mysql安装设置编码_MySQL安装之编码设置的图文详解

一、MySQL的安装

从官网中下载Mac OS X 10.12 (x86, 64-bit), DMG Archive(mysql-5.7.19-macos10.12-x86_64.dmg)版，双击按提示安装，安装完成后可在控制面板下启动关闭MySQL服务器，

同时安装客户端：MySQL Workbench.app，

启动MySQL服务器，打开MySQL Workbench，输入初始密码，随即提示修改初始密码。

二、设置Terminal下登录路径：

在/Users/**/新建文件：.bash_profile

文件中输入：export PATH=${PATH}:/usr/local/mysql/bin

保存即可。在Terminal下，即可使用"mysql -u root -p"进行登录。

三、数据库编码问题

在Terminal中登录MySQL客户端(mysql -u root -p)查看数据库编码，命令如下：mysql> SHOW VARIABLES LIKE 'char%';

发现character_set_database | latin1

character_set_server | latin1

需要进行编码设置，但安装文件里无my.cnf文件，网上很多解决方法都没用，只能自建my.cnf文件。

关闭MySQL服务器，使用MacVim创建my.cnf,输入内容为：# 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

# 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

# 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=, 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.

# optional - defaults to 3306

#master-port =

保存并将文件存在至/etc/目录之下，重启mysql服务器，即修改成功，

如果还是不能插入汉字，请重新创建数据库和表。
