Ubuntu 怎么安装mysql5.7

Posted 2023-04-05

先安装好操作系统 　　在mysql官网上下载最新版的Ubuntu Linux专用的Mysql。我这里下载的是：mysql-server_5.7.11-1ubuntu14.04_amd64.deb-bundle.tar。 　　解压文件 命令为：tar -xvf mysql-server_5.7.11-1ubuntu14.04_amd64.deb-bundle.tar. 　　解压开来后，一共有11个deb包，用sudo dpkg -i [包名]命令逐个安装，因为包与包中间存在依赖关系，这里安装有个先后顺序。 　　我的安装的顺序是： 　　1.mysql-common_5.7.11-1ubuntu14.04_amd64.deb 　　2.libmysqlclient20_5.7.11-1ubuntu14.04_amd64.deb 　　3.libmysqlclient-dev_5.7.11-1ubuntu14.04_amd64.deb 　　4.libmysqld-dev_5.7.11-1ubuntu14.04_amd64.deb 　　5而后需要安装一个依赖包叫libaio1，命令为sudo apt-get intall libaio1; 　　而后继续： 　　5.mysql-community-client_5.7.11-1ubuntu14.04_amd64.deb 　　6.mysql-client_5.7.11-1ubuntu14.04_amd64.deb 　　7.mysql-community-source_5.7.11-1ubuntu14.04_amd64.deb 　　6 　　这里需要再安装一个依赖包叫libmecab2,安装好后，继续安装最后一个： 　　8.mysql-community-server_5.7.11-1ubuntu14.04_amd64.deb 　　安装过程中需要设置数据库密码。 　　到这里，所有的已经安装完毕。输入Mysql -uroot-p可以登陆数据库了。 参考技术A 　　sudo apt-get update
sudo apt-get upgrade
apt-get install libaio1
(apt-get install mysql-server mysql-client自动安装会装上5.5)
