mysql 服务在启动时超时

Question

启动 mysql 超时。我不知道为什么。

我按照建议查看了日志文件，只是得知它正在超时，但不明白为什么。我什至尝试重新安装 lamp 堆栈，但这是相同的结果。

toor@linux:~$ sudo /etc/init.d/mysql start
[....] Starting mysql (via systemctl): mysql.service
Job for mariadb.service failed because a timeout was exceeded.
See "systemctl status mariadb.service" and "journalctl -xe" for details.
failed!


toor@linux:~$ systemctl status mariadb.service

我尝试粘贴 journalctl -xe 的结果，但无法提交，因为其中有相当多的代码。所以这里是 output.

sudo aa-status 向您展示 apparmor 正在做什么。

sudo apt-get install apparmor-utils 添加了一些命令，使 apparmor 配置文件更容易。

sudo aa-complain /usr/sbin/mysqld 将个人资料从 "enforce" 转为抱怨。

sudo service apparmor reload 重启 apparmor，瞧... sudo /etc/init.d/mysql start重新启动服务器。
