#四、Tomcat的管理

# 启动程序 
[root@localhost ~]# /data/application/tomcat/bin/startup.sh

# 关闭程序 
[root@localhost ~]# /data/application/tomcat/bin/shutdown.sh

#####启动停止：

[root@localhost conf]# cd /data/application/tomcat/bin/
[root@localhost bin]# ./startup.sh 
Using CATALINA_BASE:   /data/application/tomcat
Using CATALINA_HOME:   /data/application/tomcat
Using CATALINA_TMPDIR: /data/application/tomcat/temp
Using JRE_HOME:        /usr/local/java
Using CLASSPATH:       /data/application/tomcat/bin/bootstrap.jar:/data/application/tomcat/bin/tomcat-juli.jar
Tomcat started.
[root@localhost bin]# ./shutdown.sh 
Using CATALINA_BASE:   /data/application/tomcat
Using CATALINA_HOME:   /data/application/tomcat
Using CATALINA_TMPDIR: /data/application/tomcat/temp
Using JRE_HOME:        /usr/local/java
Using CLASSPATH:       /data/application/tomcat/bin/bootstrap.jar:/data/application/tomcat/bin/tomcat-juli.jar

注意：tomcat未启动的情况下使用shutdown脚本，会有大量的输出信息。

#####检查tomcat是否启动正常：

[root@localhost ~]# netstat -lntp  |grep java
tcp6       0      0 :::8080                 :::*                    LISTEN      18939/java          
tcp6       0      0 127.0.0.1:8005          :::*                    LISTEN      18939/java          
tcp6       0      0 :::8009                 :::*                    LISTEN      18939/java

#####端口:

• 8005：这个端口负责监听关闭Tomcat的请求 shutdown:向以上端口发送的关闭服务器的命令字符串。
• 8009: 与其他服务通信接口，接受其他服务器转发过来的请求
• 8080: 建立http连接用。可以修改

**说明：**所有与 java 相关的，服务启动都是 java 命名的进程

启动完成后浏览器访问查看

#####查看日志
