1.安装nodejs

# 更新下
dnf update -y
# 查看可用版本
sudo dnf module list nodejs
# 安装
sudo dnf module install nodejs:20

2.安装mariadb

2.1 安装、启动、开机启动

# 安装
dnf install mariadb-server
# 启动
systemctl start mariadb
# 开启启动项
systemctl enable mariadb

2.2首次配置

# 首次配置
mysql_secure_installation

会提示：

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we'll need the current password for the root user. If you've just installed MariaDB, and haven't set the root password yet, you should just press enter here.

Enter current password for root (enter for none): OK, successfully used password, moving on...

Setting the root password or using the unix_socket ensures that nobody can log into the MariaDB root user without the proper authorisation.

You already have your root account protected, so you can safely answer 'n'.

Switch to unix_socket authentication [Y/n] n

上面是问：要不要使用unix_socket认证方式，选否

... skipping.

You already have your root account protected, so you can safely answer 'n'.

Change the root password? [Y/n] y

上面是问：是否要重置密码：可以选是，然后输入新密码

New password: Re-enter new password: Password updated successfully! Reloading privilege tables.. ... Success!

By default, a MariaDB installation has an anonymous user, allowing anyone to log into MariaDB without having to have a user account created for them. This is intended only for testing, and to make the installation go a bit smoother. You should remove them before moving into a production environment.

Remove anonymous users? [Y/n] y

上面是问：是否删除匿名账户

... Success!

Normally, root should only be allowed to connect from 'localhost'. This ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] n

上面是问：是否禁止root远程登录

... skipping.

By default, MariaDB comes with a database named 'test' that anyone can access. This is also intended only for testing, and should be removed before moving into a production environment.

Remove test database and access to it? [Y/n] y

上面是问：是否删除test数据库

• Dropping test database... ... Success!
• Removing privileges on test database... ... Success!

Reloading the privilege tables will ensure that all changes made so far will take effect immediately.

Reload privilege tables now? [Y/n] y ... Success!

上面是问：是否刷新权限

2.2 开启远程连接

tips:默认不能直接修改mysql.user

# mkdir /etc/systemd/system/mariadb.service.d/
# cat > /etc/systemd/system/mariadb.service.d/datadir.conf <<EOF
[Service]
ReadWritePaths=/usr/local/mysql/data
EOF
# systemctl daemon-reload

然后在修改

mysql -uroot -p
#选择数据库
use mysql;
#修改权限（密码自定义）
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'Bsc123321' WITH GRANT OPTION;
# 刷新权限
flush privileges;
