在CentOS7下从0开始搭建docker并发布tomcat项目

一切从0开始，我也是个小白：

1.检查你的系统是不是高于3.8的内核，如果没有请升级CentOS7或者Ubuntu 14

\#uname -a

2.CentOS7下安装docker

\#yum -y install docker

3.查看docker版本

\#docker version

4.启动docker服务

\#docker service start

5.查看本地镜像

\#docker images

6.如果没有本地镜像，可以下载一个centos7的镜像来作为基础运行环境

\#docker pull centos:7.2.1511

7.再次查看本地镜像

\#docker images

**\[plain\]** [view plain][] [copy][view plain]

1.  REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE  
2.  docker.io/centos    7.2.1511            feac5e0dfdb2        8 months ago        194.6 MB

8.在本地先备好jdk和tomcat，此处采用jdk1.7和tomcat7

\#cd /root/software/

\#wget http://zhibo100.oss-cn-hangzhou.aliyuncs.com/software/jdk-7u79-linux-x64.tar.gz

\#wget http://zhibo100.oss-cn-hangzhou.aliyuncs.com/software/apache-tomcat-7.0.59.tar.gz

需要其他版本的jdk和tomcat操作方法类似。

9.挂载宿主主机到镜像容器的/mnt/software/下：

\#docker run -i -t -v /root/software/:/mnt/software/  --privileged=true  feac5e /bin/bash

10.进入到/mnt/software/下解压jdk和tomcat并将其移动到/opt/目录下

\#cd /mnt/software/

\#tar -zxvf jdk\-7u79-linux-x64.tar.gz

\#tar -zxvf apache-tomcat-7.0.59.tar.gz

\#mv jdk1.7.0\_79/ /opt/jdk

\#mv apache-tomcat-7.0.59 /opt/tomcat

11.配置JAVA环境变量并检测

\#vi ~/.bashrc

在文件末尾加上

export JAVA\_HOME=/opt/jdk  
export PATH=$JAVA\_HOME/bin:$PATH  
export CLASSPATH=.:$JAVA\_HOME/lib/dt.jar:$JAVA\_HOME/lib/tools.jar

保存退出

\#source ~/.bashrc

\#java -version

**\[plain\]** [view plain][] [copy][view plain]

1.  java version "1.7.0\_79"  
2.  Java(TM) SE Runtime Environment (build 1.7.0\_79-b15)  
3.  Java HotSpot(TM) 64-Bit Server VM (build 24.79-b02, mixed mode)

12.编写系统启动脚本并赋予权限

\#vi /root/run.sh

加入以下代码

\#!/bin/bash  
source ~/.bashrc

sh /opt/tomcat/bin/catalina.sh run

退出保存后 给予用户这个文件夹资源权限

\#chmod u+x /root/run.sh

13.退出容器，并查看确认没有正在运行的容器

\#exit

\#docker ps

14.查询所有容器

\#docker ps -a

**\[plain\]** [view plain][] [copy][view plain]

1.  CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS                          PORTS               NAMES  
2.  ee0ee8ac3a93        feac                "/bin/bash"         13 minutes ago      Exited (0) About a minute ago                       sad\_noyce

15.根据当前的容器ID创建新的镜像

\#docker commit ee0ee sdzn.com/tomcat:0.1

16.查看当前的镜像

\#docker images

**\[plain\]** [view plain][] [copy][view plain]

1.  REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE  
2.  sdzn.com/tomcat     0.1                 af0647ada992        56 seconds ago      514.6 MB  
3.  docker.io/centos    7.2.1511            feac5e0dfdb2        8 months ago        194.6 MB

17.以守护进程方式启动新的镜像并传入启动参数

\#docker run -d -p 58080:8080 --name tomcat1 sdzn.com/tomcat:0.1 /root/run.sh

18.查看正在运行的镜像

\#docker ps

**\[plain\]** [view plain][] [copy][view plain]

1.  CONTAINER ID        IMAGE                 COMMAND             CREATED             STATUS              PORTS                     NAMES  
2.  10fe153d9d6d        sdzn.com/tomcat:0.1   "/root/run.sh"      14 seconds ago      Up 6 seconds        0.0.0.0:58080->8080/tcp   tomcat1

19.访问镜像：

http://127.0.0.1:58080

![Center][]  
  
20.停止容器并移除

\#docker ps -a

**\[plain\]** [view plain][] [copy][view plain]

1.  CONTAINER ID        IMAGE                 COMMAND             CREATED             STATUS                      PORTS                     NAMES

3.  10fe153d9d6d        sdzn.com/tomcat:0.1   "/root/run.sh"      6 minutes ago       Up 6 minutes                0.0.0.0:58080->8080/tcp   tomcat1  
4.  ee0ee8ac3a93        feac                  "/bin/bash"         25 minutes ago      Exited (0) 13 minutes ago                             sad\_noyce
