2020.4.2 CentOS7配置Tomcat8

1. 安装jdk
   下载jdk8
   拷贝到服务器后解压安装到/usr/路径下即可

tar -zxvf jdk-8u241-linux-x64.tar.gz

2. 配置jdk环境变量
   在/etc/profile文件中，配置环境变量，是JDK在所有用户中生效：

	vim /etc/profile
　　export JAVA_HOME=/usr/jdk1.8.0_241
　　export JRE_HOME=$JAVA_HOME/jre
　　export CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib
　　export PATH=$JAVA_HOME/bin:$PATH

使修改的环境变量生效

source /etc/profile

3. 安装tomcat 8
   download
   将文件上传到服务器，我选择安装在/etc/tomcat8目录下

tar -zxvf apache-tomcat-8.5.53.tar
mv apache-tomcat-8.5.53/ tomcat8

4. 启动tomcat测试

/etc/tomcat8/bin/startup.sh
输出信息
Using CATALINA_BASE:   /etc/tomcat8
Using CATALINA_HOME:   /etc/tomcat8
Using CATALINA_TMPDIR: /etc/tomcat8/temp
Using JRE_HOME:        /usr/jdk1.8.0_241/jre
Using CLASSPATH:       /etc/tomcat8/bin/bootstrap.jar:/etc/tomcat8/bin/tomcat-juli.jar
Tomcat started.

查看是否监听8080端口

netstat -nplt | percol
tcp        0      0 0.0.0.0:8080            0.0.0.0:*               LISTEN      31192/java

打开localhost:8080查看是否启动成功

5. 关闭tomcat
   执行shutdown.sh脚本即可

/etc/tomcat8/bin/shutdown.sh
输出信息
Using CATALINA_BASE:   /etc/tomcat8
Using CATALINA_HOME:   /etc/tomcat8
Using CATALINA_TMPDIR: /etc/tomcat8/temp
Using JRE_HOME:        /usr/jdk1.8.0_241/jre
Using CLASSPATH:       /etc/tomcat8/bin/bootstrap.jar:/etc/tomcat8/bin/tomcat-juli.jar
