Jul 12, 2016 am 08:53 AMRecords of the entire process of building a WordPress blog from scratch on CentOS system, centoswordpress
Overview
I recently bought a server and am planning to set up a personal blog to continuously update my blog,
Environment
- Server operating system: CentOS 7.0
- Blog deployment server: Apache
- Backend language: PHP
- Database: MySql
- Front-end framework: WordPress
Steps
1. Install Apache
Installing Apache is very simple, just enter the following command in the terminal:
sudo yum install httpd
sudo means what to do with the root user, yum install means online installation; then enter yes to confirm the download and installation.
After the installation is complete, we need to start the service:
sudo service httpd start
After starting the server, don’t worry about it yet. You can directly enter the server’s IP address in the browser, and you should be able to see the Apache welcome page.
This page is used to test the operation of the Apache HTTP server after it has been installed………etc.
If your IP address has been bound to a domain name, you can also access it by entering your domain name in the browser. Isn’t it cool? It’s that simple. Let’s continue.
2. Install MySql
Install MySql and start MySql
sudo yum install mysql-server sudo service mysqld start
You can install and start mysql through the above command. When installing mysql, you will be asked for some simple configurations. Enter enter and yes and you will be fine.
3. Install PHP and related PHP components
Install PHP first
sudo yum install php php-mysql
Install PHP related components
yum install php-gd php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc
I installed these components first for future use. If you want to know all PHP components, you can use the following command to search:
yum search php-
4. Apache and Mysql services are started by default when booting
Use the following command to choose to start Apache and Mysql at boot:
sudo chkconfig http on sudo chkconfig mysql on
5. Test whether PHP is installed successfully
Create an info.php file:
sudo vim /var/www/html/info.php
Then enter i to enter edit mode and write the following PHP command in the file:
<?php phpinfo(); ?>
Then press the esc key to enter the command mode, press the Shift key and the z key twice to exit the saved file.
Enter the IP address/info.php in the browser, for example: 123.56.183.34/info.php and press Enter to see the PHP information.
6. Download WordPress
You can go to https://wordpress.org/ official website to browse, or download through the following command:
wget http://cn.wordpress.org/wordpress-3.9-zh_CN.zip
7. Decompression
Use unzip to unzip the file:
unzip wordpress-3.8-zh_CN.zip
8. Create a new database in Mysql
mysql -u root -p
Enter the database through the above command, and then enter the password: password
Then create a database called wordpress
create database wordpress;
9. Modify the wp-content.php file
Modify the wp-content.php file as follows,
/** MySQL數(shù)據(jù)庫(kù)名:wordpress */ define(‘DB_NAME', ‘wordpress'); /** MySQL數(shù)據(jù)庫(kù)用戶名 :root*/ define(‘DB_USER', ‘root'); /** MySQL數(shù)據(jù)庫(kù)密碼 :password*/ define(‘DB_PASSWORD', ‘password'); /** MySQL主機(jī)(不用修改) */ define(‘DB_HOST', ‘localhost');
10. Copy the file to the /var/www/html directory
cp -rf wordpress/* /var/www/html/
11. Test
Enter the server’s IP in the browser to view your homepage.

You can embed PHP code into HTML files, but make sure that the file has an extension of .php so that the server can parse it correctly. Use standard tags to wrap PHP code, insert dynamic content anywhere in HTML. In addition, you can switch PHP and HTML multiple times in the same file to realize dynamic functions such as conditional rendering. Be sure to pay attention to the server configuration and syntax correctness to avoid problems caused by short labels, quotation mark errors or omitted end labels.

The key to writing clean and easy-to-maintain PHP code lies in clear naming, following standards, reasonable structure, making good use of comments and testability. 1. Use clear variables, functions and class names, such as $userData and calculateTotalPrice(); 2. Follow the PSR-12 standard unified code style; 3. Split the code structure according to responsibilities, and organize it using MVC or Laravel-style catalogs; 4. Avoid noodles-style code and split the logic into small functions with a single responsibility; 5. Add comments at key points and write interface documents to clarify parameters, return values ??and exceptions; 6. Improve testability, adopt dependency injection, reduce global state and static methods. These practices improve code quality, collaboration efficiency and post-maintenance ease.
