## 启动tomcat ##

启动 tomcat 容器，将容器的 8080 端口与外网的 8888端口进行映射

[root@VM-0-7-centos ~]# docker run -d --name artisanTomcat -p 8888:8080 tomcat
    2a0e6e88661732a710d8a30d9fda6d73c25478fe352a59f520cb753da6442f7b
    [root@VM-0-7-centos ~]#

[root@VM-0-7-centos ~]# docker ps

## 访问tomcat ##

访问下试试

![在这里插入图片描述][watermark_type_ZHJvaWRzYW5zZmFsbGJhY2s_shadow_50_text_Q1NETiBA5bCP5bCP5bel5Yyg_size_20_color_FFFFFF_t_70_g_se_x_16 2]

![在这里插入图片描述][18f621e44e364e96bed238e62418c2e9.png]

不应该啊，看看Tomcat下的webapps

--------------------

## 查看webapps & 修复问题 ##

进入 tomcat 容器 ，发现webapps 下面什么都没有 ， 阿里云镜像 默认是最小的镜像，所有不必要的都剔除了，保证最小可运行环境

将webapps.dist 目录下的文件拷贝到 webapps下面 ，然后刷新页面就可以看到tomcat页面了

root@2a0e6e886617:/usr/local/tomcat# cd ..
    root@2a0e6e886617:/usr/local/tomcat# cp -r webapps.dist/* webapps
    root@2a0e6e886617:/usr/local/tomcat# cd webapps

--------------------

## 重新访问tomcat ##

刷新页面，无需重启容器
