s28 LNMP架构服务搭建

發布時間：2024/9/3 编程问答 26 豆豆

生活随笔收集整理的這篇文章主要介紹了 s28 LNMP架构服务搭建小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

nginx-location使用

location語法

location使用的語法例子為：location [=|~|~*|^~] uri{對location語法列表說明。|1ocation | [=|~|~*|^~] |uri |{..}.|指令 |匹配標識。 |匹配的網站網址。|匹配URI后要執行的配置段。上述語法中的URI部分是關鍵，這個URI可以是普通的字符串地址路徑或者是正則表達式，當匹配成功則執行后面大括號里面的相關指令。正則表達式的前面還可以有~或~*等特殊的字符。這兩種特殊字符~或~*匹配的區別為：“ ~ ” 用于區分天小寫(大小寫敏感)的匹配；~/images{}“ ~* ” 用于不區分大小寫的匹配。還可以用邏輯操作符！對上面的匹配取反，即！~ 和！~* 。“ ^~ ” 作用是在常規的字符串匹配檢查之后，不做正則表達式的檢查，即如果最明確的那個字符

實現配置

[root@www extra]# cat www.confserver {listen 80;server_name www.etiantian.org etiantian.org;root html/www;location / {return 401;}location = / {return 402;}location /documents/ {return 403;}location ^~ /images/ {return 404;}location ~* \.(gif|jpg|jpeg)$ {return 500;}access_log logs/access_www.log main ;}x1[root@www extra]# cat www.conf2 ? server {3 ? ? ? listen ? ? ? 80;4 ? ? ? server_name www.etiantian.org etiantian.org;5 ? ? ? root ? html/www;6 ? ? ? 7 ? ? ? location / {8 ? ? ? ? ? return 401;9 ? ? ? }10 ? ? ? location = / {11 ? ? ? ? ? return 402;12 ? ? ? }1314 ? ? ? location /documents/ {15 ? ? ? ? ? return 403;16 ? ? ? }17 ? ? ? location ^~ /images/ {18 ? ? ? ? ? return 404;19 20 ? ? ? }21 22 ? ? ? location ~* \.(gif|jpg|jpeg)$ {23 ? ? ? ? ? return 500;24 ? ? ? }25 ? ? ? access_log logs/access_www.log main ;26 ? }

測試

小結

不用URI及特殊字符組合匹配順序? ? 匹配說明第一名：“location? = / {”? ? 精確匹配/第二名：“location? ^~ /images/ {”? ?? 匹配常規字符串，不做正則匹配檢查, 優先匹配路徑第三名：“location? ~* \.(gif|jpg|jpeg)$ {”? ?? 正則匹配第四名：“location? /documents/ {”? ?? 匹配常規字符串，如果有正則則優先匹配正則。第五名：“location? / {”? ?? 所有location都不能匹配后的默認匹配。

nginx-rewrite短域名跳轉
