MySQL - Centos7安装配置MariaDB10.3
生成配置
在 MariaDB Repository Configuration Tool 选择系统版本以及需要安装的mariadb版本。将生成的内容将生成的内容保存至/etc/yum.repos.d/mariadb.repo。
例如我选择的是系统版本是centos7 (x86_64)，要安装的是10.3[old stable]版本。
# MariaDB 10.3 CentOS repository list - created 2021-01-21 06:32 UTC
# http://downloads.mariadb.org/mariadb/repositories/
[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.3/centos7-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1
更换源
执行以下命令替换源地址
sudo sed -i 's#yum\.mariadb\.org#mirrors.ustc.edu.cn/mariadb/yum#' /etc/yum.repos.d/mariadb.repo
# 建议使用 HTTPS
sudo sed -i 's#http://mirrors\.ustc\.edu\.cn#https://mirrors.ustc.edu.cn#g' /etc/yum.repos.d/mariadb.repo
安装
sudo yum install MariaDB-server MariaDB-client
配置
- 启动服务并设为开机自启
systemctl start mariadb
systemctl enable mariadb
- 设置密码
执行mysql_secure_installation命令进行root密码的设置
mysql_secure_installation #设置root密码等相关
Enter current password for root (enter for none): # 输入数据库超级管理员root的密码(注意不是系统root的密码)，第一次进入还没有设置密码则直接回车
Set root password? [Y/n] # 设置密码，y
New password: # 新密码
Re-enter new password: # 再次输入密码
Remove anonymous users? [Y/n] # 移除匿名用户， y
Disallow root login remotely? [Y/n] # 拒绝root远程登录，n，不管y/n，都会拒绝root远程登录
Remove test database and access to it? [Y/n] # 删除test数据库，y：删除。n：不删除，数据库中会有一个test数据库，一般不需要
Reload privilege tables now? [Y/n] # 重新加载权限表，y。或者重启服务也许
- 设置字符集
在/etc/my.cnf文件[mysqld]标签下添加
init_connect='SET collation_connection = utf8_unicode_ci'
init_connect='SET NAMES utf8'
character-set-server=utf8
collation-server=utf8_unicode_ci
skip-character-set-client-handshake
在/etc/my.cnf.d/client.cnf文件[client]标签下添加
default-character-set=utf8
在/etc/my.cnf.d/mysql-clients.cnf文件[mysql]标签下添加
default-character-set=utf8
- 重启服务
systemctl restart mariadb
验证
- 查看
mariadb版本
[root@localhost ~]# mysql -uroot -p
