Tomcat

Tomcat基础

1、安装jdk

1.1 安装jdk

[root@master1 tomcat]# ls
apache-tomcat-8.0.41.tar.gz  jdk-8u121-linux-x64.rpm

安装jdk
[root@master1 tomcat]# rpm -ivh jdk-8u121-linux-x64.rpm

1.2 设置java环境变量

[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 显示java版本版本号

[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、安装tomcat

2.1 解压tomcat

[root@master1 tomcat]# tar xf apache-tomcat-8.0.41.tar.gz -C /usr/local/

2.2 创建软连接

[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 设置tomcat目录

[root@master1 tomcat]# vim /etc/profile.d/tomcat.sh

export CATALINA_HOME=/usr/local/tomcat
export PATH=$CATALINA_HOME/bin:$PATH

重载环境变量：
[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]# 

显示tomcat版本号：
[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]# 

由于所有脚本集中在catalina.sh，可以通过在catalina传递脚本参数，调用其他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 启动tomcat并查看默认是否监听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
HTTP/1.1 200 OK
Server: Apache-Coyote/1.1
Content-Type: text/html;charset=UTF-8
Transfer-Encoding: chunked
Date: Mon, 16 Jan 2017 15:17:12 GMT

[root@node1 ~]#

手动添加一个测试应用程序

1、创建webapp特有的目录结构

[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 制作测试页

    [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>

访问测试：
[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
work
└── Catalina
    └── localhost
        ├── docs
        ├── examples
        ├── host-manager
        ├── manager

        │               └── index_jsp.java
        └── ROOT
            └── org
                └── apache
                    └── jsp
                        ├── index_jsp.class
                        └── index_jsp.java

19 directories, 6 files
[root@master1 tomcat]#

3、创建用户访问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"/>

重启服务，间隔操作：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、创建访问图片界面【Host Manager】的账户

/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"/>

重启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 备份server.xml

5.2 通过8005端口关闭虚拟机实例

通过8005端口关闭虚拟机实例：
[root@master1 ~]# ss -tnl
State       Recv-Q Send-Q Local Address:Port               Peer Address:Port

LISTEN      0      1      ::ffff:127.0.0.1:8005                     :::*                  
[root@master1 ~]# 
[root@master1 ~]# 
[root@master1 ~]# 
[root@master1 ~]# telnet 127.0.0.1 8005
