//####centos 改变文件属性

      chmod 777 文件名

    其中：rwx也可以用数字来代替

　　r ------------4

　　w -----------2

　　x ------------1

　　- ------------0

　　行动：

　　 表示添加权限

　　- 表示删除权限

　　= 表示使之成为唯一的权限

　　当大家都明白了上面的东西之后，那么我们常见的以下的一些权限就很容易都明白了：

　　-rw------- (600) 只有所有者才有读和写的权限

　　-rw-r--r-- (644) 只有所有者才有读和写的权限，组群和其他人只有读的权限

　　-rwx------ (700) 只有所有者才有读，写，执行的权限

　　-rwxr-xr-x (755) 只有所有者才有读，写，执行的权限，组群和其他人只有读和执行的权限

　　-rwx--x--x (711) 只有所有者才有读，写，执行的权限，组群和其他人只有执行的权限

　　-rw-rw-rw- (666) 每个人都有读写的权限

　　-rwxrwxrwx (777) 每个人都有读写和执行的权限

//####登录Linux实例

×

浏览器 WebShell 方式登录

立即登录

支持复制粘贴、中文输入法，需要开启 SSH 端口（TCP:22）

标准登录方式

使用 Windows 系统的电脑

1、下载安装 Windows SSH 和 Telnet 客户端工具 Putty。 下载Putty

2、用户名： root，Host： xxx.xxx.xxx.xxx

3、按照 Putty 使用帮助进行登录。 Putty 密码方式使用帮助

使用 Linux/Mac OS X 系统的电脑（使用密码登录）

1、打开 SSH 客户端（Mac可使用系统自带的终端）

2、输入 ssh -q -l root -p 22 xxx.xxx.xxx.xxx

3、输入 CVM 实例密码进行登录。

使用 Linux/Mac OS X 系统的电脑（使用密钥登录）

1、打开 SSH 客户端（Mac可使用系统自带的终端）。

2、查找您实例关联的 SSH 密钥文件本地存放地址。

3、您的密钥必须不公开可见，SSH 才能工作。请使用此命令： chmod 400 [密钥文件路径]。

4、输入命令： ssh [-i 密钥文件路径] [email protected]。

浏览器 VNC 方式登录 不推荐

暂不支持复制粘贴、中文输入法。 立即登录

提示：采用VNC方式登录，请务必开启 MFA 二次验证提高安全保障级别
