mac終端下修改MySQL的編碼格式--找不到my-default.cnf及my.cnf

標籤：資料庫   root   2.4   sam   mit   file   extend   ack   required   

　首先請確認正確安裝好MySQL.

　　1- 先配置環境變數path

　　　　1.1 開啟終端,輸入： cd ~

　　　　　　會進入~檔案夾,

　　　　1.2 然後輸入：touch .bash_profile

　　　　　　斷行符號執行後,

　　　　1.3 再輸入：open -e .bash_profile

　　　　　　會在TextEdit中開啟這個檔案(如果以前沒有配置過環境變數,那麼這應該是一個空白文檔).

　　　　　　如果有內容,請在結束符前輸入,如果沒有內容,請直接輸入如下語句:

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

　　　　　　然後,儲存,退出TextEdit(一定是退出),關閉終端並退出.

　　　　　　此時應該可以直接用以下語句登入MySQL了

　　　　　　>mysql -uroot -p 

　　　　1.4 關閉MySQL  !!!!(在系統喜好設定裡面關閉MySQL)

　　2- 重點來了!!!

　　　　2.1 查看一下support-files檔案夾(Finder下"前往檔案夾";路徑:/usr/local/mysql/support-files)

　　　　　　　　裡面有沒有my-default.cnf或my.cnf檔案...如果有則直接開啟添加

　　　　　　在[client] 在下面添加　　　　　　default-character-set=utf8 預設字元集為utf8 
　　　　　　在[mysqld] 添加 
　　　　　　default-character-set=utf8 預設字元集為utf8 
 　　　　　　init_connect=‘SET NAMES utf8‘ （設定串連mysql資料庫時使用utf8編碼，以讓mysql資料庫為utf8運行）　　　　　　修改好後，重新啟動mysql查看當前資料編碼格式。 >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/ | 
 +--------------------------+----------------------------+

　　　　若終端出現如上樣式則OK了,否則繼續往下看:

　　　　2.2 support-files檔案夾裡面沒有my-default.cnf或my.cnf檔案,那麼就要在/etc下建立my.cnf

　　　　　　$ cd /etc

　　　　　　$ sudo vim my.cnf

　　　　2.3 進行完上步操作後會進入vim模式,此時複製(***文本)的內容粘貼進去,,(不包含   ***文本 );

　　　　2.4 粘貼成功後注意看vim的第一行"#"有沒有丟掉(本人就丟過~~哈哈~),都OK的話點esc退出編輯,

　　　　　　:wq!     --儲存後強制退出.[附幾個編輯命令:dd   刪除游標所在行; dw   刪除一個字(word); x   刪除當前字元].

# 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]

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

# Replication Master Server (default)

# binary logging format - mixed recommended

# defaults to 1 if master-host is not set
# but will not function as a master if omitted

# 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
