这里将详细讲述nginx和php的构建过程,以及构建过程中用到的所有工具包和配置文件

首先介绍nginx的构建,查看nginx的Dockerfile:

[root@docker nginx]# cat Dockerfile 
FROM centos_init:v2

MAINTAINER json_hc@163.com

RUN useradd -M -s /sbin/nologin www
ADD nginx-1.8.1.tar.gz /usr/local/src

RUN yum install libxslt-devel -y gd gd-devel GeoIP GeoIP-devel pcre pcre-devel

WORKDIR /usr/local/src/nginx-1.8.1
RUN ./configure --user=www --group=www --prefix=/usr/local/nginx --with-file-aio --with-ipv6 --with-http_ssl_module  --with-http_spdy_module --with-http_realip_module    --with-http_addition_module    --with-http_xslt_module   --with-http_image_filter_module    --with-http_geoip_module  --with-http_sub_module  --with-http_dav_module --with-http_flv_module    --with-http_mp4_module --with-http_gunzip_module  --with-http_gzip_static_module  --with-http_auth_request_module  --with-http_random_index_module   --with-http_secure_link_module   --with-http_degradation_module   --with-http_stub_status_module && make && make install

COPY www.conf /usr/local/nginx/conf/vhost/www.conf

EXPOSE 80

CMD ["/usr/local/nginx/sbin/nginx","-g","daemon off;"]

从上面的基础镜像可以看见是centos_init:v2,这里贴出该镜像的Dockerfile:

技术分享图片
[root@docker nginx]# cat ../init/Dockerfile
# base image
FROM centos

# MAINTAINER
MAINTAINER json_hc@163.com

# backup CentOS-Base.repo to CentOS-Base.repo.bak
RUN mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak

# add epel and aliyun repo to /etc/yum.repos.d
COPY CentOS7-Base-163.repo /etc/yum.repos.d/CentOS7-Base-163.repo
COPY epel-release-latest-7.noarch.rpm /etc/yum.repos.d/

# install epel.repo
WORKDIR /etc/yum.repos.d/
RUN yum install -y epel-release-latest-7.noarch.rpm 
RUN yum clean all
 
# running required command
RUN yum install -y gcc gcc-c++ glibc make autoconf openssl openssl-devel ntpdate crontabs

# change timzone to Asia/Shanghai
RUN cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

centos_init:v2镜像添加了repo的环境和编译的环境,而centos镜像就是初始的官方镜像

下面回归到nginx的构建文件:

从nginx的Dockerfile文件中可以看出,安装nginx采用的编译安装,创建了用户www和安装了nginx的一些依赖包,copy了一些配置文件到镜像中,这里

用到的配置文件将会全部放置到github上供参考,然后通过Dockerfile进行构建nginx镜像:

# docker build -t nginx:v1 .

这里需要介绍配置文件:

技术分享图片
[root@docker nginx]# cat www.conf 
server {
    listen   80;
    root /usr/local/nginx/html;
    index index.htm index.html index.php;
    location ~ \.php$ {
        root /usr/local/nginx/html;
        fastcgi_pass php:9000;
        fastcgi_index index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include fastcgi_params;
    } 
}
技术分享图片

可以看见fastcgi_pass php:9000;

这是因为php也是一个容器,和nginx是隔离的,后面nginx将会通过--link的方式与php镜像进行互联访问

查看php的Dockerfile文件:

[root@docker php]# cat Dockerfile 
FROM centos_init:v2

MAINTAINER json_hc@163.com

ADD libmcrypt-2.5.7.tar.gz /usr/local/src

WORKDIR /usr/local/src/libmcrypt-2.5.7
RUN ./configure && make && make install

ADD php-5.6.30.tar.bz2 /usr/local/src

RUN yum -y install libxml2 libxml2-devel bzip2 bzip2-devel libjpeg-turbo libjpeg-turbo-devel libpng libpng-devel freetype freetype-devel zlib zlib-devel libcurl libcurl-devel

WORKDIR /usr/local/src/php-5.6.30
RUN ./configure --prefix=/usr/local/php --with-pdo-mysql=mysqlnd --with-mysqli=mysqlnd --with-mysql=mysqlnd --with-openssl --enable-mbstring --with-freetype-dir --with-jpeg-dir --with-png-dir --with-mcrypt --with-zlib --with-libxml-dir=/usr --enable-xml  --enable-sockets --enable-fpm --with-config-file-path=/usr/local/php/etc --with-bz2 --with-gd && make && make install


COPY php.ini-production /usr/local/php/etc/php.ini
COPY php-fpm.conf.default /usr/local/php/etc/php-fpm.conf

RUN useradd -M -s /sbin/nologin php
RUN sed -i -e ‘s@;pid = run/php-fpm.pid@pid = run/php-fpm.pid@g‘ -e ‘s@nobody@php@g‘ -e ‘s@listen = 127.0.0.1:9000@listen = 0.0.0.0:9000@g‘ /usr/local/php/etc/php-fpm.conf
RUN sed -i ‘s@;daemonize = yes@daemonize = no@g‘ /usr/local/php/etc/php-fpm.conf


EXPOSE 9000

CMD ["/usr/local/php/sbin/php-fpm"]

构建的服务必须运行在前台,而对于nginx来说:

daemon off表示将后台运行关闭了,于是运行在前台

而对于phh:sed -i ‘s@;daemonize = yes@daemonize = no@g‘ /usr/local/php/etc/php-fpm.conf

这里也是将daemon模式关闭了,于是/usr/local/php/sbin/php-fpm运行在前台

 开始进行构建php:

[root@docker php]# docker build -t php .

查看生成的镜像:

[root@docker php]# docker images 
REPOSITORY                                         TAG                 IMAGE ID            CREATED             SIZE
php                                                latest              8902ce599658        5 minutes ago       1.08GB
nginx                                              latest              c3babfeba09b        22 minutes ago      578MB

利用构建的镜像启动php、nginx服务:

[root@docker php]# docker run -d --name=php -v /www:/usr/local/nginx/html php
538d9866defefe8c818fbebc7109a1cf8d271583f7ce6d14d4483a103a212903
[root@docker php]# docker run -d --name=nginx -p80:80 -v /www:/usr/local/nginx/html --link=php:php nginx
c476e0e2b37f5400ea2175b9a3fc61636190727576187f3feb9248fea37ffd81

上面启动php的容器时,使用了-v进行映射,如果这里不进行映射,那么php的程序会启动,但是遇到php结尾的文件将不会解析,出现file not found的错误

查看容器状态:

[root@docker php]# docker ps -a
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMES
c476e0e2b37f        nginx               "/usr/local/nginx/..."   11 seconds ago      Up 10 seconds       0.0.0.0:80->80/tcp       nginx
538d9866defe        php                 "/usr/local/php/sb..."   39 seconds ago      Up 38 seconds       9000/tcp                 php

网站目录结构:

[root@docker www]# tree .
.
├── index.html
└── test.php

进入到php容器查看hosts文件:

[root@docker php]# docker exec -it php /bin/bash
[root@538d9866defe php-5.6.30]# cat /etc/hosts
127.0.0.1       localhost
::1     localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
172.17.0.4      538d9866defe

查看nginx的hosts文件:

[root@docker php]# docker exec -it nginx /bin/bash
[root@c476e0e2b37f nginx-1.8.1]# cat /etc/hosts
127.0.0.1       localhost
::1     localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
172.17.0.4      php 538d9866defe
172.17.0.5      c476e0e2b37f

可以看见有一条php的解析,这就是为什么nginx能够和php进行通信的缘由(通过--link进行指定)
