Beginner's Guide To The Complete Process Of Building A Rubik's Cube On A Us Server From Environment Preparation To Online Release

first, clarify the goal: if you want to build a rubik's cube cms or a self-developed "rubik's cube" project, first confirm the operating environment requirements (such as php version, database type, web server). common preparation lists include: purchasing or renting a us vps/cloud server, configuring public ip and domain name resolution, preparing operating system images (commonly used centos/ubuntu), and opening necessary ports (80/443/22).

it is recommended to use the latest lts version of the operating system, create a non-root administrative user, and configure ssh key login. example: create a user on ubuntu and disable password login: adduser deploy && usermod -ag sudo deploy , and set passwordauthentication no in /etc/ssh/sshd_config .

purchase a domain name and add an a record in dns management to point to the public ip of the us server. it is recommended to configure cdn acceleration and waf to improve access speed and security.

during the preparation stage, be sure to pay attention to the network latency, bandwidth, and availability of the us server to ensure smooth subsequent deployment.

rubik's cube applications usually require web services, php/runtime and databases. two common solutions: lamp (apache+mysql+php) or lemp (nginx+mariadb/mysql+php-fpm). consider performance and habits when choosing. the following uses lemp as an example to illustrate the basic steps.

commonly used commands on ubuntu: apt update && apt install nginx php-fpm php-mysql mariadb-server . after installation, start it and set it to start automatically at boot: systemctl enable --now nginx php7.x-fpm mariadb (replace 7.x according to the php version).

run mysql_secure_installation to complete the root password setting and security configuration, and create an independent database and user for mofang: create database mofang; create user 'mofanguser'@'localhost' identified by '强密码'; grant all on mofang.* to 'mofanguser'@'localhost';

adjust php-fpm's php.ini (such as upload_max_filesize, post_max_size, memory_limit) and nginx site configuration to enable php file processing and static resource caching.

deployment steps include code upload, dependency installation, database import and configuration file adjustment. it is recommended to use git+ci or direct sftp/rsync upload. if it is a php-based rubik's cube cms, you usually need to put the source code in the web root directory and configure the permissions.

place the code in /var/www/mofang and set the owner to www-data (nginx default user): chown -r www-data:www-data /var/www/mofang && find /var/www/mofang -type d -exec chmod 755 {} \\; && find /var/www/mofang -type f -exec chmod 644 {} \\; .

if the project provides a sql export file, use mysql -u mofanguser -p mofang < dump.sql to import the database; then modify the configuration file (such as config.php or .env) to fill in the database connection, site url, key, etc.

after deployment, visit the domain name test page and background login, check the logs (/var/log/nginx/error.log, php-fpm log) and adjust the environment or dependencies according to the errors.

basic security hardening and performance optimization must be done before going online. security aspects include ssh reinforcement, firewalls, web application protection, ssl deployment and file permission control; performance aspects include php-fpm pool adjustment, opcache, nginx cache, database indexing and cdn acceleration.

it is recommended to close unnecessary services, open only necessary ports, configure the firewall using ufw or firewalld, install fail2ban to prevent brute force logins, and force the use of https (let's encrypt free certificate).

enable php opcache and adjust opcache.memory_size according to memory; configure nginx's gzip, expires headers and static resource cache; establish necessary indexes for the database and enable slow_query_log to locate slow queries.

configure regular backups of databases and files (local + off-site), and test the recovery process to ensure quick rollback when problems occur.

after going online, server resources (cpu, memory, disk), service availability, access logs and security alarms need to be continuously monitored. you can use monitoring tools (such as prometheus+grafana, zabbix) or the cloud vendor's own monitoring service.

centrally collect nginx access and error logs and application logs, set key indicator thresholds (such as response time, error rate) and configure alarms (email/sms/dingtalk).

regularly update the system and components (apt/aptitude/yum), pay attention to performing upgrades during off-peak periods, and first verify the impact of large upgrades on rubik's cube applications in a test environment.

adopt horizontal expansion (load balancing) or vertical expansion (larger instances) based on traffic, and evaluate whether to use cdn and separated static storage (such as object storage) to reduce the pressure on the origin site.
