我正在 Fedora 22 上全新安装 MySQL。运行 mysql_install_db 后，我尝试使用 mysqld_safe 启动守护进程，但它不起作用。系统说：
mysqld_safe Logging to '/var/log/mariadb/mariadb.log'.
mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql
mysqld_safe mysqld from pid file /var/run/mariadb/mariadb.pid ended
我该如何让它发挥作用？
以下是 mariadb.log 内容：
mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql
[Note] /usr/libexec/mysqld (mysqld 10.0.23-MariaDB) starting as process 20443 ...
[Note] InnoDB: Using mutexes to ref count buffer pool pages
[Note] InnoDB: The InnoDB memory heap is disabled
[Note] InnoDB: Mutexes and rw_locks use GCC atomic builtins
[Note] InnoDB: Memory barrier …mysqld套接字的版本与mysqld服务器的版本不同是不是有问题？我在启动期间在 mysqld 日志中注意到了这一点

然而，当我显示变量时我得到了这个
显示类似“%version%”的变量；
