首先我们需要为tomcat配置JAVA的环境变量, 直接写到 setclasspath.sh 文件的开头即可, 我写入的内容如下所示
#--------------------- # java path #--------------------- JAVA_HOME=/usr/lib/jvm/java-8-oracle JRE_HOME=$JAVA_HOME/jre JAVA_BIN=$JAVA_HOME/bin CLASSPATH=$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin export JAVA_HOME JRE_HOME PATH CLASSPATH刚开始的时候, 在 CLASSPATH 的开始配置了当前目录.
即
CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib导致运行的时候老是出错, 其主要就是运行环境找不到, 因为 tomcat 运行需要 bootstrap.jar 和 tomcat-juli.jar, 运行的时候在当前 bin 目录下找到了这两个 bin 包, 但是关闭服务的时候, 目录更改了这两个 jar 包就没有找到, 导致服务能起来, 但是却结束不了
运行环境检查
配置完 JAVA 之后, 检查运行环境是否正确
sudo sh configtest.sh我们提到了 catalina.sh 脚本其实就是一个完备的服务集合, 因此上面的命令等价于
sudo sh catalina.sh configtestconfigtest.sh 脚本其实就是运行了catalina.sh configtest 命令, 这点可以从其源码中看到
PRGDIR=`dirname "$PRG"` EXECUTABLE=catalina.sh exec "$PRGDIR"/"$EXECUTABLE" configtest "$@"如果 ERROR 的话, 说明没有配置没有问题
直接运行
sudo ./startup.sh等价于
sudo sh catalina.sh start
关闭
./shutdown.sh等价于
sudo sh catalina.sh stop打开:8080
catalina.sh 脚本可以直接作为服务来使用, 我们做一个了链接即可
cd /etc/init.d sudo ln -s /opt/apache-tomcat/catalina.sh ./tomcat8
当然我们也可以自己做一个

service tomcat8 start OR etc/init.d/tomcat8 start停止 tomcat8
service tomcat8 stop OR etc/init.d/tomcat8 stop
