This article mainly introduces how to make LAMP by Dockerfile. It is very detailed and has certain reference value. Friends who are interested must finish it.

Dockerfile makes LAMP (mysql default password is empty)

Environment:

Httpd 2.4.37

Mysql 5.6.40

Php 7.0.27

[root@oracle ~] # service docker start

Create docker Volum

[root@oracle ~] # docker volume create lamp_www

[root@oracle ~] # docker volume create lamp_apache_conf

[root@oracle ~] # docker volume create lamp_mysql_conf

[root@oracle ~] # docker volume create lamp_mysql_data

Create a / var/lib/docker/volumes directory on the host

[root@oracle ~] # mkdir / var/lib/docker/volumes (this path is docker by default and cannot be modified.)

[root@oracle ~] # mkdir / root/lamp

[root@oracle ~] # cd / root/lamp

[root@oracle my_mysql] # pwd

/ root/lamp

[root@oracle my_mysql] # vi Dockerfile

# download and decompress the source package. You can also download httpd-2.4.37.tar.gz to / root/lamp, and then directly use COPY httpd-2.4.37.tar.gz / usr/local/src (that is, transfer the httpd-2.4.37.tar.gz under the local directory directly to the / usr/local/src directory of image, and then execute WORKDIR / usr/local/src and RUN tar-zxvf httpd-2.4.37.tar.gz)

Note: RUN sed-I's impulse impulse replaceqqt with path to explain usr/local/apache2/bin/apxs to explain to USR to bind to usr/local/apache2/bin/apxs

(- I: directly modify the contents of the read file instead of outputting it to the terminal) (the content between # # can be modified directly)

(modify the first line of / usr/local/apache2/bin/apxs file #! / replace/with/path/to/perl/interpreter-w to #! / usr/bin/perl-w)

If you do not make the above changes, the following errors will occur:

Sorry, I cannot run apxs. Possible reasons follow:

Perl is not installed

Apxs was not found. Try to pass the path using-with-apxs2=/path/to/apxs

Apache was not built using-enable-so (the apxs usage page is displayed)

Create container

[root@oracle my_mysql] # docker run-itd-- privileged=true-p 80:80-p 3306 itd 3306-v lamp_www:/usr/local/apache2/htdocs-v lamp_apache_conf:/usr/local/apache2/conf-v lamp_mysql_conf:/etc/mysql-v lamp_mysql_data:/var/lib/mysql-- name lamp lamp / usr/sbin/init

[root@oracle my_mysql] # docker exec-I-t lamp bash

Change the configuration file of apache to parse the php file

[root@62b35d09adba htdocs] # vi / usr/local/apache2/conf/httpd.conf

Add the following at the end of the LoadModule

LoadModule php7_module modules/libphp7.so

(compiling uses-- with-apxs2=/usr/local/apache2/bin/apxs,httpd.conf to have this module)

# # usually it will be added automatically after the PHP is compiled and installed correctly. If not, it needs to be added manually.

Next, check the php dynamic link library file generated in the apache directory and find the existence of the libphp7.so file in the directory / usr/local/apache2/modules. What if it doesn't exist? Then php is not installed correctly.

Then add the following in

AddType application/x-httpd-php .php

Since the boot auto-startup apache is not successfully set in image, start apache manually here

/ usr/local/apache2/bin/httpd

[root@62b35d09adba htdocs] # vi / usr/local/apache2/htdocs/info.php

The test opens http://192.168.1.203/info.php and sees the following instructions for successfully configuring PHP

Create database data

Root@9a44df59980e:/# mysql-uroot-p

Mysql > show databases

Mysql > create database example default charset=utf8

Mysql > show create database example\ G

Mysql > use example

Mysql > create table tbl (idx integer (3), UserName varchar (30), LastName varchar (50), FreeText varchar (100) ENGINE=InnoDB AUTO_INCREMENT=1 default charset=utf8

Mysql > show create table tbl\ G

Mysql > show columns from tbl

Mysql > select from tbl

Mysql > insert into tbl values (1) just a test')

Mysql > update tbl set UserName='Berber' where UserName='Rafi'

Mysql > select from tbl

Mysql > delete from tbl where idx=1 limit 1

Mysql > insert into tbl values (1) just a test')

Mysql > select * from tbl

Mysql > quit

Bye

When the database is created and viewed on the host machine, you can see the database example created in the container above.

Create a PHP file (one of the biggest changes compared to PHP5,PHP7 is the removal of the mysql extension. It is recommended to use mysqli or pdo_mysql. In fact, starting with PHP5.5, PHP begins to prepare to abandon the mysql extension. If you use the mysql extension, you may have seen the prompt "Deprecated: mysql_connect (): The mysql extension is deprecated and will be removed in the future: use mysqli or PDO instead in". So in future programs, in order to maintain compatibility, we should minimize the use of mysql extensions for database connections.)

(the following example uses mysqli_query instead of mysql_connect)

[root@2fec8154c8d0 php-7.0.27] # vi / usr/local/apache2/htdocs/index.php

Test LAMP to open http://192.168.1.203/index.php, and you can already see the data

# Note: the speed of pushing Docker Hub is very slow. Wait patiently and it is likely to fail. If you fail, you will try to retransmit it many times.
