前言

tomcat部署web项目非常方便，把war包放到webapps目录就可以了。本篇使用docker快速搭建一个tomcat环境

下载tomcat镜像

拉取官方最新版tomcat镜像

[root@yoyo ~]# docker pull tomcat

运行容器

使用docker run 运行一个tomcat的容器

  • --name yoyotomcat 容器重命名yoyotomcat
  • -p 8090:8080 容器的8080端口映射到主机的8090端口
  • -v ~/yoyo/tomcat/webapps/jenkins:/usr/local/tomcat/webapps/jenkins 容器的/usr/local/tomcat/webapps/jenkins 目录挂载到本机~/yoyo/tomcat/webapps/jenkins
  • -d 挂后台运行

docker run --name yoyotomcat -p 8090:8080 -v ~/yoyo/tomcat/webapps/jenkins:/usr/local/tomcat/webapps/jenkins -d tomcat

运行成功后 docker ps查看已运行容器

[root@yoyo jenkins]# docker run --name yoyotomcat -p 8090:8080 -v ~/yoyo/tomcat/webapps/jenkins:/usr/local/tomcat/webapps/jenkins -d tomcat

[root@yoyo jenkins]# docker ps

[root@yoyo jenkins]#

如果用的是阿里云服务器，需在后台开放8090端口，这样在浏览器输入http://主机ip:8090就能访问到tomcat首页了

docker学习4-docker安装tomcat环境和部署war包

部署war包

tomcat环境已经部署完成，接下来把war包放到tomcat下的webapps目录就可以了，也就是/usr/local/tomcat/webapps。
前面启动的时候，/usr/local/tomcat/webapps/jenkins目录是挂载到本机的~/yoyo/tomcat//webapps/jenkins目录。
只需下载jenkins.war放到jenkins目录就可以了

  • cd 到~/yoyo/tomcat/webapps/jenkins/目录
  • wget 下载jenkins.war
  • jar -xvf 解压jenkins.war
[root@yoyo jenkins]# cd ~/yoyo/tomcat/webapps/jenkins/
[root@yoyo jenkins]# wget http://mirrors.jenkins-ci.org/war/latest/jenkins.war

接着重启tomcat容器就可以生效了

docker restart yoyotomcat

访问jenkins

浏览器输入访问地址:http://主机ip:8090/jenkins就能访问到主页面了
