准备数据库(MySQL),若已有MySQL,可忽略.

build MySQL table;

连接MySQL;

mysql -u root -p

创建数据表;

mysql> create database demo;

mysql> use demo;

mysql> create table pet(name varchar(30), owner varchar(30), species varchar(20), sex char(1));

添加数据表内容;

mysql> insert into pet values('brandon','Jack','puddle','m'),('dixie','Danny','chihuahua','f');

exit(); ----退出MySQL

backup MySQL;

前情提示,启用二进制;

备份数据表;备份my.cnf;

$ mysqldump --all-databases --user=root --password --master-data > backupdb.sql

$ sudo cp /etc/mysql/my.cnf /opt/my.cnf.bak

del MySQL;

停止MySQL服务;

$ sudo service mysql stop //RHEL6

$ sudo systemctl stop mysql //RHEL7

$ sudo /etc/init.d/mysql stop //RHEL6

移除MySQL配置及文件;

$ sudo yum remove mysql* mysql-server mysql-devel mysql-libs

$ sudo rm -rf /var/lib/mysql

build mariadb;

安装 mariadb;以及相关依赖包;

$ sudo vi /etc/yum.repos.d/MariaDB.repo //创建自定义的yum源

....................................... //以下为文件内容

name = MariaDB

baseurl = http://yum.mariadb.org/5.5/centos7-amd64

gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB

gpgcheck=1

MySQL ==>> MARIADB;

将数据表导入到mariadb中;
