这就是你日日夜夜想要的docker！！！---------Dockerfile构建nginx、Tomcat、MySQL镜像

[root@docker ~]# mkdir /nginx
[root@docker ~]# cd /nginx/
[root@docker nginx]# vim Dockerfile
FROM centos:7
RUN yum update -y
RUN yum -y install gcc gcc-c++ make pcre-devel expat-devel perl zlib-devel pcre
RUN useradd -M -s /sbin/nologin nginx
ADD nginx-1.12.2.tar.gz /usr/local
WORKDIR /usr/local/nginx-1.12.2
RUN (./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_stub_status_module) && make &&  make install
ENV PATH /usr/local/nginx/sbin/:$PATH
EXPOSE 80
EXPOSE 443
RUN echo "daemon off;" >> /usr/local/nginx/conf/nginx.conf    '关闭nginx自带的守护进程'
CMD ["/usr/local/nginx/sbin/nginx"]

这里指定的是在centos7下安装  要指定版本
