## The locale used by some modules like mod_dav
export LANG=C
## Uncomment the following line to use the system default locale instead:
#. /etc/default/locale
export LANG
## The command to get the status for 'apache2ctl status'.
## Some packages providing 'www-browser' need '--dump' instead of '-dump'.
#export APACHE_LYNX='www-browser -dump'
## If you need a higher file descriptor limit, uncomment and adjust the
## following line (default is 8192):
#APACHE_ULIMIT_MAX_FILES='ulimit -n 65536'
## If you would like to pass arguments to the web server, add them below
## to the APACHE_ARGUMENTS environment.
#export APACHE_ARGUMENTS=''
## Enable the debug mode for maintainer scripts.
## This will produce a verbose output on package installations of web server modules and web application
## installations which interact with Apache
#export APACHE2_MAINTSCRIPT_DEBUG=1

什么时候该用这个 envvars?
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/apache2/envvars 里的当前配置备份好,替换掉,然后 reload 或 restart Apache HTTP Server。
envvars 适合直接上生产吗?
这是 Ubuntu 24.04 LTS (Noble Numbat) 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 Ubuntu 24.04 LTS (Noble Numbat)。
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。
