gunicorn模块

1、安装gunicorn

[[email protected] ~]# yum search nginx
[[email protected] ~]# yum install -y nginx.x86_64
[[email protected] ~]# /etc/init.d/nginx restart
nginx: [warn] conflicting server name "112.65.140.132" on 0.0.0.0:80, ignored
停止 nginx：                                               [失败]
正在启动 nginx：nginx: [warn] conflicting server name "112.65.140.132" on 0.0.0.0:80, ignored
                                                           [确定]

2、测试nginx

3、安装gunicorn

[[email protected] ~]# pip install gunicorn

4、修改nginx的配置文件

[[email protected] simplecmdb]# vim /etc/nginx/conf.d/virtual.conf
# A virtual host using mix of IP-, name-, and port-based configuration
server {
    listen       112.65.140.133:8000;
    server_name  www.daixuan.com;

    location /static/admin {
        root   /opt/amos/lib/python2.7/lib/python2.7/site-packages/django/contrib/admin;
        index  index.html index.htm;
    }

    location / {
        proxy_pass http://localhost:8000;
    }
}

[[email protected] simplecmdb]# service nginx restart
nginx: [warn] conflicting server name "112.65.140.132" on 0.0.0.0:80, ignored
停止 nginx：                                               [确定]
正在启动 nginx：nginx: [warn] conflicting server name "112.65.140.132" on 0.0.0.0:80, ignored
                                                           [确定]

访问：http://112.65.140.133:8000/   返回502 

5、启用gunicorn

[[email protected] simplecmdb]# cd /opt/python/django/simplecmdb-gunicorn/
[[email protected] simplecmdb-gunicorn]# ls
112.65.140.132  exit  hostinfo  manage.py  nohup.out  simplecmdb  sysinformation-pickle.py

[[email protected] simplecmdb-gunicorn]# gunicorn simplecmdb.wsgi:application -D
Could not find platform independent libraries <prefix>
Could not find platform dependent libraries <exec_prefix>
Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>]
ImportError: No module named site
根据提示：安装site模块
[[email protected] simplecmdb-gunicorn]# pip install site
Collecting site

可以看到－D 指定的127.0.0.1上开启的端口

5、访问测试

 

这里css等文件被403了，所以肯定是用户权限问题。user从nginx修改为root，然后重启nginx即可。

[[email protected] simplecmdb-gunicorn]# vim /etc/nginx/nginx.conf
user root;
