這篇文章主要介紹了Java應用服務器之tomcat部署,本文通過實例圖文相結合給大家介紹的非常詳細，對大家的學習或工作具有一定的參考借鑒價值，需要的朋友可以參考下
一、相關術語簡介
首先我們來了解下tomcat是什么，tomcat是apache軟件基金會中的一個項目，由apache、Sun 和其他一些公司及個人共同開發(fā)而成。主要作用是提供servlet和jsp類庫；tomcat是一個免費開源的web服務器，它和nginx、httpd服務不同的是，它不擅長處理HTML代碼，更多的是處理JSP程序；有點類似fpm服務專門處理php程序；
jdk：java開發(fā)工具箱（Java Development Kit），主要提供java開發(fā)相關工具包，庫文件以及jre和jvm相關組件，可以理解為java編程語言的一個基礎標準庫環(huán)境相關組件包和開發(fā)公具相關組件。
jre：java運行時環(huán)境（Java runtime environment），該軟件主要提供運行Java程序的環(huán)境；我們可以理解jre就是jvm和一些標準類庫組成的一個Java程序運行環(huán)境；
提示：從上面的圖可以了解到JDK包含JRE，JRE包含jvm；
jvm：Java虛擬機（Java virtual machine）主要作用是讓Java程序實現(xiàn)跨平臺，我們可以理解Java虛擬機的作用就是在轉換不同操作系統(tǒng)底層的API；這樣一來Java程序員就直接面向jvm提供的API進行編程，從而不用考慮其他操作系統(tǒng)底層API的不同；如下圖
提示：從上圖就可以了解到jvm的重要性，它可以實現(xiàn)程序員一次編碼，到處運行，正是jvm解決了底層操作系統(tǒng)不同API問題，使得java程序可以在任何具有jvm的設備上運行；
二、JDK安裝
1、oracle jdk安裝
oracle jdk 是oracle官方提供的一個jdk，安裝我們可以直接去官方下載對應版本的包，到本地服務器即可；官方下載地址https://www.oracle.com/cn/java/technologies/javase-downloads.html；
提示：我這里是提前下載好了的，上面官方地址還需要注冊挺麻煩的；下載好rpm ，然后直接使用yum安裝即可
[root@lxc java]# yum install ./jdk-8u211-linux-x64.rpm Loaded plugins: fastestmirror Examining ./jdk-8u211-linux-x64.rpm: 2000:jdk1.8-1.8.0_211-fcs.x86_64 Marking ./jdk-8u211-linux-x64.rpm to be installed Resolving Dependencies --> Running transaction check ---> Package jdk1.8.x86_64 2000:1.8.0_211-fcs will be installed --> Finished Dependency Resolution Dependencies Resolved ==================================================================================================== Package Arch Version Repository Size ==================================================================================================== Installing: jdk1.8 x86_64 2000:1.8.0_211-fcs /jdk-8u211-linux-x64 297 M Transaction Summary ==================================================================================================== Install 1 Package Total size: 297 M Installed size: 297 M Is this ok [y/d/N]: y Downloading packages: Running transaction check Running transaction test Transaction test succeeded Running transaction Installing : 2000:jdk1.8-1.8.0_211-fcs.x86_64 1/1 Unpacking JAR files... tools.jar... plugin.jar... javaws.jar... deploy.jar... rt.jar... jsse.jar... charsets.jar... localedata.jar... Verifying : 2000:jdk1.8-1.8.0_211-fcs.x86_64 1/1 Installed: jdk1.8.x86_64 2000:1.8.0_211-fcs Complete! [root@lxc java]#
提示：當然直接使用rpm -ivh 也是可以直接安裝的，這個jdk幾乎沒有依賴關系，所以可以直接通過rpm安裝；通常有依賴關系的包建議還是使用yum去解決依賴關系；
查看jdk-8u211-linux-x64.rpm生成的文件
[root@lxc java]# rpm -qpi ./jdk-8u211-linux-x64.rpm warning: ./jdk-8u211-linux-x64.rpm: Header V3 RSA/SHA256 Signature, key ID ec551f03: NOKEY Name : jdk1.8 Epoch : 2000 Version : 1.8.0_211 Release : fcs Architecture: x86_64 Install Date: (not installed) Group : Development/Tools Size : 311820630 License : https://java.com/bc_license Signature : RSA/SHA256, Tue 02 Apr 2019 12:06:57 AM EDT, Key ID 72f97b74ec551f03 Source RPM : jdk1.8-1.8.0_211-fcs.src.rpm Build Date : Mon 01 Apr 2019 11:55:52 PM EDT Build Host : java.com Relocations : /usr/java Vendor : Oracle Corporation URL : http://www.oracle.com/technetwork/java/javase/overview/index.html Summary : Java Platform Standard Edition Development Kit Description : The Java Platform Standard Edition Development Kit (JDK) includes both the runtime environment (Java virtual machine, the Java platform classes and supporting files) and development tools (compilers, debuggers, tool libraries and other tools).

