1.安装python3.5可能使用的依赖
yum install openssl-devel bzip2-devel expat-devel gdbm-devel readline-devel sqlite-devel
或者
yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make
wget https://www.python.org/ftp/python/3.5.1/Python-3.5.1.tgz
tar -zxvf Python-3.5.1.tgz
把python移到/usr/local下面
mv Python-3.5.1 /usr/local
删除旧版本的python依赖
ll /usr/bin | grep python
rm -rf /usr/bin/python
进入python目录
cd /usr/local/Python-3.5.1/
•配置
./configure
编译
make
编译，安装 
make install
删除旧的软链接，创建新的软链接到最新的python
rm -rf /usr/bin/python
ln -s /usr/local/bin/python3.5 /usr/bin/python
python -V
 
2.把默认python改成了python3的版本后，yum无法使用

既然把默认python改成了python3的版本，那么这时候yum就出问题了，因为yum貌似不支持python3，开发了这个命令的老哥也不打算继续写支持python3的版本了，
所以，如果和python版本相关的文件就不要通过yum下载了，这里我们需要把yum默认的指向改为python2.7的版本，
分别是两个文件，使用vi打开，输入i进行修改，修改完之后按esc键，然后输入":wq"，这就完成了修改并保存
  vi /usr/libexec/urlgrabber-ext-down
 vi /usr/bin/yum
这样我们就完成了新安装的centos系统中的两个python版本的全部流程。
在小黑框中输入python2则调起python2，输入python，则默认调起python3，pip2调起python2下的pip，pip调起python下的pip。
 
 
1.CentOS7安装图解
https://www.osyunwei.com/archives/7829.html2.CentOS 7下安装Python3.5

yum -y install zlib zlib-devel openssl openssl--devel pcre pcre-devel
yum install openssl-devel bzip2-devel expat-devel gdbm-devel readline-devel sqlite-devel
wget https://www.python.org/ftp/python/3.5.1/Python-3.5.1.tgz 或者 后面加上--no-check-certificate
tar -zxvf Python-3.5.1.tgz
把python移到/usr/local下面
mv Python-3.5.1 /usr/local
删除旧版本的python依赖
ll /usr/bin | grep python
rm -rf /usr/bin/python
cd /usr/local/Python-3.5.1/
./configure
make -j6
make install
删除旧的软链接，创建新的软链接到最新的python
rm -rf /usr/bin/python
ln -s /usr/local/bin/python3.5 /usr/bin/python
python -V
cd /opt

解决方法 安装 pip3 install Django==1.11.1
然而又出现下面 ImportError: cannot import name patterns
vim touch/extra_apps/DjangoUeditor/urls.py# coding:utf-8
from django import VERSIONif VERSION[0:2] > (1, 3):
    from django.conf.urls import patterns, url
else:
    from django.conf.urls.defaults import patterns, urlfrom .views import get_ueditor_controller
urlpatterns = [
    url(r'^controller/$', get_ueditor_controller)
]改为：
# coding:utf-8
from django import VERSIONif VERSION[0:2] > (1, 3):
    from django.conf.urls import url
else:
    from django.conf.urls.defaults import  urlfrom .views import get_ueditor_controller
urlpatterns = [
    url(r'^controller/$', get_ueditor_controller)
]6.可能遇到的问题
render_to_string() got an unexpected keyword argument 'context_instance'	
context must be a dict rather than RequestContext.
就是context变为
{
 "context":context
}
systemctl disable firewalld.service
7.启动脚本
pkill -9 nginx
pkill -9 srs
pkill -9 uwsgicd /usr/local/nginx/
./sbin/nginx -c conf/touch.conf &cd /usr/local/srs/
./objs/srs -c conf/my.http.flv.live.conf > /dev/null &cd /opt/
uwsgi --ini script/touch.ini &yum install -y git
srs官方文档：https://github.com/ossrs/srs/wiki/v2_CN_SampleHttp
第一步，获取SRS。详细参考GIT获取代码
git clone https://github.com/ossrs/srs
cd srs/trunk
第二步，编译SRS。详细参考Build
./configure && make
编译好后，make install 
然后复制目录
\cp -r ./objs/ /usr/local/srs/
\cp -r ./objs/nginx/ /usr/local/srs/objs/
创建软链接
ln -sf /usr/local/srs/etc/init.d/srs /etc/init.d/srs 
chkconfig --add srs编译好后，make install 
然后复制目录
\cp -r ./objs/ /usr/local/srs/
\cp -r ./objs/nginx/ /usr/local/srs/objs/
创建软链接
ln -sf /usr/local/srs/etc/init.d/srs /etc/init.d/srs 
chkconfig --add srs
8.配置脚本自启动
1、赋予脚本可执行权限（/opt/script/run.sh是你的脚本路径）
chmod +x /opt/script/run.sh 
chmod +x /opt/run.sh 2 编辑 vim /etc/rc.d/rc.local文件，在末尾增加如下内容
/opt/script/run.sh 
/opt/run.sh 
3、在centos7中，/etc/rc.d/rc.local的权限被降低了，所以需要执行如下命令赋予其可执行权限
chmod +x /etc/rc.d/rc.local9.安装redis
yum install redis
service redis start 或 systemctl start redis.service
chkconfig redis onreboot重启，观看效果。
