Nginx訪問日志

日志不記錄靜態(tài)文件

日志切割

?域名重定向

配置第二個域名：

vi /etc/nginx/conf.d/blog.aminglinux.cc.conf 在 server_name 那一行的域名后面再加一個域名，空格作為分隔。 nginx -t nginx -s reload

?

域名重定向： #通過設(shè)置Web服務(wù)的配置文件，將原本訪問A域名的請求訪問到B域名

從a域名跳轉(zhuǎn)到b域名 vi /etc/nginx/conf.d/blog.aminglinux.cc.conf //增加：if ( $host = blog.aminglinux.cc ){rewrite /(.*) http://www.aming.com/$1 permanent;} nginx -t nginx -s reload

測試是否實(shí)現(xiàn)了重定向：

curl -x127.0.0.1:80 -I blog.aminglinuc.cc/1.txt

補(bǔ)充：

狀態(tài)碼：200（OK） 404（不存在） 304（緩存） 301（永久重定向） 302 （臨時重定向） #301 permanent 302 redirect如果是域名跳轉(zhuǎn)，用301； 如果不涉及域名跳轉(zhuǎn)用302 rewrite /1.txt /2.txt redirect;

?效果圖：

用戶認(rèn)證

為了站點(diǎn)的安全，可以通過修改配置文件來針對一些重要的目錄（站點(diǎn)后臺地址）進(jìn)行用戶認(rèn)證

用戶認(rèn)證的目的：

實(shí)現(xiàn)二次認(rèn)證，針對一些重要的目錄（后臺地址）

配置用戶認(rèn)證：

vi 配置文件 //添加：location ~ admin.php { auth_basic "Auth"; auth_basic_user_file /etc/nginx/user_passwd; fastcgi_pass 127.0.0.1:9000;fastcgi_index index.php;fastcgi_param SCRIPT_FILENAME /data/wwwroot/bbs.aminglinux.cc$fastcgi_script_name;include fastcgi_params; }

補(bǔ)充：

nginx location優(yōu)先級：

location / 優(yōu)先級比 location ~ 要低，也就是說，如果一個請求（如，aming.php）同時滿足兩個location location /amin.php location ~ *.php$ 會選擇下面的 nginx location 文檔： https://github.com/aminglinux/nginx/tree/master/location

Nginx訪問日志

• 日志的內(nèi)容是通過編輯Nginx主配置文件來定義的。?
• 日志的格式（顯示在日志文件中的內(nèi)容）

log_format main '$remote_addr - $remote_user [$time_local] "$request" ''$status $body_bytes_sent "$http_referer" ''"$http_user_agent" "$http_x_forwarded_for"';

• $remote_addr 客戶端ip（公網(wǎng)ip）
• $http_x_forwarded_for 代理服務(wù)器ip
• $time_local 服務(wù)器本地時間
• $host 訪問主機(jī)名（域名）
• $request_uri 訪問的url地址
• $status 狀態(tài)碼
• $http_referer 從哪個站點(diǎn)跳轉(zhuǎn)到該站點(diǎn)的（直接訪問該項(xiàng)為-）
• $http_user_agent 訪問方式（通過XX瀏覽器，或curl方式訪問）

自定義一個格式的日志test

• 為了試驗(yàn)效果，我們可以自定義一個日志格式，只記錄客戶端ip和狀態(tài)碼的日志格式test ，然后把這個格式應(yīng)用到www.lcblog.com上去。

log_format test '$remote_addr $status' ;

• 應(yīng)用到blog.abc.com.conf中

access_log /var/log/nginx/host.access.log test;

• 日志中只會記錄如下，客戶端ip和狀態(tài)碼的信息。

[root@localhost blog.abc.com]# cat /var/log/nginx/host.access.log 192.168.254.1 200 127.0.0.1 301 nginx內(nèi)置變量： https://github.com/aminglinux/nginx/blob/master/rewrite/variable.md

在網(wǎng)頁上刷新也會在日志上產(chǎn)生文件

日志不記錄靜態(tài)文件

• 一個網(wǎng)站里可能包含很多靜態(tài)文件，比如jpg,png,gif,js,css等，如果每一個訪問都記錄日志的話，日志文件會瘋狂增長，這就需要配置靜態(tài)文件不記錄日志了，在虛擬主機(jī)配置文件中添加如下內(nèi)容。

location ~* \.(png|jpeg|gif|js|css|bmp|flv)$ #*表示不區(qū)分大小寫{access_log off;}

補(bǔ)充：

• tail -f /data/logs/bbs.access.log ? ? ?-f選型可以動態(tài)查看一個文件的內(nèi)容

• ">"可以清空一個文件內(nèi)容

• ~* 表示不區(qū)分大小寫的匹配 后面跟正則表達(dá)式.表示任意一個字符 #不使用正則表達(dá)式的含義，就使用脫義?

日志切割

• 系統(tǒng)自帶日志切割工具logrotate。配置文件是/etc/logratate.conf,子配置文件/etc/lograte.d/* ?
• nginx 的日志切割配置文件/etc/logrotate.d/nginx ? ?#yum安裝的nginx，自帶了切割文件

/var/log/nginx/*.log {dailydateextmissingokrotate 52compressdelaycompressnotifemptycreate 640 nginx admsharedscriptspostrotateif [ -f /var/run/nginx.pid ]; thenkill -USR1 `cat /var/run/nginx.pid`fiendscript

• 測試執(zhí)行l(wèi)ogrotate -vf /etc/logrotate.d/nginx ? #-f ?強(qiáng)制切割
