nginx基本命令與配置

基本命令
 
 /usr/local/nginx/sbin/nginx -h #幫助 
/usr/local/nginx/sbin/nginx -v #顯示版本 
/usr/local/nginx/sbin/nginx -V #顯示版本和配置資訊 
/usr/local/nginx/sbin/nginx -t #測試配置 
-t:測試配置檔案是否正確,在執行時需要重新載入配置的時候,此命令非常重要,用來檢測所修改的配置檔案是否有語法錯誤。
例如我們要測試某個配置檔案是否書寫正確,我們可以使用以下命令: sbin/nginx – t – c conf/nginx2.conf
/usr/local/nginx/sbin/nginx -q #測試配置時,只輸出錯誤資訊 
/usr/local/nginx/sbin/nginx -s stop #停止伺服器 
/usr/local/nginx/sbin/nginx -s reload #重新載入配置 
/usr/local/nginx/sbin/nginx -s quit #不知道,估計和stop差不多 
/usr/local/nginx/sbin/nginx -s reopen #不知道,估計和reload類似 
/usr/local/nginx/sbin/nginx -p /nginx/path #預設為/usr/local/nginx(nginx安裝路徑),修改後影響log目錄和html目錄 
/usr/local/nginx/sbin/nginx -c /configure/file/path #配置檔案路徑,預設為conf/nginx.conf,有多個配置檔案時很有用,用這個可以啟動多個不同的nginx監聽不同埠 
/usr/local/nginx/sbin/nginx -g #沒用過
配置


配置檔案在 安裝目錄/conf/nginx.conf
修改完後用/usr/local/nginx/sbin/nginx -s reload重新載入
 
 #user nobody; #nginx啟動使用的使用者,配置fastcgi時,需要改為有許可權執行fastcgi的使用者 
worker_processes 1; #nginx啟動的程序數,1個已經足夠了 
#error_log logs/error.log; #nginx 錯誤日誌 相對於/usr/local/nginx/ 
#error_log logs/error.log notice; #nginx 記錄警告日誌 相對於/usr/local/nginx/ ,可改為logs/notice.log 
#error_log logs/error.log info; #nginx 記錄資訊日誌 相對於/usr/local/nginx/ ,可改為logs/info.log 
#pid logs/nginx.pid; #nginx程序檔案,最好不要改
