jdk Tomcat Jenkins

1.Tomcat簡介
Tomcat是Apache軟件基金會（Apache Software Foundation）的Jakarta 項目中的一個核心項目，由Apache、Sun和其他一些公司及個人共同開發而成。
Tomcat服務器是一個免費的開放源代碼的Web應用服務器，屬於輕量級應用服務器，在中小型系統和並發訪問用戶不是很多的場合下被普遍使用，是開發和調試
JSP程序的首選。
Tomcat和Nginx、Apache(httpd)、lighttpd等Web服務器一樣，具有處理HTML頁面的功能，另外它還是一個Servlet和JSP容器，獨立的Servlet容器是
Tomcat的默認模式。不過，Tomcat處理靜態HTML的能力不如Nginx/Apache服務器。

2.Tomcat安裝
2.1軟件準備

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

2.2 部署java和tomcat環境

2.2.1將下載的jdk和tomcat源碼包解壓到/usr/local/include/下
tar -zxvf apache-tomcat-8.0.27.tar.gz -C /usr/local/include/tomcat8 #同理解壓JDK
2.2.2在/etc/profile末尾添加如下代碼，修改完後執行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

3.2 Tomcat配置管理界面（註意：測試功能，生產環境不要用。）

Tomcat管理功能用於對Tomcat自身以及部署在Tomcat上的應用進行管理的web應用。在默認情況下是處於禁用狀態的。如果需要開啟這個功能，就需要配置管理用戶，即配置上面提到的tomcat-users.xml。

配置tomcat-users.xml文件

[root@tomcat01 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

配置完後，重新啟動tomcat服務生效
[root@tomcat ~]# /usr/local/include/tomcat8/bin/shutdown.sh
[root@tomcat ~]# /usr/local/include/tomcat8/bin/startup.sh

配置context.xml文件

[root@tomcat02 conf]# find / -name context.xml
/usr/local/include/tomcat8/webapps/host-manager/META-INF/context.xml #修改訪問IP列表
/usr/local/include/tomcat8/webapps/manager/META-INF/context.xml #修改訪問IP列表
/usr/local/include/tomcat8/conf/context.xml #此處不用修改

修改/usr/local/include/tomcat8/webapps/host-manager/META-INF/context.xml，添加“192.\d+.\d+.\d+”代表可遠程訪問該服務器的IP地址段，192...*（此處註意正則表達式）

[root@tomcat02 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+”代表可遠程訪問該服務器的IP地址段，192...*（此處註意正則表達式）

[root@tomcat02 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>

重新啟動tomcat服務

[root@tomcat02 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
[root@tomcat02 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.

此時可以就可以正常開啟tomcat的Manager App、Host Manager、Server Status等頁面



4.在Tomcat上部署Jenkins系統
4.1將下載好的Jenkins的war包放在/data/www/jenkins/文件夾下面

[root@tomcat02 jenkins]# pwd
/data/www/jenkins
[root@tomcat02 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/目錄下面新建一個名為jenkins.xml的文件。
文件內容如下：
<Context path="jenkins" docBase="/data/www/jenkins/jenkins.war" />

註意：實際上jenkins的war包直接復制到/usr/local/include/tomcat8/webapps/下，就會自動解壓，在webapps目錄下面自動生成jenkins目錄。而且，在發布war包的應用程式時，最好提前停止Tomcat服務。

JDK+Tomcat+Jenkins部署
