Docker NGINX + PHP

Docker 多容器组合服务

• 拉取创建好的容器

leo@uLinux:~$ docker pull leodockerpro/nginx:1.0
leo@uLinux:~$ docker pull leodockerpro/php:1.1.1-fpm

---

• 启动 PHP 容器, 让 NGINX 把请求转发到 PHP-FPM

docker run -d --name php -p 9000:9000 -v $(pwd)/html:/usr/share/nginx/html leodockerpro/php:1.1.1-fpm

---

• 查看容器: php 的内网IP地址

docker inspect --format '{{ .NetworkSettings.IPAddress }}' php

这里可以看到为: 172.17.0.2

---

• 使用自定义 Nginx 配置文件, 覆盖到容器的Nginx 配置文件
  $(pwd)/conf/nginx.conf

user  nginx;
worker_processes  1;
worker_rlimit_nofile 65535; 
error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;
events {
    use epoll;
    worker_connections  65535;
}

http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';
    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    keepalive_timeout  65;
    server_tokens off;
    gzip on; 
    gzip_disable "msie6"; 

    server {
        listen    80;       
        server_name  localhost;

        root   /usr/share/nginx/html;
        index  index.html index.htm index.php;

        location / {
            try_files $uri $uri/ /index.php?$args;
        }

        location ~ \.php$ {
            fastcgi_pass   172.17.0.2:9000;
            fastcgi_index  index.php;
            fastcgi_split_path_info ^((?U).+\.php)(/?.+)$;
            fastcgi_param SCRIPT_NAME $fastcgi_script_name;
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
            fastcgi_param PATH_INFO $fastcgi_path_info;
            fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
            include        fastcgi_params;
        }

        error_page   500 502 503 504  /50x.html;
        location ~ /\.ht {
            deny  all;
        }
    }
}

配置文件: http > server > location ~ \.php$ > fastcgi_pass 内容需要和具体的容器地址及端口对应.

• 启动 Nginx 容器

docker run -d --name nginx -p 80:80 -v $(pwd)/html:/usr/share/nginx/html:ro -v $(pwd)/conf/nginx.conf:/etc/nginx/nginx.conf leodockerpro/nginx:1.0

• 使用本地的 $(pwd)/conf/nginx.conf 替代容器里的 NGINX 配置文件.
• 本地的网站目录挂载到 NGINX 容器里的路径和挂载给 PHP 容器的的路径要一致: $(pwd)/html:/usr/share/nginx/html

---

• 查看日志
  创建 phpinfo 脚本:

echo '<?php phpinfo(); ?>' > $(pwd)/html/info.php

打开浏览器, 输入: http://localhost/info.php 进行访问, 即可看到日志和 phpinfo 信息.

日志查看指令: docker logs -f --tail=xx <ImageID|name>

docker logs -f --tail=10 nginx

基本上和 Linux 上 tail -f <file> 一样方便使用.
