我无法在Linux上启动MySQL – 错误mysqld_safe

前端之家收集整理的这篇文章主要介绍了我无法在Linux上启动MySQL – 错误mysqld_safe前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
我在网络上的许多论坛中找到了,但我找不到我的解决方案.
当我在 linux ubuntu server 12.04中启动服务 mysql时,我收到此错误
root@stroke:/# MysqLd_safe &
[1] 5789
root@stroke:/# 131001 10:12:29 MysqLd_safe Logging to syslog.
131001 10:12:29 MysqLd_safe Starting MysqLd daemon with databases from /var/lib/MysqL
131001 10:12:29 MysqLd_safe MysqLd from pid file /var/run/MysqLd/MysqLd.pid ended

我已经给了MysqL文件夹的权限,我也尝试为root MysqL创建一个新密码.但到目前为止还没有任何效果.

感谢帮助.

一些信息:

root@stroke:/# /etc/init.d/MysqL start
Rather than invoking init scripts through /etc/init.d,use the service(8)
utility,e.g. service MysqL start

Since the script you are attempting to invoke has been converted to an
Upstart job,you may also use the start(8) utility,e.g. start MysqL
start: Job Failed to start

解决方法

MysqL正在它自己的用户下工作,所以在root下启动它并不是一个明智的决定.现在,当您已经尝试过某些文件可以由root拥有时,服务将无法启动.

>检查MysqL数据库的所有目录是否由MysqL用户拥有.>尝试通过upstart启动服务:启动MysqL>在具有MysqL数据库的目录中检查日志文件.
