引言:
Tomcat是常见的免费的web服务器,前端服务很多都是通过tomcat部署的!所以多了解点肯定没坏处!
一、配置端口
1.防火墙策略中配置8888端口,并允许策略:

二、安装tomcat包
1.新建tomcat文件夹
进入 /usr/local,并新建文件夹
![]()
mkdir 文件夹名字 
2.将apache-tomcat-8.5.82.tar.gz上传到新建文件夹下

你可以拖拽也可以通过 cp apache-tomcat-8.5.82.tar.gz 指定文件夹
3.解压tar.gz包

4.cd 进入tomcat的conf文件夹下的server.xml

5.将默认的8080端口服务改为8888端口:
<!-- A "Connector" represents an endpoint by which requests are received
         and responses are returned. Documentation at :
         Java HTTP Connector: /docs/config/http.html
         Java AJP  Connector: /docs/config/ajp.html
         APR (HTTP/AJP) Connector: /docs/apr.html
         Define a non-SSL/TLS HTTP/1.1 Connector on port 8080
    -->
    <Connector port="8888" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />
    <!-- A "Connector" using the shared thread pool-->
    <!--
    <Connector executor="tomcatThreadPool"
               port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />
    -->
    <!-- Define an SSL/TLS HTTP/1.1 Connector on port 8443
         This connector uses the NIO implementation. The default
         SSLImplementation will depend on the presence of the APR/native
         library and the useOpenSSL attribute of the AprLifecycleListener.
         Either JSSE or OpenSSL style configuration may be used regardless of
         the SSLImplementation selected. JSSE style configuration is used below.
    --> 
如果是配置https服务:在8443 里面 需要换端口的话换,不换的话默认,里面引入ssl证书 !
三、启动tomcat服务
因为前面我们介绍过JDK环境的配置,我们就不需要再去管java版本和jdk已经环境变量是都配置成功了,不清楚的可以查看这篇文章:linux服务器中JDK的安装和配置_尔嵘的博客-CSDN博客。
1.进入bin
cd bin 
2.关闭tomcat 服务
./shutdown.sh 
3.启动tomcat服务
./startup.sh 
也有用以下命令启动:
catalina run 

四、启动效果:
默认你的tomcat启动之后,浏览器就可以访问你指定的端口了,效果如下:

五、其他相关(防火墙相关,端口)
1.启动防火墙
systemctl start firewalld 
 2.查看防火墙状态 
 
systemctl status firewalld 
 3.开放80和8888端口:
 
firewall-cmd --zone=public --add-port=80/tcp --permanent
firewall-cmd --zone=public --add-port=8888/tcp --permanent 
4.效果如下,真是服务器效果:
