环境变量,那么这应该是一个空白文档).

　　　　　　如果有内容,请在结束符前输入,如果没有内容,请直接输入如下语句:

　　　　　　export PATH=${PATH}:/usr/local/mysql/bin

　　　　　　然后,保存,退出TextEdit(一定是退出),关闭终端并退出.

　　　　　　此时应该可以直接用以下语句登入MySQL了

　　　　　　>mysql -uroot -p 

　　　　1.4 关闭MySQL  !!!!(在系统偏好设置里面关闭MySQL)

　　2- 重点来了!!!

　　　　2.1 查看一下support-files文件夹(Finder下"前往文件夹";路径:/usr/local/mysql/support-files)

　　　　　　　　里面有没有my-default.cnf或my.cnf文件...如果有则直接打开添加

　　　　若终端出现如上样式则OK了,否则继续往下看:

　　　　2.2 support-files文件夹里面没有my-default.cnf或my.cnf文件,那么就要在/etc下新建my.cnf

　　　　　　$ cd /etc

　　　　　　$ sudo vim my.cnf

　　　　2.3 进行完上步操作后会进入vim模式,此时复制(***文本)的内容粘贴进去,,(不包含   ***文本 );

　　　　2.4 粘贴成功后注意看vim的第一行"#"有没有丢掉(本人就丢过~~哈哈~),都OK的话点esc退出编辑,

　　　　　　:wq!     --保存后强制退出.[附几个编辑命令:dd   删除光标所在行; dw   删除一个字(word); x   删除当前字符].

# 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
port = 3306
socket = /tmp/mysql.sock
# Here follows entries for some specific programs
# The MySQL server
[mysqld]
character-set-server=utf8
init_connect='SET NAMES utf8

# 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 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
