1,开机初始化的配置
iptables -F 清空防火墙
/etc/init.d/iptables stop  #关闭iptables
setenforce 0  #暂停selinux

#编译安装python3

环境准备
yum install gcc patch libffi-devel python-devel  zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel -y

#下载python3的源码包
wget https://www.python.org/ftp/python/3.4.7/Python-3.4.7.tar.xz
#解压缩源码包
xz -d Python-3.4.7.tar.xz
tar -xf Python-3.4.7.tar 
#切换python3目录 
cd Python
-3.4.7
#释放脚本文件
.
/configure --prefix=/opt/python347
#编译,编译安装
make
&& make install
#建立软连接
ln
-s /opt/python347/bin/python3 /usr/local/bin/python3
#将编译的python3的环境变量添加到pATH
vim
/etc/profile
#写入到配置文件,永久生效 在最底行写入
export PATH
=$PATH:/opt/python347/bin/ 然后 source /etc/profile
使得配置文件生效
#python解释器的自动补全功能 yum install
-y readline-devel -y pip install readline import readline,rlcompleter readline.parse_and_bind('tab:complete')
#python虚拟环境 virtualenv
--no-site-packages venv
#创建venv虚拟环境 #激活虚拟环境 source venv
/bin/activate
#虚拟环境主要是对环境变量进行更改 echo $PATH
#退出虚拟环境 deactivate #ipython pip3 install ipython
#交互式的解释器 #notebook pip3 install notebook

 

 

安装python

1,开机初始化的配置

/etc/init.d/iptables stop  #关闭iptables
setenforce 0  #暂停selinux

#编译安装python3

环境准备
yum install gcc patch libffi-devel python-devel  zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel -y

#下载python3的源码包

#编译,编译安装
 make && make install 
 #建立软连接
 ln -s /opt/python347/bin/python3 /usr/local/bin/python3

下载 readline
 yum install -y readline -devel


查看环境变量:

[root@tencentcloud ~]# echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin




 

 

 虚拟环境的安装

#python虚拟环境
virtualenv --no-site-packages venv #创建venv虚拟环境
#激活虚拟环境
source venv/bin/activate
#虚拟环境主要是对环境变量进行更改
echo $PATH
#退出虚拟环境
deactivate

 

 

1. 下载NGINX 

wget http://nginx.org/download/nginx-1.14.0.tar.gz

2.解压

tar xf nginx-1.14.0.tar.gz 

3. 编译安装三部曲 

 

进入 nginx 目录下 ,注意目录里有个configure 文件
./configure --prefix=/opt/nginx-1.14.0

make && make install

 

4.开启服务

4.启动nginx,进入sbin目录,找到nginx启动命令
cd sbin
./nginx #启动
./nginx -s stop #关闭
./nginx -s reload #重新加载

5.查看conf文件

cat conf/nginx.conf
[root@tencentcloud nginx-1.12.2]# cat conf/nginx.conf

6.创建软连接

[root@tencentcloud nginx-1.12.2]# ln -s  /sbin/nginx  /sbin/

 

 

 

5.关闭防护墙

chkconfig iptables off  

永久关闭。
chkconfig|grep ipt
vim /etc/selinux/config

 

 6. 去掉文件里的# 和空行 

egrep -v "^$|#" nginx.conf.default


egrep -v "^$|#" nginx.conf.default >nginx.conf

  

 

4. 测试 

curl 10.10.0.1

    saltstack(python编写的自动化工具)
    原本公司的组织架构是;  
        apahce+oralce数据库+redis+saltstack+java+perl(收费)
        走向一个开源,免费的技术架构(省钱)
        nginx + mysql + redis +stal +java +python(glances一个开源的服务器监控工具)
        
    ansible + 一号车面试的时候,ansible+python+django 开发的cmdb平台
    saltstack + python +django  运维平台
    
#salt环境准备,需要再两台机器一起执行
准备好2台服务器
master 192.168.12.44
slave  192.168.12.45
#设置好本地/etc/hosts解析
vim /etc/hosts#写入以下解析记录
192.168.12.44 master
192.168.12.45 slave
#关闭服务器安全策略
/etc/init.d/iptables stop
iptables -F
#关闭服务器selinux
getenforce #检测selinux是否开启
setenforce 0 #临时关闭selinux
#使用sed永久关闭selinux(此步骤需要重启linux)

#清空yum源缓存,然后更新新的yum缓存(非必须的操作)

#uWSGI 安装配置

#提前安装好python3环境
https://www.cnblogs.com/pyyu/p/7402145.html
#virtualenv
#请确保你的虚拟环境正常工作
https://www.cnblogs.com/pyyu/p/9015317.html
#安装django1.11
pip3 install django==1.11
#创建django项目mysite
django-admin startproject mysite
#创建app01
python3 manage.py startapp app01

