3.启动镜像并映射宿主机端口
# docker run -d --name nginx -p 3344:80 ngxin
[root@wangcai ~]# docker run --name ngixn -d -p 3344:80 nginx

4.通过本机地址端口访问 是否启动并映射成功
# curl http:localhost:3344
6367b5ba1058091f81ba0e02deae8004cef8df6bbdfe4826b051f710791cf489
[root@wangcai ~]# curl http://localhost:3344

Docker 安装Tomcat
1.官方命令（用完就删除容器,不推荐需要重新配置容器）
# docker run -it -rm tomcat
2.常用启动命令
# docker run --name tomcat -d -p 8080:8080 tomcat (停止后可以通过docker start asdasd（容器ID启动）)
[root@wangcai ~]# docker run -it -d --name tomcat -p 8080:8080 tomcat
Emulate Docker CLI using podman. Create /etc/containers/nodocker to quiet msg.

3.访问本地，查看是否成功
# curl http://localhost:8080
[root@wangcai ~]# curl localhost:8080
<!doctype html><html lang="en"><head><title>HTTP Status 404 鈥� Not Found</title><style type="text/css">body {font-family:Tahoma,Arial,sans-serif;} h1, h2, h3, b {colorwhite;background-color:#525D76;} h1 {font-size:22px;} h2 {font-size:16px;} h3 {font-size:14px;} p {font-size:12px;} a {color:black;} .line {height:1px;background-color:#525D76;border:none;}</style></head><body><h1>HTTP Status 404 鈥� Not Found</h1><hr class="line" /><p><b>Type</b> Status Report</p><p><b>Description</b> The origin servr did not find a current representation for the target resource or is not willing to disclose that one exists.</p><hr class="line" /><h3>Apache Tomcat/10.0.12</h3></body></html>[root@wangcai ~]#
Docker 安装ES
1.拉取镜像（需要携带版本号，不然拉不下来）
# docker pull docker.io/library/elasticsearch:6.5.0
2.启动命令（携带配置启动，控制es启动内存）
# docker run -it --name es -d -p 9200:9200 -p 9300:9300 -e ES_JAVA_OPTS='-Xms256m -Xmx512m' elasticsearch
[root@wangcai ~]# docker run -it --name es -d -p 9200:9200 -p 9300:9300 -e ES_JAVA_OPTS='-Xms256m -Xmx512m' elasticsearch

3.访问本地，查看是否成功(失败了 我的天,还在找问题)
# curl http://localhost:9200
[root@wangcai ~]# curl localhost:9200
curl: (7) Failed to connect to localhost port 9200: 拒绝连接
Docker 安装MYSQL
1.拉取镜像
# docker pull docker.io/library/mysql
2.在宿主机创建与容器内对应的卷挂载目录
# cd /root
# mkdir mysql
# cd mysql
# mkdir data
# mkdir conf
3.启动命令（携带配置启动，挂载数据文件位置）
# docker run -d --name mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=123456 -v /root/mysql/conf:/etc/mysql/conf.d -v /root/mysql/data:/var/lib/mysql mysql
[root@wangcai mysql]# docker run -d --name mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=123456 -v /root/mysql/conf:/etc/mysql/conf.d -v /root/mysql/data:/var/lib/mysql mysql

# cd /root/mysql/data
# ls
[root@wangcai data]# ls
