一.创建带有swoole-redis-pdo_mysql-gd扩展的docker image
1.创建dockerfile文件
vim dockerfile
2.在dockerfile文件写入
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.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
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
mkdir pnsmr cd pnsmr vim docker-compose.yml
写入下面代码
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
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
docker inspect -f '{{.name}} - {{range .networksettings.networks}}{{.ipaddress}}{{end}}' $(docker ps -aq)此指令可以查看所有用docker-compose 开启的容器的ip，结果类似下图，可以用对应的ip地址进行内部通讯
3.复制nginx容器的配置文件出来，并修改替换,使nginx能解析php
docker cp pnsmr_nginx_1:/etc/nginx/conf.d/default.conf nginx.conf vim nginx.conf
修改为下列代码
server {
listen 80;
server_name localhost;
#charset koi8-r;
#access_log /var/log/nginx/host.access.log main;
location / {
root /usr/share/nginx/html;
index index.html index.htm;
}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
# proxy the php scripts to apache listening on 127.0.0.1:80
#
#location ~ \.php$ {
# 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
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
docker exec -it pnsmr_mysql_1 bash
进入mysql并更改root用户密码
创建测试文件
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);
访问127.0.0.1：9998/mysql.php，mysql已生效
以上是怎么使用docker搭建php+nginx+swoole+mysql+redis环境的详细内容。更多信息请关注PHP中文网其他相关文章！
