pixel slate 工程机装最新chromeos系统 记录一下...虽然以后可能也不会用到了首先pixel slate 工程机自带的系统不能联网升级，令人讨厌，并且系统和正式版也不同，有丑陋的版本号升级步骤如下：1.进入开发者模式此操作会清除所有数据！对于pixel slate，同时按下音量上下键，再按住电源键10s，然后松开电源，就会进入恢复界面。此时松开并再次按下音量上下键，会问是否要关闭操作系统检验，按照提示关闭，就进入了开发者模式。2.允许usb启动激活并进入系统，按ctrl+Alt+t，打开终端，输入shell，进入shell命令行，输入sudo crossystem dev_boot_usb=1 sudo crossystem dev_boot_legacy=1 #开启biossudo密码应该是test0000然后就可以usb启动3.刻录恢复镜像到u盘有两种办法。（1）用Google的官方恢复工具叫Chromebook Recovery Utility，一个chrome浏览器的app。先安装，然后按照提示一步步来，就获得了恢复u盘（2）直接下载恢复镜像刻录。各个chromebook的恢复镜像在附件里。先下载解压，得到chromexxxx.bin，然后用任意linux系统写入镜像dd if=chromexxxx.bin of=/dev/sda iflag=fullblock oflag=sync status=progress bs=4M将sda换成你的u盘，写入完成即可4.恢复系统根据Google官方的说法，是如1.所讲的进入恢复界面插入U盘，但是实测他会说你的U盘检测不到有chromeos系统于是我们在开机时从U盘启动，然后就会自动开始恢复系统。等待8分钟左右就会提示恢复完成5.升级系统恢复完成后，开机，再次激活，你会发现分辨率变的很奇怪，不管他先进系统，开始更新，等待更新完后分辨率就正常了。然后调节触摸板为澳大利亚模式。

jupyterhub docker 安装 这个jupyterhub自带了notebook和jupyterlab先创建一个ubuntu18.04容器docker run -d --hostname jupyterlab-server --name jupyterhub -p 83:8000 -i -t ubuntu:18.04 /bin/bash #然后进入容器 docker exec -it jupyterhub /bin/bash #按照正常方法安装anaconda wget https://mirrors.tuna.tsinghua.edu.cn/anaconda/archive/Anaconda3-2019.10-Linux-x86_64.sh bash Anaconda3-2019.10-Linux-x86_64.sh conda install -c conda-forge jupyterhub然后进行配置注意c.JupyterHub.ip = 'your-ip'不要填127.0.0.1（不然访问不了）其余随便然后chmod -R 777 /home(很重要不然会500)就可以了说一下踩过的坑：c.JupyterHub.ip = ''要是设成127.0.0.1，反代之后就无法访问（refused）以/home目录存放文件时，没有chmod -R 777 /home 则报500 错误c.Spawner.ip = '*'则报5034.上述一切做好后，会发现连不上内核？？因为反代没设置好。需要在nginx主配置http里加 map $http_upgrade $connection_upgrade { default upgrade; '' close; }反代配置为：#PROXY-START/ location / { proxy_pass http://127.0.0.1:83; proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; add_header X-Cache $upstream_cache_status; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection $connection_upgrade; #Set Nginx Cache add_header Cache-Control no-cache; expires 12h; } #PROXY-END/配置文件：jupyterhubconfig.zip

gitlab docker 安装和汉化 首先先查找最新汉化包https://gitlab.com/xhang/gitlab/现在是12.3.5所以下载运行相应docker：sudo docker run --detach \ --hostname gitlab-server \ --publish 443:82 --publish 80:84 --publish 22:8022 \ --name gitlab \ --restart always \ --volume /srv/gitlab/config:/etc/gitlab \ --volume /srv/gitlab/logs:/var/log/gitlab \ --volume /srv/gitlab/data:/var/opt/gitlab \ gitlab/gitlab-ee:12.3.5-ee.0`(为了https)然后编辑配置文件vim /srv/gitlab/config/gitlab.rbexternal_url 'https://git.dnlab.net' gitlab_rails['gitlab_shell_ssh_port'] = 8022 nginx['redirect_http_to_https'] =true nginx['ssl_certificate'] = "/etc/gitlab/ssl/server.crt" nginx['ssl_certificate_key'] = "/etc/gitlab/ssl/server.key" gitlab_rails['smtp_enable'] = true gitlab_rails['smtp_address'] = "smtp.office365.com" gitlab_rails['smtp_port'] = 587 gitlab_rails['smtp_user_name'] = "canoziia@dnlab.net" gitlab_rails['smtp_password'] = "********" gitlab_rails['smtp_domain'] = "smtp.office365.com" gitlab_rails['smtp_authentication'] = :login #gitlab_rails['smtp_enable_starttls_auto'] = true #gitlab_rails['smtp_tls'] = true gitlab_rails['gitlab_email_from'] = "canoziia@dnlab.net"`https自签名方法：修改配置文件xieshuang@VM_177_101_centos gitlab]$ sudo vim /etc/gitlab/gitlab.rb #13行的 http >> https external_url 'https://ip:port' #修改nginx配置 810行 nginx['redirect_http_to_https'] =true nginx['ssl_certificate'] = "/etc/gitlab/ssl/server.crt" nginx['ssl_certificate_key'] = "/etc/gitlab/ssl/server.key"生成秘钥与证书#秘钥脚本，将以下内容保存为shell脚本，然后运行 #出现提示输入信息的地方输入信息，先输入域名然后4次证书密码，任意密码，四次保持一致。 #!/bin/sh`` #create self-signed server certificate: read -p "Enter your domain [139.199.125.93]: " DOMAIN echo "Create server key..." openssl genrsa -des3 -out $DOMAIN.key 1024 echo "Create server certificate signing request..."
