問(wèn)題描述

我先啟動(dòng)nginx后，在啟動(dòng)tomcat，IDEA會(huì)有如下圖所示提示，然后訪問(wèn)jsp頁(yè)面訪問(wèn)不了。然后如果我先啟動(dòng)tomcat，在啟動(dòng)nginx的時(shí)候,nginx會(huì)啟動(dòng)失敗,start nginx后，進(jìn)程列表里面沒(méi)有nginx

這是我的nginx.conf

剛剛那個(gè)問(wèn)題解決了 目前遇到另一個(gè)問(wèn)題訪問(wèn)nginx8081向tomcat轉(zhuǎn)發(fā)的時(shí)候 速度特別慢F12看了一下。。到40秒才開(kāi)始Load頁(yè)面，之前的都失敗了，不知道為什么

問(wèn)題解答

出現(xiàn)了問(wèn)題的話應(yīng)該首先分析一下報(bào)的錯(cuò)，而不是直接就問(wèn)，要培養(yǎng)分析能力以及解決問(wèn)題的能力。像這個(gè)報(bào)錯(cuò)已經(jīng)很明顯了：翻譯過(guò)來(lái)就是競(jìng)爭(zhēng)端口，也就是不同的程序用了相同的端口了。

一般情況下端口不能被多個(gè)進(jìn)程使用，Tomcat 使用了 8080 端口，nginx 就不行了。同理 nginx 先啟動(dòng)的話，已經(jīng)把 8080 端口占用了，Tomcat 想使用這個(gè)端口是不行的。

解決辦法就是 把 nginx 換監(jiān)聽(tīng)成 80 端口：

server {listen 80;server_name localhost;......

也可以換 Tomcat 的端口，但是沒(méi)必要。 nginx 作為前端的話應(yīng)該用 80 ，Tomcat 隨意。
