1、CentOS 7.6最小化方式安装系统后,其yum默认base源中的mariadb-server版本为5.5.60,且没有mariadb-client软件包

2、配置下载MariaDByum源:

# vim /etc/yum.repos.d/MariaDB.repo

[mariadb]

name=MariaDB Repo

baseurl=http://mirrors.ustc.edu.cn/mariadb/yum/10.3/centos7-amd64/

gpgkey=http://mirrors.ustc.edu.cn/mariadb/yum/RPM-GPG-KEY-MariaDB

gpgcheck=1

enabled=1

# yum clean all

# yum makecache

3、在新配置的mariadb源中MariaDB-server的最新版本为10.3.14,且MariaDB-client的最新版本也为10.3.14

4、安装启动MariaDB-server

# yum -y install MariaDB-server

# systemctl start mariadb.service

# ss -tunlp | grep 3306

# systemctl enable mariadb.service

# systemctl status mariadb.service

# mysql_secure_installation

5、简单修改配置文件server.cnf

# vim /etc/my.cnf.d/server.cnf

[mysqld]

port=3306

socket=/var/lib/mysql/mysql.sock

datadir=/var/lib/mysql

log-error=/var/log/mariadb.log

lower_case_table_names=1

character-set-server=utf8mb4

collation-server=utf8mb4_unicode_ci

symbolic-links=0

备注:MariaDB Server 10.3.14的版本中默认主配置文件不再是/etc/my.cnf,而是my.cnf以及/etc/my.cnf.d/目录下的各类.cnf配置文件

# systemctl restart mariadb.service

6、授权远程用户登录:

# mysql -uroot -p

MariaDB> grant all on *.* to 'root'@'192.168.%.%' identified by '123456';

MariaDB> flush privileges;

7、 使用客户端工具Navicat远程连入MariaDB
