查看服务器tomcat版本

一、通过tomcat版本文件查看

　　找到tomcat目录，进入”xxx/tomcat/bin” 目录，执行”sh version.sh”。如果没有设置JAVA_HOME和JRE_HOME环境变量则会报如下错误：

[jerry@host xxx/tomcat/bin]
$sh version.sh
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

　　设置JAVA_HOME和JRE_HOME环境变量：

export JAVA_HOME=xxx/java/
export JRE_HOME=xxx/java/jre/

　　执行”sh version.sh”返回当前tomcat版本信息：

$sh version.sh
Using CATALINA_BASE:   xxx/tomcat
Using CATALINA_HOME:   xxx/tomcat
Using CATALINA_TMPDIR: xxx/tomcat/temp
Using JRE_HOME:        xxx/java/jre/
Using CLASSPATH:       xxx/tomcat/bin/bootstrap.jar:xxx/tomcat/bin/tomcat-juli.jar
Using CATALINA_PID:    xxx/tomcat/catalina.pid

二、通过tomcat启动文件查看

　　找到tomcat启动文件，本文是yyy/tomcat_stdout.log，搜索”Starting Servlet Engine”则可看到当前启动的容器版本。
