今天我运行了apt-get upgrade

这简直是一场噩梦,我再也无法访问数据库了。我尝试过删除并清除数据库,然后重新安装,但总是出现相同的错误。
据此/var/log/syslog
与套接字和 mysqld 有关(运行后service mysql restart
):
mysqld: 151127 11:51:07 [ERROR] mysqld got signal 11 ;
...
mysqld_safe: mysqld from pid file /var/run/mysqld/mysqld.pid ended
/etc/init.d/mysql[14132]: 0 processes alive and '/usr/bin/mysqladmin --defaults-file=/etc/mysql/debian.cnf ping' resulted in
/etc/init.d/mysql[14132]: #007/usr/bin/mysqladmin: connect to server at 'localhost' failed

/etc/init.d/mysql[14132]: Check that mysqld is running and that the socket: '/var/run/mysqld/mysqld.sock' exists!
嗯,/var/run/mysqld/mysqld.sock
确实存在。另外,我不确定为什么它提到使用/etc/mysql/debian.cnf
- 我的主要 mysql 配置文件实际上应该是/etc/mysql/my.cnf
,不是吗?我真的没有主意了,任何新的想法都会很感激!
更新(2015-12-11)
仍然不知道问题是什么,升级仍然无效,仍然给出相同的错误。就像一些(现已删除)答案所说的那样,唯一的解决方案是回滚到服务器的旧快照。幸运的是,保存数据库就像将所有内容复制/var/lib/mysql
到另一个快照一样简单。
我希望有或者将会有解决这个问题的方法,因为我在 Google 上找不到适合我的东西。
答案1
以下是我解决问题的方法,我没有服务器的备份,因此我对 MariaDB 进行了“硬重置”:
首先,我备份了我的/var/lib/mysql
文件夹:我假设我有一个/home/ubuntu
文件夹并将该文件夹复制到那里。
cp -r /var/lib/mysql /home/ubuntu/
其次,我备份了我的/etc/mysql
文件夹:我假设我有一个/home/ubuntu
文件夹并将该文件夹复制到那里。
mkdir /home/ubuntu/etc_mysql
cp -r /etc/mysql /home/ubuntu/etc_mysql
然后我删除了/var/lib/mysql
和/etc/mysql
文件夹
rm -rf /etc/mysql
rm -rf /var/lib/mysql
之后,我清除了 MariaDB:
apt-get purge mariadb-server mariadb-* mysql-*
apt-get autoremove
清除后,我重新安装mariadb-server
并重新配置它:
apt-get install mariadb-server
mysql_secure_installation
从文件夹复制您需要的任何配置/home/ubuntu/etc_mysql
。
之后,我从mysql
cli 创建了数据库和用户(或者你想要的)
最后,我将/home/ubuntu/mysql/**databaseName**
文件夹复制到/var/lib/mysql/**databaseName**
cp -r /home/ubuntu/mysql/databaseName /var/lib/mysql/
然后,我就可以访问我的数据而不会造成任何丢失,就像我离开时一样。
