(Mac)項(xiàng)目中編碼都是UTF-8,MySQL還是中文亂碼解決辦法

原因:修改mysql的默認(rèn)編碼不是UTF-8的

修改辦法:修改mysql的默認(rèn)字符集為utf8

方法:

1,檢查默認(rèn)安裝的mysql的字符集

mysql> show variables like '%char%';

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

| Variable_name ? ? ? ? ? ?| Value ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?|

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

| character_set_client ? ? | utf8 ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? |

| character_set_connection | utf8 ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? |

| character_set_database ? | latin1 ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? |

| character_set_filesystem | binary ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? |

| character_set_results ? ?| utf8 ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? |

| character_set_server ? ? | latin1 ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? |

| character_set_system ? ? | utf8 ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? |

| character_sets_dir ? ? ? | /usr/local/mysql-5.5.23-osx10.6-x86_64/share/charsets/ |

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

character_set_database和character_set_server依然是latin1的字符集,也就是說mysql后續(xù)創(chuàng)建的表都是latin1字符集的,不是utf8,會(huì)造成一些麻煩。所以有必要修改my.cnf,在修改my.cnf之前一定要關(guān)閉mysql進(jìn)程,不然會(huì)遇到mysql的sock不能連接的問題。

2,關(guān)閉mysqld后臺(tái)進(jìn)程

系統(tǒng)偏好設(shè)置里面控制mysqld,避免了去找mysqld安裝位置的麻煩。





點(diǎn)擊 Stop MySQL Server

3,查看一下support-files文件夾(Finder下"前往文件夾";路徑:/usr/local/mysql/support-files) 里面有沒有my-default.cnf或my.cnf文件...如果有則直接打開添加

在[client] 在下面添加

default-character-set=utf8 默認(rèn)字符集為utf8

在[mysqld] 添加

default-character-set=utf8 默認(rèn)字符集為utf8

init_connect='SET NAMES utf8' (設(shè)定連接mysql數(shù)據(jù)庫時(shí)使用utf8編碼,以讓mysql數(shù)據(jù)庫為utf8運(yùn)行)

      修改好后,重新啟動(dòng)mysql查看當(dāng)前數(shù)據(jù)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(xiàn)如上樣式則OK了,否則繼續(xù)往下看:

    3.2 support-files文件夾里面沒有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

    3.3 進(jìn)行完上步操作后會(huì)進(jìn)入vim模式,此時(shí)復(fù)制(***文本)的內(nèi)容粘貼進(jìn)去,,(不包含 ? ***文本 );

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

:wq!?--保存后強(qiáng)制退出.[附幾個(gè)編輯命令:dd?刪除光標(biāo)所在行;dw?刪除一個(gè)字(word);x?刪除當(dāng)前字符].

# 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??

# 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=, MASTER_PORT=,??

# MASTER_USER=, MASTER_PASSWORD= ;??

#??

# where you replace , , by quoted strings and??

# 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 = ??

#??

# The username the slave will use for authentication when connecting??

# to the master - required??

#master-user = ??

#??

# The password the slave will authenticate with when connecting to??

# the master - required??

#master-password = ??

#??

# The port the master is listening on.??
