docker 安装 nginx

# 搜素镜像
[root@iZbp15293q8kgzhur7n6kvZ home]# docker search nginx
NAME                                              DESCRIPTION                                     STARS     OFFICIAL
nginx                                             Official build of Nginx.                        19711     [OK]

# 拉取镜像

# 通过镜像启动容器
# --name 给容器命名
# -p 3500<->80 端口映射(本机端口:容器内端口)，外部通过3500端口访问
[root@iZbp15293q8kgzhur7n6kvZ home]# docker run -d --name mynginx -p 3500:80 nginx

<!DOCTYPE html>
<html>
<head>
<title>Welcome to nginx!</title>
<style>
html { color-scheme: light dark; }
body { width: 35em; margin: 0 auto;
font-family: Tahoma, Verdana, Arial, sans-serif; }
</style>
</head>
<body>
<h1>Welcome to nginx!</h1>
<p>If you see this page, the nginx web server is successfully installed and
working. Further configuration is required.</p>

<p>For online documentation and support please refer to
<a href="http://nginx.org/">nginx.org</a>.<br/>
Commercial support is available at
<a href="http://nginx.com/">nginx.com</a>.</p>

<p><em>Thank you for using nginx.</em></p>
</body>
</html>

这样就完成 nginx 的安装

也可以在外部浏览器访问，输入地址服务器公网ip:3500即可访问，如果无法访问说明没有配置安全组，需要在安全组中把3500端口开放

在这里插入图片描述

docker 安装 elasticsearch

# -p 可以同时暴露多个端口
# -e 环境配置，一般在镜像的文档中查看  hub.docker.com
[root@iZbp15293q8kgzhur7n6kvZ home]# docker run -d --name myelastaicsearch -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" elasticsearch:7.8.0
