同学的服务器redis也部署上去了？然后服务器连的是服务器的Redis吧？如果是，用redis-cli登录到服务器的redis上面 执行 flushall指令试试

The main resource set specified [/root/apache-tomcat-8.0.46/webapps/o2oImage/image/upload] is not valid 不建议同学把图片放到/root/目录下，放到别的,可以是/home/work下面，也就是Server.xml里面得docBase路径。。 然后确保已经创建出来了

同学好，这里报的是你的server.xml的解析有问题呢，应该是写得格式不对，你是不是做了什么改动，建议先还原成原先的。

同学好，Caused by: java.net.BindException: Address already in use

主要是端口被别的程序占用了，同学看看 80 8080 或者你server.xml里面出现的所有端口 看看哪个被占用了

通过netstat -apn | grep 端口号  来看看
