Set Tomcat to automatically start at boot on utuntu

one. Environment:
Operating system: utuntu11.10
JAVA_HOME: /document/opt/jdk1.6
Tomcat installation directory: /documet/opt/tomcat6
II. Write a service startup script Create a file tomcatd
under /etc/init.d/:
#! /bin/sh
# chkconfig: 35 30 70
# descripttion: VirtualBox Linux kernel module
#
### BEGIN INIT INFO

3. Add service:
[root@root init.d]# chmod uog+rx tomcatd
[root@root init.d]# sysv-rc-conf --level 2345 tomcatd on
four. Note:
1. In the comment statement of the first two lines of the tomcat file, you need to include two parts of chkconfig and descriptionttion (make sure not to misspelling), otherwise when "chkconfig --add tomcatd" is executed, "tomcatd service does not support" will appear chkconfig" error message.
2. If prompted that the sysv-rc-conf command does not exist, execute apt-get install sysv-rc-conf to install it.
3. If the tomcat user does not exist, create it through the following command: #useradd -U -s /sbin/nologin tomcat
View the service addition result:
[root@root init.d]# sysv-rc-conf --list tomcatd

tomcatd 2:on 3:on 4:on 5:on
[root@root init.d]# /etc/init.d/tomcatd start
Delete service:
[root@root init.d]# sysv-rc-conf tomcatd off
