基于安全策略来考虑，绝大多数应用程序都应以非root用户来启动，对于轻量级的应用程序，如tomcat，用root再寻常不过了。你懂的，方便啊。在生产环境这么干很容易被攻击者通过脚本干太多的事情了。因此生产环境就还是麻烦一点吧，使用非root用户来启动。本文演示了基于非root用户启动tomcat，同时将其作为一个daemon服务随服务器自启动。

一、演示环境描述

OS及tomcat版本
  [root@node132 ~]# more /etc/redhat-release
  CentOS release 6.7 (Final)
  [root@node132 ~]# /usr/local/tomcat/bin/catalina.sh version
  Using CATALINA_BASE: /usr/local/tomcat
  Using CATALINA_HOME: /usr/local/tomcat
  Using CATALINA_TMPDIR: /usr/local/tomcat/temp
  Using JRE_HOME: /usr/local/src/jdk1.7.0_79
  Using CLASSPATH: /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
  Server version: Apache Tomcat/7.0.69
  Server built: Apr 11 2016 07:57:09 UTC
  Server number: 7.0.69.0
  OS Name: Linux
  OS Version: 2.6.32-573.el6.x86_64
  Architecture: amd64
  JVM Version: 1.7.0_79-b15
  JVM Vendor: Oracle Corporation

Java环境变量
  [root@node132 ~]# env|grep JAVA
  JAVA_HOME=/usr/local/src/jdk1.7.0_79

二、配置tomcat daemon服务及自启动

添加tomcat用户及组
  [root@node132 ~]# groupadd tomcat
  [root@node132 ~]# useradd -s /sbin/nologin -g tomcat tomcat
  [root@node132 ~]# usermod -L tomcat

配置启动脚本
  [root@node132 ~]# cd /usr/local/tomcat/bin/
  [root@node132 bin]# tar -xf commons-daemon-native.tar.gz
  [root@node132 bin]# cd commons-daemon-1.0.15-native-src/unix/
  [root@node132 unix]# ./configure --with-java=/usr/local/src/jdk1.7.0_79
  [root@node132 unix]# make
  [root@node132 unix]# cp jsvc /usr/local/tomcat/bin/.

  [root@node132 bin]# vim daemon.sh
  #!/bin/sh

  #chkconfig: 235 80 20 ##当前行开始添加下列行
  #description:tomcatd

  JAVA_HOME=/usr/local/src/jdk1.7.0_79 ##Author : Leshami
  CATALINA_HOME=/usr/local/tomcat ##Blog : http://blog.csdn.net/leshami
  TOMCAT_USER=tomcat

  #ARG0="$0" ##注释此行，用下一行替换
  ARG0=/usr/local/tomcat

配置自启动
  [root@node132 bin]# cp daemon.sh /etc/init.d/tomcatd
  [root@node132 bin]# chkconfig --add tomcatd
  [root@node132 bin]# chkconfig tomcatd on

  [root@node132 bin]# chown -R tomcat:tomcat /usr/local/tomcat
  [root@node132 bin]# /etc/init.d/tomcatd start

  [root@node132 local]# ss -nltp|grep jsvc
  LISTEN 0 100 :::8009 :::* users:(("jsvc",15942,45))
  LISTEN 0 100 :::8080 :::* users:(("jsvc",15942,44))

  [root@node132 local]# ps -ef|grep tomcat
  root 16293 1 0 17:10 ? 00:00:00 jsvc.exec -java-home /usr/local/..
  tomcat 16294 16293 2 17:10 ? 00:00:02 jsvc.exec -java-home /usr/local/..

测试
  [root@node132 local]# curl -I http://localhost:8080
  HTTP/1.1 200 OK
  Server: Apache-Coyote/1.1
  Content-Type: text/html;charset=ISO-8859-1
  Transfer-Encoding: chunked

三、基于su命令实现非root非daemon方式

直接使用su - tomcat方式来实现非root用户运行tomcat程序

  [root@node132 ~]# vim /etc/init.d/tomcat
  #!/bin/sh
  # Tomcat init script for Linux.
  #
  # chkconfig: 2345 96 14
  # description: The Apache Tomcat servlet/JSP container.
  JAVA_HOME=/usr/java/latest
  CATALINA_HOME=/usr/local/tomcat-su
  export JAVA_HOME CATALINA_HOME
  su - tomcat -c "exec $CATALINA_HOME/bin/catalina.sh $*" ##关键是这行

  [root@node132 ~]# /etc/init.d/tomcat start ##需要解锁账户
  This account is currently not available.

  [root@node132 ~]# usermod -U -s /bin/bash tomcat
  usermod: unlocking the user's password would result in a passwordless account.
  You should set a password with usermod -p to unlock this user's password.
  [root@node132 ~]# /etc/init.d/tomcat start
  Using CATALINA_BASE: /usr/local/tomcat
  Using CATALINA_HOME: /usr/local/tomcat
  Using CATALINA_TMPDIR: /usr/local/tomcat/temp
  Using JRE_HOME: /usr/local/src/jdk1.7.0_79
  Using CLASSPATH: /usr/local/tomcat/bin/bootstrap.jar:
  Tomcat started.

  [root@node132 ~]# ps -ef|grep tomcat
  tomcat 16600 1 69 17:25 ? 00:00:02 /usr/local/src/jdk1.7

  [root@node132 ~]# curl -I http://localhost:8080
  HTTP/1.1 200 OK
  Server: Apache-Coyote/1.1
  Content-Type: text/html;charset=ISO-8859-1
  Transfer-Encoding: chunked
  Date: Thu, 02 Nov 2017 09:20:54 GMT

四、基于sudo命令实现非root非daemon方式

  [root@node132 ~]# sudo su - tomcat /usr/local/tomcat/bin/catalina.sh start
  Using CATALINA_BASE: /usr/local/tomcat
  Using CATALINA_HOME: /usr/local/tomcat
  Using CATALINA_TMPDIR: /usr/local/tomcat/temp
  Using JRE_HOME: /usr/local/src/jdk1.7.0_79
  Using CLASSPATH: /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
  Tomcat started.
  [root@node132 ~]# ps -ef|grep tomcat
  tomcat 16523 1 64 17:24 pts/0 00:00:02 /usr/local/src/jdk1.7.0_79/bin....
