Web——安装httpd服务(Tomcat)及Nginx+Tomcat负载均衡
·
1.Tomcat介绍
(1)tomcat简介
Tomcat是Apache软件基金会Jakarta项目的核心产品，是一个开源的轻量级Web应用服务器。它支持最新的Servlet和JSP规范，主要用于开发和调试Java Web应用。
Tomcat可以独立运行，也能与Apache等Web服务器配合使用。它主要处理JSP页面和Servlet请求，同时也能响应HTML页面，但在处理静态HTML方面性能不如专门的Web服务器。
作为免费、稳定且技术先进的服务器，Tomcat在中小型系统和开发环境中被广泛使用，是Java Web开发的首选服务器之一。
(2)web服务对比
以下是常见的Java Web应用服务器对比：
性能高，但商业收费
Resin服务器
- 由Caucho公司开发，支持Servlet和JSP
- 性能非常快，包含内置HTML Web服务器
- 既能显示动态内容，也能高效处理静态内容
- 许多网站使用Resin构建
Jetty服务器
- 纯Java实现的网页服务器和Servlet容器
- 通常用于计算机间通信，常作为大型软件框架的一部分
- Eclipse基金会下的自由开源项目
JBoss服务器
- 符合JavaEE规范的开源纯Java EJB服务器
- 对J2EE有良好支持，核心服务提供EJB服务器
- 不包含Servlet和JSP的Web容器，但可与Tomcat完美结合
WebSphere服务器
- IBM公司的产品系列，包括WebSphere Application Server等
- 基于Java的应用环境，支持多种操作系统平台
- 用于建立、部署和管理Internet/Intranet Web应用程序
WebLogic服务器
- BEA公司的产品系列，包括WebLogic Server等
- 功能强大，支持企业级、多层次和完全分布式的Web应用
- 配置简单、界面友好，是寻求完整Java平台功能用户的理想选择
性价比高，开源免费
Tomcat服务器
- Apache软件基金会的开源项目
- 轻量级Servlet容器，实现Java Servlet和JSP规范
- 配置简单，资源占用少，社区活跃
- 适合中小型项目和开发测试环境
(3)三大web服务对比(apache、nginx、tomcat)
| 特性 | Apache | Nginx | Tomcat |
|---|---|---|---|
| 主要用途 | 通用Web服务器 | 高性能Web服务器/反向代理 | Java Servlet容器 |
| 处理模型 | 多进程/多线程（MPM） | 事件驱动、异步非阻塞 | 多线程（Java线程池） |
| 性能 | 中等，连接数多时资源消耗大 | 高，适合高并发、静态资源 | 中等，主要用于动态Java应用 |
| 配置 | .htaccess、httpd.conf | nginx.conf（简洁） | server.xml、web.xml |
| 扩展性 | 模块丰富（mod_php、mod_ssl等） | 模块化，但需编译或动态加载 | 通过Servlet/JSP扩展 |
| 适用场景 | PHP网站、传统LAMP架构 | 静态文件、反向代理、负载均衡 | Java Web应用（JSP/Servlet） |
| 许可证 | Apache 2.0 | BSD | Apache 2.0 |
简洁总结：
- Apache：稳定、模块丰富，适合传统动态网站（如PHP）。
- Nginx：高性能、低内存，适合高并发静态服务和反向代理。
- Tomcat：专为Java Web应用设计，是Servlet/JSP容器，常与Nginx搭配（Nginx处理静态，Tomcat处理动态Java）。
2.Tomcat的安装和配置
1）环境准备
(1)IP规划
Tomcat服务器的ip为：192.168.30.126
(2)服务器版本
(3)关闭防火墙
systemctl stop firewalld
systemctl disable firewalld
(4)关闭Selinux
setenforce 0
vim /etc/selinux/config
SELINUX=disabled
selinux改完重启后生效(init 0 / reboot)
(5)安装aliyun、epel、remi源(可选)
yum repolist
# 下载Aliyun源
curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
# 下载阿Epel源
curl -o /etc/yum.repos.d/epel.repo https://mirrors.aliyun.com/repo/epel-7.repo
#下载Remi源(可选)
yum install -y http://rpms.remirepo.net/enterprise/remi-release-7.rpm
(6)创建存放目录并存放软件包
软件包下载地址
https://download.csdn.net/download/qq_44769717/92969448
创建存放软件包目录
mkdir -pv /usr/local/src/tomcat_jdk
存放软件包
2）安装tomcat
(1)解压tomcat和jdk8
tar -xvzf apache-tomcat-9.0.48.tar.gz -C /usr/local/
tar -xvzf jdk-8u261-linux-x64.tar.gz -C /usr/local/
mv apache-tomcat-9.0.48/ /usr/local/tomcat
