在本篇文章里小编给大家整理了关于docker-compose部署php项目的相关实例以及代码内容，有需要的朋友们可以学习参考下。

1.制定特定扩展的PHP镜像

sudo mkdir -p /www/docker

sudo cd /www/docker

sudo vi Dockerfile

1. FROM php:7.2-fpm-alpine
2. MAINTAINER diaocheweide
3. RUN sed -i 's/dl-cdn.alpinelinux.org/mirrors.aliyun.com/g' /etc/apk/repositories
4. RUN apk update && apk add --no-cache --virtual .build-deps \
5. $PHPIZE_DEPS \
6. curl-dev \
7. imagemagick-dev \
8. libtool \
9. libxml2-dev \
10. postgresql-dev \
11. sqlite-dev \
12. libmcrypt-dev \
13. freetype-dev \
14. libjpeg-turbo-dev \
15. libpng-dev \
16. && apk add --no-cache \
17. curl \
18. imagemagick \ mysql-client \
19. postgresql-libs \
20. && pecl install imagick \
21. && pecl install mcrypt-1.0.1 \
22. && docker-php-ext-install zip \
23. && docker-php-ext-install pdo_mysql \
24. && docker-php-ext-install opcache \
25. && docker-php-ext-install mysqli \
26. && docker-php-ext-enable mcrypt \
27. && docker-php-ext-enable imagick \
28. && docker-php-ext-install \
29. curl \
30. mbstring \
31. pdo \
32. pdo_mysql \
33. pdo_pgsql \
34. pdo_sqlite \
35. pcntl \
36. tokenizer \
37. xml \
38. zip \
39. && docker-php-ext-install -j"$(getconf _NPROCESSORS_ONLN)" iconv \
40. && docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ \
41. && docker-php-ext-install -j"$(getconf _NPROCESSORS_ONLN)" gd \
42. && pecl install -o -f redis \
43. && rm -rf /tmp/pear \
44. && docker-php-ext-enable redis \
45. && rm -r /var/cache/apk/*
46. EXPOSE 9000

2.编写yml文件

sudo vi docker-compose.yml

1. version: '3.1'
2. services:
3. nginx:
4. image: nginx
5. container_name: nginx
6. restart: always
7. ports:
8. - "80:80"
9. - "443:443"
10. volumes:
11. - /www/data/nginx/conf.d:/etc/nginx/conf.d
12. - /www/default:/www/default
13. networks:
14. csl:
15. ipv4_address: 172.18.0.2
16. php:
17. image: php:7.2-fpm-alpine-dcwd
18. container_name: php7.2
19. restart: always
20. volumes:
21. - /www/default:/www/default
22. networks:
23. csl:
24. ipv4_address: 172.18.0.3 mysql5:
25. image: mysql:5.7
26. container_name: mysql5
27. restart: always
28. ports:
29. - "3306:3306"
30. environment:
31. MYSQL_ROOT_PASSWORD: thisyourpassword
32. volumes:
33. - /www/data/mysql/mysql5:/var/lib/mysql #- /www/data/mysql/mysql5/conf/my.cnf:/etc/my.cnf
34. #- /www/data/mysql/mysql5/init:/docker-entrypoint-initdb.d
35. networks:
36. csl:
37. ipv4_address: 172.18.0.4 mysql8:
38. image: mysql:8
39. container_name: mysql8
40. restart: always
41. environment:
42. MYSQL_ROOT_PASSWORD: thisyourpassword
43. volumes:
44. - /www/data/mysql/mysql8:/var/lib/mysql networks:
45. csl:
46. ipv4_address: 172.18.0.5
47. networks:
48. csl:
49. driver: bridge
50. ipam:
51. config:
52. - subnet: 172.18.0.0/16

3.配置default.conf文件

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

1. server {
2. listen 80;
3. server_name localhost;
4. #charset koi8-r;
5. #access_log /var/log/nginx/host.access.log main;
6. location / {
7. root /www/default;
8. index index.php index.html index.htm;
9. }
10. #error_page 404 /404.html;
11. # redirect server error pages to the static page /50x.html
12. #
13. error_page 500 502 503 504 /50x.html;
14. location = /50x.html {
15. root /usr/share/nginx/html;
16. }
17. # proxy the PHP scripts to Apache listening on 127.0.0.1:80
18. #
19. #location ~ \.php$ {
20. # proxy_pass http://127.0.0.1;
21. #}
22. # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
23. #
24. location ~ \.php$ {
25. root /www/default;
26. fastcgi_pass php7.2:9000;#php容器名或者php容器ip
27. fastcgi_index index.php;
28. fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
29. include fastcgi_params;
30. }
31. # deny access to .htaccess files, if Apache's document root
32. # concurs with nginx's one
33. #
34. #location ~ /\.ht {
35. # deny all;
36. #}
37. }

4.修改mysql允许远程连接并新建数据库

1. docker exec -it mysql5 bash
2. mysql -u root -p
3. use mysql;
4. update user set host='%' where user='root';
5. 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

1. <?php
2. $con = mysqli_connect("172.18.0.4", "root", "thisyourpassword", "shop");
3. if ($con) {
4. echo '连接 MYSQL 成功';
5. } else {
6. echo "连接 MySQL 失败: " . mysqli_connect_error();
7. } mysqli_close($con);
