我尝试构建包含数据库，表和简单值的MariaDB docker镜像。但它失败了，而且，我找不到任何日志。这是我的Dockerfile：
FROM centos:centos7
RUN yum install -y mariadb-server mariadb
RUN mysql_install_db --user=mysql --ldata=/var/lib/mysql/
ADD my.cnf /etc/
RUN sed -i '/[mysqld]/aport=3306' /etc/my.cnf
RUN \
echo "/usr/bin/mysqld_safe --basedir=/usr &" > /tmp/config && \
echo "cat /var/log/mariadb/mariadb.log" >> /tmp/config && \
echo "mysqladmin -u mysql password 11111" >> /tmp/config && \
echo "mysql -u mysql -p -h localhost test" >> /tmp/config && \
bash /tmp/config && \
rm -f /tmp/config
RUN \
echo "use test" > /tmp/config1 && \
echo "mysql -e 'GRANT ALL PRIVILEGES ON . TO mysql@localhost IDENTIFIED BY 1111' " >> /tmp/config1 && \
echo "FLUSH PRIVILEGES;" >> /tmp/config1 && \
bash /tmp/config1 && \
rm -f /tmp/config1
VOLUME ["/var/lib/mysql"]
WORKDIR /data
EXPOSE 3306
CMD ["/usr/bin/mysqld_safe"]
但是docker会抛出异常

我该如何解决这个问题？
