docker實作tomcat+jdk+msm

Docker容器

docker版本 : 1.7.1

系統版本：CentOS release 6.8

tomcat版本：apache-tomcat-7.0.57

memcache版本：yum安裝

Docker 容器在運作裡有些步驟出錯會産生<none>之類的無效鏡像，産生之後直接運作腳本

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$keys

done

docker images

[root@1xx tom]#cat Dockerfile

FROM centos #基礎鏡像來自于centos

MAINTAINER xiong <[email protected]> #作者資訊

#安裝ifconfig 類型工具

RUN yum -y install net-tools

#ADD複制本地檔案并自動解壓至目錄下

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

# 運作軟連結指令

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

# 定義tomcat環境變量值

ENV CATALINA_HOME /usr/local/tomcat

ENV PATH $PATH:$CATALINA_HOME/bin

#複制jdk檔案到root目錄并使用rpm指令安裝

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

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

#定義java環境變量

ENV JAVA_HOME=/usr/java/latest

ENV PATH $PATH:$JAVA_HOME/bin

# 當機器運作裡自動啟動，此處可省略

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

# 産先配置好server.xml檔案然後直接複制到conf檔案目錄下

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

# 複制msm檔案至lib檔案下

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

# 運作啟動catalina.sh腳本使用run 腳本在運作之後啟動并列印debug資訊在使用ctrl+p ctrl+q 運作容器，否則腳本運作後之後腳本會退出

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

memcached session manager

https://github.com/magro/memcached-session-manager/wiki/SetupAndConfiguration

下載下傳需要注意版本資訊并且需要注意的是版本号需要對應一緻否則有可能報錯

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 #也可以選擇其它

[root@1xxtom]#cat del.sh

docker rm -f tom{1..9}

docker rm -f mem{1..9}

docker rmi xiong

docker build -t xiong .

[root@1xx memcached]# cat Dockerfile

FROMcentos #基礎鏡像來自于centos

RUN yum -yinstall memcached net-tools #安裝mem以及ifconfig 類型工具

#運作memcached指令，别使用daemon 腳本在運作完之後容器會自動退出

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

[root@1xxmemcached]# cat del.sh

docker rm -f mem1

docker rmi mem

docker build -t mem .

配置完基礎鏡像運作容器，為友善我這裡也定義了腳本

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

# docker 運作容器名稱tom2 端口本地92 容器8080 資料卷本地xx/xx/tom2/ 容器/web/apps 基礎鏡像

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 運作容器名稱m2m1 端口本地201 遠端11211 基礎鏡像

docker run -it--name mem1 -p 201:11211 mem

docker run -it--name mem2 -p 202:11211 mem

docker ps

# 測試容器memcached是否運作成功本地運作telnet

容器tom2号 session資訊

JSESSIONID=A4B7390062C98E719D1CBF5C198F835D-n2

Session資訊一緻說明成功

Service.xml檔案内容

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

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