最近學習nginx先拿windos練練手,稍微有些積累記錄下
1. 先去網上下載nginx後解壓,我這邊放到F:nginx下了;
2. 點擊nginx目錄下想nginx.exe按照,閃了一下;
3. 打開瀏覽器,輸入localhost看看是否有welcome to nginx字樣;或是打開任務管理器,進程中是否有nginx.exe或是打開 nginx的安裝目錄看logs下面的error.log大小是否是0kb;
4. 如果能正常啓動則繼續,如果啓動不了看看error.log提示內容是什麼; 因爲nginx默認監聽80端口,可能會出現端口占用的情況, 改下conf中的nginx.conf文件就好,在
http{
server{
listen 8077; # 監聽8077端口
}
}下面會介紹;我在啓動的時候,因爲安裝了php,所以發生了端口占用這樣的事情;
5. 因爲是測試本地的服務,所以修改hosts,新增 127.0.0.1 a.com;
6. 我在本地和外網準備了2臺服務器;
7. 修改修改下tomcat的server.xml文件,除了配置端口等外,在
<Host> <Context path="" docBase="/zjlm.client.web" reloadable="true"/> </Host>
8. 完整的nginx.conf文件內容是
#user nobody;
worker_processes 1;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid;

9. 需要注意的事情, 一開始配置完靜態文件不能訪問,靜態資源路徑不對, 需要把靜態資源拷到nginx目錄下,然後配置root 文件目錄;
10. 訪問a.com:8077查看情況
11. #注* server段 proxy_pass定義的a.com需要跟upstream 裏面定義的a.com一致，否則server找不到均衡。
12. #配置Nginx動靜分離
location ~ .*\.(html|htm|gif|jpg|jpeg|bmp|png|ico|txt|js|css)$ {
root F:/nginx/nginx/nginx/html;
}
13. #expires定義用戶瀏覽器緩存的時間爲3天，如果靜態頁面不常更新，可以設置更長，這樣可以節省帶寬和緩解服務器的壓力
expires 3d;
14. 開啓nginx的監控
nginx簡單狀態監控,在nginx.conf中添加如下代碼即可監控nginx當前的狀態，然後訪問http://serverip/status即可訪問
location /status {
stub_status on;
access_log off;
}
一般顯示爲
Active connections: 16
server accepts handled requests
191226 191226 305915
Reading: 0 Writing: 1 Waiting: 15
ctive connections: 對後端發起的活動連接數.
Server accepts handled requests: Nginx總共處理了24個連接,成功創建24次握手(證明中間沒有失敗的),總共處理了129個請求.
Reading: Nginx 讀取到客戶端的Header信息數.
Writing: Nginx 返回給客戶端的Header信息數.
Waiting: 開啓keep-alive的情況下,這個值等於 active – (reading + writing),意思就是Nginx已經處理完成,正在等候下一次請求指令的駐留連接.
注意的，本模塊默認是不會編譯進Nginx的,如果你要使用該模塊,則要在編譯安裝Nginx時指定:
