操作系统：阿里云esc实例centos7.4

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

一.创建带有swoole-redis-pdo_mysql-gd扩展的docker image

1.创建dockerfile文件

? 1 vim dockerfile

2.在dockerfile文件写入

? 1 2 3 4 5 6 7 8 9 10 11 12 13 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.创建自定义的php镜像，主要不要漏了最后的 '.'，是指定当前目录构建镜像

? 1 docker build -t myphp4 .

运行指令，由于网络问题等，需要等比较长的时间，成功后会出现类似下面的代码

...
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 的自定义myphp4 image创建成功！

二.创建docker-compose.yml文件

? 1 2 3 mkdir pnsmr cd pnsmr vim docker-compose.yml

写入下面代码

? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 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"

运行指令

? 1 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，已开启nginx mysql redis php 服务

三.修改各服务配置文件

1.浏览器输入 127.0.0.1:9998 #此处应输入你的服务器ip地址，可以看到下图

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

? 1 docker inspect -f '{{.name}} - {{range .networksettings.networks}}{{.ipaddress}}{{end}}' $(docker ps -aq)

此指令可以查看所有用docker-compose 开启的容器的ip，结果类似下图，可以用对应的ip地址进行内部通讯

3.复制nginx容器的配置文件出来，并修改替换,使nginx能解析php

? 1 2 docker cp pnsmr_nginx_1:/etc/nginx/conf.d/default.conf nginx.conf vim nginx.conf

修改为下列代码

? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 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;#此处需要填写你的php容器的docker内部通讯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 #将修改好的配置文件拷贝到容器里 docker container stop pnsmr_nginx_1 docker container start pnsmr_nginx_1 #重启nginx容器使配置文件生效 vim /var/www/html/index.php #在服务器本地目录新建 index.php 文件，输入<?php phpinfo(); 并保存 vim /var/www/html/index.html #在服务器本地目录新建 index.html 文件，输出helloworld

访问127.0.0.1:9998, html文件解析正常

访问127.0.0.1:9998/index.php，php文件解析正常

4.测试mysql，redis是否生效

? 1 2 3 4 5 6 vim /var/www/html/redis.php #用于测试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');

访问127.0.0.1:9998/redis.php，redis已生效

进入mysql容器

? 1 docker exec -it pnsmr_mysql_1 bash

进入mysql并更改root用户密码

创建测试文件

? 1 2 3 4 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);

访问127.0.0.1：9998/mysql.php，mysql已生效

四.总结

虽然环境是配置成功了，并可以用docker-compose up 指令一键生成，但是还要改各容器的配置文件，仍然不够方便，需要优化；另外docker的集群，堆栈功能也没用上，后面再继续学习.
