1. Download php-apache image

Do the following in the web server:

Docker pull php:7.2-apache

When the download is complete, use the docker images command to check the image in

2. Create scripts to generate mysql and httpd-php containers

In web:

Vim docker_web.sh

#! / bin/bash

Docker run-- name httpd-php-p 80:80\-v / data/docker/httpd/conf:/etc/apache2/sites-enabled\-v / data/docker/www:/var/www/html\-v / data/docker/httpd/logs:/var/log/apache2\-d php:7.2-apache

In mysql:

Vim docker_mysql.sh

#! / bin/bash

Docker run-- name mysql-p 3306 data/docker/mysql/data:/var/lib/mysql 3306\-v / data/docker/mysql/data:/var/lib/mysql\-v / data/docker/mysql/conf:/etc/mysql/conf.d\-v / data/docker/mysql/logs:/logs\

-e MYSQL_ROOT_PASSWORD=test123456\ # set the root password for mysql

-d mysql:latest-- character-set-server=utf8 # uses utf8 encoding

# Note that there are comments in the script that may cause an error docker: invalid reference format###

3. Start the mysql and httpd-php containers

In web:

Sh docker_web.sh

In mysql:

Sh docker_mysql.sh

4. Test the web server

Enter on the command line

Echo "" > / data/docker/www/index.php

Open a browser to access the ip address of the web server

5. Modify the password encryption method of mysql

Change the password encryption mode of mysql to mysql_native_password

Vim / data/docker/mysql/conf/docker_mysql.cnf

[mysqld] default-authentication-plugin=mysql_native_password

If the encryption method is not modified, the lower version of mysql client will report an error when logging in.

6. Database operation

Log in to the mysql container to create and configure wordpress database

Docker exec-it mysql / bin/bash mysql-uroot-ptest123456

Mysql > create database wordpress

Mysql > create user wps@localhost identified by '123456'

Mysql > grant all privileges on wordpress. To wps@localhost

Mysql > create user wps@192.168.8.126 identified by '123456'

Mysql > grant all privileges on wordpress. To wps@192.168.8.126

Mysql > alter user wps@192.168.8.126 identified with mysql_native_password by '123456'

Mysql > create user wps@192.168.8.127 identified by '123456'

Mysql > grant all privileges on wordpress.* to wps@192.168.8.127

Mysql > alter user wps@192.168.8.127 identified with mysql_native_password

By '123456'

Mysql > exit

7. Connection testing

In web1 and web2:

The mysql_connect () function is not recommended by PHP5.0 at the beginning, but it is discarded directly when it comes to php7.0, and the alternative function is mysqli_connect ().

Go to the mysql container and install the mysqli extension

Docker exec-it httpd-php / bin/bash

Apt-get update

Apt-get install libpng-dev

Cd / usr/local/bin/

. / docker-php-ext-install gd mysqli

. / docker-php-ext-enable gd mysqli

Exit

Docker restart httpd-php

Write a test php that connects to mysql

Vim / data/docker/www/con.php

Open a browser and enter 192.168.8.126/con.php

8. Download the wordpress blog system and configure

Wget https://cn.wordpress.org/wordpress-4.9.4-zh_CN.tar.gz

Tar-zxvf wordpress-4.9.4-zh_CN.tar.gz-C / data/docker/www/

Browsers access http://192.168.8.126/wordpress

As shown in the figure, note that the host writes ip to the virtual machine with mysql service installed.
