清除mariadb，留下停止mysql安装的跟踪。

Question

我正在尝试用我正在开发的网站来测试数据库问题。我想看看mariadb和MySQL之间的切换是否解决了这个问题(尽管这是不太可能的)。我认为这将是开发机器上的一个简单进程(我不需要担心/备份任何数据)。

我用了命令

sudo apt-get purge mariadb*

然后我进去了

sudo apt-get install mysql-server

很惊讶地看到这个可爱的错误。

   invoke-rc.d: initscript mysql, action "start" failed.
dpkg: error processing mysql-server-5.5 (--configure):
 subprocess installed post-installation script returned error exit status 1
dpkg: dependency problems prevent configuration of mysql-server:
 mysql-server depends on mysql-server-5.5; however:
  Package mysql-server-5.5 is not configured yet.
dpkg: error processing mysql-server (--configure):
 dependency problems - leaving unconfigured
Setting up libmariadbclient18 (5.5.32+maria-1~precise) ...

 mysql-server
E: Sub-process /usr/bin/dpkg returned an error code (1)

我尝试了dkpg -配置-a，并受到了这样的欢迎。

Setting up mysql-server-5.5 (5.5.31-0ubuntu0.12.04.2) ...

我注意到有一行写着

setting up libmariadbclient18

这对我来说毫无意义，因为我之前清除了mariadb*。有谁知道发生了什么事吗？

最新消息--我直接谈到了问题的核心--

sudo apt-get install mysql-client-5.5

受到了欢迎

Note, selecting 'mariadb-client-5.5' instead of 'mysql-client-5.1'

不知道怎么回事。

update2

sudo apt-get purge libmariadbclient-dev

让我安装正确的客户端，在安装时仍然会出现错误。

Answer 1

您忘了删除libmariadbclient18包。先把它拿掉。

Answer 2

如果您可以卸载mysql-server并删除所有数据库，您可以尝试这样做(同样，请确保您已经对所有数据库进行了工作备份)：

rm -rf /var/lib/mysql

然后重新安装mysql服务器。
