Configuring mysql-apt-config

\----------------------------

MySQL APT Repo features MySQL Server along with a variety of MySQL components. You may select the appropriate product to choose the version

that you wish to receive.

Once you are satisfied with the configuration then select last option 'Ok' to save the configuration, then run 'apt-get update' to load

package list. Advanced users can always change the configurations later, depending on their own needs.

1. MySQL Server & Cluster (Currently selected: mysql-8.0) 3. MySQL Preview Packages (Currently selected: Disabled)

2. MySQL Tools & Connectors (Currently selected: Enabled) 4. Ok

Which MySQL product do you wish to configure? 1

This configuration program has determined that mysql-8.0 is configured on your system, and has highlighted the most appropriate repository

package. If you are not sure which version to install, do not change the auto-selected version. Advanced users can always change the

version as needed later. Note that MySQL Cluster also contains MySQL Server.

1. mysql-5.7 2. mysql-8.0 3. mysql-cluster-7.5 4. mysql-cluster-7.6 5. mysql-cluster-8.0 6. None

Which server version do you wish to receive? 2

apt-get update \#更新mysql源

注意看一下是否更新成功，有时候会出现connect time out,多试几次就可以了

apt-get install mysql-server \#安装mysql

输入密码 123456

确认密码 123456

选 1. Use Strong Password Encryption (RECOMMENDED) \#选择1强密码加密

安装完成后，官网说直接使用service就可以启动，service mysql start,但是我这里报找不到这个service启动脚本。

因为在/etc/init.d/目录里没有这个mysql的启动命令

使用mysqld来启动，直接使用mysqld命令启动，报错不允许使用root用户执行

\[Server\] Fatal error: Please read "Security" section of the manual to find out how to run mysqld as root!

使用mysql用户执行

mysqld --user=mysql & \#启动并后台运行

ps aux | grep mysql \#查看已经启动了mysqld

kill 进程号可以停止mysql服务

mysql -uroot -p

输入密码123456

show databases; \#查看现有的库

root@7c609eaf61d3:/etc/init.d\# mysql -uroot -p

Enter password:

到此已经成功安装上8.0.21 MySQL
