Centos7安裝設定tomcat9

 sudo yum update

之後在關閉內建firewalled (如以後外部防火牆設備)等設定及yum vim..等相關套件工具

安裝java1.8 相關套件

yum install -y java-1.8.0-openjdk java-1.8.0-openjdk-devel

確認JAVA版本是否為1.8

java -version

cd /tmp

Tomcat 的官方網站下載最新的 Tomcat 9 壓縮檔(這邊是安裝tomcat9.0.50)

wget https://downloads.apache.org/tomcat/tomcat-9/v9.0.50/bin/apache-tomcat-9.0.50.zip

同時下載 SHA512 的檢查碼

wget https://downloads.apache.org/tomcat/tomcat-9/v9.0.50/bin/apache-tomcat-9.0.50.zip.sha512

驗證sha512sum 檢查一下檔案比對兩邊檢查碼是否一樣

sha512sum apache-tomcat-9.0.50.zip

cat apache-tomcat-9.0.50.zip.sha512

解壓縮tomcat並把解開移至opt/tomcat

unzip apache-tomcat-9.0.50.zip

mv apache-tomcat-9.0.50 /opt/tomcat

建立tomcat帳號

useradd -r tomcat --shell /bin/false

設定tomcat資料夾權限

cd /opt/tomcat

sudo chgrp -R tomcat *

sudo chmod g+rwx conf

sudo chmod -R g+r conf

sudo chown -R tomcat webapps/ work/ temp/ logs/

sudo chmod +x /opt/tomcat/bin/*.sh

設定 Systemd 啟動指令檔

vim /etc/systemd/system/tomcat.service

=======================================================

[Unit]

Description=Apache Tomcat 9

After=syslog.target network.target

[Service]

User=tomcat

Group=tomcat

Type=forking

Environment=CATALINA_PID=/opt/tomcat/temp/tomcat.pid

Environment=CATALINA_HOME=/opt/tomcat

Environment=CATALINA_BASE=/opt/tomcat

ExecStart=/opt/tomcat/bin/startup.sh

ExecStop=/opt/tomcat/bin/shutdown.sh

Restart=on-failure

Environment='CATALINA_OPTS=-Xms512M -Xmx8192M -server -XX:+UseParallelGC'

Environment='JAVA_OPTS=-Djava.awt.headless=true -Djava.security.egd=file:/dev/./urandom'

[Install]

WantedBy=multi-user.target

=======================================================

重新載入 Systemd

systemctl daemon-reload

啟動 Tomcat 服務並設定自動開機啟動tomcat

systemctl enable tomcat

systemctl start tomcat

查看 Tomcat 服務的狀態

systemctl status tomcat

開起網頁 http://serverIP:8080/ 

新增Tomcat管理者的帳號 (這裡如設定username admin  password admin)

vim /opt/tomcat/conf/tomcat-users.xml

在「</tomcat-users>」之前新增下列設定

======================================================

<role rolename="admin-gui" />

<user username="admin" password="admin" roles="manager-gui,admin-gui" />

======================================================

再來設定允許本機以外的IP可以連線管理網頁

vim /opt/tomcat/webapps/manager/META-INF/context.xml

進去看到後下列設定參數刪除 即可開放任何IP連線管理者網頁

<Valve className="org.apache.catalina.valves.RemoteAddrValve"

allow="127.d+.d+.d+|::1|0:0:0:0:0:0:0:1" />

跳出重啟服務

systemctl restart tomcat

驗證管理者帳號是否有效

點選「Server Status」

彈出敲帳密視窗把剛剛設號帳密打進去結果如下:

PS:也可做個測試頁在webapps底下建個test資料夾建立test.jsp

cd /opt/tomcat/webapps/

mkdir test 進去test資料夾

vim test.jsp

======================

test tomcat ok!

======================

重啟tomcat服務

systemctl restart tomcat

進去tomcat網頁

http://serverIP:8080/ test/test.jsp  出現剛剛編寫測試成功網頁
