Centos8安装tomcat9以及常见用法

Posted 2023-02-18 晨峰说

1.安装jdk

tomcat9可以工作在jdk8以上的版本

所以可以安装jdk8或是jdk11

dnf install java-11-openjdk # centos8
yum install java-11-openjdk # centos7

2.下载最新的tomcat二进制包

打开网站 https://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-9/

在这里找到最新版本，进入后进入bin目录

里面有名为 apache-tomcat-XXXX.tar.gz 的文件，右键复制地址

下载并解压

wget https://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-9/v9.0.31/bin/apache-tomcat-9.0.31.tar.gz
tar xvf apache-tomcat-9.0.31.tar.gz

移动到安装目录

mv apache-tomcat-9.0.31 /opt/tomcat9

3.常见命令和目录

命令或目录	作用
/opt/tomcat9/bin/startup.sh	启动tomcat
/opt/tomcat9/bin/shutdown.sh	关闭tomcat
/opt/tomcat9/conf/	配置
/opt/tomcat9/logs/	日志
/opt/tomcat9/webapps/	默认应用目录
