使用Dockerfile搭建NGINX+TOMCAT

NGINX

1、nginx.conf裏主要配置信息

        location /xiaofei{
            root html;
            index  index.html index.htm;
            proxy_pass     http://lnmp_tomcat:8080/xiaofei;
            proxy_set_header   Host    $host;
            proxy_set_header   Remote_Addr    $remote_addr;
            proxy_set_header   X-Real-IP    $remote_addr;
            proxy_set_header   X-Forwarded-For    $proxy_add_x_forwarded_for;

        }

2、Dockerfile內容

FROM docker.io/centos
LABEL "auth"="Uncle.joker" \
      "mail"="[email protected]"
ENV TIME_ZOME Asia/Shanghai
RUN yum install -y gcc gcc-c++ make openssl-devel prce-devel
ADD nginx-1.14.2.tar.gz /opt/
RUN cd /opt/nginx-1.14.2 && \
    ./configure --prefix=/usr/local/nginx && \
    make -j 4 && \
    make install

RUN rm -rf /opt/nginx* && \
    yum clean all && \
    echo "${TIME_ZOME}" > /etc/timezone && \
    ln -sf /usr/share/zoneinfo/${TIME_ZOME} /etc/localtime

COPY nginx.conf /usr/local/nginx/conf/
WORKDIR /usr/local/nginx/
EXPOSE 80
CMD ["./sbin/nginx","-g","daemon off;"]

3、Duild鏡像

# cd /root/dockerfile/nginx && docker build -t mytomcat/nginx:1.5 .

4、啓動鏡像

# docker run -itd --name nginx1 --network lnmp -p 8888:80 mytomcat/nginx:1.5

TOMCAT

1、目錄結構如下

[root@ecs-5704-0004 tomcat]# tree ./
./
├── apache-tomcat-7.0.92.tar.gz
├── catalina.sh
├── Dockerfile
├── jdk-7u80-linux-x64.tar.gz
└── server.xml

2、配置文件內容
（1）、server.xml

<?xml version='1.0' encoding='utf-8'?>
<Server port="8005" shutdown="SHUTDOWN">
  <Listener className="org.apache.catalina.startup.VersionLoggerListener" />
  <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />
  <Listener className="org.apache.catalina.core.JasperListener" />
  <Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener" />
  <Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" />
  <Listener className="org.apache.catalina.core.ThreadLocalLeakPreventionListener" />

  <GlobalNamingResources>

    <Resource name="UserDatabase" auth="Container"
              type="org.apache.catalina.UserDatabase"
              description="User database that can be updated and saved"
              factory="org.apache.catalina.users.MemoryUserDatabaseFactory"
              pathname="conf/tomcat-users.xml" />
  </GlobalNamingResources>

  <Service name="Catalina">

    <Connector port="8080" protocol="HTTP/1.1"
                connectionTimeout="20000"
                redirectPort="8443"
                maxThreads="2000"
                minSpareThreads="25"
                acceptCount="2000"
                disableUploadTimeout="true"
                enableLookups="false"
                useBodyEncodingForURI="true"
                URIEncoding="UTF-8" />
    <Connector port="8009"
               protocol="AJP/1.3"
               connectionTimeout="20000"
               redirectPort="8443"
               maxThreads="2000"
               minSpareThreads="25"
               acceptCount="2000"
               disableUploadTimeout="true"
               enableLookups="false"
               URIEncoding="UTF-8" />

    <Engine name="Catalina" defaultHost="localhost">

      <Realm className="org.apache.catalina.realm.LockOutRealm">

        <Realm className="org.apache.catalina.realm.UserDatabaseRealm"
               resourceName="UserDatabase"/>
      </Realm>

      <Host name="localhost"  appBase="webapps"
            unpackWARs="true" autoDeploy="true">
                 <Context path="/xiaofei" docBase="/data/apps/fireway" crossContext="true" reloadable="false"/>

        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="localhost_access_log." suffix=".txt"
               pattern="%h %l %u %t &quot;%r&quot; %s %b" />

      </Host>
    </Engine>
  </Service>
</Server>

（2）、catalina.sh配置內容如下
主要是在啓動腳本的內容下增加了內存等信息的調優。

JAVA_OPTS="-server -Xms6G -Xmx6G  -Xmn2248M -XX:PermSize=384M -XX:MaxPermSize=700M -Xss256K -XX:+DisableExplicitGC -XX:SurvivorRa

3、Dockerfile裏的內容

FROM docker.io/centos
LABEL "auth"="Uncle.Joker" \
      "mail"="[email protected]"

ENV TIME_ZOME Asia/Shanghai

#--config JDK.1.7
ADD jdk-7u80-linux-x64.tar.gz /opt/
ENV JAVA_HOME /opt/jdk1.7.0_80
ENV PATH ${JAVA_HOME}/bin:${PATH}

#--config TOMCAT 7
ADD apache-tomcat-7.0.92.tar.gz /usr/local/
RUN mv /usr/local/apache-tomcat-7.0.92 /usr/local/tomcat
COPY server.xml /usr/local/tomcat/conf/
COPY catalina.sh /usr/local/tomcat/bin/
RUN chmod +x /usr/local/tomcat/bin/catalina.sh
WORKDIR /usr/local/tomcat
EXPOSE 8080
CMD ["./bin/catalina.sh","run"]

4、Build鏡像

# /root/dockerfile/tomcat && docker build -t mytomcat:7.0.92_latest .

5、啓動鏡像

# docker run -itd --name lnmp_tomcat --network lnmp  -v /root/dockerfile/app/tomcat/:/data/apps/fireway mytomcat:7.0.92_latest
