//首先关闭selinux和防火墙
[root@localhost ~]# sed -ri 's/^(SELINUX=).*/\1disabled/g' /etc/selinux/config
[root@localhost ~]# setenforce 0
[root@localhost ~]# systemctl disable --now firewalld.service 

//安装jdk，git
[root@localhost ~]# dnf -y install java-11-openjdk git maven sshpass

//下载tomcat9.0.67版本，解压tomcat，并部署安装
[root@localhost ~]# wget https://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-9/v9.0.67/bin/apache-tomcat-9.0.67.tar.gz.
[root@localhost ~]# tar xf apache-tomcat-9.0.67.tar.gz -C /usr/local/
[root@localhost ~]# ln -s /usr/local/apache-tomcat-9.0.67/ /usr/local/tomcat

//编写tomcat.service文件
[root@localhost tomcat]# vim /usr/lib/systemd/system/tomcat.service
[root@localhost tomcat]# cat /usr/lib/systemd/system/tomcat.service
