python的环境以前搭过，到博客找了一下没有。做过的东西要记录很重要的。不然就是浪费时间。
对于gunicorn和uwsgi的选择，主要看个人喜好。gunicorn配置简单点。但是如果用nginx的话，用uwsgi好一点，nginx兼容了uwsgi。
1，安装依赖
# yum install nginx python2-pip python-devel gcc openssl-devel libyaml-devel libffi-devel \ readline-devel zlib-devel gdbm-devel ncurses-devel gcc-c++ automake autoconf mysql-devel
错误1，
Running setup.py install for uwsgi ... error
Complete output from command /usr/bin/python2 -u -c "import setuptools, tokenize;__file__='/tmp/pip-build-N7CH0N/uwsgi/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-XWtx7A-record/install-record.txt --single-version-externally-managed --compile:

错误2：

ERROR: sh: mysql_config: 未找到命令

libs = mysql_config("libs_r")
File "setup_posix.py", line 25, in mysql_config
raise EnvironmentError("%s not found" % (mysql_config.path,))
EnvironmentError: mysql_config not found
缺少mysql开发依赖
2，安装uwsgi，django
# pip install uwsgi mysql-connector-python protobuf psutil pytz qrcode virtualenv \ websocket-client wheel web.py mysql-python django-cors-headers greenlet image "django<2"
根据需要，安装扩展。主要依据是代码用到哪些扩展。
3，测试uwsgi
# cat test.py
def application(env, start_response):
start_response('200 OK', [('Content-Type','text/html')])
return ["Hello World"]
# uwsgi --http :8000 --wsgi-file test.py
通过8000端口访问一下，出现Hello World，说明成功了
4，创建django项目根目录，创建启动脚本
# cat test.ini [uwsgi] http = :19090 //直接访问 socket = 127.0.0.1:19091 //反代用 wsgi-file = /var/www/mysite/wsgi.py master = true processes = 4 threads = 2 stats = 127.0.0.1:9191 //监控用
5，安装uwsgitop
# pip install --upgrade pip //升级pip # pip install setuptools -U //升级setuptoos # pip install "uwsgitop==0.11"
要安装uwsgitop，setuptools的版本>=20.2.2
Collecting uwsgitop

Complete output from command python setup.py egg_info:
error in uwsgitop setup command: 'install_requires' must be a string or list of strings containing valid project/version requirement specifiers

Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-QbKKdJ/uwsgitop/
You are using pip version 8.1.2, however version 19.1.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
碰到这样的问题就该升级了。
# uwsgitop 127.0.0.1:9191 uwsgi-2.0.18 - Mon May 20 10:15:31 2019 - req: 0 - RPS: 0 - lq: 0 - tx: 0 node: 127.0.0.1 - cwd: /var/www/mysite - uid: 0 - gid: 0 - masterpid: 9247 WID % PID REQ RPS EXC SIG STATUS AVG RSS VSZ TX ReSpwn HC RunT LastSpwn 1 0.0 9252 0 0 0 0 idle 0ms 0 0 0 1 0 0 10:15:07 2 0.0 9254 0 0 0 0 idle 0ms 0 0 0 1 0 0 10:15:07 3 0.0 9256 0 0 0 0 idle 0ms 0 0 0 1 0 0 10:15:07 4 0.0 9258 0 0 0 0 idle 0ms 0 0 0 1 0 0 10:15:07
6，nginx 反代
server {
listen 80;
server_name tank.51yip.com;
location / {
try_files $uri @test;
}
location @test {
include uwsgi_params;
uwsgi_pass 127.0.0.1:19091;
}
access_log /var/log/nginx/test.access.log;
error_log /var/log/nginx/test.error.log;
}
systemctl start nginx && systemctl enable nginx，启动nginx和开机启动nginx
7，systemctl自启动uwsgi
# cat /usr/lib/systemd/system/test.service [Unit] Description=test After=syslog.target [Service] ExecStart=/usr/bin/uwsgi --ini /var/www/mysite/test.ini Restart=always KillSignal=SIGQUIT Type=notify StandardError=syslog NotifyAccess=all [Install] WantedBy=multi-user.target
systemctl start test && systemctl enable test，启动uwsgi和开机启动uwsgi
# netstat -tpnl |grep uwsgi tcp 0 0 0.0.0.0:19090 0.0.0.0:* LISTEN 10520/uwsgi tcp 0 0 127.0.0.1:19091 0.0.0.0:* LISTEN 10520/uwsgi tcp 0 0 127.0.0.1:9191 0.0.0.0:* LISTEN 10520/uwsgi