mv jdk1.8.0_261/ /usr/local/jdk
(2)配置jdk的环境
配置 Java 环境变量
vim /etc/profile
export JAVA_HOME=/你的路径/ jdk1.8.0_261
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH
(3)刷新配置文件
source /etc/profile
java -version
(4)启动tomcat
# cd /你的tomcat路径/bin
cd /usr/local/tomcat/bin
chmod +x *.sh
bash startup.sh
注意
看到输出 Tomcat started.，说明启动指令已发送
(5)验证
netstat -anpt | grep 8080
tail -f ../logs/catalina.out
(6)页面访问
访问
# 你的ip:8080
192.168.30.126:8080
注意：
如果你的tomcat端口号和别的服务冲突了，请修改端口号
find / -name server.xml
找到server.xml这个文件进行编辑
找到修改 Connector 进行修改
修改 Connector 端口
修改完之后要进行重启
./shutdown.sh
./startup.sh
(7)配置服务启动脚本(推荐方式二)
1.服务脚本centos6、7通用
vim /etc/init.d/tomcat
#!/bin/bash
#chkconfig: 35 86 89
#description: Apache Tomcat version 9.0 web applications and web services.
TOMCATBIN=/usr/local/tomcat/bin/catalina.sh
export JAVA_HOME=/usr/local/java
start(){
$TOMCATBIN start
}
stop(){
$TOMCATBIN stop
}
restart(){
stop
start
}
status(){
if [ -f '/var/run/tomcat.pid' ];then
echo 'tomcat is running'
else
echo 'tomcat is not run'
fi
}
configtest(){
$TOMCATBIN configtest
}
case "$1" in
start)
start;;
stop)
stop;;
restart)
restart;;
status)
status;;
configtest)
configtest;;
*)
echo '{start|stop|restart|configtest|status}'
esac
添加权限
chmod +x /etc/init.d/tomcat
chkconfig --add tomcat
chkconfig tomcat on
service tomcat start
2.systemctl服务脚本centos7适用(本文使用，推荐使用)
cat > /etc/systemd/system/tomcat.service << 'EOF'
[Unit]
Description=Apache Tomcat Web Application Container
After=network.target
[Service]
Type=forking
Environment="JAVA_HOME=/usr/local/jdk"
Environment="CATALINA_HOME=/usr/local/tomcat"
Environment="CATALINA_PID=/usr/local/tomcat/temp/tomcat.pid"
Environment="CATALINA_OPTS=-Xms512M -Xmx1024M -server -XX:+UseParallelGC"
ExecStart=/usr/local/tomcat/bin/startup.sh
ExecStop=/usr/local/tomcat/bin/shutdown.sh
User=root
Group=root
RestartSec=10
Restart=always
[Install]
WantedBy=multi-user.target
EOF
注意
1.Environment=“JAVA_HOME=/usr/local/jdk” 后面的路径是解压安装后jdk的路径
2.Environment="CATALINA_HOME=/usr/local/tomcat"后面的路径是解压安装后tomcat的路径
重载进程使其生效
# 添加执行权限
chmod +x /etc/systemd/system/tomcat.service
# 重载进程
systemctl daemon-reload
相关命令
# 启动tomcat
systemctl start tomcat
# 开机自启tomcat
systemctl enabled tomcat
# 停止tomcat
systemctl stop tomcat
# 重启tomcat
systemctl restart tomcat
# 查看tomcat的状态
systemctl status tomcat
(8)基于域名虚拟web主机
1.配置域名
vim /etc/hosts
192.168.30.126 www.lmx.com
2.创建站点目录
mkdir -pv /web/webapp
3.编辑java网页
创建index.jsp默认首页
cat > /web/webapp/index.jsp << 'EOF'