[root@lxc java]# rpm -ql jdk1.8 /usr /usr/java /usr/java/jdk1.8.0_211-amd64 /usr/java/jdk1.8.0_211-amd64/.java /usr/java/jdk1.8.0_211-amd64/.java/.systemPrefs /usr/java/jdk1.8.0_211-amd64/.java/.systemPrefs/.system.lock /usr/java/jdk1.8.0_211-amd64/.java/.systemPrefs/.systemRootModFile /usr/java/jdk1.8.0_211-amd64/.java/init.d /usr/java/jdk1.8.0_211-amd64/.java/init.d/jexec /usr/java/jdk1.8.0_211-amd64/COPYRIGHT /usr/java/jdk1.8.0_211-amd64/LICENSE /usr/java/jdk1.8.0_211-amd64/README.html /usr/java/jdk1.8.0_211-amd64/THIRDPARTYLICENSEREADME-JAVAFX.txt /usr/java/jdk1.8.0_211-amd64/THIRDPARTYLICENSEREADME.txt /usr/java/jdk1.8.0_211-amd64/bin /usr/java/jdk1.8.0_211-amd64/bin/ControlPanel /usr/java/jdk1.8.0_211-amd64/bin/appletviewer /usr/java/jdk1.8.0_211-amd64/bin/extcheck ……省略部分內(nèi)容
提示：下載好的rpm包安裝后，如果要查詢其對應安裝了那些文件，我們首先要知道它的名稱是什么，用rpm -qpi命令可以查看到對應名稱，然后我們再通過rpm -ql查看對應名稱的軟件安裝生成了那些文件；從上面的信息可以看到jdk1.8生成的文件都在/usr/java/目錄下；
提示：從上面的截圖可以了解到在/usr/java/目錄下有兩個軟連接，default默認指向了latest這個軟連接，latest軟連接指向了jdk1.8；這意味著jdk可以同時存在多個版本，我們只需要把對應軟連接修改了即可更新到新的版本；這里需要提醒下，如果多版本并存的情況，我們可以使用alternatives工具來切換；
alternatives工具多版本相互切換
切換前，默認使用1.8.0.211版本
[root@lxc java]# alternatives --config java There is 1 program that provides 'java'. Selection Command ----------------------------------------------- *+ 1 /usr/java/jdk1.8.0_211-amd64/jre/bin/java Enter to keep the current selection[+], or type selection number: 1 [root@lxc java]# alternatives --install /usr/bin/java java /usr/java/jdk1.7.0_79/bin/java 2 [root@lxc java]# alternatives --config java There are 2 programs which provide 'java'.

