Ubuntu20.04安装MySQL 8.0.34全程记录

一、官网下载安装包准备安装

1.下载tar包MySQL :: Download MySQL Community Serverhttps://dev.mysql.com/downloads/mysql/

 找到下载链接，我直接下载到用户文件夹下。

~$ wget https://dev.mysql.com/get/Downloads/MySQL-8.0/mysql-server_8.0.34-1ubuntu20.04_amd64.deb-bundle.tar

2.解压缩tar包

~$ tar xf mysql-server_8.0.34-1ubuntu20.04_amd64.deb-bundle.tar

3.为解压后的文件设置权限

解压完后的deb包如果是红色的文字，说明没有执行权限，需要添加执行权限

 输入命令

~$ sudo chmod +x mysql*

~$ sudo chmod +x libmysqlclient*

文字变黑

 

二、开始安装（依次执行）

1.安装mysql-common包

~$ sudo dpkg -i mysql-common_8.0.34-1ubuntu20.04_amd64.deb

2.安装mysql-community-client-plugins包

~$ sudo dpkg -i mysql-community-client-plugins_8.0.34-1ubuntu20.04_amd64.deb

3.安装mysql-community-client-core包

~$ sudo  dpkg -i mysql-community-client-core_8.0.34-1ubuntu20.04_amd64.deb

4. 安装mysql-community-client包

~$ sudo dpkg -i mysql-community-client_8.0.34-1ubuntu20.04_amd64.deb

5.安装mysql-client包

~$ sudo dpkg -i mysql-client_8.0.34-1ubuntu20.04_amd64.deb

6.安装mysql-community-server-core和mysql-community-server包，若安装过程中提示缺少libaio1和libmecab2包，可以先下载安装libaio1和libmecab2包

sudo apt-get install libaio1
sudo apt-get install libmecab2

再依次安装mysql-community-server-core和mysql-community-server包。

sudo dpkg -i mysql-community-server-core_8.0.34-1ubuntu20.04_amd64.deb
sudo dpkg -i mysql-community-server_8.0.34-1ubuntu20.04_amd64.deb

或直接用sudo apt --fix-broken install修复安装libaio1和libmecab2包

~$ sudo apt --fix-broken install

使用该命令后，输入“y”，会同时安装mysql-community-server-core和mysql-community-server包

qs@qs-ubuntu:~$ sudo apt --fix-broken install

7.安装过程中弹出设置root密码界面，在输入框中设置root密码，这里忘记截图，按操作要求来即可。至此安装完成。

三、查看安装的MySQL版本，检测是否成功安装

1.查看版本

~$ mysql --version

2.登入mysql 

~$ mysql -uroot -p

安装成功。
