数据库的安装方式：
1、RPM包
2、源码包
3、通用二进制格式的程序包
详细解析源码包升级：这里以mariadb-5.5.46-linux-x86_64.tar.gz为例
[root@centos7 ~]# rpm -q mariadb-server
mariadb-server-5.5.44-2.el7.centos.x86_64
[root@centos7 ~]# tar xf mariadb-5.5.46-linux-x86_64.tar.gz -C /usr/local/ ——/usr/local：源码包安装路径
[root@centos7 ~]# cd /usr/local/
[root@centos7 local]# ln -sv mariadb-5.5.46-linux-x86_64 MySQL ‘mysql’ -> ‘mariadb-5.5.46-linux-x86_64’
[root@centos7 local]# ll mysql/