Selection Command ----------------------------------------------- * 1 /usr/java/jdk1.8.0_211-amd64/jre/bin/java + 2 /usr/java/jdk1.7.0_79/bin/java Enter to keep the current selection[+], or type selection number: 1 [root@lxc java]# java -version java version "1.8.0_211" Java(TM) SE Runtime Environment (build 1.8.0_211-b12) Java HotSpot(TM) 64-Bit Server VM (build 25.211-b12, mixed mode) [root@lxc java]#
提示：可以看到可以根據(jù)自己需要來回切換jdk的版本；到此oracle jdk的安裝就完成了；
2、openjdk安裝
[root@docker_node01 ~]# yum install java-1.8.0-openjdk Loaded plugins: fastestmirror base | 3.6 kB 00:00:00 docker-ce-stable | 3.5 kB 00:00:00 epel | 4.7 kB 00:00:00 extras | 2.9 kB 00:00:00 updates | 2.9 kB 00:00:00 (1/4): epel/x86_64/updateinfo | 1.0 MB 00:00:00 (2/4): extras/7/x86_64/primary_db | 205 kB 00:00:00 (3/4): updates/7/x86_64/primary_db | 3.0 MB 00:00:01 (4/4): epel/x86_64/primary_db | 6.8 MB 00:00:01 Loading mirror speeds from cached hostfile * base: mirror.bit.edu.cn * extras: mirror.bit.edu.cn * updates: mirror.bit.edu.cn Resolving Dependencies --> Running transaction check ---> Package java-1.8.0-openjdk.x86_64 1:1.8.0.252.b09-2.el7_8 will be installed --> Processing Dependency: java-1.8.0-openjdk-headless(x86-64) = 1:1.8.0.252.b09-2.el7_8 for package: 1:java-1.8.0-openjdk-1.8.0.252.b09-2.el7_8.x86_64 --> Processing Dependency: xorg-x11-fonts-Type1 for package: 1:java-1.8.0-openjdk-1.8.0.252.b09-2.el7_8.x86_64 --> Processing Dependency: libjvm.so(SUNWprivate_1.1)(64bit) for package: 1:java-1.8.0-openjdk-1.8.0.252.b09-2.el7_8.x86_64 ……省略部分內(nèi)容 Installed: java-1.8.0-openjdk.x86_64 1:1.8.0.252.b09-2.el7_8 Dependency Installed: atk.x86_64 0:2.28.1-2.el7 cairo.x86_64 0:1.15.12-4.el7 copy-jdk-configs.noarch 0:3.3-10.el7_5 cups-libs.x86_64 1:1.6.3-43.el7 fribidi.x86_64 0:1.0.2-1.el7_7.1 gdk-pixbuf2.x86_64 0:2.36.12-3.el7 giflib.x86_64 0:4.1.6-9.el7 graphite2.x86_64 0:1.3.10-1.el7_3 gtk-update-icon-cache.x86_64 0:3.22.30-5.el7 gtk2.x86_64 0:2.24.31-1.el7 harfbuzz.x86_64 0:1.7.5-2.el7 hicolor-icon-theme.noarch 0:0.12-7.el7 jasper-libs.x86_64 0:1.900.1-33.el7 java-1.8.0-openjdk-headless.x86_64 1:1.8.0.252.b09-2.el7_8 javapackages-tools.noarch 0:3.4.1-11.el7 jbigkit-libs.x86_64 0:2.0-11.el7 libICE.x86_64 0:1.0.9-9.el7 libSM.x86_64 0:1.2.2-2.el7 libXcomposite.x86_64 0:0.4.4-4.1.el7 libXcursor.x86_64 0:1.1.15-1.el7 libXdamage.x86_64 