A summary of the entire process of building a PHP environment and WordPress blog program under CentOS, centoswordpress

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 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:

<&#63;php
phpinfo();
&#63;>

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
The official Chinese website is cn.wordpress.org
Download via 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数据库名：wordpress */
define(‘DB_NAME', ‘wordpress'); 
/** MySQL数据库用户名 :root*/
define(‘DB_USER', ‘root'); 
/** MySQL数据库密码 :password*/
define(‘DB_PASSWORD', ‘password');
/** MySQL主机（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.
