openssl

安装openssl1.1.1.f

wget ftp://ftp.fi.muni.cz/pub/openssl/source/openssl-1.1.1f.tar.gz

$ zxvf openssl-1.1.1f.tar.gz
$ cd openssl-1.1.1f/
$ ./config --prefix=/usr/local/openssl-1.1.1f

$ make && make install

2.检查结果

  $ cd /usr/local/openssl-1.1.1f/
  $ ldd bin/openssl
  	linux-vdso.so.1 =>  (0x00007ffc30ef0000)
  	libssl.so.1.1 => not found
  	libcrypto.so.1.1 => not found
  	libdl.so.2 => /lib64/libdl.so.2 (0x00007f3d29a58000)
  	libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f3d2983c000)
  	libc.so.6 => /lib64/libc.so.6 (0x00007f3d2946f000)
 /lib64/ld-linux-x86-64.so.2 (0x00007f3d29c5c000)
这个时候是不能运行的

$ ./bin/openssl version
  ./bin/openssl: error while loading shared libraries: libssl.so.1.1: cannot open shared object file: No such file or directory

修复错误

$ echo "/usr/local/openssl-1.1.1f/lib/" >> /etc/ld.so.conf

$ ldconfig -v

  $ mv /usr/bin/openssl /usr/bin/openssl.old
  $ ln -s /usr/local/openssl-1.1.1f/bin/openssl /usr/bin/openssl
  $ openssl version

./bin/openssl version

OpenSSL 1.1.1f 31 Mar 2020

*可以看看ldconfig命令的用途

uwsgi配置

编写uwsgi.ini文件：

[uwsgi]

master = true

http=127.0.0.1:5051

#socket=127.0.0.1:5000

pythonpath=/opt/myweb

chdir = /opt/myweb

wsgi-file=/opt/myweb/run.py

callable=app

processes=4

threads=2

buffer-size = 65536

vacuum=true

pidfile =/root/myweb/uwsgi.pid

其中/opt/myweb为你的程序路径

运行uwsgi:

uwsgi uwsgi.ini

测试一下服务端口：

flask + nginx + uWSGI部署

看一下服务是否正常：

写一个flask代码：run.py

from flask import Flask

app = Flask(__name__)

@app.route('/')

def hello_world():

return 'Hello, World!'

写一个测试脚本：test.py

import urllib.request

res=urllib.request.urlopen('http://127.0.0.1:5051/')

print(res.read())

运行后能打出helloworld:

flask + nginx + uWSGI部署

表示运行可以正常。

测试

显示internal error

一 .查看报错信息？

nginx 默认报错日志输出位置/var/log/nginx/error.log warn;

/04/20 13:59:35 [crit] 2409#2409: *7 connect() to 127.0.0.1:5000 failed (13: Permission denied) while connecting to upstream, client: 192.168.13.22, server: localhost, request: "GET / HTTP/1.1", upstream: "http://127.0.0.1:5000/", host: "10.22.32.63"

2020/04/20 14:00:48 [crit] 2409#2409: *11 connect() to 127.0.0.1:5000 failed (13: Permission denied) while connecting to upstream, client: 127.0.0.1, server: localhost, request: "GET / HTTP/1.1", upstream: "http://127.0.0.1:5000/", host: "localhost"

二 .处理思路

Linux命令行输入：# setsebool -P httpd_can_network_connect 1，执行成功后就对了
