在实际开发中，我们经常会遇到多台机器配置相同的软件运行环境。
比如配置一个tomcat,mysql...一些环境，其他机器也需要相同的环境时，就会一遍一遍的进行配置，比较麻烦。
而且容器和容器之间是完全隔离的。
在学习的过程中发现Docker可以解决这个问题，所以记录下安装遇到的坑
1、首先我们需要安装linux系统，可以上网
2、接下来需要查看linux内核版本，因为Docker需要Linux 3.10以上的版本
[[email protected] ~]# uname -a
Linux localhost 3.10.0-514.el7.x86_64 #1 SMP Tue Nov 22 16:42:41 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux3、刚装上Linux我们更新下系统
[[email protected] ~]# yum update4、正式安装Docker
[[email protected] ~]# yum install docker然后一直输入y
安装好后，查看是否安装成功
[[email protected] ~]# docker -v
Docker version 1.13.1, build 8633870/1.13.15、接着运行docker服务
[[email protected] ~]# service docker start
Redirecting to /bin/systemctl start docker.service
Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "j
ournalctl -xe" for details.我们发现启动没有成功，根据提示，查看详细内容
[[email protected] ~]# systemctl status docker.service

Hint: Some lines were ellipsized, use -l to show in full.折腾了一段时间后，在网上终于找到了解决办法
6、找到docker-storage文件
[[email protected] ~]# vi /etc/sysconfig/docker如下图
我加了上图用红色圈住的一段代码
7、接着重新启动docker,OK
[[email protected] ~]# systemctl restart docker
[[email protected] ~]# 8、比如我们要装tomcat,输入命令，查找tomcat
[[email protected] ~]# docker search tomcat

[[email protected] ~]# 附上docker仓库网站https://hub.docker.com/
如果使用docker pull xxx来拉取镜像，那么会使用国外的网站，现在我们使用国内的镜像来拉取，会更快的下载,如下
docker pull registry.docker-cn.com/library/xxx9、安装tomcat到本地镜像，使用pull命令

[[email protected] ~]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
docker.io/tomcat latest 41a54fe1f79d 4 weeks ago 463 MB15、如果想使docker在Linux启动的时候也跟着启动，那么输入命令 systemctl enable docker
[[email protected] ~]# systemctl enable docker
Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.16、真正的用docker运行一个tomcat镜像，使用命令 docker run --name mytomcat -d tomcat:latest
[[email protected] ~]# docker run --name mytomcat -d tomcat:latest
1e05e524c6097b1dac4e58821bb220037d40488c5cf9846e37fabd29a3dfb22b17、查看刚才运行的tomat镜像，使用命令 docker ps 查看运行中的容器
[[email protected] ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
1e05e524c609 tomcat:latest "catalina.sh run" About a minute ago Up About a minute 8080/tcp mytomcat18、停止docker容器 使用命令 docker stop 容器ID或者容器名称
[[email protected] ~]# docker stop 1e05e524c609
1e05e524c609可以使用docker ps -a 查看容器中的镜像，已经退出了。
[[email protected] ~]# docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
1e05e524c609 tomcat:latest "catalina.sh run" 5 minutes ago Exited (143) 22 seconds ago mytomcat如果我们想要容器启动，那么我们使用docker start mytomcat命令
19、删除容器 docker rm mytomcat
20、如果想要真正是运行tomcat可以被访问到，那么我们在运行docker的tomcat容器时需要加一些参数，docker run -d -p 8888:8080 tomcat 说明：-d后台运行，-p端口映射，把主机的端口映射到容器中的端口，下面的例子是把8888映射到容器中的8080
[[email protected] ~]# docker run -d -p 8888:8080 tomcat
52f3b94d083eb9669b92e346d489df626b59377327f5d84cc3c55860fcd9614f这样就启动了映射，外部可以访问启动的容器了
[[email protected] ~]# docker ps

52f3b94d083e tomcat "catalina.sh run" 7 minutes ago Up 7 minutes 0.0.0.0:8888->8080/tcp optimistic_albattani20、如果外部访问不了，可能是防火墙的问题，使用命令 service firewalld status 查看防火墙状态
[[email protected] ~]# service firewalld status