0:1.1.4-4.1.el7 libXext.x86_64 0:1.3.3-3.el7 libXfixes.x86_64 0:5.0.3-1.el7 libXft.x86_64 0:2.3.2-2.el7 libXi.x86_64 0:1.7.9-1.el7 libXinerama.x86_64 0:1.1.3-2.1.el7 libXrandr.x86_64 0:1.5.1-2.el7 libXrender.x86_64 0:0.9.10-1.el7 libXtst.x86_64 0:1.2.3-1.el7 libXxf86vm.x86_64 0:1.1.4-1.el7 libfontenc.x86_64 0:1.1.3-3.el7 libglvnd.x86_64 1:1.0.1-0.8.git5baa1e5.el7 libglvnd-egl.x86_64 1:1.0.1-0.8.git5baa1e5.el7 libglvnd-glx.x86_64 1:1.0.1-0.8.git5baa1e5.el7 libthai.x86_64 0:0.1.14-9.el7 libtiff.x86_64 0:4.0.3-32.el7 libwayland-client.x86_64 0:1.15.0-1.el7 libwayland-server.x86_64 0:1.15.0-1.el7 libxshmfence.x86_64 0:1.2-1.el7 lksctp-tools.x86_64 0:1.0.17-2.el7 mesa-libEGL.x86_64 0:18.3.4-7.el7_8.1 mesa-libGL.x86_64 0:18.3.4-7.el7_8.1 mesa-libgbm.x86_64 0:18.3.4-7.el7_8.1 mesa-libglapi.x86_64 0:18.3.4-7.el7_8.1 pango.x86_64 0:1.42.4-4.el7_7 pcsc-lite-libs.x86_64 0:1.8.8-8.el7 pixman.x86_64 0:0.34.0-1.el7 python-javapackages.noarch 0:3.4.1-11.el7 python-lxml.x86_64 0:3.2.1-4.el7 ttmkfdir.x86_64 0:3.0.9-42.el7 tzdata-java.noarch 0:2020a-1.el7 xorg-x11-font-utils.x86_64 1:7.5-21.el7 xorg-x11-fonts-Type1.noarch 0:7.5-9.el7 Dependency Updated: glib2.x86_64 0:2.56.1-5.el7 libdrm.x86_64 0:2.4.97-2.el7 Complete! [root@docker_node01 ~]#
提示：安裝openjdk使用yum安裝需要注意命名，通常是java-版本號-openjdk；到此openjdk就安裝好了，后續(xù)的版本切換也可以使用alternatives命令來切換即可和oracle jdk使用沒有特別的不同；除了以上方式安裝，當然我們也可以去下載二進制包，直接展開就可以，二進制包安裝需要注意創(chuàng)建環(huán)境變量文件；好了安裝jdk就不過多闡述了；接下來我們就可以安裝tomcat了；
三、tomcat安裝

提示：tomcat默認監(jiān)聽在tcp的8080端口；
測試：用瀏覽器訪問對應服務器上的8080端口，看看是否訪問到tomcat的默認提供的頁面？
提示：可以看到用瀏覽器展示訪問不到對應頁面，提示我們404；這說明我們訪問的頁面不存在，原因是我們只安裝了tomcat的程序包，并沒有安裝任何webapp，所以對應目錄下都沒有頁面存在，所以我們現(xiàn)在訪問提示我們404；

提示：可以看到在/usr/share/tomcat/webapps/下已經(jīng)有文件生成了，接下來我們再用瀏覽器訪問下8080端口，看看是否能夠訪問到頁面呢？
提示：可以看到我們能夠正常訪問到頁面，說明tomcat環(huán)境搭建已經(jīng)完成；后續(xù)我們就可以把java開發(fā)的一些jsp程序部署到tomcat上使用了；

提示：啟動tomcat要使用內(nèi)部的shell腳本catalina.sh 來啟動；當然startup.sh也是可以的；可以看到8080端口已經(jīng)處于監(jiān)聽的狀態(tài)，接下來我們用瀏覽器嘗試訪問下，看看是否能夠訪問到頁面？
提示：可以看到tomcat提供的頁面我們是能夠正常訪問，說明我們安裝部署的tomcat環(huán)境就準備就緒了；到此tomcat環(huán)境安裝就部署完畢了；總結一點，部署tomcat環(huán)境，首先要安裝jdk，因為tomcat本身就是java語言編寫，我們要在服務器上安裝好java程序運行環(huán)境和標準類庫等組件，tomcat才可以服務器上正常的運行起來；其實從上面的演示我們大概也能知道tomcat就是為Java jsp程序提供一個運行環(huán)境，后續(xù)的jsp代碼主要就是在tomcat上運行，而非jdk上；jdk是運行Java程序（tomcat）而必須有的組件；后續(xù)本人會持續(xù)更新有關tomcat配置使用相關的話題，感興趣的同學可以關注關注；
