從Windows下的Apache轉(zhuǎn)移到Linux下的Nginx，發(fā)現(xiàn)有很多坑需要踩。
以下就做個(gè)簡(jiǎn)單的記錄，方便后來(lái)者爬坑。

配置Nginx，一般會(huì)遇到以下幾個(gè)坑：

配置pathinfo模式

在server（也就是你的站點(diǎn)，一個(gè)server對(duì)應(yīng)一個(gè)站點(diǎn)）中輸入以下內(nèi)容：

location ~ ^(.+/.php)(.*)$ { root html/[站點(diǎn)目錄](méi); #配置站點(diǎn)目錄路徑 fastcgi_split_path_info ^(.+/.php)(.*)$; fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock; fastcgi_index index.php; include fastcgi_params; fastcgi_param SCRIPT_FILENAME $document_root/$fastcgi_script_name; fastcgi_param PATH_INFO $fastcgi_script_name;}

其中root html/[站點(diǎn)目錄](méi)這個(gè)一定要填寫(xiě)跟你server的站點(diǎn)目錄路徑，要不它默認(rèn)為html，從而導(dǎo)致路徑解析失敗。會(huì)出現(xiàn)的現(xiàn)象就是，在之前配置的location中定義了root路徑也無(wú)法生效,訪(fǎng)問(wèn)http://localhost會(huì)跳轉(zhuǎn)到/usr/local/nginx/html/index.php[index.html],因?yàn)槲业膎ginx是源碼安裝，所以路徑可能不同，yum安裝的話(huà)一般會(huì)在/usr/share/nginx/html/index.php[index.html].(PS：原默認(rèn)關(guān)于fastcgi的配置可以注釋掉)

隱藏index.php

隱藏index.php，大多數(shù)是采用Nginx的重寫(xiě)規(guī)則來(lái)進(jìn)行的。
下面，就是博主的列出的一個(gè)參考：

location / { root html/[站點(diǎn)目錄](méi); index index.php; if (!-e $request_filename) {  rewrite ^(.*)$ /index.php/$1; }}

這里的站點(diǎn)目錄是你程序（框架）的index.php所在的目錄。例如，CI框架的話(huà)，root html/ci，其中index.php位于html/ci/index.php.

本質(zhì)上，隱藏index.php文件就是重寫(xiě)URL。具體詳細(xì)用法可以參考Nginx重寫(xiě)模塊的官方文檔：Module ngx_http_rewrite_module

同一服務(wù)器多站點(diǎn)配置

一般一臺(tái)服務(wù)器不會(huì)單一的運(yùn)行一個(gè)站點(diǎn)，往往是運(yùn)行多個(gè)站點(diǎn)的。

在Nginx配置多站點(diǎn)是非常簡(jiǎn)單，便捷的。正如，前面所說(shuō)的，一個(gè)server對(duì)應(yīng)一個(gè)站點(diǎn)。例如：

server { listen 80; server_name www.leslie.net.cn; location / { .... }}server { listen 80; server_name www.hellomyfrend.top; location / { .... }}

這樣，就配置了兩個(gè)站點(diǎn)，分別為www.leslie.net.cn和www.hellomyfrend.top.

這里貼一份配置文件作為參考：
