操作系統：阿里云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
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，主要不要漏了最后的 '.'，是指定當前目錄構建鏡像
運行指令，由于網絡問題等，需要等比較長的時間，成功后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
Removing intermediate container ad1420f7554f
---> 2f2f332d73ce
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
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}}' $(docker ps -aq)
此指令可以查看所有用docker-compose 開啟的容器的ip，結果類似下圖，可以用對應的ip地址進行內部通訊
3.復制nginx容器的配置文件出來，并修改替換,使nginx能解析php
docker cp pnsmr_nginx_1:/etc/nginx/conf.d/default.conf nginx.conf
vim nginx.conf
修改為下列代碼
server {
listen 80;
server_name localhost;
#charset koi8-r;
#access_log /var/log/nginx/host.access.log main;
location / {
root /usr/share/nginx/html;
index index.html index.htm;
}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \.php$ {
# 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(); 并保存
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 #用于測試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并更改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，并可以用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，后面再繼續學習.
