问题：

需要在引导时启动tomcat

$sudo chkconfig --add tomcat  
-bash: chkconfig: command not found

我以为它没有安装，但它是在地方。

$sudo yum install chkconfig
Loaded plugins: fastestmirror
Repository base is listed more than once in the configuration
Repository updates is listed more than once in the configuration
Repository addons is listed more than once in the configuration
Repository extras is listed more than once in the configuration

Repository contrib is listed more than once in the configuration
Loading mirror speeds from cached hostfile

Setting up Install Process
Package chkconfig-1.3.30.2-2.el5.x86_64 already installed and latest version
Nothing to do

在Google上快速搜索后发现，它可能位于/sbin/chkconfig。

$sudo /sbin/chkconfig
chkconfig version 1.3.30.2 - Copyright (C) 1997-2000 Red Hat, Inc.

usage:   chkconfig --list [name]
         chkconfig --add <name>
         chkconfig --del <name>
         chkconfig [--level <levels>] <name> <on|off|reset|resetpriorities>

bash希望chkconfig脚本其中？

$sudo which chkconfig
which: no chkconfig in (/usr/bin:/bin)

好的，让我们创建一个符号链接

sudo ln -s /sbin/chkconfig /usr/bin/

现在能用了吗？
