常見的condition
-
變量名（變量值爲空串，或者以“0”開始，則爲false，其他的均爲true）
-
以變量爲操作構成的比較表述式（可使用=，!=類似的比較操作符）
- 正則表達式的模式匹配操作
- ~：區分大小寫的模式匹配檢查
- ~*：不區分大小寫的模式匹配檢查
- !~ 和!~*:對上面兩種測試取反
- 測試指定路徑爲文件的可能性（-f，!-f）
- 測試指定路徑爲目錄的可能性（-d，!-d）
- 測試文件的存在性（-e，!e）
- 檢查文件是否有執行權限（-x，!x）
基於瀏覽器實現分離案例
除了谷歌瀏覽器以外都不可以訪問
編輯配置文件：
[root@linfan ~]# vim /usr/local/nginx/conf/nginx.conf
...
...
location / {
root html;
index index.html index.htm;
}
//添加以下內容
location /images {
if ($http_user_agent ~ Chrome) {
rewrite ^/images/(.*)$ /chrome/doudou/$1 break;
}
}
...
...創建在網站存放根目錄下面創建/chrome以及chrome/doudou/目錄並在chrome/doudou/上傳一張圖片
root@linfan html]# mkdir -p chrome/doudou/
[root@linfan html]# ls
50x.html chrome index.html
[root@linfan html]# cd chrome/
[root@linfan chrome]# ls
doudou
[root@linfan chrome]# cd doudou/
[root@linfan doudou]# ls
1.png驗證:
在谷歌瀏覽器上輸入http://192.168.24.148/images/1.png
可以正常訪問
在其他瀏覽器上輸入http://192.168.24.148/images/1.png
無法訪問
防盜鏈案例
location ~* \.(jpg|gif|jpeg|png)$ {
valid_referer none clocked www.idfsoft.com;
if ($invalid_referer) {
rewrite ^/ http://www.idfsoft.com/403.html;
}
}反向代理與負載均衡
nginx通常被用作後端服務器的反向代理，這樣就可以很方便的實現動靜分離以及負載均很，從而大大提高服務器的處理能力。
在upstream段內，定義一個服務器列表，默認的方式是輪詢，如果要確定同一訪問者發出的請求總是由同一個後端服務器來處理，可以設置ip_hash
開啓另外的二臺服務器
IP地址爲 192，168.24.131
和192.168.24.146 並在服務器裏面配置httpd
[root@linfan ~]# setenforce 0
setenforce: SELinux is disabled
[root@linfan ~]# sed -ri 's/^(SELINUX=).*/\1disabled/g' /etc/selinux/config
[root@linfan ~]# systemctl stop firewalld
[root@linfan ~]# systemctl disable firewalld
[root@linfan ~]# cd /etc/yum.repos.d/
[root@linfan yum.repos.d]# ls
163.repo
[root@linfan yum.repos.d]# cd
[root@linfan ~]# yum -y install httpd
