This article shares the entire process of using docker to build the operating environment of php7 and nginx. It is shared for your reference and learning. Let’s take a look at the detailed introduction below:
Environment introduction
Root directory: /docker
Website root directory: /docker/www
nginx related directory: /docker/nginx/
Preparation
1. Use docker accelerator
curl -sSL /daotools/set_mirror.sh | sh -s service docker restart
2. Download related images
docker pull nginx docker pull php:7.1.0-fpm
3. Create relevant directories
mkdir -p /docker/www mkdir -p /docker/nginx/
4. Edit
vim /docker/nginx//
# The following is the example contentserver {
listen 80 default_server;
server_name _;
root /usr/share/nginx/html;
location / {
index ;
autoindex off;
}
location ~ \.php(.*)$ {
root /var/www/html/;
fastcgi_pass 172.17.0.2:9000;
fastcgi_index ;
fastcgi_split_path_info ^((?U).+\.php)(/?.+)$;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
include fastcgi_params;
}
}
Building an environment
1. Start PHP image
docker run -p 9000:9000 --name myphp \
-v /docker/www/:/var/www/html/ \
--privileged=true \
-d php:7.1.0-fpm
#View the IP address of the php imagedocker inspect --format='{{.}}' myphp
172.17.0.2
#Modify the configuration file so that the value of fastcgi_pass is 172.17.0.2:9000
vim /docker/nginx//
fastcgi_pass 172.17.0.2:9000;
2. Start nginx image
docker run -p 80:80 --name mynginx \ -v /docker/www:/usr/share/nginx/html \ -v /docker/nginx/:/etc/nginx/ \ --privileged=true \ -d nginx
3. Check the running status of the mirror
docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 93213e1eac73 nginx "nginx -g 'daemon off" 3 seconds ago Up 2 seconds 0.0.0.0:80->80/tcp mynginx e93281652098 php:7.1.0-fpm "docker-php-entrypoin" 8 minutes ago Up 8 minutes 0.0.0.0:9000->9000/tcp myphp
4. Generate php test files
echo "<?php phpinfo();" > /docker/www/
Browser access http://localhost/ Verification
nginx virtual machine configuration
Taking configuring a virtual machine as an example, the project directory address is /docker/www/
vim /docker/nginx//
# The example content is as follows
server {
listen 80;
server_name ;
root /usr/share/nginx/html//;
location / {
index ;
autoindex off;
}
location ~ \.php(.*)$ {
root /var/www/html//;
fastcgi_pass 172.17.0.2:9000;
fastcgi_index ;
fastcgi_split_path_info ^((?U).+\.php)(/?.+)$;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
include fastcgi_params;
}
}
#Restart nginx image
docker restart mynginx
Commonly used docker commands
1. Stop all running containers
docker kill $(docker ps -a -q)
2. Delete all containers that have stopped running
docker rm $(docker ps -a -q)
3. Check the container running status
docker stats
4. Enter the container for command line operations
docker exec -it content-name-or-id /bin/bash
Frequently Asked Questions
In CentOS7 environment, because of the host's SELINUX, the configuration file () cannot be accessed in the nginx container, and the container cannot provide web services.
Solution:
#########################################Switch off SELINUX on host host#Temporary Closesetenforce 0 #Permanently close Modify /etc/sysconfig/selinux fileSELINUX=disabled #################### Method 2#####################Run containers in privileged way#--privileged parameter is truedocker run -it --privileged=true -d nginx
