tomcat

#: 安装jdk

[root@localhost ~]# yum install jdk-8u211-linux-x64.rpm -y

#:导入环境变量

[root@localhost java]# vim /etc/profile.d/jdk.sh
export JAVA_HOME=/usr/java/default
export PATH=$JAVA_HOME/bin:$PATH
[root@localhost java]# . /etc/profile.d/jdk.sh 
[root@localhost java]# . /etc/profile.d/jdk.sh 

#: 安装tomcat

[root@localhost ~]# tar xf apache-tomcat-8.5.42.tar.gz -C /usr/local/
[root@localhost ~]# cd /usr/local/
[root@localhost local]# ln -sv apache-tomcat-8.5.42/ tomcat

#:创建Java用户

[root@localhost tomcat]# useradd -r java

#: 修改属主属组

[root@localhost tomcat]# chown -R java.java ./*

#: 启动服务


[root@localhost tomcat]# su - java -c "/usr/local/tomcat/bin/catalina.sh start"

 

 

 

 

#: 修改默认页

[root@localhost tomcat]# vim  /usr/local/tomcat/conf/web.xml

    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
        <welcome-file>index.html</welcome-file>
        <welcome-file>index.htm</welcome-file>
    </welcome-file-list>


#:在ROOT目录下添加一个test.jsp,然后访问


[root@localhost ROOT]# vim test.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>jsp例子</title>
</head>
<body>
后面的内容是服务器端动态生成字符串,最后拼接在一起
<%
out.println("hello jsp");
%>
%</body>
%</html>
%

#:然后通过网页访问,访问后在此目录下会有转换后的文件

[root@localhost tomcat]# cd work/Catalina/localhost/ROOT/org/apache/jsp/
[root@localhost jsp]# ll
total 68
-rw-r----- 1 java java 18182 Jun  5 04:31 index_jsp.class
-rw-r----- 1 java java 30078 Jun  5 04:31 index_jsp.java
-rw-r----- 1 java java  5644 Sep  2 10:16 test_jsp.class
-rw-r----- 1 java java  5004 Sep  2 10:16 test_jsp.java

#:部署一个应用,跟ROOT目录同级

[root@localhost webapps]# mkdir myapp/{WEB-INF,class,lib} -pv
[root@localhost webapps]# cp ROOT/test.jsp myapp/index.jsp

#:在此访问

http://192.168.5.101:8080/myapp/

#: 修改管理接口的SHUTDOWN命令

[root@localhost tomcat]# vim conf/server.xml

<Server port="8005" shutdown="slkfjlsjflksjdglksvv">

 

#:用户认证

[root@localhost tomcat]# vim conf/tomcat-users.xml 
<role rolename="manager-gui"/>
<user username="tomcat" password="maxuebin" roles="manager-gui"/>

[root@localhost tomcat]# vim webapps/manager/META-INF/context.xml
 allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1|192.168.*" />


[root@localhost tomcat]# su - tomcat -c "bin/startup.sh" 

 

#:虚拟机配置

尝试再配置一个虚拟主机,并将myapp部署到/data/webapps目录下

[root@localhost ~]# mkdir /data/webapps -pv
[root@localhost ~]# cp /usr/local/tomcat/webapps/myapp/index.jsp /data/webapps/ROOT/
[root@localhost ~]# vim /usr/local/tomcat/conf/server.xml 
      <Host name="www.magedu.net"  appBase="/data/webapps/">
      </Host>

#:在物理机hosts解析,访问测试

http:
//www.magedu.net:8080

#:contex配置

[root@localhost conf]# vim server.xml
    <Context path="/test" docBase="/data/test" reloadable="" /> #:reloadabletrue表示如果WEB-INF/classesMETA-INF/lib目录下.class文件有改动,就会将WEB应用重新加载。     生成环境中,会使用false来禁用。
[root@localhost webapps]# mv ROOT/index.jsp test/
[root@localhost webapps]# ln -sv test/ tests #:注意:这里特别使用了软链接,原因就是以后版本升级,需要将软链接指向myappv2,重启Tomcat。如果新版上       线后,出现问题,重新修改软链接到上一个版本的目录,并重启,就可以实现回滚

 


#:访问测试

http://www.magedu.net:8080/tests/

 

 

#: tomcat和nginx结合

[root@localhost webapps]# vim /etc/nginx/nginx.conf
        location / {
                proxy_pass http://127.0.0.1:8080;
        }


#:实现动静分离
[root@localhost webapps]# vim /etc/nginx/nginx.conf

        location / {
                root /data/webapps/ROOT;
                index index.html;
        }
        location ~* \.jsp {
                proxy_pass http://127.0.0.1:8080;
        }

[root@localhost ROOT]# cd /data/webapps/ROOT/
[root@localhost ROOT]# vim index.html
this is html
[root@localhost ROOT]# cp ../test/index.jsp ./

#:分别测试

 

#:host-manager配置

[root@localhost tomcat]# vim conf/tomcat-users.xml
<role rolename="admin-gui"/>
<user username="tom" password="centos" roles="admin-gui"/>

[root@localhost tomcat]# su - tomcat -c "/usr/local/tomcat/bin/shutdown.sh"
[root@localhost tomcat]# su - tomcat -c "/usr/local/tomcat/bin/startup.sh"

 

 

 

# httpd和tomcat结合

[root@localhost ~]# httpd -M |grep proxy

# 注释中心主机

[root@localhost conf.d]# vim /etc/httpd/conf/httpd.conf 
#DocumentRoot "/var/www/html"

#:创建虚拟主机

[root@localhost conf.d]# vim virthost.conf 
<VirtualHost *:80>
ServerName      node1.magedu.com
ProxyRequests   Off
ProxyVia        On
ProxyPreserveHost On
ProxyPass       / http://127.0.0.1:8080/
ProxyPassReverse / http://127.0.0.1:8080/
</VirtualHost>

ProxyRequests:Off关闭正向代理。
ProxyPass:反向代理指令
ProxyPassReverse:保留代理的response头不重写(个别除外) ProxyPreserveHost:On开启。让代理保留原请求的Host首部


#:测试



#:proxy_ajp_module模块代理配置

[root@localhost conf.d]# vim virthost.conf
<VirtualHost *:80>
ServerName      node1.magedu.com
ProxyRequests   Off
ProxyVia        On
ProxyPreserveHost On
ProxyPass       / ajp://127.0.0.1:8009/
</VirtualHost>
