安装并初始化mariadb v10数据库

本文意在指导使用YUM来安装最新版mariadb

Step 1:

新建repo文件

touch /etc/yum.repos.d/MariaDB.repo

官方源

[mariadb]
name = MariaDB-10.3.9
baseurl=http://yum.mariadb.org/10.3.9/centos7-amd64
# alternative: baseurl=http://archive.mariadb.org/mariadb-10.3.9/yum/centos7-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

中科大源

[mariadb]
name = MariaDB
baseurl = https://mirrors.ustc.edu.cn/mariadb/yum/10.1/centos7-amd64/
gpgkey=https://mirrors.ustc.edu.cn/mariadb/yum/RPM-GPG-KEY-MariaDB
gpgcheck=1

导入GPG

rpm --import https://yum.mariadb.org/RPM-GPG-KEY-MariaDB

Step 2:

安装Mariadb数据库

[root@YunDisk Exdisk]# yum install mariadb mariadb-server

Step 3:

设置MariaDB

• 启动MariaDB

  [root@YunDisk Exdisk]# systemctl start mariadb

• 停止MariaDB

  [root@YunDisk Exdisk]# systemctl stop mariadb

• 设置开机启动

  [root@YunDisk Exdisk]# systemctl enable mariadb

• 拷贝配置文件

  [root@YunDisk Exdisk]# cp /usr/share/mysql/my-huge.cnf /etc/my.cnf

Step 4:

修改数据库为UTF8（支持中文）

[root@YunDisk Exdisk]# vim /etc/my.cnf

[client]
default-character-set=utf8
[mysqld]
default-storage-engine=INNODB
character-set-server=utf8
collation-server=utf8_general_ci

Step 5:

再次启动MariaDB

[root@YunDisk Exdisk]# systemctl start mariadb

Step 6:

设置密码

[root@YunDisk Seafile]# mysql -uroot -p

MariaDB [(none)]> use mysql;
MariaDB [mysql]> update user set password=PASSWORD('123456') where user="root";
MariaDB [mysql]> flush privileges;
MariaDB [mysql]> quit
