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 images | grep"<none>" | awk -F" " '{print $3}'`;do echo"none key name $I" dockerstop $I docker rmi -f $I echo$keysdonedocker images

Tomcat 配置

[root@1xx tom]#cat Dockerfile
FROM centos #基础镜像来自于centosMAINTAINER 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/tomcatENV 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/latestENV 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 xiongdocker build -t xiong .docker images

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 mem1docker rmi memdocker 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
