1.官网下载dmg文件 版本 5.7.22
https://dev.mysql.com/downloads/mysql/
2.直接双击解压安装
按照步骤，直接点击下一步即可。
3.苹果->系统偏好设置->最下边点mysql 在弹出页面中 关闭mysql服务（点击stop mysql server）
4.进入终端输入：cd /usr/local/mysql/bin/
回车后 登录管理员权限 sudo su
输入你刚激活电脑设置的密码
回车后输入以下命令来禁止mysql验证功能 ./mysqld_safe --skip-grant-tables &
回车后mysql会自动重启（偏好设置中mysql的状态会变成running）
5.输入命令 ./mysql
回车后，输入命令 FLUSH PRIVILEGES;
回车后，输入命令 SET PASSWORD FOR 'root'@'localhost' = PASSWORD('你的新密码');
6.若支持命令界面输入,需要进行如下设置:
1>配置环境变量
$ cd ~
$ vim ./.bash_profile
进入vim 编辑环境。
按下i 进入 insert 模式
输入
export PATH=$PATH:/usr/local/mysql/bin
按下esc 退出 insert 模式
输入
:wq
保存配置文件。
在终端界面下输入
source ~/.bash_profile echo $PATH
查看系统环境变量是否设置成功。
终端界面下输入
sudo /usr/local/mysql/support-files/mysql.server start
启动mysql服务,启动成功后继续输入
mysql -u root -p
再输入数据库密码
查看字符编码
mysql> show variables like '%character%';
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-5.7.22-macos10.13-x86_64/share/charsets/
修改字符编码为utf-8
首先设置步骤如下:
先退出mysql,进行关闭
mysql> exit
$ sudo /usr/local/mysql/support-files/mysql.server stop
sudo vi /etc/my.cnf
并创建my.conf文件,粘贴如下内容，esc :wq保存并退出。
# Example MySQL config file for small systems. # # This is for a system with little memory (<= 64M) where MySQL is only used # from time to time and it's important that the mysqld daemon # doesn't use much resources. # # 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 [mysqld] default-storage-engine=INNODB character-set-server=utf8 collation-server=utf8_general_ci port = 3306 socket = /tmp/mysql.sock skip-external-locking key_buffer_size = 16K max_allowed_packet = 1M table_open_cache = 4 sort_buffer_size = 64K read_buffer_size = 256K read_rnd_buffer_size = 256K net_buffer_length = 2K thread_stack = 128K # Don't listen on a TCP/IP port at all.

最后打开终端，重启mysql服务，并查看字符集
$ sudo /usr/local/mysql/support-files/mysql.server start
mysql> show variables like '%character%';
