Linux简单添加tomcat服务

先上脚本文件
文件名tomcat8081

tomcat_pid() {
  echo `ps -ef | grep $CATALINA_HOME/ | grep -v grep | tr -s " "|cut -d" " -f2`
}

start() {
  pid=$(tomcat_pid)
  if [ -n "$pid" ]; then
    echo -e "\e[00;31mTomcat is already running (pid: $pid)\e[00m"

    tail -f $CATALINA_HOME/logs/catalina.out
}

case $1 in

    echo -e $TOMCAT_USAGE
    ;;
esac
exit 0

将文件放到 /etc/init.d/ 下
运行命令

sudo chmod +x /etc/init.d/tomcat8081

这样就可以在 shell 中直接运行下面的命令

service tomcat8081 start
service tomcat8081 stop
service tomcat8081 restart
service tomcat8081 status
service tomcat8081 logs

遇到的问题

日志文件权限问题

报错如下

提示没有/opt/tomcat/tomcat8081/logs/catalina.out的权限
进入logs目录chmod 777 *
同理配置了conf的权限
