我的 tomcat 启动脚本没有在 Red Hat Enterprise Linux 服务器重新启动时启动 tomcat。
我已将其范围缩小到启动功能：
41 start() {
42 echo "instart $(date)" > /tmp/tomcatscript.out
43 pid=$(tomcat_pid)
44 if [ -n "$pid" ]
45 then
46 echo -e "\e[00;31mTomcat is already running (pid: $pid)\e[00m"
47 else
48 echo "inelse $(date)" >> /tmp/tomcatscript.out
49 # Start tomcat
50 echo -e "\e[00;32mStarting tomcat\e[00m"
51 #ulimit -n 100000
52 #umask 007
53 #/bin/su -p -s /bin/sh $TOMCAT_USER
54 if [ `user_exists $TOMCAT_USER` = "1" ]
55 then
56 echo "in if then PID [$pid] whoami [$(whoami)] $(date)">> /tmp/tomcatscript.out
57 sudo su - $TOMCAT_USER -s /bin/sh -c $CATALINA_HOME/bin/startup.sh >> /tmp/tomcatscript.out
58 else
59 echo "in else $(date)" >> /tmp/tomcatscript.out
60 echo -e "\e[00;31mTomcat user $TOMCAT_USER does not exists. Starting with $(id)\e[00m"
61 sh $CATALINA_HOME/bin/startup.sh
62 fi
63 echo "calling status $(date)">> /tmp/tomcatscript.out
64
65 status >> /tmp/tomcatscript.out
66 fi
67 return 0
68 }
当我重新启动运行 /sbin/reboot 的服务器时，我回显的文件内容是：
# cat /tmp/tomcatscript.out
instart Wed Jun 15 20:24:25 PDT 2016
inelse Wed Jun 15 20:24:25 PDT 2016
in if then PID [] whoami [root] Wed Jun 15 20:24:25 PDT 2016
calling status Wed Jun 15 20:24:25 PDT 2016
Tomcat is not running
当我运行 /etc/rc.d/init.d 中的 tomcat 脚本时，如下所示：
[root@server init.d]# ./tomcat start
该文件的内容如下：
[root@server init.d]# cat /tmp/tomcatscript.out
instart Wed Jun 15 20:38:30 PDT 2016
inelse Wed Jun 15 20:38:30 PDT 2016
in if then PID [] whoami [root] Wed Jun 15 20:38:30 PDT 2016

Tomcat is not running

当我将 CATALINA_HOME 和 CATALINA_BASE 都更改为以下选项时，它现在可以正常工作：
#CATALINA_HOME is the location of the bin files of Tomcat
export CATALINA_HOME=/users/tomcat/apache-tomcat-8.0.30
#CATALINA_BASE is the location of the configuration files of this instance of Tomcat
export CATALINA_BASE=/users/tomcat/apache-tomcat-8.0.30
因此，对我而言有用的整个脚本如下所示：
#!/bin/bash
#

# processname: tomcat
# chkconfig: 234 20 80
