nginx 的 rewrite 設定

主要是因為 dokuwiki 原本使用的 apache 改成 nginx 之後遇到 rewrite 無法如預期的運作所進行的設定紀錄.

vi /etc/nginx/conf.d/default.conf

server {
  listen 80;
  server_name wiki.ichiayi.com www.ichiayi.com;
:
  index index.html index.htm index.php doku.php;
  access_log  /var/log/nginx/wiki.ichiayi.com/access.log;
  error_log  /var/log/nginx/wiki.ichiayi.com/error.log notice;
  #error_log  /var/log/nginx/wiki.ichiayi.com/error.log;
  rewrite_log on;
  root /var/www/html;
:

主要是在 error_log 後面增加 notice 以及增加 rewrite_log on

重新啟動 nginx 讓設定生效

systemctl restart nginx

開始觀察 nginx rewrite 運作紀錄

tail -f /var/log/nginx/wiki.ichiayi.com/error.log

可以透過 rewritten data: “/wiki/doku.php”, args: “id=tag/vmware” 這樣的資訊來判別是否與預期的設定相符

依照 nginx 網站針對 dokuwiki 的設定範例修改

vi /etc/nginx/conf.d/default.conf

server {
  listen 80;

  autoindex off;

  index index.html index.htm index.php doku.php;
  access_log  /var/log/nginx/wiki.ichiayi.com/access.log;
  #error_log  /var/log/nginx/wiki.ichiayi.com/error.log notice;
  error_log  /var/log/nginx/wiki.ichiayi.com/error.log;
  #rewrite_log on;
  root /var/www/html;