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<html>
<head>
<title>java web page</title>
</head>
<body>
<% out.println("welcom to test site,tomcat");%>
</body>
</html>
EOF
cat /web/webapp/index.jsp
创建test.jsp测试页面
cat > /web/webapp/test.jsp << 'EOF'
<html>
<head><title>Hello World</title>
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
</head>
<body>
Hello World!<br/>
<%
out.println("Your IP address is " + request.getRemoteAddr());
%>
</body>
</html>
EOF
cat /web/webapp/test.jsp
创建test1.jsp测试页面
cat > /web/webapp/test1.jsp << 'EOF'
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%! int fontSize; %>
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>冷莫溪</title>
</head>
<body>
<h3>For 循环实例</h3>
<%for ( fontSize = 1; fontSize <= 3; fontSize++){ %>
<font color="green" size="<%= fontSize %>">
冷莫溪
</font><br />
<%}%>
</body>
EOF
cat /web/webapp/test1.jsp
4.配置tomcat
编辑tomcat主配置文件server.xml文件
vim /usr/local/tomcat/conf/server.xml
在原本的Host name=”localhost”里添加
<Context docBase="/web/webapp" path="" reloadable="false"></Context>
在复制一个，修改name为自己的域名
<Host name="www.lmx.com" appBase="webapps"
unpackWARs="true" autoDeploy="true">
<Context docBase="/web/webapp" path="" reloadable="false"></Context>
<!-- SingleSignOn valve, share authentication between web applications
Documentation at: /docs/config/valve.html -->
<!--
<Valve className="org.apache.catalina.authenticator.SingleSignOn" />
-->
<!-- Access log processes all example.
Documentation at: /docs/config/valve.html
Note: The pattern used is equivalent to using pattern="common" -->
<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
prefix="localhost_access_log" suffix=".txt"
pattern="%h %l %u %t "%r" %s %b" />
</Host>
整体配置如下

注意：
是对标签，成对出现的
5.重启tomcat
systemctl restart tomcat
6.修改Hosts文件
修改服务器hosts文件
vim /etc/hosts
192.168.30.126 www.lmx.com
修改客户机hosts文件
以管理员方式打开记事本，在C:\Windows\System32\drivers\etc中打开hosts
添加后保存
192.168.30.126 www.lmx.com
7.本机访问域名
www.lmx.com:8080
www.lmx.com:8080/test.jsp
www.lmx.com:8080/test1.jsp
3）Tomcat目录说明
|---bin：存放启动和关闭tomcat脚本；
|---configtest.sh： 检测配置文件
|---startup.sh：启动tomcat
|---shutdown.sh：关闭tomcat
|---conf：存放Tomcat服务器的各种全局配置⽂文件，其中最重要的是server.xml和web.xml；
|---server.xml： tomcat的主配置文件 host配置
|---web.xml： tomcat的应用程序的部署描述符文件
|---lib：存放Tomcat服务器所需的各种jar文件；
|---logs：存放Tomcat执行时的日志文件；
|---temp：此目录是tomcat存放的临时文件；
|---webapps：tomcat默认存放应用程序的目录，好比apache的默认网页存放路径
是/var/www/html一样；
|---docs： tomcat文档
|---examples： tomcat自带的一个独立的web应用程序例子
