无法初始化 MySQL。“来自 pid 文件 /var/run/mariadb/mariadb.pid 的 mysqld_safe mysqld 结束”

Question

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：

错误说：

系统表空间必须可写

请检查MySQL数据目录的权限
