mac上mysql.tar.gz的安装图解

本文主要讲述mac下5.6/5.7/8.0用tar.gz方式安装的mysql数据库，并晒出简单的shell脚本和执行方式，自测可以通过

主要功能点：

mysql-install.sh:安装，配置环境变量，开机自启动，修改默认密码

mysql-config.sh:建库，使用sql文件还原，创建用户和授权

mysql-backup.sh:备份，清楚历史备份

版本：

mac---macOS Mojave 10.14 18A391 Lazy Installer.cdr

mysql 5.6---5.6.33

mysql 5.7---5.7.31

mysql 8.0---8.0.22

使用说明：

1-下载下来的tar.gz文件需要先解压，然后重新命名为mysql.tar.gz

2-5.7和8.0版本需要预先在mysql文件夹下创建data的文件夹

3-解压脚本：

例如5.7版本的tar.gz文件：

解压到tar.gz包的同级目录下：

 sudo tar xvf mysql-5.7.31-macos10.14-x86_64.tar.gz

修改文件夹名称：

sudo mv mysql-5.7.31-macos10.14-x86_64 mysql

如果5.7和8.0版本需要在mysql文件夹下创建data目录

切入mysql文件夹下

sudo mkdir data

注意：切到mysql的同级目录下，然后压缩文件夹

sudo tar cvf mysql.tar.gz mysql

4-下载

https://downloads.mysql.com/archives/community/

5.6

5.7

8.0

5-文件列表

mysql-install.sh：安装脚本，需要com.oracle.oss.mysql.mysqld.plist，my.cnf，mysql.tar.gz等文件（mysql.tar.gz为安装文件，my.cnf为配置文件，com.oracle.oss.mysql.mysqld.plist为开机自启动脚本）

执行方式：

sudo ./mysql-install.sh

执行结果：

mysql-config.sh:配置文件，需要sql文件（.sql文件为还原数据库的sql，不包括创建用户和授权）

执行方式：

sudo ./mysql-config.sh

执行结果：

mysql-backup.sh:备份文件，备份结果在该脚本所在目录

执行方式：

sudo ./mysql-backup.sh

执行结果：

脚本放送：
