MariaDB 服务器无法启动

Question

我的 MariaDB 服务器有一些问题 - 它不再启动。 每次我开始尝试启动它失败的服务器：

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!

我已经尝试过了：

• 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
• 检查 /var/lib/mysqld 的权限
• 重新安装 MariaDB 将innodb_force_recovery = 6添加到 my.cnf

这是我的最新日志文件：

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

我不知道下一步该做什么。 我能找到的每个恢复指南都刚刚备份了 ibd* 文件和原理图目录，使用innodb_force_recovery = 6或innodb_force_recovery = 4启动服务器，一切都为他们工作了。

有人有想法吗？

提前致谢

Answer 1

尝试使用innodb_force_recovery = 1并导出转储。 表达式完成后，在/ var / lib / mysql中存储ib *文件的副本并除去它。 之后，您应该能够在没有innodb_force_recovery的情况下重新启动mariadb，并导入转储。

Answer 2

尝试从innodb_force_recovery = 1到innodb_force_recovery = 6交替运行mysql。 当mysql启动时，尝试mysqldump您的数据库并将其还原到测试节点上。 如果一切正常，请尝试在不使用innodb_force_recovery参数的生产节点上还原转储。

在还原备份/ var / lib / mysql目录之前。

Answer 3

我遇到了同样的问题。 检查您的系统日期和时区信息。 使用timedatectl命令。 我使用的服务器 ntp 默认处于活动状态 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的。 希望这可能会有所帮助。