#mysite/settings.py
#settings.py设置
ALLOWED_HOSTS = ['*']
install app01

#mysite/urls.py
from app01 import views
urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^hello_django/', views.hello),
]

#app01/views.py
from django.shortcuts import render,HttpResponse

# Create your views here.
def hello(request):
    print('request is :',request)
    return HttpResponse('django is ok ')

#pip3安装uwsgi
#进入虚拟环境venv,安装uwsgi
(venv) [root@slave 192.168.11.64 /opt]$pip3 install uwsgi
#检查uwsgi版本
(venv) [root@slave 192.168.11.64 /opt]$uwsgi --version
2.0.17.1
#检查uwsgi python版本
uwsgi --python-version
############################################
#启动一个python web服务
uwsgi --http :8000 --wsgi-file test.py
http :8000: 使用http协议,端口8000
wsgi-file test.py: 加载指定的文件,test.py
#test.py
def application(env, start_response):
    start_response('200 OK', [('Content-Type','text/html')])
    return [b"Hello World"] # python3

#uWsgi热加载python程序

#在启动命令后面加上参数
uwsgi --http :8088 --module mysite.wsgi --py-autoreload=1 
#此时修改django代码,uWSGI会自动加载django程序,页面生效
运行django程序

#mysite/wsgi.py  确保找到这个文件
uwsgi --http :8000 --module mysite.wsgi
module mysite.wsgi: 加载指定的wsgi模块

        
    
    
#二、nginx+uWSGI+django+virtualenv+supervisor(进程管理工具)发布我们的django项目


1.配置nginx,通过反向代理结合uWSGI

       location / {
            root   html;
            include /opt/nginx112/conf/uwsgi_params;
            uwsgi_pass 0.0.0.0:8000;
            index  index.html index.htm;
        }

2.安装好supervisor
#在python2环境下安装
yum install python-setuptools
easy_install supervisor
#通过命令生成supervisor的配支文件
echo_supervisord_conf > /etc/supervisord.conf
#然后再/etc/supervisord.conf末尾添加上如下代码!!!!!!
[program:s10_django]
command= /home/venv1/bin/uwsgi --uwsgi 0.0.0.0:8000 --chdir /home/mysite --home=/home/venv1 --module mysite.wsgi
directory=/home/mysite
startsecs=0
stopwaitsecs=0
autostart=true
autorestart=true

3.启动好nginx
/opt/nginx112/sbin/nginx

4.启动supervisor 
supervisord -c /etc/supervisord.conf
    -管理supervisor的命令
    supervisorctl start s10_django 
    supervisorctl stop  s10_django 
    supervisorctl restart s10_django
    
5.此时访问192.168.12.44 访问nginx的80端口,已经反向代理找到后端的django应用



####补充:
PS1命令提示符的更改
export PS1='[\u@\h \w \t]\$'
#使得永久生效
vim /etc/profile
#写入
export PS1='[\u@\h \w \t]\$'



    
    
#三、docker容器基本使用

大家可能接触到的服务器环境(代码运行的环境)

物理机+centos 

vmware esxi  + centos 

阿里云/腾讯云/亚马逊云

docker容器   (项目跑在容器中)

    


#环境准备
#查看linux发行版
cat /etc/redhat-release 
#内核版本查看
uname -r 
#安装docker,配置yum的epel源
yum install docker 

#启停docker 
systemctl status docker  #检查docker状态
systemctl start  docker #启动docker
systemctl stop    docker  #关闭docker


#配置docker镜像源加速
curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://95822026.m.daocloud.io
#查看镜像源加速
[root@oldboy_python ~ 14:33:39]#cat /etc/docker/daemon.json
{
    "registry-mirrors": ["http://95822026.m.daocloud.io"],
    "insecure-registries": []
}

#下载hello-world镜像
docker pull hello-world
#查看docker镜像
docker images 
#运行docker hello-world镜像
docker run 镜像名/镜像id/镜像id的前3位
#搜索docker镜像(image)
docker search centos 
docker search django(#搜索django镜像)
#运行一个交互式的centos容器
docker run -it centos /bin/bash 
#在后台运行一个容器,执行shell,每秒打印一个hellodocker,(此命令会返回一个容器id)
docker run -d centos /bin/sh -c "while true;do echo hello centos; sleep 1;done"
#查看容器进程
docker ps #用于查看正在运行的容器
docker ps -a #用于查看所有运行过的容器
#查看容器运行的日志
docker logs 容器id
#删除容器
    -先停止正在运行的容器
    docker stop 容器id
    docker rm 容器id
    -强制删除正在运行的容器
    docker rm -f 容器id
#删除已有的docker镜像(image)
docker rmi 镜像id

#https://www.cnblogs.com/pyyu/p/9485268.html  docker部署博客


###########重要性
1.uwsgi发布django程序
2.docker容器的使用
3.mysql主从复制
4.把笔记所有linux命令敲一遍
