環境：
django：1.8.16 ?
python：2.7.13
pip：2.7
uwsgi：2.0.15

Uwsgi的安裝配置
1、安裝python2.7 （省略安裝過程）
2、安裝pip2.7 （省略安裝過程）
3、安裝uwsgi（注意：要用pip2.7安裝）
| 1 2 3 | pip2.7?install?uwsgi pip2.7?install?requests ln?-s?/usr/local/python2.7/bin/uwsgi?/usr/bin/uwsgi |
4、配置uwsgi.ini?
路徑： /opt/cmdb/uwsgi.ini
文件內容：
[root@localhost cmdb]# cat uwsgi.ini?
| 1 2 3 4 5 6 7 8 9 10 11 | [uwsgi]socket?=?127.0.0.1:8088chdir=/opt/cmdb wsgi-file?=?cmdb/wsgi.py pidfile?=?/var/run/uwsgi.pid daemonize?=?/var/log/uwsgi.log perl-auto-reload?=?2#buffer-size?=?102400master?=?true processes?=?2threads?=?4 |
Uwsgi：常用參數和選項
關于參數的具體使用，可以閱讀官方文檔http://uwsgi-docs.readthedocs.org/en/latest/Options.html?，在這里列出一些常用的參數：
-
chdir 項目目錄
-
home virtualenv目錄（如沒有運行virtualenv虛擬環境，則無需設置）
-
socket 套接字文件或TCP套接字，例如：site1.uwsgi.sock 或 127.0.0.1:8000
-
uid 用戶id
-
gid 用戶組id
-
processes 工作進程數
-
harakiri 進程超過該時間未響應就重啟該進程（默認單位為秒）
-
module 要啟動的wsgi模塊入口，如：mysite.wsgi:application
-
ini 指定ini配置文件
-
xml 指定xml配置文件（與ini類似）
-
file 指定要運行的wsgi程序文件，如：test.py
-
emperor Emperor模式
-
so-keepalive 開啟TCP KEEPALIVE（unix套接字方式下無效）
uwsgi服務init腳本 /etc/init.d/cmdb

Nginx安裝配置
1、安裝nginx
| 1 | yum?-y?install?nginx |
2、配置nginx
[root@localhost cmdb]# cat /etc/nginx/conf.d/cmdb.conf?
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 | upstream?django?{????server?127.0.0.1:8088; ????} server?{????listen??????80; ????server_name?172.16.42.128; ????charset?????utf-8; ????client_max_body_size?10M; ????location?/static?{ ????????alias?/opt/cmdb/static; ????} ????location?/?{ ????????uwsgi_send_timeout?300; ????????uwsgi_connect_timeout?300; ????????uwsgi_read_timeout?300; ????????uwsgi_pass??django; ????????include?????/etc/nginx/uwsgi_params; ????} } |
啟動站點
1、啟動nginx服務
/etc/init.d/nginx start (刪除默認的default.conf配置)
2、啟動uwsgi
/etc/init.d/cmdb start
排錯：
1、在實際操作中發現，啟動uwsgi服務后，訪問站點出現“502 Bad Gateway”的報錯，后來發現是在settings中設置了不允許訪問站點
| 1 | ALLOWED_HOSTS?=?[] |
改成
| 1 | ALLOWED_HOSTS?=?[‘*’] |
后問題解決。
2、由于python2.6 不支持django1.8 ，所以需要在服務器上安裝python2.7，并且在安裝之前，最好輸入以下命令，將可能用到的包都裝上，否則出現問題時，需要重新編譯安裝python2.7
| 1 2 3 4 | yum?-y?install?zlib-devel?bzip2-devel?openssl-devel? yum?-y?install?ncurses-devel?sqlite-devel?readline-devel? yum?-y?install?tk-devel?gdbm-devel?db4-devel?libpcap-devel yum?-y?install?xz-devel?libffi-devel |
3、用pip安裝uwsgi時，一定要用pip2.7(用python2.7安裝的pip) 進行安裝
4、invalid request block size: 4161 (max 4096)...skip報錯解決
在訪問站點時，出現了invalid request block size: 4161 (max 4096)...skip報錯解決的報錯。
解決辦法是在uwsgi.ini配置文件中增加一條配置：buffer-size = 102400
將buffer-size設置大一些
