Tomcat及LAMT架构搭建

Tomcat介绍

Tomcat 服务器是一个免费的开放源代码的Web 应用服务器,是开发和调试JSP 程序的首选。

实际上Tomcat是Apache 服务器的扩展，但运行时它是独立运行的，所以当你运行tomcat 时，它实际上作为一个与Apache 独立的进程单独运行的.

配置LAMT

实验环境

系统	主机IP	服务
CenOS8	192.168.197.147	HTTP Mysql Tomcat

部署Tomcat

配置JAVA环境(JDK)

# 安装JDK环境
[root@localhost ~]# yum install -y java-1.8.0-openjdk*
......
Complete!

下载解压tomcat

[root@localhost src]# wget https://archive.apache.org/dist/tomcat/tomcat-10/v10.0.0-M10/bin/apache-tomcat-10.0.0-M10.tar.gz
--2020-11-26 10:27:49--  https://archive.apache.org/dist/tomcat/tomcat-10/v10.0.0-M10/bin/apache-tomcat-10.0.0-M10.tar.gz

[root@localhost src]# tar xf apache-tomcat-10.0.0-M10.tar.gz -C /usr/local
[root@localhost src]# cd /usr/local
[root@localhost local]# ls
apache-tomcat-10.0.0-M10  bin  etc  games  include  lib  lib64  libexec  sbin  share  src

# 创建软链接
[root@localhost local]# ln -s apache-tomcat-10.0.0-M10/ tomcat

[root@localhost local]# cd tomcat/
[root@localhost tomcat]# ls
bin           conf             lib      logs    README.md      RUNNING.txt  webapps
BUILDING.txt  CONTRIBUTING.md  LICENSE  NOTICE  RELEASE-NOTES  temp         work

创建index.jsp文件

[root@localhost tomcat]# cd webapps/
[root@localhost webapps]# ls
docs  examples  host-manager  manager  ROOT
[root@localhost webapps]# touch test
[root@localhost webapps]# vim index.jsp

<html>
<head> 
        <title>test page</title>
</head> 
<body>  
         <%      
                out.println("Hellow World");
         %>     
</body>
</html>

开启tomcat服务

[root@localhost webapps]# /usr/local/tomcat/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
Using CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
Using CATALINA_OPTS:   
Tomcat started.
[root@localhost webapps]# ss -antl
State       Recv-Q      Send-Q                Local Address:Port            Peer Address:Port      
LISTEN      0           128                         0.0.0.0:22                   0.0.0.0:*

访问tomcat主页
访问test目录内容
主页上Server status,Manager App,Host Manager 出现403拒绝访问
解决方案

[root@localhost webapps]# vim usr/local/tomcat/conf/tomcat-users.xml
......
<role rolename="manager-gui"/>
<role rolename="admin-gui"/>
<user username="tomcat" password="123456" roles="admin-gui,manager-gui"/>
</tomcat-users>

    ##文件尾部添加角色名及用户密码


##  在manager/context文件中添加本机ip
[root@localhost manager]# vim META-INF/context.xml 
......
<Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="192\.168\.197\.\d+|127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />     ## 在allow中添加本网段地址
         
         
         
##  同理，添加host-manager配置文件中Ip
[root@localhost local]# vim tomcat/webapps/host-manager/META-INF/context.xml
......
  <Valve className="org.apache.catalina.valves.RemoteAddrValve"
          allow="192\.168\.197\.\d+|127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />
......

## 重启服务
[root@localhost local]# /usr/local/tomcat/bin/catalina.sh stop;/usr/local/tomcat/bin/catalina.sh start
......
Tomcat started.

配置虚拟主机文件

[root@localhost httpd24]# vim /etc/httpd24/httpd.conf
# 末尾处添加
......
<VirtualHost *:80>
    DocumentRoot "/usr/local/httpd/htdocs"
    ProxyPass / http://192.168.197.147:8080/
    ProxyPassReverse / http://192.168.197.147:8080/
    <Directory "/usr/local/httpd/htdocs">
        Options none
        AllowOverride none
        Require all granted
    </Directory>
</VirtualHost>

直接访问80端口，web会跳转到8080端口
