apache 错误日志 debian 中的“无法打开日志”

[已解决] 更高的文件描述符限制解决了该问题

APACHE_ULIMIT_MAX_FILES='ulimit -n 65536'

我无法启动 apache2 服务：

[root@myhost ~]# service apache2 start
[....] Starting web server: apache2[Thu May 22 00:32:41 2014] [warn] NameVirtualHost *:443 has no VirtualHosts
Action 'start' failed.

 failed!

/etc/apache2/环境变量

# envvars - default environment variables for apache2ctl

# this won't be correct after changing uid
unset HOME

# for supporting multiple apache2 instances
if [ "${APACHE_CONFDIR##/etc/apache2-}" != "${APACHE_CONFDIR}" ] ; then
        SUFFIX="-${APACHE_CONFDIR##/etc/apache2-}"
else
        SUFFIX=
fi

# Since there is no sane way to get the parsed apache2 config in scripts, some
# settings are defined via environment variables and then used in apache2ctl,
# /etc/init.d/apache2, /etc/logrotate.d/apache2, etc.
export APACHE_RUN_USER=www-data
export APACHE_RUN_GROUP=www-data
export APACHE_PID_FILE=/var/run/apache2$SUFFIX.pid
export APACHE_RUN_DIR=/var/run/apache2$SUFFIX
export APACHE_LOCK_DIR=/var/lock/apache2$SUFFIX
# Only /var/log/apache2 is handled by /etc/logrotate.d/apache2.
export APACHE_LOG_DIR=/var/log/apache2$SUFFIX

## 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=''

有任何想法吗？

谢谢

答案1

/etc/apache2/envvars 中更高的文件描述符限制解决了该问题

APACHE_ULIMIT_MAX_FILES='ulimit -n 65536'

答案2

今天在 Apache/2.4.52 中遇到了同样的问题，通过取消注释 /etc/apache2/apache2.conf 中的 include ports.conf 解决了该问题：

sed -i 's/#Include ports.conf/Include ports.conf/g' /etc/apache2/apache2.conf
service apache2 restart
