1.使用startup命令無法啟動tomcat
[[email protected] ~]# ps -ef |grep tomcatAPP
root 14565 14548 0 11:09 pts/0 00:00:00 grep tomcatAPP
[[email protected] ~]# cd /usr/local/tomcatAPP
[[email protected] tomcatAPP]# ./bin/startup.sh
Using CATALINA_BASE: /usr/local/tomcatAPP
Using CATALINA_HOME: /usr/local/tomcatAPP
Using CATALINA_TMPDIR: /usr/local/tomcatAPP/temp
Using JRE_HOME: /usr/local/jdk1.8.0_121
Using CLASSPATH: /usr/local/tomcatAPP/bin/bootstrap.jar:/usr/local/tomcatAPP/bin/tomcat-juli.jar
Tomcat started. # 顯示tomcat啟動
# 檢視是否成功啟動tomcat，結果是未成功啟動
[ 2.原因
在tomcat的server.xml中配置了虛擬目錄，訪問地址是/時預設訪問APPPortal目錄。
檢查webapps下的檔案時，發現沒有APPPortal目錄，導致tomcat啟動失敗。
[[email protected] tomcatAPP]# cat ./conf/server.xml .... <Host name="localhost" appBase="webapps" unpackWARs="true" autoDeploy="true"> <!-- Context中配置的是虛擬目錄，要求訪問/時，預設訪問APPPortal目錄 --> <Context path="/" docBase="APPPortal" debug="0" reloadable="true"/> <!-- SingleSignOn valve, share authentication between web applications Documentation at: /docs/config/valve.html --> <!-- <Valve className="org.apache.catalina.authenticator.SingleSignOn" /> --> <!-- Access log processes all example. Documentation at: /docs/config/valve.html Note: The pattern used is equivalent to using pattern="common" --> <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" prefix="localhost_access_log." suffix=".txt" pattern="%h %l %u %t "%r" %s %b" /> </Host> </Engine> </Service> </Server>

3.解決方案
釋放一個APPPortal.war檔案，啟動成功。
[[email protected] tomcatAPP]# ll ./webapps/
