4、启动镜像
[root@CentOS ~]# docker run -itd centos /bin/bash
WARNING: IPv4 forwarding is disabled. Networking will not work.
37c8eec506e8cb6867c2352dee59fc47649e903a469ab07bc561c8e3407dcd0a
问题：创建容器的时候报错WARNING: IPv4 forwarding is disabled. Networking will not work.
解决办法：
打开文件：[root@CentOS ~]# vi /usr/lib/sysctl.d/00-system.conf
添加如下代码：net.ipv4.ip_forward=1
重启network服务：[root@CentOS ~]# systemctl restart network
完成以后，删除错误的容器，再次创建新容器
删除容器
查看所有运行或者不运行容器
[root@CentOS ~]# docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
37c8eec506e8 centos "/bin/bash" 7 minutes ago Up 7 minutes laughing_engelbart
停止运行容器
[root@CentOS ~]# docker stop 37c8eec506e8
删除容器
[root@CentOS ~]# docker rm 37c8eec506e8
重新创建容器
[root@CentOS ~]# docker run -itd -p 80:9000 --name centos docker.io/centos /bin/bash
5、查看容器
[root@CentOS ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
050e1835cbc8 docker.io/centos "/bin/bash" 51 seconds ago Up 50 seconds 0.0.0.0:80->9000/tcp centos
6、进入容器
[root@CentOS ~]# docker exec -it 050e1835cbc8 /bin/bash
[root@CentOS ~]# docker attach 050e1835cbc8
[root@050e1835cbc8 /]#
7、通过配置文件修改docker容器端口映射
[root@CentOS ~]# docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
d916e60cd091 docker.io/centos "/bin/bash" 2 days ago Up 6 minutes 0.0.0.0:80->80/tcp centos
[root@CentOS ~]# docker inspect d916e60cd091|grep Id
"Id": "d916e60cd09151085a9dc08377cb3e152b5dc86197b8591bbf5b0a129c840760",
[root@CentOS ~]# docker stop centos
[root@CentOS ~]# cd /var/lib/docker/containers/
停止 docker 引擎服务，systemctl stop docker 或者 service docker stop
进入对应 Id 所在目录后，修改 /var/lib/docker/containers/{ 容器 ID+ 一些字符串}/hostconfig.json 中
"PortBindings":{"容器端口 /tcp":[{"HostIp":"","HostPort":"宿主机端口"}]
例如：
"PortBindings":{"80/tcp":[{"HostIp":"","HostPort":"80"}],"8080/tcp":[{"HostIp":"","HostPort":"8080"}],"8888/tcp":[{"HostIp":"","HostPort":"8888"}]}
同时修改同目录下的 config.v2.json 中
"ExposedPorts":{"容器端口 /tcp":{}}
"Ports":{"容器端口 /tcp":[{"HostIp":"0.0.0.0","HostPort":"宿主机端口"}]}
例如：
"ExposedPorts":{"80/tcp":{},"8080/tcp":{},"8888/tcp":{}}
"Ports":{"80/tcp":[{"HostIp":"0.0.0.0","HostPort":"80"}],"8080/tcp":[{"HostIp":"0.0.0.0","HostPort":"8080"}],"8888/tcp":[{"HostIp":"0.0.0.0","HostPort":"8888"}]}
重启服务, 启动容器 (systemctl start docker/service docker start)
8、查看docker容器IP
想看到docker容器的ip先安装net-tools
[root@050e1835cbc8 ~]# yum install net-tools -y
之后就可以用ifconfig查看
[root@050e1835cbc8 ~]# ifconfig
二、CentOS环境安装Python3.7
1、安装编译相关工具
[root@050e1835cbc8 /]# yum -y groupinstall "Development tools"
[root@050e1835cbc8 /]# yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel
[root@050e1835cbc8 /]# yum install libffi-devel -y
2、下载安装包解压
[root@050e1835cbc8 ~]# yum -y install wget
[root@050e1835cbc8 ~]# wget https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tar.xz
[root@050e1835cbc8 ~]# tar -xvJf Python-3.7.0.tar.xz
3、编译安装
[root@050e1835cbc8 ~]# mkdir /usr/local/python3 #创建编译安装目录
[root@050e1835cbc8 ~]# cd Python-3.7.0
[root@050e1835cbc8 Python-3.7.0]# ./configure --prefix=/usr/local/python3
[root@050e1835cbc8 Python-3.7.0]# make && make install
4、创建软连接
[root@050e1835cbc8 ~]# ln -s /usr/local/python3/bin/python3 /usr/local/bin/python3
[root@050e1835cbc8 ~]# ln -s /usr/local/python3/bin/pip3 /usr/local/bin/pip3
5、验证是否成功
