tomcat服务器的默认端口号是8080
一、只启动一个tomcat的情况
当我们不想使用8080端口，需要修改为其他端口时，我们可以:
1、打开tomcat安装目录下的conf目录，找到server.xml文件。
找到以下代码
代码语言：javascript复制<Connector port="8080" protocol="HTTP/1.1"connectionTimeout="20000"redirectPort="8443" />2、修改端口号
上面的8080就是tomcat的对外访问端口， 我们将他修改为其他端口，但是要避免与系统的端口号冲突，选用一个没有使用过的端口号，然后保存退出 如图将端口号修改为8099
代码语言：javascript复制<Connector port="8099" protocol="HTTP/1.1"connectionTimeout="20000"redirectPort="8443" />3、重启tomcat生效
代码语言：javascript复制[root@localhost tomcat]# netstat -luntp|grep 80tcp6 0 0 127.0.0.1:8005 :::* LISTEN 26201/javatcp6 0 0 :::8009 :::* LISTEN 26201/javatcp6 0 0 :::8080 :::* LISTEN 26201/javatcp6 0 0 :::80 :::* LISTEN 850/httpd[root@localhost tomcat]# ./bin/shutdown.shUsing CATALINA_BASE: /usr/share/tomcatUsing CATALINA_HOME: /usr/share/tomcatUsing CATALINA_TMPDIR: /usr/share/tomcat/tempUsing JRE_HOME: /usr/share/jdkUsing CLASSPATH: /usr/share/tomcat/bin/bootstrap.jar:/usr/share/tomcat/bin/tomcat-juli.jar[root@localhost tomcat]# ./bin/startup.shUsing CATALINA_BASE: /usr/share/tomcatUsing CATALINA_HOME: /usr/share/tomcatUsing CATALINA_TMPDIR: /usr/share/tomcat/tempUsing JRE_HOME: /usr/share/jdkUsing CLASSPATH: /usr/share/tomcat/bin/bootstrap.jar:/usr/share/tomcat/bin/tomcat-juli.jarTomcat started.[root@localhost tomcat]# netstat -luntp|grep 80tcp6 0 0 :::8099 :::* LISTEN 5163/javatcp6 0 0 127.0.0.1:8005 :::* LISTEN 5163/javatcp6 0 0 :::8009 :::* LISTEN 5163/javatcp6 0 0 :::80 :::* LISTEN 850/httpd[root@localhost tomcat]#二、当有多个tomcat时
我们还需修改上面文件的其他两个地方
1、修改Connector port
代码语言：javascript复制116 <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />修改为其他端口，注意避免端口冲突，如下:
代码语言：javascript复制116 <Connector port="18009" protocol="AJP/1.3" redirectPort="8443" />2、修改Server port
代码语言：javascript复制 22 <Server port="8005" shutdown="SHUTDOWN">同样将server port的端口修改为其他端口，注意避免端口冲突，这里我选用18005
代码语言：javascript复制 22 <Server port="18005" shutdown="SHUTDOWN">3、同样重启tomcat
代码语言：javascript复制[root@dlocalhost tomcat]# netstat -luntp|grep 80tcp6 0 0 127.0.0.1:8005 :::* LISTEN 26201/javatcp6 0 0 :::8009 :::* LISTEN 26201/javatcp6 0 0 :::8080 :::* LISTEN 26201/javatcp6 0 0 :::80 :::* LISTEN 850/httpd[root@localhost tomcat]# ./bin/shutdown.shUsing CATALINA_BASE: /usr/share/tomcatUsing CATALINA_HOME: /usr/share/tomcatUsing CATALINA_TMPDIR: /usr/share/tomcat/tempUsing JRE_HOME: /usr/share/jdkUsing CLASSPATH: /usr/share/tomcat/bin/bootstrap.jar:/usr/share/tomcat/bin/tomcat-juli.jar[root@localhost tomcat]# ./bin/startup.shUsing CATALINA_BASE: /usr/share/tomcatUsing CATALINA_HOME: /usr/share/tomcatUsing CATALINA_TMPDIR: /usr/share/tomcat/tempUsing JRE_HOME: /usr/share/jdkUsing CLASSPATH: /usr/share/tomcat/bin/bootstrap.jar:/usr/share/tomcat/bin/tomcat-juli.jarTomcat started.[root@localhost tomcat]# netstat -luntp|grep 80tcp6 0 0 :::18009 :::* LISTEN 7101/javatcp6 0 0 :::8099 :::* LISTEN 5163/javatcp6 0 0 127.0.0.1:8005 :::* LISTEN 5163/javatcp6 0 0 :::8009 :::* LISTEN 5163/javatcp6 0 0 :::80 :::* LISTEN 850/httpdtcp6 0 0 127.0.0.1:18005 :::* LISTEN 7101/java[root@localhost tomcat]#
