2、下载镜像
[root@CentOS ~]# docker pull docker.io/centos
3、查看已下载的镜像
[root@CentOS ~]# docker image lsREPOSITORY TAG IMAGE ID CREATED SIZEdocker.io/centos latest 1e1148e4cc2c 2 weeks ago 202 MBdocker.io/nginx latest 568c4670fa80 3 weeks ago 109 MBdocker.io/mongo latest 525bd2016729 5 weeks ago 383 MBdocker.io/tomcat latest 78b258e36eed 5 weeks ago 463 MBdocker.io/python latest 1e80caffd59e 5 weeks ago 923 MBdocker.io/redis latest c188f257942c 5 weeks ago 94.9 MBdocker.io/mysql latest f991c20cb508 5 weeks ago 486 MBdocker.io/httpd latest 2a51bb06dc8b 5 weeks ago 132 MBdocker.io/jenkins latest cd14cecfdb3a 5 months ago 696 MB
[root@CentOS ~]# docker imagesREPOSITORY TAG IMAGE ID CREATED SIZEdocker.io/centos latest 1e1148e4cc2c 2 weeks ago 202 MBdocker.io/nginx latest 568c4670fa80 3 weeks ago 109 MBdocker.io/mongo latest 525bd2016729 5 weeks ago 383 MBdocker.io/tomcat latest 78b258e36eed 5 weeks ago 463 MBdocker.io/python latest 1e80caffd59e 5 weeks ago 923 MBdocker.io/redis latest c188f257942c 5 weeks ago 94.9 MBdocker.io/mysql latest f991c20cb508 5 weeks ago 486 MBdocker.io/httpd latest 2a51bb06dc8b 5 weeks ago 132 MBdocker.io/jenkins latest cd14cecfdb3a 5 months ago 696 MB
4、启动镜像
[root@CentOS ~]# docker run -itd centos /bin/bashWARNING: 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 -aCONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES37c8eec506e8 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 psCONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES050e1835cbc8 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 -aCONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMESd916e60cd091 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" nginx configuration prefix: "/usr/local/nginx/conf" nginx configuration file: "/usr/local/nginx/conf/nginx.conf" nginx pid file: "/usr/local/nginx/logs/nginx.pid" nginx error log file: "/usr/local/nginx/logs/error.log" nginx http access log file: "/usr/local/nginx/logs/access.log" nginx http client request body temporary files: "client_body_temp" nginx http proxy temporary files: "proxy_temp" nginx http fastcgi temporary files: "fastcgi_temp" nginx http uwsgi temporary files: "uwsgi_temp" nginx http scgi temporary files: "scgi_temp"[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uwsgipkill -f uwsgi -9 # 关闭uwsgiuwsgi --reload uwsgi.pid #重新加载配置

~
~nginx.conf文件
worker_processes 1;events { worker_connections 1024;}http { include mime.types; default_type application/octet-stream; sendfile on; keepalive_timeout 65; server { listen 8080; server_name localhost 192.168.100.100; charset utf-8; location / { include /usr/local/nginx/conf/uwsgi_params; uwsgi_pass 127.0.0.1:8000; uwsgi_param UWSGI_SCRIPT ChinaDaas.wsgi; uwsgi_param UWSGI_CHDIR /home/ChinaDaas; } location /templates/ { alias /home/ChinaDaas/templates/; } }}
