LAMP is currently a more popular web framework, namely the website architecture scheme of Linux+Apache+Mysql+PHP. Docker is a very popular virtualized application container, which can create a lightweight and portable container for any application. Now we are going to deploy the LAMP environment through docker and build a wordpress blog system to test.
1. Download the mysql and php-apache images
docker pull mysql docker pull php:7.2-apache
Create a custom network lamp
docker network create lamp docker network ls
2. Create a script
vim docker_lamp.sh to generate mysql and httpd-php containers
#!/bin/bash
function mysql()
{
docker run -d -p 3306:3306 --name mysql -e MYSQL_ROOT_PASSWORD=root daocloud.io/library/mysql:5.7.5 \
-v /data/docker/mysql/data:/var/lib/mysql \
-v /data/docker/mysql/conf:/etc/mysql/conf.d -v /data/docker/mysql/logs:/logs
}
function httpd_php()
{
docker run --name httpd-php --net lamp -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
}
$1
3. Start mysql and httpd-php containers
sh docker_lamp.sh mysql sh docker_lamp.sh httpd_php
4. Write a php homepage file to test
echo "<?php phpinfo(); ?>" > /data/docker/www/index.php
Visit http://10.0.0.11 through a browser
5. Download the wordpress blog system
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/
6. Configure the wordpress blog
browser to visit http://10.0.0.11/wordpress
There is an error
7. Modify wp-config-sample.php configuration
cd /data/docker/www/wordpress/
vim wp-config-sample.php #Modify the following
/** The name of the WordPress database*/
define('DB_NAME', 'wordpress');
/** MySQL database user name*/
define('DB_USER', 'root');
/** MySQL database password*/
define('DB_PASSWORD', '123456');
/** MySQL host*/
define('DB_HOST', '10.0.0.11');
/** The default text encoding when creating a data table*/
define('DB_CHARSET', 'utf8');
/** Database collation type. Do not change if you are not sure*/
define('DB_COLLATE', '');
Use the browser to visit http://10.0.0.11/wordpress
After consulting the information, I found that the mysql_connect() function was not recommended since PHP5.0, but the function was directly abandoned in php7.0. The replacement function was mysqli_connect(). Finally, the cause of the problem was found.
8. Call to undefined function mysql_connect() problem solution
Enter into the mysql container to 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 php
vim /data/docker/www/test.php to test the connection to mysql
<?php
echo "Hello PHP<br/>";
$conn = mysqli_connect("10.0.0.11","root","123456");
if(!$conn){
echo "Failed to connect to the database";
}else{
echo "Connect to the database successfully";
}
phpinfo();
?>
Modify the wp-db.php file and replace mysql_connect with mysqli_connect
cd /data/docker/www/wordpress/ sed -i "s/mysql_connect/mysqli_connect/g" wp-includes/wp-db.php mv wp-config.php wp-config-sample.php
9. Reconfigure the wordpress blog
After filling in the configuration information for connecting to mysql according to the previous steps, you will see the following page, indicating that the mysql connection is successful.
You need to manually create the wp-config.php file and paste the above information into the wp-config.php file
vim /data/docker/www/wordpress/wp-config.php
Then click "install now", the following page appears
After entering the above information, click "Install WordPress"
