今天,我重新安装了ubuntu 12.04,然后开始设置本地开发环境。我安装了mysql并进行了编辑/etc/mysql/my.cnf
以优化InnoDB,但是当我尝试重新启动mysql时,它失败并出现错误:
[20:53][tom@Pochama:/var/www/website] (master) $ sudo service mysql restart
start: Job failed to start
系统日志显示初始化脚本存在问题:

有任何想法吗?
我已经尝试过的事情:
我用谷歌搜索发现了一个带有apparmor的Ubuntu bug(https://bugs.launchpad.net/ubuntu/+source/mysql-5.5/+bug/970366),我将apparmor从强制模式更改为投诉模式:
sudo apt-get install apparmor-utils
sudo aa-complain /usr/sbin/mysqld
sudo /etc/init.d/apparmor reload
但这没有帮助。我仍然无法启动mysql。
我也认为问题可能是因为InnoDB日志文件的大小与mysql预期的大小不同。我在使用以下命令重新启动之前删除了innodb日志文件sudo mv /var/lib/mysql/ib_logfile* /tmp
。虽然没有运气。
解决方法:我重新安装了12.04,请确保不要以/etc/mysql/my.cnf
任何方式触摸。Mysql正在运行,因此我可以继续进行所需的工作。但是我需要在某个时候对其进行编辑-希望我能找到一个解决方案,否则该问题将在那时得到解答...
dpkg-reconfigure mysql-server-5.5
修复了我的配置中的任何错误。
