使用普通用户运行

使用普通用户来部署服务是比较安全的做法

[root@tomcat application]# useradd -u 1001 tomcat
[root@tomcat application]# passwd tomcat
Changing password for user tomcat.
New password: 
Retype new password: 
passwd: all authentication tokens updated successfully.
切换到tomcat来执行
[root@tomcat application]# chown -R tomcat:tomcat /application/jdk
[root@tomcat application]# chown -R tomcat:tomcat /application/tomcat/
[root@tomcat application]# su - tomcat 
[tomcat@linux-node1 ~]$ cd /application/tomcat/bin/
[tomcat@linux-node1 bin]$ sh startup.sh   #启动脚本

Using CATALINA_HOME:   /application/tomcat

Using JRE_HOME:        /application/jdk
Using CLASSPATH:       /application/tomcat/bin/bootstrap.jar:/application/tomcat/bin/tomcat-juli.jar
Tomcat started.
[tomcat@linux-node1 tomcat]$ pwd

启动的时候会把临时文件和工作文件放在temp和work，在生产用的时候、建议每次启动将这两个目录清空

 tomcat使用自带的脚本有时候是杀不死进程的 、自己写一个脚本

#!/bin/sh
JAVA_HOME=/application/jdk
CATALINA_HOME=/application/tomcat


usage(){
        echo "$0 {start|stop|restart}"
        exit 1
}
[ $# -ne 1 ]&& usage

start_tomcat(){
         $CATALINA_HOME/bin/startup.sh
}
stop_tomcat(){
TPID=$(ps -aux|grep java|grep tomcat|awk ‘{print $2}‘)
kill -9 $TPID
sleep 5;
TSTAT=$(ps -aux|grep java|grep tomcat|awk ‘{print $2}‘)
if [ -z $TSTAT ];then
        echo "tomcat stop"
else
        kill -9 $TSTAT

fi
}

case $1 in
start)
        start_tomcat
        ;;
stop)
        stop_tomcat
        ;;
restart)
        stop_tomcat
        sleep 5
        start_tomcat
         ;;
*)
        usage
        ;;
esac
[tomcat@linux-node1 ~]$ sh tomcat.sh 
tomcat.sh {start|stop|restart}
[tomcat@linux-node1 ~]$ sh tomcat.sh start
Using CATALINA_BASE:   /application/tomcat
Using CATALINA_HOME:   /application/tomcat
Using CATALINA_TMPDIR: /application/tomcat/temp
Using JRE_HOME:        /application/jdk
Using CLASSPATH:       /application/tomcat/bin/bootstrap.jar:/application/tomcat/bin/tomcat-juli.jar
Tomcat started.


默认监听的是8080端口

[tomcat@linux-node1 ~]$ netstat -ntpl|grep java

 will not be shown, you would have to be root to see it all.)
