我无法在Linux上启动MySQL – 错误mysqld_safe

我在networking上的许多论坛中发现,但我没有find我的解决scheme。 当我在linux ubuntu server 12.04中启动服务mysql时,出现这个错误:

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 

我已经给文件夹mysql的权限,我也试着为根mysql创build一个新的密码。 但到目前为止没有任何工作。

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, eg 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, eg start mysql start: Job failed to start

MySQL正在使用它自己的用户,所以在root下启动它并不是一个明智的决定。 而现在,当你已经尝试过,你的一些文件可以被root所有,所以服务将无法启动。

  • 检查MySQL数据库的所有目录是否属于mysql用户。
  • 尝试通过新贵启动服务: start mysql
  • 在具有MySQL数据库的目录中检查日志文件。

端口3306已经在使用了吗? 尝试:

 netstat -an | grep 3306 

编辑:你如何启动MySQL? 尝试:

 /etc/init.d/mysql start
