準備數據庫(MySQL),若已有MySQL,可忽略.
build MySQL table;
連接MySQL;
mysql -u root -p
創建數據表;
| mysql> create database demo;mysql> use demo;mysql> create table pet(name varchar(30), owner varchar(30), species varchar(20), sex char(1)); |
添加數據表內容;
mysql> insert into pet values('brandon','Jack','puddle','m'),('dixie','Danny','chihuahua','f');
exit(); ----退出MySQL
backup MySQL;
前情提示,啟用二進制;
備份數據表;備份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服務;
| $ 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;
安裝 mariadb;以及相關依賴包;
$ sudo vi /etc/yum.repos.d/MariaDB.repo //創建自定義的yum源
....................................... //以下為文件內容
| [mariadb]name = MariaDBbaseurl = http://yum.mariadb.org/5.5/centos7-amd64gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDBgpgcheck=1 |
.......................................
$ sudo yum install MariaDB-server MariaDB-client//安裝MariaDB
恢復my.cnf文件;
$ sudo cp /opt/my.cnf /etc/mysql/
啟動mariadb;
| $ sudo service mariadb start$ sudo systemctl start mariadb$ sudo /etc/init.d/mariadb start |
MySQL ==>> MARIADB;
將數據表導入到mariadb中;
$ mysql -u root -p < backupdb.sql
出現一下內容,表示登錄成功;恭喜你;
$ mysql -u root -p
......................................//以下為sql命令
| MariaDB [(none)]> show databases;MariaDB [(none)]> use test01;MariaDB [test01]> select * from pet; |
