无法在 Ubuntu 12.04 中安装 MariaDB 5.5 或 10。MYSQLD 启动失败？

Question

我尝试在我的 Ubuntu 12.04 服务器上安装 MariaDB。首先它给出了依赖性问题，我通过以下问题解决了它：https : //stackoverflow.com/questions/16214517/installing-mariadb-unmet-dependencies-mariadb-server-5-5

但是在安装mariadb-server时，启动mysqld失败。这是 apt 日志：

尝试重新安装 mariadb-server，清除所有内容...删除 mysql 软件包，安装 mariadb-server-5.5... 没有任何效果。

Answer 1

这对我有用：

sudo apt-get purge mysql* mariadb*

Answer 2

刚刚通过清除 mysql* 和 mariadb* 解决了问题。然后通过搜索删除所有mysql痕迹：

find / -name mysql*

lib 里还有一些剩菜。删除它们后，重新启动服务器并再次安装 mariadb！有效。
