docker学习5-docker安装tomcat环境和部署war包

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
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                               NAMES

[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

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

[root@yoyo jenkins]#

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

方法二:不挂载运行容器

上面是通过挂载tomcat下的webapps目录,在本机上把war包放进去的方式。如果不挂载容器的目录,试了下也是可以把war包放进去的 一个tomca镜像可以启动多个容器实例,可以再启动一个yytomcat的容器实例,映射到主机的8091端口

[root@yoyo jenkins]# docker run --name yytomcat -p 8091:8080 -d tomcat
08af0192b961f1ba1bb1bf1edada968822f3143e5f57c59c396fd3fd948e7529
[root@yoyo jenkins]# docker   ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                               NAMES
08af0192b961        tomcat              "catalina.sh run"        3 hours ago         Up 3 hours          0.0.0.0:8091->8080/tcp              yytomcat
1d07763a6eaa        tomcat              "catalina.sh run"        4 hours ago         Up 3 hours          0.0.0.0:8090->8080/tcp              yoyotomcat
643c1f7c970c        mysql:5.7           "docker-entrypoint.s…"   11 hours ago        Up 4 hours          33060/tcp, 0.0.0.0:3309->3306/tcp   yoyomysql
37a3b50d151c        mysql:5.6           "docker-entrypoint.s…"   28 hours ago        Up 4 hours          0.0.0.0:3308->3306/tcp              mymysql
[root@yoyo jenkins]#

启动完成后在浏览器输入http://主机ip:8091就可以访问到tomcat首页了,接着用docker cp 把本机的war包复制到yytomcat容器里面

接着前面下载jenkins.war并解压到~/yoyo/tomcat/webapps/jenkins/目录步骤

  • docker cp 复制 jenkins整个目录到 容器的/usr/local/tomcat/webapps/jenkins目录
  • docker exec -it yytomcat /bin/bash 进入运行容器的交互环境
  • cd 到tomcat容器的webapps/jenkins目录,查看到已经复制成功
  • exit 退出容器
  • docker restart 重启容器
[root@yoyo ~]# docker cp ~/yoyo/tomcat/webapps/jenkins/ yytomcat:/usr/local/tomcat/webapps/jenkins
[root@yoyo ~]# docker exec -it yytomcat /bin/bash
root@08af0192b961:/usr/local/tomcat# cd webapps/jenkins
root@08af0192b961:/usr/local/tomcat/webapps/jenkins# ls
ColorFormatter.class         LogFileOutputStream.class        MainDialog$1$1.class  bootstrap      favicon.ico  jsbundles
JNLPMain.class             META-INF                MainDialog$1.class      css          help           robots.txt
LogFileOutputStream$1.class  Main$FileAndDescription.class  MainDialog.class      dc-license.txt  images       scripts
LogFileOutputStream$2.class  Main.class                WEB-INF          executable      jenkins.war  winstone.jar
root@08af0192b961:/usr/local/tomcat/webapps/jenkins#
root@08af0192b961:/usr/local/tomcat/webapps/jenkins# exit
exit
[root@yoyo ~]# docker restart yytomcat
yytomcat
[root@yoyo ~]#

浏览器输入访问地址:http://主机ip:8091/jenkins就能访问到主页面了
