接阿里云ECS下安裝jdk1.8安裝成功之后，接下來開始在阿里云部署Tomcat服務器，部署Tomcat和配置jdk類似
1、下載Tomcat,我下載的是apache-tomcat-7.0.75.tar.gz,通過FileZilla上傳至/home/ftp目錄，解壓至/usr/lib/tomcat
sudo tar -zxvf apache-tomcat-7.0.75.tar.gz -C /usr/lib/jvm2、修改~/.bashrc，增加Tomcat環境變量;
export java_HOME=/usr/lib/jvm/jdk1.8.0_121export JRE_HOME=${JAVA_HOME}/jreexport CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/libexport PATH=${JAVA_HOME}/bin:$PATHexport TOMCAT_HOME=/usr/lib/tomcat/apache-tomcat-7.0.753、切換到/usr/lib/tomcat/apache-tomcat-7.0.75/bin/,使用./startup.sh，啟動tomcat;
Using CATALINA_BASE: /usr/lib/tomcat/apache-tomcat-7.0.75Using CATALINA_HOME: /usr/lib/tomcat/apache-tomcat-7.0.75Using CATALINA_TMPDIR: /usr/lib/tomcat/apache-tomcat-7.0.75/tempUsing JRE_HOME: /usr/lib/jvm/jdk1.8.0_121/jreUsing CLASSPATH: /usr/lib/tomcat/apache-tomcat-7.0.75/bin/bootstrap.jar:/usr/lib/tomcat/apache-tomcat-7.0.75/bin/tomcat-juli.jarTomcat started.啟動成功；
4、使用./shutdown.sh關閉Tomcat,有時會關閉成功,有時會出現關閉錯誤;

ps -ef|grep tomcat如顯示以下內容，則說明Tomcat進程還存在著
root 2993 1 0 20:07 pts/1 00:00:04 /usr/lib/jvm/jdk1.8.0_121/jre/bin/java -Djava.util.logging.config.file=/usr/lib/tomcat/apache-tomcat-7.0.75/conf/logging.PRoperties -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djdk.tls.ephemeralDHKeySize=2048 -Djava.endorsed.dirs=/usr/lib/tomcat/apache-tomcat-7.0.75/endorsed -classpath /usr/lib/tomcat/apache-tomcat-7.0.75/bin/bootstrap.jar:/usr/lib/tomcat/apache-tomcat-7.0.75/bin/tomcat-juli.jar -Dcatalina.base=/usr/lib/tomcat/apache-tomcat-7.0.75 -Dcatalina.home=/usr/lib/tomcat/apache-tomcat-7.0.75 -Djava.io.tmpdir=/usr/lib/tomcat/apache-tomcat-7.0.75/temp org.apache.catalina.startup.Bootstrap startroot 3042 2838 0 20:17 pts/1 00:00:00 grep --color=auto tomcat如果你想直接殺死Tomcat進程，你可以使用kill命令，直接殺死Tomcat進程
kill -9 2993繼續查看Tomcat是否關閉,如出現以下信息則說明Tomcat已關閉
root 3044 2838 0 20:20 pts/1 00:00:00 grep --color=auto tomcat6、最近修改下Tomcat內存，切換到bin目錄下面,使用
vi catalina.sh修改catalina.sh文件，在位置cygwin=false前,插入以下內容
# OS specific support. $var _must_ be set to either true or false.JAVA_OPTS="-Xms256m -Xmx512m -Xss1024K -XX:PermSize=128m -XX:MaxPermSize=256m"cygwin=false重啟Tomcat即可。
