错误：软件包：akonadi-mysql-1.9.2-4.el7.x86_64 (@anaconda/7.0)
          需要：mariadb-server
          正在删除: 1:mariadb-server-5.5.35-3.el7.x86_64 (@anaconda/7.0)
              mariadb-server = 1:5.5.35-3.el7
          取代，由: mysql-community-server-5.7.22-1.el7.x86_64 (mysql57-community)
              未找到
 您可以尝试添加 --skip-broken 选项来解决该问题
 您可以尝试执行：rpm -Va --nofiles --nodigest

--解决：移除对 mariadb-libs的依赖

# yum -y remove mariadb-libs
# yum install mysql-community-server
