docker-compose部署php項目

1.制定特定擴展的PHP鏡像

sudo mkdir -p /www/docker
sudo cd /www/docker
sudo vi Dockerfile
FROM php:7.2-fpm-alpine

EXPOSE 9000
2.編寫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,拷貝這一步請參考上一篇文章
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允許遠程連接並新建數據庫
docker exec -it mysql5 bash
mysql -u root -p
use mysql;
update user set host='%' where user='root';
flush privileges;
5.創建並且啓動容器
docker-compose up -d
6.新建index.php測試mysql連接
<?php

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

echo '連接 MYSQL 成功';

} else {

echo "連接 MySQL 失敗: " . mysqli_connect_error();

}

mysqli_close($con);
