Linux系统之tomcat的安装方法

一、tomcat介绍

1.tomcat简介

Tomcat是一个开源、免费的Web服务器，属于轻量级web服务器，适合部署中小型、并发访问用户不是很多的web项目，是部署中小型jsp的首选。

2.tomcat官网

tomcat软件官网下载：https://tomcat.apache.org/download-80.cgi

二、本次环境规划

本次环境规划介绍

hostname	IP地址	操作系统版本	tomcat版本	java版本
docker	192.168.3.157	centos 7.6	10.1.7.0	11.0.18

三、安装jdk

1.下载jdk包

下载地址：https://www.oracle.com/java/technologies/downloads/#java11

[root@docker tomcat]# ls
apache-tomcat-10.1.7.tar.gz  jdk-11.0.18_linux-x64_bin.tar.gz

2.安装jdk

解压到jkd软件包

[root@docker tomcat]# ls
apache-tomcat-10.1.7.tar.gz  jdk-11.0.18  jdk-11.0.18_linux-x64_bin.tar.gz

复制二进制文件

[root@docker tomcat]# cp -r /data/tomcat/jdk-11.0.18 /usr/local/jdk/

配置环境变量，在/etc/profile追加以下两行，再激活变量source /etc/profile

export JAVA_HOME=/usr/local/jdk
export PATH=$PATH:$JAVA_HOME/bin

3.检查jdk版本

检查jdk版本

[root@docker tomcat]# java -version
java version "11.0.18" 2023-01-17 LTS
Java(TM) SE Runtime Environment 18.9 (build 11.0.18+9-LTS-195)
Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.18+9-LTS-195, mixed mode)

四、安装tomcat

1.下载tomcat

下载地址：https://dlcdn.apache.org/tomcat/tomcat-10/v10.1.7/bin/

[root@docker tomcat]# ls
apache-tomcat-10.1.7.tar.gz  jdk-11.0.18  jdk-11.0.18_linux-x64_bin.tar.gz

2.解压tomcat软件包

解压tomcat压缩包

[root@docker tomcat]# tar -xzf apache-tomcat-10.1.7.tar.gz  -C /usr/local/
[root@docker tomcat]# mv /usr/local/apache-tomcat-10.1.7/ /usr/local/tomcat

3.设置环境变量

在/etc/profile追加以下两行，再激活变量source /etc/profile

export TOM_HOME=/usr/local/tomcat
export PATH=$PATH:$TOM_HOME/bin

4.查看tomcat版本

查看tomcat版本

[root@docker tomcat]# version.sh 
Using CATALINA_BASE:   /usr/local/tomcat
Using CATALINA_HOME:   /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME:        /usr/local/jdk
Using CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
Using CATALINA_OPTS:   
Server version: Apache Tomcat/10.1.7
Server built:   Feb 27 2023 20:25:27 UTC
Server number:  10.1.7.0
OS Name:        Linux
OS Version:     3.10.0-957.el7.x86_64
Architecture:   amd64
JVM Version:    11.0.18+9-LTS-195
JVM Vendor:     Oracle Corporation

五、启动tomcat

1.启动tomcat服务

启动tomcat服务

[root@docker tomcat]# startup.sh 
Using CATALINA_BASE:   /usr/local/tomcat
Using CATALINA_HOME:   /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME:        /usr/local/jdk
Using CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
Using CATALINA_OPTS:   
Tomcat started.

2.检查tomcat服务状态

检查tomcat服务是否正常启动

[root@docker tomcat]# ps aux |grep tomcat
root     12288  9.8  1.7 5771868 135200 pts/0  Sl   10:57   0:04 /usr/local/jdk/bin/java -Djava.util.logging.config.file=/usr/local/tomcat/conf/logging.properties -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djdk.tls.ephemeralDHKeySize=2048 -Djava.protocol.handler.pkgs=org.apache.catalina.webresources -Dorg.apache.catalina.security.SecurityListener.UMASK=0027 --add-opens=java.base/java.lang=ALL-UNNAMED --add-opens=java.base/java.io=ALL-UNNAMED --add-opens=java.base/java.util=ALL-UNNAMED --add-opens=java.base/java.util.concurrent=ALL-UNNAMED --add-opens=java.rmi/sun.rmi.transport=ALL-UNNAMED -classpath /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar -Dcatalina.base=/usr/local/tomcat -Dcatalina.home=/usr/local/tomcat -Djava.io.tmpdir=/usr/local/tomcat/temp org.apache.catalina.startup.Bootstrap start
root     12331  0.0  0.0 112812   948 pts/0    S+   10:58   0:00 grep --color=auto tomcat

3.访问tomcat的web服务

访问地址：http://192.168.3.157:8080/

4.关闭tomcat服务

直接使用shutdown.sh 关闭tomcat服务

[root@docker tomcat]# ls /usr/local/tomcat/bin/
bootstrap.jar       ciphers.sh                    daemon.sh     migrate.bat       shutdown.sh           tool-wrapper.bat
catalina.bat        commons-daemon.jar            digest.bat    migrate.sh        startup.bat           tool-wrapper.sh
catalina.sh         commons-daemon-native.tar.gz  digest.sh     setclasspath.bat  startup.sh            version.bat
catalina-tasks.xml  configtest.bat                makebase.bat  setclasspath.sh   tomcat-juli.jar       version.sh
ciphers.bat         configtest.sh                 makebase.sh   shutdown.bat      tomcat-native.tar.gz
[root@docker tomcat]# shutdown.sh
