安裝OpenJDK

dnf install java-1.8.0-openjdk* -y

下載和安裝Tomcat 9

wget https://www-eu.apache.org/dist/tomcat/tomcat-9/v9.0.36/bin/apache-tomcat-9.0.36.tar.gz -P /tmp tar -xf /tmp/apache-tomcat-9.0.36.tar.gz -C /usr/local/tomcat/ chown -R root: /usr/local/tomcat/ sh -c 'chmod +x /usr/local/tomcat/apache-tomcat-9.0.36/bin/*.sh'

防火墻開啟端口

firewall-cmd --permanent --zone=public --add-port=8080/tcp
firewall-cmd --reload

將Tomcat設置為作為服務運行

在/etc/systemd/system/目錄中創建tomcat.service文件

vi /etc/systemd/system/tomcat.service

[Unit] Description=Tomcat9 servlet After=syslog.target network.target[Service] Type=forkingUser=root Group=rootEnvironment="JAVA_HOME=/usr/lib/jvm/jre" Environment="JAVA_OPTS=-Djava.awt.headless=true"Environment="CATALINA_BASE=/usr/local/tomcat/apache-tomcat-9.0.36" Environment="CATALINA_HOME=/usr/local/tomcat/apache-tomcat-9.0.36" Environment="CATALINA_PID=/usr/local/tomcat/apache-tomcat-9.0.36/temp/tomcat.pid" Environment="CATALINA_OPTS=-Xms512M -Xmx1024M -server -XX:+UseParallelGC"ExecStart=/usr/local/tomcat/apache-tomcat-9.0.36/bin/startup.sh ExecStop=/usr/local/tomcat/apache-tomcat-9.0.36/bin/shutdown.sh[Install] WantedBy=multi-user.target

chmod 777 /etc/systemd/system/tomcat.service

通知systemd刷新服務

systemctl daemon-reload

開機啟動?tomcat

systemctl enable tomcat

啟動?tomcat

systemctl start tomcat

打開網址

http://192.168.197.103:8080/

這時候打開管理界面manager webapp是訪問不了的，因為只允許本機訪問。需要進行下面設置

/usr/local/tomcat/apache-tomcat-9.0.36/conf/tomcat-users.xml 追加下面內容

<tomcat-users><role rolename="manager"/><role rolename="manager-gui"/><role rolename="manager-script"/> <role rolename="manager-status"/><user username="tomcat" password="tomcat" roles="manager,manager-gui,manager-script,manager-status"/> </tomcat-users>

tomcat為管理界面賬號

默認情況下，Tomcat Web管理界面配置為僅允許從本地主機訪問。

打開 /usr/local/tomcat/apache-tomcat-9.0.36/webapps/manager/META-INF/context.xml 文件并注釋下面內容

<!-- <Valve className="org.apache.catalina.valves.RemoteAddrValve"allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" /> -->

重啟 tomcat

systemctl restart tomcat

之后管理界面可以登錄
