Tomcat基礎
1、安裝jdk
1.1 安裝jdk
[root@master1 tomcat]# ls
apache-tomcat-8.0.41.tar.gz jdk-8u121-linux-x64.rpm
安裝jdk
[root@master1 tomcat]# rpm -ivh jdk-8u121-linux-x64.rpm1.2 設置java環境變量
[root@master1 jdk1.8.0_121]# vim /etc/profile.d/java.sh export JAVA_HOME=/usr/java/latest export PATH=$JAVA_HOME/bin:$PATH [root@master1 jdk1.8.0_121]# . /etc/profile.d/java.sh [root@master1 jdk1.8.0_121]# echo $PATH /usr/java/latest/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin [root@master1 jdk1.8.0_121]#
1.3 顯示java版本版本號
[root@master1 jdk1.8.0_121]# java -version
java version "1.8.0_121"
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)2、安裝tomcat
2.1 解壓tomcat
[root@master1 tomcat]# tar xf apache-tomcat-8.0.41.tar.gz -C /usr/local/2.2 創建軟連接
[root@master1 local]# ln -sv apache-tomcat-8.0.41 tomcat
‘tomcat’ -> ‘apache-tomcat-8.0.41’
[root@master1 local]# ll
total 0
drwxr-xr-x 9 root root 149 Jan 16 22:47 apache-tomcat-8.0.41
lrwxrwxrwx 1 root root 20 Jan 16 22:49 tomcat -> apache-tomcat-8.0.41
[root@master1 local]# 2.3 設置tomcat目錄
[root@master1 tomcat]# vim /etc/profile.d/tomcat.sh export CATALINA_HOME=/usr/local/tomcat export PATH=$CATALINA_HOME/bin:$PATH 重載環境變量： [root@master1 tomcat]# . /etc/profile.d/tomcat.sh [root@master1 tomcat]# echo $PATH /usr/local/tomcat/bin:/usr/java/latest/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin [root@master1 tomcat]# 顯示tomcat版本號： [root@master1 tomcat]# version.sh Using CATALINA_BASE: /usr/local/tomcat Using CATALINA_HOME: /usr/local/tomcat Using CATALINA_TMPDIR: /usr/local/tomcat/temp Using JRE_HOME: /usr/java/latest Using CLASSPATH: /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar Server version: Apache Tomcat/8.0.41 Server built: Jan 18 2017 22:19:39 UTC Server number: 8.0.41.0 OS Name: Linux OS Version: 3.10.0-327.el7.x86_64 Architecture: amd64 JVM Version: 1.8.0_121-b13 JVM Vendor: Oracle Corporation [root@master1 tomcat]# 由於所有腳本集中在catalina.sh，可以通過在catalina傳遞腳本參數，調用其他shell [root@master1 tomcat]# catalina.sh version Using CATALINA_BASE: /usr/local/tomcat Using CATALINA_HOME: /usr/local/tomcat Using CATALINA_TMPDIR: /usr/local/tomcat/temp Using JRE_HOME: /usr/java/latest Using CLASSPATH: /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar Server version: Apache Tomcat/8.0.41 Server built: Jan 18 2017 22:19:39 UTC Server number: 8.0.41.0 OS Name: Linux OS Version: 3.10.0-327.el7.x86_64 Architecture: amd64 JVM Version: 1.8.0_121-b13 JVM Vendor: Oracle Corporation [root@master1 tomcat]#
2.4 啟動tomcat並查看默認是否監聽8080端口
[root@master1 tomcat]# catalina.sh start
Using CATALINA_BASE: /usr/local/tomcat
Using CATALINA_HOME: /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME: /usr/java/latest
Using CLASSPATH: /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
Tomcat started.
[root@master1 tomcat]#
[root@master1 tomcat]# ss -tnlp | grep 80
LISTEN 0 100 :::8009 :::* users:(("java",pid=23581,fd=52))
LISTEN 0 100 :::8080 :::* users:(("java",pid=23581,fd=47))
[root@node1 ~]# curl -I http://10.201.106.131:8080

[root@node1 ~]# 手動添加一個測試應用程序
1、創建webapp特有的目錄結構
[root@master1 webapps]# mkdir myapp/{lib,classes,WEB-INF,META-INF} -pv
mkdir: created directory ‘myapp’
mkdir: created directory ‘myapp/lib’
mkdir: created directory ‘myapp/classes’
mkdir: created directory ‘myapp/WEB-INF’
mkdir: created directory ‘myapp/META-INF’
[root@master1 webapps]# tree myapp/
myapp/
├── classes
├── lib
├── META-INF
└── WEB-INF
4 directories, 0 files
[root@master1 webapps]# 1.1 制作測試頁
[root@master1 webapps]# vim myapp/index.jsp
<%@ page language="java" %>
<%@ page import="java.util.*" %>
<html>
<head>
<title>JSP Test Page</title>
</head>
<body>
<% out.println("Hello,world."); %>
</body>
</html>
訪問測試：
[root@node1 ~]# curl http://10.201.106.131:8080/myapp/index.jsp
<html>
<head>
<title>JSP Test Page</title>
</head>
<body>
Hello,world.
</body>
</html>
[root@master1 tomcat]# tree work

[root@master1 tomcat]# 3、創建用戶訪問tomcat的管理程序
[root@master1 conf]# pwd
/usr/local/tomcat/conf
[root@master1 conf]# vim tomcat-users.xml
<role rolename="manager-gui"/>
<user username="tomcat" password="tomcat" roles="manager-gui"/>
重啟服務，間隔操作：5秒：
[root@master1 conf]# catalina.sh stop
Using CATALINA_BASE: /usr/local/tomcat
Using CATALINA_HOME: /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME: /usr/java/latest
Using CLASSPATH: /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
[root@master1 conf]# catalina.sh start
Using CATALINA_BASE: /usr/local/tomcat
Using CATALINA_HOME: /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME: /usr/java/latest
Using CLASSPATH: /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
Tomcat started.
[root@master1 conf]# 4、創建訪問圖片界面【Host Manager】的賬戶
/usr/local/tomcat/conf
[root@master1 conf]# vim tomcat-users.xml
<role rolename="admin-gui"/>
<user username="tomcat" password="tomcat" roles="manager-gui,admin-gui"/>
重啟tomcat
[root@master1 bin]# catalina.sh stop
Using CATALINA_BASE: /usr/local/tomcat
Using CATALINA_HOME: /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME: /usr/java/latest
Using CLASSPATH: /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
[root@master1 bin]# catalina.sh start
Using CATALINA_BASE: /usr/local/tomcat
Using CATALINA_HOME: /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME: /usr/java/latest
Using CLASSPATH: /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
Tomcat started.
[root@master1 bin]# 5、配置server.xml
5.1 備份server.xml
5.2 通過8005端口關閉虛擬機實例
通過8005端口關閉虛擬機實例：
[root@master1 ~]# ss -tnl
