CentOS-7.0中安装与配置Tomcat-8的方法

安装说明
安装环境：CentOS-7.0.1406
安装方式：源码安装
软件：apache-tomcat-8.5.13.tar.gz
下载地址：http://tomcat.apache.org/download-80.cgi

安装前提

在系统中，我安装的JDK版本是1.8

安装tomcat

创建tomcat目录

mkdir /usr/local/tomcat

将apache-tomcat-8.5.13.tar.gz文件上传到/usr/local/tomcat中执行以下操作：

[root@janus /]# cd /usr/local/tomcat
[root@janus tomcat]# tar -zxv -f apache-tomcat-8.5.13.tar.gz // 解压压缩包
[root@janus tomcat]# rm -rf apache-tomcat-8.5.13.tar.gz // 删除压缩包

启动Tomcat

执行以下操作：

[root@janus /]# /usr/local/tomcat/apache-tomcat-8.5.13/bin/startup.sh

如果出现以下错误

Neither the JAVA_HOME nor the JRE_HOME environment variable is defined
At least one of these environment variable is needed to run this program

先看Tomcat的startup.bat，它调用了catalina.bat,而catalina.bat则调用了setclasspath.bat。只要在setclasspath.bat的开头声明环境变量，打开tomcat的bin目录下面的setclasspath.sh，添加红色部分，路径自己修改。windows 下用set，Linux下用export。

export JAVA_HOME=/usr/local/java/jdk1.8.0_121
export JRE_HOME=/usr/local/java/jdk1.8.0_121/jre

export JAVA_HOME=/usr/local/java/jdk1.8.0_121

rem Make sure prerequisite environment variables are set

rem Otherwise either JRE or JDK are fine

echo Neither the JAVA_HOME nor the JRE_HOME environment variable is defined
echo At least one of these environment variable is needed to run this program
goto exit

:needJavaHome
rem Check if we have a usable JDK
if "%JAVA_HOME%" == "" goto noJavaHome
if not exist "%JAVA_HOME%\bin\java.exe" goto noJavaHome
if not exist "%JAVA_HOME%\bin\javaw.exe" goto noJavaHome
if not exist "%JAVA_HOME%\bin\jdb.exe" goto noJavaHome
if not exist "%JAVA_HOME%\bin\javac.exe" goto noJavaHome
set "JRE_HOME=%JAVA_HOME%"
goto okJava

:noJavaHome
echo The JAVA_HOME environment variable is not defined correctly.
echo It is needed to run this program in debug mode.
echo NB: JAVA_HOME should point to a JDK not a JRE.
goto exit

设置好后，保存当前配置文件。

[root@janus /]# /usr/local/tomcat/apache-tomcat-8.5.13/bin/startup.shUsing CATALINA_BASE:   /usr/local/tomcat/apache-tomcat-8.5.13
Using CATALINA_HOME:   /usr/local/tomcat/apache-tomcat-8.5.13
Using CATALINA_TMPDIR: /usr/local/tomcat/apache-tomcat-8.5.13/temp
Using JRE_HOME:        /usr/local/java/jdk1.8.0_121
Using CLASSPATH:       /usr/local/tomcat/apache-tomcat-8.5.13/bin/bootstrap.jar:/usr/local/tomcat/apache-tomcat-8.5.13/bin/tomcat-juli.jar
Tomcat started.

继续执行tomcat中bin文件夹下的startup.sh

/usr/local/tomcat/apache-tomcat-8.5.13/bin/startup.sh

然后通过浏览器访问



添加项目配置路径

#此配置在tomcat下的conf文件夹下，server.xml中的Host节点下添加项目文件名以及路径
<Context docBase="sparta" path="/sparta" debug="0" privileged="true"/>
