docker实现tomcat+jdk+msm

gddge11

Docker容器 docker版本      : 1.7.1
系统    版本     ：CentOS release 6.8
tomcat版本    ：apache-tomcat-7.0.57
memcache版本：yum安装

Docker 容器在运行里有些步骤出错会产生<none>之类的无效镜像，产生之后直接运行脚本
删除
[iyunv@1xx tom]#cat kong.sh

#!/bin/bash

#

for I in `docker images | grep"<none>" | awk -F" " '{print $3}'`;do

     echo"none key name $I"

     dockerstop $I

     docker  rmi -f $I

     echo$keys

done

Tomcat 配置[iyunv@1xx tom]#cat Dockerfile

FROM centos                                                   #基础镜像来自于centos

MAINTAINER xiong <812374156@qq.com>  #作者信息

#安装ifconfig 类型工具

RUN yum -y install net-tools                                    

#ADD复制本地文件并自动解压至目录下

ADD apache-tomcat-7.0.57.tar.gz/usr/local/  

# 运行软链接命令

RUN ln -sv /usr/local/apache-tomcat-7.0.57/usr/local/tomcat

# 定义tomcat环境变量值

ENV CATALINA_HOME /usr/local/tomcat

ENV PATH $PATH:$CATALINA_HOME/bin

#复制jdk文件到root目录并使用rpm命令安装

COPY jdk-7u79-linux-x64.rpm /root/

RUN rpm -ivh  /root/jdk-7u79-linux-x64.rpm

#定义java环境变量

ENV JAVA_HOME=/usr/java/latest

ENV PATH $PATH:$JAVA_HOME/bin

# 当机器运行里自动启动，此处可省略

RUN echo"/usr/local/tomcat/catalina.sh start" >> /etc/rc.d/rc.local

# 产先配置好server.xml文件然后直接复制到conf文件目录下

COPY server.xml /usr/local/tomcat/conf/

# 复制msm文件至lib文件下

COPY mem/* /usr/local/tomcat/lib/

# 运行启动catalina.sh脚本使用run 脚本在运行之后启动并打印debug信息在使用ctrl+p ctrl+q 运行容器，否则脚本运行后之后脚本会退出

CMD["catalina.sh","run"]

Msm下载memcached session manager
https://github.com/magro/memcach ... tupAndConfiguration

memcached-session-manager-tc6-${version}.jar for tomcat6,
memcached-session-manager-tc7-${version}.jar for tomcat7
(attention: tomcat 7.0.23+) or memcached-session-manager-tc8-${version}.jar for tomcat8.

下载需要注意版本信息      并且需要注意的是版本号需要对应一致否则有可能报错
javolution-5.4.3.1.jar           
memcached-session-manager-tc7-2.1.1.jar            
spymemcached-2.11.1.jar
memcached-session-manager-2.1.1.jar  
msm-javolution-serializer-2.1.1.jar                        #也可以选择其它

tomcat删除脚本 [iyunv@1xxtom]#cat del.sh

#!/bin/bash

#

docker rm -f tom{1..9}

docker rm -f mem{1..9}

docker rmi xiong

docker build -t xiong .

docker images

Memcached 配置[iyunv@1xx memcached]# cat Dockerfile
         FROMcentos                                                          #基础镜像来自于centos

MAINTAINER xiong812374156@qq.com        #作者信息

RUN yum -yinstall memcached net-tools        #安装mem以及ifconfig 类型工具

         #运行memcached命令，别使用daemon 脚本在运行完之后容器会自动退出

CMD["/usr/bin/memcached","-p","11211","-m","64","-c","1024","-u","root"]

Memcached删除脚本         [iyunv@1xxmemcached]# cat del.sh

#!/bin/bash

#

#

docker rm -f mem1

docker rmi mem

docker build -t mem .

配置完基础镜像运行容器，为方便我这里也定义了脚本
[iyunv@1xx tom]#cat docktest.sh
#!/bin/bash
#
# docker 运行容器名称tom2 端口本地92 容器8080 数据卷本地xx/xx/tom2/ 容器/web/apps 基础镜像
docker run -it--name tom2 -p 92:8080 -v /root/tom/tom2:/web/apps/ xiong
docker run -it--name tom3 -p 93:8080 -v /root/tom/tom3:/web/apps/ xiong

#docker 运行容器名称m2m1 端口本地201 远端11211 基础镜像
docker run -it--name mem1 -p 201:11211 mem
docker run -it--name mem2 -p 202:11211 mem

docker ps


# 测试容器memcached是否运行成功 本地运行telnet


容器tom2号 session信息

JSESSIONID=A4B7390062C98E719D1CBF5C198F835D-n2



JSESSIONID=A4B7390062C98E719D1CBF5C198F835D-n2


验证Session信息一致说明成功


Service.xml文件内容
