centosjdk_1">1. 基于centos+jdk基础镜像

FROM centos7-jdk-1.0

2. 拷贝源文件到工作目录

• tomcat
  • bin
    • setenv.sh
    • start_tomcat.sh
  • app
    • apache-tomcat-8.5.100.tar.gz
  • conf
    • server.xml

tomcat_14">3. 安装tomcat

3.1 解压安装包

tar -zxvf ${WORK_DIR}/tomcat/app/apache-tomcat-${CATALINA_VERSION}.tar.gz -C ${SRC_SERVER_DIR} && \

3.2 拷贝setenv.sh文件

# 拷贝文件到tomcat安装目录 \
chmod +x ${WORK_DIR}/tomcat/bin/setenv.sh && \
cp ${WORK_DIR}/tomcat/bin/setenv.sh ${SRC_SERVER_DIR}/apache-tomcat-${CATALINA_VERSION}/bin && \

tomcat_25">3.3 拷贝tomcat配置文件

cp -r ${WORK_DIR}/tomcat/conf/* ${SRC_APP_DIR}/tomcat/conf/ && \

3.4 拷贝启动脚本

cp ${WORK_DIR}/tomcat/bin/start_tomcat.sh ${SRC_APP_DIR}/tomcat/bin/ && \
chmod +x ${SRC_APP_DIR}/tomcat/bin/start_tomcat.sh && \

3.5 设置entrypoint命令

## 创建数据、日志目录
## 创建目录
ENV MKDIR_TOMCAT="mkdir -p $SRC_LOG_DIR/tomcat"
## 将SRC拷贝到TARGET目录
ENV COPY_EXPORT="cp -r -t $TGT_DIR $SRC_DIR/*"
## CHMOD
ENV CHOWN_ADMIN="chown -R $SYS_USER_GROUP:$SYS_USER $TGT_DIR $SRC_DIR"
## 启动脚本
ENV START_TOMCAT="su $SYS_USER -c \"$TGT_APP_DIR/tomcat/bin/start_tomcat.sh\""## 进入容器时默认执行的命令
ENTRYPOINT /usr/sbin/sshd && \/usr/sbin/crond && \echo $MKDIR_TOMCAT && $MKDIR_TOMCAT && \echo $COPY_EXPORT && $COPY_EXPORT && \echo $CHOWN_ADMIN && $CHOWN_ADMIN && \echo $START_TOMCAT && $START_TOMCAT && \sleep 9999999d

4. 配置文件示例

4.1 server.xml

一个tomcat内启动多个应用app1和app2

<Service name="app1"><Connector port="8001" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="9001" URIEncoding="UTF-8"maxParameterCount="1000" maxSpareThreads="750" maxThreads="1000" minSpareTHreads="" acceptCount="1000"useBodyEncodingForURI="true"/><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 docBase="/export/App/app1" path="/" reloadable="false"/><Valve className="org.apache.catalina.valves.AccessLogValve" directory="/export/Logs/app1"prefix="access_log" suffix=".log"pattern="%h %l %u %t &quot;%r&quot; %s %b"/></Host></Engine></Service><Service name="app2"><Connector port="8002" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="9002" URIEncoding="UTF-8"maxParameterCount="1000" maxSpareThreads="750" maxThreads="1000" minSpareTHreads="" acceptCount="1000"useBodyEncodingForURI="true"/><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 docBase="/export/App/app2" path="/" reloadable="false"/><Valve className="org.apache.catalina.valves.AccessLogValve" directory="/export/Logs/app2"prefix="access_log" suffix=".log"pattern="%h %l %u %t &quot;%r&quot; %s %b"/></Host></Engine></Service>

4.2 setenv.sh

设置环境变量和Java启动参数

# TOMCAT
export CATALINA_HOME="/export/servers/apache-tomcat-8.5.100"
export CATALINA_BASE="/export/servers/apache-tomcat-8.5.100"
export CATALINA_OUT="/export/Logs/tomcat/catalina.out"
export CATALINA_PID="$CATALINA_BASE/logs/tomcat.pid"# JAVA
export JAVA_HOME="/export/servers/jdk1.8.0_391"
export JAVA_OPTS="-server -Xms5120m -Xmx5120m"

tomcatsh_110">4.3 start_tomcat.sh

tomcat启动脚本，手动指定配置文件位置

#!/bin/bash
CATALINA_HOME="/export/servers/apache-tomcat-8.5.100"
$CATALINA_HOME/bin/startup.sh -config /export/App/tomcat/conf/server.xml &
