Question

我正在尝试在RedHat AWS框上启动干净的5.6 mysql安装。它在日志中打印以下内容后挂起。它最终死了：

mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql
[Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details).
[Warning] Buffered warning: Changed limits: max_open_files: 1024 (requested 5000)

[Note] Plugin 'FEDERATED' is disabled.
[Note] InnoDB: Using atomics to ref count buffer pool pages

[Note] InnoDB: Completed initialization of buffer pool
InnoDB: Error: pthread_create returned 13
mysqld_safe mysqld from pid file /var/run/mysqld/mysqld.pid ended

根本没有创建套接字。这是my.cnf：

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

# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0

# Recommended in standard MySQL setup
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

有什么想法吗？

Answer 1

$ perror 13
OS error code  13:  Permission denied

也许你在安装时根本没有？

[Warning] Buffered warning: Changed limits: max_open_files: 1024 (requested 5000)

这是由ulimit（在操作系统中）仅为1024引起的。

Answer 2

我也有InnoDB：错误：在Centos 7上启动mysql服务器时，pthread_create返回13。

发现这个问题，检查了mysql文件夹的权限，但找不到任何错误的权限。

将mysql服务器更新到最新版本为我修复了一切。（我现在在Ver 14.14 Distrib 5.6.23上）

尝试启动mysql时获取pthread_create错误13（权限）
