无法启动MYSQL服务器，它一直说“服务器退出而不更新PID文件”。我尝试重新创建PID文件，我在my.cmf文件中添加了PID文件的路径，但似乎没有任何帮助。我尝试重命名PID文件然后启动它似乎启动但它立即死亡。
这是mysql日志：

150724 15:27:28 mysqld_safe mysqld from pid file /var/run/mysqld/mysqld.pid ended
这是my.cmf文件中的内容。
[mysqld]
max_connections=500
slow_query_log=1
default-storage-engine=MyISAM
innodb_file_per_table=1
max_allowed_packet=268435456
open_files_limit=10000
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
任何想法可能有什么问题？
答案 0 :(得分：0)
尝试以下
1）确保MySQL具有PID文件的写权限
1）转到MySQL数据目录删除ibdata文件（别忘了带备份）
