JDK+Tomcat+Jenkins部署

Posted 2020-10-30

1.Tomcat简介
    Tomcat是Apache软件基金会（Apache Software Foundation）的Jakarta 项目中的一个核心项目，由Apache、Sun和其他一些公司及个人共同开发而成。
    Tomcat服务器是一个免费的开放源代码的Web应用服务器，属于轻量级应用服务器，在中小型系统和并发访问用户不是很多的场合下被普遍使用，是开发和调试
JSP程序的首选。
    Tomcat和nginx、Apache(httpd)、lighttpd等Web服务器一样，具有处理html页面的功能，另外它还是一个Servlet和JSP容器，独立的Servlet容器是
Tomcat的默认模式。不过，Tomcat处理静态HTML的能力不如Nginx/Apache服务器。
  
2.Tomcat安装
    2.1软件准备

            JDK下载：http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
            Tomcat下载：http://tomcat.apache.org/
            Jenkins下载：https://jenkins.io/index.html

    2.2 部署java和tomcat环境

                2.2.1将下载的jdk和tomcat源码包解压到/usr/local/include/下
                        tar -zxvf apache-tomcat-8.0.27.tar.gz -C /usr/local/include/tomcat8     #同理解压JDK
                2.2.2在/etc/profile末尾添加如下代码，修改完后执行source /etc/profile，使配置文件立即生效
                        export JAVA_HOME=/usr/local/include/jdk/
                        export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH
                        export TOMCAT_HOME=/usr/local/include/tomcat8/
                        export CLASSPATH=$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib:$JAVA_HOME/lib/tools.jar
    2.3 Tomcat目录介绍

                        .
                        ├── bin         #→用以启动、关闭Tomcat或者其它功能的脚本（.bat文件和.sh文件）
                        ├── conf        #→用以配置Tomcat的XML及DTD文件
                        ├── lib         #→存放web应用能访问的JAR包

                        └── work        #→用以产生有JSP编译出的Servlet的.java和.class文件
                        7 directories, 4 files
    2.4 webapps目录结构
                        [[email protected] tomcat]# cd webapps/
                        [[email protected] webapps]# ll
                        total 20
                        drwxr-xr-x 14 root root 4096 Oct  5 12:09 docs     #→tomcat帮助文档

    2.5 启动Tomcat（也可直接使用/usr/local/include/tomcat8/bin/catalina.sh start|stop）

        启动程序: /usr/local/include/tomcat8/bin/startup.sh
        关闭程序: /usr/local/include/tomcat8/bin/shutdown.sh

                        [[email protected] ~]# /application/tomcat/bin/startup.sh
                        Using CATALINA_BASE:   /application/tomcat

3.Tomcat配置文件
    3.1 Tomcat配置文件介绍

            [[email protected] tomcat8]# ll /usr/local/include/tomcat8/conf/
            total 228
            drwxr-x--- 3 root root   4096 Apr 22 15:00 Catalina
            -rwxr-xr-x 1 root root  12895 Apr 13 20:58 catalina.policy
            -rwxr-xr-x 1 root root   7376 Apr 13 20:58 catalina.properties
            -rwxr-xr-x 1 root root   1338 Apr 22 21:41 context.xml
            -rwxr-xr-x 1 root root   1149 Apr 13 20:58 jaspic-providers.xml
            -rwxr-xr-x 1 root root   2358 Apr 13 20:58 jaspic-providers.xsd
            -rwxr-xr-x 1 root root   3622 Apr 13 20:58 logging.properties
            -rwxr-xr-x 1 root root   7509 Apr 22 15:05 server.xml               #→主配置文件
            -rwxr-xr-x 1 root root   2298 Apr 22 22:10 tomcat-users.xml         #→Tomcat管理用户配置文件
            -rwxr-xr-x 1 root root   2633 Apr 13 20:58 tomcat-users.xsd
            -rwxr-xr-x 1 root root 168133 Apr 13 20:58 web.xml
 
    3.2 Tomcat配置管理界面（注意：测试功能，生产环境不要用。）
    
            Tomcat管理功能用于对Tomcat自身以及部署在Tomcat上的应用进行管理的web应用。在默认情况下是处于禁用状态的。如果需要开启这个功能，就需要配置管理用户，即配置上面提到的tomcat-users.xml。

