In Linux systems, 1. Use ipa or hostname-I command to view private IP; 2. Use curlifconfig.me or curlipinfo.io/ip to obtain public IP; 3. The desktop version can view private IP through system settings, and the browser can access specific websites to view public IP; 4. Common commands can be set as aliases for quick call. These methods are simple and practical, suitable for IP viewing needs in different scenarios.

As a pioneer in the digital world, Bitcoin’s unique code name and underlying technology have always been the focus of people’s attention. Its standard code is BTC, also known as XBT on certain platforms that meet international standards. From a technical point of view, Bitcoin is not a single code style, but a huge and sophisticated open source software project. Its core code is mainly written in C and incorporates cryptography, distributed systems and economics principles, so that anyone can view, review and contribute its code.

The shutdown command of Linux/macOS can be shut down, restarted, and timed operations through parameters. 1. Turn off the machine immediately and use sudoshutdownnow or -h/-P parameters; 2. Use the time or specific time point for the shutdown, cancel the use of -c; 3. Use the -r parameters to restart, support timed restart; 4. Pay attention to the need for sudo permissions, be cautious in remote operation, and avoid data loss.

To enable PHP containers to support automatic construction, the core lies in configuring the continuous integration (CI) process. 1. Use Dockerfile to define the PHP environment, including basic image, extension installation, dependency management and permission settings; 2. Configure CI/CD tools such as GitLabCI, and define the build, test and deployment stages through the .gitlab-ci.yml file to achieve automatic construction, testing and deployment; 3. Integrate test frameworks such as PHPUnit to ensure that tests are automatically run after code changes; 4. Use automated deployment strategies such as Kubernetes to define deployment configuration through the deployment.yaml file; 5. Optimize Dockerfile and adopt multi-stage construction

Slow transfer of Dogecoin can be solved by increasing the handling fee and avoiding peak hours. The main reasons include network congestion, too low handling fees and block capacity limitations; the recommended handling fees are adjusted between 1-10 DOGE/KB according to the network status; the methods to increase the speed are to increase the handling fees, avoid peaks, use light wallets, and query the status on the chain; the steps to set the handling fees are taken by Trust Wallet as an example, including entering the sending interface, clicking advanced settings, and setting the fees reasonably; Exchange transfers need to avoid maintenance periods and pay attention to the minimum amount and handling fees to ensure efficient confirmation and asset security.

Building an independent PHP task container environment can be implemented through Docker. The specific steps are as follows: 1. Install Docker and DockerCompose as the basis; 2. Create an independent directory to store Dockerfile and crontab files; 3. Write Dockerfile to define the PHPCLI environment and install cron and necessary extensions; 4. Write a crontab file to define timing tasks; 5. Write a docker-compose.yml mount script directory and configure environment variables; 6. Start the container and verify the log. Compared with performing timing tasks in web containers, independent containers have the advantages of resource isolation, pure environment, strong stability, and easy expansion. To ensure logging and error capture

In CentOS, the system log files are mainly stored in the /var/log directory. Common ones include: 1./var/log/messages record system messages; 2./var/log/secure record authentication-related logs; 3./var/log/dmesg record kernel information; 4./var/log/cron record timing task information; 5./var/log/boot.log record startup process. CentOS7 and above use rsyslog to manage logs, combined with systemd's journald tool, can be viewed through the journalctl command. It is also recommended to use logrotate to rotate logs and real
