    这是一个创建于 3102 天前的主题,其中的信息可能已经有所发展或是发生改变。

    以前一直用 Debian 系,照着官方文档一路装过来都没啥问题,最近想换口味装了个 CentOS 7 ,结果一个 MySQL 就搞了一晚上没搞定。。

    大致过程,从官网下了个 Yum Repository

    # rpm -ivh mysql57-community-release-el7-8.noarch.rpm
    # yum update
    # yum install mysql-community-server
    

    一路顺利,然后启动

    # systemctl start mysqld
    Job for mysqld.service failed because the control process exited with error code. See "systemctl status mysqld.service" and "journalctl -xe" for details.
    

    报错,照着提示看了下发现并不能看懂。。对着一些信息搜索也无果,求教是什么原因

    # systemctl status mysqld.service
      mysqld.service - MySQL Server
       Loaded: loaded (/usr/lib/systemd/system/mysqld.service; enabled; vendor preset: disabled)

    mariadb 和 mysql 几乎完全兼容。

    @hbprotoss

    你这么说,反而不够严谨。你的这句话所表达的含义和你说“生产环境差不得”所想的含义其实是矛盾的。

    如果你非得说的话,应该说“有的生产环境可差不得这个‘几乎’”。


    其实绝大部分生产环境是可以无缝兼容的,可以很轻松的从 mysql 迁移到 mariadb ,但是有的生产环境确实不行。这也是我上面回复当中“几乎”的来源。


    另外,@Livid , hbprotoss 在 28 天前就回复我了,但是未读提醒在我发这个帖子的时候才出来。这是个 bug 还是啥?
