无法在Ubuntu 14.04上安装Mysql 5.6

Question

我正在尝试在Ubuntu 14.04上从Mysql 5.5升级到Mysql 5.6

我试过了：

• 使用sudo apt-get直接安装mysql-server-5.6直接安装 -没有成功
• 首先根据此线程完全删除Mysql 5.5：完全删除MySQL 5.5，然后使用sudo apt-get安装mysql-server-5.6进行安装-没有成功
• 创建4g交换，如此处所述： https : //askubuntu.com/questions/457923/why-did-installation-of-mysql-5-6-on-ubuntu-14-04-fail-没有成功

这些选项都不起作用..我得到的错误是：

我无法设置它，真的很沮丧

在Digital Ocean VPS上运行，请高手指教我:(

Answer 1

似乎在配置文件中将“ innodb_buffer_pool_size”变量的大小设置得太小，因此请根据您的服务器RAM来增加它（您最多可以设置总RAM的80％），然后尝试...

Answer 2

在我遇到这种情况之前，我遇到了这个问题，因为我使用的是无业游民的vpc服务器。

1.remove all Local MySQL
$ sudo apt-get autoremove –purge mysql*
$ sudo rm -rf /var/lib/mysql/
$ sudo rm -rf /etc/mysql/

2.install mysql
$ sudo apt-get update
$ sudo apt-get build-dep mysql-server-5.6
$ sudo apt-get install mysql-server-5.6

如果仍然有问题，请检查以下信息：

1. 增加EC2中的内存量
2. 为MySQL的max_connections变量设置一个较小的值
