搭建基础镜像（centos+jdk+tomcat）
- 1. 基于centos+jdk基础镜像
- 2. 拷贝源文件到工作目录
- 3. 安装tomcat
- 3.1 解压安装包
- 3.2 拷贝setenv.sh文件
- 3.3 拷贝tomcat配置文件
- 3.4 拷贝启动脚本
- 3.5 设置entrypoint命令
- 4. 配置文件示例
- 4.1 server.xml
- 4.2 setenv.sh
- 4.3 start_tomcat.sh
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
- bin
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 && \
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 && $START_TOMCAT && \sleep 9999999d
4. 配置文件示例
4.1 server.xml
一个tomcat内启动多个应用app1和app2
<Service name="app1"><Connector port="8001" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="9001" URIEncoding="UTF-8"maxParameterCount="1000" maxSpareThreads="750" maxThreads="1000" minSpareTHreads="" acceptCount="1000"useBodyEncodingForURI="true"/><Engine name="Catalina" defaultHost="localhost"><Realm className="org.apache.catalina.realm.LockOutRealm"><Realm className="org.apache.catalina.realm.UserDatabaseRealm"resourceName="UserDatabase"/></Realm><Host name="localhost" appBase="webapps"unpackWARs="true" autoDeploy="true"><Context docBase="/export/App/app1" path="/" reloadable="false"/><Valve className="org.apache.catalina.valves.AccessLogValve" directory="/export/Logs/app1"prefix="access_log" suffix=".log"pattern="%h %l %u %t "%r" %s %b"/></Host></Engine></Service><Service name="app2"><Connector port="8002" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="9002" URIEncoding="UTF-8"maxParameterCount="1000" maxSpareThreads="750" maxThreads="1000" minSpareTHreads="" acceptCount="1000"useBodyEncodingForURI="true"/><Engine name="Catalina" defaultHost="localhost"><Realm className="org.apache.catalina.realm.LockOutRealm"><Realm className="org.apache.catalina.realm.UserDatabaseRealm"resourceName="UserDatabase"/></Realm><Host name="localhost" appBase="webapps"unpackWARs="true" autoDeploy="true"><Context docBase="/export/App/app2" path="/" reloadable="false"/><Valve className="org.apache.catalina.valves.AccessLogValve" directory="/export/Logs/app2"prefix="access_log" suffix=".log"pattern="%h %l %u %t "%r" %s %b"/></Host></Engine></Service>
4.2 setenv.sh
设置环境变量和Java启动参数
# TOMCAT
export CATALINA_HOME="/export/servers/apache-tomcat-8.5.100"
export CATALINA_BASE="/export/servers/apache-tomcat-8.5.100"
export CATALINA_OUT="/export/Logs/tomcat/catalina.out"
export CATALINA_PID="$CATALINA_BASE/logs/tomcat.pid"# JAVA
export JAVA_HOME="/export/servers/jdk1.8.0_391"
export JAVA_OPTS="-server -Xms5120m -Xmx5120m"
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 &
)
