docker下tomcat环境搭建

在上一篇文章中介绍了利用Dockerfile创建docker镜像文件，编写的过程中把jdk和tomcat文件都加入到镜像文件中去了。通过以下命令来启动镜像文件。 [root@localhost docker]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE centos base 9d20362732d7 About an hour ago 904.8 MB docker.io/centos latest 970633036444 2 weeks ago 196.7 MB [root@localhost soft]# docker run -tid --name mytomcat -p 80:8080 centos:base 0299abe0d2c9e97ac00337e4df344b1000956d4e4e8eb11a810cc586a226ad36 [root@localhost docker]# docker ps -all CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 0299abe0d2c9 centos:base "/bin/bash" 12 minutes ago Up 12 minutes 0.0.0.0:80->8080/tcp mytomcat [root@localhost soft]# docker exec -ti mytomcat /bin/bash //进入到mytomcat容器中。 [root@0299abe0d2c9 /]# $PATH //查看环境变量。 bash: /usr/app/jdk/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin: No such file or directory [root@0299abe0d2c9 /]# java -version //查看java版本信息 java version "1.8.0_102" Java(TM) SE Runtime Environment (build 1.8.0_102-b14) Java HotSpot(TM) 64-Bit Server VM (build 25.102-b14, mixed mode) [root@0299abe0d2c9 /]# cd usr/app //创建镜像的时候把相关的文件拷贝到该目录下了。 [root@0299abe0d2c9 app]# ll total 12 drwxr-xr-x. 9 root root 4096 Aug 15 06:23 hadoop drwxr-xr-x. 8 root root 4096 Aug 15 06:23 jdk drwxr-xr-x. 9 root root 4096 Aug 15 06:23 tomcat 将目录切换到tomcat的Bin目录下，运行startup.sh启动tomcat服务即可。 [root@0299abe0d2c9 bin]# ./startup.sh Tomcat started.
