2 Tomcat部署

（1）下载并运行

[root@iZwz99sm8v95sckz8bd2c4Z ~]# docker pull tomcat Using default tag: latest latest: Pulling from library/tomcat 6c33745f49b4: Pull complete ef072fc32a84: Pull complete c0afb8e68e0b: Pull complete d599c07d28e6: Pull complete e8a829023b97: Pull complete d04be46a31d1: Pull complete db6007c69c35: Pull complete e4ad4c894bce: Pull complete 248895fda357: Pull complete 277059b4cba2: Pull complete Digest: sha256:57dae7dfb9b62a413cde65334c8a18893795cac70afc3be589c8336d8244655d Status: Downloaded newer image for tomcat:latest docker.io/library/tomcat:latest [root@iZwz99sm8v95sckz8bd2c4Z ~]# docker run -d -p 3335:8080 --name tomcat01 tomcat 7136295a6082cb0f805b025a1471bde02ead4864be3e2c9dcd337b1dde0a3113

（2）进入容器

1.容器中的命令是少了

2.阿里云镜像默认下载的是最小的镜像，保证最小的运行环境。

[root@iZwz99sm8v95sckz8bd2c4Z ~]# docker exec -it tomcat01 /bin/bash root@7136295a6082:/usr/local/tomcat# ls BUILDING.txt CONTRIBUTING.md LICENSE NOTICE README.md RELEASE-NOTES RUNNING.txt bin conf lib logs native-jni-lib temp webapps webapps.dist work root@7136295a6082:/usr/local/tomcat# cd webapps.dist root@7136295a6082:/usr/local/tomcat/webapps.dist# ls ROOT docs examples host-manager manager root@7136295a6082:/usr/local/tomcat/webapps.dist# cd ROOT root@7136295a6082:/usr/local/tomcat/webapps.dist/ROOT# ls RELEASE-NOTES.txt WEB-INF asf-logo-wide.svg bg-button.png bg-middle.png bg-nav.png bg-upper.png favicon.ico index.jsp tomcat.css tomcat.svg root@7136295a6082:/usr/local/tomcat/webapps.dist/ROOT# cd ../../ root@7136295a6082:/usr/local/tomcat# cd webapps root@7136295a6082:/usr/local/tomcat/webapps# ls root@7136295a6082:/usr/local/tomcat/webapps# cp -r /usr/local/tomcat/webapps.dist/* /usr/local/tomcat/webapps/ root@7136295a6082:/usr/local/tomcat/webapps# ls ROOT docs examples host-manager manager root@7136295a6082:/usr/local/tomcat/webapps# exit exit

（3）访问测试

[root@iZwz99sm8v95sckz8bd2c4Z ~]# curl localhost:3335

3 ElasticSearch部署

添加 ’-e ES_JAVA_OPTS="-Xms128m -Xmx512m" ‘ 配置ElasticSearch的虚拟机占用的内存大小。

docker stats 查看资源占用情况

$ docker run -d --name elasticsearch -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" -e ES_JAVA_OPTS="-Xms128m -Xmx512m" elasticsearch:7.6.2

[root@iZwz99sm8v95sckz8bd2c4Z ~]# docker run -d --name elasticsearch01 -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" -e ES_JAVA_OPTS="-Xms128m -Xmx512m" elasticsearch:7.6.2 3b8cd4991814896c523ee67b84ce198e32bd82b1a62d512b198138a58ca946f1 [root@iZwz99sm8v95sckz8bd2c4Z ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 3b8cd4991814 elasticsearch:7.6.2 "/usr/local/bin/dock…" 10 seconds ago Up 6 seconds 0.0.0.0:9200->9200/tcp, 0.0.0.0:9300->9300/tcp elasticsearch01 [root@iZwz99sm8v95sckz8bd2c4Z ~]# docker stats

4 MySQL部署

（1）下载并运行

#拉取并运行容器 docker run -d --name mysql-5.7 -p 3306:3306 -e MYSQL_ROOT_PASSWORD=123456 mysql:5.7

参数说明：

-p 3306:3306 ：映射容器服务的 3306 端口到宿主机的 3306 端口，外部主机可以直接通过宿主机ip:3306 访问到 MySQL 的服务。 MYSQL_ROOT_PASSWORD=123456：设置 MySQL 服务默认账号root 用户的密码。
