Tomcat

Tomcat 服务器是一个免费的开放源代码的Web 应用服务器，属于轻量级应用服务器，在中小型系统和并发访问用户不是很多的场合下被普遍使用，是开发和调试JSP 程序的首选。对于一个初学者来说，可以这样认为，当在一台机器上配置好Apache 服务器，可利用它响应HTML（标准通用标记语言下的一个应用）页面的访问请求。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。

tomcat部署

//关闭selinux和防火墙
[root@localhost ~]# setenforce 0
[root@localhost ~]# sed -ri 's/^(SELINUX=).*/\1disabled/g' /etc/selinux/config
[root@localhost ~]# systemctl disable --now firewalld.service 
 
//安装java
[root@localhost ~]# dnf -y install java-17-openjdk.x86_64
 
//下载tomcat二进制包,并解压
[root@localhost ~]# wget https://dlcdn.apache.org/tomcat/tomcat-10/v10.0.23/bin/apache-tomcat-10.0.23.tar.gz
[root@localhost ~]# tar -xf  apache-tomcat-10.0.23.tar.gz  -C /usr/local
[root@localhost ~]# cd /usr/local/
[root@localhost local]# mv apache-tomcat-10.0.23/ tomcat
[root@localhost local]# cd tomcat/
 
//自定义index.jsp测试网页
[root@localhost tomcat]# mkdir webapps/test
[root@localhost tomcat]# vim webapps/test/index.jsp
<html>
<head>
        <title>test page</title>
</head>
<body>
        <%
                out.println("Hello World");
        %>
</body>
</html>
 
//启动服务

访问测试

配置三个api页面

[root@localhost ~]# vim /usr/local/tomcat/conf/tomcat-users.xml 
<role rolename="admin-gui"/>
<user username="nbr" password="123456" roles="admin-gui"/>
 
[root@localhost ~]# vim /usr/local/tomcat/webapps/host-manager/META-INF/context.xml 
//在allowr那一行增加自己访问的ip网段
 
 <Context antiResourceLocking="false" privileged="true" >
  <CookieProcessor className="org.apache.tomcat.util.http.Rfc6265CookieProcessor"
                   sameSiteCookies="strict" />
  <Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="192\.168\.10\.\d+|150\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />
  <Manager sessionAttributeValueClassNameFilter="java\.lang\.(?:Boolean|Integer|Long|Number|String)|org\.apache\.catalina\.filters\.CsrfPreventionFilter\$LruCache(?:\$1)?|java\.util\.(?:Linked)?HashMap"/>
</Context>
 
//重启服务
[root@localhost ~]# /usr/local/tomcat/bin/catalina.sh stop
[root@localhost ~]# /usr/local/tomcat/bin/catalina.sh start

设置Server Status 和Manager App 页面

[root@localhost ~]# vim /usr/local/tomcat/conf/tomcat-users.xml 
<role rolename="admin-gui"/>
<role rolename="manager-gui"/>
<user username="nbr" password="123456" roles="admin-gui,manager-gui"/>
 
[root@localhost ~]# vim /usr/local/tomcat/webapps/manager/META-INF/context.xml
//在allowr那一行增加自己访问的ip网段
 
<Context antiResourceLocking="false" privileged="true" >
  <CookieProcessor className="org.apache.tomcat.util.http.Rfc6265CookieProcessor"
                   sameSiteCookies="strict" />
  <Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="192\.168\.10\.\d+| 150\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />
  <Manager sessionAttributeValueClassNameFilter="java\.lang\.(?:Boolean|Integer|Long|Number|String)|org\.apache\.catalina\.filters\.CsrfPreventionFilter\$LruCache(?:\$1)?|java\.util\.(?:Linked)?HashMap"/>
</Context>
 
//重启服务
[root@localhost ~]# /usr/local/tomcat/bin/catalina.sh stop
[root@localhost ~]# /usr/local/tomcat/bin/catalina.sh start

编辑service文件

//先关闭服务
[root@localhost ~]# /usr/local/tomcat/bin/catalina.sh stop
 
[root@localhost ~]# vim /usr/lib/systemd/system/tomcat.service