|---host-manager： tomcat的主机管理应用程序
|---manager： tomcat的管理应用程序
|---ROOT： 指tomcat的应用程序的根，如果应用程序部署在ROOT中，则可直接通过http://i
p:port 访问到
|---work：用于存放JSP应用程序在部署时编译后产生的class文件
3. Nginx负载均衡实现
(1)环境规划
以下是本次部署的环境规划表：
| 主机 | IP地址 | 主要软件 |
|---|---|---|
| LNMP服务器 | 192.168.30.125 | nginx-1.16.1 mysql-5.7.32-el7-x86_64 php-7.3.9 |
| Tomcat服务器 1 | 192.168.30.126 | apache-tomcat-9.0.48 jdk-8u261-linux-x64 |
| Tomcat服务器 2 | 192.168.30.127 | apache-tomcat-9.0.48 jdk-8u261-linux-x64 |
| 客户端（用于测试） | 192.168.30.253 |
环境说明：
- LNMP服务器：运行Nginx作为反向代理和负载均衡器，同时部署MySQL和PHP服务，使用的是以往做的基于CentOS7.9——LNMP
- Tomcat服务器 1 & 2：两台应用服务器，运行相同的Tomcat和JDK版本，用于部署Java Web应用
- 网络规划：所有服务器位于同一网段（192.168.30.0/24），便于内部通信
(2)Nginx负载均衡的实现
1）Tomcat站点访问内容差异化修改
为了测试效果，对两台tomcat的站点访问的内容进行差异化修改
tomcat 1（192.168.30.126）
cat > /web/webapp/test.jsp << 'EOF'
<html>
<head><title>Hello World</title>
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
</head>
<body>
Hello 我是tomcat 1 1 1 1 1<br/>
<%
out.println("Your IP address is " + request.getRemoteAddr());
%>
</body>
</html>
EOF
cat /web/webapp/test.jsp
tomcat 2（192.168.30.127）
cat > /web/webapp/test.jsp << 'EOF'
<html>
<head><title>Hello World</title>
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
</head>
<body>
Hello 我是tomcat 2 2 2 2 2<br/>
<%
out.println("Your IP address is " + request.getRemoteAddr());
%>
</body>
</html>
EOF
cat /web/webapp/test.jsp
2）配置hosts文件
tomcat 1（192.168.30.126）
192.168.30.126 www.lmx.com
tomcat 2（192.168.30.127）
192.168.30.127 www.lmx2.com
tomcat 2（192.168.30.125）
192.168.30.126 www.lmx.com
192.168.30.127 www.lmx2.com
客户端（192.168.30.253）
以管理员方式打开记事本，在C:\Windows\System32\drivers\etc中打开hosts
添加并保存
192.168.30.126 www.lmx.com
192.168.30.127 www.lmx2.com
3）Nginx负载均衡的实现
1.添加负载均衡的服务器列表
在lnmp服务器的Nginx配置文件中，添加设定负载均衡的服务器列表（在server块上面）
upstream tomcat_server {
server 192.168.30.126:8080 weight=1;
server 192.168.30.127:8080 weight=1;
}
在server块里面添加以jsp文件为后缀名的匹配请求的配置块
location ~ \.jsp$ {
proxy_pass http://tomcat_server;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
配置说明：
proxy_pass http://tomcat_server;：将匹配到的请求转发给名为tomcat_server的上游服务器组（Upstream）。proxy_set_header Host $host;：告诉后端 Tomcat，“我是代表哪个域名来访问你的”。proxy_set_header X-Real-IP $remote_addr;：$remote_addr是 Nginx 获取到的直接连接者的 IP（即用户的公网 IP），将其放入X-Real-IP请求头传给 Tomcat。proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;：X-Forwarded-For(XFF) 是一个标准协议头，用于记录请求经过的所有代理服务器 IP。$proxy_add_x_forwarded_for变量会将“客户端真实 IP”追加到现有的 XFF 列表后面。