            配置tomcat-users.xml文件
 
            [[email protected] tomcat8]# vim /usr/local/include/tomcat8/conf/tomcat-users.xml
            …………
            <role rolename="admin-gui"/>
            <role rolename="manager-gui"/>
            <role rolename="manager-status"/>
            <role rolename="manager-script"/>
            <role rolename="manager-jmx"/>
            <user username="tomcatadmin" password="Foxconn99" roles="admin-gui,manager-gui,manager-status,manager-script,manager-jmx" />
            </tomcat-users>  #在此行前加入上面六行

                配置完后，重新启动tomcat服务生效
                [[email protected] ~]# /usr/local/include/tomcat8/bin/shutdown.sh
                [[email protected] ~]# /usr/local/include/tomcat8/bin/startup.sh

            配置context.xml文件

                [[email protected] conf]# find / -name context.xml
                /usr/local/include/tomcat8/webapps/host-manager/META-INF/context.xml    #修改访问IP列表
                /usr/local/include/tomcat8/webapps/manager/META-INF/context.xml         #修改访问IP列表
                /usr/local/include/tomcat8/conf/context.xml     #此处不用修改
 
             修改/usr/local/include/tomcat8/webapps/host-manager/META-INF/context.xml，添加“192.\d+.\d+.\d+”代表可远程访问该服务器的IP地址段，192...*（此处注意正则表达式）
 
                [[email protected] conf]# vim /usr/local/include/tomcat8/webapps/host-manager/META-INF/context.xml
                <?xml version="1.0" encoding="UTF-8"?>
                <Context antiResourceLocking="false" privileged="true" >
                <Valve className="org.apache.catalina.valves.RemoteAddrValve"
                             allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1|192\.\d+\.\d+\.\d+" />
                </Context>
 
            修改/usr/local/include/tomcat8/webapps/host-manager/META-INF/context.xml，添加“192.\d+.\d+.\d+”代表可远程访问该服务器的IP地址段，192...*（此处注意正则表达式）

                [[email protected] conf]# vim /usr/local/include/tomcat8/webapps/manager/META-INF/context.xml
                <?xml version="1.0" encoding="UTF-8"?>
                <Context antiResourceLocking="false" privileged="true" >
                <Valve className="org.apache.catalina.valves.RemoteAddrValve"
                             allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1|192\.\d+\.\d+\.\d+" />
                </Context>
 
            重新启动tomcat服务

                [[email protected] conf]# /usr/local/include/tomcat8/bin/catalina.sh stop
                Using CATALINA_BASE:   /usr/local/include/tomcat8
                Using CATALINA_HOME:   /usr/local/include/tomcat8
                Using CATALINA_TMPDIR: /usr/local/include/tomcat8/temp
                Using JRE_HOME:        /usr/local/include/jdk/
                Using CLASSPATH:       /usr/local/include/tomcat8/bin/bootstrap.jar:/usr/local/include/tomcat8/bin/tomcat-juli.jar
                [[email protected] conf]# /usr/local/include/tomcat8/bin/catalina.sh start
                Using CATALINA_BASE:   /usr/local/include/tomcat8
                Using CATALINA_HOME:   /usr/local/include/tomcat8
                Using CATALINA_TMPDIR: /usr/local/include/tomcat8/temp
                Using JRE_HOME:        /usr/local/include/jdk/
                Using CLASSPATH:       /usr/local/include/tomcat8/bin/bootstrap.jar:/usr/local/include/tomcat8/bin/tomcat-juli.jar
                Tomcat started.

        此时可以就可以正常开启tomcat的Manager App、Host Manager、Server Status等页面



4.在Tomcat上部署Jenkins系统
    4.1将下载好的Jenkins的war包放在/data/www/jenkins/文件夹下面

                    [[email protected] jenkins]# pwd
                    /data/www/jenkins
                    [[email protected] jenkins]# ll
                    total 67064
                    -rwxrwxrwx 1 root root 68669812 Apr 11 21:32 jenkins.war

    4.2在/usr/local/include/tomcat8/conf/Catalina/localhost/目录下面新建一个名为jenkins.xml的文件。
           文件内容如下：
                                <Context path="jenkins" docBase="/data/www/jenkins/jenkins.war" />
 
            注意：实际上jenkins的war包直接复制到/usr/local/include/tomcat8/webapps/下，就会自动解压，在webapps目录下面自动生成jenkins目录。而且，在发布war包的应用程式时，最好提前停止Tomcat服务。
