-How To Set Readonly File Permissions On Linux / Unix Web Server DocumentRoot
-======
-
-How do I set a read-only permission for all of my files stored in /var/www/html/ directory?
-
-You can use the chmod command to set read-only permission for all files on a Linux / Unix / macOS / Apple OS X / *BSD operating systems. This page explains how to setup read only file permission on Linux or Unix web server such as Nginx, Lighttpd, Apache and more.
-
-[![Proper read-only permissions for Linux/Unix Nginx/Apache web server's directory][1]][1]
-
-### How to set files in read-only mode
-
-
-The syntax is:
-```
-### use only for files ##
-chmod 0444 /var/www/html/*
-chmod 0444 /var/www/html/*.php
-```
-
-### How to to set directories in read-only mode
-
-TO set directories in read-only mode, enter:
-```
-### use only for dirs ##
-chmod 0444 /var/www/html/
-chmod 0444 /path/to/your/dir/
-# ***************************************************************************
-# Say webserver user/group is www-data, and file-owned by ftp-data user/group
-# ***************************************************************************
-# All files/dirs are read-only
-chmod -R 0444 /var/www/html/
-# All files/dir owned by ftp-data
-chown -R ftp-data:ftp-data /var/www/html/
-# All directories and sub-dirs has 0445 permission (so that webserver user www-data can read our files)
-find /var/www/html/ -type d -print0 | xargs -0 -I {} chmod 0445 "{}"
-```
-To find all files (including sub-directories in /var/www/html) and set read-only permission, enter:
-```
-### works on files only ##
-find /var/www/html -type f -iname "*" -print0 | xargs -I {} -0 chmod 0444 {}
-```
-
-However, you need to set set read-only and execute permission on /var/www/html and all sub-directories so that web server can enter into your DocumentRoot, enter:
-```
-### works on dirs only ##
-find /var/www/html -type d -iname "*" -print0 | xargs -I {} -0 chmod 0544 {}
-```
-
-### A warning about write permission
-
-Please note that write access on a directory /var/www/html/ allows anyone to remove or add new files. In other words, you may need to set a read-only permission for /var/www/html/ directory itself:
-```
-### read-only web-root but web server allowed to read files ##
-chmod 0555 /var/www/html
-```
-
-In some cases you can change file owner and group to set tight permissions as per your setup:
-```
-### Say /var/www/html is owned by normal user, you can set it to root:root or httpd:httpd (recommended) ###
-chown -R root:root /var/www/html/
- 
-### Make sure apache user owns /var/www/html/ ##
-chown -R apache:apache /var/www/html/
-```
-
-### A note about NFS exported directories
-
-You can specify whether the directory should have [read-only or read/write permissions using /etc/exports][2] file. This file defines the various shares on the NFS server and their permissions. A few examples:
-```
-# Read-only access to anyone
-/var/www/html *(ro,sync) 
- 
-# Read-write access to a client on 192.168.1.10 (upload.example.com)
-/var/www/html 192.168.1.10(rw,sync)
-```
-
-### A note about read-only Samba (CIFS) share for MS-Windows clients
-
-To share sales as read-only, update smb.conf as follows:
-```
-[sales]
-comment = Sales Data
-path = /export/cifs/sales
-read only = Yes
-guest ok = Yes
-```
-
-### A note about file systems table
-
-You can use the /etc/fstab file on Unix or Linux to configure to mount certain files in read-only mode. You need to have a dedicated partition. Do not set / or other system partitions in read-only mode. In this example /srv/html is set to read-only mode using /etc/fstab file:
-```
-/dev/sda6 /srv/html ext4 ro 1 1
-```
-
-You can use the mount command to [remount partition in read-only mode][3] (run it as the root user):
-```
-# mount -o remount,ro /dev/sda6 /srv/html
-```
-OR
-```
-# mount -o remount,ro /srv/html
-```
-The above command will try to attempt to remount an already-mounted filesystem at /srv/html. This is commonly used to change the mount flags for a filesystem, especially to make a readonly filesystem writeable. It does not change device or mount point. To make file system writable again, enter:
