CentOS7安装与配置Tomcat9。0。39

　　查询tomcat是否安装[root@VM-0-10-centos /]# rpm -q tomcat package tomcat is not installedwget下载安装包
　　现在https://tomcat.apache.org/download-90.cgi官网找到apache-tomcat-9.0.39.tar.gz安装包的路径：https://mirror.bit.edu.cn/apache/tomcat/tomcat-9/v9.0.39/bin/apache-tomcat-9.0.39.tar.gz
　　然后通过命令安装即可，如下[root@VM-0-10-centos server]# wget https://mirror.bit.edu.cn/apache/tomcat/tomcat-9/v9.0.39/bin/apache-tomcat-9.0.39.tar.gz --2020-11-14 20:17:10--  https://mirror.bit.edu.cn/apache/tomcat/tomcat-9/v9.0.39/bin/apache-tomcat-9.0.39.tar.gz Resolving mirror.bit.edu.cn (mirror.bit.edu.cn)... 219.143.204.117, 202.204.80.77, 2001:da8:204:1205::22 Connecting to mirror.bit.edu.cn (mirror.bit.edu.cn)|219.143.204.117|:443... connected.

　　进入tomcat目录/bin，然后./startup.sh[root@VM-0-10-centos bin]# ./startup.sh Using CATALINA_BASE:   /opt/java/server/apache-tomcat-9.0.39 Using CATALINA_HOME:   /opt/java/server/apache-tomcat-9.0.39 Using CATALINA_TMPDIR: /opt/java/server/apache-tomcat-9.0.39/temp Using JRE_HOME:        /usr Using CLASSPATH:       /opt/java/server/apache-tomcat-9.0.39/bin/bootstrap.jar:/opt/java/server/apache-tomcat-9.0.39/bin/tomcat-juli.jar Using CATALINA_OPTS:    Tomcat started. 成功访问 ？
　　居然访问成功了，查看了一下防火墙[root@VM-0-10-centos bin]# clear [root@VM-0-10-centos bin]# firewall-cmd --state  not running
　　默认安装的系统没有打开防火墙，我们手动开一下。systemctl start firewalld.service[root@VM-0-10-centos bin]# firewall-cmd --state  running
　　防火墙打开了，我们刷新刚才的页面是打不开的。
　　开启8080端口:
　　永久添加指定需要开放的端口：[root@VM-0-10-centos bin]#  firewall-cmd --zone=public --add-port=8080/tcp --permanent success
　　重载入添加的端口：[root@VM-0-10-centos bin]#  firewall-cmd --reload success
　　查询指定端口是否开启成功：[root@VM-0-10-centos bin]# firewall-cmd --query-port=8080/tcp yes
　　现在可以正常访问Tomcat了
