装好系统 和相关服务httpd,mysql,php,一跑代码,发现php5.3中的spilt函数不能用,代码里面好多用的的啊,日
,赶紧上网找一下,有没有yum安装php5.2的要不改死代码了。
还真被我找到了。方法如下
1.环境
centos6.4 x86_64
2.添加源
wget -q -O - http://www.atomicorp.com/installers/atomic | sh
3.排除php5.3的包,我们只需要php5.2.17
vim /etc/yum.conf
exclude=*5.3.*
4.安装
yum install php php-mysql php-xml php-gd php-mbstring php-cli
大功告成,
ps:希望以后开发人员写代码别再用split()函数。

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

The CentOS shutdown command is shutdown, and the syntax is shutdown [Options] Time [Information]. Options include: -h Stop the system immediately; -P Turn off the power after shutdown; -r restart; -t Waiting time. Times can be specified as immediate (now), minutes ( minutes), or a specific time (hh:mm). Added information can be displayed in system messages.

Steps to configure IP address in CentOS: View the current network configuration: ip addr Edit the network configuration file: sudo vi /etc/sysconfig/network-scripts/ifcfg-eth0 Change IP address: Edit IPADDR= Line changes the subnet mask and gateway (optional): Edit NETMASK= and GATEWAY= Lines Restart the network service: sudo systemctl restart network verification IP address: ip addr

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)

CentOS installation steps: Download the ISO image and burn bootable media; boot and select the installation source; select the language and keyboard layout; configure the network; partition the hard disk; set the system clock; create the root user; select the software package; start the installation; restart and boot from the hard disk after the installation is completed.

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

Backup and Recovery Policy of GitLab under CentOS System In order to ensure data security and recoverability, GitLab on CentOS provides a variety of backup methods.
