#### QEMU
[Qemu](https://gitee.com/maygeek/qemu)

#### iptable 端口映射
[iptables实现端口映射](https://blog.csdn.net/xin_yu_xin/article/details/46416101)
#### Docker 常用操作
*  [VNC访问ubuntu容器](https://blog.csdn.net/spylyt/article/details/79944772)
*   systemctl daemon-reload
*   退出 ctrl+P+Q
*   普通用户运行,  需要断开ssh重新连接
```
sudo groupadd docker
sudo usermod -aG docker ${USER}
sudo systemctl restart docker
```
*  安装
```
wget -qO- https://get.docker.com |sh 
curl -sSL https://get.daocloud.io/docker | sh
curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://2a22c3ad.m.daocloud.io
/etc/docker/daemon.json
{
"registry-mirrors": ["https://***.mirror.aliyuncs.com"]
}
```
*   代理
/etc/systemd/system/docker.service.d/http-proxy.conf
```
[Service]
Environment="HTTP_PROXY=http://defra1c-proxy.emea.xxx-net.net:8080/"
Environment="HTTPS_PROXY=http://defra1c-proxy.emea.xxx-net.net:8080/"
Environment="NO_PROXY=docker-registry.xxx.net,localhost,127.0.0.0/8,10.0.0.0/8,172.16.0.0/12,192.168.0.0/16,*.local,xxx.net"
```
*  镜像
[国内镜像](https://www.cnblogs.com/wushuaishuai/p/9984228.html)

*   docker file
```
FROM centos:7
COPY yum.conf  /etc/yum.conf
RUN yum update
```
* 导出导入
```
docker save eb40dcf64078 > img.tar
docker load < img.tar  
docker load -i sct.img.xz 
docker tag  d1ffb1ac7a9f linsee
docker save  your_iamges:1.0 |  docker -H your_ip:port load //远程迁移 端口是多少？
```
*   [不使用 ADD/COPY 添加临时文件](https://www.jb51.cc/docker/436458.html)
    
    例如rpm安装完就不需要, add会让镜像变得庞大
```
python -m http.server --bind 192.168.178.20 8000

curl file://localhost/home/user/program.zip -o /tmp/

```

*   常见问题： 
1. docker: Error response from daemon: toomanyrequests: 
添加 /etc/docker/daemon.json
```
{ "registry-mirrors": ["https://registry.docker-cn.com"] }
```
2. 网络无法访问
```
vi /etc/default/docker
DOCKER_OPTS="--dns xxx.xxx.xxx.xxx"
```

3.  挂载目录
```
docker run -v /home/b2zhang/docker:/home/docker:rw -itd centos:7
docker build -t tag -f my.df .
```
4. 用户
```
    uid=$(id -u)
    gid=$(id -g)

    docker run -it --rm ${ADDITIONAL_ARGS} \
        -e SVN_USER="${SVN_USER}" -e SVN_PASSWORD="${SVN_PASSWORD}" \
        --env http_proxy="${http_proxy}" \
        --env https_proxy="${https_proxy}" \
        --env no_proxy="${no_proxy}" \
        ${MOUNTS} \
        ${DOCKER_IMAGE} \
        /bin/bash -c "groupadd -g ${gid} ${USER} && useradd -M -u ${uid} -g ${gid} -s /bin/bash --home-dir ${HOME} ${USER} && \
            chown ${uid}:${gid} ${HOME} && \
            ${ADDITIONAL_SETUP} && \
            echo \"${DOCKER_YOCTO_BUILD_SETUP}\" >> \"${HOME}/setup.sh\" && \
            chmod +x ${HOME}/setup.sh && \
            su ${USER}"

```

[git]
name=Wandisco GIT Repository
baseurl=http://opensource.wandisco.com/centos/7/git/$basearch/
enabled=1
gpgcheck=0
#proxy=_none_
```

#### TIPS


1.  注销用户
```
pkill -kill -t tty1
```


#### NGINX

将/etc/selinux/config文件修改为disabled
```
SELINUX-disabled

/usr/sbin/sestatus -v 
getenforce
setenforce 0
```
vi /etc/nginx/nginx.conf
```

        #root         /var/www/html; #根目录修改这里
        root         /usr/share/nginx/html;

        # Load configuration files for the default server block.
        include /etc/nginx/default.d/*.conf;

        location / {
                autoindex on; # 不加这个 打开目录会显示403
        }


```
#### Python
1. 代理
```
pip install pandas --proxy=http://10.20.217.2:8080
~/.config/pip/pip.conf
[global]
proxy=http://xxx.xxx.xxx.xxx:8080 
```

#### 虚拟机

[解决共享目录 can not create link](https://www.jianshu.com/p/9ef5ef856d54)
```
cd C:\Program Files\Oracle\VirtualBox
./VBoxManage setextradata deepin VBoxInternal2/SharedFoldersEnableSymlinksCreate/sabdbox 1
VBoxManage getextradata deepin enumerate

 secpol.msc   本地安全策略-->本地策略-->用户权限分配-->创建符号链接-->添加用户或者组权限
```

```
sudo mount -t vboxsf sandbox /sandbox
sudo vi etc/fstab
sandbox /sandbox  vboxsf auto,rw,comment=systemd.automount 0 0
mount -a
```
