检查本地操作系统版本：
[root@node ~]# cat /etc/os-release
NAME="CentOS Linux"
VERSION="7 (Core)"
ID="centos"
ID_LIKE="rhel fedora"
VERSION_ID="7"
PRETTY_NAME="CentOS Linux 7 (Core)"
ANSI_COLOR="0;31"
CPE_NAME="cpe:/o:centos:centos:7"
HOME_URL="https://www.centos.org/"
BUG_REPORT_URL="https://bugs.centos.org/"
CENTOS_MANTISBT_PROJECT="CentOS-7"
CENTOS_MANTISBT_PROJECT_VERSION="7"
REDHAT_SUPPORT_PRODUCT="centos"
REDHAT_SUPPORT_PRODUCT_VERSION="7"
三、检查本地Docker环境
1. 检查本地Docker服务
检查本地Docker服务状态，确保Docker服务正常运行。
[root@node ~]# systemctl status docker
● docker.service - Docker Application Container Engine
Loaded: loaded (/usr/lib/systemd/system/docker.service; enabled; vendor preset: disabled)
Active: active (running) since Mon 2022-10-31 03:28:51 CST; 2 days ago
Docs: https://docs.docker.com
Main PID: 11884 (dockerd)
Tasks: 108
Memory: 2.7G
2. 检查Docker版本
检查Docker版本
[root@server001 ~]# docker version
Client: Docker Engine - Community

API version: 1.41
Go version: go1.18.9

GitCommit: v1.1.4-0-g5fd4c4d
docker-init:

GitCommit: de40ad0
四、搜索docker hub中的tomcat镜像
在docker官方的镜像仓库docker hub中搜索tomcat的容器镜像，
这里直接选择的容器镜像为：tomcat:8.5.46-jdk8-openjdk
[root@node ~]# docker search tomcat

五、下载tomcat镜像
在docker hub中拉取tomcat:8.5.46-jdk8-openjdk镜像。
[root@node tomcat]# docker pull tomcat:8.5.46-jdk8-openjdk
8.5.46-jdk8-openjdk: Pulling from library/tomcat

Status: Downloaded newer image for tomcat:8.5.46-jdk8-openjdk
docker.io/library/tomcat:8.5.46-jdk8-openjdk
六、创建Tomcat容器
1.创建数据目录
创建容器挂载目录
[root@node ~]# mkdir -p /data/tomcat/data
[root@node ~]# chmod -R 777 /data/tomcat/
2.运行Tomcat容器
使用docker-cli快速创建tomcat容器。
[root@node tomcat]# docker run -d --name my_web --restart always -p 7090:8080 -v /data/tomcat/data:/usr/local/tomcat/webapps/ROOT/ tomcat:8.5.46-jdk8-openjdk
26674fb4896f49f26282b3fe21b484d40017d13fd7cc474db5badf57bdb4a865
3.查看Tomcat容器状态
检查tomcat容器的运行状态，确保容器的正常启动。
[root@node data]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
26674fb4896f tomcat:8.5.46-jdk8-openjdk "catalina.sh run" About a minute ago Up About a minute 0.0.0.0:7090->8080/tcp, :::7090->8080/tcp my_web
七、访问Tomcat网页
1.编辑网页内容
编辑一个测试index.html网页文件。
[root@node tomcat]# cd data/
[root@node data]# echo hello > index.html
2.访问tomcat网页
访问地址：http://140.143.163.109:7090/
可以正常访问到网页测试内容时，说明tomcat容器已经正常运行了。
