升级pip

因为python3.5自带pip，setuptools

/usr/python3./bin/pip3 install --upgrade pip

ln -s /usr/python3./bin/pip3 /usr/bin/pip3

centos下安装pip时失败：

[root@wfm ~]# yum -y install pip
Loaded plugins: fastestmirror, refresh-packagekit, security

Setting up Install Process
No package pip available.
Error: Nothing to do

解决方法：

　　

需要先安装扩展源EPEL。

EPEL(http://fedoraproject.org/wiki/EPEL) 是由 Fedora 社区打造，为 RHEL 及衍生发行版如 CentOS、Scientific Linux 等提供高质量软件包的项目。

首先安装epel扩展源：

sudo yum -y install epel-release

然后再安装pip

一、安装httpd服务

apache在centos7中是Apache HTTP server。如下对httpd的解释就是Apache HTTP Server。所以想安装apache其实是要安装httpd。

httpd.x86_64 : Apache HTTP Server

安装：

# yum install httpd

设置httpd服务开机启动

[root@yl-web httpd]# /sbin/chkconfig httpd on
Note: Forwarding request to 'systemctl enable httpd.service'.
ln -s '/usr/lib/systemd/system/httpd.service' '/etc/systemd/system/multi-user.target.wants/httpd.service'

启动httpd服务

[root@yl-web httpd]# /sbin/service httpd start
Redirecting to /bin/systemctl start  httpd.service

访问ip验证一下，成功！

二、配置

httpd默认的配置文件目录为

[root@yl-web httpd]# cd /etc/httpd/
[root@yl-web httpd]# ls
conf  conf.d  conf.modules.d  logs  modules  run

主配置文件是/etc/httpd/conf/httpd.conf。

配置存储在的/etc/httpd/conf.d/目录。

1、主配置文件

看一下主配置文件httpd.conf里有用的配置项

#服务器根目录
ServerRoot "/etc/httpd"

#端口
#Listen 12.34.56.78:80
Listen 80

#域名+端口来标识服务器，没有域名用ip也可以
#ServerName www.example.com:80

#不许访问根目录
<Directory />
    AllowOverride none
    Require all denied
</Directory>

# 文档目录
DocumentRoot "/var/www/html"

# 对 /var/www目录访问限制
<Directory "/var/www">
    AllowOverride None
    # Allow open access:
    Require all granted
</Directory>

# 对/var/www/html目录访问限制
<Directory "/var/www/html">
　　 Options Indexes FollowSymLinks
　　 AllowOverride None
 　　Require all granted
</Directory>

# 默认编码
AddDefaultCharset UTF-8

#EnableMMAP off
EnableSendfile on
# include进来其它配置文件

IncludeOptional conf.d/*.conf

2、下载配置mod_wsgi

安装mod_wsgi前先进行apache的apxs扩展

http-devel 是为了apxs,yum后你可以whereis apxs去寻找他，然后后边编译使用。

# yum install -y httpd-devel

下载

[root@yl-web collectedstatic]# yum install mod_wsgi

在httpd.conf中增加下面配置：

LoadModule  wsgi_module modules/mod_wsgi.so

该配置用来连接django.wsgi，使工程被apache加载。

配置django wsgi

在项目目录下新建wsgi，里面新建django.wsgi，内容如下

import os
import sys
import django.core.handlers.wsgi
from django.conf import settings

# Add this file path to sys.path in order to import settings
sys.path.insert(0, os.path.join(os.path.dirname(os.path.realpath(__file__)), '..'))

os.environ['DJANGO_SETTINGS_MODULE'] = 'lxyproject.settings'

sys.stdout = sys.stderr

DEBUG = True

application = django.core.handlers.wsgi.WSGIHandler()

配置wsgi时，

• 必须配置项目路径到系统路径中,因为要通过项目路径找到settings.py配置文件。也就是sys.path.insert(0, os.path.join(os.path.dirname(os.path.realpath(__file__)), '..'))。
• DJANGO_SETTINGS_MODULE必须指向项目的settings.py文件。

修改了wsgi的配置后必须重启httpd服务。

3、配置django项目虚拟主机

在/etc/httpd/conf.d中添加配置文件lxyproject.conf，内容如下

<VirtualHost *:80>

WSGIScriptAlias / /srv/lxyproject/wsgi/django.wsgi
Alias /static/ /srv/lxyproject/collectedstatic/

ServerName 10.1.101.31
#ServerName example.com
#ServerAlias www.example.com

<Directory /srv/lxyproject/collectedstatic>
    Options Indexes  FollowSymLinks
    AllowOverride None
    Require all granted
</Directory>

<Directory /srv/lxyproject/wsgi/>
    Require all granted
</Directory>
ErrorLog   /etc/httpd/logs/lxyproject.error.log
LogLevel warn
</VirtualHost>

其中

• WSGIScriptAlias 直接告诉apache，这个虚拟主机中，请求/就交给WSGI处理，也就是项目中配置的django.wsgi会指明。

• Alias 说明访问/static/直接从DocumentRoot中获取，而无需经过WSGI处理。

现在就可以通过apache服务器配置的IP访问django项目了。

django安装mysqlclient组件遇到的问题：

centos7 解决 Python.h：没有那个文件或目录 错误的方法

sudo yum install python-devel

/usr/python3./bin/pip3 install --upgrade pip

ln -s /usr/python3./bin/pip3 /usr/bin/pip3

ln -s /usr/python3./lib/python3./site-packages/django/bin/django-admin.py    /usr/bin/django-admin.py

ln -s /usr/python3./bin/python3. /usr/bin/python

ln -s /usr/python3./bin/pip3 /usr/bin/pip3

安装mysqlclient报错：
