What should I do if centos cannot find the php command?
Centos cannot find the php command: first execute "export PATH=$PATH:/usr/local/php/bin"; then execute "echo $PATH".

-bash: php: command not found Command not found
This problem is actually very simple. If you enter a command in the terminal and the system prompts If you say Command not found, it is either because you have not installed the corresponding software package, or because of a path setting problem. If it is because of a software package problem, there is nothing else to say, just install the corresponding software package. In another case, the user's path needs to be set.
-bash: ls: command not found 或者 -bash: ll: command not found
Cause: When setting environment variables, the editing profile file was not written correctly, resulting in commands such as ls not being recognized on the command line.
Solution:
export PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin bash: PHP: command not found
Solution:
export PATH=$PATH:/usr/local/php/bin
Then, echo $PATH and see, you will see it.
usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin:/usr/local/php/bin
At this time, you can directly type php -i in any directory of the system to execute it.
-bash:unzip: command not found
-bash: Two solutions to wget: command not found
Generally, when Linux is minimally installed, wget will not be installed by default.
Can be installed through the following two methods:
1. rpm installation
rpm download source address: http://mirrors.163.com/centos/6.2/ os/x86_64/Packages/
Download the RPM package of wget: http://mirrors.163.com/centos/6.2/os/x86_64/Packages/wget-1.12-1.4.el6.x86_64.rpm
rpm ivh wget-1.12-1.4.el6.x86_64.rpm Just install it.
2. yum installation
yum -y install wget
80 port prompt has been occupied
httpd not running, trying to start (98)Address already in use: AH00072: make_sock: could not bind to address [::]:80 (98)Address already in use: AH00072: make_sock: could not bind to address 0.0.0.0:80 no listening sockets available, shutting down AH00015: Unable to open logs
Solution:
# netstat -lnp|grep :80 tcp 0 0 :::80 :::* LISTEN 2184/httpd 杀掉服务 # killall -9 httpd 重启 # /etc/init.d/httpd start

Improve HDFS performance on CentOS: A comprehensive optimization guide to optimize HDFS (Hadoop distributed file system) on CentOS requires comprehensive consideration of hardware, system configuration and network settings. This article provides a series of optimization strategies to help you improve HDFS performance. 1. Hardware upgrade and selection resource expansion: Increase the CPU, memory and storage capacity of the server as much as possible. High-performance hardware: adopts high-performance network cards and switches to improve network throughput. 2. System configuration fine-tuning kernel parameter adjustment: Modify /etc/sysctl.conf file to optimize kernel parameters such as TCP connection number, file handle number and memory management. For example, adjust TCP connection status and buffer size

When configuring Hadoop Distributed File System (HDFS) on CentOS, the following key configuration files need to be modified: core-site.xml: fs.defaultFS: Specifies the default file system address of HDFS, such as hdfs://localhost:9000. hadoop.tmp.dir: Specifies the storage directory for Hadoop temporary files. hadoop.proxyuser.root.hosts and hadoop.proxyuser.ro

CentOS Platform Hadoop Distributed File System (HDFS) Performance Optimization Guide Optimizing HDFS Performance is a multi-faceted issue, and multiple parameters need to be adjusted for specific situations. The following are some key optimization strategies: 1. Memory management adjusts the NameNode and DataNode memory configuration: reasonably configure the HADOOP_NAMENODE_OPTS and HADOOP_DATANODE_OPTS environment variables according to the actual memory size of the server to optimize memory utilization. Enable large page memory: For high memory consumption applications (such as HDFS), enabling large page memory can reduce memory page allocation and management overhead and improve efficiency. 2. Disk I/O optimization uses high-speed storage

The CentOS shutdown command is shutdown, and the syntax is shutdown [Options] Time [Information].

Enable PyTorch GPU acceleration on CentOS system requires the installation of CUDA, cuDNN and GPU versions of PyTorch. The following steps will guide you through the process: CUDA and cuDNN installation determine CUDA version compatibility: Use the nvidia-smi command to view the CUDA version supported by your NVIDIA graphics card. For example, your MX450 graphics card may support CUDA11.1 or higher. Download and install CUDAToolkit: Visit the official website of NVIDIACUDAToolkit and download and install the corresponding version according to the highest CUDA version supported by your graphics card. Install cuDNN library:

The key differences between CentOS and Ubuntu are: origin (CentOS originates from Red Hat, for enterprises; Ubuntu originates from Debian, for individuals), package management (CentOS uses yum, focusing on stability; Ubuntu uses apt, for high update frequency), support cycle (CentOS provides 10 years of support, Ubuntu provides 5 years of LTS support), community support (CentOS focuses on stability, Ubuntu provides a wide range of tutorials and documents), uses (CentOS is biased towards servers, Ubuntu is suitable for servers and desktops), other differences include installation simplicity (CentOS is thin)

CentOSStream8 system troubleshooting guide This article provides systematic steps to help you effectively troubleshoot CentOSStream8 system failures. Please try the following methods in order: 1. Network connection testing: Use the ping command to test network connectivity (for example: pinggoogle.com). Use the curl command to check the HTTP request response (for example: curlgoogle.com). Use the iplink command to view the status of the network interface and confirm whether the network interface is operating normally and is connected. 2. IP address and gateway configuration verification: Use ipaddr or ifconfi
