阿里云Tomcat运行shutdown.sh命令关闭时遇到的问题

1.安装完成jdk之后，然后安装tomcat.

tomcat安装成功后，进入tomcat的安装目录，找到bin所在的目录。

使用./startup.sh，启动tomcat;

使用./shutdown.sh关闭Tomcat,有时会关闭成功,有时会出现关闭错误;

切换/usr/local/tomcat/tomcat/logs/查看catalina.out日志记录,发现8005端口号被绑定

INFO: Server startup in 1636696 ms

出现这种情况我们可以使用命令ps -ef | grep tomcat 来查看tomcat是否还在允许

ps -ef | grep tomcat

root              : pts/    :: /usr/lib/jvm/jdk1.8.0_/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= -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 start
root           : pts/    :: grep --color=auto tomcat

如果你想直接杀死Tomcat进程，你可以使用kill命令，直接杀死Tomcat进程

kill - 

继续查看Tomcat是否关闭,如出现以下信息则说明Tomcat已关闭

root           : pts/    :: grep --color=auto tomcat

修改下Tomcat内存，切换到bin目录下面,使用

vim catalina.sh

修改catalina.sh文件，在位置cygwin=false前,插入以下内容

# 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

重启Tomcat即可。
