ubuntu 14.04 安装 MySQL 5.6 出错
 
 
二、可能出现的问题,如果安装过程中,终端出现如下提示:

          initctl:Unknown job:mysql

        则安装结束后,将无法启动 mysql。如下图所示:

    ubuntu 14.04 安装 mysql-server 及 可能出现的问题(Unknow job: mysql)和解决办法1

         出现这一问题,跟 mysql 没有直接关系, 而是由于初始守护进程控制工具(The init daemon control tool)没有使 mysql server daemon 从  /etc/init 启动。可以在终端键入如下命令手动恢复:

           (sudo) initctl reload-configuration  
root@xin-VirtualBox:/home/xin# apt-get install mysql-server-5.6
