无法启动mysql – mysql respawning太快,停了

今天我重新安装了ubuntu 12.04并开始设置我的本地开发环境.我安装了mysql并编辑了/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

syslog显示init脚本存在问题：

> tail -f /var/log/syslog

有任何想法吗？

我尝试过的事情：

我用Google搜索并发现apparmor(https://bugs.launchpad.net/ubuntu/+source/mysql-5.5/+bug/970366)的Ubuntu错误,我将apparmor从强制模式更改为抱怨模式：

sudo apt-get install apparmor-utils
sudo aa-complain /usr/sbin/mysqld
sudo /etc/init.d/apparmor reload

但它没有帮助.我还是无法启动mysql.

我还认为问题可能是因为InnoDB日志文件的大小与mysql所期望的大小不同.我在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,确保不要以任何方式触及/etc/mysql/my.cnf. Mysql正在工作,所以我可以继续我需要做的事情.但是我需要在某个时候编辑它 – 希望我已经找到了解决方案,或者这个问题已经得到了回答……

解决方法:

我终于找到了问题.基本上,某些参数的定义已从先前版本的mysql中删除,并已被替换为不同的名称.要修复,请在/etc/mysql/my.cnf中替换：

# Tom Added to ensure the server character set is set to utf8
default-character-set = utf8
default-collation     = utf8_general_ci

有：

# Tom Added to ensure the server character set is set to utf8
character_set_server  = utf8
collation_server      = utf8_general_ci

这是关联的启动板错误报告：https://bugs.launchpad.net/ubuntu/+source/mysql-5.5/+bug/958120.

或轻松运行：

# Miraz added dpkg-reconfigure
dpkg-reconfigure mysql-server-5.5

但请确保没有安装旧的mysql版本安装,如果有,请删除：

# Miraz quick mysql package check
dpkg -l *mysql*
