django+uwsgi+nginx实现负载均衡

一、部署设备：

nginx服务器：192.168.110.128（转交设备）

uwsgi服务器：192.168.110.129/130/131（负载设备）

二、环境配置：

1、django环境（192.168.110.129/130/131）

#系统环境
yum install -y gcc-c++
yum install -y vim
yum update eple-release
#pip安装
yum install -y python3-pip
#python3安装
yum install -y python3
#虚拟环境安装
pip install virtualenv
pip isntall virtualenvwrapper
#配置虚拟环境
cd
vim ~/.bashrc
行末加入：
VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3
export WORKON_HOME=$HOME/.virtualenvs
source /usr/local/bin/virtualenvwrapper.sh
#立即生效
source ~/.bashrc
#创建虚拟环境：
mkvirtualenv dj_nginx
workon dj_nginx
pip install -r requirements.txt
#uwsgi安装：
yum install -y python-dev.x86-64
pip isntall uwsgi
#搜集静态文件
python manage.py collectstatic
#关闭防火墙
systemctl stop firewalld

 2、uwsgi.ini配置（192.168.110.129/130/131）

[uwsgi]
#使用nginx连接时使用
socket=192.168.110.129:8082
#直接做web服务器使用
http=192.168.10.129:8080
#项目目录
chdir=/home/xxx
#项目中wsgi.py文件的目录，相对于项目目录
wsgi-file=xxx/wsgi.py
processes=8
threads=16
buffer-size = 65536*1024*1024*1024
master=True
pidfile=uwsgi.pid
daemonize=uwsgi.log
virtualenv=/root/.virtualenvs/xxx

3、nginx.conf配置（192.168.110.128）

#user  nobody;
worker_processes  8;
worker_rlimit_nofile 65535;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
    worker_connections  65535;
    use epoll;
    multi_accept on;
}

http {
    include       mime.types;
    default_type  application/octet-stream;

    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
    #                  '$status $body_bytes_sent "$http_referer" '
    #                  '"$http_user_agent" "$http_x_forwarded_for"';

    #access_log  logs/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;

    upstream monitor {
        server 192.168.110.128:8082;
        server 192.168.110.129:8082;
        server 192.168.110.130:8082;
        server 192.168.110.131:8082;
    }

    server {
            listen       8080;
            server_name  localhost;

            location /{
                include uwsgi_params;
                uwsgi_pass monitor;
            }

            location /static{
                alias /var/www/monitor/static;
            }

            error_page   500 502 503 504  /50x.html;
            location = /50x.html {
            root   html;
            }
    }
}
