[Linux 文章收集] Starting Tomcat as a Linux service

來源自 這裡 
Preface: 
The following bash script file can be used on Linux instances to startup a Tomcat server as a service. The script does need some minor modifications to suit your specific instance of Linux. The following two variables must be changed: 
1. The JAVA_HOME variable must point to an installed version of java on your system. 

# 根據你安裝 JDK 的位置進行調整
export JAVA_HOME=/usr/local/jdk

2. The tomcat_home variable must pouint to an installed Tomact server on your system 

# 根據你置放 Tomcat 目錄進行調整
tomcat_home=/usr/local/jakarta-tomcat

Steps to install on a linux system: 

1. Copy the modified shell script to /etc/init.d/tomcatd
2. Make sure it can be executed: chmod a+x tomcatd 
3. Set up appropriate deamon levels by performing: chkconfig --add tomcatd
