linux下安装tomcat

tomcat官网https://tomcat.apache.org/，选择下载tomcat 8，如下。

tomcat的使用需要jdk环境，一般的linx安装后会自带jdk，所以这一步不用操作。

[root@CentOS7-1 bin]# java -version
openjdk version "1.8.0_161"
OpenJDK Runtime Environment (build 1.8.0_161-b14)
OpenJDK 64-Bit Server VM (build 25.161-b14, mixed mode)

将下载好的安装包apache-tomcat-8.5.77.tar.gz上传到linux的/tools目录下，并解压到/usr/local目录下

[root@CentOS7-1 ~]# tar zxf /tools/apache-tomcat-8.5.77.tar.gz -C /usr/local/
[root@CentOS7-1 ~]# cd /usr/local/
[root@CentOS7-1 local]# ls
[root@CentOS7-1 local]# ls apache-tomcat-8.5.77

tomcat安装路径为usr/local/apache-tomcat-8.5.77，bin/为tomcat相关操作命令目录，conf/为配置文件目录(server.xml)，logs/为日志目录

启动tomcat并配置环境变量

[root@CentOS7-1 local]# cd apache-tomcat-8.5.77/bin/
[root@CentOS7-1 bin]# ./startup.sh 
Using CATALINA_BASE:   /usr/local/apache-tomcat-8.5.77
Using CATALINA_HOME:   /usr/local/apache-tomcat-8.5.77
Using CATALINA_TMPDIR: /usr/local/apache-tomcat-8.5.77/temp
Using JRE_HOME:        /usr
Using CLASSPATH:       /usr/local/apache-tomcat-8.5.77/bin/bootstrap.jar:/usr/local/apache-tomcat-8.5.77/bin/tomcat-juli.jar
Using CATALINA_OPTS:   
Tomcat started.
[root@CentOS7-1 apache-tomcat-8.5.77]# echo "export PATH=$PATH:/usr/local/apache-tomcat-8.5.77/bin/">>/etc/profile
[root@CentOS7-1 apache-tomcat-8.5.77]# source /etc/profile

在浏览器界面输入虚机ip:8080，会跳转到tomcat服务界面。

同时也查看tomcat日志

[root@CentOS7-1 apache-tomcat-8.5.77]# cd logs/
[root@CentOS7-1 logs]# ls
catalina.2022-03-20.log  host-manager.2022-03-20.log  localhost_access_log.2022-03-20.txt
catalina.out             localhost.2022-03-20.log     manager.2022-03-20.log
[root@CentOS7-1 logs]# more catalina.out
