哪个命令返回MySQL数据库的当前版本?
当前回答
这里还有两个方法:
Linux: Mysql视图版本:从PHP
从PHP函数中，我们可以看到使用的版本:
mysql_get_server_info ([resource $ link_identifier = NULL]): string
Linux: Mysql view version:包的版本号
对于RedHat / CentOS操作系统:
rpm -qa | grep mysql
对于Debian / Ubuntu操作系统:
rpm -qa | grep mysql

使用mysql -V对我来说在Ubuntu上很好。
有时候，知道默认安装的MySQL候选版本是可用的是很重要的。下面是在实际安装之前检查的小命令。
sudo apt-cache policy mysql-server
这对于任何可能运行在旧MySQL版本(如5.7)上的现有项目都更重要。
上面命令的示例输出可以是:
mysql-server: Installed:(none) 8.0.29-0ubuntu0.20.04.3版本表: 8.0.29-0ubuntu0.20.04.3 500 500 http://mirrors.digitalocean.com/ubuntu focal-updates/main amd64 软件包500 http://security.ubuntu.com/ubuntu focus -security/main amd64包 8.0.19-0ubuntu5 500 500 http://mirrors.digitalocean.com/ubuntu focal/main amd64包
这说明在默认情况下，通过运行以下命令将安装一些MySQL Server 8。
sudo apt install mysql-server
您还可以在第一次登录时查看MySQL shell的顶部。它实际上在这里显示了版本。
