docker搭建php7.1+nginx+swoole+mysql+redis4.0環境的辦法

操作系統：阿里雲esc實例centos7.4

軟件：docker-ce version 18.09.3, docker-compose version 1.23.2

一.創建帶有swoole-redis-pdo_mysql-gd擴展的docker image

1.創建dockerfile文件

vim dockerfile

2.在dockerfile文件寫入

From php:7.1-fpm
RUN apt-get update && apt-get install -y \
 libfreetype6-dev \
 libjpeg62-turbo-dev \
 libpng-dev \
&& docker-php-ext-install -j$(nproc) iconv \
&& docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ \
&& docker-php-ext-install -j$(nproc) gd \
&& docker-php-ext-configure pdo_mysql \
&& docker-php-ext-install pdo_mysql \
&& pecl install redis-4.3.0 \
&& pecl install swoole \
&& docker-php-ext-enable redis swoole

3.創建自定義的php鏡像，主要不要漏了最後的 ‘.’，是指定當前目錄構建鏡像

docker build -t myphp4 .

運行指令，由於網路問題等，需要等比較長的時間，成功後會出現類似下面的代碼

…

Build process completed successfully

Installing ‘/usr/local/include/php/ext/swoole/config.h’

Installing ‘/usr/local/lib/php/extensions/no-debug-non-zts-20160303/swoole.so’

install ok: channel://pecl.php.net/swoole-4.3.1

configuration option “php_ini” is not set to php.ini location

You should add “extension=swoole.so” to php.ini

Successfully built 2f2f332d73ce

Successfully tagged myphp4:latest

至此docker 的自定義myphp4 image創建成功！

二.創建docker-compose.yml文件

mkdir pnsmr
cd pnsmr
vim docker-compose.yml

寫入下面代碼

version: '3.0'
services:
nginx:
 image: "nginx:latest"
 ports:
 - "10000:80"
 volumes:
 - /var/www/html:/usr/share/nginx/html
php-fpm:
 image: "myphp4"
 volumes:
 - /var/www/html:/usr/share/nginx/html
mysql:
 image: "mysql:latest"
redis:
 image: "redis:4.0"

運行指令

docker-compose up -d

成功可以看到

WARNING: The Docker Engine you’re using is running in swarm mode.

Compose does not use swarm mode to deploy services to multiple nodes in a swarm. All containers will be scheduled on the current node.

To deploy your application across the swarm, use `docker stack deploy`.

Creating network “pnsmr_default” with the default driver

Creating pnsmr_php-fpm_1 … done

Creating pnsmr_redis_1 … done

Creating pnsmr_mysql_1 … done

Creating pnsmr_nginx_1 … done

至此，已開啟nginx mysql redis php 服務

三.修改各服務配置文件

1.瀏覽器輸入 127.0.0.1:9998 #此處應輸入你的服務器ip地址，可以看到下圖

2.接下來要修改容器里nginx的配置文件，先使用指令查看各容器的docker IP地址

docker inspect -f '{{.Name}} - {{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' $(docker ps -aq)

此指令可以查看所有用docker-compose 開啟的容器的ip，結果類似下圖，可以用對應的ip地址進行內部通訊

3.復制nginx容器的配置文件出來，並修改替換,使nginx能解析php

docker cp pnsmr_nginx_1:/etc/nginx/conf.d/default.conf nginx.conf
vim nginx.conf

修改為下列代碼

server {
 listen 80;
 server_name localhost;
 #charset koi8-r;
 #access_log /var/log/nginx/host.access.log main;
 location / {
 root /usr/share/nginx/html;
 index 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 html;
 fastcgi_pass 172.24.0.3:9000;#此處需要填寫你的php容器的docker內部通訊ip
 fastcgi_index index.php;
 fastcgi_param SCRIPT_FILENAME /usr/share/nginx/html/$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;
 #}
}
docker cp nginx.conf pnsmr_nginx_1:/etc/nginx/conf.d/default.conf #將修改好的配置文件拷貝到容器里
docker container stop pnsmr_nginx_1 
docker container start pnsmr_nginx_1 #重啟nginx容器使配置文件生效
vim /var/www/html/index.php #在服務器本地目錄新建 index.php 文件，輸入<?php phpinfo(); 並保存
vim /var/www/html/index.html #在服務器本地目錄新建 index.html 文件，輸出helloworld

訪問127.0.0.1:9998, html文件解析正常

訪問127.0.0.1:9998/index.php，php文件解析正常

4.測試mysql，redis是否生效

vim /var/www/html/redis.php #用於測試redis是否配置成功
<?php
$redis = new Redis();
$redis->connect("172.24.0.4",6379);
$redis->set('test','this is a test for redis');
echo $redis->get('test');

訪問127.0.0.1:9998/redis.php，redis已生效

進入mysql容器

docker exec -it pnsmr_mysql_1 bash

進入mysql並更改root用戶密碼

創建測試文件

vim /var/www/html/mysql.php
<?php
$pdo = new PDO('mysql:host=172.24.0.2;dbname=mysql;port=3306','root','root123');
var_dump($pdo);

訪問127.0.0.1：9998/mysql.php，mysql已生效

四.總結

雖然環境是配置成功了，並可以用docker-compose up 指令一鍵生成，但是還要改各容器的配置文件，仍然不夠方便，需要優化；另外docker的集群，堆棧功能也沒用上，後面再繼續學習.
