阿里云服务器结合域名解析部署springboot项目到Tomcat

一、环境准备

1.SpringBoot项目改造

1.1 pom.xml文件

1.1.1 为了保证配置后不影响本地项目的启动，我们需要去除打包后的war包的内嵌tomcat。

<dependency>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-web</artifactId>
		<exclusions>
			<exclusion>
				<groupId>org.springframework.boot</groupId>
				<artifactId>spring-boot-starter-tomcat</artifactId>
			</exclusion>
		</exclusions>
</dependency>
<dependency>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-tomcat</artifactId>
		<scope>provided</scope>
</dependency>

1.1.2 启动类也需要改造。下面是示例：

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
import org.springframework.web.WebApplicationInitializer;

@SpringBootApplication
public class DemoApplication extends SpringBootServletInitializer implements WebApplicationInitializer {
	@Override
	protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
		return application.sources(DemoApplication.class);
	}


	public static void main(String[] args) {
		SpringApplication.run(DemoApplication.class, args);
	}

}

2. Tomcat配置

2.1 下载

首先去Tomcat官网下载Tomcat，这里采用Tomcat8.5.57。

2.2 配置

2.2.1 修改tomcat目录下的conf文件夹下的server.xml文件。

1.2.1.1 找到

 <Connector port="8080" protocol="HTTP/1.1"
  			connectionTimeout="20000"
  			redirectPort="8443" />

将“8080”修改为“80”，如下：

 <Connector port="80" protocol="HTTP/1.1"
            connectionTimeout="20000"
            redirectPort="8443" />

2.2.1.2 找到

 <Host name="localhost"  appBase="webapps"
            unpackWARs="true" autoDeploy="true">
        <!-- 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 &quot;%r&quot; %s %b" />
      </Host>

将Host标签的name属性修改为自己的域名，我这里是“www.jmuyuer.com”,并添加标签（注意：我这里的docBase使用的是相对路径，也就是war包解压后的项目名）。

 <Host name="www.jmuyuer.com"  appBase="webapps"
            unpackWARs="true" autoDeploy="true">
            
        <Context path="" docBase="demo" reloadable="true" crossContext="true"/>

        <!-- 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 &quot;%r&quot; %s %b" />

      </Host>

2.3 启动

2.3.1 进入到Tomcat目录下的bin文件夹，输入以下命令启动。

sudo ./startup.sh

输入以下命令关闭。

sudo ./shutdown.sh
