1. 安装相关工具和依赖

[root@uwsgi ~]# yum -y install git wget httpd vim # 安装相关工具
[root@uwsgi ~]# yum -y install gcc zlib* openssl-devel # 安装编译工具和依赖库

2. 安装 Python 环境

rhel系列没法经过yum直接安装python3，须要源码编译安装

[root@uwsgi ~]# pwd # 查看当前目录
/root
[root@uwsgi ~]# wget https://www.python.org/ftp/python/3.6.5/Python-3.6.5.tgz # 下载python3.6.5
[root@uwsgi ~]# tar -zxvf Python-3.6.5.tgz # 解压
[root@uwsgi ~]# cd Python-3.6.5

[root@uwsgi Python-3.6.5]# pwd # 查看当前目录
/root/Python-3.6.5
[root@uwsgi Python-3.6.5]# ./configure # 编译
[root@uwsgi Python-3.6.5]# make && make install # 安装
[root@uwsgi Python-3.6.5]# which python3 # 查看python3的路径
/usr/local/bin/python3

4. 安装 uWSGI

[root@uwsgi ~]# python3 -m pip install uwsgi

5. 安装配置虚拟环境

[root@uwsgi ~]# python3 -m pip install virtualenv # 安装虚拟环境
[root@uwsgi ~]# virtualenv -p /usr/local/bin/python3 /venv # 配置虚拟环境
[root@uwsgi ~]# source /venv/bin/activate # 激活虚拟环境
(venv) [root@uwsgi ~]# pip install -r /root/demo/requirements.txt # 安装项目依赖
(venv) [root@uwsgi ~]# pip freeze # 查看依赖库是否安装
(venv) [root@uwsgi ~]# deactivate # 取消激活虚拟环境
[root@uwsgi ~]#

6. 修改 ALLOW_HOSTS

[root@uwsgi ~]# vim demo/demo/settings.py # 编辑项目中的 settings.py

ALLOWED_HOSTS = ["192.168.41.130",]

5. 配置 uWSGI

[root@uwsgi ~]# mkdir -p /var/log/uwsgi # 建立 uwsgi 的日志目录
[root@uwsgi ~]# vim /etc/uwsgi.ini # 建立 uwsgi.ini 配置文件

[uwsgi]
chdir=/root/demo
http=192.168.41.130:8000
home=/venv
module=demo.wsgi:application
master=True
pidfile=/tmp/demo.pid
max-requests=5000
daemonize=/var/log/uwsgi/demo.log
env=LANG=en_US.UTF-8
buffer-size=32768

6. 启动 uWSGI

[root@uwsgi ~]# uwsgi --init /etc/uwsgi.ini # 以 /etc/uwsgi.ini 配置启动 uwsgi

7. 注意事项

未安装zlib*：

zipimport.ZipImportError: can't decompress data; zlib not available # 编译时报错

未安装openssl、openssl-devel：

pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available # pip 安装 uwsgi 时报错

uwsgi 没法访问，日志报错：

invalid request block size: 21573 (max 4096)...skip # 在 /etc/uwsgi.ini 中添加 buffer-size=32768
