docker实现tomcat+jdk+msm

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

[root@1xx tom]#cat kong.sh

#!/bin/bash

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

echo"none key name $I"

dockerstop $I

docker rmi -f $I

echo$keys

done

docker p_w_picpaths

Tomcat 配置

[root@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/memcached-session-manager/wiki/SetupAndConfiguration

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

[root@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 p_w_picpaths

Memcached 配置

[root@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

[root@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

[root@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

验证

Session信息一致说明成功

Service.xml文件内容

[root@1xx tom]# cat server.xml

<?xmlversion='1.0' encoding='utf-8'?>
