tomcat

安装配置

• 下载

  https://tomcat.apache.org/download-80.cgi (opens new window)

• 复制到指定位置: sudo cp apache-tomcat-8.5.57.tar.gz /usr/local/lib/

• 进入目录/usr/local/lib/ sudo tar -zxvf apache-tomcat-8.5.57.tar.gz

• 赋予权限 sudo chmod 755 -R apache-tomcat-8.5.57

• 配置环境变量

  sudo vi startup.sh

#set java environment
export JAVA_HOME=/usr/local/lib/jdk1.8.0_261
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=.:${JAVA_HOME}/bin:$PATH

#tomcat
export TOMCAT_HOME=/usr/local/lib/apache-tomcat-8.5.57

sudo vi setclasspath.sh 环境变量配置到上面

export JAVA_HOME=/usr/local/lib/jdk1.8.0_261
export JRE_HOME=/usr/local/lib/jdk1.8.0_261/jre

• 启动服务

sudo ./startup.sh

问题

• 1.Neither the JAVA_HOME nor the JRE_HOME environment variable is defined

环境变量需要配置到上面/java环境变量不对
