首先著蛙，請確認(rèn)正確安裝好MySQL删铃。
一、配置環(huán)境變量path（可跳過）
1.1 打開終端,輸入：cd ~ 會進(jìn)入 ~文件夾
? ? ? ?1.2?然后輸入：touch .bash_profile 回車執(zhí)行后
? ? ? ?1.3 再輸入：open -e .bash_profile 會在TextEdit中打開這個文件（如果以前沒有配置過環(huán)境變量,那么這應(yīng)該是一個空白文檔）踏堡。如果有內(nèi)容猎唁，請在結(jié)束符前輸入，如果沒有內(nèi)容暂吉，請直接輸入如下語句：export PATH=${PATH}:/usr/local/mysql/bin 然后，保存（control + x缎患，y）退出TextEdit（一定是退出）慕的，關(guān)閉終端并退出。此時應(yīng)該可以直接用以下語句登入MySQL了挤渔。
? ? ? ? >mysql -uroot -p
二肮街、配置my-default.cnf / my.cnf
? ? ? ? 2.1 查看一下support-files文件夾（Finder下"前往文件夾"；路徑:/usr/local/mysql/support-files 可以在終端里輸入 open /usr/local/mysql/support-files 直接打開）里面有沒有my-default.cnf或my.cnf文件判导；如果有則直接打開嫉父。
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)庫時使用utf8編碼，以讓mysql數(shù)據(jù)庫為utf8運(yùn)行）
修改好后眼刃，重新啟動mysql查看當(dāng)前數(shù)據(jù)編碼格式绕辖。
（查看當(dāng)前數(shù)據(jù)編碼格式）>mysql 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：
2.2?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
2.3 進(jìn)行完上步操作后會進(jìn)入vim模式,此時復(fù)制(***文本)的內(nèi)容粘貼進(jìn)去,,(不包含 ? ***文本 )文本內(nèi)容如下；
2.4 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退出編輯擂红，:wq!--保存后強(qiáng)制退出仪际。
[附幾個編輯命令：dd刪除光標(biāo)所在行；dw刪除一個字(word)；x刪除當(dāng)前字符]树碱。

# 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

# 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 =
