在服務器跑Java程序的時候，經常用的Web服務器就是Tomcat，今天用yum命令試着安裝了一下。

編譯安裝的時候需要安裝JDK和Tomcat，而yum安裝Tomcat直接把OpenJDK也給安裝上了。

yum安裝Tomcat

先查看一下yum安裝時的Tomcat版本

 

 

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

# yum info tomcat Loaded plugins: security Available Packages Name        : tomcat Arch        : noarch Version     : 7.0.33 Release     : 4.el6 Size        : 86 k Repo        : epel Summary     : Apache Servlet/JSP Engine, RI for Servlet 3.0/JSP 2.2 API URL         : http://tomcat.apache.org/ License     : ASL 2.0 Description : Tomcat is the servlet container that is used in the official Reference             : Implementation for the Java Servlet and JavaServer Pages technologies.             : The Java Servlet and JavaServer Pages specifications are developed by             : Sun under the Java Community Process.             :             : Tomcat is developed in an open and participatory environment and             : released under the Apache Software License version 2.0.

Tomcat最新版本是2015/11/24發布的Tomcat8.0.29，而yum安裝版本是2012/11/21發布的7.0.33(版本確實低了)。

安裝Tomcat

安裝Tomcat之后，查看安裝的版本。

 

 

1 2 3 4 5 6 7 8 9 10 11

# yum install tomcat   # tomcat version Server version: Apache Tomcat/7.0.33 Server built:   Apr 30 2014 09:16:58 Server number:  7.0.33.0 OS Name:        Linux OS Version:     2.6.32-573.8.1.el6.x86_64 Architecture:   amd64 JVM Version:    1.8.0_65-b17 JVM Vendor:     Oracle Corporation

安裝Tomcat時直接把OpenJDK也安裝了

在這里可以看到安裝的JDK不是Oracle的JDK而是OpenJDK。

 

 

1 2 3 4

# java -version openjdk version "1.8.0_65" OpenJDK Runtime Environment (build 1.8.0_65-b17) OpenJDK 64-Bit Server VM (build 25.65-b01, mixed mode)

可以使用alternatives切換使用的Java版本。

 

 

1 2 3 4 5 6 7 8

# alternatives --config java   There are 2 programs which provide 'java'.     Selection    Command -----------------------------------------------    1           /usr/lib/jvm/jre-1.5.0-gcj/bin/java *+ 2           /usr/lib/jvm/jre-1.8.0-openjdk.x86_64/bin/java

使用Tomcat管理頁面

訪問Tomcat管理頁面(http://localhost:8080/manager/html)需要安裝tomcat-admin-webapps和修改tomcat-users.xml文件。

安裝tomcat-admin-webapps

 

 

1	# yum install tomcat-admin-webapps

修改tomcat-users.xml文件

修改tomcat-users.xml文件(默認安裝目錄是/etc/tomcat)，添加46-48行的內容。

/etc/tomcat/tomcat-users.xml

訪問Tomcat管理頁面

訪問http://localhost:8080/manager/html，並輸入48行里設定的username和password，就可以了。
