macos移除下载镜像quarantine属性 一、什么是Quarantine属性？　　Quarantine属性通常用于描述计算机系统或网络安全领域中的安全特性，其指的是对于具有潜在威胁的文件、程序或数据进行隔离和限制访问的一种机制。当一个文件或程序被识别为可能包含恶意代码、病毒、蠕虫等安全威胁时，系统可以将其放置在隔离区域中，以防止其进一步感染系统或网络。这个隔离区域就被称为"quarantine"，隔离期间，该文件或程序不允许执行或访问系统资源，直到被确定为安全或永久删除。Quarantine属性可以在许多安全软件或操作系统中找到，例如防病毒软件、防火墙、操作系统的安全设置等。通过使用Quarantine属性，用户可以更好地保护他们的计算机和网络不受安全威胁的侵害。　　苹果系统有一个GateKeeper保护机制（自 OSX 10.5 加入）。从互联网上下载来的文件，会被自动打上com.apple.quarantine标志，翻译过来就是免疫隔离，系统根据这个附加属性对这个文件作出限制。在安装软件的时候需要移除quarantine属性，二、解除Quarantine属性打开实用工具里的【终端】并输入下面的命令：sudo xattr -r -d com.apple.quarantine然后把下载的镜像文件拖拽到终端里就会出现文件路径如下admin@supermac ~ % sudo xattr -r -d com.apple.quarantine /Users/admin/Downloads/Adobe_Photoshop_2021_22.4.2.242_ACR13.3_SP_20210617.dmg回车即可解除该属性

gitlab忘记密码 一、背景由于公司在公司内部服务新装一台Gitlab服务器，长期未登录导致密码忘记。二、邮箱方式找回1.在gitlab登录窗口如果密码忘记了登录不进入，可以先尝试点击登录框下方的Forgot your password来通过邮箱的方式找回，如果邮箱不可以使用了，则看下面的强制找回方法.2.输入邮箱账号找回输入当初设置的邮箱帐号，这一步前提是邮箱可以正常使用的情况下才可以使用的方法3.重设密码输入正确的邮箱后，点击邮箱会受到一封重设密码邮件，点击Reset password进入浏览器重新输入新密码确定重新登录即可。三、Bash命令方式找回1.切换到git用户[root@staging ~]# su git2.查看gitlab命令文件sh-4.2$ ls alertmanager gitaly gitlab-exporter gitlab-workhorse nginx postgresql redis backups git-data gitlab-rails grafana node-exporter prometheus trusted-certs-directory-hash bootstrapped gitlab-ci gitlab-shell logrotate postgres-exporter public_attributes.json3.进入gitlab控制台sh-4.2$ gitlab-rails console -------------------------------------------------------------------------------- GitLab: 13.0.3 (e2397fc2acb) FOSS GitLab Shell: 13.2.0 PostgreSQL: 11.7 -------------------------------------------------------------------------------- Loading production environment (Rails 6.0.3)4.查询gitlab超级管理员信息irb(main):001:0> user = User.where(id:1).first => #<User id:1 @root>5.重置密码并报存用户对象irb(main):004:0> user.password='*******' irb(main):005:0> user.save!

docker版nexus迁移服务器 一、备份nexus数据备份nexus的持久化目录数据使用压缩命令 tar -czvf nexus/data/nexus-data 得到压缩文件nexus.tar.gz,将其拷贝到新服务器待用二、运行新nexus运行与旧服务器相同版本的nexus注意需要先创建好需要用的持久化目录并赋权，例如 mkdir -p nexus/data/nexus-data && sudo chown -R 200:200 nexus验证服务可用性curl -u admin:admin123 http://localhost:8081/service/metrics/ping 如果不通会报错三、替换旧数据解压备份数据包tar -xzvf nexus.tar.gz ，不要与新运行的nexus服务持久化目录同目录，或重命名为nexus_backup，并赋权， sudo chown -R 200:200 nexus_backup拷贝覆盖新nexus服务的数据sudo cp -r nexus_backup/data nexus/四、重启服务docker restart nexus无法正常重启，报错无权限重新赋权持久化目录
