First of all, you need to have the required tar packages in the environment, and you can use [docker pull] () to download these images.

Now we are using the downloaded image, so we need to import it.

[root@docker01] # docker load-I nginx.tar & & docker load-I wordpress.tar & & docker load-I mysql-5.7.tar & & docker load-I php.7.2-fpm.tar// Import nginx,wordpress,mysql,php Image

The whole process:

The client http requests the server port 80, which is mapped to port 80 of the Nginx container and entered into Nginx processing.

Nginx analysis request, if it is a static resource, read the content directly from the server; if it is a PHP script, call the server through the PHP container to get the script, and then FastCGI process it.

FastCGI parses the PHP script and accesses the MySQL container to read and write data if necessary.

[Mysql:172.16.10.20] ()

[Php: 172.16.10.30] ()

Home directory for website access: / wwwroot

Configuration file for Nginx: / docker

/ etc/nginx/conf.d # nginx configuration file

[root@docker01 ~] # docker run-itd-- name test nginx:latest / / start a nginx first, which is used to copy configuration files and access the home directory [root@docker01 ~] # mkdir-p / wwwroot / docker// to create a mount directory [root@docker01 ~] # docker cp test:/etc/nginx / docker/// copy configuration files to the mount directory [root@docker01 ~] # ls / docker/nginx

[root@docker01 ~] # docker cp test:/usr/share/nginx/html / wwwroot/// copy access directory to mount directory [root@docker01 ~] # ls / wwwroot/html1) create a custom network [root@docker01 ~] # docker network create-d bridge-- subnet 172.16.10.0 lnmp2 24-- gateway 172.16.10.1 lnmp2) run the nginx container [root@docker01 ~] # netstat-anpt | grep 80 / View port 80 is Not occupied [root@docker01] # docker run-itd-- name nginx-v / docker/nginx:/etc/nginx-v / wwwroot/html:/usr/share/nginx/html-p 80:80-- network lnmp-- ip 172.16.10.10 nginx// running a nginx service And specify ip, map port, mount directory [root@docker01 ~] # docker ps// to check whether the container exists.

-e: set environment variables

[root@docker02 ~] # docker ps

Install mysql and set the password

[root@docker01 html] # yum-y install mysql// install MySQL [root @ docker01 ~] # mysql-u root-p123.com-h 127.0.0.1-P 3306

Randomly create a new library for verification:

MySQL [(none)] > create database name

Then check to see if there is a library you just created:

MySQL [(none)] > show databases

4) run the php container and create the php page [root@docker01 html] # docker run-itd-- name phpfpm-p 9000 docker run 9000-v / wwwroot/html:/usr/share/nginx/html-- network lnmp-- ip 172.16.10.30 php:7.2-fpm [root@docker01 ~] # cd / wwwroot/html [root@docker01 wwwroot] # vim test.php// add php test interface [root@docker02 ~] # docker ps

5) modify the nginx configuration file, and connect nginx and php to [root@docker01 html] # cd / docker/nginx/conf.d/ [root@docker01 conf.d] # vim default.conf location / {root / usr/share/nginx/html; index index.html index.htm index.php; # 10 to add index.php}

Location ~\ .php$ {root / usr/share/nginx/html; fastcgi_pass 172.16.10.30 root 9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params;}

Restart nginx after setting up

[root@docker01 conf.d] # docker restart nginx// restart nginx [root@docker01 conf.d] # docker ps

Browser test access to nginx and php

The description is the connection between nginx and php, no problem, and then the connection between php and MySQL. Here we use a phpmyadmin database management tool

6) modify nginx configuration file, php and mysql connection [root@docker01 html] # cd / wwwroot/html

Upload phpMyAdmin package. If not, please download it at https://github.com/phpmyadmin/phpmyadmin/releases.

[root@docker01 html] # unzip phpMyAdmin-4.9.1-all-languages.zip / / extract phpmyadmin package [root@docker01 html] # mv phpMyAdmin-4.9.1-all-languages phpmyadmin// change the name of the file you just extracted [root@docker01 html] # cd / docker/nginx/conf.d/ [root@docker01 conf.d] # vim default.conf / / modify the nginx configuration file location / phpmyadmin {root / usr/share/nginx/html Index index.html index.htm index.php;}

Location ~ / phpmyadmin/ (? (. *)\. (php | php5)? $) {root / usr/share/nginx/html; fastcgi_pass 172.16.10.30 root 9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params;}

[root@docker01 conf.d] # docker restart nginx [root@docker01 conf.d] # docker ps

Browsers access http://192.168.1.11/phpmyadmin/index.php

The red box is a normal phenomenon, don't panic, and then solve it.

We need to make changes to the php image and add php and MySQL connection modules

Write a Dockerfile

[root@docker01 conf.d] # cd [root@docker01 ~] # vim DockerfileFROM php:7.2-fpmRUN apt-get update & & apt-get install-y\ libfreetype6-dev\ libjpeg62-turbo-dev\ libpng-dev\ & & docker-php-ext-install-j$ (nproc) iconv\ & & docker-php-ext-configure gd-- with-freetype-dir=/usr/include/-- with-jpeg-dir=/usr/include/ \ & & docker-php-ext-install-j$ (nproc) gd\ & & docker-php-ext-install mysqli pdo pdo_mysql

Create php image based on dockerfile

[root@docker01 ~] # docker build-t phpmysql. / / create an image based on Dockerfiler

Delete the previous php container

[root@docker01 ~] # docker stop phpfpm [root@docker01 ~] # docker rm phpfpm / / close and delete the php container

Run the container with the new php image

[root@docker01] # docker run-itd-- name phpfpm-p 9000 itd 9000-v / wwwroot/html:/usr/share/nginx/html-- network lnmp-- ip 172.16.10.30 phpmysql// re-run with the newly made php image

/ / modify the configuration file of phpmyadmin, specify the IP of the connected database, and then restart the php container

[root@docker01 html] # cd / wwwroot/html/phpmyadmin/ [root@docker01 phpmyadmin] # cp config.sample.inc.php config.inc.php [root@docker01 phpmyadmin] # vim config.inc.php$cfg ['Servers'] [$] [' auth_type'] = 'cookie';/* Server parameters * / $cfg [' Servers'] [$] ['host'] =' 172.16.10.20]; # 31 write the IP address of the mysql database $cfg ['Servers'] [$I] [' compress'] = false $cfg ['Servers'] [$I] [' AllowNoPassword'] = false

[root@docker01 phpmyadmin] # docker restart phpfpm / / restart the phpfpm container

Browser test access to http://192.168.1.11/phpmyadmin/index.php

User name: root password: 123.com

After logging in successfully, you can see the database created by mysql before.