[root@050e1835cbc8 ~]# python3 -V
[root@050e1835cbc8 ~]# pip3 -V
三、CentOS环境安装Nginx
1、gcc 安装
安装 nginx 需要先将官网下载的源码进行编译，编译依赖 gcc 环境。nginx也需要 gcc 环境。
[root@050e1835cbc8 ~]# yum install gcc-c++
2、pcre pcre-devel 安装
PCRE(Perl Compatible Regular Expressions) 是一个Perl库，包括 perl 兼容的正则表达式库。nginx 的 http 模块使用 pcre 来解析正则表达式，所以需要在 linux 上安装 pcre 库，pcre-devel 是使用 pcre 开发的一个二次开发库。nginx也需要此库。
[root@050e1835cbc8 ~]# yum install -y pcre pcre-devel
3、zlib 安装
zlib 库提供了很多种压缩和解压缩的方式， nginx 使用 zlib 对 http 包的内容进行 gzip ，所以需要在 Centos 上安装 zlib 库。
[root@050e1835cbc8 ~]# yum install -y zlib zlib-devel
4、openssl openssl-devel安装
OpenSSL 是一个强大的安全套接字层密码库，囊括主要的密码算法、常用的密钥和证书封装管理功能及 SSL 协议，并提供丰富的应用程序供测试或其它目的使用。nginx 不仅支持 http 协议，还支持 https（即在ssl协议上传输http），所以需要在 Centos 安装 OpenSSL 库。
[root@050e1835cbc8 ~]# yum install -y openssl openssl-devel
5、下载安装包解压
[root@050e1835cbc8 ~]# wget https://nginx.org/download/nginx-1.14.2.tar.gz
[root@050e1835cbc8 ~]# tar -zxvf nginx-1.14.2.tar.gz
6、编译安装
[root@050e1835cbc8 ~]# cd nginx-1.14.2
[root@050e1835cbc8 nginx-1.14.2]# ./configure
*
*
Configuration summary
+ using system PCRE library
+ OpenSSL library is not used
+ using system zlib library
nginx path prefix: "/usr/local/nginx"
nginx binary file: "/usr/local/nginx/sbin/nginx"
nginx modules path: "/usr/local/nginx/modules"

[root@050e1835cbc8 nginx-1.14.2]# make
[root@050e1835cbc8 nginx-1.14.2]# make install
7、查找安装路径
[root@050e1835cbc8 nginx-1.14.2]# whereis nginx
8、启动、停止nginx
[root@050e1835cbc8 nginx-1.14.2]# cd /usr/local/nginx/sbin/
[root@050e1835cbc8 sbin]# ./nginx
[root@050e1835cbc8 sbin]# ./nginx -s stop
[root@050e1835cbc8 sbin]# ./nginx -s quit
[root@050e1835cbc8 sbin]# ./nginx -s reload
9、查看nginx是否启动成功
[root@050e1835cbc8 sbin]# curl localhost
[root@050e1835cbc8 sbin]# ps -aux|grep nginx
10、修改nginx配置
[root@050e1835cbc8 sbin]# vi /usr/local/nginx/conf/nginx.conf
*
server {
listen 80;#修改端口9000
server_name localhost;
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
root html;
index index.html index.htm;
}
*
systemctl stop firewalld.service #停止firewall
systemctl disable firewalld.service #禁止firewall开机启动
firewall-cmd –state #查看默认防火墙状态（关闭后显示notrunning，开启后显示running）
四、CentOS环境通过Python3安装django和uwsgi以及配置
[root@050e1835cbc8 ~]# pip3 install django
*
*
You are using pip version 10.0.1, however version 18.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
安装提示时需要更新pip
[root@050e1835cbc8 ~]# python3 -m pip install --upgrade pip
[root@050e1835cbc8 ~]# pip3 install uwsgi
创建软链接可以在终端使用uwsgi命令
[root@050e1835cbc8 ~]# ln -s /usr/local/python3/bin/uwsgi /usr/bin/uwsgi
进入/home/文件路径
[root@050e1835cbc8 home]# pwd
/home/
创建django项目
[root@CentOS www]# python3 /usr/local/python3/bin/django-admin.py startproject ChinaDaas
进入项目路径
[root@CentOS www]# cd ChinaDaas/
启动项目测试django
[root@CentOS ChinaDaas]# python3 manage.py runserver
修改settings.py文件ALLOWED_HOSTS = ['*']
uwsgi --ini uwsgi.ini # 启动uwsgi配置
ps -ef |grep uwsgi
uwsgi --stop uwsgi.pid # 关闭uwsgi
pkill -f uwsgi -9 # 关闭uwsgi
uwsgi --reload uwsgi.pid #重新加载配置
uwsgi.ini文件
[uwsgi]
#请求方式与端口号
socket = :8080
#日志文件
daemonize = /usr/local/nginx/uwsgi_temp/uwsgi.log
pidfile = /usr/local/nginx/uwsgi_temp/uwsgi.pid
#允许主进程存在
master = true
#开启进程数
processes = 4
#开启线程数
threads =2
#当服务器退出时自动清理环境
vacuum = true
