CentOS下php使用127.0.0.1不能连接mysql的解决方法

Jun 07, 2016 pm 04:28 PM
centos php cannot use connect

php代码很简单: $server="127.0.0.1"; println("Begin"); $link = mysql_connect($server,"mysql","mysql"); if (!$link) { die('Could not connect: ' . mysql_error().mysql_errno()); } linux本机下使用php mysql.php 可以查看运行结果,但是 在我的wind

php代码很简单:


$server="127.0.0.1";
println("Begin");
$link = mysql_connect($server,"mysql","mysql");
if (!$link) {
    die('Could not connect: ' . mysql_error().mysql_errno());
}

linux本机下使用php mysql.php 可以查看运行结果,但是 在我的windows浏览器下报错:


Could not connect: Can't connect to MySQL server on '127.0.0.1' (13) 2003

原因:


#getsebool -a | grep httpd
[neo@neo phpMyTest]$ getsebool -a | grep httpd


发现 httpd_can_network_connect --> off
解决方案:


#setsebool httpd_can_network_connect 1

原来是 SELINUX,所以我一般直接关闭SELINUX和 iptables ip6tables


# 关闭SELINUX
chkconfig --level 12345 iptables off

chkconfig --level 12345 ip6tables off

service iptables stop

service ip6tables stop


查看SELinux状态:

1、/usr/sbin/sestatus -v      ##如果SELinux status参数为enabled即为开启状态

SELinux status:                 enabled

2、getenforce                 ##也可以用这个命令检查

关闭SELinux:

1、临时关闭(不用重启机器):

setenforce 0                  ##设置SELinux 成为permissive模式

                              ##setenforce 1 设置SELinux 成为enforcing模式

2、修改配置文件需要重启机器:

修改/etc/selinux/config 文件

将SELINUX=enforcing改为SELINUX=disabled

How to optimize CentOS HDFS configuration How to optimize CentOS HDFS configuration Apr 14, 2025 pm 07:15 PM

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

PHP: Handling Databases and Server-Side Logic PHP: Handling Databases and Server-Side Logic Apr 15, 2025 am 12:15 AM

PHP uses MySQLi and PDO extensions to interact in database operations and server-side logic processing, and processes server-side logic through functions such as session management. 1) Use MySQLi or PDO to connect to the database and execute SQL queries. 2) Handle HTTP requests and user status through session management and other functions. 3) Use transactions to ensure the atomicity of database operations. 4) Prevent SQL injection, use exception handling and closing connections for debugging. 5) Optimize performance through indexing and cache, write highly readable code and perform error handling.

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
