Tomcat安装部署

1.官网：http://tomcat.apache.org/

Tomcat服务器是一个免费的开源代码的Web应用服务器，属于轻量级应用服务器，在中小型系统和并发访问用户不是很多的场合下使用，是开发和调试JSP程序的首选。
Tomcat和Nginx、Apache等Web服务器一样，具有处理HTML页面的功能，另外它还是一个Servlet和JSP容器，独立的Servlet容器是Tomcat的默认模式。不过，Tomcat处理静态HTML的能力不如Nginx/Apache服务器。
一般情况下多用Nginx+Tomcat，Nginx处理静态，Tomcat处理动态程序

2.部署Java环境

[root@tomcat ~]# /usr/local/src
[root@tomcat ~]# tar xf jdk-8u241-linux-x64.tar.gz 
[root@tomcat ~]# ln -sv /usr/local/src/jdk1.8.0_241 /usr/local/jdk '/usr/local/jdk' -> '/usr/local/src/jdk1.8.0_241'
 
[root@tomcat ~]# vim /etc/profile 
export JAVA_HOME=/usr/local/jdk 
export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH 
export CLASSPATH=.$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib:$JAVA_HOME/lib/tools.jar
 
 [root@tomcat ~]# source  /etc/profile 
 java -version java version "1.8.0_241" 
 Java(TM) SE Runtime Environment (build 1.8.0_241-b07) 
 Java HotSpot(TM) 64-Bit Server VM (build 25.241-b07, mixed mode

3.部署Tomcat

# 解压软件包
[root@tomcat ~]# tar xf apache-tomcat-9.0.21.tar.gz -C /usr/local/

# 创建一个软链接
[root@tomcat ~]# ln -s /usr/local/apache-tomcat-9.0.21 /usr/local/tomcat

# 定义tomcat所需的环境变量
[root@tomcat ~]# echo "export TOMCAT_HOME=/usr/local/tomcat" >> /etc/profile

# 重新加载环境变量
[root@tomcat ~]# source /etc/profile

Tomcat启动
[root@tomcat ~]# ls /usr/local/tomcat/bin/startup.sh   #启动脚本
/usr/local/tomcat/bin/startup.sh
[root@tomcat ~]# ls /usr/local/tomcat/bin/shutdown.sh   #停止脚本
/usr/local/tomcat/bin/shutdown.sh
 默认方式启动
[root@tomcat ~]# /usr/local/tomcat/bin/startup.sh 
Using CATALINA_BASE:   /usr/local/tomcat
Using CATALINA_HOME:   /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME:        /usr/local/java
Using CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
Tomcat started.

默认方式停止
[root@tomcat ~]# /usr/local/tomcat/bin/shutdown.sh 
Using CATALINA_BASE:   /usr/local/tomcat
Using CATALINA_HOME:   /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME:        /usr/local/java
Using CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar

tomcat启动成功后默认端口为：8080，访问地址http://ip:8080
