docker-compose部署php项目实例详解

1.制定特定扩展的PHP镜像

sudo mkdir -p /www/docker

sudo cd /www/docker

sudo vi Dockerfile

FROM php:7.2-fpm-alpine

RUN sed -i 's/dl-cdn.alpinelinux.org/mirrors.aliyun.com/g' /etc/apk/repositories

RUN apk update && apk add --no-cache --virtual .build-deps \

&& docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ \

&& docker-php-ext-install -j"$(getconf _NPROCESSORS_ONLN)" gd \

&& pecl install -o -f redis \

&& rm -rf /tmp/pear \

&& docker-php-ext-enable redis \

&& rm -r /var/cache/apk/*

EXPOSE 9000

2.编写yml文件

sudo vi docker-compose.yml

version: '3.1'

services:

nginx:

image: nginx

container_name: nginx

restart: always

ports:

- "80:80"

- "443:443"

volumes:

- /www/data/nginx/conf.d:/etc/nginx/conf.d

- /www/default:/www/default

networks:

csl:

ipv4_address: 172.18.0.2

php:

image: php:7.2-fpm-alpine-dcwd

container_name: php7.2

restart: always

volumes:

- /www/default:/www/default

networks:

csl:

ipv4_address: 172.18.0.3 mysql5:

image: mysql:5.7

container_name: mysql5

restart: always

ports:

- "3306:3306"

environment:

MYSQL_ROOT_PASSWORD: thisyourpassword

volumes:

- /www/data/mysql/mysql5:/var/lib/mysql #- /www/data/mysql/mysql5/conf/my.cnf:/etc/my.cnf

#- /www/data/mysql/mysql5/init:/docker-entrypoint-initdb.d

networks:

csl:

ipv4_address: 172.18.0.4 mysql8:

image: mysql:8

container_name: mysql8

restart: always

environment:

MYSQL_ROOT_PASSWORD: thisyourpassword

volumes:

- /www/data/mysql/mysql8:/var/lib/mysql networks:

csl:

ipv4_address: 172.18.0.5

networks:

csl:

driver: bridge

ipam:

config:

- subnet: 172.18.0.0/16

3.配置default.conf文件

sudo vi /www/data/nginx/default.conf

server {

listen    80;

server_name localhost;

#charset koi8-r;

#access_log /var/log/nginx/host.access.log main;

location / {

root  /www/default;

index index.php index.html index.htm;

}

#error_page 404       /404.html;

# redirect server error pages to the static page /50x.html

#

error_page  500 502 503 504 /50x.html;

location = /50x.html {

root  /usr/share/nginx/html;

}

# proxy the PHP scripts to Apache listening on 127.0.0.1:80

#

#location ~ \.php$ {

#  proxy_pass  http://127.0.0.1;

#}

# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000

#

location ~ \.php$ {

root      /www/default;

fastcgi_pass  php7.2:9000;#php容器名或者php容器ip

fastcgi_index index.php;

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

include    fastcgi_params;

}

# deny access to .htaccess files, if Apache's document root

# concurs with nginx's one

#

#location ~ /\.ht {

#  deny all;

#}

}

4.修改mysql允许远程连接并新建数据库

docker exec -it mysql5 bash

mysql -u root -p

use mysql;

update user set host='%' where user='root';

flush privileges;

5.创建并且启动容器

docker-compose up -d

6.新建index.php测试mysql连接

<?php

$con = mysqli_connect("172.18.0.4", "root", "thisyourpassword", "shop");

if ($con) {

echo '连接 MYSQL 成功';

} else {

echo "连接 MySQL 失败: " . mysqli_connect_error();

} mysqli_close($con);