-```
-# mount -o remount,rw /dev/sda6 /srv/html
-```
-OR
-```
-# mount -o remount,rw /srv/html
-```
-
-### Linux: chattr Command
-
-You can change file [attributes on a Linux file system to read-only][4] using the chattr command:
-```
-chattr +i /path/to/file.php
-chattr +i /var/www/html/
- 
-# find everything in /var/www/html and set to read-only #
-find /var/www/html -iname "*" -print0 | xargs -I {} -0 chattr +i {}
-```
-
-To remove read-only attribute pass the -i option:
-```
-# chattr -i /path/to/file.php
-```
-FreeBSD, Mac OS X and other BSD unix user can use the [chflags command][5]:
-```
-### set read-only ##
-chflags schg /path/to/file.php
- 
-# remove read-only ##
-chflags noschg /path/to/file.php
-```

+如何在Linux/Unix中的Web服务根文档目录(DocumentRoot)上设置只读文件权限
+======
+我是如何对存放在/var/www/html/目录中的所有我的文件设置只读权限的？
+
+
+你可以使用`chmod`命令对Linux / Unix / macOS / Apple OS X / *BSD操作系统上的所有文件来设置只读权限。这篇文章介绍如何在Linux/Unix的web服务器（如 Nginx, Lighttpd, Apache等）上来设置只读文件权限。
+[![Proper read-only permissions for Linux/Unix Nginx/Apache web server's directory][1]][1]
+
+### 如何设置文件为只读模式
+
+
+语法为:
+
+```
+### 仅针对文件 ##
+chmod 0444 /var/www/html/*
+chmod 0444 /var/www/html/*.php
+```
+
+### 如何设置目录为只读模式
+
+语法为：
+```
+### 仅针对目录##
+chmod 0444 /var/www/html/
+chmod 0444 /path/to/your/dir/
+# ***************************************************************************
+# Say webserver user/group is www-data, and file-owned by ftp-data user/group
+# 假如webserver用户/用户组是www-data ,文件拥有者是ftp-data用户/用户组
+# ***************************************************************************
+# 设置目录所有文件为只读
+chmod -R 0444 /var/www/html/
+#设置文件/目录拥有者为ftp-data
+chown -R ftp-data:ftp-data /var/www/html/
+# 所有目录和子目录的权限为0445 (这样webserver用户或用户组就可以读取我们的文件)
+find /var/www/html/ -type d -print0 | xargs -0 -I {} chmod 0445 "{}"
+```
+找到所有/var/www/html下的所有文件（包括子目录），键入：
+
+```
+### 仅对文件有效##
+find /var/www/html -type f -iname "*" -print0 | xargs -I {} -0 chmod 0444 {}
+```
+然而，你需要在/var/www/html目录及其子目录上设置只读和执行权限，如此才能让web server能够访问根目录，键入：
+
+```
+### 仅对目录有效 ##
+find /var/www/html -type d -iname "*" -print0 | xargs -I {} -0 chmod 0544 {}
+```
+
+### 警惕写权限
+
+
+请注意在/var/www/html/目录上的写权限会允许任何人删除文件或添加新文件。也就是说，你可能需要设置一个只读权限给/var/www/html/目录本身。
+```
+### web根目录只读##
+chmod 0555 /var/www/html
+```
+在某些情况下，根据你的设置要求，你可以改变文件的属主和属组来设置严格的权限。
+```
+### 如果/var/www/html目录的拥有人是普通用户，你可以设置拥有人为： root:root 或 httpd:httpd (推荐) ###
+chown -R root:root /var/www/html/
+ 
+### 确保apache拥有/var/www/html/ ##
+chown -R apache:apache /var/www/html/
+```
+
+### 关于NFS导出目录
+
+你可以在/etc/exports文件中指定哪个目录应该拥有[只读或者读写权限 ][2] . 这个文件定义各种各样的共享在NFS服务器和他们的权限。如：
+
+```
+# 对任何人只读权限
+/var/www/html *(ro,sync) 
+ 
+# 对192.168.1.10(upload.example.com)客户端读写权限访问
+/var/www/html 192.168.1.10(rw,sync)
+```
+
+
+### 关于Samba (CIFS)只读共享对MS-Windows客户端
+
+
+共享sales为只读，更新smb.conf，如下：
+```
+[sales]
+comment = Sales Data
+path = /export/cifs/sales
+read only = Yes
+guest ok = Yes
+```
+
+### 关于文件系统表（file systems table）
+
+你可以在Unix/Linux上的/etc/fstab文件中配置挂载某些文件为只读模式。
+你需要有专用分区，不要设置其他系统分区为只读模式。
+
+如下在/etc/fstab文件中设置/srv/html为只读模式。
+```
+/dev/sda6 /srv/html ext4 ro 1 1
+```
+你可以使用`mount`命令[重新挂载分区为只读模式][3]（使用root用户）
+
+```
+# mount -o remount,ro /dev/sda6 /srv/html
+```
+或者
+```
+# mount -o remount,ro /srv/html
+```
+
+
+上面的命令会尝试重新挂载已挂载的文件系统在/srv/html上。这是改变文件系统挂载标志的常用方法，特别是让只读文件改为可写的。这种方式不会改变设备或者挂载点。让文件变得再次可写,键入：
+```
+# mount -o remount,rw /dev/sda6 /srv/html
+```
+或
+```
+# mount -o remount,rw /srv/html
+```
+
+### Linux: chattr 命令
+
+
+你可以在Linux文件系统上使用`chattr`命令[改变文件属性为只读][4],如：
+```
+chattr +i /path/to/file.php
+chattr +i /var/www/html/
+ 
+# 查找任何在/var/www/html下的文件并设置为只读#
+find /var/www/html -iname "*" -print0 | xargs -I {} -0 chattr +i {}
+```
+
+
+通过提供`-i`选项可删除只读属性
+```
+chattr -i /path/to/file.php
+```
+
+FreeBSD, Mac OS X 和其他BSD Unix用户可使用[`chflags`命令][5]:
+
+```
+### 设置只读 ##
+chflags schg /path/to/file.php
+ 
+### 删除只读 ##
+chflags noschg /path/to/file.php
+```
