centos7+python3.6+nginx1.12.2+django+uwsgi+postgresql搭建pythonweb

注意：需要先关闭selinux

安装python3.6

1、安装python需要的依赖

yum install openssl-devel bzip2-devel expat-devel gdbm-devel readline-devel sqlite-devel gcc-c++ zilb zlib-devel postgresql-devel*

2、备份centos7自带的python

[root@localhost bin]# cd /usr/bin/

[root@localhost bin]# mv python python.bak

3、创建python安装的目录，rz上传我本地的python安装包，也可在官网下载https://www.python.org/ftp/python/3.6.8/Python-3.6.8.tgz

[root@localhost usr]# mkdir -p /usr/local/python/python3

[root@localhost usr]# cd /usr/local/python/

[root@localhost python]# rz

4、解压下载好的安装包

[root@localhost python]#tar -zxvf Python-3.6.8.tgz

5、进入解压后的路径，编译到指定路径

[root@localhost Python-3.6.8]# pwd

/usr/local/python/Python-3.6.8

[root@localhost Python-3.6.8]# ./configure --prefix=/usr/local/python/python3

6、安装

[root@localhost Python-3.6.8]# make && make install

7、创建软连接，并检查python版本

[root@localhost bin]# cd /usr/bin/

[root@localhost bin]# ln -s /usr/local/python/python3/bin/python3 /usr/bin/python

[root@localhost bin]# python -V

Python 3.6.8

8、给pip创建软连接，并更新

[root@localhost bin]# cd /usr/bin/

[root@localhost bin]# ln -s /usr/local/python/python3/bin/pip3 /usr/bin/pip

[root@localhost bin]# pip install --upgrade pip

9、因为centos7的yum需要用到Python2.7，需要重新指定yum

[root@localhost bin]# vim /usr/bin/yum

将#!/usr/bin/python改成#!/usr/bin/python2.7

[root@localhost bin]# vim /usr/libexec/urlgrabber-ext-down

#!/usr/bin/python改成#!/usr/bin/python2.7

安装django和uwsgi

1、新建requirements.txt，写入如下内容，并安装django和一些项目需要的依赖包

[root@localhost python3]# vim requirements.txt

[root@localhost python3]# cat requirements.txt

django==1.11

psycopg2

psycopg2-binary

requests==2.21.0

uwsgi

[root@localhost python3]# pip install -r requirements.txt

2、修改pip的安装源（因为pip自带的安装源访问太慢）

修改 ~/.pip/pip.conf (没有就创建一个)，写入如下内容

[global]

timeout = 6000

index-url = http://pypi.douban.com/simple

trusted-host = pypi.douban.com

3、pip list #查看已安装的依赖包

[root@localhost python3]# pip list

Package Version

--------------- --------

certifi 2019.3.9

chardet 3.0.4

Django 1.11

idna 2.8

pip 19.2.3

psycopg2 2.7.7

psycopg2-binary 2.8.2

pytz 2019.1

requests 2.21.0

setuptools 40.6.2

sqlparse 0.3.0

urllib3 1.24.3

uWSGI 2.0.18

wheel 0.33.4

安装nginx

1、安装epel源

[root@localhost ~]# yum -y install epel-release

2、安装nginx

[root@localhost ~]# yum -y install nginx

3、开机自启

[root@localhost /]# systemctl start nginx

[root@localhost /]# systemctl enable nginx

安装postgresql

1、下载rpm包

wget https://download.postgresql.org/pub/repos/yum/10/redhat/rhel-7-x86_64/pgdg-centos10-10-2.noarch.rpm

2、解压

[root@localhost ~]# rpm -ivh pgdg-centos10-10-2.noarch.rpm

3、安装

[root@localhost ~]# yum -y install postgresql10-contrib postgresql10-server

4、初始化数据库，ok表示成功

[root@localhost ~]# /usr/pgsql-10/bin/postgresql-10-setup initdb

Initializing database ... OK

5、启动postgresql并设置开机自启

[root@localhost ~]# systemctl start postgresql-10 .service

[root@localhost ~]# systemctl enable postgresql-10.service

6、登录，切换到postgres用户（postgresql在安装时默认添加用户postgres），运行psql进入数据库

[root@localhost pgsql]# su - postgres

上一次登录：一 8月 26 13:10:26 CST 2019pts/0 上

-bash-4.2$ psql

psql (10.10)

输入 "help" 来获取帮助信息.

postgres=#

7、给postgres用户，设置密码

postgres=# ALTER USER postgres WITH PASSWORD '密码';

ALTER ROLE

8、退出数据库

postgres=# :\q

9、默认情况下postgresql是不用密码不支持远程登录的。我们需要修改配置文件

[root@localhost ~]# vim /var/lib/pgsql/10/data/pg_hba.conf

#修改后内容如下

10、修改远程访问，允许所有人，端口为3433

[root@localhost ~]# vim /var/lib/pgsql/10/data/postgresql.conf

#修改后内容如下

11、修改完成后，重启数据库

[root@localhost ~]# systemctl restart postgresql-10.service

uwsgi配置

[root@localhost ~]# vim /data1/captcha/captcha/uwsgi.ini

新建uwsgi.ini，写入如下内容

[uwsgi]

chdir = /data1/www/captcha.dachagui.com/captcha

socket = 127.0.0.1:8000

module = captcha.wsgi:application

processes = 2

master = 1

buffer-size = 88192

daemonize = /data1/log/uwsgi_log/uwsgi.log

pidfile = /data1/www/captcha.dachagui.com/captcha/uwsgi.pid

配置nginx

[root@localhost ~]# vim /etc/nginx

修改后内容如下

[root@localhost ~]# mkdir -p /etc/nginx/vhost

[root@localhost ~]# vim /etc/nginx/vhost/jango_test.conf

#写入内容如下

server{

listen 80; #监听80端口

server_name 127.0.0.1;

charset utf-8;

access_log /var/log/nginx/access.log; #日志文件位置

error_log /var/log/nginx/error.log;

client_max_body_size 75M;

location / { #访问/时

include uwsgi_params; #加载uwsgi模块

uwsgi_pass 127.0.0.1:8000; #将连接转到该IP

uwsgi_read_timeout 20;

}

}

保存后重启nginx

[root@localhost ~]# systemctl restart nginx

uwsgi启动django

[root@localhost captcha]# pwd

/data1/www/captcha.dachagui.com/captcha

[root@localhost captcha]# uwsgi --ini uwsgi.ini

[uWSGI] getting INI configuration from uwsgi.ini

成功访问到项目
