主旨
本文使用上一篇文章中说到的dockerfile方式，分别构建一个nginx，一个redis镜像。
环境

linux环境
docker环境

nginx镜像构建
创建目录，并切换至对应目录：

[yunweijia@localhost ~]$ mkdir -pv docker/nginx
mkdir: 已创建目录 "docker"
mkdir: 已创建目录 "docker/nginx"
[yunweijia@localhost ~]$ cd docker/nginx/

nginx安装脚本：

[yunweijia@localhost nginx]$ pwd
/home/yunweijia/docker/nginx
[yunweijia@localhost nginx]$ vim install.s
yum install -y wget tar gcc gcc-c++ make pcre pcre-devel zlib zlib-devel
cd /usr/local/src
wget http://nginx.org/download/nginx-1.14.2.tar.gz
tar -zxf nginx-1.14.2.tar.gz
cd nginx-1.14.2
./configure --prefix=/usr/local/nginx & & make & & make install
\\rm -rf /usr/local/src/*
[yunweijia@localhost nginx]$

nginx启动脚本，记得添加可执行权限：

[yunweijia@localhost nginx]$ pwd
/home/yunweijia/docker/nginx
[yunweijia@localhost nginx]$ vim nginx
#!/bin/bash
/usr/local/nginx/sbin/nginx -g "daemon off; "
[yunweijia@localhost nginx]$ chmod +x nginx
[yunweijia@localhost nginx]$

dockerflie文件：

[yunweijia@localhost nginx]$ pwd
/home/yunweijia/docker/nginx
[yunweijia@localhost nginx]$ vim Dockerfile
FROM centos:7
COPY install.sh /tmp/install.sh
RUN sh /tmp/install.sh
COPY nginx /usr/bin/nginx
ENTRYPOINT ["nginx"]
[yunweijia@localhost nginx]$

构建nginx镜像：

[yunweijia@localhost nginx]$ sudo docker build -t yunweijia:nginx /home/yunweijia/docker/nginx/
# 直至出现如下提示
Successfully built e46b589abaed
Successfully tagged yunweijia:nginx

[yunweijia@localhost nginx]$
[yunweijia@localhost nginx]$ sudo docker stop cde16676029b
cde16676029b
[yunweijia@localhost nginx]$

redis镜像构建
创建目录，并切换至对应目录：

[yunweijia@localhost ~]$ pwd
/home/yunweijia
[yunweijia@localhost ~]$ mkdir -pv docker/redis
mkdir: 已创建目录 "docker/redis"
[yunweijia@localhost ~]$ cd docker/redis/
[yunweijia@localhost redis]$

redis安装脚本：

[yunweijia@localhost redis]$ pwd
/home/yunweijia/docker/redis
[yunweijia@localhost redis]$ vim install.sh
yum install -y wget gcc gcc-c++ make tar openssl openssl-devel cmake
cd /usr/local/src
wget http://download.redis.io/releases/redis-4.0.9.tar.gz
tar -zxf redis-4.0.9.tar.gz
cd redis-4.0.9
make & & make PREFIX=/usr/local/redis install
mkdir -pv /usr/local/redis/conf/
cp redis.conf /usr/local/redis/conf/
\\rm -rf /usr/local/src/*
[yunweijia@localhost redis]$

redis启动脚本，记得添加可执行权限：

[yunweijia@localhost redis]$ pwd
/home/yunweijia/docker/redis
[yunweijia@localhost redis]$ vim redis
#!/bin/bash
/usr/local/redis/bin/redis-server /usr/local/redis/conf/redis.conf
[yunweijia@localhost redis]$
[yunweijia@localhost redis]$ chmod +x redis

Dockerfile文件：

[yunweijia@localhost redis]$ pwd
/home/yunweijia/docker/redis
[yunweijia@localhost redis]$ vim Dockerfile
FROM centos:7
COPY install.sh /tmp/install.sh
RUN sh /tmp/install.sh
COPY redis /usr/bin/redis
ENTRYPOINT ["redis"]
[yunweijia@localhost redis]$

构建redis镜像：

[yunweijia@localhost redis]$ sudo docker build -t yunweijia:redis /home/yunweijia/docker/redis/
# 直至出现如下提示
