#
# UserDir: The name of the directory that is appended onto a user's home
# directory if a ~user request is received.
#
# The path to the end user account 'public_html' directory must be
# accessible to the webserver userid. This usually means that ~userid
# must have permissions of 711, ~userid/public_html must have permissions
# of 755, and documents contained therein must be world-readable.
# Otherwise, the client will only receive a "403 Forbidden" message.
#
<IfModule mod_userdir.c>
#
# UserDir is disabled by default since it can confirm the presence
# of a username on the system (depending on home directory
# permissions).
#
UserDir disabled
#
# To enable requests to /~user/ to serve the user's public_html
# directory, remove the "UserDir disabled" line above, and uncomment
# the following line instead:
#
#UserDir public_html
</IfModule>
#
# Control access to UserDir directories. The following is an example
# for a site where these directories are restricted to read-only.
#
<Directory "/home/*/public_html">

什么时候该用这个 userdir.conf?
用来恢复缺失的默认文件、确认发行版本带了什么,或拿你的 Apache HTTP Server config 做 diff。
怎么恢复 Apache HTTP Server 的默认配置?
下载文件,把 /etc/httpd/conf.d/userdir.conf 里的当前配置备份好,替换掉,然后 reload 或 restart Apache HTTP Server。
userdir.conf 适合直接上生产吗?
这是 Red Hat Enterprise Linux 9 (Plow) 的厂商默认配置,只能当基线。上生产前请检查安全和性能设置。
和其他 OS 版本有什么不同?
默认值会随发行版和版本变化,这份对应 Red Hat Enterprise Linux 9 (Plow)。
我可以用它来排查 Apache HTTP Server 吗?
可以。和你的配置做 diff 找出漂移,然后只恢复需要的段落。
