docker部署TOMCAT项目
一、内核升级
|
[root@test01 ~]# uname -r #内核查看确认 2.6.32-696.16.1.el6.x86_64 [root@test01 ~]# [root@test01 ~]# rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org [root@test01 ~]# rpm -Uvh http://www.elrepo.org/elrepo-release-6-8.el6.elrepo.noarch.rpm #安装yum源 Retrieving http://www.elrepo.org/elrepo-release-6-8.el6.elrepo.noarch.rpm Preparing... ########################################### [100%] 1:elrepo-release ########################################### [100%] [root@test01 ~]# yum --enablerepo=elrepo-kernel install kernel-lt -y 修改grub.conf文件 内核升级完毕后修改内核的启动顺序 vim /etc/grub.conf default=0 |
二、docker 安装
|
安装Yum 源 yum -y install http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm 更新Yum yum update 安装DOCKER yum install docker-io 查看docker版本 docker version 启动 重启 停止 service docker start service docker restart service docker stop |
二、制作Tomcat DOCKER镜像
在tomcat-docker目录下执行命令touch Dockerfile创建一个Dockerfile文件
Vim Dockerfile内容如下，之后保存
|
# 设置继承的镜像 FROM centos:6.8 # 创建者信息 MAINTAINER qin # 设置环境变量，所有操作都是非交互式的 ENV DEBIAN_FRONTEND noninteractive # 设置tomcat的环境变量 ENV CATALINA_HOME /tomcat ENV JAVA_HOME /java # 复制tomcat和jdk文件到镜像中 ADD tomcat /tomcat ADD java /java # 复制启动脚本至镜像，并赋予脚本可执行权限 ADD run.sh /run.sh RUN chmod +x /*.sh RUN chmod +x /tomcat/bin/*.sh # 暴露接口8091，这是我的tomcat接口，默认为8080 EXPOSE 8091 # 设置自启动命令 CMD ["/run.sh"] |
