Nginx安装配置
1、安装nginx

yum -y
install
nginx

启动站点
1、启动nginx服务
/etc/init.d/nginx start (删除默认的default.conf配置)
2、启动uwsgi
/etc/init.d/cmdb start
排错：
1、在实际操作中发现，启动uwsgi服务后，访问站点出现“502 Bad Gateway”的报错，后来发现是在settings中设置了不允许访问站点
|
1
|
ALLOWED_HOSTS = []
|
改成
|
1
|
ALLOWED_HOSTS = [‘*’]
|
后问题解决。
2、由于python2.6 不支持django1.8 ，所以需要在服务器上安装python2.7，并且在安装之前，最好输入以下命令，将可能用到的包都装上，否则出现问题时，需要重新编译安装python2.7

yum -y

tk-devel gdbm-devel db4-devel libpcap-devel
yum -y
install
xz-devel libffi-devel
|
3、用pip安装uwsgi时，一定要用pip2.7(用python2.7安装的pip) 进行安装
4、invalid request block size: 4161 (max 4096)...skip报错解决
在访问站点时，出现了invalid request block size: 4161 (max 4096)...skip报错解决的报错。
解决办法是在uwsgi.ini配置文件中增加一条配置：buffer-size = 102400
将buffer-size设置大一些
