MariaDB服务器无法启动

我的MariaDB服务器出现了一些问题-它无法再启动。每次我尝试启动服务器时都失败了:

root# /etc/init.d/mysql start
[....] Starting mysql (via systemctl): mysql.service
Job for mysql.service failed. See 'systemctl status mysql.service' and 
'journalctl -xn' for details.
failed!

我已经试过了:

  • 重新启动整个系统
  • 重新启动mysql服务(正常和安全模式)-〉启动失败
  • 正在检查/var/lib/mysqld的权限
  • 重新安装MariaDB添加 innodb_force_recovery = 6 到我的.cnf

下面是我最近的日志文件:

This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.

To report this bug, see https://mariadb.com/kb/en/reporting-bugs

We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed, 
something is definitely wrong and this may fail.

Server version: 10.0.30-MariaDB-0+deb8u2
key_buffer_size=134217728
read_buffer_size=131072
max_used_connections=0
max_threads=153
thread_count=0
It is possible that mysqld could use up to 
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 465934 K  bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

Thread pointer: 0x0
Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong...
stack_bottom = 0x0 thread_stack 0x30000
The manual page at http://dev.mysql.com/doc/mysql/en/crashing.html contains
information that should help you find out what is causing the crash.
addr2line: 'mysqld': No such file

我不知道下一步该怎么做。我能找到的每一个恢复指南都只是备份了ibd* 文件和schematics目录,用 innodb_force_recovery = 6innodb_force_recovery = 4 启动服务器,然后一切又都正常了。
有人有主意吗?

我也遇到了同样的问题。请检查您的系统日期和时区信息。使用timedatectl命令。服务器I使用的是NTP,默认情况下是活动的。禁用NTP并正确设置日期和时区。重新启动它,一切都会好起来。希望这可能会有所帮助。

尝试使用innodb_force_recovery = 1并导出转储。expore完成后,在/var/lib/mysql中存储ib*-文件的副本并将其删除。之后,您应该可以在不使用innodb_force_recovery的情况下重新启动mariadb,并导入转储。

尝试从innodb_force_recovery = 1innodb_force_recovery = 6交替运行mysql。当mysql启动时,尝试mysqldump您的数据库并在测试节点上还原它。如果一切正常,则尝试在生产节点上还原转储,而不使用innodb_force_recovery参数。
恢复前备份**/var/lib/mysql**目录。
