安装

双击下载好的dmg文件，会弹出pkg弹框，再双击pkg图标，进入安装界面，在安装界面上一路继续，就安装成功了。

环境变量

第一步，在终端切换到根目录，编辑./.bash_profile文件

➜  ~ cd ~➜  ~ vim ./.bash_profile

第二步，进入vim编辑环境，按下i进入insert模式，输入

export PATH=$PATH:/usr/local/mysql/binexport PATH=$PATH:/usr/local/mysql/support-files

第三步，按下 esc 退出 insert 模式，输入 :wq 保存配置文件

:wq

第四步，在终端界面输入以下命令，让配置文件的修改生效，并查看环境变量是否设置成功

➜  ~ echo $PATH/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin➜  ~ source ~/.bash_profile ➜  ~ echo $PATH            /usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/mysql/bin:/usr/local/mysql/support-files➜  ~

MYSQL服务的启停和状态的查看

查看MYSQL的服务状态

➜  ~ sudo mysql.server statusPassword: ERROR! MySQL is not running

启动MYSQL服务

➜  ~ sudo mysql.server start Starting MySQL.Logging to '/usr/local/mysql/data/mj.local.err'. SUCCESS!

停止MYSQL服务

➜  ~ sudo mysql.server stop  Shutting down MySQL. SUCCESS!

重启MYSQL服务

➜  ~ sudo mysql.server restart ERROR! MySQL server PID file could not be found!Starting MySQL. SUCCESS!

启动

第一步，终端界面下输入

➜  ~ sudo mysql.server start Starting MySQL.Logging to '/usr/local/mysql/data/mj.local.err'. SUCCESS!

第二步，启动MYSQL服务，启动成功后继续输入

➜  ~ mysql -u root -p

第三步，直接回车，进入数据库，看到以下欢迎界面

Enter password: Welcome to the MySQL monitor.  Commands end with ; or \g.Your MySQL connection id is 1Server version: 5.6.41 MySQL Community Server (GPL)Copyright (c) 2000, 2018, Oracle and/or its affiliates. All rights reserved.Oracle is a registered trademark of Oracle Corporation and/or itsaffiliates. Other names may be trademarks of their respectiveowners.Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.mysql>

备注：默认安装成功后没有初始密码，所以密码不用输入，直接回车即可。

初始化设置

设置初始密码，进入mysql数据库之后执行下面的语句，设置当前root用户的密码为root

➜  ~ mysql -u root -pEnter password: Welcome to the MySQL monitor.  Commands end with ; or \g.Your MySQL connection id is 2Server version: 5.6.41 MySQL Community Server (GPL)Copyright (c) 2000, 2018, Oracle and/or its affiliates. All rights reserved.Oracle is a registered trademark of Oracle Corporation and/or itsaffiliates. Other names may be trademarks of their respectiveowners.Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.mysql> set password = password('root');Query OK, 0 rows affected (0.01 sec)mysql>

退出MYSQL的界面

mysql> exitBye➜  ~

配置

进入到 /usr/local/mysql/support-files目录，里面有个文件my-default.cnf

➜  ~ cd /usr/local/mysql/support-files➜  support-files lltotal 64-rwxr-xr-x  1 root  wheel   1.1K  6 15  2018 binary-configure-rw-r--r--  1 root  wheel   773B  6 15  2018 magic-rw-r--r--  1 root  wheel   1.1K  6 15  2018 my-default.cnf-rwxr-xr-x  1 root  wheel   894B  6 15  2018 mysql-log-rotate-rwxr-xr-x  1 root  wheel    10K  6 15  2018 mysql.server-rwxr-xr-x  1 root  wheel   1.0K  6 15  2018 mysqld_multi.server➜  support-files

将目录下的my-default.cnf文件复制到桌面上，改名为my.cnf，

➜  support-files lltotal 64-rwxr-xr-x  1 root  wheel   1.1K  6 15  2018 binary-configure-rw-r--r--  1 root  wheel   773B  6 15  2018 magic-rw-r--r--  1 root  wheel   1.1K  6 15  2018 my-default.cnf-rwxr-xr-x  1 root  wheel   894B  6 15  2018 mysql-log-rotate-rwxr-xr-x  1 root  wheel    10K  6 15  2018 mysql.server-rwxr-xr-x  1 root  wheel   1.0K  6 15  2018 mysqld_multi.server➜  support-files cp my-default.cnf /Users/a1/Desktop/my.cnf

将内容替换为下面的内容

[mysqld]default-storage-engine=INNODBcharacter-set-server=utf8port = 3306[client]default-character-set=utf8

将修改后的my.cnf文件复制到/etc目录下，重启MYSQL

➜  /etc cp /Users/a1/Desktop/my.cnf ./cp: ./my.cnf: Permission denied➜  /etc sudo cp /Users/a1/Desktop/my.cnf ./Password:➜  /etc lltotal 1064......-rw-------   1 root  wheel   7.3K  2 29 14:10 master.passwd-rw-r--r--   1 root  wheel   1.2K  5 17 17:24 my.cnf-rw-r--r--   1 root  wheel    11B  2 29 14:43 nanorc-rw-r--r--   1 root  wheel    53B  2 29 14:09 networks......➜  /etc

备注：拷贝文件到etc目录需要系统权限，因此需要在命令前加sudo

检测修改结果

备注：此时不输入密码就登录不了数据库了，必须使用修改后的密码登录数据库了，并且数据库的字符集编码信息已经修改了。
