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

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

Confirm the target hard disk device name (such as /dev/sda) to avoid accidentally deleting the system disk; 2. Use sudoddif=/dev/zeroof=/dev/sdXbs=1Mstatus=progress to overwrite the zero value in full disk, which is suitable for most scenarios; 3. Use sudoshred-v-n3/dev/sdX for three random data overwrites to ensure that it cannot be restored; 4. Optionally execute sudobadblocks-wsv/dev/sdX for destructive write tests; finally use sudohexdump-C/dev/sdX|head to verify whether it is all zero and complete safe erasing.

To configure the PHP environment to support MongoDB, the core step is to install and enable the PHP driver of MongoDB to enable the PHP application to communicate with the MongoDB database. 1. Install MongoDBPHP driver, it is recommended to use PECL to install. If there is no PECL, you need to first install the PHP development package and related compilation tools; 2. Edit the php.ini file and add extension=mongodb.so (or .dll) to enable the extension; 3. Restart the web server or PHP-FPM service to make the configuration take effect; 4. Verify whether the extension is loaded successfully through phpinfo() or php-m. Frequently asked questions include missing PECL commands, compilation errors, php.ini

Make sure the system has loaded the bonding module and confirm that the network card interface is available, use modprobebonding and lsmod to verify; 2. Create /etc/sysconfig/network-scripts/ifcfg-bond0 configuration files, set DEVICE, TYPE, BONDING_MASTER, IP parameters and BONDING_OPTS=mode=active-backupmiimon=100primary=ens33; 3. Configure ifcfg files of physical network cards ens33 and ens34, set MASTER=bond0, SLAVE=yes and remove IP configuration
