MySQL（MariaDB）崩溃

早上好 - 我查看了之前关于在配置设置中将性能模式更改为“关闭”的帖子。看起来我们的配置已经设置为这样了。所以不确定是什么导致了崩溃问题。

[root@#### etc]# vim my.cnf

[mysqld]

general_log             = 1

general_log_file=/var/log/mariadb/query.log



datadir=/var/lib/mysql

socket=/var/lib/mysql/mysql.sock



symbolic-links=0

innodb_file_per_table = 1

#thread_stack = 131072

# mgk change 11/23/15

thread_stack = 256k

net_buffer_length = 2K

read_rnd_buffer_size = 256K

read_buffer_size = 256K

sort_buffer_size = 64K

table_open_cache = 4

max_allowed_packet = 1M

key_buffer_size = 16K

performance_schema = off

以下是日志摘要

@michael-sqlbot 看起来像 Ubuntu 12.04 服务器-MySQL 不断崩溃-可能是 InnoDB 问题 - 代码日志涵盖了您的问题。
