mac终端下改过MySQL的编码格式–找不到my-default.cnf及my.cnf,找不到mydefault.cnf

mac终端下改进MySQL的编码格式–找不到my-default.cnf及my.cnf,找不到mydefault.cnf

 首先请确认精确安装好MySQL.

  1- 先配置情形变量path

    1.1 展开终端,输入: cd ~

      会进入~文件夹,

    1.2 然后输入:touch .bash_profile

      回车实施后,

    1.3 再输入:open -e .bash_profile

      会在TextEdit中开拓那个文件(即使原先不曾安顿过意况变量,那么这应该是三个赤手文书档案卡塔尔(英语:State of Qatar).

      尽管有内容,请在得了符前输入,若无内容,请直接输入如下语句:

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

      然后,保存,退出TextEdit(一定是脱离卡塔尔,关闭终端并退出.

      这时候应当能够一直用来下语句登录MySQL了

      >mysql -uroot -p 

    1.4 关闭MySQL  !!!!(在系统偏爱设置里面关闭MySQL卡塔尔(قطر‎

  2- 注重来了!!!

    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卡塔尔

        里面有未有my-default.cnf或my.cnf文件…如果有则一向展开增添

      在[client] 在上面增添      default-character-set=utf8 私下认可字符集为utf8 
      在[mysqld] 添加 
      default-character-set=utf8 暗中同意字符集为utf8 
       init_connect=’SET NAMES utf8′
(设定连接mysql数据库时行使utf8编码,以让mysql数据库为utf8运作)
      校订好后,重新启航mysql查看当前数据编码格式。   >show
variables like ‘%char%’; 
+————————–+—————————-+ 
| Variable_name | Value | 
+————————–+—————————-+ 
| character_set_client | utf8 | 
| character_set_connection | utf8 | 
| character_set_database | utf8 | 
| character_set_filesystem | binary | 
| character_set_results | utf8 | 
| character_set_server | utf8 | 
| character_set_system | utf8 | 
| character_sets_dir | /usr/share/mysql/charsets/ | 
 +————————–+—————————-+

    若终端现身如上样式则OK了,不然继续往下看:

    2.2 support-files文件夹里面未有my-default.cnf或my.cnf文件,那么将要在/etc下新建my.cnf

      $ cd /etc

      $ sudo vim my.cnf

    2.3
进行完上步操作后会步入vim格局,当时复制(***文本卡塔尔的内容粘贴进去,,(不满含  ***文本 );

    2.4
粘贴成功后专心看vim的第大器晚成行”#”有未有丢掉(本人就丢过~~哈哈~卡塔尔(قطر‎,都OK的话点esc退出编辑,

      :wq!     –保存后强制退出.[附多少个编辑命令:dd  
删除光标所在行; dw   删除二个字(word卡塔尔国; 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:
#
#
# 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]

# 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

# Replication Master Server (default)

# defaults to 1 if master-host is not set

# 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
