centos中的nginx无法访问?我是不是漏了什么?
背景
- 我在
virtual box
下安装了一个最小化的centos 7
- 然后用的其他源
yum
安装的nginx
- 主机ip:
192.168.31.146
-
centos
桥接ip192.168.31.158
- 主机hosts添加地址:
192.168.31.158 cent.com
测试
-
nginx
已经启动,显示running -
nginx
配置文件default.conf
如下: -
nginx -t
显示正常 -
/usr/share/nginx/html
下默认有个html文件 - 主机
ping cent.com
可以ping通,ip是158 - nginx的log里都没有东西
问题
- 主机访问
http://cent.com
无法访问 - 为啥无法访问呢?我是不是漏掉了什么??
解决
- 确实是防火墙问题,感谢@_Zhao的回答,我把防火墙给忘了!
- centos7用的
firewalld
,我说iptables
怎么没开。。 - firewalld默认已经安装并启用了,如果需要nginx可以访问需要执行以下命令:
firewall-cmd --permanent --add-service=http
firewall-cmd --permanent --zone=trusted --add-port=80/tcp
- 其他命令可以参考firewalld使用简介

@savokiss
首先在centos
下尝试使用$curl http://127.0.0.1
命令访问nginx。
如果能够成功获取到nginx
的默认主页。
那么,问题基本出在防火墙上,centos 7
的防火墙使用firewalld
。
所以,你需要让firewalld
放行80
端口。
具体命令请自行google
。
但愿能解决你的问题。

PHP is used to build dynamic websites, and its core functions include: 1. Generate dynamic content and generate web pages in real time by connecting with the database; 2. Process user interaction and form submissions, verify inputs and respond to operations; 3. Manage sessions and user authentication to provide a personalized experience; 4. Optimize performance and follow best practices to improve website efficiency and security.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.

You can query the Docker container name by following the steps: List all containers (docker ps). Filter the container list (using the grep command). Gets the container name (located in the "NAMES" column).

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.

The core benefits of PHP include ease of learning, strong web development support, rich libraries and frameworks, high performance and scalability, cross-platform compatibility, and cost-effectiveness. 1) Easy to learn and use, suitable for beginners; 2) Good integration with web servers and supports multiple databases; 3) Have powerful frameworks such as Laravel; 4) High performance can be achieved through optimization; 5) Support multiple operating systems; 6) Open source to reduce development costs.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2.
